Langmuir-Blodgett assembly of ultra-large graphene oxide films for transparent electrodes

Monolayer ultra-large graphene oxide （UL-GO） sheets with diameter up to about 100 μm were synthesized based on a chemical method. Transparent conductive films were produced using the UL-GO sheets that were deposited layer-by-layer on a substrate by the Langmuir-Blodgett （L-B） assembly technique. The films produced from UL-GO sheets with a close-packed flat structure exhibit exceptionally high electrical conductivity and transparency after thermal reduction. A remarkable sheet resistance of 605 -/sq at 86% transparency is obtained, which outperforms the graphene films grown on a Ni substrate by chemical vapor deposition. The technique used to produce transparent conductive films is facile, inexpensive and tunable for mass production.

Safety assessment of platform loadout procedures based on unascertained measures

Safety assessment of offshore platforms is an urgent task. Such assessments are now focusing on the structure, maintenance, and retirement of a platform. Some methods employed have many shortcomings. For example, they cannot make the reliability adequately explicable. Therefore, a mathematical tool, the unascertained measure, was introduced. First, the basic knowledge of the unascertained sets was introduced briefly. Second, the unascertained measure was defined and credible identification was set up. The method has been introduced into the fields for safety assessment of a jacket loadout procedure. Engineering practices showed that it can complete the safety assessment systematically and scientifically without any assumption. The work should have significance in theory and practice for offshore engineering.

Unraveling the Pattern Weaving Technology in Ming Dynasty

The Ming dynasty （1368 - 1644） inherited the lens-standing culture in China, of course including the textile technology. Besides a large amount of sinsle color damask silk, many pattern woven silk including dragon robes, patterned costumes and luxurious silk textiles are found in complicated and colorful pattern woven brocade called zhuang hua. It was prevailed in Ming dynasty when compared with the frequency of the name chuang hua recorded in related historical documents. These pattern silk and brcrade were produced by the advanced pattern weavin8 technology, which was well developed in Ming dynasty. From historical documents of＂Tian gong kai wu＂, Exploitation of the works of nature, there is the detailed description of the draw loom （hua Io ji） which can weave normal patterned textiles. It also indicated that to produce dragon robes needed much more high technique, similar to the hua Io ）i but more complicated and difficult. A big draw loom is found to weave Nanjing Yen brocade today inherits the technolosy to weave zhuang hua brocade. After sorting the historical documents, it is found that some records are coincident with the existed materials, both the silk textiles and weaving technology. With these evidences research and exploration, this dissertatien tries to unravel the pattern weaving technolosy in the Ming dynasty.

Evaluation of Selected Quality Degradation Indices for Palestinian Extra Virgin Olive Oil Bottled in Different Packaging Materials upon Storage under Different Lighting Conditions

The effect of packaging materials and lighting conditions on quality of extra virgin olive oil （EVOO） was investigated during six months. The results highlighted an influence of light and type of packaging material on EVOO-quality with storage time. At shelf, all packages maintained EVOO at the end of storage in terms of acidity, peroxide value, K232, while K270 exceeded limit of EVOO in glass and PET-stored oil. Loss of phenols was the highest in glass-stored oil and the lowest in high-density polyethylene （HDPE）-stored oil. In terms of sensory evaluation, glass-stored oil lost EVOO grade after three months and its edible compliance after six months, while HDPE-stored oil maintained EVOO grade 90 days and was virgin after six months. In extended lighting, acidity, peroxide value and K232 did not exceed EVOO grade, while K270 exceeded EVOO grade after 30 days in glass and polyethylene terephthalate （PET）-stored oil and after 90 days in HDPE. The loss of phenols was the largest in glass and smallest in HDPE-stored oil. Glass stored-oil lost organoleptic edible compliance before 90 days, while that in PET was virgin at 90 days and that in HDPE maintained EVOO quality 90 days. At the end of experiment, oils in all packages were not edible. In dark, all packages maintained oil in EVOO quality in terms of all indices. The loss of phenols was marginal but was the least in glass and the highest in HDPE. It was concluded that HDPE bottles conserve stored olive oil at shelf or illumination better than PET or glass, while in dark, glass was superior over plastic.

Shear localization behavior in hat-shaped specimen of near-αTi−6Al−2Zr−1Mo−1V titanium alloy loaded at high strain rate

The microstructure characteristics in early stage shear localization of near-αTi−6Al−2Zr−1Mo−1V titanium alloy were investigated by split Hopkinson pressure bar(SHPB)tests using hat-shaped specimens.The microstructural evolution and deformation mechanisms of hat-shaped specimens were revealed by electron backscattered diffraction(EBSD)method.It is found that the nucleation and expansion of adiabatic shear band(ASB)are affected by both geometric and structural factors.The increase of dislocation density,structure fragment and temperature rise in the deformation-affected regions provide basic microstructural conditions.In addition to the dislocation slips,the extension twins detected in shear region also play a critical role in microstructural fragmentation due to twin-boundaries effect.Interestingly,the sandwich structure imposes a crucial influence on ASB,which finally becomes a mature wide ASB in the dynamic deformation.However,due to much larger width,the sandwich structure in the middle of shear region is also possible to serve as favorable nucleation sites for crack initiation.

The influence of the designing styles of the furniture in the Ming Dynasty on the modern furniture

As the development of the current building activities continues to become mature, now the requirements on the indoor design activities will also be promoted. Compared with the interior design activities, the furniture is one of the important factors in the process of the interior decoration. The choice of the appropriate furniture not only can effectively improve the quality of the interior design activities, but also can fully meet the specific application needs of the people. This paper starts from the analysis of the specific requirements on the design and production of the modern furniture. And combined with the analysis of the specific characteristics and the connotation of the design styles of the furniture in the Ming Dynasty, the author further explores the specific influence of the design styles of the Ming Dynasty furniture on the modern furniture.
