发布时间：2022-09-18 - 摘要：In the past decades ion exchange and adsorption resins have been emerging as highly effective alternatives to activated carbon for pollutants removal and subsequent recovery from industrial effluents. More recently, the development of polymer-based hybrid adsorbents (e. g.,nanocomposite adsorption resin and magnetic resin) have opened up new opportunities of their application in deep removal of pollutants (e. g.,toxic metals, phosphate,effluent organic matter) from waters. The present review focuses on preparation of these polymeric adsorbents, their physicochemical properties, adsorption characteristics and mechanism, as well as their application in water purification.关键词：Ion exchange resin;Adsorption resin;Wastewater treatment;Resource reuse

Once misfolding and abnormal aggregation, proteins will not only lose their biological activity,but also lead to a number of serious diseases, such as Alzheimer's disease,Parkinson's disease, Huntington's disease and some types of cancers,which are terrible threaten to human life and health. Therefore, how to effectively regulate protein folding has become one of the most challenging problems in life sciences. On the basis of a brief introduction of protein folding mechanism, we reviewed the recent progress in the development of protein folding control strategy, discussed the methods based on nanomaterials in detail and finally proposed the development trend of this field.关键词：Protein folding;Protein aggregation;Molecular chaperone;Nanomaterials

发布时间：2022-09-18 - 摘要：The demand for uranium stock has increased continuously in recent years due to the development of nuclear energy industry. The uranium resources on the earth mainly include the land mines and soluble uranium salts in the water system,such as the salt lakes and oceans. If the latter part of uranium could be properly extracted and utilized,the sustainability of nuclear energy industry can be remarkably enhanced. Additionally, suitable methods are necessarily developed to remove the hazardous uranium wastes and recycle the waste water produced by the nuclear plants. The solutions of both above issues are related to developing highly efficient uranium adsorption materials applicable in aqueous solutions. Amongst all adsorption materials reported so far,polymers attract great attention. As one of the most important types of materials,polymers materials have been tested in the real sea water and shown promising results. With the increasing research efforts invested into the field, polymers with high uranium adsorption capacity and selectivity as well as optimal recyclability are likely to emerge soon and make feasible the utilization of nuclear resources in the natural water system.关键词：Uranium;Uranyl ion;Chemisorption;Polymer materials

发布时间：2022-09-18 - 摘要：Poly(butylene succinate) (PBS) and its copolymers, a type of completely biodegradable materials with good comprehensive properties and outstanding processability, have been industrialized and found wide applications. In this article, the progress of synthesis, modification, characterization of structure and properties as well as industrialization in our lab is summarized. We have synthesized PBS with high molecular weight via melt poly-condensation using specially designed catalyst. The crystallization behavior, physical and mechanical properties, and biodegradation rate are tuned via molecular design, such as random copolymerization and chain branching. Based on the concept of configuration (conformation) match, we designed poly (butylene succinate-co-butylene fumarate) showing isomorphism in the whole composition range. Poly (butylene fumarate) was found to be a highly efficient polymeric nucleating agent for PBS. In addition, blending and nanocomposites can considerably improve the mechanical properties of PBS via controlling the phase structure and polymer matrix/nano-filler interaction. Based on the fundamental research, we collaborated with companies to build facilities capable of producing PBS and its copolymers in a scale of 10000 tons annually. The resins have been used for extrusion, injection molding, thermoforming and film blowing. The products have found applications as supermarket bags and biodegradable mulch films, etc.关键词：Poly(butylene succinate);Completely biodegradable materials;Copolymerization;Crystallization;Industrialization

Because of the facial amphiphilicity of cholic acid,various oligomers derived from cholic acid (molecular pockets, linear oligomers,cyclic oligomers) can form hydrophobic or hydrophilic cavities under the influence of external environment. These cholic acid derived oligomers could act as supramolecular hosts and coordinate with guest molecules,therefore these oligomers are promising materials in many fields such as chemosensor for heavy metal ions and lipid membrane transporters.关键词：Cholic acid;Amphiphilic;Molecular pockets;Linear oligomers;Cyclic oligomers
