In order to ensure the quality of charge, honeycomb structure explosives was designed to resolve the current issue about the backward method of charge; Explosives with structure of honeycomb and double sided explosive cladding are used to increase of energy efficiency of explosives and save the amount of explosives. I…
Wetting-transparent graphene coatings on a hydrophobic surface deliver exceptional anti-corrosion and wetting stability to the underlying metal surface. These graphene-coated surfaces enable improved droplet mobility, which is required in a variety of promising applications, such as condensation surfaces for water har…
The effect of vinylene carbonate (VC) as electrolyte additive on the electrochemical performances of the Si/disordered carbon (Si/DC) composite electrode / liquid electrolyte interface was studied in this paper. The electrochemical performances of Si/disordered carbon (Si/DC) composite electrode were systematically in…

The hydrodynamic cavitation degradation of chitosan with NaNO2enhancement was investigated. The effects of NaNO2dosage, temperature, inlet pressure, PH value, the concentration of the chitosan were been discussed. It was found that the hydrodynamic cavitation degradation of the chitosan can be largely enhanced by addi…
A facile self-assembly/solvothermal strategy is developed by J. Shi, J. Gong, Y. Li, and co-workers on page 4947, who synthesize monodisperse, large-pore silica nanospheres with both ordered and interconnected open mesopore channels with a diameter of greater than 12 nm and an average particle diameter of less than 30…
This work studied the interaction between carbide precipitation and impurity segregation under temper embrittlement (TE) conditions in a coarse-grained heat-affected zone (CGHAZ) in Q690 steel, a low-alloy high-strength structural steel used in the hydraulic support in the fully-mechanized mining face. From the perspe…
The interaction of iron-carbon melts with additions of alloying elements Cr, V, Ti, Mn, Ni, Cu, Mo, Al, and W during their dispersion by nitrogen is studied by thermodynamic simulation. It is shown that the nitrides of iron, chromium, titanium, aluminum, tungsten, vanadium, and molybdenum and Fe 3 C, Cr 3 C 2 , MoC 2…
Styrofoam (EPS) lightweight concrete, a new type of lightweight aggregate concrete, whose superior thermal performance and remarkable economic benefit earns more and more attention from the engineering. Adding nanoSiO2into it can improve the frost resistance of EPS lightweight concrete, so that it can improve the micr…
The topological constraints necessary to enhance hydrogel gelation efficiency are explored by C. Alemán, D. D. Díaz, and co-workers. On page 4893, the performance of hydrogels made from DABCO-containing ionene polymers is studied and compared based on the critical gelation concentration, gelation kinetics, thermal and…
As the needs of profiled rings continuously increase, studies about profiled ring rolling processes is becoming a hot problem. This paper established a FE model of hot ring rolling process of inner L-shaped ring based on ABAQUS/Explicit software. The reasonable value range of mandrel feed rate is determined at first.…
Energy savings in electrical appliances and electric vehicles can be realized by reducing the power consumption of motors operating for variable-speed drive. In order to reduce the energy consumption of such electrical devices, flux-weakening currents are used to reduce the voltage at high rotational speeds, which lea…
In this paper, the bamboo-poplar composite oriented strand board (OSB) with different hybrid ratios were aged under the standard of ASTM D1037 to evaluate its weathering performances. The thickness swelling (TS), water absorption, modulus of rapture in perpendicular direction (MOR⊥), modulus of elasticity in perpendic…
While searching for adequate sol-gel methodologies for successfully trapping in monomeric and stable form either porphyrins or phthalocyanines, inside translucent monolithic silica xerogels, it was discovered that the interactions of these trapped tetrapyrrole macrocycles with Si-OH surface groups inhibit or spoil the…
In the present work we investigate the influence of acceptor (K+, Cu+, Li+), donor (La3+, Bi3+, Eu3+, Nd3+, Y3+, Cr3+) and charge equivalent dopants (Sr2+, Co2+, Mn2+, Ta5+) on the dielectric and ferroelectric behavior of 0.92 Pb(Mg1/3Nb2/3)O3-0.08 PbTiO3(0.92PMN-0.08PT). As a criterion for the basic suitability for e…
Abstract Corrosion is commonly defined as the deterioration of a material or its properties because of a reaction with its environment. It is a natural process due to a high energy state induced in metals and alloys during refining, processing, and manufacturing. Modern methods for preventing and controlling corrosion…
В настоящее время все большую популярность приобретают полимерные композиционные материалы (ПКМ), получаемые методом пропитки расплавным связующим, вытесняя традиционные ПКМ, получаемые пропиткой растворными связующими. Это сделало возможным появление новых перспективных путей переработки ПКМ и позволило упростить и у…
In this work, the structural characterization of thin films using a conventional diffraction equipment, brand X'Pert PRO PANalytical X-rays is described. A brief review of the theoretical diffraction techniques and X-ray reflectivity is included. In the experimental part the conditions necessary for the assembly of th…
This paper presents the study of Microwave Incinerated Rice Husk Ash (MIRHA) Influence on Foamed Concrete (FC) Workability. The mix proportion of the MIRHA FC was designed using the Taguchi method with L 16 orthogonal array with five parameters, namely, MIRHA contents, water cementitious ratio (w/c), sand cement ratio…
The commercial lithium salt LiPF6 is extremely sensitive to moisture and easy to thermally decompose, which causes a catastrophe especially under high temperature conditions. The lithium borate salts with highly thermal stability and environmental benignancy have been developed and received extensive attention. Resear…
