Photovoltaic perovskites can detect neutrons
Photovoltaic perovskites can detect neutrons
A simple and cheap device for detecting neutrons has been developed by a team of researchers and their collaborators. The device, based on a special class of crystalline compounds called perovskites, could be used to quickly detect neutrons coming from radioactive materials, e.g. a nuclear reactor that has been damaged or that is being transported nefariously, the researchers say.

Bilayer borophene is a first
Rice theories, Northwestern experiments combine to produce exotic material If one layer of borophene is good, will two be better? Scientists at Rice University and Northwestern University hope so, because they've now made the elusive material. Borophene is a one-atom-thick material made of boron atoms, which mostly fall together in neat triangles when grown in a furnace on a proper substrate.

Comet Supercomputer Used to Illustrate Methane Storage Applications
New findings could lead to carbon-neutral chemical fuels for vehicles Porous carbon is a well-established class of materials with significant potential in wide-ranging applications - from water purification and gas separation to energy storage devices and thermal insulation. A class of first-year graduate students is also full of potential - especially if those among them have already been part of an international research team whose work could impact technology needed for reduced-carbon or carbon-free chemical fuels for vehicles.

LED Material Shines Under Strain
LED Material Shines Under Strain
Berkeley Lab researchers devise a simple tactic to increase the efficiency of LED devices Smartphones, laptops, and lighting applications rely on light-emitting diodes (LEDs) to shine bright. But the brighter these LED technologies shine, the more inefficient they become, releasing more energy as heat instead of light.

Climate benefits vs. burdens: Which products are best suited for emerging carbon capture technologies?
Pulling heat-trapping carbon dioxide out of the air and turning it into useful products, a concept called carbon capture and utilization, has the potential to offer both environmental and economic benefits. By some optimistic estimates, CCU could generate annual revenues of more than $800 billion by 2030 while reducing climate-altering carbon dioxide emissions by up to 15%.

Phosphorescent material inspired by 'glow in the dark' wood
Phosphorescent material inspired by ’glow in the dark’ wood
Researchers have developed a new phosphorescent material from lignin, a major component of wood. Last updated on Wednesday 25 August 2021 Scientists have harnessed the natural ability of wood to faintly glow to develop a new sustainable phosphorescent material that could potentially be used in a wide number of applications, from medical imaging and optical sensing to 'glow in the dark' dyes and paints.

Changes in colour indicate deformations
Changes in colour indicate deformations
Researchers have developed a new type of laminate that changes colour as soon as the material is deformed. This way, the materials researchers can kill two birds with one stone: a lightweight composite material that inspects itself. Lightweight construction has found its way into many areas, especially automotive manufacturing, shipbuilding and aircraft construction.

Tantalizing Tantalum Actuators and Sensors
Carnegie Mellon University Accelerometers in mobile phones, microprocessors in laptops, and gyroscopes that balance drones each rely on microelectromechanical systems, or MEMS for short. Within these small systems are even smaller devices, called actuators and sensors, that perform various physical functions.

Band-aid for internal wounds
Band-aid for internal wounds
Closing wounds in the digestive tract is a challenge. researchers have now developed a polymer patch for the intestine that can be used to stably bond and seal internal injuries. A burst appendix or a life-threatening intestinal volvulus are emergencies that need to be treated by surgeons immediately.

This Exotic Particle Had an Out-of-Body Experience; These Scientists Took a Picture of It
An unexpected finding by scientists at Berkeley Lab and UC Berkeley could advance quantum computers and high-temperature superconductors Scientists have taken the clearest picture yet of electronic particles that make up a mysterious magnetic state called a quantum spin liquid (QSL). The achievement could facilitate the development of superfast quantum computers and energy-efficient superconductors.

Modeling uncovers an 'atomic waltz' for atom manipulation
Modeling uncovers an ’atomic waltz’ for atom manipulation
Researchers at the University of Vienna's Faculty of Physics in collaboration with colleagues from the Oak Ridge National Laboratory in the USA have uncovered a non-destructive mechanism to manipulate donor impurities within silicon using focused electron irradiation. In this novel indirect exchange process not one but two neighbouring silicon atoms are involved in a coordinated atomic "waltz", which may open a path for the fabrication of solid-state qubits.

Neanderthals indeed painted Andalusia's Cueva de Ardales
Neanderthals indeed painted Andalusia’s Cueva de Ardales
The origin and date of appearance of prehistoric cave art are the subjects of ongoing debate. Spain's Cueva de Ardales is one point of discussion. There a flowstone formation is stained red in places. This colouring is apparently almost 65,000 years old 1 but until now, a part of the scientific community attributed it to a natural coating of iron oxide deposited by flowing water.

Science with teeth: Researchers use X-rays to find rare mineral in mollusk tooth
Rare mineral used to create a new ink for 3D printing of prosthetics and devices for space travel A rare mineral inside the teeth of a large mollusk found along rocky coastlines led to a bio-inspired ink for 3D printing and may also one day be used in the emerging field of soft robotics, according to researchers who made the discovery while working at Argonne National Laboratory, a U.S. Department of Energy national lab which is affiliated with the University of Chicago.

Simulated microgravity system created to experiment with materials
Simulated microgravity system created to experiment with materials
Crystallization studies conducted in space laboratories, which are costly and unaffordable for most research laboratories, showed the valuable effects of microgravity during the crystal growth process and the morphogenesis of materials. Now, a research study led by a scientific team of the University of Barcelona, has created an easy and efficient method to achieve experimentation conditions of microgravity on Earth that simulate those in space.

Spin-sonics: Acoustic wave gets the electrons spinning: Team of researchers first to demonstrate spin of a nano-sonic wave
Spin-sonics: Acoustic wave gets the electrons spinning: Team of researchers first to demonstrate spin of a nano-sonic wave
A team of German and American researchers from Augsburg, Münster, Edmonton, West Lafayette and Munich have detected the rolling movement of a nano-acoustic wave predicted by the famous physicist and Nobel prize-winner Lord Rayleigh in 1885. In a study published in the journal "Science Advances", the researchers use a nanowire inside which electrons are forced onto circular paths by the spin of the acoustic wave.

First synthetic tissue model developed in which blood vessels can grow
Researchers investigate which material properties support vessel formation / Study published in the journal "Nature Communications" Using lab-created tissue to heal or replace damaged organs is one of the great visions for the future of medicine. Synthetic materials could be suitable as scaffolding for tissue because, unlike natural tissues, they remain stable in the organism long enough for the body to form new natural structures.

Plasma tech could replace one of world's rarest materials
Plasma tech could replace one of world’s rarest materials
New plasma coating technology could see the phase-out of rare earth metal indium that is used in smartphone glass and dimmable windows, which is predicted to run out in 10 years. A team led by a researcher from the University of Sydney has developed a low-cost, sustainable, and readily available technology that can dim the screens of electronic devices, anti-reflection automobile mirrors, and smart architectural windows at a fraction of the cost of current technology.  It would replace one of the world's scarcest - yet highly ubiquitous in use - modern materials: indium.
