Abstract:
Pyrolysis of bitumen has been performed without water, in supercritical water and over cerium oxide catalyst to further understand the upgrading mechanism of bitumen at 723 K. The asphaltene conversion was promoted in catalytic cracking compared with hydrothermal and thermal cracking, respectively. Based on the results, the lightest oil was extracted in catalytic cracking and the concentration of asphaltene in rich oil phase was decreased. On the other hand, physical effect of water can change phase equilibrium which affects the reforming reactions. Another keen aspect is of hydrogen transfer from water to heavy oils in the presence of catalyst. In this research, CeO2 was employed as catalyst and the possibility of oxidative decomposition and hydrogenation of bitumen in supercritical water was studied. A redox reaction between the water, bitumen, and catalyst was occurred for the production of hydrogen and oxygen. It was found that the oxygen storage capacity (OSC) of the cerium oxide nanoparticles with cubic {100} facets was nearly 3.4 times higher than that of the cerium oxide nanoparticles with octahedral {111} facets. Therefore, heavy oil fractions of bitumen were cracked in a batch-type reactor at 723 K in order to produce as much light oil as possible, and the effect of water density, the catalyst loading and reaction conditions on the conversion rate and coke formation were investigated. As a result, it was demonstrated that it is possible to obtain a high conversion rate by employing cubic CeO2 nanocatalyst that shows high exposed surface area and large OSC.

Abstract:
Drinking water plays an important role in the health and hygiene of a human. Every country maintains different standards. From ancient times in India, drinking water is stored in silver vessels because it kills germs and controls the germs multiplication. Silver has the characteristic of being antimicrobial and it is used for plating the vessels. Silver has least toxicity to animal cells. Thus, it makes the water sterile. Pulse plating is used because it produces nanograin when plated. Thus nanoplating using silver metal is done on storage vessels. This technique can ideally be used in hospitals to serve the patients. When the storage medium is made small in size, can ideally be used in homes for improvising the health of the people in whole. There is an increase in adhesion of the plated material on to the substrate, increase in hardness, high smoothness and highly antimicrobial activity is acheived through nanoplating. When any material is coated with nanograin, obviously it has the property of using very low raw material absorption rather than the conventional DC plating with higher order grain size.

Abstract:
The present study involves the applicability of cobalt ferrite and manganese ferrite nanoparticles as an adsorbent for the removal of lead, zinc and Congo red dye from the aqueous solution. The nanoparticles were synthesized by co-precipitation method by incorporating chlorides and sulphates of respective metal ions with sodium hydroxide as pH stabilizer. The point of zero charge for cobalt ferrite and manganese ferrite nanoparticles were estimated by solid addition method and were found to be 9.3 and 6.1 respectively. The synthesized nanoparticles was characterized using X-Ray diffraction, scanning electron microscope with EDAX, transmission electron microscope, vibrating sample magnetometer, Fourier transform infrared spectroscopy and surface area analyzer. X-Ray diffraction and transmission electron microscope studies confirm the formation of single phase cobalt ferrite nanoparticle by showing more crystalline in its alkaline condition. From the X-ray diffraction studies, the size of the cobalt ferrite nanoparticles was found to be in the range 52.87 nm to 60.18 nm while for manganese ferrite nanoparticles the size was found to be in the range 15.82 nm to 17.35 nm. From the transmission electron microscope studies, the size of cobalt ferrite nanoparticles was found to be in the ranges of 16-49 nm and for manganese ferrite nanoparticles, the size was observed to be in the range of 40-200 nm for manganese ferrite nanoparticles respectively. The scanning electron microscope studies reveal that the structure of the nanoparticles were agglomerated and the particles were circular and elongated in shape in the case of cobalt ferrite and mangansese ferrite nanoparticle. VSM studies exhibited the magnetic properties of both the nanomaterials with the help of a soft magnet which indicated the formation of lean loop. FTIR studies reveal the formation of cobalt ferrite and manganese ferrite nanoparticles indicating the presence of relevant functional groups. The adsorption process control parameters were optimised and adsorptive capacity of nanomaterials were predicted through kinetic and isotherm modelling.

