In Situ Functionalized Fluorescent WS2-QDs as Sensitive and Selective Probe for Fe3+ and a Detailed Study of Its Fluorescence Quenching
No full textMost of the reports suggest that liquid exfoliated WS2-QDs are unstable; therefore the need of present day is to develop a novel synthesis route for producing long-term stable WS2-QDs. Herein, we report a bottom-up single-step hydrothermal growth of in situ functionalized blue fluorescent WS2-QDs with stable fluorescence in aqueous media without subsequent treatments. Presence of various functional groups over the surface of f-WS2-QDs provides high solubility and stability to f-WS2-QDs in aqueous media preserving its fluorescence. Further, photoluminescence property of f-WS2-QDs has been employed to devise an optical sensor with a high sensitivity (K-D similar to 10(4) M-1) and selectivity for ferric (Fe3+) ions. Under the optimal condition, response of the sensor is found to be linear in the range of 0-55 mu M with a limit of detection (LOD) of 1.32 mu M, which is within the maximum permissible level of Fe3+ (similar to 5.4 mu M) in human drinking water by the USEPA. Further, we have also carried out a detailed evaluation on fluorescence quenching kinetics of f-WS2-QDs. Nonlinear behavior of S-V plot and TRPL measurements suggest that quenching is a mixed phenomenon of dynamic as well as static processes. Finally we have proposed a mechanism for fluorescence quenching of f-WS2-QDs in the presence of Fe3+.

Materials Development for Gallium Nitride Power Devices
No full textGallium Nitride has gained prominence in the field of power electronics due to its high bandgap, high critical electric field, high mobility and high saturation-drift velocity. This means that GaN can be used to make devices that have a low on-resistance along with a high breakdown voltage. High frequency GaN HEMTs have been commercially available since 2006 and still being improved. The high power market is just starting to tap into GaN devices. Vertical transistors are especially attractive for high power applications, as they provide the possibility of a high breakdown voltage at a low chip size, thus, a low cost price. In addition to this, GaN devices can also use the two-dimensional electron gas formed at the GaN/AlGaN heterojunction to obtain a higher current.Several GaN based power devices are being investigated - both vertical and lateral. Our group has been focusing on the Oxide GaN-interlayer Field Effect Transistor (OGFET) and the Current Aperture Vertical Electron Transistor (CAVET). On the lateral side, power HEMTs are being developed. This work focuses on materials development for the various types of power devices. A primary motive for this thesis is for it to serve as a reference manual for researchers working on GaN power devices. Vertical power devices are united by a common feature – a thick drift region with a low n-type carrier concentration. Through simulations, it has been shown that the optimal carrier concentration to simultaneously achieve a low Ron and a high breakdown voltage is about 1 x 1016 cm-3. Through our experiments, it was demonstrated that it is also the carrier concentration range where the electron mobility peaks. Achieving such a low doping can be problematic as it is in the range of impurity dopants such as Carbon and Oxygen. A low doping and record mobility was achieved for vertical devices by MOCVD and applied to the OGFET and the CAVET. Devices were grown both, on sapphire and on bulk GaN and high breakdown voltages were achieved.Power devices require an elaborate growth and fabrication process, including regrowth on p-GaN doped by Magnesium and regrowth within trenches. Magnesium is known to diffuse into subsequent layers during regrowth, lowering device performance. A novel approach to circumvent this issue is presented, which can eliminate the need to remove the sample from the MOCVD chamber altogether. A low temperature GaN layer grown via flow modulation epitaxy successfully suppressed the Mg penetration at a rate of 5 nm/dec, the lowest ever by MOCVD, leading to the formation of an abrupt p-GaN:Mg/GaN junction.Regrowth within trenches was optimized for different applications. GaN was grown conformally within narrow trenches by exploring various growth conditions. A complete filling of trench was also achieved for a different set of applications. Finally, conformal regrowth of high composition, low temperature AlGaN was optimized for deep-recessed gate HEMTs to lower gate leakage. All of these were planar regrowths and no masks were used
Light-emitting plants: An Overview
No full textAuto luminescent plants are considered safe for humans and the environment. By inserting a special type of nanoparticles into the leaves of the watercress plant, MIT engineers have had the option to induce the plant to radiate a faint light for almost 3-4 hours. They believe more improvement so that plants in upcoming days sufficiently brilliant to light up the entire booth or room. In the nearing future, this kind of plant will play a major role in ornamental as well as economically. Shining plants are a case of how humanity can put forth a valiant effort to discover usefulness and esthetical magnificence in the encompassing scene
Properties and enhancement of Saccharum officinarum production in India
No full textSugar is probably the most established ware on the planet. It very well may be delivered from Saccharum officinarum, sugar beet, or different yields having sugar content. Saccharum officinarum is an inexhaustible eco-accommodating source as it replicates in patterns of short of what one year. In the examination, trees for paper creation, by and large, take 7 to 10 years to arrive at development, the double sugar (disaccharide) synthetic such normally contains glucose and fructose. Saccharum officinarum liquid is plentiful in natural endowment, for example, P, K, Ca, Fe, and Mg and nutrients, for example, nutrient retinoic acid or beta-carotene (plant version), thiamine, riboflavin, nicotinamide, pantothenic acid, pyridoxine, ascorbic acid, and alpha-tocopherol. Around 90-95 mL of Saccharum officinarum liquid holds 36-37 caloric power and 7-8 g of starches. Ethanol is can be utilized as a biofuel option in contrast to gas and is broadly utilized in vehicles in Brazil. It is a C4 plant, ready to change over up to one percent of episode sun-oriented power into renewable energy. The extra stringy build-up called bagasse (45-half dampness content) after juice extraction measure is usually combusted to create heat/power for in-plant use, it is one of the most effective photo-synthesizers in the plant kingdom. Saccharum officinarum leaves are normally covered by wax which is observed as a significant wellspring of different policosanols and D-003, and the industry of Saccharum officinarum not just produces sugar it will diminish joblessness and play a key role in the enhancement of Gross Domestic Product
