The stability and applicability of new cadmium complex, Cdmq2, is investigated for electroluminescent device application. The Cdmq2 is characterised by different characterisation techniques. It shows excellent thermal stability up to 440 °C. A maximum is observed at 390 nm in absorption spectra which attributed to π - π* transition. Organic light emitting diode (OLED) has been fabricated using this material. The integral parts of the device were ITO/α-NPD/Cdmq2/BCP/Alq3/LiF/Al. Electroluminescence (EL) device emits yellowish green light with maximum luminescence 1185 cd/m2 at 23V.

In this paper, we expounded the superconductive nature for fullerenes, which are being explored for the molecular electronics applications. The fullerene we picked for our research work is the C24 which was then doped with popular dopants- Boron, Nitrogen and Phosphorus and the self-consistent calculations were performed in the configuration where molecule was bridged between the gold electrodes using MCBJ (Mechanically Controlled Break Junctions) technique at sub-zero temperature of 0.100K. The characteristics of these variants of doped C24were compared with that for pure C24 and the results clearly demonstrated the electrical superiority of the pure C24 over its doped counterparts for cryogenic applications of electronics. This paper would represent another mark in the field of molecular electronics that prefer carbon or organic materials as competing future in nanotechnology for military and defence applications.
本文阐述了富勒烯的超导性质,并对其在分子电子学上的应用进行了探索。我们为我们的研究工作选择的富勒烯是C24,然后掺杂了流行的掺杂剂-硼,氮和磷,并在0.100K的零下温度下使用MCBJ(机械控制断结)技术将分子桥接在金电极之间的配置中进行自一致计算。将这些掺杂C24变体的特性与纯C24的特性进行了比较,结果清楚地表明纯C24比掺杂C24在电子低温应用中的电学优势。这篇论文将代表分子电子学领域的另一个标志,即碳或有机材料更倾向于在军事和国防应用的纳米技术中竞争未来。

Cadmium Sulphide (CdS) thin films were deposited on glass substrates by sol-gel spin coating method taking cadmium nitrate and thiourea as the precursor solutions. The influence of annealing temperature on the structural, optical and surface morphological properties of the films was studied. The crystallographic structure and crystallite size were determined from the X-Ray Diffraction study. It reveals that the films have a predominant hexagonal crystal phase with a preferential (0 0 2) plane. Transmittance of the deposited films was significantly higher in the visible region. The calculated optical band gap of the films decreases with increase in annealing temperature. The photoluminescence spectra show that the intensity of PL emission peaks found to decrease in intensity, with increase in annealing temperature. SEM studies reveal that the grains are spherically shaped and distributed uniformly over the entire surface of the substrate. These examined properties of the films show its feasibility for application in optoelectronic devices, especially for solar cells.
以硝酸镉和硫脲为前驱体,采用溶胶-凝胶自旋镀膜的方法在玻璃衬底上制备了硫化镉薄膜。研究了退火温度对薄膜结构、光学和表面形貌的影响。通过x射线衍射研究确定了晶体结构和晶粒尺寸。结果表明,薄膜以六方晶相为主,具有优先的(0 0 2)平面。沉积膜在可见光区的透光率显著提高。薄膜的光学带隙随退火温度的升高而减小。光致发光光谱显示,随着退火温度的升高,发光峰的强度逐渐减小。扫描电镜研究表明,颗粒呈球形,均匀分布在整个基体表面。这些特性表明了薄膜在光电器件,特别是太阳能电池中的应用可行性。

We report on a quantum dot sensitized solar cell based on Combination of VACNT/ZnO/CdSe. The electron lifetime for VACNT/ZnO/CdSe is longer than that for ZnO/CdSe combination, indicating that the charge recombination at the interface is reduced by the presence of the VACNT. A power conversion efficiency of 1.46% is achieved for the VACNT/ZnO/CdSe due to the increased surface area and longer electron lifetime. The choice of Quantum Dots in respective of properties needed for high efficiency is necessary, we had analyzed Quantum dots having better absorption coefficient for photon power per energy, resultant absorbed power was calculated from variation of Energy flux per photon energy with respect to variation of photon energy (eV). CdSe hit maximum values compared to Competitors, Moreover CdSe join hand with various Transparent Conducting layer for profession of Exciton Concentration for different Pump power pulse. Out of Respective analysis of respective combination, CdSe/VACNT credit more than that of others because of its enormous identical Structural Properties of VACNT and Quantum size effect of CdSe.
报道了一种基于VACNT/ZnO/CdSe复合材料的量子点敏化太阳能电池。VACNT/ZnO/CdSe的电子寿命比ZnO/CdSe组合的电子寿命长,表明VACNT的存在减少了界面处的电荷复合。由于增加的表面积和更长的电子寿命,VACNT/ZnO/CdSe的功率转换效率达到1.46%。量子点的选择是为了提高效率所必需的,我们分析了量子点对每能量的光子功率有更好的吸收系数,所得的吸收功率由每光子能量的能量通量相对于光子能量(eV)的变化来计算。与竞争对手相比,CdSe达到了最大值,并且CdSe与各种透明导电层一起用于不同泵功率脉冲的激子浓度专业。在对各自组合的分析中,CdSe/VACNT由于其与VACNT的结构特性和CdSe的量子尺寸效应有着巨大的相似性,因此比其他组合的贡献更大。

