This idea is part of the evolving science of precision agriculture, in which farmers use technology to target their use of water, fertilizer and other inputs. Precision farming makes agriculture more sustainable because it reduces waste.
Researchers aim to improve upconversion nanocrystals' composition and atomic structure to expand the library of bright and multicolor upconverters, while also generating fundamental understanding of light-matter interactions at the nanoscale.
A new rersearch report reveals a way to reduce the energy demand in one key step of the process for the polymerization of ethylene. It describes how a class of so-called Metal Organic Frameworks (MOFS) can effectively and selectively adsorb acetylene from the ethylene feedstock.
Scientists have developed a statistical method that obtains detailed descriptions of metal-molecule interfaces in single molecule junctions and verifies how molecular conformation can influence their performance. Their insights could help fine-tune the capabilities of nanoscale circuits.
Using atomic layer deposition, researchers deposited a thin film of nickel oxide onto a single crystal of titanium dioxide. Gold nanoparticles were introduced between the two layers to act like an antenna that harvests visible light.
By periodically jostling many individual atoms, researchers were able to shift an entire atomic cloud without any apparent overall motion by its constituents. The team is the first to test this predicted behavior, which arises in what they call a geometric charge pump.
Researchers have built a tabletop instrument that can perform measurements that were only previously possible at large national magnet labs. The measurements will help in the development of next generation electronic devices employing 2-D materials.
A breakthrough could make infra-red technology easy-to-use and cheap, potentially saving millions of dollars in defence and other areas using sensing devices, and boosting applications of technology to a host of new areas, such as agriculture.
In the minuscule world of nanotechnology, big steps are rare. But a recent development has the potential to massively improve our lives: an engine measuring 200 billionths of a metre, which could power tiny robots to fight diseases in living cells.
