A cheaper way to scale up atomic layer deposition
Chemical engineers at EPFL have developed a new method for atomic layer deposition, a technique commonly used in high-quality microelectronics. The new method can be used in materials with larger surfaces much more cheaply than current approaches, while preserving quality and efficiency. Atomic layer deposition (ALD) involves stacking layers of atoms on top of each other like pancakes.

A fast and precise look into fibre-reinforced composites
A fast and precise look into fibre-reinforced composites
Researchers at the Paul Scherrer Institute PSI have improved a method for small angle X-ray scattering (SAXS) to such an extent that it can now be used in the development or quality control of novel fibre-reinforced composites. This means that in the future, such materials can be investigated not only with X-rays from especially powerful sources such as the Swiss Light Source SLS, but also with those from conventional X-ray tubes.

Go With the Flow: Scientists Design Better Batteries for a Renewable Energy Grid
Go With the Flow: Scientists Design Better Batteries for a Renewable Energy Grid
New blueprint for affordable, sustainable 'flow batteries' developed at Berkeley Lab could accelerate an electrical grid powered by the sun and wind How do you store renewable energy so it's there when you need it, even when the sun isn't shining or the wind isn't blowing? Giant batteries designed for the electrical grid - called flow batteries, which store electricity in tanks of liquid electrolyte - could be the answer, but so far utilities have yet to find a cost-effective battery that can reliably power thousands of homes throughout a lifecycle of 10 to 20 years.

UK needs to act to prevent electric vehicle battery waste mountain - new study
Recycling technologies for end-of-life lithium ion batteries (LIBs) are not keeping pace with the rapid rise of electric vehicles, storing up a potentially huge waste management problem for the future, according to a new study. A review of lithium ion battery recycling led by the University of Birmingham suggests that, while electric vehicles (EVs) offer a solution for cutting pollution, governments and industry need to act now to develop a robust recycling infrastructure to meet future recycling need.

4D-STEM Microscopes Take Candid Snapshots of Atomic ’Neighborhoods’
Scientists use powerful 4D-STEM electron microscopy technique to map out the best atomic 'hangouts' in high-performance materials W e can directly see the hidden world of atoms thanks to electron microscopes, first developed in the 1930s. Today, electron microscopes, which use beams of electrons to illuminate and magnify a sample, have become even more sophisticated, allowing scientists to take real-world snapshots of materials with a resolution of less than half the diameter of a hydrogen atom.

Light-based 'tractor beam' assembles materials at the nanoscale
Light-based ’tractor beam’ assembles materials at the nanoscale
Modern construction is a precision endeavor. Builders must use components manufactured to meet specific standards - such as beams of a desired composition or rivets of a specific size. The building industry relies on manufacturers to create these components reliably and reproducibly in order to construct secure bridges and sound skyscrapers.

New technique lets researchers map strain in next-gen solar cells
New technique lets researchers map strain in next-gen solar cells
People can be good at hiding strain, and we're not alone. Solar cells have the same talent. For a solar cell, physical strain within its microscopic crystalline structure can interrupt its core function - converting sunlight into electricity - by essentially "losing” energy as heat. For an emerging type of solar cell, known as lead halide perovskites, reducing and taming this loss is key to improving efficiency and putting the perovskites on par with today's silicon solar cells.

Monitoring the corrosion of bioresorbable magnesium
Monitoring the corrosion of bioresorbable magnesium
ETH researchers have recently been able to monitor the corrosion of bioresorbable magnesium alloys at the nanoscale over a time scale of a few seconds to many hours. This is an important step towards accurately predicting how fast implants are resorbed by the body to enable the development of tailored materials for temporary implant applications.

Bioprinting: Living cells in a 3D printer
With a new process developed at TU Wien (Vienna), living cells can be integrated into fine structures created in a 3D printer - extremely fast and with very high resolution. Tissue growth and the behavior of cells can be controlled and investigated particularly well by embedding the cells in a delicate 3D framework.

Physicists shed new light on how liquids behave with other materials
Using a range of theoretical and simulation approaches, physicists from the University of Bristol have shown that liquids in contact with substrates can exhibit a finite number of classes of behaviour and identify the important new ones. Their findings, published in the Proceedings of the National Academy of Sciences (PNAS) , challenge the accepted wisdom on wetting and drying phase behaviour.

Solving the Mystery of Quantum Light in Thin Layers
Solving the Mystery of Quantum Light in Thin Layers
A very special kind of light is emitted by tungsten diselenide layers. The reason for this has been unclear. Now an explanation has been found at TU Wien (Vienna). It is an exotic phenomenon that nobody was able to explain for years: when energy is supplied to a thin layer of the material tungsten diselenide, it begins to glow in a highly unusual fashion.

Cells’ mitochondria work much like Tesla battery packs
For years, scientists assumed that mitochondria — the energy-generating centers of living cells — worked much like household batteries, generating energy from a chemical reaction inside a single chamber or cell. Now, UCLA researchers have shown that mitochondria are instead made up of many individual bioelectric units that generate energy in an array, similar to a Tesla electric car battery that packs thousands of battery cells to manage energy safely and provide fast access to very high current.

Archives Digitize Decades of Mellon Institute Records
Carnegie Mellon's University Libraries have organized and preserved 347 boxes of records from the Mellon Institute of Industrial Research, one of the nation's premier independent research centers, making the records more widely discoverable and available to researchers. "No one has written a comprehensive history on the Mellon Institute, how it factored into the larger industrial research ecosystem or its contributions to science," said Project Archivist Emily Davis, who led the digitization effort.

Romantic Replicas
Romantic Replicas
To play a piece of music as it was conceived by the composer is a trend. But where can the rare historical instruments be found? The solution would be exact copies of the coveted originals. A team of Empa researchers is analysing such replicas with the aim of reproducing historical trombones with their typical sound.
