Novel mesoporous poly(vinyl alcohol)/SiO(2) composite nanofiber membranes functionalized with mercapto groups with diameters of 300-500 nm have been fabricated by a sol-gel electrospinning process; they were highly effective at absorbing Cu(ii) ions from waste water. These nanofiber membranes could be regenerated through acidification.

Polymeric nanoparticle is a general platform for drug delivery that has been receiving extensive attention in both academia and industry. With the ability to load drugs at high encapsulation efficiency, to release drugs at a sustained and controllable manner, and to be functionalized with targeting agents for cell-specific drug delivery, polymeric nanoparticle-based drug formulations show great...

The unique structural features and stealth properties of a recently developed red blood cell membrane-cloaked nanoparticle (RBC-NP) platform raise curiosity over the interfacial interactions between natural cellular membranes and polymeric nanoparticle substrates. Herein, several interfacial aspects of the RBC-NPs are examined, including completeness of membrane coverage, membrane sidedness upo...

The great potential of nanoporous membranes for water filtration and chemical separation has been challenged by the trade-off between selectivity and permeability. Here we report on nanoporous polymer membranes with an excellent balance between selectivity and permeability of ions. Our membranes are fabricated by irradiating 2-μm-thick polyethylene terephthalate Lumirror® films with GeV heavy i...

Polymer membranes are attractive for molecular-scale separations such as hydrogen purification because of inherently low energy requirements. However, membrane materials with outstanding hydrogen separation performance in feed streams containing high-pressure carbon dioxide and impurities such as hydrogen sulfide and water are not available. We report highly permeable, reverse-selective membran...
