Summary: Hierarchically porous carbon microtubes (HPCMTs) derived from plane tree fruit fluff via self-activation method showed prominent supercapacitor performance due to their hierarchical pore structure, high specific surface area, and good wettability with electrolyte. The HPCMT-1100-6, with the largest SSA and maximal total pore volume, exhibited an ultrahigh energy density of 46.3 Wh/kg at high power density, as well as excellent rate capability and long-term cyclic stability. This study provides a sustainable strategy for converting biomass waste into high-valued porous carbons for high-energy-density supercapacitors.

Summary: Hierarchical coral spheres of CeO2/ZnO were prepared using a template-free hydrothermal method followed by annealing treatment. The resulting coral spheres exhibited superior acetone sensing, cycling stability, and long-term stability compared to CeO2 or ZnO. By controlling the Ce/Zn ratio, the coral spheres showed the highest response towards 100 ppm acetone at the optimum working temperature of 245°C, reaching up to 145, which was approximately 5.5 times higher than that of ZnO coral spheres. The enhanced gas sensing performance could be attributed to the well-dispersed and assembled CeO2 nanoparticles on the surface of ZnO coral spheres and the heterojunctions between CeO2 and ZnO, which generated abundant oxygen vacancies in the CeO2/ZnO coral spheres.

Summary: Polymeric membranes based on 2D molecular brushes with a soft-hard-soft hierarchical structure have been designed and fabricated to address the issue of lithium dendrite piercing at high current density. The rigid 2D aromatic structure of intralayer graphene oxide backbones provides a shield effect, which is further strengthened by layer-by-layer stacking of 2D molecular brushes. The interconnected interlayer channels and soft PSSLi side-chains allow rapid lithium-ion transportation and homogenize lithium-ion flux. The developed membranes enable long-term reversible lithium plating/striping at high current density.

The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
