The most expensive and principal step in the process of converting cellulosic biomass into biorenewables and biofuel is the pretreatment during which lignin and cellulose crystalline structure is broken down. In this study, TiO2 nanoparticles were utilized as photocatalyst in addition to alkaline (ammonia and sodium hydrate) treatment of corn stover biomass to improve delignification ability and reduce the energy and chemical loadings to make the process more environmentally friendly. Raman Spectroscopic imaging, as an accurate and rapid chemical characterization method, was utilized to investigate the molecular compositional and structural changes occurring during the pretreatment process in the corn stover biomass qualitatively. Lignin characteristic peaks at 1,600, 1,620 and 1,690 cm-1 as well as cellulose characteristic peaks at 1,059 and 2,888 cm-1 were identified through Raman Spectroscopic measurement as indicators of the effects of the pretreatment. Real-time quantitative analysis of these functional peaks revealed the molecular structural changes during delignification, potentially may lead to optimization of the processing parameters to reduce the processing cost in the future.

Cu-15Ni-10Mn alloy as-cast, which smelted at atmosphere, has a typical dendrite structure in Ni segregation characteristics. The content of Ni is higher on dendrite arms spacing than on the dendrite arms, but the content of Mn is less than on the trunk. Due to the Mn oxides easily, the processing performance of alloy as-cast cant meet the requirement of metalworking. The gas content of ingots can be reduced by adding a small amount of zinc during smelting, and the metalworking features can be improved by adding trace Ti that will refine the arms of alloy. The research results show that the grains of Cu-15Ni-10Mn alloy as-cast can be refined by tiny amount of Ti. The grain size decreases with the increase of the content of Ti, the branches size of alloy adding 0.2% Ti is about 30μm that is only 49.4% the size of the alloy without Ti. Titanium, copper and Nickel can form compounds of CuNi2Ti. The hardness peak of alloy with 0.2%Co is 114Hv that is 8% higher than the alloy without Ti. The electrical conductivity of Cu-15Ni-10Mn alloy as-cast waves not clearly.

The effect of polyethyleneimine (PEI) in precursor solution on the morphology and superconducting properties of YBa2Cu3O7-x (YBCO) films grown on LaAlO3 (LAO) substrates by metal-organic deposition (MOD) method was investigated. The morphologies of the YBCO films were different based on the different amount of PEI addition from 0.25 g to 0.9 g in 10 mL precursor solution. Furthermore, research results indicate that the PEI helps to improve the critical current density (Jc), the uniformity of surface morphology and c-axis orientation of thin film. The highest critical current density (Jc) of 2.17 MA/cm2 at 77 K is obtained in YBCO films fabricated on LAO substrates when the amount of PEI is 0.5 g in 10 mL precursor solution. YBCO layers with about 400 nm in thickness can be processed without cracks and holes during the whole heat treatment, which takes only 7.5 h.

Calcium sulfate/hydroxyapatie (CaSO4/HA) composite bone fillers were fabricated through molding method. Their structure and properties were characterized by infrared spectroscope, scanning electronic spectroscope, x-ray diffraction and degradation test. The results show that HA crystals were attached to the CaSO4 crystals and prevented the growing of sulfate crystals. So their size is shorter than that of CaSO4 crystals prepared from pure CaSO4 semihydrate, and some even had defect. The resorption rate of CaSO4 bone fillers was decreased when HA was incorporated.

One of the main hurdles for the wide use of current Ag-filled conductive composites is the high cost of Ag fillers, while the challenge for low cost copper-filled composites is their poor reliability. In this study, the Ag-coated Cu flakes was chosen as conductive fillers and a surface modification with coupling agent, to achieve good bonding between the flakes and the Polydimethylsiloxane (PDMS) matrix, was applied to improve the mechanical and conductive properties of the PDMS based composites. The resulting composites obtained through modification showed an increase in hardness by 13.1% and tensile strength by 28.4% relative to the composites without coupling agent. In addition, the reliability of conducting composites was discussed and the results showed that the coupling agent played a great role in preventing the corrosion of the exposed Cu during aging. The volume resistivity of the composites, filled with untreated Ag-coated Cu flakes, increased from 0.0039Ω·cm to 0.0059Ω·cm under aging at 85°C and 85% room humidity (RH) in a temperature/humidity chamber for 48 h, in contrary, the volume resistivity shift of the composites with treated flakes was almost negligible, just changed from 0.0043Ω·cm to 0.0045Ω·cm. More importantly, the prepared conductive silicone rubber filled with Ag-coated Cu flakes with the resistivity (0.004Ω·cm) comparable to the relative commercial products can be used for electro-magnetic interference (EMI).

The construction of the cities in China is under rapid development. Large-scale construction and renewal cut off the trace of city history - our cities are losing memories, whereas the city renewal of Bunkyo Ward in Tokyo post-War is in “transition in harmony with natural and historic surroundings", which can bring happy memories to people everywhere. This paper collected historic photos of the main streets, views and spots in Bunkyo Ward in the last 50 years, and take many new photos at the same place. In comparison with old views, we can still see some sparse and existent vestiges, misty archaic rhyme through the new building and the view. Which in contrast, in the Central 817 Road in Fuzhou. From the comparison between present and past since the 1980s, we can figure out: the urbanization in modification process treated the old city in another attitude which leads to another results: Changed Scenes with No Memories.

In this study, a thixotropic agent was applied to improve the aspect ratio of the silicone rubber gasket and the resulting obtained through modification showed an increase in aspect ratio from 0.26 to 0.91 with the relative to the gasket without thixotropic agent. Compared with the silicone rubber without thixotropic agent, the mechanical properties of the silicone rubber with thixotropic agent were discussed and the results revealed that the shift was very small. In addition, using Ag-coated Cu dendritic powder as conductive fillers, conductive silicone rubber with the resistivity (0.004Ω·cm) was prepared comparable to the relative commercial products can be used for electro-magnetic interference (EMI). The reliability of the conductive composites under aging at 85°C and 85% room humidity (RH) in a temperature/humidity chamber for 48 h was also discussed and the results showed that the shift of the volume resistivity was almost negligible which can meet the actual needs completely.

A certain project of tri-tower suspension bridge of which the main span was 1080m was taken as a case study of the mid tower stability. A 3D beam FEM model has been carried out to investigate the global mechanical behavior of the bridge in which the internal force response to several different typical load cases were specifically concerned. Moreover, the cable spring stiffness to the mid tower was defined as the ratio of the initial horizontal forces acting on the top end of mid tower to the corresponding horizontal displacement. And the effect of this equivalent spring stiffness on the stability performance of the mid tower was compared to other tow constraint conditions to the tower including free constraint and pin constraint. The comparison showed that the cable equivalent stiffness was 4342kN/m when living load was acting along the whole main girder of the bridge while this value varied with different load cases. The difference between the effect caused by the cable spring stiffness and the free constraint was small indicating that the stability of the mid tower was not sensitive to the cable constraint. In addition, with the increase of the equivalent spring stiffness, the longitudinal buckling eigenvalue also became larger and gradually approached the condition of pin constraint.
