In this article, studies were conducted to evaluate the densification of W-Cu sintered compacts produced using two methods; liquid phase sintering (LPS) and combination of liquid phase sintering and liquid infiltration technique (LPS+LI) named Cu-melt infiltration (Cu-MI). Low concentration of nickel (1wt.%) was used…
Paper is constituted of natural fibers and represents a perfect example of structural multifunctional materials. Indeed, its fibrous structure is engineered to fit the different end use properties: both optical and mechanical properties are usually required. These requirements may lead to contradictory needs in terms…
The roughness and stripe of the carbon fiber surface is increased, what is in favour of the combination of fiber and resin, and also increases the active ingredient of fiber surface, by using the low temperature plasma on carbon fiber surface treatment. In this paper, we research the influence of CF/PES-C material ILS…
The dynamic response of fluid-filled hemispherical shell in mass impact is studied by experiment using DHR9401. Combining the time history of impact force with experimental observation of the deformation process, it can be seen that the dynamic response can be divided into four stages: the flattening around the impact…
This study reports a nanoporous anodic aluminum oxide (named np-AAO) template coated with Au nanocrown array on PET substrate for nanophotonic switching application (Fig.1). In this devices, the Au nanocrown array for nanophotonic switching are self-assembled on np-AAO/PET at its one end using batch processes. The adv…
ZnO:Ga films are attractive phosphors for a number of high energy physics and security applications because of their extremely fast temporal response (typically less than 1 ns). Significant efforts have been undertaken to study the dependence of luminescence properties of ZnO:Ga on dopant constituency and temperature.…
ncorporations of synthetic fiber into wood polyvinyl chloride composites (WPVC) were investigated for the effect of co-reinforcing fillers on wear behavior of WPVC materials. Physical and mechanical properties of the composites were also analyzed and discussed in association with wear behavior of co-reinforced WPVC. T…
In the present work, we employed low-energy ball milling in dry and wet conditions to synthesize Al-MWCNT composites with homogeneous distribution of reinforcing phases. Dry ball milling easily resulted in the collapse of MWCNTs as well as a cold welding of constituent particles. Wet milling, on the other hand, induce…
A fast oil-absorption resin with high pore level was developed by concentrated inverse emulsion polymerization. The oil absorption rate test displayed that only 30 min was needed for the resin to reach absorption saturation. The property was elucidated by the fully interconnected porous structure of the resins. Beside…
Although silver has long been used as an antimicrobial agent, it is not used often due to economical and environmental concerns. However, silver nanoparticles (AgNPs) have the same properties as elemental silver and can be synthesized on a considerably more economical level. The objective of this study was to synthesi…
The results from a series of height measurements of carbon nanopillars formed during residual hydrocarbon deposition on a pyrographite surface by a focused electron beam in an SEM are presented. The high initial velocity of the pillars’ vertical growth can be explained by the dominant role of surface diffusion in the…
Five kinds of unsupported MoS2hydrodesulfurization catalysts and the precursor of MoS2catalyst, nanosized MoO3, were synthesized by a novel hydrothermal reduction method. The influence of temperature, concentration of reactants and pH values on the growth morphology of MoS2was systematically investigated. The MoS2fibe…
Plant camouflage is conducted by use of planting and collecting plant and changing color of plant to conceal targets. It can be used to camouflage relatively big permanent fixed targets in peace time and also to camouflage relatively big permanent fixed targets in peace time and also to camouflage relatively small fix…
We report on the synthesis and photocatalytic activity of 10 wt% In2O3/BiOCl composite photocatalyst. The 10 wt% In2O3/BiOCl composite photocatalyst was synthesized by a simple chemical coprecipitation method at room temperature followed by thermal treatment at 400 °C for 2 h. During thermal treatment at 400 °C for 2…
In order to endue the underfill with reworkability, tertiary ester epoxy resin (TEER), bis[1-methyl-1-(6-methyl-7-oxa-bicyclo[4.1.0]hept-3-yl)-ethyl] isophthalate, was synthesized by the reactions of esterification and epoxidation. The structure was characterized by Fourier transform infrared With TEER as matrix, sili…
Due to the significant increase in the usage of silver nanoparticles in different industries, the need of knowing their potential hazard on humans is an appealing area of research. Workers who work in such fields are the most threatened by the harmful effects that may occur due to the consistent exposure to Ag-NPs dur…
The compound fabrics comprised of double layers of nonwovens and carbon fabrics were prepared by needle-punching and thermal bonding techniques. The thermal bonding and number of layers effect on thermal insulating and sound absorbing property have been discussed. The resulting compound fabrics have thermal conductivi…
Synthesis of titania (TiO 2 ) nanoparticles by sol-gel method and their calcination at different temperatures, viz 450 °C, 550 °C and 650 °C (defined as T450, T550 and T650) has been done. Structural analysis indicates that the T450 sample possesses anatase phase. The phase transformation to rutile starts occurring at…
A series of mesoporous TiO2 supports were synthesized by the sol-gel template method by using different surfactant and Au/TiO2 catalysts were prepared by the solution reduction method. The catalytic oxidation of CO was taken as the probe reaction for comparing the catalyst activity. Wide-angle XRD patterns and N2 adso…
The electron energy loss spectroscopy (EELS) technique was applied to investigate the local variation in the phase of barium titanate (BaTiO₃) ceramics. It was found that the fine structure of the titanium L₂,₃ edge and their satellite peaks were sensitively varied with the tetragonal-cubic phase transition. The peak…
