In this study, CdTe thin films were grown by RF magnetron sputtering with substrate bias at floating potential and 0, -10, -20, -30, -40, -50, -100 V. The applied substrate biases affect film morphology, grain size and lattice structure. For films grown with substrate bias at floating potential, 0, -10, -20 V, no in-p…
Characterization of the rate of nucleation of crystals from solution continues to be of interest, both for investigations into fundamental molecular phenomena as well as for applications in the pharmaceuticals, biotechnology, and fine chemicals industries. Substantial experimental evidence indicates that nucleation in…
Fundamental obstacles to the modeling and simulation of magnetic components are lack of high-fidelity models and exhaustive computational burden. Physics-based magnetic components have been recently proposed that accurately present the higher-order dynamics (e.g., eddy current). However, introduction of hundreds to th…
Effect of the partial oxygen isotope substitution on (Pr1-yEuy)0.7Ca0.3CoO3 cobaltites was studied in detail for the crossover region (0.12<у<0.26) of the phase diagram. We prepared a series of the cobaltite samples with the different degrees of enrichment by the heavy oxygen isotope 18O, namely, containing 90%, 67%,…
Purpose: This study investigated if the dose-response of EBT2 film can be modeled as a bimolecular reaction of the monomers that composes the active layer of the EBT2 film. The LET dependence of EBT2 films was explored using the models developed in this study. Methods: To build a dose-response curve a set of films was…
In this study, Pseudomonas aeruginosa was isolated from pus samples and was characterized using pheno- typic and genotypic methods. It was confirmed to be an ESBL producer through Double Disc Synergy assay. This was then used to produce silver nanoparticles using two different concentrations of silver nitrae over a pe…
The cold ramming paste for aluminum electrolysis has been studied using electrically calcined anthracite as aggregate, medium temperature pitch and anthracene oil as binder, metallic silicon powder as additive in the paper. The effects of addition of silicon on volume density, compressive strength, electrical resistiv…
Abstract Hochauflösungs‐TEM/STEM spektroskopiert und bildet Strukturen atomar aufgelöst ab. Mit einer Mikrofluid‐Probenkammer eignet sich das Elektronenmikroskop auch für In‐situ‐Untersuchungen zu lebens‐ und materialwissenschaftlichen Fragen.
The phase transitions and critical phenomena in three-dimensional (3D) site-diluted 3-and 4-state Potts models is investigated by Monte-Carlo method based on the highly efficient Wolff algorithm. The systems with linear sizesL=20-44 at spin concentrationsp=1.00, 0.95, 0.90, 0.80, 0.70, 0.65 are explored. The second-or…
Abstract Under a white ambient light illumination and without bias, the color‐cathode organic light emitting device (OLED) shows the various reflection colors to display the information by utilizing the internal interference cavity inside rear cathode. In this report, we employed a high conductivity metal‐organic mate…
CIGS thin films were prepared by selenization of Cu-In-Ga-Se precursors, as a new method, the effects of selenization temperature on the properties of CIGS thin films were studied. First, Cu-In-Ga-Se precursors were deposited onto Mo-coated soda lime glass by evaporation and sputtering method. Then, precursors were se…
It is known that diamond is not suitable for cutting of ferrous metals, ascribed to serious tool wear occurred in machining process. For the sake of studying the tool wear mechanism further, this paper presents thermal analysis method to discuss the chemical transformation of diamond with Fe catalysis. Raman scatterin…
The hot deformation behavior of a high strength low alloy (HSLA) steel for construction application under hot working conditions in the temperature range of 900 to 1100 and strain rate range from 0.1 to 10 s-1 has been studied by performing a series of hot compression tests. The dynamic materials model has been employ…
