Sex and the City essays

Sex and the City essays In his day and age we are faced with threats no longer from armies and nations willing to take us over, now we face am enemy with no allegiance to the rules of warfare, with no remorse in taking innocent lives, these vile enemies are known as terrorists they will do anything to justify their cause. Terrorism seems to be increasing in number and in violence, no longer is political facilities at risk but also schools, public buildings etc, anything to bring attention to their cause. Due to all this the world needs some one to put a stop to this madness and thats how Rainbow Six was born. Rainbow Six was a new multi-national, anti-terrorist group set up by a coalition of governments to fight against the threat of international terrorism. The name of this group was chosen by John Clark the head of the organization, due to its international nature. Rainbow was a 'black' organization, meaning it officially did not exist, the controlling governments would deny any knowledge of it. Rainbow was formed to deal with the ever-increasing threat of terrorism. Formed from the top anti-terrorist operatives from the different organizations around the world, making an elite unit now known as Rainbow. Rainbow was based in Hereford, England, the home of the British Army's 22nd Special Air Service Regiment. ...

â€Å"Perhaps, properly speaking, Dickens had no ideas on any subject; what he had was a vast sympathetic participation in the daily life of mankind; and what he saw of ancient institutions made him hate them, as needless sources of oppression, misery, selfishness, and rancour.† –George Santayana Rules.

Upon closer inspection, we see that Wemmick plays host to two polar personalities: the hard working, upstanding worker in bustling London, and the amiable, carefree resident of Walworth. Through careful examination of Wemmick’s character, Dickens prompts his reader to reflect upon the two sides of humanity as a whole. In Victorian society, employees were expected to carry themselves with a degree of professionalism and excellence.

Initiation of the KERP projects programme and the execution of the Movie Review

Initiation of the KERP projects programme and the execution of the First project by Kuwait oil company - Movie Review Example Kuwait Environmental Remediation Program (KERP) aims at dealing with the elimination of pollutants or impurities from environmental media resulting from the oil explosion. KERP seeks to ensure the realization of three key objectives. The first objective is to direct Kuwait National Focal Point (KNFP) in the accomplishment of the KERP. The second objective is to undertake remediation of damaged terrestrial resources by means such as fencing and patrolling of five designated areas. The third objective is to remedy areas damaged by oil leaks, oil contaminated piles, oil trenches, and oil spills. Military contributed to Kuwait’s environmental damages through a series of activities. The movement of vehicles and heavy weaponry damaged the delicate desert environment by affecting the plant cover that in turn affected the sensitive ecosystem. The physical esthetic value of the environment in turn was destroyed, and aridity started engulfing the lands of Kuwait. In 1994, Kuwait government submitted environmental claims that aimed at monitoring and realizing remediation mechanisms to restore and improve Kuwait’s ecological status. After studies on the same subject matter, in the period 2001 to 2007, Public Authorities for the Assessment of Compensation proposed remediation technologies to enable rehabilitation of the damaged environment. The steps are aimed at bringing recovery and restoration to the deteriorated environmental status in Kuwait. On August 2, 1990, the State of Kuwait sustained extensive environmental damages because of the Iraqi aggression against Kuwait and the 1991 Gulf War. The United Nations Compensation Commission (UNCC) recognized the provision of reparations to affected countries, companies and individuals. In December 2005, the UNCC completed the appraisal of all claims for environmental damages in visualization of remediating environmental damages. The UNCC issued Decision 258

The policy regime that governed the expansion of the electricity Essay

The policy regime that governed the expansion of the electricity system in the last century is a barrier to decarbonisation - Essay Example In Ontario, several policy regimes were created in the effort of achieving decarbonisation. In this essay, I will examine the policy regime that was enacted by the Ontario government, as well as, how they have helped and diminished the achievement of clean electric energy in the province. In Ontario to ensure that there were appropriate regimes to run the introduction of the clean energy and to avoid competition, the government enacted the Ontario Power Authority in 2004. The Act was enacted to conduct autonomous electricity system planning and to procure electricity resources. Although the policy regimes were meant to end decarbonisation in Ontario, some of the policy makers were main profit out of the regimes (Winfield,  2012). Instead of focusing on measures to decarbonize Ontario and ensure that there is clean environment focused on the market discipline and competition on renewable energy. In that, according to the Advisory Committee on Competition in Ontario’s Electricity System, the policy that was created was not intended to encourage renewable energy. The Committee further argued that Ontario customers needed electricity that was genera ted by renewable resources where they would choose it in a new market that would be introduced. The politics in en ergy have been a great barrier in the achievement of decarbonisation. Therefore, to ensure that political polarization on renewable energy is reduced proper measures should be given to ensure that debates on renewable energy were not based on politics. Secondly, the policy regimes that were created in the last decade were a barrier to decarbonisation. Because instead of supporting renewable energy in Ontario the government was delaying the opening of electricity by maintaining the introduction of market and competition forces, which were all needed to promote renewable energy (Pond,  2009). The government did not consider that by delaying the regimes in the province they were causing many