Abstract:
Leachate is waste solution as human activity product, it should be managed in order to minimize its negative impacts to the environment and human health. Environmental pollution will also take place due to waste which contains hazardous organic and an organic substances, such as used battery accumulates and broken TL bulbs. Production of those goods uses Plublum (Pb) in its process, so that the Pb will be carried later by the leachate flow to the environment. This work was an experiment 0.2% of Kepok (Musa ascuminata balbisiana colla) banana’s peels nanoparticle is added in leachate with three concentration variation was about 2.5%, 4.0% and 6.3%. The absorbance and size of Kepok (Musa ascuminata balbisiana colla) banana’s peels nanoparticle were determined by Spectrophotometer UV-Vis and Scanning Electron Microscope (SEM). The concentrations of Pb and Cr after treatment were determined by Atomic Absorption Spectrophotometry (AAS). The result showed that concentration of Pb and Cr in leachate decreased after it was treated using experiment Kepok (Musa ascuminata balbisiana colla) banana’s peels nanoparticle. The significant reduction of Pb and Cr concentration is at 6.3% of leachate concentration. Therefore, it can be concluded that treatment using Kepok (Musa ascuminata balbisiana colla) banana’s peels nanoparticle can be applied to reduce concentration of Pb and Cr in a leachate.

Abstract:
The current research scenario for alternative energy sources is primarily focused on the reduction of dependency on fossil fuels, so that the harmful effects of greenhouse gases can be minimized. Thermoelectricity can contribute to this area of research by waste heat utilization for electric power generation and thus the reduction in CO2 emission. The efficiency of a thermoelectric material is defined by a dimensionless parameter thermoelectric figure of merit ZT=S2ï³T/ï«,where, T, ï³ and ï« are the absolute temperature, electrical conductivity and thermal conductivity, respectively, and S is the See-beck coefficient or thermo-power, which is defined as ï„V/ï„T, i.e., the voltage that develops across a sample with a temperature gradient of 1 K. High ZT requires an unusual type of material: a good electrical conductor with high thermo-power, but low thermal conductivity, i.e. it must scatter phonons (to minimize lattice contribution to thermal conductivity) without troubling the transport of charge carriers, i.e., ceramic and metallic behaviors are combined to a single material system. Due to the strong interdependency of the parameters S, ï³ and ï«, the reduction of thermal conductivity without deteriorating electrical conductivity is a challenging task. Structuring material systems to the nano-dimension scale can facilitate the tailoring of phononic transport independently or quasi –independently of electronic transport and thus the manifold enhancement of ZT. The focus of the present talk is to discuss the different approaches for tailoring electronic and phononic properties in nano-structured materials at different length-scales leading to the enhancement of ZT.

Abstract:
My group's research is aimed at understanding some of the basic principles of smart microfluidics and 1D/2D material growth, solving problems in the implementation of these materials. I will present two different topics. First topic is our development of the low pressure chemical vapor deposition (LPCVD) growth of 1D and 2D materials. We grow large-grain single crystalline or large-scale polycrystalline monolayers of MoS2, MoSe2, WSe2 and WS2 along with other transition metal dichalcogenides (TMDs). Our unique growth method permits the growth of TMDs on the ‘contacted’ areas only, enabling the chip-scale fabrication of heterostructures in arbitrary shapes without lithography. We also demonstrate an approach toward controlled CNT growth atop graphene substrates, where the reaction equilibrium between the source hydrocarbon decomposition and carbon saturation into/precipitation from the catalyst nanoparticles shifts toward CNT growth, rather than graphene consumption. Second, we demonstrate a novel in situ control of the droplet pinning on the polymer surface, enabling the control of droplet adhesion from strongly pinned to extremely slippery (and vice versa). The adhesion of organic droplets on the surfaces dramatically switches in situ (i.e., without the removal of liquid droplets), presenting a great potential for in situ manipulation and control of liquid droplets for various applications including lab-on-chip technologies, oil separation, and water treatment.

Abstract:
Outstanding carrier transport properties of III-V compound semiconductors have shown excellent potential for high frequency characteristics. Among them, III-V HEMTs on various material systems like InGaAs/InAlAs, InAs/InP have emerged promising for millimeter wave and terahertz applications. Many previous reports of record high frequency characteristics have shown InGaAs/InAlAs HEMTs with very high cut off frequency (ft) and maximum oscillation frequency (fmax). With increase in Indium concentration higher electron mobility can be achieved which can lead to higher operating frequency. Among them, InAs HEMTs have shown high frequency record of 710 GHz for 60 nm gate length. These HEMT structures can be fabricated for high frequency applications using Molecular Beam Epitaxy (MBE) and Metal Organic Chemical Vapor Deposition (MOCVD) techniques. Small gate length devices have shown excellent RF performances over past two decades. Besides, due to high electron mobility, saturation velocity and large conduction band offset in InAs, InAs-channel HEMTs are also promising for high speed and low power applications. InAs pseudomorphic HEMTs on InP substrate have been reported to have less short channel effects (SCE) through cap recess engineering and demonstrated low gate delay time when biased at 0.5V. In conclusion, InAs devices are promising for high frequency applications upto sub terahertz range and high speed low power logic application for post Si CMOS application. The outstanding performances of the device will be presented in this talk.
