Transformation of Fibrous Membranes from Opaque to Transparent Under Mechanical Pressing Article
Chao Wang, Jing Zhao, Liu Liu, Peng Zhang, Xianfeng Wang, Jianyong Yu, Bin Ding

There is a great demand for transparent films, membranes, or substrates in the fields of intelligent wearables, electronic skins, air filtration, and tissue engineering. Traditional materials such as glass and plastics cannot satisfy these requirements because of the lack of interconnected pores, undesirable porosity, and flexibility. Electrospun fibrous membranes offset these shortcomings because they contain small pores and have high porosity as well as outstanding flexibility. Thus, the development of transparent electrospun fibrous membranes is of great value. This work reports a simple and effective way to develop flexible and porous transparent fibrous membranes (TFMs) directly from electrospun fibrous membranes via mechanical pressing, without employing any other additives. In addition, the relationship between the transparency performance and the molecular structure of the polymers after pressing was summarized for the first time. After mechanical pressing, the membranes maintained fibrous morphology, micron-sized pores, and desired porosity. Polystyrene fibrous membranes, which exhibited excellent optical and mechanical properties, were used as a reference. The TFMs possessed high transparency (∼89% visible light transmittance at 550 nm), high porosity (10%–30%), and strong mechanical tensile strength (∼148 MPa), nearly 78 times that of the pristine electrospun fibrous membranes. Moreover, this study demonstrated that transparent and conductive membranes can be fabricated based on TFMs using vacuum-assisted filtration of silver nanowires followed by mechanical pressing. Compared with indium tin oxide films, conductive TFMs exhibited good electrical conductivities (9 Ω per square (Ω·sq−1), 78% transmittance at 550 nm) and notable mechanical performance (to bear abundant bending stresses).

The multi-variable assessment method is a current trend for studying the health of river ecosystems. A system of candidate indices, including physica-l chemical parameters and nutrition parameters, algae index, macroinvertebrates index and fish index were set based on monitoringdata collected from the Taizi River basin in May 2009. Spearman's Rank correlations and Regression modelling were used to select compatible indices to build the metric-comprehensive assessment index which was applied to evaluate the Liaohe River healthy. The results indicated that the hole basin of Liaohe River was in poor healthy situation, the poor health sites was 146, account 83 % of total sites, were distributed in the Hunhe River, East Liao river and West Liao River basin where discharge of urban and industrial pollution was the primary factor impacting the river health. The other 17 % of all sites were designated as good healthy, mainly located at Taizi River basin, and the best sites was located at the headstream of Taizi River basin where little disturbanceby human activities occurred. About the biotic indicators assessment, fish community healthy level was the worst, the best one was algae.

Maximum entropy principle is imported into the basic complex method in order to improve the ratio of successful run. A new search idea is presented as follows: firstly the search optimum design point is defined as the design point whose entropy is the biggest among all the design points of the complex and a new better design point is found on the line through the search optimum design point and the integrated centroid of the remaining design points. A new complex is generated after the search optimum design point is replaced with the new better design point. The method iterates until the information of the complex is utilized thoroughly thereby proposing a new complex method. The basic complex method and the complex method based on maximum entropy principle are used to locate the critical failure surface with the minimum factor of safety of two non-homogeneous soil slopes and the comparisons of the results suggest that the ability of the complex method based on maximum entropy principle to find global optimum is stronger than that of the basic complex method.

Through investigation and onitoring to urban landscape waters―Shichaqianhai and Roma Lake, water quality and habitat raits of typical landscape waters in Beijing were analyzed. The differences of transparency in wo lakes were discussed. The results show that, transparency of Shichaqianhai arrives at 70 cm, nd that of Roma Lake is 27 cm, which is because of different phosphorous concentration in two andscape waters. Therefore, phosphorous concentration is a key factor to keep aquatic ecosystem ealth in urban landscape waters.

Hydrogen is a significant industrial raw material and clean fuel, and hydrogen separation has significant social and economic values. Membrane separation has a wide application prospect in hydrogen separation as it uses simple devices, is environmentally friendly, and has high conversion efficiency and low cost of investment. Hydrogen separation membranes remain a research focus as their performance is the major factor that determines hydrogen separation efficiency. This study summarized the application demand and basic mechanism of hydrogen separation membranes and reviewed the research progress of dense metal, porous inorganic, metal-organic framework (MOF), organic polymer, and hybrid matrix membranes. Specifically, although porous inorganic, organic polymer, and hybrid matrix membranes have good hydrogen separation and purification performances, their separation performance still requires improvement when they are applied in distributed and small application scenarios. Improving the anti-poisoning performance of palladium-based metal membranes and optimizing the cost-effectiveness are effective ways to promote industrial application of membranes. Combining the advantages of porous inorganic and MOF membranes can facilitate the significant development of molecular sieving membranes. The high-temperature resistance and mechanical properties of organic polymer membranes require improvement. Modifying existing polymer membrane materials and preparing polymer alloys are two major directions for developing novel gas separation membranes. The performance of hybrid matrix membrane can be notably improved after controllable adjustment of its distribution. The research and application of multiple membranes has supported hydrogen separation and purification, and these membrane techniques will continue creating more engineering values once the number of available materials is increased and the preparation technologies are advanced in the future.
