This project combined with today's Fabric trends and used a sense of cool colors such as green and blue, has designed cool multifunctional composite high-end fabrics and showed the appearance of cool fabrics more comprehensively in the form of clothing simulation results.

Abstract: The surface modification process for cotton fabric which was oxidized first, and then crosslinked with collagen was studied. The optimum oxidation process was as follows: concentration of sodium periodate 0.6g/L, time 2.5h, temperature 40°C, ratio of water and cotton fabric was 100:1. The method for surface modification of cotton fabric was determined from comparative analysis, and the optimum process: collagen solution concentration 6%, glutaraldehyde concentration 5%, reaction 40min at 30°C, ratio of water and cotton fabric was 100:1. Compared with original cotton fabric,the breaking strength and elongation of collagen modified cotton fabric decreased, while the dyeing percentage with acid dyes was increased and this means the surface of modified cotton fabric was covered with a large component of collagen.

Abstract: Nickel-based catalysts were prepared by impregnating at different calcination temperatures to solve the problems of short lifetime, coking and hard to regenerate of HZSM-5 catalyst which was widely used as bio-oil upgrading catalyst. The NiO loading was 8wt. %, and the calcination temperature was 350~650°C. The surface characteristics, catalytic and regenerative properties of the catalysts were also analyzed and compared. When the calcination temperature is 550 °C, the catalyst shows good properties and the conversion of toluene and guaiacol is 83% and 80% respectively. The results of life-tests show that the adding of active material can help extend the life and improve the anti-coking ability of the catalyst. The conversion of toluene and guaiacol keeps at 40% and 50% respectively after 6h continuously catalytic reaction. The macromolecule aromatics in the catalyst channel can be converted into micromolecule aromatics by the adding of NiO.

Abstract: Spinel Li_4-xK_xTi₅O₁₂ (x=0, 0.03) were successfully synthesized by a traditional solid-state method and systematically investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and the charge-discharge test, respectively. The results demonstrated that Li_3.97K_0.03Ti₅O₁₂ exhibited much better rate performance in comparsion with Li₄Ti₅O₁₂. At 0.2 C and 10 C, it delivered a discharge capacity of 173 mAh g^-1 and 124 mAh g^-1 respectively, and after 100 cycles at 10 C, 96.1% of its initial capacity was retained.

Abstract: Nowadays, people should pay more attention on the environment problems that had advent along with the development of rare earth metallurgy industry. A large number of water pollutant, air pollutant and solid pollutant were discharged in the process of synthesis of rare earth compound by precipitation and roasting process. In order to solve the industry pollution problems, a new technology route was developed for the preparation of lanthanum oxide using lanthanum chloride as raw material by oxy-hydrogen flame route. The experiment results showed that lanthanum chloride could directly convert to lanthanum oxide under high temperature by the combustion of mixture gas of hydrogen-oxygen that provided by oxy-hydrogen generator continuously. The phase composition of obtained product was characterized by XRD and the conversion rate of lanthanum chloride and the reaction mechanism were discussed.

Abstract: According to the preparation method of coal-water slurry, the paper tries to use the cattle dung and livestock wastewater as biomass and coal to prepare a new composite CWS. This new CWS utilizes biomass waste instead of some content coal and fresh water, and it shows similar property with CWS by pure coal. The co-slurrying properties and the influences of different types of coal of cattle dung and coal were studied. Experiments show that: the adding cattle dung and livestock wastewater could prepare slurry fuel better than not, the dry biomass dosage can reach 7%. Through the experiment detection biomass-CWS properties (such as heat, concentration, viscosity, granularity, sulfur and ash, stability, volatile, ash melting point, etc), we found the best ratio of cattle dung, coal, water and additives for co-slurrying, the best preparation conditions and the best kind of coal. As the result shown, the biomass-CWS is prepared by anthracite, cattle dung (dry) and additives, this respective content are 53%, 7% and 0.6%. Consider fresh cattle dung having 70% water, this CWS should be prepared by wet pulping and ball milling 15mins. Because of adding biomass and waste water, 7% soluble sylvite has been detected in the coal ash.

Abstract: Silicon film as a surface passivation layer is reported to reduce surface recombination on silicon nanowires (SiNWs) and thus enable to improve SiNW solar cell (SC) performance. A question yet to be answered regards the link between the silicon film assets and the solar cell performances. We investigated the effect of the properties of silicon films on the SiNWs SC performances by adjusting hydrogen dilution. Our results showed that the open-circuit voltage (Voc) and short-circuit current density (Jsc) of SiNWs SC increase until hydrogen dilution 10 and then decrease. An open-circuit voltage of 0.397 V and short-circuit current density of 18.42 mA/cm2 are achieved at optimized hydrogen dilution. Based on the analysis of silicon film properties we proposed that the increase of defect density with hydrogen dilution was the main cause for the deterioration of SiNWs SC performance.

Abstract: The Schiff base 4-methoxysalicylaldehyde thiosemicarbazone (MST) was synthesized and its corrosion inhibition effect on carbon steel in 0.5 M H₂SO₄ solution was tested via weight loss and electrochemical impedance spectroscopy (EIS) measurements. The results show that MST serves as an effective corrosion inhibitor for carbon steel. The corrosion rate of carbon steel decreases with the increase in concentration of MST. The adsorption of MST on the carbon steel surface conforms to the Langmuir adsorption isotherm.

Abstract: Much attention has been paid to membrane-type lithium adsorbents to overcome the shortages of the leakage of powder, poor permeability and difficult recycle for powder lithium adsorbents. In this work, a series of membrane-type adsorbents of spinel-type manganese oxides were converted from lithium manganese oxide precursor membranes by acid treatment. Precursor membranes were prepared by solvent exchange method using polyvinylidene fluoride (PVDF) and Polyether sulphone (PES) respectively as binders, powder LiMn₂O₄ as the precursor and N,N-dimethyl acetamide (DMAc) as the solvent. The preparation conditions were investigated by changing the binder and the concentration of powder LiMn₂O_4. The surfaces and morphology of membrane-type adsorbents were observated by scanning electron microscope. The comparation of the capacities of lithium desorption from precursor and adsorption for membrane-type adsorbents based on different binders shows that PVDF is more suitable to be the binder than PES with liquid film thickness of 0.25mm, and the proper concentration of PVDF and powered LiMn₂O₄ are respectively 12% and 60%.
