Three Research Groups, Two Kinds of Electronic Properties, One Material
An outstanding collaboration combines materials science, experimental and theoretical physics. The work paves the way to new designed materials that combine in them multiple electrical functionalities. This is the story of a unique material - made of a single compound, it conducts electrons in different ways on its different surfaces and doesn't conduct at all in its middle.

MEET - Publication galvanic corrosion
In addition to high purchase costs and the still underdeveloped charging infrastructure, the limited range is one of the biggest obstacles to switching to electric vehicles. Industry and science are therefore working intensively on developing batteries with a higher energy density and making them suitable for series production.

Sensors woven into a shirt can monitor vital signs
Sensors woven into a shirt can monitor vital signs
MIT researchers have developed a way to incorporate electronic sensors into stretchy fabrics, allowing them to create shirts or other garments that could be used to monitor vital signs such as temperature, respiration, and heart rate. The sensor-embedded garments, which are machine washable, can be customized to fit close to the body of the person wearing them.

Cool down fast to advance quantum nanotechnology
Rapidly cooling magnon particles proves a surprisingly effective way to create an elusive quantum state of matter, called a Bose-Einstein condensate. The discovery can help advance quantum physics research and is a step towards the long-term goal of quantum computing at room temperature. An international team of scientists have found an easy way to trigger an unusual state of matter called a Bose-Einstein condensate.

Advance could enable remote control of soft robots
An applied magnetic field (in blue) can cause magnetized particles embedded in a soft material to rearrange themselves into new patterns. By harnessing this phenomenon, researchers can fine-tune the soft material's properties. Image courtesy Xin Zou, Grainger Institute for Engineering Soft materials, such as rubber or polymers that can endure drastic changes to their shape, are promising for applications where flexibility and shapeshifting abilities are paramount.

Seeing 'Under the Hood' in Batteries
Seeing ’Under the Hood’ in Batteries
From next-gen smartphones to longer-range electric cars and an improved power grid, better batteries are driving tech innovation. And to push batteries beyond their present-day performance, researchers want to see "under the hood" to learn how the individual ingredients of battery materials behave beneath the surface.

First sighting of mysterious Majorana fermion on a common metal
First sighting of mysterious Majorana fermion on a common metal
Physicists at MIT and elsewhere have observed evidence of Majorana fermions - particles that are theorized to also be their own antiparticle - on the surface of a common metal: gold. This is the first sighting of Majorana fermions on a platform that can potentially be scaled up. The results, published in the Proceedings of the National Academy of Sciences , are a major step toward isolating the particles as stable, error-proof qubits for quantum computing.

World's most complex microparticle: A synthetic that outdoes nature's intricacy
World’s most complex microparticle: A synthetic that outdoes nature’s intricacy
Synthetic microparticles more intricate than some of the most complicated ones found in nature have been produced by a University of Michigan-led international team. They also investigated how that intricacy arises and devised a way to measure it. The findings pave the way for more stable fluid-and-particle mixes, such as paints, and new ways to twist light-a prerequisite for holographic projectors.

A new lightsource for the chip industry
Photonic chips made possible by light-emitting silicon-germanium alloys For the past 50 years, researchers around the globe have been looking for a way to make lasers with silicon or germanium. A team from the Technical University of Eindhoven (TU/e) and the Technical University of Munich (TUM) has now succeeded in developing a light-emitting, silicon-germanium alloy.

Artificial fog helps lasers shine brighter
Artificial fog helps lasers shine brighter
Laser-based lights could replace lightbulbs thanks to an artificial 'fog' that scatters laser light, producing high brightness at low power. The new and improved laser-based lights could be used anywhere from indoor lighting and projectors to car headlights and outdoor floodlights. As they produce high brightness at low power, they would be more energy-efficient than regular lightbulbs or LEDs.

New Superconducting Film Resists a Magnet’s Power to Thwart It
To Joseph Falson , who recently joined Caltech as assistant professor of materials science, electrons are like exotic supercars because they possess amazing capabilities. Consider the phenomenon of superconductivity, in which paired electrons fly unimpeded, resulting in materials that display zero electrical resistance.

University of Birmingham mourns the passing of renowned economist Peter Sinclair
Scientists have developed a way of extracting a richer palette of colours from the available spectrum by harnessing disordered patterns inspired by nature that would typically be seen as black. Colours that we see in nature often come from nanoscale patterns that reflect light back in particular ways.

Technique reveals how crystals form on surfaces
DNA-based self-assembling system sheds light on processes essential for semiconductors and nanotechnology. The process of crystallization, in which atoms or molecules line up in orderly arrays like soldiers in formation, is the basis for many of the materials that define modern life, including the silicon in microchips and solar cells.

Mesoamerican copper smelting technology aided colonial weaponry
Mesoamerican copper smelting technology aided colonial weaponry
Spanish conquerors depended on indigenous expertise to keep up their munitions supplies, archaeologists have found. When Spanish invaders arrived in the Americas, they were generally able to subjugate the local peoples thanks, in part, to their superior weaponry and technology. But archeological evidence indicates that, in at least one crucial respect, the Spaniards were quite dependent on an older indigenous technology in parts of Mesoamerica (today's Mexico, Guatemala, Belize, and Honduras).

FACULTY Q&A Liang Qi , a professor of materials science and engineering at the University of Michigan, answered questions about his group's new paper in npj Computational Materials. What is elastic stiffness' Elastic and glass don't seem to be two words that go together. All solid materials, including glass, have a property called elastic stiffness-also known as elastic modulus.

Neural networks facilitate optimization in the search for new materials
Sorting through millions of possibilities, a search for battery materials delivered results in five weeks instead of 50 years. When searching through theoretical lists of possible new materials for particular applications, such as batteries or other energy-related devices, there are often millions of potential materials that could be considered, and multiple criteria that need to be met and optimized at once.
