Published Bioinspired protein creates stretchable 2D layered materials


Nature creates layered materials like bone and mother-of-pearl that become less sensitive to defects as they grow. Now researchers have created, using biomimetic proteins patterned on squid ring teeth, composite layered 2D materials that are resistant to breaking and extremely stretchable.
Published Buckyballs on gold are less exotic than graphene


C60 molecules on a gold substrate appear more complex than their graphene counterparts, but have much more ordinary electronic properties. This is now shown by measurements with ARPES at BESSY II and detailed calculations.
Published Just 10 financial actors hold the key to climate change


A new report has identified the 10 financial actors with the most influence on the fossil fuel economy and outlines the decisive role they can play in helping de-carbonize our future.
Published All-in-one solar-powered tower makes carbon-neutral jet fuel


Researchers have designed a fuel production system that uses water, carbon dioxide (CO2), and sunlight to produce aviation fuel. They have implemented the system in the field, and the design could help the aviation industry become carbon neutral.
Published Ultrasonic detectors reveal the detrimental effect of wind turbines at forest sites on bats


As more and more wind turbines (WTs) are installed in the course of the energy transition and distance regulations to human settlements are tightened, suitable locations are becoming increasingly difficult to find. As a result, wind turbines are increasingly being erected in forests -- to the detriment of forest specialists among bats.
Published New research furthers understanding of the electronic structure of graphite


Graphite is an incredibly important, versatile mineral, with uses spanning industries. Graphite is an essential component of many batteries, including lithium-ion batteries, and demand is only increasing as new technology is developed. Surprisingly, no spectroscopic studies have so far accurately measured the electronic states of the surface and the edge of graphite from a microscopic point of view. Indeed, the improvement in battery performance depends largely on the control of the characteristics of the graphite at the tip.
Published Researcher uses graphene for same-time, same-position biomolecule isolation and sensing


New research has overcome a major challenge to isolating and detecting molecules at the same time and at the same location in a microdevice. The work demonstrates an important advance in using graphene for electrokinetic biosample processing and analysis and could allow lab-on-a-chip devices to become smaller and achieve results faster.
Published Fuel cells: Novel multi-proton carrier complex as efficient proton conductor at high temps


Fuel cells often fall short when it comes to operating at temperatures beyond 100 degrees Celsius owing to their dependence on water as a proton conduction medium. To overcome this issue, a team of researchers designed a new hydrogen-bonded starburst-shaped metal complex consisting of ruthenium (III) ion and six imidazole-imidazolate groups. The resulting single molecular crystal shows excellent proton conductivity even at temperatures as high as 180°C and as low as --70 °C.
Published Research team accelerates imaging techniques for capturing small molecules' structures


A new research effort is accelerating imaging techniques to visualize structures of small molecules clearly -- a process once thought impossible. Their discovery unleashes endless potential in improving everyday life applications -- from plastics to pharmaceuticals.
Published Flashing creates hard-to-get 2D boron nitride



Chemists use their flash Joule heating process to synthesize 2D flakes of boron nitride and boron carbon nitride, highly valued for lending thermal and chemical stability to compounds.
Published Thin mica shows semiconducting behavior, say scientists in new study



Muscovite mica (MuM) is a highly stable mineral that is commonly used as an insulator. However, the electrical properties of single-layer and few-layered MuM are not well understood. Now, a group of researchers reports and explains unusually high conductivity in MuM flakes that are only a few molecule layers thick. Their findings could open doors to the development of two-dimensional electronic devices that are robust against harsh environments.
Published Solar-powered chemistry uses carbon dioxide and water to make feedstock for fuels, chemicals


Solar-powered synthesis gas could recycle carbon dioxide into fuels and useful chemicals, an international team of researchers has shown.
Published Caught in the act: Key chemical intermediates in pollutant-to-fuel reaction identified


Researchers identified chemical intermediates in the hydrogenation of copper-adsorbed formate. Depending on the temperature, some of the hydrogenation product decomposed into formaldehyde. The activation energy was also quantified, based on experimental and computational work. These results will be useful for optimizing production of methanol fuel from carbon dioxide.
Published Offshore wind farms expected to reduce clam fishery revenue, study finds


An important East Coast shellfish industry is projected to suffer revenue losses as offshore wind energy develops along the U.S. Northeast and Mid-Atlantic coasts, according to two recent studies.
Published Modern wind turbines can more than compensate for decline in global wind resource


Wind energy contributes significantly to the energy sector's sustainable, low-CO2 transformation. However, the efficiency of wind turbines depends on available wind resources and the technical characteristics of the turbines.
Published Inspired by palm trees, scientists develop hurricane-resilient wind turbines


New results from real-world tests of a downwind turbine could inform and improve the wind energy industry in a world with intensifying hurricanes and a greater demand for renewable energy.
Published Death of bats at wind turbines interrupts natural food chains


The numerous casualties of bats at wind turbines (WT) have a negative impact on the populations of affected species and potentially far-reaching consequences for the biodiversity in rural areas. Until now, it could only be assumed that the death of bats had further consequences. Now, a team of scientists show that natural food chains are interrupted, which can have far-reaching negative consequences for agriculture and forestry. The study demonstrates the extent to which the functional importance of bats for habitats has been underestimated so far.
Published Earth-abundant solar pixels found to produce hydrogen for weeks


Devices made of readily available oxide and carbon-based materials can produce clean hydrogen from water over weeks -- according to new research. The findings could help overcome one of the key issues in solar fuel production, where current earth-abundant light-absorbing materials are limited through either their performance or stability.
Published Ancient ocean floors could help in the search for critical minerals


Studying ancient ocean floors could help us discover minerals needed to produce electric cars and solar panels.
Published Wind turbines operating without curtailment claim many victims among protected bat species in Germany


Protected and rare bats regularly die at wind turbines (WT). This is why the operation of new wind turbines is temporarily curtailed during periods of high bat activity. Old wind turbines run without curtailment, however. A scientific team has now produced an exemplary estimate of bat fatality rates at such old turbines by systematically recording bat carcasses in the vicinity of the turbines. During two months, 70 bats died on average per wind turbine. Even if these figures cannot be extrapolated one-to-one to all 20,000 old turbines in Germany, there is a considerable need for action. The operation of old turbines should be adjusted to the current regulations for new turbines, the authors argue.