Post devolution, do separate or dual identities exist in England and Dissertation

Post devolution, do separate or dual identities exist in England and Britain - Dissertation Example Such assumptions were based on the esoteric understandings of the two labels, British and English, and tended to affect the framing of the concept of a so called national identity that were based on territorial differentiation and the respective identities, nature of citizenship, and social inclusion. The nationalistic identity of any state which is dependent on its socio-political characteristics, may go through various transformations (like devolution); and under pressures from the changed local, political, and social conditions, may undergo differentiation. Under changed circumstances the nationalistic identity of ‘Britishness’ may take a back seat, with the regional identity of ‘Englishness,’ eclipsing the former. ... The Existence of Separate or Dual Identities in England and Britain post devolution period 1 Introduction 1.1 Background History â€Å"The history of England [is] not in England but in America and Asia† J.R. Seele Since 1997, United Kingdom has been undergoing devolution as regards to its 4 member states, England, Wales, Northern Ireland, and Scotland. England has been ‘eventually promised’ a new and ‘Greater London Authority,’ with a separate and Assembly and mayor, while separate regionally elected assemblies are also on the annals for England; while the remaining 3 states have been given varying degrees of autonomy in their assemblies. Thus this entire process of devolution spells out into new territorial contours within the realms of United Kingdom. A look at the history shows us that Britain did not quite have a homogenous nature right from the time of its conception, and the then British foreign secretary Robin Cook, ascertained that the concept of this â€Å"homogeneity of British identity that some people assume to be the norm was confined to a relatively brief period. It lasted from the Victorian era of imperial expansion to the aftermath of the Second World War...The diversity of modern Britain expressed through devolution and multiculturalism is more consistent with the historical experience of our islands† (Cook, 2001). The topic or concept of ‘British,’ after being reviewed by various experts has been found to consist of a large and gaping conceptual void (Kumar, 2000, 576). Historical records, in general, are found aplenty, starting with political, constitutional, social, and economic histories of England, yet there has

