The microstructure and properties have been analyzed of cold rolled TRIP steel for C-Mn-Al bearing.Results show that the properties of the trial steel are almost as equal as that of the traditional TRIP steel,the TRIP effect can be produced under the appropriate production process.The retained austenite volume fractio…
Objective To investigate the lymphatic targeting of 5-fluorouracil(5-FU) carbon nanoparticles in rats. Methods 5-FU concentration in lymphoid tissue of rats was determined by reversed phase high performance liquid chromatography after intraperitoneal injection of 5-FU carbon nanoparticle and 5-FU ordinary form(20 mg/k…
Heterogeneous reduction mechanism of NO on the surface of nitrogen-containing char was investigated at molecular level using density functional theory.The char model,products,stable intermediates and transition states were optimized at B3LYP/6-31G(d)level.The whole potential energy surface was obtained by calculating…
The current investigation was carried out to find a method to remove dimethyl sulfide in the black liquor gasification gas for preparing the standard gas combusting in gas turbine.A simulating experiment to remove dimethyl sulfide was taken in the condition of hydrogen atmosphere,high temperature and with ZnO catalyst…
Ti powder,Al powder and carboxyl-contain-ing polymer were used as the starting materials to prepare a water-borne paint.Resultant water-borne paint was then prepared into Al-Ti composite anticorrosive coating on low carbon steel surface via a thermocuring route.The optimized condition for preparing the Al-Ti composite…
The aim of this paper is to describe the polarization properties and electric-optic properties of the twisted nematic liquid crystals.When the incident linear-polarized light has travelled through the liquid crystal without electric field,the rotation of the plane of polarization with π/2 is an over-simplified descrip…
In the paper,two typical Mg alloys(AZ31 and AZ91HP) were irradiated using high current pulsed electron beam(HCPEB) for the purpose of enhancing friction and wear property of Mg alloys.The microstructure of surface modified layer of two alloys was studied by scanning electron microscope(SEM) and X-ray diffractometer(XR…
A kind of wear-resisting cleading of high-chromium cast iron was produced and its heat treatment was carried out with quenching at(980±5) ℃ for 3 h and tempering at(220±5) ℃ for 3 h.The microstructure and the hardness of the wear-resisting cleading was observed and examined.The effects of heat treatment on microstruct…
The graphite-like materials were received by thermal chemical vapor deposition(CVD),The microstructure and surface morphology of the graphite-like materials were characterized by Field emission Scanning electron microscope(FESEM) and Raman.The measurement results revealed that graphite-like materials were consisted of…
Tetraphenylporphyrin(TPP),as a precursor,was synthesized from benzaldehyde and pyrrole by Adler condensation.2-Formyl-5,10,15,20-tetraphenyl-porphyrin(FTPP) was obtained by Vilsmeier reaction from TPP.A series of tetraphenylporphyrin derivatives were synthesized via Wittig reaction based on FTPP.Their structures were…
Edible gelatin films based on shark skins were successfully prepared.The effect of protein concentration,glycerol content and environmental humidity on the properties of edible gelatin films was investigated.As a result,white and transparent gelatin films could be produced using shark skins.With increasing protein con…
On the basis of Bardeen-Cooper-Schrieffer(BCS) theory and self-consistent calculation of the Bogoliubov-de-Gennes equations,this paper investigated proximity effect on a superconducting graphene with s-wave pairing and graphene junction structure.The dependence of the local density of states and pairing amplitude on t…
The influence of heat treatment on the microstructure and properties of die-cast aluminum alloy G01 containing trace La and Cr elements was studied in this paper.The mechanical performance and microstructure of heat-treated alloy were investigated by the tensile strength,hardness,impact toughness test and SEM observat…
The normal breakdown for the DANIELI high speed wire rod mill is analysed and the relevant solution and precaution are raised in this paper.
The blocked silicone-modified water-borne polyurethane is prepared with toluene diisocyanate(TDI),polypropylene glycol(N220 and N330),dimethylolpropionic acid(DMPA),hydroxyl-terminated silicone(KF-6001)and methyl ethyl ketoxime(MEKO).The chemical structures are characterized by Fourier transfer-infrared ray(FT-IR) ana…
