According to the availability of bagasse waste and increasing environmental concern, this research is focused on the preparation of polylactic acid (PLA)/bagasse carboxymethyl cellulose (CMCB) composite in order to improve the thermal and mechanical properties of PLA/CMCB film. PLA were mixed with CMCB at different ra…
We have synthesized high-quality BiMnO3 thin films on Nb-doped SrTiO3 substrates with (100), (110), and (111) orientations. All the films with different orientations undergo ferromagnetic transitions at approximately the same temperature (∼105 K) as bulk BiMnO3 does. The magnetic easy direction was also found to be th…
The useful life of concrete is associated with the penetrative ability of aggressive agents on their structures. Structural parameters such as porosity, pore distribution and connectivity have great influence on the properties of mass transport in porous solids. In the present study, the effect of varying the workabil…
GaN-based UV Schottky-type (ST) LEDs were fabricated using GaN layers grown by molecular beam epitaxy (MBE). Red, green, and blue (RGB) pixels were fabricated using the UV-LEDs and RGB phosphors. Surface modification led to the reduction in reverse-bias leakage current and improved forward-bias characteristics. It was…
The new method of the reliability calculation of buildings and structures’ earth foundations based on limited statistical information on controlled parameters in the operation stage is considered. The reliability is calculated by criterion of foundation deformations (settlement) in the presence of load eccentricity of…
In this paper, a type of high-deposition-rate, low-dilution-rate and wide-welding-bead flux-cored strip which is easy to realize automatic surfacing was designed. Considering the working condition of high temperature and abrasive wear in the iron and steel industry, a kind of high-chromium iron surfacing flux-cored st…
Carbon-based nanostructures have been the center of intense research and development for more than two decades now. Of these materials, graphene, a two-dimensional (2D) layered material system, has had a significant impact on science and technology in recent years after it was experimentally isolated in single layers…
Reagent grade chemicals were used to explore glass formation ability and allocate the glass forming area for the glass system SiO2-P2O5-Al2O3-MgO-Na2O. FT-IR, DTA, DSC and TMA techniques were employed to characterize the obtained glasses. The multicomponent, mixed network glasses, in which AlPO4 tetrahedral units are…
Fiber woven membranes were prepared with konjac glucomannan (KGM) and sodium hyaluronate (SH). Glycerol was added as plasticizer and lactic acid as modifier. After treatment with microwave,wet spinning method and the programmable 2D mobile platform were used to prepare the KGM/SH fiber woven membranes. The in vitro de…
We synthesized nanoparticles of the perovskite manganite DyMnO 3 in pores of mesoporous silica SBA-15 and investigated their magnetic properties. X-ray diffraction patterns of the nanoparticles indicated successful synthesis of the DyMnO 3 nanoparticles with a particle size of about 10 nm in the pores of SBA-15. The t…
A core-hollow shell composite composed of a nickel (Ni) nanoparticle core encapsulated in a hollow silica shell (Ni@SiO2) was prepared by using a nanocrystalline salt of nickel tris-hydrazine complex, which acted as not only a nickel source but also a solid template to produce the core-hollow shell structure. Structur…
Results of the quantum-chemical PM3 and experimental spectrophotometric studies of the stepwise protonation of tetrakis[3(4)-chlorophthalocyaninato]copper(II) are presented. The number, structure, and energy characteristics of consecutively protonated isolated molecules of the substituted complexes have been determine…
Surface Enhanced Raman Scattering (SERS), that occurs by exciting plasmon resonances in metal structures, provides high-sensitivity detection with detailed molecular information. Here we describe the combination of SERS and nanofluidics for the molecular detection inside a plasmonic nanoslit across a thin, metal-coate…
The influence of Cr on corrosion behavior of P110 steel was studied in the simulated CO2 environment. The result demonstrated that the Cr cant change the effect of temperature on P110 steel. The corrosion rates of the two kinds of materials reached the peak at 90°C. The temperature has dual effects on corrosion, which…
High quality VO2 films have been successfully deposited by pulsed magnetron sputtering. In the preparation of vanadium dioxide films, the stoichiometry, structure and orientation of vanadium dioxide can be influenced by the process parameters. In this study, sputtering power and oxygen partial and substrate temperatur…
Extended abstract of a paper presented at Microscopy and Microanalysis 2013 in Indianapolis, Indiana, USA, August 4 – August 8, 2013.
Fatigue properties of the newly-formed and served canopy PMMA, which was applied in a certain airplane, were studied by experimental method. In order to gain the fatigue strength in the designated life, experiments based on up and down method had been conducted. The S-N curves of the PMMA were acquired based on three-…
The trend towards portability of electronic products expands the application of rigid-flex board, which has become one of the hot spots in PCB industry. Along with the improvement of assembly technology, the improving design of rigid-flex board appears. High Density Interconnection (HDI) is one of the design direction…
Solid solution crystals (LuxGd1-x)2SiO5 single doped with Sm 3+ and Dy 3+ were grown by the Czochralski method. Segregation coecients Lu/Gd, melting temperatures and structures of solid solution crystals were determined for 0.15 x 0.8. It was found that for x 0.17 the crystals belong to the monoclinic system within a…
Self-propagating reaction is presented as a new heat source for the joining of MEMS and high power devices. However, due to the complex thermal process of self-propagating reaction, the temperature in solder or multilayer foil during the joining process is difficult or even impossible to measure and control. Therefore…