Gautam Buddha Essay Example for Free

Gautam Buddha Essay Gautama Buddha, also known as Siddhartha Gautam, Shakyamuni, or simply the Buddha, was a spiritual teacher from ancient times and the founder of Buddhism. He is universally recognized by Buddhists as the Supreme Buddha (Sammasambuddha) of our age. Yet his exact date of birth and death is uncertain but a majority of historians date his lifetime from circa 623 B. C. to 543 B. C. He is one of the few luminaries in the history of humans who is such a wide and lasting influence to the people. There are countless stories of the Buddha each tradition, each culture, each time period has their own stories . It is believed that, immediately after his birth he took seven steps and on each step a lotus blossomed which represents the seven colours of rainbow. The tales say he was a son of a king raised in a palace with every imaginable luxury, he was called Siddhartha Gautama-a prince among a clan of warriors â€Å"When I was a child† he said â€Å"I was delicately brought up most delicately, a white sunshade was held over me day and night to protect me from cold, heat, dirt and dust. My father gave me three lotus’s ponds one where red lotuses bloomed, one where white lotuses bloomed, one where blue lotuses bloomed† Pali talkie Gautam Buddha is the key figure in Buddhism. Discourses, and monastic rules were summarized only after his death and memorized. Passed down by oral tradition, the Tripitak- the holy book of Buddhism is also written on pali language only after 400 years of his death which is divided into 3 parts 1st the rules that a Buddhist monk needs to follow, 2nd Buddha’s admonition and 3rd Accounts of Buddha’s life. Siddartha Gautam: Siddhartha Gautam was born in southern Nepal at the foot of the Himalayas on the famous gardens of Lumbini, which is located in the Terai plains of southern Nepal, testified by the inscription on the pillar erected by the Mauryan Emperor Asoka in 249 B. C. Siddhartha was a child with a contemplative bent of mind. He was inclined towards meditation and spiritual pursuits much against the wishes of his father. His father feared that Siddhartha might leave home, and so, kept tried to insulate him from the harsh realities of the world outside by keeping him inside the palace all the time. Sealed from pain and suffering Siddhartha indulged in a life of pure pleasure. Every whim satisfied every desire fulfilled. The Buddha once said â€Å"During the rainy season I stayed in my palace where I was entertained by musicians and dancing girls I never thought of leaving. † when he was sixteen his father draws him in tighter in to palace life, married him to his cousin which wasn’t long before they fell in love. But one day when he goes outside travelling through the kingdom, and he has the first of four encounters he sees an old man and he ask his attendants and attendants replied oh! That is the change, no human being could stay young everybody needs to grow old. Then on his next tour outside he sees a sick man and doesn’t quite understand what it is, again he ask his attendants then his attendants replied oh! That happens to all of us everybody gets sick and don’t think you are a prince and you don’t get sick your father, your mother everybody will become sick. Then he sees that it isn’t just a sick person in fact it’s the universal and something is stimulated inside of him so he keeps getting the chariot to take him out then he sees horror after horror. And on his third trip outside he meets a corps then he recognizes impermanence, suffering and death as a real state of things, the world that he has been protected, sealed or kept from seeing and he was shocked then he realized this is my fate too I will also become old I will also become sick and eventually I will also die, how do I deal with these things. And then on his fourth trip outside he sees the spiritual seeker someone who was decided to live a life completely other than his life in order to escape impermanence, sufferings and death. Soon after he left his family and Kingdom at the age of 29 and went into the forest in search of peace and truth. Siddhartha was alone in the world for the first time, on the bank of the nearby river he drew his sword â€Å"although my father and step mother were grieving with tears on their faces† Siddhartha said â€Å"I cut of my hair I put on the yellow robes and went forth from home into homelessness. I have been wounded by the enjoyment of the world and I had come out longing to obtained peace. † Then he wandered from place to place to gain knowledge. He met many cholars and saints but he was not satisfied. At last he started hard meditation bearing great physical suffering. Emaciated, exhausted Siddhartha tortures’ himself trying to destroy anything within himself that he sees it’s bad. It is said that Siddhartha had lived many life before this one as countless animals, innumerable human beings and even gods across four incalculable ages that secret text say and many eons experiencing life in all at different forms. The Buddha: Gautam Buddha seated under a pipal tree—now known as the Bodhi tree—in Bodh Gaya small town in north eastern India. For Buddhist there are hundreds of holy places but none more sacred than Bodh Gaya. It is the sacred point from which the buddhits faith radiates. It is their mecca or jeroselum or any other initiation forms of initiator. Then he vowed never to arise until he had found the truth so he sat down with his rags he was wearing under the shade of Bodhi tree at the bank of the river and began to meditate. It was spring time with a full moon on the sky at night, before the sun would rise Siddhartha’s long search would be over. Siddhartha now got transformed into Buddha or the enlightened one at the