Solar‐driven interfacial evaporation is a potential water purification solution. Here, a novel regenerable hydrogel interfacial evaporator is designed with tunable water production. Such an evaporator is fabricated by readily mixing hydroxypropyl chitosan (HPCS) and dibenzaldehyde‐functional poly(ethylene glycol) (DF‐PEG) at ambient conditions. Dynamic Schiff base bonds bestow on the HPCS/DF‐PEG hydrogel...
Lithium metal batteries (LMBs) are promising for next‐generation high‐energy‐density batteries owing to the highest specific capacity and the lowest potential of Li metal anode. However, the LMBs are normally confronted with drastic capacity fading under extremely cold conditions mainly due to the freezing issue and sluggish Li+ desolvation process in commercial ethylene carbonate (EC)‐based electrolyte...
In article number 1905987, Na Liu and co‐workers demonstrate the hierarchical assembly of DNA origami catenanes templated by gold nanoparticles. Catenanes containing two, three and four rings are successfully created. By releasing the gold nanoparticles, the rings within the origami catenanes can be set free. This work will enrich the toolbox of DNA‐based functional nanodevices with programmable and...
Mechanically interlocked molecules have marked a breakthrough in the field of topological chemistry and boosted the vigorous development of molecular machinery. As an archetypal example of the interlocked molecules, catenanes comprise macrocycles that are threaded through one another like links in a chain. Inspired by the transition metal–templated approach of catenanes synthesis, the hierarchical...
In article number 1702990, Peer Fischer, Frank Neubrech, Na Liu, and co‐workers fabricate three‐dimensional palladium helices by nanoglancing angle deposition exhibiting strong circular dichroism for sensitive hydrogen detection in the flammable range. The linearity of the sensor response is significantly improved using palladiumgold hybrid helices. Such a chiral plasmonic sensor scheme is of potential...
In this article, a chiral plasmonic hydrogen‐sensing platform using palladium‐based nanohelices is demonstrated. Such 3D chiral nanostructures fabricated by nanoglancing angle deposition exhibit strong circular dichroism both experimentally and theoretically. The chiroptical properties of the palladium nanohelices are altered upon hydrogen uptake and sensitively depend on the hydrogen concentration...
