Chemical processes that are more efficient and less expensive may be coming to industries ranging from battery manufacturing to detergent production thanks to work that advances the use of metal oxides as catalysts.
Researchers have created a motion-powered, fireproof sensor that can track the movements of firefighters, steelworkers, miners and others who work in high-risk environments where they cannot always be seen.
Researchers report a unipolar n-type transistor with a world-leading electron mobility performance of up to 7.16 cm2 V-1 s-1. This achievement heralds an exciting future for organic electronics, including the development of innovative flexible displays and wearable technologies.
Researchers have discovered that a technique known as nanopore sensing can be used to detect subtle changes in clusters, or extremely small chunks of matter that are bigger than a molecule but smaller than a solid.
A team of researchers is working to upend energy-intensive, fossil fuel-dependent chemical manufacturing processes and replace them with sustainable, solar-driven reactions that rely on renewable feedstocks. The team recently designed a novel reactor that uses solar energy and plant waste to sustainably produce adiponitrile, an precursor material used in Nylon production.
Inspired by the refined electrochemistry of electric car batteries, scientists have developed a battery-like system that allows them to make potential advancements for the manufacturing of medicines. Their new method avoids safety risks associated with a type of chemical reaction known as dissolving metal reduction. Their method would offer significant advantages over current methods of chemical manufacturing, but until now, has largely been sidelined due to safety considerations.
Northwestern University researchers have developed a blueprint for understanding and predicting the properties and behavior of complex nanoparticles and optimizing their use for a broad range of scientific applications. These include catalysis, optoelectronics, transistors, bio-imaging, and energy storage and conversion.
Nanostructures based on carbon are promising materials for nanoelectronics. However, to be suitable, they would often need to be formed on non-metallic surfaces, which has been a challenge -- up to now. Researchers have found a method of forming nanographenes on metal oxide surfaces.
Once thought rare, strangely behaving substances called 'topological materials' are in fact quite common, a finding that bodes well for their potential use in future electronics. An international team of researchers has assembled an online catalog, based on the periodic table, to make it easy to design new versions of these unusual materials.
The researchers found that transient formation of hydrogen bonding between a substrate and the catalyst induced such high segregation in the reaction. By using inexpensive and readily available feedstock hydrocarbons, the researchers produced a group of chiral lactams in different shapes. Their diverse structures allow lactams to correspond to different pharmaceutical drugs.
The remarkable properties of a recently-discovered squid protein could revolutionize materials in a way that would be unattainable with conventional plastic. Originating in the ringed teeth of a squid's predatory arms, this protein can be processed into fibers and films with applications ranging from health-monitoring 'smart' clothes to self-healing recyclable fabrics that reduce microplastic pollution. Materials made from this protein are eco-friendly and biodegradable, with sustainable large-scale production achieved using laboratory culture methods.
In order to explain the known anomalies in water, some researchers assume that water consists of a mixture of two phases even under ambient conditions. However, new X-ray spectroscopic analyses show that this is not the case. At room temperature and normal pressure, the water molecules form a fluctuating network with an average of 1.74 ± 2.1 percent donor and acceptor hydrogen bridge bonds per molecule each, allowing tetrahedral coordination between close neighbors.