age of the thirty five. The pipal tree under which he got Enlightment came to be known as Bodhi Vriksha. Buddha saw nature of the people envy, jealousy and strong negative mental stage. He analyzed all the people in the world they are like the fishes riddling in the very shallow water. So Buddha he himself is afraid to teach the people. Then, the myth says the god BRAHMA himself comes to the Buddha kneeling down and asked Buddha to teach people what he had gains during all his life BRAHMA implies that is what every human needed to satisfied one’s life otherwise the human life would never be fulfilled. And then Buddha decided to give his teachings. For the remaining 45 years of his life, the Buddha devote his rest of his life bringing his teachings the â€Å"Dharma† the fundamental laws of all things into the world. He preached his first sermon in Sarnath, near Varanasi. He taught that the world is full of sorrows and people suffer on account of desire. Hence desires needed to be conquered by following Eightfold Path. Of these eight paths, the first three would ensure physical control, the next two ensures mental control, and the last two would ensure intellectual development. It is said that the Buddha traveled in the Gangetic Plain, in what is now Uttar Pradesh, Bihar and southern Nepal, teaching a diverse range of people: from nobles to outcaste street sweepers, murderers such as Angulimala, and cannibals such as Alavaka. Cast was irrelevant to the Buddha so his teachings focused within the universe. From the outset, Buddhism was equally open to all races and classes, and had no caste structure, as was the rule for most Hindus in the-then society. Bliss, nirvana the Buddha taught could be found in a freeing movement through the practice of meditation the Buddha showed to his followers how to come to the terms with their own roiling thoughts and desires by paying attention to them, by becoming aware becoming mindful. What Buddha realizes is that if we can get rid of this fundamental misunderstanding of the nature of itself based on egotism, we won’t screw up everything we do, because we are thinking about it in a wrong way. Once you stop centering your feelings about feelings on yourselves, what naturally arise are simple compassions, compassions for your own sufferings and others as well. For decades the Buddha shared his teachings all across north eastern India that all beings are happy, he taught weak or strong, great or small. He said let us cherish all creatures as a mother her only child. Bare foot in his robes he was still walking along the roads when he was eighty an old age was upon him his back hurt, his stomach was often in pain, â€Å"I am old worn out† he told to a trusted disciple â€Å"like a deflated craft held together within straps†, the world is so sweet he said that he could understands to wanting to live at least another century but he was fragile and exhausted he become ill at the village named Kushinagar near Nepal. Kushinagar is revered by the pilgrims where the Buddha finally left this world. It was in Kushinagar where he grew weak and has to laid on his side in a quite grove of Sal trees as near the end his disciples began to weep striking with grief. But the Buddha reassured them that all things change he said whatever is born is subject to decay. He was saying these is natural process he tells his disciples, use this time, use the energy here even this, for your own awakening , so he use even his own death and their sadness as a time to remind them of what they real task was. In short: Now, Buddhism is more than 2500 years old there are more than 350 million followers in the world who follows Buddhism. The gist is Buddhism arose as a result of Siddhartha Gautam’s quest for Enlightenment in around the 6th century BC. There is no belief in a personal God in Buddhism. It is not centered on the relationship between humanity and god. Buddhists believe that nothing is fixed or permanent- change is always possible. The two main Buddhist Sects are Theravada Buddhism and Mahayam Buddhism, but there are many more. There is not particular place where Buddhists can worships they can worships both at home or at a temple. The path to enlightenment is through the practice and development of morality, mediation and wisdom. â€Å"It may be that after I am gone that some of you will think that now we have no teacher but that is not how you should see it, let the dharma and the discipline that I have taught you be your teacher, all individual things pass away strive on untiringly† Buddha’s last words. The fundamental need for the peace is the peace in the individuals mind. We can give others only the values and idea that we possess. Only the happy and satisfied person, therefore, can provide the happiness and love to others and be able to unite people. The present world situation is the result of our way of thinking. World peace is possible only when all the people love each other. If everybody thinks about each other we would not have problems, but we are habitual in our thinking and define everything according to ourselves or group or community or country. If we steal from another, we steal from ourselves. Instead, we should learn to give and take care of things that belong to our family, to the school, or to the public. Proper conduct shows respect for oneself and others. Our bodies are gifts from our parents, so we should protect them from harm. Young people should especially keep their natures pure and develop their virtue. It is up to them to make the world a better place to live. Religion is religion only when it unites people and not if divides. We therefore, need conversation from leaders to masters, religious persons to spiritual persons to achieve a level of World Peace.

