The characteristic microstructures around the crater in 2519A—T87 alloy impacted with projectile were investigated though optical microscopy(OM) and transmission electron microscopy(TEM).The deformation bands and adiabatic shear bands were found at the crater wall,and the micro-cracks have been germinated and develope…
The carbon content of Railway wagon ferritic stainless steel in CGHAZ is proportional to grain size and martensite.As carbon content increasing,the grain coarsening of CGHAZ is inhibited,thus,the impact toughness and fatigue strength are significantly improved.The existence of martensite in the impact toughness and fa…
Aim To fabricate carbon nanotube field effect transitor(CNT-FET) with CNTs oriented network as the conducting channel by simply technique.Methods CNTs were purified by oxidation and acid treatment,then CNTs oriented network was formed over source and drain using high-frequency alternating current(AC) electrophoresis.T…
Ester-based quaternary ammonium gemini surfactant is prepared with nylon acid,epichlorohydrin and N,N-dimethyl dodecylamine as raw materials.The effects of reaction time,temperature and the dosage of catalysts on the yield of product are studied,finally the optimum reaction conditions are obtained.The product structur…
New catalytic materials have become present research focuses,mainly including nanometer materials,inorganic organic composite materials,ionic liquids,metal nitrides and carbides,etc.To review the preparation,property and technology progress of these materials.
The core of innovation in denim is to give the denim new functions while improving its hygiene properties.The premise is to keep the unique jean style of traditional denim unchanged.A kind of new pearl fiber denim is introduced,which not only improves the hygiene properties of traditional denim,but also endows the den…
According to raw water quality of a pharmaceutical enterprise in Hebei province,a new low phosphonic water treatment agent HB-987 was developed with phosphonocarboxylic acid,phosphono polycarboxylic acid and polycarboxylate as main agents.The performance of corrosion and scale inhibition were investigated by limited c…
cellulose produced from cellulose-degrading anaerobic bacteria has unique advantages in application.This research is aimed at searching for the optimal carbon source and optimal nitrogen source for butyrivibrio fibrisolvens WH-Q,a cellulose-degrading anaerobic bacterial strain.singel factor experiments are made and th…
TiO2-MoO3 composite nanotube thin films were obtained by the thermal treatment of titanium dioxide nanotube thin films in the presence of MoO3.Titanium dioxide nanotubes(TiO2 NTs) thin films were prepared by the anodic oxidation of titanium foil.The resultant thin films were characterized by X-ray diffrac-tion(XRD),sc…
AZ31 magnesium alloy was easy to form strong fiber texture during conventional forward extrusion.In this study,a typical extrusion microstructure was characterized by EBSD technique.The result showed the texture of the extruded sample was not a uniform ring fiber texture with all the(0002) basal plane parallel to extr…
Chitosan is one product of deacetylated chitin.Chitosan can be used for improving animal immunity and acting like antibiotics in animal production as one of the green feed additives.This article reviewed the research advances in the nature,functional mechanism and the application of chitosan in animal production.
Pseudo-glow discharge was used to modify the surface of cotton fabric to improve the hydrophobicity by using hexafluoropropylene(C3F6) as the monomer and helium(He) as the carrier gas at atmospheric pressure.Effects of discharge time,power,concentration and other conditions on the water repellency of the treated fabri…
This experiment first applied sisal fibre to the asphalt concrete,and in the light of AC-13 goals proportion confirmed sisal fibre optimum content of 0.2%.Test results show that,join sisal fibre can markedly improve the high temperature stability of asphalt concrete,the low-temperature cracking-resistance,the properti…
Paraffin/γ-Al_2O_3 composites as phase change energy storage materials were prepared by absorbing paraffin in porous network ofγ-A1_2O_3.A series of characterization were conducted to analyse and test the performance of the composite materials,and differential scanning calorimeter(DSC) results showed that the PCM-3 co…
Liposomal targeting system makes antitumor drug combine with target tissue.Encapsulated into liposomal targeting system,antitumor drug could target and release into the target tissue with controlled character.Targeting system could enhance the effect of antitumor drug and prevent some side effects.This article reviews…
Modification of the mesoporous molecular sieve has been a hotspot of research in recent years.FSM-16 modified by iron was used to catalyze phenol with hydrogen peroxide to produce dihydroxybenzene.The Fe contents,amount of the catalyst,reaction time and reaction temperature that affect catalyst performance were in res…
The production technologies of bamboo/fine count polyester were studied based on their properties.The spinning and weaving processes of newly - developed fabric and its design application were introduced.The cohesive force of the two fibers is large,with tight yarn,high yarn strength,less hairiness,smooth appearance,a…
The effects of reactive dyes printing between modified guar gum and sodium alginates were compared on the cotton fabrics including a variety of their properties tested.Experiments indicate that modified guar gum has high rate of paste,the PVI value of modified guar gum is lower than sodium alginates's,cotton fabrics u…
The β-cyclodextrin-co-succinic anhydride magnetic polymer microspheres were prepared by inverse emulsion polymerization with magnetic Fe3O4 nano-particles modified with oleic acid at low-temperature and washed with distilled water as the core,β-Cyclodextrin(β-CD) and succinic anhydride(SA) as raw material.Then structu…
The Ce(0.8)Nd(0.2)O(1.9) (NDC) (<50 mg.kg(-1) Sift) and 500 mg.kg(-1) Sift of Ce(0.8)Nd(0.2)O(1.9) (NDCSi) with and without 1mol% MoO(3) systems were prepared by the so-gel method. The characterizations of samples were investigated by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and A…
