Fogged up glasses, windscreens and bathroom mirrors may be a thing of the past.
Researchers have invented a new, permanent, multi-purpose coating technology that will prevent your spectacles, car windscreen or bathroom mirror fogging up ever again. The coating, called XeroCoat, also cuts out unwanted reflections from glass, letting more light through. Making it ideal for spectacles and improving the performance of solar cells and glasshouses.
University of Queensland physicists Michael Harvey and Paul Meredith developed this technology based upon thin films of nano-porous silica; this means that “the coating is a layer of glass full of tiny invisible bubbles, just like the foam on beer,” said Mr Harvey. “Because it’s made of glass it’s as hard as glass,” he said, giving the added benefit of a hard coating on items to prevent or reduce scratching. The whole production process is extremely simple, very low-cost and environmentally friendly. Queensland’s Sustainable Energy Innovation Fund, administered by the Environmental Protection Agency, recently awarded the team a grant to further develop the new coating.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
