Feb 28, 2022 (Nanowerk News) Physicists at UC Santa Barbara have become the first to experimentally observe a quirky behavior of the quantum world: a “quantum boomerang” effect that occurs when particles in a disordered system are kicked out of their locations. Instead of landing elsewhere as one might expect,...
Lightweight nanofiber mats could battle bullets, deflect space debris
Feb 28, 2022 (Nanowerk News) University of Wisconsin–Madison engineers have created a nanofiber material that outperforms its widely used counterparts — including steel plates and Kevlar fabric — in protecting against high-speed projectile impacts. Basically, it’s better than bulletproof. “Our nanofiber mats exhibit protective properties that far surpass other material...
New, nature-inspired concepts for turning CO2 into clean fuels
Feb 28, 2022 (Nanowerk News) Researchers have developed an efficient concept to turn carbon dioxide into clean, sustainable fuels, without any unwanted by-products or waste. The researchers, from the University of Cambridge, have previously shown that biological catalysts, or enzymes, can produce fuels cleanly using renewable energy sources, but at...
Freshwater from thin air
Feb 28, 2022 (Nanowerk News) Hydrogels have an astonishing ability to swell and take on water. In daily life, they are used in dressings, nappies, and more to lock moisture away. A team of researchers has now found another use: quickly extracting large amounts of freshwater from air using a...
An expanded molecular alphabet for DNA data storage
Feb 28, 2022 (Nanowerk News) DNA data storage systems have the potential to hold orders of magnitude more information than existing systems of comparable size. Compared to existing data storage technologies, it is potentially less expensive, far more physically compact, more energy efficient, and longer lasting – DNA survives for...
How do material properties depend upon their dimensions? A dimension journey in the real world.
Feb 28, 2022 (Nanowerk News) Nanoparticles, for example, exhibit quite different properties from the bulk samples of the same materials. Yet nobody knows why. We discovered a control method of the fractal dimensions of any solid sample, enabling systematic and detailed examination of various physical properties of samples with different...
New optical tweezers put on the pressure to change color
Feb 28, 2022 (Nanowerk News) Scientists demonstrate an optical trapping technique using nanotextured black silicon that can efficiently trap polymer chains. By adjusting the laser intensity, these “optical tweezers” can control the florescence color emitted through a local concentration of a perylene-modified polymer solution. From a low intensity blue to...
A potential breakthrough for production of superior battery technology
Feb 28, 2022 (Nanowerk News) Micro supercapacitors could revolutionise the way we use batteries by increasing their lifespan and enabling extremely fast charging. Manufacturers of everything from smartphones to electric cars are therefore investing heavily into research and development of these electronic components. Now, researchers at Chalmers University of Technology,...
