Data-frugal Deep Learning Optimizes Microstructure Imaging
Deep learning is often recognized as the magic behind self-driving cars and facial recognition, but what about its ability to safeguard the quality of the materials that make up these advanced devices? Carnegie Mellon University Professor of Materials Science and Engineering Elizabeth Holm and materials science and engineering doctoral candidate Bo Lei have adopted computer vision methods for microstructural images that not only require a fraction of the data deep learning typically relies on, but can save materials researchers an abundance of time and money.

Templating approach stabilises 'ideal' material for alternative solar cells
Templating approach stabilises ’ideal’ material for alternative solar cells
Researchers have developed a method to stabilise a promising material known as perovskite for cheap solar cells, without compromising its near-perfect performance. The researchers, from the University of Cambridge, used an organic molecule as a 'template' to guide perovskite films into the desired phase as they form.

’Pop-up’ Electronic Sensors Could Detect When Individual Heart Cells Misbehave
Engineers at the University of California San Diego have developed a powerful new tool that monitors the electrical activity inside heart cells, using tiny "pop-up" sensors that poke into cells without damaging them. The device directly measures the movement and speed of electrical signals traveling within a single heart cell—a first—as well as between multiple heart cells.

Spray-on coating could make solar panels snow-resistant
In an advance that could dramatically improve the productivity of solar panels in cold climates, a University of Michigan-led team has demonstrated an inexpensive, clear coating that reduced snow and ice accumulation on solar panels, enabling them to generate up to 85% more energy in early testing. The coating is made chiefly of PVC or PDMS plastic and silicon or vegetable-based oils.

How a floating fern withstands the rain
How a floating fern withstands the rain
The tropical floating fern Salvinia molesta has developed sophisticated structures to allow water to roll off its leaves quickly - even during heavy rainfall. This relieves the pressure on the leaves floating on the water surface, but even more importantly, it keeps the stomata open for air exchange.

Shellac for printed circuits
Shellac for printed circuits
Intelligent packaging with sensors that monitor goods, such as vegetables, on long transport routes is a trend for the future. Yet printed and disposable electronics also cause problems: Metals in printing inks are expensive - and disposing of them in an environmentally sound manner is costly and exacerbates the problem of electronic waste.

'Wonder material' phosphorene nanoribbons live up to hype in first demonstration
’Wonder material’ phosphorene nanoribbons live up to hype in first demonstration
Phosphorene nanoribbons have been incorporated into new types of solar cells, dramatically improving the cells' efficiency, in a new study led by UCL and Imperial College London researchers. Phosphorene nanoribbons (PNRs) are ribbon-like strands of the 2D material phosphorous, which, similar to graphene, are made of single-atom-thick layers of atoms.

Nuclear ’shadow corrosion’ reproduced in the lab, paving way to longer fuel life
Now that it's understood, researchers are on their way to preventing this type of degradation in nuclear power plants Solutions to a 55-year-old problem in boiling water reactors-which represent a third of nuclear power reactors in the United States-are on the way now that the problem has been emulated with ion beams.

New approach to predicting battery failure could help maintain electricity for millions around the world
The new method of predicting battery failure is 15 - 20% more accurate than current approaches. Millions of people around the world lack access to electricity. Decentralised solar-battery systems are key for addressing this whilst avoiding carbon emissions and air pollution, but are hindered by relatively high costs and rural locations that inhibit timely preventative maintenance.

Research Team Proposes New Approach for Next-Generation Memories with RRAM Energy-Storage Breakthrough
In-memory energy is a supplemental feature to in-memory computing, which is a key focus in CEA-Leti's roadmap. It can reduce energy use dramatically because RRAM-based batteries are highly scalable and dynamically allocable, and they can be placed next to memory blocks, which are near the processor. Locating the energy supply close to the processor is especially helpful when the processor requires peak power, which typically comes from an external source.

'Super jelly' can survive being run over by a car | University of Cambridge
’Super jelly’ can survive being run over by a car | University of Cambridge
Researchers have developed a jelly-like material that can withstand the equivalent of an elephant standing on it, and completely recover to its original shape, even though it's 80% water. At 80% water content, you'd think it would burst apart like a water balloon, but it doesn't: it stays intact and withstands huge compressive forces Oren Scherman The soft-yet-strong material, developed by a team at the , looks and feels like a squishy jelly, but acts like an ultra-hard, shatterproof glass when compressed, despite its high water content.

Graphene-like 2D material leverages quantum effects to achieve ultra-low friction
Graphene-like 2D material leverages quantum effects to achieve ultra-low friction
Researchers from the University of Toronto's Faculty of Applied Science & Engineering and Rice University have reported the first measurements of the ultra-low-friction behaviour of a material known as magnetene. The results point the way toward strategies for designing similar low-friction materials for use in a variety of fields, including tiny, implantable devices.  Magnetene is a 2D material, meaning it's composed of a single layer of atoms.

Refuting A 70-year Approach To Predicting Material Microstructure
Carnegie Mellon University A 70-year-old model used to predict the microstructure of materials doesn't work, according to Carnegie Mellon researchers in Science. A microscopy technique developed by Carnegie Mellon and Argonne National Laboratory yields evidence that contradicts the conventional model and points the way toward the use of new types of characterizations to predict properties - and therefore the safety and long-term durability - of new materials.

An ironclad future
An ironclad future
Solar energy plays an important role in the fight against climate change as a substitute for fossil fuels. Dye-sensitized solar cells promise to be a low-cost supplement to the photovoltaic systems we know today. Their key feature is the dye sensitizers attached to their surface. Researchers at the University of Basel continue to improve the performance with sensitizers using iron - a commonly available and environmentally friendly metal.
