Ferroelectric Pb(Zr0.52Ti0.48)O3 (PZT) thin films rapidly crystallized by microwave irradiation were compared with those obtained by conventional furnace process. The PZT films under microwave irradiation at 650 °C for 60 s were crystallized well in to the perovskite phase, and showed butter electrical properties than…
Replica exchange molecular dynamics simulations of coarse-grained poly- methylmethacrylate(PMMA) chains are performed. The coarse-grained force field for PMMA is developed based on the Iterative Boltzmann Inversion method. The proposed coarse-grained model, successfully reproduced the properties of the polymer melts (…
Multi-walled carbon nanotubes (MWCNTs) were synthesized using catalytic chemical vapor deposition (CVD) method. Oxygen plasma treatment was applied to modify surface state of the CNTs synthesized for improvement of field emission performance. Surface state of the plasma treated CNTs was studied by X-ray photoelectron…
In this paper, we studied a p-type reflector based on indium tin oxide (ITO) for vertical-type ultraviolet light-emitting diodes (UV LEDs). We investigated the reflectance properties with different deposition methods. An ITO layer with a thickness of 50 nm was deposited by two different methods, sputtering and e-beam…
The homogeneous mixture of N,N'-bis(2-hydroxyethyl)oxamide (BHEOD) and boric acid reacted with an excess of ethylene carbonate (EC). Obtained hydroxyethyl derivatives of oxamide (OD) modified with boric acid are characterized by high thermal stability and exhibit physical properties of typical polyols used in the prep…
Flower-like ZnO nanostructures have been synthesized using zinc nitrate hexahydrate and hexamethylenetetramine (HMT) by a low-temperature hydrothermal technique. The prepared ZnO nanostructures exhibit hexagonal wurtzite structure, well-defined flower-like morphology, and a strong blue emission photoluminescence. Flow…
Iron phosphate was prepared from iron nitrate and phosphoric acid with a surfactant, pentaethylene glycol mono dodecyl ether. The chemical composition of the obtained samples was estimated from ICP and XRD measurements. Particle shape and size distribution were observed by SEM images and laser diffraction / scattering…
Features of a defective microstructure and the mechanical properties of titanium nitride coatings having different copper content are investigated by means of transmission electron microscopy, X-ray structural analysis, microhardness measurement, and scratch tests. It is shown that, under a relatively low deposition t…
The thermal stability and glass-forming ability (GFA) of Zr70Ni30−xAlx (x = 5 − 19) metallic alloys were investigated. Alloy with x = 8 has the largest critical diameter (dc) of 2 mm in the alloy series, which possesses the largest supercooled liquid region, Trg and γ value, simultaneously. Further addition of 2 − 4 a…
The objective of this paper is to give an insight on the aspects considered reduce the power demand in the electrical system design and the problems faced in implementing the same during the construction of commercial and residential buildings. Energy efficient light fixtures and motors which comply with ECBC standard…
The effects of temperature on carbon nanotubes (CNTs) by thermal chemical vapor deposition (TCVD) method were systematically studied. Natural hydrocarbon source; palm oil was used as precursor and argon as carrier gas. Palm oil vaporized optimally at 450oC in ambient pressure. The synthesis temperature start at 650°C…
In this work, a rolling schedule has been developed, which allows the scrapped S60 railway rail to be used for further processing into semi-finished or finished products. The main purpose of the investigations was to develop the shape and dimensions the rolling grooves and to select the strains in various passes in th…
PubChem is an open repository for molecular structures, their properties and biological activities [1]. The number of deposited structures has been steadily increasing since its creation in 2004. Today, it contains more than 92 million substances (PubChem Substance) with 32 million unique small molecules (PubChem Comp…
It is my pleasure to welcome you to the 29th Semiconductor Thermal Measurement, Modeling, and Management Symposium in San Jose, California. Our mission statement declares that “SEMI-THERM is to provide an annual forum for the exchange of latest technical developments in thermal management of electronic devices, compon…

ZnO, as an important semiconducting material, has a wide range of applications in optics, optoelectronics, sensors, actuators, energy, biomedical sciences and spintronics [1]. ZnO exhibit the most splendid and abundant configurations of nanostructures that one material can form. ZnO is one of the few dominant nanomate…
We make clusters of atoms of the size of less than 1 nanometer by using the density functional theory and from that we obtain the bond lengths corresponding to the minimum energy configuration. We are able to optimize large clusters of atoms and find the vibrational frequencies for each cluster. This calculation provi…
In this work, the electrical properties of carbon nanotubes were deposited on silicon substrate at different temperatures studied. CNTs were deposited on silicon at temperature 700 to 850 0C by using double-furnace thermal chemical vapor deposition technique. Carbon nanotubes with diameters of 20 to 30 nm were success…
Nanosphere lithography is an inexpensive, simple, high-throughput nanofabrication process. NSL can be done in different ways, such as drop coating, spin coating or by means of tilted evaporation. Nitride-based light-emitting diodes (LEDs) are applied in different places, such as liquid crystal displays and traffic sig…
Numerical simulations for tests of thin metal plate against explosion were performed by using models with and without taking into account shock wave around-flow. The results show that the center deflections of plates from numerical simulations are in good agreement with those from experiments, and that the shock wave…
