The highly ordered mesoporous MCM-41 was synthesized and modified with various content of aluminum (0-15%) using an incipient wetness impregnation technique. The prepared Al modified MCM-41 materials were characterized by XRD, and explored as adsorbents for arsenic(V) removal. Al loading and calcination temperature played significant roles in the absorbents structures and adsorption capacities. The maximal arsenic(V) adsorption capacity of 16.3 mgAs/gAl was obtained when Al loading of 10 wt% and calcination temperature of 400 °C were used.

This research presented the kinetic performance of arsenic absorption by mesostructure SBA-15 functionalized with Al2O3. The SBA-15 was previously synthesised and subsequently functionalized via impregnation of alumina oxides. The absorption of arsenic(V) was studied as a function of absorbent dosage and contact time. The experimental data were fitted to kinetic pseudo-first order, pseudo-second order and the intra-particle diffusion model. The pseudo-second order model presented the best correlation with the experimental data. Both surface absorption and intra-particle diffusion were acting during arsenic uptake, except for absorbent dosage of 0.1g, which was mainly controlled by the intra-particle diffusion.

Rehabilitation technical aids have an important role in the functional rehabilitation of children with cerebral palsy. But now the rehabilitation technical aids for cerebral palsy is lack of pertinence and evaluation. The testing equipment of rehabilitation technical aids for cerebral palsy child can detect the pressure distribution between cerebral palsy patients and rehabilitation props in real time, and provide quantitative basis for clinical effect evaluation and auxiliary tool’s adjustment. This paper design a pressure monitoring system with 16 sensor points for Cerebral Palsy Children, and the monitoring system is mainly composed of three parts: a strain gauge array unit, signal conditioning and acquisition unit, data display and analysis. The research on pressure monitoring system based on the strain chip, is critical to study force between rehabilitation technical aids and cerebral palsy children. In this paper , the works on the detailed description of each unit system, and reasonable verification of the experimental design provide solid foundation for the future studies.

Nickel-plated steel sheet with high ductility and wonderful corrosion resistance, it has been widely used in industry. Stamp forming is a high-volume fabrication method for producing desired components. To determine the optimum values of the process parameters, it is essential to find their influence on the deformation behaviors of the steel and nickel. In this paper, finite element method (FEM) simulation was carried out to analyze some factors such as stress distribution, strain distribution, and fillet radius.

Ultra-precision mould is widely used as the most important material in hot forming manufacture industry in recent years. Hot forming process has been employed as a promising technique to manufacture small size components in mass production. In this paper, an effective method of improving the heating or the cooling effectiveness is to increase the area exposed to the cold or hot nitrogen by means of adding slots. In the same condition, four models with different slots were built. Based on the theoretical analysis of glass heating and cooling property in the forming process, finite element simulation was carried out. The results showed that the model with slots may decrease the heating and cooling time

Sheet forming is a high-volume fabrication method for producing lightweight materials components. An important goal in manufacturing research is to determine the optimum method for producing products with less cost. In this paper, combined with the orthogonal test method and finite element method (FEM) simulation, the analysis was carried out to analyze the key process factors such as stamping force, fillet radius, and friction coefficient. Using orthogonal test method can reduce the testing time, learn how the molding parameters influence the total equivalent plastic strain, acquire the best match forming parameters, and give guidance for the better condition

The cooling and heating resources contained in urban sewage have significant influence on the “energy conservation and emission reduction”. From the point of extensive utilization, the paper put forward the concept of sewage thermal-energy utilization plan, and discussed the types, goals, principles, content and steps of the plan. Selecting principles and flow-volume calculation method of flow nodes were also illustrated. The study results provide reference for industrialization of urban sewage thermal-energy resources application in construction.

Sewage discharged form urban dwelling community is warm in winter and cool in summer, which is a sustainable resource and has not utilized fully. Sewage-source heat pump (SSHP) system has advantage of energy efficient, economic, environment friendly and broad foreground, which has significance for the development of building energy efficiency (BEE). The past research of SSHP usually set the heat source and heat sink in sewage farm or main-pipe of urban sewage system, and few take the cesspool of dwelling community as heat source and heat sink directly. The author wanted to develop SSHP system by using sewage on the spot of cesspool in urban dwelling community. He chose a representative urban dwelling community from Chongqing and has tested the temperature and flow volume of sewage for more than one year. Based on testing data, the paper developed SSHP applying schemes for air-conditioning, heating and hot-water supplying, which can be handy-applied in the urban dwelling community. The research of this paper aims to broaden the use of SSHP and promote the development of BEE technology.
