Mar 17, 2023 (Nanowerk News) Ice surfaces have a thin layer of water below its melting temperature of 0 °C. Such premelting phenomenon is important for skating and snowflake growth. Similarly, liquid often crystallizes into a thin layer of crystal on a flat substrate before reaching its freezing temperature, i.e....
New gene-editing technique reverses vision loss in mice
Mar 17, 2023 (Nanowerk News) Researchers in China have successfully restored the vision of mice with retinitis pigmentosa, one of the major causes of blindness in humans. The study, to be published in the Journal of Experimental Medicine ("Vision rescue via unconstrained in vivo prime editing in degenerating neural retinas"),...
Stalactites and stalagmites in the battery?
Mar 17, 2023 (Nanowerk News) They are considered the "Holy Grail" of battery research: so-called "solid-state batteries". They no longer have a liquid core, as is the case with today's batteries, but consist of a solid material. This leads to several advantages: Among other things, these batteries are more difficult...
Double-helix unzipping reveals DNA physics
Mar 17, 2023 (Nanowerk News) Reconstructing accurately how the parts of a complex molecular are held together knowing only how the molecule distorts and breaks up. This was the challenge taken on by a research team led by SISSA’s Cristian Micheletti and recently published on Physical Review Letters ("Nonequilibrium Thermodynamics...
Carbon nanotube films as ultrasensitive photodetectors: progress and challenges
Mar 17, 2023 (Nanowerk News) Ultrasensitive shortwave infrared photodetectors, which detect a subset of shortwave infrared light wavelengths outside of the visual spectrum, have many potential applications, including night surveillance, navigation during poor weather conditions, fiber optic communications and semiconductor quality control. Shortwave infrared photodetectors have traditionally been made out...
Crocodile skin inspires omnidirectionally stretchable pressure sensors
Mar 17, 2023 (Nanowerk News) The development of electronic skin with multiple senses is essential for various fields, including rehabilitation, healthcare, prosthetic limbs, and robotics. One of the key components of this technology is stretchable pressure sensors, which can detect various types of touch and pressure. Recently, a joint team...
Minimizing electric vehicles’ impact on the grid
Mar 17, 2023 (Nanowerk News) National and global plans to combat climate change include increasing the electrification of vehicles and the percentage of electricity generated from renewable sources. But some projections show that these trends might require costly new power plants to meet peak loads in the evening when cars...
Understanding how methanogenic bacteria ‘bio-mine’ minerals advances biotechnology
Mar 17, 2023 (Nanowerk News) Pyrite, also known as “fool’s gold,” is an abundant iron sulfide mineral in the Earth’s crust. All organisms need iron and sulfur to grow. Because pyrite does not dissolve in oxygen-free conditions, scientists previously thought that organisms could not use pyrite in the absence of...
New machine learning approach enables to identify One molecule in a billion molecules selectively with graphene sensors
Mar 16, 2023 (Nanowerk News) Graphene’s 2D nature, single molecule sensitivity, low noise, and high carrier concentration have generated a lot of interest in its application in gas sensors. However, due to its inherent non-selectivity, and huge p-doping in atmospheric air, its applications in gas sensing are often limited to...
3D-printed revolving devices can sense how they are moving
Mar 16, 2023 (Nanowerk News) Integrating sensors into rotational mechanisms could make it possible for engineers to build smart hinges that know when a door has been opened, or gears inside a motor that tell a mechanic how fast they are rotating. MIT engineers have now developed a way to...
