Electromagnetic Fields of Nanostructures Visualized in 3D for the First Time
Electromagnetic Fields of Nanostructures Visualized in 3D for the First Time
Researchers at TU Graz and the University of Graz, together with experts from France, have succeeded in imaging surface phonons in 3D for the first time. This success could accelerate the development of new, efficient nanotechnologies. Whether for microscopy, data storage or sensor technology, many advanced technological applications that require specific functions rely on the structure of the electromagnetic field near the surfaces of materials.

First closeups of how a lithium-metal electrode ages
Scientists have documented a process that makes these next-gen batteries lose charge - and eventually some of their capacity for storing energy - even when a device is turned off. The same process that drains the battery of your cell phone even when it's turned off is even more of a problem for lithium-metal batteries, which are being developed for the next generation of smaller, lighter electronic devices, far-ranging electric vehicles and other uses.

Knitting roads
Knitting roads
Empa scientists are investigating how roads could be reinforced with simple means and recycled easily after use. Their tools are a robot and a few meters of string. A robotic arm lays out a string in a mandala-like pattern on a bed of gravel. What appears to be a contemporary art performance is basic research that explores new ways in road construction.

Recyclable ’veggie’ battery could power future devices
A new type of 3D-printed battery which uses electrodes made from vegetable starch and carbon nanotubes could provide mobile devices with a more environmentally-friendly, higher-capacity source of power. A team of engineers led from the University of Glasgow have developed the battery in a bid to make more sustainable lithium-ion batteries capable of storing and delivering power more efficiently.

The invisible keyhole
The invisible keyhole
Hard times for burglars and safecrackers: Empa researchers have developed an invisible "keyhole" made of printed, transparent electronics. Only authorized persons know where to enter the access code. At first glance, Empa researcher Evgeniia Gilshtein's idea seems inconspicuous - or more precisely, invisible.

Teamwork makes light shine ever brighter
Teamwork makes light shine ever brighter
Combined energy sources return a burst of photons from plasmonic gold nanogaps If you're looking for one technique to maximize photon output from plasmons , stop. It takes two to wrangle. Rice University physicists came across a phenomenon that boosts the light from a nanoscale device more than 1,000 times greater than they anticipated.

Research examines how to improve the measurement of the surface viscosity of filaments and membranes
Researchers at the Universidad Carlos III de Madrid (UC3M) have published a scientific paper that lays the foundation for developing a more precise method of measuring surface viscosity in liquid filaments and biological membranes with viscous surfaces. This development could be applied in the food, pharmaceutical or biomedical industries.

Voltage from wood
Voltage from wood
Researchers at ETH Zurich and Empa have chemically modified wood and made it more compressible, turning it into a mini-generator. When compressed, it generates an electrical voltage. Such wood could serve as a biosensor or as a building material that harvests energy. As Ingo Burgert and his team at ETH Zurich and Empa have proven time and again: wood is so much more than just a building material.

How do good metals go bad?
How do good metals go bad?
New measurements have solved a mystery in solid state physics: How is it that certain metals do not seem to adhere to the valid rules? We all have a clear picture in mind when we think of metals: We think of solid, unbreakable objects that conduct electricity and exhibit a typical metallic sheen. The behaviour of classical metals, for example their electrical conductivity, can be explained with well-known, well-tested physical theories.

Voltage from the parquet
Voltage from the parquet
Researchers at Empa and ETH Zurich have made wood compressible and turned it into a micro-generator. When it is loaded, an electrical voltage is generated. In this way, the wood can serve as a bio-sensor - or generate usable energy. The latest highlight: To ensure that the process does not require aggressive chemicals, naturally occurring wood-degrading fungi take over the task of modifying the wood.

Start small to answer big questions about photosynthesis
Start small to answer big questions about photosynthesis
New scientific techniques are revealing the intricate role that proteins play in photosynthesis. Despite being discovered almost 300 years ago, photosynthesis still holds many unanswered questions for science, particularly the way proteins organise themselves to convert sunlight into chemical energy and, at the same time, protect plants from too much sunlight.

Researchers use sound to shape the future of printing
Researchers use sound to shape the future of printing
Researchers have developed a way to coax microscopic particles and droplets into precise patterns by harnessing the power of sound in air. The implications for printing, especially in the fields of medicine and electronics, are far-reaching. The scientists from the Universities of Bristol and Bath have shown that it's possible to create precise, pre-determined patterns on surfaces from aerosol droplets or particles, using computer-controlled ultrasound.

Life’s rich pattern: Researchers use sound to shape the future of printing
Researchers have found a way to coax particles and droplets into precise patterns using the power of sound. The implications for printing are far-reaching. Last updated on Thursday 4 March 2021 Researchers have developed a way to coax microscopic particles and droplets into precise patterns by harnessing the power of sound in air.

Energy house-keeping
Energy house-keeping
Energy management in a house with a solar system is becoming increasingly complex: When do I turn on the heating so that it is nice and cosy in the evening? How much electricity can the hot water tank hold? Will there still be enough energy for the electric car? Artificial Intelligence (AI) can help solve the problem: Researchers at Empa developed an AI control system that can learn all these tasks - and save more than 25 percent energy in the process.

New facility at University of Birmingham accelerates battery recycling research
Researchers working on the Faraday Institution ReLiB (Recycling and Reuse of Li-ion Batteries) project have completed the installation of new battery testing and storage facilities at the University of Birmingham. The new facilities will allow battery scientists and engineers to speed up their research to develop safe, economic and environmentally sound recycling routes that recover large volumes of valuable materials contained in batteries at the end of their first life.

Graphene filter makes carbon capture more efficient and cheaper
Graphene filter makes carbon capture more efficient and cheaper
Chemical engineers at EPFL have developed a graphene filter for carbon capture that surpasses the efficiency of commercial capture technologies, and can reduce the cost carbon capture down to $30 per ton of carbon dioxide. One of the main culprits of global warming is the vast amount of carbon dioxide pumped out into the atmosphere mostly from burning fossil fuels and the production of steel and cement.

Microchips of the Future: Suitable Insulators are Still Missing
Until now, hexagonal boron nitride was considered the insulator of choice for miniaturised transistors. New investigations by TU Wien (Vienna) show: this may not be the way to go. For decades, there has been a trend in microelectronics towards ever smaller and more compact transistors. 2D materials such as graphene are seen as a beacon of hope here: they are the thinnest material layers that can possibly exist, consisting of only one or a few atomic layers.
