The assembly of molecular building blocks with metal ions generating microporous network solids has been the focus of intense activity. Because of their potential applications associated with channels and cavities, such materials have been examined for size- and shape-selective catalysis, separations, sensors, molecular recognition and nanoscale reactors. Within this context, assemblies of robu...

A Band N-doped microporous carbon has been synthesized via a substitution reaction. The obtained carbon exhibited much higher surface area than the previously reported Band N-doped carbon. The hydrogen storage measurements indicated that the Band N-doped microporous carbon had a 53% higher storage capacity than the carbon materials with similar surface areas. Furthermore, hydrogen storage via s...

Microporous metal–organic frameworks (MOFs), which are new types of zeolite analogues, have been paid extensive attention because of their potential applications in gas storage, separation, and catalysis. The modular construction of MOFs allows their pore size and shape to be systematically tuned by the judicious choice of metal-containing secondary building units (SBUs) and/or bridging linkers...

New membrane distillation configurations and a new membrane module were investigated to improve water desalination. The performances of three hydrophobic microporous membranes were evaluated under vacuum enhanced direct contact membrane distillation (DCMD) with a turbulent flow regime and with a feed water temperature of only 40 ◦C. The new configurations provide reduced temperature polarizatio...

Summary Anion-exchange membrane water electrolysis (AEMWE) suffers from low performance compared with mainstream techniques. Attempts at improvement have been confined to the development of membranes and electrodes. Here, in quest increasing AEMWE, a well-designed liquid/gas-diffusion layer (LGDL), termed as NiMPL-PTL, was developed by introducing nickel-based microporous layers (MPLs)...

PURPOSE Endoluminal application of mitomycin C shows promise as a nonsurgical approach to treating recalcitrant stricture but requires precise delivery to prevent mitomycin-mediated injury to adjacent normal mucosa. We describe a novel technique that uses a microporous polytetrafluoroethylene catheter balloon to endoluminally deliver mitomycin C to the target tissue while minimizing nontarget d...
