A team from the US Department of Energy's Lawrence Berkeley National
Laboratory (Berkeley Lab) has created a 2D laser just one molecule thick that promises to make significant
advances in ultra-compact photonic components for the likes of quantum
computers and the next generation of optoelectronic devices.
Scientists at UC Berkeley have developed a foldable, incredibly thin invisibility cloak that can wrap around microscopic objects of any shape and make them undetectable in the visible spectrum. In its current form, the technology could be useful in optical computing or in shrouding secret microelectronic components from prying eyes, but according to the researchers involved, it could also be scaled up in size with relative ease.
Not content with using hybrid artificial photosynthesis to turn CO2 emissions into plastics and biofuel, researchers at the Lawrence Berkeley National Laboratory (Berkeley Lab) now claim to have produced an enhanced system that uses water and solar energy to generate hydrogen, which is in turn used to produce methane, the main element of natural gas, from carbon dioxide. Generating such gases from a renewable resource may one day help bolster, or even replace, fossil fuel resources extracted from dwindling sub-surface deposits.
electronics miniaturization heads towards a theoretical physical limit in the
tens of nanometers, new methods of manufacturing are required to produce
transistors, diodes, and other fundamental electronic components. In this vein, a new range of molecule-sized
devices have been created in the laboratory, though with varying results in
terms of efficiency and practicality. Now a group of researchers from Berkeley
Lab and Columbia University claims to have created the highest-performing,
single-molecule diode ever made, which is said to be 50 times better in
performance and efficiency than anything previously produced.
