Researchers developed lithium-ion batteries that perform well at freezing cold and scorching hot temperatures, while packing a lot of energy. This could help electric cars travel farther on a single charge in the cold and reduce the need for cooling systems for the cars' batteries in hot climates.

Schiff base-metal complexes exhibit promising antibacterial and antioxidant properties. However, conventional methods for their preparation can be time-consuming. To reduce the reaction time and improve the quality and quantity of the products, researchers designed a new synthesis technique that uses microwave irradiation and methanol for the preparation of amino acid Schiff base copper complexes in just 10 minutes. The resulting products exhibit desirable properties, such as mild antioxidant activity and antibacterial activity against Escherichia coli.

Researchers improve a widely used simulation method for high-performance computing clusters.

Biofuel scientists used an oddball molecule made by bacteria to develop a new class of sustainable biofuels powerful enough to launch rockets. The candidate molecules have greater projected energy density than any petroleum product, including the leading aviation and rocket fuels, JetA and RP-1.

Scientists have developed a fast and economical method of converting methane, or natural gas, into liquid methanol at ambient temperature and pressure. The method takes place under continuous flow over a photo-catalytic material using visible light to drive the conversion.To help observe how the process works and how selective it is, the researchers used neutron scattering.

The eruption of the Hunga Tonga-Hunga Ha'apai submarine volcano in January 2022 was one of the most explosive volcanic events of the modern era, a new study has confirmed.

Environmental sensors are a step closer to simultaneously sniffing out multiple gases that could indicate disease or pollution. Researchers combined laser writing and responsive sensor technologies to fabricate the first highly customizable microscale gas sensing devices.

Only a fraction of the material that could be turned into new plastic is currently recycled. Researchers have now demonstrated how the carbon atoms in mixed waste can replace all fossil raw materials in the production of new plastic. The recycling method is inspired by the natural carbon cycle and could eliminate the climate impact of plastic materials, or even clean the air of carbon dioxide.

Researchers have found that organic vapor can dissolve molecular salts in a phenomenon known as organic deliquescence. Similar to how water vapor can induce deliquescence of compounds like calcium chloride, this phenomenon will be useful for developing methods for capturing harmful volatile organic compounds (VOCs). There is an urgent need to remove them from indoor environments, particularly industrial facilities, where concentrations are highest.

The current system of chemical risk assessment is inadequate and underestimates levels of flame retardants and other pollutants needed to cause harmful health effects, according to a recent analysis.
