A series of multiplex ceramic photo-catalysts of nanometer titanium dioxide(Al2O3-SiO2-ZrO2-TiO2) was prepared by Sol-Gel. The ratio of Al∶Zr∶Si∶Ti is 4∶1∶1∶1(molar ratio) . Then the composite catalyst Of Al2O3-SiO2-ZrO2-TiO2 was modified by doping rare-earth element,Tb in accordance with the amount of Ti. The composi…
The Mo-Ti-Zr alloy bars were prepared by cold isostatic pressing, high temperature sintering and direct rotary forging. The effects of the annealing temperature on the mechanical properties and microstructure of the alloy and the annealing behavior of this rotary forging Mo-Ti-Zr alloy bars deformed by 30% were invest…
By means of microscopic analysis,X-ray diffraction,electron probe microanalysis,thermal analysis and physical property analysis,the optical features,chemical component and occurrence of the Pb-bearing arsenate mineral in a limonite ore of Fujian were investigated thoroughly,and ultimately,it was found out that this mi…
Based on 4,4′-dicyclohexyl methane diisocyanate(H12 MDI)/1,4-butane diol(BDO)as hard segment,polytetramethylene oxide glycol(PTMEG)and poly butylene adipate(PBA)as soft segments,a few series of polyurethanes elastomer with different hard segment contents between 23 wt%-50 wt% was prepared.With IR and DSC used to inves…
Polyester pongee fabric was modified by atmospheric pressure dielectric barrier discharge technology,and the influence of dischage power and discharge duration on the wettability of the fabric was discussed.Attenuated total reflection infrared spectroscopy and X-ray photoelectron spectroscopy were used to study the su…
In order to improve the tribological property of AISI 52100 steel,FeS powders were used as an additive in lithium grease,and an iron sulfide layer on top of 52100 steel was prepared by using a low temperature ion sulfuration technology.The tribological properties of sulfide layer and FeS powders were investigated on a…
Layered double hydrotalcites(LDHs) are important inorganic materials with layered structure and anion exchangeable capacity.These Mg~(2+)/Al~(3+)(OH)_6 octahedra form two dimensional sheets via edge sharing and stacked together by hydrogen bonding between the hydroxyl groups of adjacent sheets.In LDHs,isomorphous repl…
The synergistic flame retardant effect of carbon black/magnesium hydroxide,red phosphorus/magnesium hydroxide and zinc borate/magnesium hydroxide in silicone rubber was investigated.The results showed that,compared to magnesium hydroxide alone,carbon black/magnesium hydroxide had significant synergistic flame retardan…
Corrosion behavior of carbon steel in urban sewage was studied by weight-loss and electrochemistry methods,then corrosion product was examined with SEM and EDX.The results showed that during long time immersion in urban sewage,the corrosion rate of carbon steel was stable by ca.0.8 mm/a and the flow of water increased…
OBJECTIVE: To observe the protective effect of reduced glutathione(GSH) against cisplatin-induced nephrotoxicity.METHODS: 100 cancer patients were randomly divided into two groups,with the nephrotoxicity evaluated comparatively.RESULTS: The response rate of combination chemotherapy chiefly cisplation was above 53%, an…
Bisphenol-A bis(diphenyl phosphate) was synthesized by phosphorus oxychloride bisphenol-A and phenol.The effect factors of process were studied respectively, including molar ratio and reaction temperature.The suitable synthesis conditions were studied.As follows: in the first step,the molar ratio of phosphorus oxychlo…
The Zn1-xMgxO(x=0.1,0.2,0.3,0.4,0.5,0.6(mol))thin films were prepared on glass substrate by the Sol-Gel method.The X-ray diffraction results showed that when the value of x was between 0.1 and 0.3,the thin film had the structure of hexagonal wurtzite while the angel of the diffraction peak became bigger with x,and the…
The research progress of degradable plastics is reviewed with focuses on the development in biodegradable polymers,and some new synthesis and modification methods are summarized.The specifications of national standards for properties testing of degradable plastics are listed in detail,including evaluation of mechanica…
In the paper,Na-montmorillonite modified by acrylamide was carbonized for 4 h at 200 ℃,400 ℃ and 600 ℃ and got pillared montmorillonite.Surface shape analysis of samples with Scanning Electron Microscope,testing specific area,pore volume and distribution of pore size with specific surface area and pore size analyzer o…
Introducing a kind of super-speed even needle vestige prepares the system of the pinprick machine constitutes and its design important point.
A Searle type rheometer was used to investigate the steady state rheological behavior of semisolid SCN-5at.%Wat. transparent alloy. The steady state apparent viscosity of semisolid SCN-5at.%Wat. alloy exhibits a shear thinning phenomenon,which is similar to that for semisolid metallic alloy slurry. The steady state ap…
Making use of the characteristic of temperature change with the position in plasma nitriding furnace and the influence role of heating speed on ununiformity of furnace temperature,the distortion problem of large-sized slide plate after plasma nitriding was solved;and the machining distortion was also compensated.The e…
