Here, we report a novel approach for the bottom-up assembly of hierarchical building blocks: simple molecular blocks (MBBs) and resultant supermolecular (SBBs) to build highly coordinated nets. A specific network, (3,24)-connected rht, was used as blueprint construct metal-organic framework where MBBs/SBBs augment net.
Li-S rechargeable batteries are attractive for electric transportation because of their low cost, environmentally friendliness, and superior energy density. However, the system has yet to conquer marketplace, owing its drawbacks, namely, soluble polysulfide formation.

We find that enhanced binding molecular hydrogen in ion-exchanged anionic framework is largely governed by presence electrostatic field cavity, which reflected isosteric...

Abstract Latent cooling load accounts for 30% of the total air-conditioning, and its proportion is even higher in many tropical subtropical climates. Traditional vapour-compression air-conditioning (VCAC) has a low coefficient performance (COP) due to refrigeration dehumidification process, which often makes necessary great deal subsequent re-heating. Technologies using conventional desiccants or sorbents indoor moisture control are less competitive than VCAC their high regeneration...