Properties of Topological Insulating Material: Bi2Te3-PANI

Properties of Topological Insulating Material: Bi2Te3-PANI Synthesis, Characterization and Electrical properties of a Composite of Topological Insulating Material: Bi2Te3-PANI R. R. Urkudea[*], P. T. Patilb, S. B. Kondawarb, U. A. Palikundwara[† ] aX-ray Research Laboratory, Department of Physics, Rashtrasant Tukadoji Maharaj Nagpur University, Nagpur 440033, India bPolymer Nanotech Laboratory, Department of Physics, Rashtrasant Tukadoji Maharaj Nagpur University, Nagpur 440033, India Abstract In the present work, we carried out a systematic study of structure, UV-Vis Spectra and surface conductivity of pure Bi2Te3, pure Polyaniline (PANI) and Bi2Te3 (5%)-PANI (95%) composite. Bi2Te3 was synthesized by a method similar to solvothermal method, whereas, pure PANI and Bi2Te3-PANI composite were synthesized by a chemical oxidative method. The materials were structurally characterized and the electrical properties were investigated in the temperature range from room temperature to 100 °C. The electrical conductivity of the Bi2Te3-PANI composite is found to be higher than that of its pure constituents at all the temperatures. The enhancement in the surface conductivity may be due to the PANI generated ordered molecular arrangement of Bi2Te3 in the Bi2Te3-PANI composite, as confirmed from powder x-ray diffraction, UV–vis spectral analysis.  © 2015 The Authors. Published by Elsevier Ltd. Peer-review under responsibility of the International Conference on Nanomaterials and Technologies (CNT 2014). Keywords: Topological insulators; Bismuth telluride; thermoelectric material; Polyaniline composites; electrical conductivity. 1. Introduction Topological insulators (TIs) are electronic materials that have a bulk band gap like an ordinary insulator but have protected conducting states on their edge or surface (Hasan and Kane, 2010). Most of the current researches are focused on the materials, like Bismuth telluride (Bi2Te3), Antimony telluride (Sb2Te3) and Bismuth selenide (Bi2Se3) due to the topological insulating properties exhibited by them. Bi2Te3 is one of the best TI materials. It is a semiconducting compound with narrow bulk band gap of 0.2 eV. It is also a good material for thermoelectric applications (Das and Soundararajan, 1988). It has shown a drastic change in its thermoelectric properties when it is doped with Polyaniline (PANI) (Li et al., 2011). It has also given added advantages of polymers like inexpensiveness, intrinsically low thermal conductivity, flexibility and good processability etc. (Marjanovic et al., 2013). Various research workers have attempted to synthesize and characterize composites of Bi2Te3 with polyaniline (Zhao et al., 2002; Xu et al., 2005; Hostler et al., 2006; Chatterjee et al., 2009; Toshima et al., 2011). Very recently, mechanical blending method was employed by Li et al. (2011) for the synthesis of Bi2Te3–PANI; they found that the power factor of the composite is less than both of the individual components. However, a report on the synthesis of a Bi2Te3 and PANI hybrid by physical mixing and solution mixing showed a higher power factor in the case of the physical mixture (Toshima et al., 2011). Though there is a vast literature available on the TE properties of Bi2Te3-PANI composites, experimental reports on TI Properties of the composites are not available. Based on this background, in the present work, we carried out a systematic study of structure, UV-Vis Spectra and surface conductivity of Bi2Te3 (5%)-PANI (95%) composite, pure Bi2Te3 and pure PANI. Bi2Te3 was synthesized by a method similar to solvothermal method (Deng et al., 2002), whereas, pure PANI and Bi2Te3-PANI composite were synthesized by a chemical oxidative method (Stejskal and Gilbert, 2002). The materials were structurally characterized and the electrical properties were investigated in the temperature range from room temperature to 100 °C. The electrical conductivity of the Bi2Te3-PANI composite is found to be higher than that of its pure constituents at all the temperatures. The enhancement in the surface conductivity may be due to the construction of highly ordered chain structures of PANI on Bi2Te3, as confirmed from powder x-ray diffraction (XRD), UV–vis spectral analysis. 2. Experimental details 2.1 Materials used Bismuth chloride (BiCl3), Tellurium (Te) metal powder, Potassium hydroxide (KOH), Sodium borohydrate (NaBH4), N-N dimethylformamide (DMF), Hydrochloric acid (HCl), Aniline (C6H5NH2), Acetone [(CH3)2.CO], Methanol (CH3OH) were purchased from Merck Chemicals. Ammonium persulphate [(NH4)2S2O8] was purchased from Hi-media. All the chemicals were of analytical reagent grade and are used without further purification, except aniline which was purified prior to use. 2.2 Preparation of Bi2Te3 A mixture of BiCl3 (10 mmol), Te powder (15 mmol), KOH (80 mmol) and NaBH4 (30 mmol) were put into a beaker of 100 ml capacity. The beaker was then filled with N-N dimethylformamide (DMF) up to 90 ml and was kept into a muffle furnace. Temperature of the furnace was maintained at 100-180 °C for 24 hours and was then slowly cooled to the room temperature. The product was filtered, washed with double distilled water and dried in vacuum oven at 80 °C for 12 hours. 