Packaging microelectromechanical systems (MEMS) frequently makes up about Eighty Pct of both the price and also the failures of the devices. For biological MEMS with microfluidic channels, packaging demands reliable fluid and electrical connections. This report explains different techniques for improving the
Nowadays perpendicular ferromagnetic nanowires have drawn substantial interest because of the potential use in many areas of advanced nanotechnology, particularly high-density recording media. A great recording medium in this respect includes a densely organized assembly of nanometer-scale ferromagnets with high magnetization and
Ceramic attributes like biocompatibility and inertness have secured their utilization in biomedical prosthetics. The brittle character of ceramics governs their application in any design and fabrication approach. Current all-ceramic dental crowns have a recorded failing rate of around 3% annually. A study
Multiferroic materials and systems that concurrently display ferroelectricity and magnetism have drawn great attention due to their amazing physical properties as well as their potential applications that use coupling of magnetism and ferroelectricity. The purpose of this report was to study multiferroic
This report is on FeGa Alloys. Microstructural analysis of rapid-solidified (melt-spun) FeGa alloys with 17.3at.%Ga and bulk alloys with 12-20at.%Ga using transmission electron microscope was carried out. Dark field and high resolution image analysis show all the samples are inhomogeneous with fine texture of 5-10nm.
The use of e-beam based plasma as a source for plasma-polymer interactions was investigated employing two advanced photoresists that differed significantly in polymer structure. The influence of Ar+ bombardment energy, chemically-assisted etching using fluorine, and the effects of the presence of a thin fluorocarbon..
In this study, we successfully fabricated dense, uniform, vertically aligned ZnO NWs on top of DLC films. The NWs’ length, diameter and separation distance were controllable by fine tuning the growth parameters and changing the DLC film deposition temperature… Contents Chapter 1.
NiMnGa alloys have attracted extensive attention because their ferromagnetic characteristic provides an additional degree of freedom to control both the shape memory effect and the multi-stage phase transformations in this Heusler system. Technically, along with the large magnetic-field-induced strains… Contents 1 The
The main theme of this work is the application of various surface analysis techniques, including ultraviolet photoelectron spectroscopy (UPS), X-ray photoelectron spectroscopy (XPS), Auger electron spectroscopy (AES) and atomic force microscopy (AFM), to the study of several issues related to the operating
This work presents the recent progress in research of synthesis and doping of cubic boron nitride (cBN) films, prepared by chemical and physical vapor deposition (CVD and PVD) methods. Cubic boron nitride (cBN) is a synthetic material which does not exist in
