Nano LaAlO3 & Simulation Comparisons of High K ...

The continued scaling of CMOS transistor requires replacement of the conventional silica gate oxide (SiO2) with a higher dielectric constant (K) gate dielectric to minimize the leakage current and to maintain a high capacitance especially at nano level to escape Quantum Mechanical Tunneling. Among many contenders, La2O3 is believed to be the suitable successor but the lanthanide oxides are known to be hygroscopic, which can affect their dielectric quality. Hence, we present a work on mixing the lanthanum oxide (or lanthana) with a less hygroscopic oxide such as Al2O3 to stabilize the insulator layer. Lanthanum Aluminate (LaAlO3) is much less susceptible to moisture. It also combines the advantages of the high dielectric constant of La2O3 and the chemical and thermal stability of Al2O3. Synthesis of Lanthanum Aluminate nano particles is done by Gelation-Precipitation method and are characterized by XRD, PSA, UV-Vis, TG/DTA, SEM, TEM and LCR-meter. The SiO2, La2O3, LaAlO3 are simulated, the reduction in leakage current of MOSFET using nano Silica, nano Lanthana and nano Lanthanum Aluminate insulator is studied using Quantum Wise-Virtual Nano Lab and Nextnano software tools.

Magnetic nanostructures have attracted increasing attention because of their potential applications in high-density data storage and in sensor technology. An understanding of the fundamental physical properties of these nanostructures is of interest in the study of atomic structures and micromagnetism. This book presents a study on the growth of nickel nanowires in commercially available templates. Electrodeposition was used through the pores of a template to produce nanowire matrices. Dependence of the nanowire growth rate, quality of deposit, growth uniformity, crystal orientations and other physical properties of the nanowire network were studied using various process parameters. Structural properties of the nanowire were characterised using AFM, SEM, EDX and TEM. Magnetic properties of the nanowires were studied using a VSM and MFM. Using OOMMF software magnetic behaviour of the nanowires was simulated and compared with the experimental coercivity values and magnetisation behaviour. The target audience of this book is the postgraduate students and the researchers who would like to study the fabrication and characterisation of magnetic nanowires.

This project is an approach towards the synthesis and characterization of liquid Gallium filled Indium Oxide nanothermometer by using resistive chemical vapor deposition technique. All the measurements and microscopical studies has been presented by using the concepts of different microscopies like XRD/SEM/EDX/HRTEM and related sample characterization software like Pcpdfwin (XRD-Analysis), Origin (Plotting graphs), Image Tool (SEM Images Analysis) and Digital Micrograph (TEM/HRTEM Images Analysis). The growth methods such as resistive heating chemical vapor deposition (RH-CVD) and growth mechanisms such as vapor-liquid-solid (VLS) and vapor solid (VS) of growing nanotubular structures have been discussed in this report. The HRTEM-EDX measurement along the radial direction of an Indium Oxide nanotubular structure explore the in depth knowledge of the flow of liquid Gallium. These similar observations have not been reported by other authors. The synthesis of metal filled Oxide nanotubular structures may have potential applications in future nanofluid devices. It could be ideal for the semiconductor industry and bio medical fields.

Loratadine is a non sedative anti-histaminic drug. Its major use is in control of congestion, sneezing, runny nose and itching that a patient suffers with an allergic attack or an infection. It has poor solubility in water. Therefore, the solubility and drug release were enhanced using the solid dispersion technique and fast dissolving tablet were formulated. Solid dispersion prepared using Poloxamer 407, PEG 6000 and urea. The solid dispersion were evaluated for saturation solubility, drug content and in vitro dissolution study and it was characterized using FT-IR, X-RD, SEM and DSC study. The fast dissolving tablets of loratadine was formulated using crospovidone and crosscarmelose sodium by direct compression method. The tablets were evaluated for thickness, hardness, weight variation, friability, disintegration time and % in vitro drug release. A 32 factorial design was used to study the effect of Loratadine: Poloxamer 407 and crospovidone on disintegration time and % in vitro drug release. The responses were analyzed using ANOVA. The obtained model was validated & optimized formulation was prepared as suggested by the software.

Heat and Mass Transfer in Urea Prilling Process

Urea prills are produced in the prilling tower, where a cooling-solidification-cooling process of the prills takes place. The ambient air is used as the cooling stream for this process. A case study of the urea prilling process is chosen due to in hot/humid days, the temperature of the product at the bottom of the prilling tower is hot and cannot be packed directly. In addition, the urea prills form lumps and cakes with each other on the scrubber at the bottom of the prilling tower that affects the quality of the product. A mathematical model based on the particle kinematics,and, heat and mass transfer between the urea prills and the cooling air is developed. This is followed by using a numerical technique with an explicit scheme to solve the model. The model numerical results are validated with Scanning Electronic Microscope (SEM) observation of urea particles. Moreover,to investigate the effect of the urea prilling tower configuration parameters on the above urea product problems, the hydrodynamic of air flow inside the tower is analyzed using Computational Fluid Dynamics (CFD) simulation software.

The output of this research is framework that informs the adoption of Software as a Service (SaaS) for Small and middle-sized businesses (SMEs). Recent research has shown that there are significant advantages of SaaS when adopted by SMEs. The author investigated SMEs in different sectors on a weighting proposal. This target was 87% in excess of the required minimum of 200 respondents as required by Structural Equation Modeling (SEM) which was done using SPSS AMOS focused on modeling, trimming and best fit. However 293 respondents were obtained, which was significantly above the minimum requirement. The findings indicated that the factors that significantly influence the adoption of SaaS by SMEs include: awareness, trust, prior IT experience, relative advantage, triability, ICT knowledge and skills, top level management support and complexity. The researcher was able to recommend firstly, that evaluation of the market is critical for SaaS deployment and finally, that application developers, technological consultants, software vendors, and policy makers that intend to adopt SaaS should consider the extended TOE model developed from this research.

With the development of technology and industries, newer materials such as Tungsten, Molybdenum etc. and various other Super Alloys and Ceramics have been developed which are being widely used in nuclear engineering, aerospace and various other industries because of their hardness, heat resistance qualities and high strength to weight ratio. Machining of these hard materials is very difficult by conventional machining processes. Therefore non-conventional machining processes have been developed for the machining of such type of materials. The Objective of this work is mainly to study the effect of various input parameters like Electrode material, Discharge Current, Gap Voltage, Pulse-On Time, Pulse-Off Time on the various output parameters like MRR, TWR and Surface roughness. In this study, these output parameters are studied by using the Taguchi's Design of Experiments through Minitab software. Using this software, Means and S/N ratios for all the output parameters were calculated. Micro structure was also observed using SEM machine.
