Engineers grow 'perfect' atom-thin materials on industrial silicon wafers
Engineers grow ’perfect’ atom-thin materials on industrial silicon wafers
Their technique could allow chip manufacturers to produce next-generation transistors based on materials other than silicon. Close True to Moore's Law, the number of transistors on a microchip has doubled every year since the 1960s. But this trajectory is predicted to soon plateau because silicon - the backbone of modern transistors - loses its electrical properties once devices made from this material dip below a certain size.

Improving perovskite solar cell resistance to degradation
Improving perovskite solar cell resistance to degradation
Despite their huge potential, the way perovskite solar cells respond to external stimuli - such as heat or moisture - has a considerable impact on their stability. Researchers at EPFL have identified the cause of degradation and developed a technique to improve stability, bringing us closer to widespread adoption of these cost-effective and efficient solar cells.

Customized Electrolyte Additives Boost Battery Cell Performance
Phosphazene-Based Electrolyte Additives Stabilize Silicon-Based Lithium-Ion Batteries Silicon (Si) is considered a promising anode material in next-generation lithium-ion batteries (LIB). Its practical application has so far been hindered by challenges such as capacity losses during battery operation.

Simulations Transform Coal-Like Material to Amorphous Graphite and Nanotubes
In a warming world, coal can often seem the "bad guy," but coal has uses aside from burning it. A team at Ohio University used the Pittsburgh Supercomputing Center 's Bridges-2 system to carry out a series of simulations showing how coal might eventually be converted to valuable - and carbon-neutral - materials like graphite and carbon nanotubes.

Electronic Bridge Allows Rapid Energy Sharing between Semiconductors
As semiconductor devices become ever smaller, researchers are exploring two-dimensional (2D) materials for potential applications in transistors and optoelectronics. Controlling the flow of electricity and heat through these materials is key to their functionality, but first we need to understand the details of those behaviors at atomic scales.

Cool New Method of Refrigeration
Adding salt to a road before a winter storm changes when ice will form. Researchers at the Department of Energy's Lawrence Berkeley National Laboratory ÜBerkeley Lab) have applied this basic concept to develop a new method of heating and cooling. The technique, which they have named "ionocaloric cooling," is described in a paper published Dec.

Efficiency of solar cells directly linked to R&D efforts
Efficiency of solar cells directly linked to R&D efforts
Professor Phillip Dale of the University of Luxembourg and Professor Mike Scarpulla of the University of Utah have discovered that researchers improve the efficiency of solar cells, the constituents of photovoltaic panels, at the same rate independently of the technology over the last decades.

Brittle concrete walls: researchers find the cause
Brittle concrete walls: researchers find the cause
After extensive analyses, researchers found the cause of the concrete scandal in County Donegal, Ireland, where structural damage has been causing red faces and protests for years: Concrete walls of thousands of houses are riddled with cracks, necessitating expensive repairs or even demolition. For the longest time, an excessively high mica content in the concrete was thought to be the reason.

Lucky find! How science behind epidemics helped Sussex physicists to develop state-of-the-art conductive paint
Lucky find! How science behind epidemics helped Sussex physicists to develop state-of-the-art conductive paint
In new research published in Nature Communications , University of Sussex scientists demonstrate how a highly conductive paint coating that they have developed mimics the network spread of a virus through a process called 'explosive percolation' - a mathematical process which can also be applied to population growth, financial systems and computer networks, but which has not been seen before in materials systems.

Risk of population disruption as a result of decarbonisation
Risk of population disruption as a result of decarbonisation
Researchers including Göttingen University analyse resources, demographics and disruption in energy transition Research led by University of Queensland (UQ) and including the University of Göttingen analysed the effects of decarbonisation strategies by linking global resource inventories with demographic systems to generate a matrix showing the risks and benefits.

New process boosts efficiency of bifacial CIGS thin film solar cell
New process boosts efficiency of bifacial CIGS thin film solar cell
Bifacial thin film solar cells based on copper indium gallium diselenide or CIGS can collect solar energy from both their front and their rear side - and thus potentially yield more solar electricity than their conventional counterparts. So far, however, their fabrication has led to only modest energy conversion efficiencies.

Watch this robot do 'The Worm' when temperature changes
Watch this robot do ’The Worm’ when temperature changes
Creators at Johns Hopkins envision 'gelbots' crawling through human bodies to deliver medicine A new gelatinous robot that crawls, powered by nothing more than temperature change and clever design, brings "a kind of intelligence" to the field of soft robotics. The inchworm-inspired work is detailed today in Science Robotics .

Gold-based passive heating for eyewear
Gold-based passive heating for eyewear
Researchers from ETH Zurich have developed a new transparent gold nanocoating that harnesses sunlight to heat the lenses of glasses, thereby preventing them from fogging in humid conditions. This coating could potentially also be applied to car windshields. Researchers at ETH Zurich have developed an ultrathin, gold-based transparent coating that is able to convert sunlight into heat.

Watching viruses fail
Watching viruses fail
Using a new analytical method, researchers have tracked viruses as they pass through face masks and compared their failure on the filter layers of different types of masks. The new method should now accelerate the development of surfaces that can kill viruses, the team writes in the journal Scientific Reports.

Detecting defects in semiconductors at the atomic level
Detecting defects in semiconductors at the atomic level
Modern solar cells work with thin layers of semiconductors that convert sunlight into electrical energy. The key to increasing their efficiency even further lies in the composition and structure of the material. Due to the way the material is manufactured, it can have defects that have a disruptive effect.

Evidence at last for long-awaited new liquid crystal phase
Evidence at last for long-awaited new liquid crystal phase
Fifty years after scientists predicted a new liquid crystalline phase, it has been observed by Utrecht researchers. The observations were made in model systems of colloidal rods, rod-like particles that are larger than molecules and therefore easier to study. The researchers provide guidance on a way to realize the material with rod-shaped molecules as well.

A sensitive drill
Hearing-impaired people whose auditory nerve is still intact can often be helped with a cochlear implant. But inserting the implant into the inner ear is not without risks, as facial nerves can be damaged in the process. researchers have developed a novel smart drill that minimizes the risk by automatically shutting off when it comes near nerves.
