NiO thin films have compounded by pulsed laser deposition on glass and silicon (111) substrates, employing Q-switching Nd:YAG laser. Structure, grain size and optical properties have analyzed by using FTIR, AFM and UV-VIS spectroscopy. FTIR spectra conformed of NiO bonding. AFM images show the particle size about ~66n…
The beltline region of the reactor pressure vessel (RPV) is subject to an extreme radiation, temperature, and pressure environment over several decades of operation; therefore it is necessary to understand the mechanisms through which radiation damage occurs and how it affects the mechanical and chemical properties of…
We perform molecular beam epitaxy growth and scanning tunneling microscopy study of copper diselenide (CuSe 2 ) films on SrTiO 3 (001). Using a Se-rich condition, the single-phase pyrite CuSe 2 grows in the Stranski—Krastanov (layer-plus-island) mode with a preferential orientation of (111). Our careful inspection of…
The impact of Li+dopant-ions in fluorine-containing electrolytes on electrodeposited manganese (IV) oxide material was under investigation in this paper. The dependence of phase composition of this material at Li+-concentration range in the electrolyte below the stoichiometric content of lithium in hollandite A2Mn8O16…
We report pure green core‐multishell quantum dots synthesized by modified tri‐n‐octylphosphine‐assisted SILAR method. In this low‐cost, high‐throughput procedure, we coupled with tri‐n‐octylphosphine‐assisted extraction process to obtain the satisfactory results. The spectrally narrow emission (26 nm), high luminescen…
Free‐form, or unbreakable displays are attractive from a consumer point of view but are difficult to manufacture. We have developed state‐of‐the‐art liquid crystal mixtures that can create polymer wall structures within the display. This utilizes existing manufacturing techniques and enables flexible substrate based l…
Abstract We report the first semisynthesis of the natural insect antifeedant azedarachol. The synthesis features the employment of pregnanetriol, a degradative product of the resource natural product tigogenin, as the starting material, the symbiotic reaction involving the mutually‐promoting elimination of toluene‐sul…
Micro energy storage devices have drawn increasing attention due to the importance of power supply in miniaturized multi-functional systems. This paper reviews the recent progress in micro energy storage devices, particularly the micro supercapacitors, including the design issues of device architectures, electrode mat…
The present work focuses on the microstructure of annealed damascene Cu interconnects with different trench aspect ratio and line spacing. The X-ray diffraction (XRD) and electron backscatter diffraction (EBSD) measurements are conducted on the surface of Cu interconnects after removal of the SiN layer. The experiment…
Based on the Boltzmann transport equation in the MRT approximation, we present a theory to investigate low-field carrier transport in dual-gated silicene FETs by taking into account screened charged impurity scattering, which is the most likely scattering mechanism limiting the conductivity. Static RPA dielectric scre…
The overall cable insulation condition can be monitored continuously by the implementation of an on-line partial discharge (PD-OL) monitoring system. It can both detect and locate the sources of PDs and also assess the insulation condition by using past data. The utilization of an accurate electromagnetic transient mo…
There is a high demand in the textile industries for environment friendly processes with minimum wastewater generation. In addition, the reduction of oil reservoirs has led to an increased interest in production of biodegradable polymers from renewable natural recourses like plants. Poly-lactic-acid (PLA) , the fist s…
Modified by the pretreated model with collagen under the crosslinking effect of glutaraldehyde, the moisture absorption of modified samples increased by 26.34% and 42.6%. The test results of SEM, AFM and DSC show that there was coating on the fibers modified with collagen, and the relative average roughness of the mod…
Neodymium doped sodium bismuth silicate glasses were prepared by the melt quench technique. Optical absorption spectra of the Nd3+ion in the present glassy systems were recorded in the UV-Vis-NIR region. Taylor series expansion method was adopted for theoretical evaluation of various crystal field parameters such as t…
High quality pure color quantum dots (QDs) were synthesized and employed to fabricate QDs light converting film (QDF). The advanced QDs film (AQDF) with embedding of nano‐TiO 2 particles demonstrated excellent luminescence with 66.48% of light power conversion efficiency (CE), which is higher than that of normal QDF (…
The paper continues the discussion of original studies on magnetic structural-phase analysis. Part II deals with the application of structure-insensitive magnetic characteristics to qualitative and quantitative phase analysis. Phase analysis procedures are discussed. Applications of nondestructive testing devices desi…
The ternary chalcogenides AgInSe2 and AgInTe2 were studied by X-ray powder diffraction structure refinement using the Rietveld method.
