Water striders jump upwards from the water surface without breaking it. This study shows that they learn through personal experience, just like we do, to adjust leg movements to their body weight and to jump without breaking the water surface. Only females do that. A female water strider needs this skill to adjust locomotion to the change in her weight each time when a male rides on he back during mating.
EPFL engineers have developed a computer chip that combines two functions - logic operations and data storage - into a single architecture, paving the way to more efficient devices. Their technology is particularly promising for applications relying on artificial intelligence.
University of Rochester and Cornell University researchers create 'optically active spin arrays' within a device that could serve as a node for exchanging photons with distant locations.
The right indoor lighting can help set the mood, from a soft romantic glow to bright, stimulating colors. But some materials used for lighting, such as plastics, are not eco-friendly. Now, researchers reporting in ACS Nano have developed a bio-based, luminescent, water-resistant wood film that could someday be used as cover panels for lamps, displays and laser devices.
Carbon nanotube (CNT) forests are a solution to scaling up the production of CNTs, which are becoming a staple in many industries. However, even the best catalyst used to grow these forests deteriorates quickly, capping possible forest length at ~2 cm. Now, scientists from Japan have proposed a way to ensure longer catalyst lifetime and higher growth rate, creating a CNT forest that is a record seven times longer than any existing CNT array.
A team of scientists at Kanazawa University have shown how water-soluble tetraphenylethene molecules can become fluorescent when aggregating at a biomembrane-mimetic liquid-liquid interface. This work may lead to new optical molecular probes and smart vesicles for delivering pharmaceuticals directly to cells.
Scientists at Swansea University have developed a very sensitive method to detect the tiny signatures of so called 'charge traps' in organic semiconductors.
The University of Tokyo introduced a system of gold nanorods that acts like a tiny light-driven motor, with its direction of motion is determined by the orientation of the motors. This work may lead to smaller and more precise nanomachines.
Scientists at Osaka University show how to achieve a very strong nonlinear optical response in silicon nanostructures based on the photothermal effect. This work may lead to entirely optical control of logic gates in computers.
A thin coating of the 2D nanomaterial hexagonal boron nitride is the key ingredient in a cost-effective technology developed by Rice University engineers for desalinating industrial-strength brine.