This paper describes the application of carbon nanotubes(CNT) in injection thrust vectoring of rocket motors using multiple plume spray pattern system. The CNTs are a new dimension in thrust generation. They have an exceptional quality of photoreaction, thermal conductivity and directional guidance. Using its ability to produce and guide thermo power waves, it is added as a fuel additive to produce CNT propulsive fluid which has the power to enhance thrust even at low volumes. The fluid is injected into the rocket engine main exhaust in the required direction at the aft end of the nozzle using multiple plume spray pattern system for efficiency. This enhancement is used for thrust vectoring of a rocket, which is the only way for attitude control. Its usage reduces the load factor of an extra fuel tank.

This paper reports on the structural and optical properties of Mg doped ZnO nanoparticles through sol-gel method using polyvinyl alcohol as chelating agent. For studying the effect of Mg doping on particle size and morphology, the prepared samples were characterized by using X-ray diffractometer, and Field Emission Scanning Electron Microscope (FE-SEM). The optical properties of the samples were investigated by UV-Vis spectroscopy (UV-Vis), and Fourier Transform Infrared Spectroscopy (FTIR). The particles size was evaluated using Scherrer's formula from XRD patterns. It was observed from XRD studies that the particles size decreased with increasing Mg concentrations. It is observed from FE-SEM microstructure that the grain size of the samples decreased with increasing Mg doping. The samples exhibited a blue shift in absorption in UV spectra indicating good optical properties.

In the present investigation efforts are made to prepare CdZnSSechalcogenide thin films by simple, cost effective arrested precipitation technique (APT). The films were obtained in a chemical bath maintained at 55±5°C temperature, pH 10.8±0.2 and deposition time 90 min. The obtained thin films were thoroughly characterized paying particular attention to their structural, compositional, morphological and optical properties. The surface morphology and composition of as deposited thin films are studied by using Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDS). SEM micrographs reveal non- uniform distribution and nearly spherical grains. The X-ray diffraction pattern showed that highly textured CdZnSSe films with hexagonal structure.

As day by day there is technological development seen all around the world, the research work is progressing but the resources involved in them are depleting rapidly. The demand of resources and fuels for the technological development is increasing day by day. In order to keep the pace of development high we need to think about some alternate fuel with better efficiency which would help overcome the demand keeping in mind the resources for the future generation. An alternate fuel needs to be developed and researched upon which could help us get greener and better tomorrow. In this paper I would like to highlight upon the usage of Diesel, Castor Oil and Nano Particles for a compression ignition engine and study the performance characteristics of this fuel at different mixing ratios.

In this paper I would like to highlight upon the usage of Diesel, Castor Oil and Nano Particles for a compression ignition engine and study the performance characteristics of this fuel at different mixing ratios.","PeriodicalId":13708,"journal":{"name":"International Conference on Advanced Nanomaterials & Emerging Engineering Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73181004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The heat transfer ability of a device can be altered by changing the heat transport properties of a fluid thus helping in miniaturization of electronic devices. In the present work the thermal conductivity of a copper heat pipe has been increased with titanium oxide nanofluid. The titanium oxide nanofluids are prepared using the two step process by sol gel technique followed by ultasonication. There was no sedimentation of the nanoparticles for 15 days showing high stability of nanofluid. TiO2 nanoparticles with an average diameter of 8.47nm was produced by sol gel method. The volume fraction of the nanoparticles were fixed and input power conditions were varied to study the heat transfer rate.
通过改变流体的传热特性,可以改变器件的传热能力,从而有助于电子器件的小型化。在本研究中,用氧化钛纳米流体提高了铜热管的导热系数。采用溶胶-凝胶法和超声法两步法制备氧化钛纳米流体。纳米颗粒在15天内没有沉淀,显示出纳米流体的高稳定性。溶胶-凝胶法制备了平均粒径为8.47nm的TiO2纳米颗粒。固定纳米颗粒的体积分数,改变输入功率条件,研究纳米颗粒的传热速率。
