Nano-sponge with extreme properties
Nano-sponge with extreme properties
A new process simplifies the fabrication of porous materials with a defined nanostructure and takes them one step closer to mass production. Materials with a defined nanostructure can have surprising properties. One example is a lightweight ceramic that springs back to its original shape, like a sponge, after being compressed.

Yellow is the new brown
Yellow is the new brown
If different types of vegetables and fruits are stored together, they influence each other's ripening process. This is due to ethylene, which is emitted by some plant-based foodstuff and accelerates ripening. To prevent excessive food waste due to accelerated ripening Empa and ETH Zurich researchers are developing a new catalyst that degrades ethylene into water and carbon dioxide.

UCLA-led research team produces most accurate 3D images of ’2D materials’
A UCLA-led research team has produced in unprecedented detail experimental three-dimensional maps of the atoms in a so-called 2D material — matter that isn't truly two-dimensional but is nearly flat because it's arranged in extremely thin layers, no more than a few atoms thick. Although 2D-materials-based technologies have not yet been widely used in commercial applications, the materials have been the subject of considerable research interest.

Dimming Betelgeuse likely isn't cold, just dusty
Dimming Betelgeuse likely isn’t cold, just dusty
Late last year, news broke that the star Betelgeuse was fading significantly, ultimately dropping to around 40% of its usual brightness. The activity fueled popular speculation that the red supergiant would soon explode as a massive supernova. But astronomers have more benign theories to explain the star's dimming behavior.

Bacteria killed by new light-activated coating
A new coating that activates in low intensity light to kill bacteria such as Staphylococcus aureus and Escherichia coli has been developed by a UCL-led team of researchers. To stop the spread of disease, it could be used to coat phone screens and keyboards, as well as the inside of catheters and breathing tubes, which are a major source of healthcare-associated infections (HCAIs).

Strange metal behavior in a pure ferromagnetic Kondo lattice
Strange metal behavior in a pure ferromagnetic Kondo lattice
In the quest to harness quantum mechanics for new kinds of materials and new kinds of technologies, physicists are turning to the study of 'quantum materials' where the effects of quantum mechanics give rise to new forms of collective behavior. Normal metals, such as copper, gold or aluminum are well understood in terms of the quantum mechanics of individual electrons, and their resistivity depends linearly on temperature due to scattering of electrons by the vibrations of the lattice of atoms.

World's smelliest fruit could charge your mobile phone
World’s smelliest fruit could charge your mobile phone
A University of Sydney researcher has developed a new method using the world's most repulsive smelling fruit. Turning durian waste into super-capacitors could "substantially reduce" the cost of energy storage and charge devices very quickly. Imagine if we could use naturally-grown products, like plants and fruit, to store the electricity that charges commonly used electronics, like mobile phones, tablets, laptops or even electric cars?

New optical system could lead to devices that can recognize objects instantly
A technology developed at the UCLA Samueli School of Engineering could one day make it possible to produce optical devices that can instantaneously recognize objects without additional computer processing. The technology could ultimately be useful for robots, autonomous vehicles and other applications.

Energy researchers invent error-free catalysts
A team of researchers from the University of Minnesota, University of Massachusetts Amherst, University of Delaware, and University of California Santa Barbara have invented oscillating catalyst technology that can accelerate chemical reactions without side reactions or chemical errors. The groundbreaking technology can be incorporated into hundreds of industrial chemical technologies to reduce waste by thousands of tons each year while improving the performance and cost-efficiency of materials production.

Probing microscopic wiggles in squishy materials
Probing microscopic wiggles in squishy materials
Technique could help improve design of soft materials to withstand jostling during transport or settling due to gravity. The term "colloidal gel" may not be a household name, but examples of these materials are everywhere in our daily lives, from toothpaste and shower gel to mayonnaise and yogurt. Colloidal gels are mixtures of particles suspended in fluid, and depending on how they are manipulated, these gels can flow like liquid or hold their shape like a solid.

Microstructures Self-Assemble into New Materials
New process for creating nanoarchitected materials takes them one step closer to mass production A new process developed at Caltech makes it possible for the first time to manufacture large quantities of materials whose structure is designed at a nanometer scale-the size of DNA's double helix. Pioneered by Caltech materials scientist Julia R. Greer , "nanoarchitected materials" exhibit unusual, often surprising properties-for example, exceptionally lightweight ceramics that spring back to their original shape, like a sponge, after being compressed.

New tools show a way forward for large-scale storage of renewable energy
A technique based on the principles of MRI and NMR has allowed researchers to observe not only how next-generation batteries for large-scale energy storage work, but also how they fail, which will assist in the development of strategies to extend battery lifetimes in support of the transition to a zero-carbon future.

Using light to put a twist on electrons
Using light to put a twist on electrons
Method with polarized light can create and measure nonsymmetrical states in a layered material. Some molecules, including most of the ones in living organisms, have shapes that can exist in two different mirror-image versions. The rightand left-handed versions can sometimes have different properties, such that only one of them carries out the molecule's functions.

A better way to build diamonds
A better way to build diamonds
With the right amount of pressure and surprisingly little heat, a substance found in fossil fuels can transform into pure diamond. It sounds like alchemy: take a clump of white dust, squeeze it in a diamond-studded pressure chamber, then blast it with a laser. Open the chamber and find a new microscopic speck of pure diamond inside.

Defects add color to quantum systems
Researchers are investigating light-emitting defects in materials that may someday form the basis of quantum-based technologies, such as quantum computers, quantum networks or engines that run on light. Once understood, these defects can become controllable features. In a future built on quantum technologies, planes and spaceships could be fueled by the momentum of light.
