Additive manufacturing based on direct laser writing two-photon polymerization facilitates the fabrication of microstructures with full 3D design freedom. Here, this technique is exploited for engineering scaffolds accurately mimicking shape and size three types human cells. The cell models employed in study were chosen to include a range dimensions different identifiable features highlight ver...

As an important energy carrier in terms of carbon neutrality, green hydrogen produced by water electrolysis using renewable electricity has attracted worldwide attention. The polymer electrolyte electrolyzer (PEWE) the potential to be a mainstay market future because its superior performance. However, development PEWE is constrained slow progress membrane electrode assembly (MEA), which essenti...

in this study the catalytic dehydrogenation of ethylbenzene to styrene was investigated in a simulated tubular sodalite membrane reactor. the high quality microporous sodalite membrane was synthesized by direct hydrothermal method and characterized by single gas permeation measurements. the performance of the prepared membrane showed high potential for application in a dehydrogenation membrane ...

Perfluorinated-sulfonic-acid-based ionomers (PFSAs) are still the material of choice for electrochemical energy devices such as proton-exchange membrane fuel cells or water electrolyzers. However, PFSAs show significant drawbacks ranging from a restricted temperature window operation due to insufficient thermomechanical stability, high cost, and questionable environmental properties. Recently, ...

The immunological potential of extracellular vesicles produced by Gram-negative bacteria, the so-called outer-membrane (OMVs), can be improved genetic engineering, resulting in containing multiple immunogens. this approach for development a vaccine candidate enteric fever was recently demonstrated Gasperini and colleagues.
