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.

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.

Fur-friendly ’wearable for pets’ developed at Imperial
Imperial College researchers London have invented a new health tracking sensor for pets and people that monitors vital signs through fur or clothing Our stretchy, flexible invention heralds a whole new type of sensor that can track the health of animals and humans alike over fur or clothing. Dr Firat Guder Department of Bioengineering The new type of sensor, which can detect vital signs like heart and breathing rates through fur and up to four layers of clothing, could help make everyday wearables for pets and livestock a reality.

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.

Short film of a magnetic nano-vortex
Short film of a magnetic nano-vortex
For the first time, researchers at the Paul Scherrer Institute PSI have recorded a "3D film" of magnetic processes on the nanometer scale. This reveals a variety of dynamics inside the material, including the motion of swirling boundaries between different magnetic domains. The insights were gained with a method newly developed at the Swiss Light Source SLS.

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.

Intensified research in concrete and asphalt
As of March 2020, the new "Concrete and Asphalt" lab will strengthen Empa's research in the field of building materials. Innovative technologies and materials for sustainable production and use are particularly in demand in these areas, as these two building materials, with an annual volume of more than 4.5 billion tonnes, account for the largest proportion of all materials used worldwide by far.

How much carbon is buried deep within Earth? New simulation provides clues
Understanding Earth's carbon cycle has important implications for understanding climate change and the health of biospheres. But scientists don't yet understand how much carbon lies deep in Earth's water reservoirs-for example, in water that is under extreme pressure in the mantle-because experiments are difficult to conduct under such conditions.

Our memory prefers essence over form
Our memory prefers essence over form
Researchers from the University of Geneva and CY Cergy Paris University have shown that current situations conjure up past situations that share deep, structural, similarities. What clues does our memory use to connect a current situation to a situation from the past? The results of a study conducted by researchers from the University of Geneva , Switzerland, - working in collaboration with CY Cergy Paris University in France - contrast sharply with the explanations found until now in the existing literature.

A fast light detector made of two-dimensional materials
Two research groups at ETH Zurich have joined forces to develop a novel light detector. It consists of two-dimensional layers of different materials that are coupled to a silicon optical waveguide. In the future, this approach can also be used to make LEDs and optical modulators. Fast and highly efficient modulators as well as detectors for light are the core components of data transmission through fibre optic cables.
