Activated carbon (AC) injection has been regarded as one of the most effective control technologies for Hg0 removal in flue gas. It is worthwhile to explore new and simple preparation methods for AC with low cost and high Hg removal capacity. In this study, a biomass based AC was successfully prepared from levant cotton exocarp using ZnCl2 activation. The mercury adsorption efficiency and mechanism were studied via the fixed bed experiments. Activator, reaction temperature and components of simulated coal-fired flue gas were investigated. Brunauer–Emmett–Teller (BET), scanning electron microscopy with energy-dispersive X-ray spectrometry (SEM–EDX) and X-ray photoelectron spectroscopy (XPS) were applied for morphology characterization of the prepared AC and discussion of the possible adsorption mechanism. The adsorbed mercury species and the physiochemical properties of prepared AC were discussed. The results showed that (1) Hg0 removal efficiency could reach up to 90% at 150 ℃ under simulated flue gas (SFG); (2) Hg0 adsorption was controlled by the combination of physical and chemical mechanisms.

In the present work, a comparative study of the mechanical behavior of two series of elastomeric composites, based on carboxylated styrene butadiene rubber (X-SBR) and reinforced with rice bran carbon (RBC) and graphite, is reported. Hybrid composites of X-SBR filled with RBC-graphite were also investigated in terms of the cure characteristics, hardness, tensile properties, abrasion resistance, and swelling. It was observed that the cure times decreased with the incorporation of a carbon filler whereas the torque difference, tensile strength, tensile modulus, hardness, and swelling resistance increased compared to the neat X-SBR revealing a favorable characteristic of crosslinking. Dynamic rheological analysis showed that the G' values of the composites, upon the addition of RBC-graphite, were changed to some extent. This demonstrates that the presence of a strongly developed network of fillers will ensure a reinforcing characteristic in a polymer matrix.

Many advanced ground-based solar telescopes improve the spatial resolution of observation images using an adaptive optics (AO) system. As any AO correction remains only partial, it is necessary to use post-processing image reconstruction techniques such as speckle masking or shift-and-add (SAA) to reconstruct a high-spatial-resolution image from atmospherically degraded solar images. In the New Vacuum Solar Telescope (NVST), the spatial resolution in solar images is improved by frame selection and SAA. In order to overcome the burden of massive speckle data processing, we investigate the possibility of using the speckle reconstruction program in a real-time application at the telescope site. The code has been written in the C programming language and optimized for parallel processing in a multi-processor environment. We analyze the scalability of the code to identify possible bottlenecks, and we conclude that the presented code is capable of being run in real-time reconstruction applications at NVST and future large aperture solar telescopes if care is taken that the multi-processor environment has low latencies between the computation nodes.

The mind-body problem is one of the basic problem of Chinese traditional philosophy , which is dated back to Qing dynasty . Mind is subject , and body is object , how its relationship does work confused the ancient Chinese philosopher for thousands years , it also influences the way the Chinese people see the nature , the society , and themselves . The main trend of the thoughts considered the mind and the body should be in a harmony , and the mind is the commander . The principle grows in nature , and the essence always in mind . The golden mean of the Confucian school tells the inside and outside of the Dao is always together . This article will analyse the logic of the chinese traditional mind , and use the Chinese tradtioanl arts as the examples , especially the Chinese traditional opera and the traditional painting . We know the arts is directly related to the artists' mind , and the way they see the world . A conclusion will be get : the logic of Chinese traditional mind is a dialectical truth . Compare with the western ancient artists who is loyal to their eyes , the Chinese traditional artists pay more attention to their mind . The truth of former's work is based on the original look of the world , but the truth of the Chinese arts is a subject world which reflected the outside , namely the harmony of the inside and outside
