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
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
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
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
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
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
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
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
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.

Watching light beams go out
A team from the Friedrich Schiller University Jena has set up a new streak camera on ID16B, which can measure very fast kinetic phenomena present in light emission after receiving an X-ray pulse. The camera is now available to the user community to study complex carrier dynamics with spatio-temporal resolutions.

How ’2D’ materials expand
A new technique that accurately measures how atom-thin materials expand when heated could help engineers develop faster, more powerful electronic devices. Two-dimensional materials, which consist of just a single layer of atoms, can be packed together more densely than conventional materials, so they could be used to make transistors, solar cells, LEDs, and other devices that run faster and perform better.

Ceramic coatings do not fatigue
What determines the durability of high-performance coatings for turbines or highly stressed tools? Surprising results from TU Wien show: It is not material fatigue. Extremely thin ceramic coatings can completely change the properties of technical components. Coatings are used, for example, to increase the resistance of metals to heat or corrosion.

With new heat treatment, 3D-printed metals can withstand extreme conditions
A technique that transforms the metals' microscopic structure may enable energy-efficient 3D printing of blades for gas turbines or jet engines. A new MIT-developed heat treatment transforms the microscopic structure of 3D-printed metals, making the materials stronger and more resilient in extreme thermal environments.
