Printing complex cellulose-based objects
Printing complex cellulose-based objects
Researchers from ETH Zurich and the Swiss Federal Laboratories for Materials Science and Technology (Empa) have set a new world record: they 3D printed complex objects with higher cellulose content than that of any other additively manufactured cellulose-based parts. To achieve this, they used a clever trick.

Activating palladium catalysis by light: teaching an old transition metal new tricks
Activating palladium catalysis by light: teaching an old transition metal new tricks
In the production of compounds, chemists have the fundamental goal of finding strategies that are most selective and avoid waste products. Breakthroughs in this area serve, among other things, to drive industrial innovation and drug development. In this context, allylic substitution reactions using catalysts made of so-called transition metals have already led to significant advances in science.

The growth of an organism rides on a pattern of waves
The growth of an organism rides on a pattern of waves
Study shows ripples across a newly fertilized egg are similar to other systems, from ocean and atmospheric circulations to quantum fluids. When an egg cell of almost any sexually reproducing species is fertilized, it sets off a series of waves that ripple across the egg's surface. These waves are produced by billions of activated proteins that surge through the egg's membrane like streams of tiny burrowing sentinels, signaling the egg to start dividing, folding, and dividing again, to form the first cellular seeds of an organism.

How to get conductive gels to stick when wet
How to get conductive gels to stick when wet
A new way of making polymers adhere to surfaces may enable better biomedical sensors and implants. But there has been a sticking point preventing their widespread use: their inability to adhere to a surface such as a sensor or microchip, and stay put despite moisture from the body. Now, researchers at MIT have come up with a way of getting conductive polymer gels to adhere to wet surfaces.

Deep learning for mechanical property evaluation
New technique allows for more precise measurements of deformation characteristics using nanoindentation tools. A standard method for testing some of the mechanical properties of materials is to poke them with a sharp point. This "indentation technique" can provide detailed measurements of how the material responds to the point's force, as a function of its penetration depth.

Puzzle about nitrogen solved thanks to cometary analogues
Puzzle about nitrogen solved thanks to cometary analogues
One of the basic building blocks of life is nitrogen. An international consortium was able to detect ammonium salt containing nitrogen on the cometary surface of Chury thanks to a method using analogues for comet material. The method on which the study on the detection of ammonium salt is based was developed at the University of Bern.

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).

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?

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.

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.

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.