2.3 Preparation of pure PANI and Bi2Te3 PANI Composite PANI was synthesized by using chemical oxidative method (Stejskal and Gilbert, 2002) 0.2 mol Aniline with 0.25 mol Ammonium persulphate was oxidized in acidic aqueous medium. Aniline and Ammonium persulphate were dissolved, separately, in 50 ml solution of 1.0 mol HCl in double distilled water. Both the solutions were kept at room temperature for 1h and were mixed together in a beaker. During the process, the colour of the solution changed from colourless to light blue and then to dark green. The solution was briefly stirred and was left to polymerize for 24 h. The precipitate of PANI was collected on a filter paper, washed with distilled water, then with 20 ml of 0.1M HCl and with Methanol. PANI (emeraldine salt) powder was dried in vacuum oven at 80 °C. A similar procedure was followed for the synthesis of Bi2Te3-PANI composite, but this time Bi2Te3 was introduced in aniline solution. 3. Characterization 3.1 Structural characterization The samples were structurally characterized by XRD and UV–vis spectral analyses. XRD measurements were performed using a Diffractometer (Rigaku Miniflex II x-ray Diffractometer) with Cu KÃŽ ± radiation (ÃŽ » = 1.541838 A °). The UV–vis spectra of the prepared samples were recorded by a spectrophotometer (UV-1800 Shimatzu Spectrophotometer) using samples dissolved in dimethyl formamide in a quartz cuvette. 3.2 Electrical characterization All the prepared samples were pressed at pressure less than 5 tonnes, at room temperature, to form the compacted pellets for measurement of the electrical conductivity. The measurements were carried out, in the temperature range 20-100  °C, by standard four-probe method with constant current source kept at 2 mA. 4. Results and Discussions 4.1 Powder X-ray diffraction Figure 1 shows the XRD patterns of Bi2Te3, pure PANI and Bi2Te3-PANI composite. All the peaks of the pattern for Bi2Te3 can be indexed in rhombohedral structure (JCPDS No: 015-0863) with unit cell parameters: a = 4.358A °; b = 4.358A ° and c = 30.48A °. Broad peaks at 22 ° and 25 ° for pure PANI are observed, which are due to the repeat unit of monomer. Compared with the pure PANI, only one peak is clearly observed at 25 °, the same position, in the XRD pattern of Bi2Te3-PANI composite. The observation of a single peak is related to the monodistribution of the periodicity of the repeat unit of the PANI and ordering of the molecular arrangement of the Bi2Te3 in the PANI matrix (Talwar et al., 2014). This suggests that PANI generate an ordered molecular arrangement of Bi2Te3 in the Bi2Te3-PANI composite. Figure 1 XRD patterns of Pure PANI, Pure Bi2Te3 and Bi2Te3-PANI composite 4.2 UV-vis spectroscopy Figure 2 shows the UV–vis spectra of the samples used to explore the electronic states of Bi2Te3, pure PANI and the Bi2Te3-PANI composite. A characteristic band centred at 697 nm, a shoulder at 478 nm, corresponding to a polaronic transition (polaron- Ï€*) and a band around at 389 nm, assigned to the π–π* electron orbital transition are observed in Bi2Te3-PANI composite. In comparison with UV–vis spectra of the pure PANI: a band around 385 nm, assigned to the π–π* electron orbital transition, shifts to longer wavelength at 389 nm in Bi2Te3-PANI composite. The polaronic transition (polaron- Ï€*) is absent in the pure PANI but is observed in Bi2Te3-PANI composite. These show an interaction between the quinoid ring of PANI and Bi2Te3 (Xia and Wang, 2003). This is a signature of an ordered molecular arrangement in Bi2Te3-PANI composite and it is the purely surface conducting state. Figure 2 UV-vis spectra of Pure PANI, Bi2Te3 and Bi2Te3-PANI composite 4.3 Electrical characterization Figure 3 Variation of the electrical conductivity with temperature of Bi2Te3, PANI and Bi2Te3-PANI composite. The variations of electrical conductivity as a function of temperature of the prepared samples are shown in figure 3. The value of electrical conductivity for Bi2Te3 slightly decreases with the increase in the temperature. However, both PANI and Bi2Te3-PANI composite show increase in the value of electrical conductivity with temperature. The electrical conductivity of the Bi2Te3-PANI composite is higher than that of its pure constituents over a whole temperature range. The enhancement in the surface conductivity indicates the increase in protected states at the surface compared to that of the pure Bi2Te3. This may be due to the large surface provided to the Bi2Te3 by the PANI generated ordered molecular arrangement of Bi2Te3 in the Bi2Te3-PANI composite. 5. Conclusions In conclusion, we carried out a systematic study of structure, UV-Vis Spectra and surface conductivity of Bi2Te3 (5%)-PANI (95%) composite, pure Bi2Te3 and pure PANI. Bi2Te3 was synthesized by a method similar to solvothermal method, whereas, pure PANI and Bi2Te3-PANI composite were synthesized by a chemical oxidative method. The materials were structurally characterized and the electrical properties were investigated in the temperature range from room temperature to 100 °C. The electrical conductivity of the Bi2Te3-PANI composite was found to be higher than that of its pure constituents at all the temperatures. The enhancement in the surface conductivity may be due to the PANI generated ordered molecular arrangement of Bi2Te3 in the Bi2Te3-PANI composite, as confirmed from powder x-ray diffraction (XRD), UV–vis spectral analysis.
