To combat the hazards of ice, a mechanical engineer has developed a sprayable ice-shedding material that is 100 times stronger than any others. It's been tested by Boeing under erosive rain conditions at 385 miles per hour and outperformed current state-of-the-art aerospace coating technologies.

Scientists have gotten bacteria to spontaneously take up fluorescent carbon nanotubes for the first time. The breakthrough unlocks new biotechnology applications for prokaryotes, such as near-infrared bacteria tracking and 'living photovoltaics' -- devices that generate energy using light-harvesting bacteria.

A team of researchers has discovered a way to convert 100% of carbon dioxide captured from industrial exhaust into ethylene, a key building block for plastic products.

Researchers report that strain caused by just a 2% reduction in the distance between atoms when deposited on a surface leads to a whopping 99.999% decrease in the speed at which the materials conduct hydrogen ions, greatly reducing the performance of solid oxide fuel cells. Developing methods to reduce this strain will help bring high-performance fuel cells for clean energy production to a wider number of households in the future.

Scientists describe the formation of a superdense monolayer of hydrogen on highly ordered mesoporous silica near the boiling temperature. Theoretical studies and simulations confirm the experimental observations of the unusually high hydrogen density in the adsorbed layer and may also open new possibilities for enhancing the volumetric capacity of cryogenic hydrogen storage systems.

Solar cells manufactured from materials known as 'perovskites' are catching up with the efficiency of traditional silicon-based solar cells. At the same time, they have advantages of low cost and short energy payback time. However, such solar cells have problems with stability -- something that researchers have now managed to solve. The results are a major step forwards in the quest for next-generation solar cells.

Accelerating demand for renewable energy and electric vehicles is sparking a high demand for the batteries that store generated energy and power engines. But the batteries behind these sustainability solutions aren't always sustainable themselves. Scientists have now create a zinc battery with a biodegradable electrolyte from an unexpected source -- crab shells.

Wind power is an increasingly popular form of renewable energy. But when it's time to replace the huge turbine blades that convert wind into electricity, disposal is a problem. Today, scientists report a new composite resin for making these behemoths that could later be recycled into new turbine blades or many other products, including countertops, car taillights, diapers and even gummy bears.

Wind energy continues to see strong growth, solid performance, and attractive prices in the U.S., according to a recent report.

Orchestral ensembles have faced many challenges when starting to perform again during the COVID pandemic, and contamination is a chief concern: specifically, whether wind instruments are vectors of contamination through aerosol dispersion. Researchers worked with musicians to deepen our understanding of how much aerosol is produced and dispersed by wind instruments. They used visualization to characterize the flow, tracked fog particles in the air, and measured aerosol concentration from wind instruments with a particle counter. Then they combined these to develop an equation to describe aerosol dispersion.

Engineers have developed a method to increase wind farms' energy output. Whereas individual turbines are typically controlled separately, the new approach models the wind flow of the entire collection of turbines and optimizes the control of individual units.

New algorithm forces turbines in wind farms to be team players, boosting energy output overall.

Across the United States, local wind and solar jobs can fully replace the coal-plant jobs that will be lost as the nation's power-generation system moves away from fossil fuels in the coming decades, according to a new study.

While scientists have hoped that rechargeable zinc-manganese dioxide batteries could be developed into a viable alternative for grid storage applications, engineers have now identified the atomistic mechanism of charge and discharge in such batteries.

Engineers have designed and successfully tested a more efficient wind sensor for use on drones, balloons and other autonomous aircraft.

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.

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.

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.
