Engineers develop highly efficient atmospheric water harvester with record-breaking clean water production

Jun 17, 2024 (Nanowerk Spotlight) Water scarcity is a growing global challenge, affecting two-thirds of the world's population to varying degrees. While atmospheric water harvesting has long been considered a potential solution, practical applications have been hindered by slow sorption kinetics (the rate at which water is absorbed), salt leakage,...

Chemical imaging more than just surface deep

Jun 17, 2024 (Nanowerk News) A new method in spectromicroscopy significantly improves the study of chemical reactions at the nanoscale, both on surfaces and inside layered materials. Scanning X-ray microscopy (SXM) at MAXYMUS beamline of BESSY II enables the investigation of chemical species adsorbed on the top layer (surface) or...

Strengthener for graphene

Jun 15, 2024 (Nanowerk News) Grapene's unusually high conductivity and favorable mechanical properties could further the development of flexible electronics, new batteries, and innovative composite materials for aeronautics and space flight. However, the development of elastic and tough films remains a challenge. In the journal Angewandte Chemie ("A Stretchable and...

Self-assembling and disassembling swarm molecular robots via DNA molecular controller

Jun 14, 2024 (Nanowerk News) Researchers from Tohoku University and Kyoto University have successfully developed a DNA-based molecular controller that autonomously directs the assembly and disassembly of molecular robots. This pioneering technology marks a significant step towards advanced autonomous molecular systems with potential applications in medicine and nanotechnology. Details of...

Artificial photosynthesis to produce hydrogen peroxide

Jun 14, 2024 (Nanowerk News) National University of Singapore (NUS) chemists have developed hexavalent photocatalytic covalent organic frameworks (COFs) which mimic natural photosynthesis for the production of hydrogen peroxide (H2O2), an important industrial chemical. The conventional method of H2O2 production involves using anthraquinone as a catalyst to convert air and...
