Driven by advanced nanomaterials and nanofabrication technologies, tremendous progress has been made over the last 15 years in making ultrathin membranes based on a variety of advanced nanomaterials and nanotechnologies. Further pushing membrane thickness to sub-50 nm or even atomic level is appealing to researchers, with the ultrafast permeance that may be enabled and ultimate understanding of formation and transport at the extremely low thickness that can be significantly different from ...
The quantum-mechanical exchange interaction between electrons can be specifically modified with intense infrared light fields on time scales of a few femtoseconds, as time-resolved experiments on sulfur hexafluoride molecules show. This finding lights a way for bottom-up controlling chemical reactions with lasers in the future - based purely on electrons, the 'glue' of chemistry.
Scientists searching for a scalable method to fabricate quantum dots have developed a way to recycle rice husks to create the first silicon quantum dot LED light. Their new method transforms agricultural waste into state-of-the-art light-emitting diodes in a low-cost, environmentally friendly way.
