A novel mesoporous composite water purification material was synthesized from natural zeolite to possess certain water purification properties as well as in proper particle size range for optimal fluid flow, particle retention and mass transfer in fixed bed applications. The meerschaum was used as the framework material in the experimental manufacturing procedure, polyethylene alcohol with carboxylic methylic cellulose was used as cohesive reagent, and H2O2 as bubble-forming agent. And the resulted granular product has good abrasion resistance ability with the measured impact breaking time reaching 12 hours. In addition, its decoloring rate is only 4. 4% lower and its CODcr removing is only 13. 2% lower than those of the original powder product, respectively. As a whole, the granulation potential and significantly expands the zeolite wastewater treatment application range with (only is not necessary) minor reduction of its treatment efficiency. © (2012) Trans Tech Publications, Switzerland.

In order to expand the development of health edible functions of Acanthopanax leaves, to meet people's demand for low care wine, Acanthopanax low alcohol wine was studied. Corn without Germ and Acanthopanax leaves are main materials, using double enzyme saccharification, low-temperature fermentation technology to produce low-alcohol wine. Saccharification process conditions was optimized by orthogonal experiment. The results showed that: Liquefaction time was 50 minutes, saccharification temperature was 55 □, glucoamylase dosage was 200U / g, pH5.0, saccharification time was 80 minutes, dosage of Acanthopanax leaves was 1.5 g / L. After Low-temperature fermentation, the alcohol concentration in an average was 4.5%. The appearance of wine was slightly yellow, clear and transparent. Because of a unique flavor and bitterness, no odor, and immune function, anti - fatigue, treatment of insomnia and so on, Acanthopanax low health wine has broad market and prospects. © 2011 IEEE.

Some living creatures have special structures on their body surfaces, such as smooth and elastic epidermis with subcutaneous tissue having non-smooth structures under certain conditions. The elastic epidermis coupled with non-smooth structures has a special function called bio-coupling functional surface. Imitating this functional surface and applying it in engineering has a potential to solve some engineering problems. Based on the simulation method of fluid-structure interaction (FSI), simulation calculation of the bionic functional surface coupled by the two factors, form and flexible materials was conduct using ADINA software. A viscous and weakly compressible transient flow was selected as a working medium, a discrete solver was selected in numerical calculation and the basic κ - ε model was chosen as a turbulence model. It is assumed that the coupling surface of the form/flexible materials results is large deformation and large strain. The boundary condition of fluid-structure interaction was set as the calculation surface. The simulation results showed that this coupling is a dynamic process, in which the two factors (form and flexible materials) are influenced by the flow field. As the pressure and velocity of the flow field increase, the coupling process changes from partial coupling to complete coupling, the pressure drag decreased due to the maximum effective stress of bionic coupling surface is very small and the smooth and flexible materials can redistribute pressure by absorbing and releasing energy, the pressure drag thus formed is decreased. Moreover, non-smooth structures (form factor) coupled with flexible materials reduced velocity of working face and minimise energy losses effectively, enabling the bionic coupling surface to reduce drag. © (2014) Trans Tech Publications, Switzerland.
