Gravity driven separation of emulsified oil–water mixtures utilizing in situ polymerized superhydrophobic and superoleophilic nanofibrous membranes

Abstract: A novel and scalable strategy was developed for the synthesis of in situ polymerized superhydrophobic and superoleophilic nanofibrous membranes for effective separation of water-in-oil microemulsions, which exhibit an extremely high flux of 892 L m−2 h−1 solely driven by gravity, as well as good antifouling properties, thermal stability and durability

Pyrolyzed Bacterial Cellulose: A Versatile Support for Lithium Ion Battery Anode Materials

Abstract: A scalable, low-cost and environmentally benign strategy is developed for the facile construction of a unique kind of three-dimensional porous electrode architecture for high-performance lithium ion batteries. The methodology is based on the employment of pyrolyzed bacterial cellulose as a new three-dimensional porous scaffold to support various nanostructured active electrode materials, such as SnO and Ge.

Synergetic Transformations of Multiple Pollutants Driven by Cr(VI)–Sulfite Reactions

Abstract: Reduction of Cr(VI) is often deemed necessary to detoxify chromium contaminants; however, few investigations utilized this reaction for the purpose of treating other industrial wastewaters. Here a widely used Cr(VI)-sulfite reaction system was upgraded to simultaneously transform multiple pollutants, namely, the reduction of Cr(VI) and oxidation of sulfite and other organic/inorganic pollutants in an acidic solution. As(III) was selected as a probe pollutant to examine the oxidation capacity of a Cr(VI)-sulfite system. Both (•)OH and SO4(•-) were considered as the primary oxidants for As(III) oxidation, based on the results of electron spin resonance, fluorescence spectroscopy, and specific radicals quenching. As(III)-scavenging, oxidative radicals greatly accelerated Cr(VI) reduction and simultaneously consumed less sulfite. In comparison with a Cr(VI)-H2O2 system with 50 μM Cr(VI), Cr(VI), the sulfite system had excellent performance for both As(III) oxidation and Cr(VI) reduction at pH 3.5. Moreover, in this escalated process, less sulfite was required to reduce Cr(VI) than the traditional Cr(VI) reduction by sulfite process. This effectively improves the environmental compatibility of this Cr(VI) detoxification process, alleviating the potential for SO2 release and sulfate ion production in water. Generally, this study provides an excellent example of a "waste control by waste" strategy for the detoxification of multiple industrial pollutants.

Dendrimer-based nanodevices for targeted drug delivery applications.

Abstract: This review reports some recent advances on the use of dendrimers as a versatile platform for targeted drug delivery applications. The unique 3-dimensional architectures and macromolecular characteristics afford dendrimers with ideal drug delivery ability through encapsulating drugs in their interior or covalently conjugating drugs on their surfaces. The adaptable surface functionalization ability enables covalent conjugation of various targeting molecules onto the surface of dendrimers, thereby allowing for generation of various multifunctional nanodevices for targeted drug delivery applications. In particular, the application of dendrimers as versatile platforms for targeted cancer therapeutics will be introduced in detail.
