This review article focuses on an assessment of the innovative Gas Separation Membrane Bioreactor (GS-MBR), which is an emerging technology because of its potential for in-situ biohydrogen production and separation. The GS-MBR, as a special membrane bioreactor, enriches CO2 directly from the headspace of the anaerobic H2 fermentation process. CO2 can be fed as a substrate to auxiliary photo-bioreactors to grow microalgae as a promising raw material for biocatalyzed, dark fermentative H2-evolution. Overall, these features make the GS-MBR worthy of study. To the best of the authors' knowledge, the GS-MBR has not been studied in detail to date; hence, a comprehensive review of this topic will be useful to the scientific community.

Over the recent decades, hyperbranched polymers have received much attention in both academic and industrial sphere. Due to their highly branched structure and multifunctionality, hyperbranched polymers exhibit unique chemical and physical properties. Many hyperbranched polymers have been prepared by one-step polymerization. The polymerizations can be divided into three categories: step-growth polycondensation of ABx monomers, selfcondensative vinyl polymerization of AB* monomers and branching ring-opening polymerization of hypothetical ABx monomers. This review highlights some examples of synthesis of the most important hyperbranched polymers. Special attention is paid to step-growth polycondensation of ABx-type monomers and to polycondensation of A2 and B3 monomers. Some properties of hyperbranched polymers and their potential applications are also described.
