Quantum information gets a boost from thin-film breakthrough
Quantum information gets a boost from thin-film breakthrough
Method opens new path to all-optical quantum computers, other technologies Efficiently controlling certain thin-film materials so they emit single photons at precise locations-what's known as deterministic quantum emission-paves the way for beyond-lab-scale quantum materials. Michael Pettes LOS ALAMOS, N.M., May 29, 2019-Efforts to create reliable light-based quantum computing, quantum key distribution for cybersecurity, and other technologies got a boost from a new study demonstrating an innovative method for creating thin films to control the emission of single photons.

Experts develop nanolasers on silicon
Researchers at Cardiff University have shown tiny light-emitting nanolasers less than a tenth of the size of the width of a human hair can be integrated into silicon chip design. The photonic band-edge lasers can operate at superfast speeds and have the potential to help the global electronics industry deliver a range of new applications - from optical computing to remote sensing and heat seeking, Professor Diana Huffaker is Scientific Director of Cardiff University's Institute for Compound Semiconductors , based at Cardiff University's School of Physics and Astronomy.

Desired deformation
Since last week there is a unique wooden building in the Remstal near Stuttgart: a tower made of self-formed spruce boards. The method, which has been developed at Empa and ETH Zurich, uses the natural swelling and shrinking of wood under the influence of moisture and thus enables a new and unexpected architecture for the construction with the renewable and sustainable resource of wood.

Europe to Mars - and back!
Europe to Mars - and back!
27 May 2019 Europe has been in orbit around Mars for more than 15 years and is almost a year away from launching its first rover mission, but ambitions are already running high to go one step further: returning a sample from the Red Planet. Has there ever been life on Mars' Reconstructing the history of our neighbouring planet and understanding how its evolution diverged from that of Earth is at the heart of Mars exploration missions.

Origami-inspired materials could soften the blow for reusable spacecraft
Origami-inspired materials could soften the blow for reusable spacecraft
Space vehicles like SpaceX's Falcon 9 are designed to be reusable. But this means that, like Olympic gymnasts hoping for a gold medal, they have to stick their landings. Landing is stressful on a rocket's legs because they must handle the force from the impact with the landing pad. One way to combat this is to build legs out of materials that absorb some of the force and soften the blow.

Researchers Create Soft, Flexible Materials with Enhanced Properties
A team of polymer chemists and engineers from Carnegie Mellon University have developed a new methodology that can be used to create a class of stretchable polymer composites with enhanced electrical and thermal properties. These materials are promising candidates for use in soft robotics, self-healing electronics and medical devices.

Producing electricity at estuaries using light and osmosis
Producing electricity at estuaries using light and osmosis
Researchers at EPFL are working on a technology to exploit osmotic energy - a source of power that's naturally available at estuaries, where fresh water comes into contact with seawater. In a laboratory experiment, the team reproduced the real-world conditions that occur where rivers meet the sea (pH and salt concentration) and showed that, by shining light on a system comprising salt, water and a membrane three atoms thick, it was possible to optimize electricity production.

New Boost for ToCoTronics
New Boost for ToCoTronics
05/23/2019 A great success for Würzburg's physics department: its Collaborative Research Centre was rated as excellent and is now entering its second funding phase. The German Research Foundation is providing 12 million euros for this purpose. In 2015, physicists at Julius-Maximilians-Universität (JMU) Würzburg in Bavaria, Germany, succeeded in establishing a new Collaborative Research Centre in Würzburg.

Washable, wearable battery-like devices could be woven directly into clothes
Washable, wearable battery-like devices could be woven directly into clothes
Researchers have developed washable, wearable 'batteries' based on cheap, safe and environmentally friendly inks and woven directly into fabrics. The devices could be used for flexible circuits, healthcare monitoring, energy conversion, and other applications. The team, led by Dr Felice Torrisi , who recently joined Imperial from the University of Cambridge, have shown how graphene - an atom-thick sheet of carbon - and other related materials can be directly incorporated into fabrics.

Microplastics in freshwaters
Microplastics in freshwaters
Sea birds dying in agony with a belly full of plastic garbage; plastic accumulations as big as islands: Virtually everyone has seen pictures like these today. But there are also plastic particles that are barely visible to the eye - microplastics. The danger posed by these tiny particles has hardly been researched to date.

Building-integrated photovoltaics: aesthetic, efficient and widely accepted
Building-integrated photovoltaics: aesthetic, efficient and widely accepted
Within the scope of National Research Programme "Energy Turnaround" (NRP 70), researchers studied photovoltaic systems integrated into the roofs and façades (BIPV) of existing buildings from the point of view of aesthetic, ecological and economic criteria. Their findings: all developers and architects could use this technology for the renovation of existing buildings.

Design meets research
Design meets research
In the planned project "Re-FREAM" designers develop new and innovative fashion concepts in cooperation with researchers from all over Europe and completely rethink processes, traditions, production methods as well as design and functionality of clothing. Empa is also involved as a research partner. "We live in the most exciting era of mankind", write the initiators of the "Re-FREAM" project on their website.

New material also reveals new quasiparticles
New material also reveals new quasiparticles
Researchers at PSI have investigated a novel crystalline material that exhibits electronic properties that have never been seen before. It is a crystal of aluminum and platinum atoms arranged in a special way. In the symmetrically repeating unit cells of this crystal, individual atoms were offset from each other in such a way that they - as connected in the mind's eye - followed the shape of a spiral staircase.

Plastic Gets a Do-Over: Breakthrough Discovery Recycles Plastic From the Inside Out
Plastic Gets a Do-Over: Breakthrough Discovery Recycles Plastic From the Inside Out
Scientists from Berkeley Lab have made a next-generation plastic that can be recycled again and again into new materials of any color, shape, or form Light yet sturdy, plastic is great - until you no longer need it. Because plastics contain various additives, like dyes, fillers, or flame retardants, very few plastics can be recycled without loss in performance or aesthetics.

Watching concrete explode
Watching concrete explode
Even if concrete is not flammable, it can be hazardous in tunnel fires: high-performance concrete can explode at high temperatures. Although the phenomenon is well known, the physics behind it have not yet been fully understood. Empa researchers have now made the processes inside concrete visible for the first time using real-time-neutron radiography and tomography.
