Abstract ：
Cellulose and its derivatives have received much attention as green raw materials to prepare ultrafiltration membranes. However, the inferior performance (low rejection, poor anti-fouling etc.) hinders their development. To improve the preparation of cellulose based ultrafiltration membrane and its performance, in this study, we developed a facile strategy to fabricate cellulose acetate ultrafiltration membranes by adding methyl acetate (MAC, as a co-solvent) to N, N-dimethylacetamide (DMAc). The results show that the pore morphologies of the membrane can be regulated by adjusting the DMAc to MAC ratio. Under optimal conditions, the pure water flux can reach 188.0 L/m2h, with the BSA rejection ratio of 95.2 %, which is about 20 % higher than the control. Furthermore, the anti-fouling and long-term stability of ultrafiltration membranes have improved significantly. The above results support the conclusion that using a mixed solvent by adding MAC to DMAc is effective for tuning the pore structure of cellulose-based ultrafiltration membrane, hence, improving its performance for water purification.

Abstract ：
Membranes are the dominant material for seawater desalination and clean-water harvesting, which are commonly composed of synthetic polymers, showing low hydrophilicity and environmental hazard. Herein, we developed a low-cost, intrinsically green, superhigh-water flux Janus cellulose membrane (CEM) via a facile cellulase etching strategy. Coating cellulase on the single surface of cellulose membrane (such as top surface), triggers effective etching on its top section rather than bottom section, which architects an asymmetric-pore structure of the Janus CEM including porous top-and dense bottom-layer. Such distinction endows the Janus CEM with an unprecedented high-water flux of 135.75 LMH and a low salt-water ratio of 0.29 gmiddotL(-1) for 1 M NaCl solution, which is 17-time higher and 62-time lower than that of the pristine CEM. Our Janus CEM enables a promising participant for the advanced membrane materials toward versatile separation engineering.

Abstract ：
Forward osmosis (FO) technology exhibits great potential in seawater desalination and wastewater treatment due to its negligible energy consumption and high antifouling, however, the weak desalination capability, especially low water flux, remains challenging. Herein, a cost-effective and high-desalination-performance chitosan (CS)-based FO membrane is developed via coupling the electrospinning CS nanofibers and interfacial-polymerized polyamide (PA). The electrospun nanofibers construct the porous and hydrophilic CS layer with the large pore-diameter of similar to 274 nm and low thickness of-10 mu m, enabling the effective transport of water molecules, specifically, a superhigh water flux of 107.53 LMH at a low salt-water ratio of 0.24 g center dot L-1. In addition, such superior desalination performance of the as-prepared FO membrane is universal for the various salt species and concentrations. Our CS nanofiber-based membrane with the high separation capability of water-salt, desirable antibacterial activity, as well as the low cost, offers a roadmap toward the sustainable membrane materials.

采用高温固相法制备钇钡铜氧(YBCO),研磨后超声分散在无水乙醇中得纳米YBCO/乙醇溶胶,再分别掺入苯胺和邻苯二胺,浓缩后真空干燥得有机物/YBCO杂化材料。采用傅里叶红外光谱(FT-IR)、X射线衍射(XRD)、X射线光电子能谱(XPS)和振动样品磁强计(VSM)研究了有机物对YBCO化学组成、物相、元素价态和磁性性能的影响。结果表明,掺入0.05%～5%(质量分数,下同)范围内的苯胺、邻苯二胺不影响YBCO的红外吸收,但显著提高了其XRD衍射峰的强度。两种杂化材料中N-Y之间的相互作用比N-Ba或N-Cu强烈,N元素含量对杂化材料中YBCO的超导转变温度T_c和磁化强度M有显著影响,N元素含量超过1%,T_c明显降低,M_(min)则相应提高。

Abstract ：
Bamboo dissolving pulp (BP)/chitosan (CS) blend solutions were obtained by adding different weight ratios of BP and CS particles to N-methylmorpholine-N-oxide (NMMO) solvent. The processing and membrane forming performances of the blend solutions were studied using a rotating rheometer. The BP/CS blend solutions' optimal processing temperature was 50 to 70 degrees C. When the CS weight ratio was 9.09 wt%, the viscosity of the solution decreased, which was conducive to the processing of the membrane. The BP/CS blend ultrafiltration membranes were prepared by phase transformation of the blend solutions. The results showed that the rejection rate of the BP/CS blend ultrafiltration membrane with physically added CS particles was greatly improved compared with that of the regenerated BP ultrafiltration membrane.
