Under extreme impacts, metals get stronger when heated
The unexpected finding could be important for designing spacecraft shielding or in high-speed machining applications. Metals get softer when they are heated, which is how blacksmiths can form iron into complex shapes by heating it red hot. And anyone who compares a copper wire with a steel coat hanger will quickly discern that copper is much more pliable than steel.

Strings that can vibrate forever (kind of)
Researchers from TU Delft and Brown University have engineered string-like resonators capable of vibrating longer at ambient temperature than any previously known solid-state object - approaching what is currently only achievable near absolute zero temperatures. Their study, published in Nature Communications , pushes the edge of nanotechnology and machine learning to make some of the world's most sensitive mechanical sensors.

Detector for continuously monitoring toxic gases
The material could be made as a thin coating to analyze air quality in industrial or home settings over time. Most systems used to detect toxic gases in industrial or domestic settings can be used only once, or at best a few times. Now, researchers at MIT have developed a detector that could provide continuous monitoring for the presence of these gases, at low cost.

Electron vortices in graphene detected
Electron vortices in graphene detected
Researchers at ETH Zurich have, for the first time, made visible how electrons form vortices in a material at room temperature. Their experiment used a quantum sensing microscope with an extremely high resolution. When an ordinary electrical conductor - such as a metal wire - is connected to a battery, the electrons in the conductor are accelerated by the electric field created by the battery.

Solving physics puzzles with coloured dots
Solving physics puzzles with coloured dots
By analysing images made of coloured dots created by quantum simulators, researchers have studied a special kind of magnetism. In the future this method could also be used to solve other physics puzzles, for instance in superconductivity. Up close it looks like lots of coloured dots, but from a distance one sees a complex picture rich in detail: Using the technique of pointillism, in 1886 George Seurat created the masterpiece ,,A Sunday afternoon on the island of La Grande Jatte".

Groundbreaking Microcapacitors Could Power Chips of the Future
In the ongoing quest to make electronic devices ever smaller and more energy efficient, researchers want to bring energy storage directly onto microchips, reducing the losses incurred when power is transported between various device components. To be effective, on-chip energy storage must be able to store a large amount of energy in a very small space and deliver it quickly when needed - requirements that can't be met with existing technologies.

Leipzig physicists show that light can generate electricity even in translucent materials
Leipzig physicists show that light can generate electricity even in translucent materials
News from Some materials are transparent to light of a certain frequency. When such light is shone on them, electrical currents can still be generated, contrary to previous assumptions. Scientists from Leipzig University and Nanyang Technological University in Singapore have managed to prove this. "This opens new paradigms for constructing opto-electronic and photovoltaic devices, such as light amplifiers, sensors and solar cells," says Inti Sodemann Villadiego, Professor at the Institute of Theoretical Physics at Leipzig University.

Breakthrough in capacitor technology
Breakthrough in capacitor technology
Pacemakers, defibrillators, radar technology and electric vehicles all need electrical components called capacitors that can store and release a lot of energy in a matter of a few microseconds. Researchers at the University of Twente have recently found a way to increase these capacitors' storage, efficiency and durability.

A simple ’twist’ improves the engine of clean fuel generation
Researchers have found a way to super-charge the 'engine' of sustainable fuel generation - by giving the materials a little twist. The researchers, led by the University of Cambridge, are developing low-cost light-harvesting semiconductors that power devices for converting water into clean hydrogen fuel, using just the power of the sun.

Nanofibers rid water of hazardous dyes
Nanofibers rid water of hazardous dyes
Dyes, such as those used in the textile industry, are a major environmental problem. At TU Wien, efficient filters have now been developed - based on cellulose waste. Using waste to purify water may sound counterintuitive. But at TU Wien, this is exactly what has now been achieved: a special nanostructure has been developed to filter a widespread class of harmful dyes from water.

Breakthrough for battery production with sulphur cathodes
Electromobility and portable electronic devices such as laptops and cell phones are unthinkable without the use of lithium-ion batteries. The problem: highly toxic materials such as cobalt are often used for the cathodes of these batteries, which endanger the environment and the health of people in the countries where they are mined.

Mess is best: disordered structure of battery-like devices improves performance
The energy density of supercapacitors - battery-like devices that can charge in seconds or a few minutes - can be improved by increasing the 'messiness' of their internal structure. This could be a turning point for a field that's been stuck for a little while. Alex Forse Researchers led by the University of Cambridge used experimental and computer modelling techniques to study the porous carbon electrodes used in supercapacitors.

An ink for 3D-printing flexible devices without mechanical joints
Researchers are targeting the next generation of soft actuators and robots with an elastomer-based ink for 3D printing objects with locally changing mechanical properties, eliminating the need for cumbersome mechanical joints. For engineers working on soft robotics or wearable devices, keeping things light is a constant challenge: heavier materials require more energy to move around, and - in the case of wearables or prostheses - cause discomfort.
