Regenerative energy harvesting often generates more electricity than is directly needed. Although intensive research on the catalysts required for this has been going on for 20 years, progress is only being made in small steps.

Researchers discovered a way to bind and stack nanoscale clusters of copper molecules that can self-assemble and mimic these complex biosystem structures at different length scales. The clusters provide a platform for developing new catalytic properties that extend beyond what traditional materials can offer.

Researchers used an ultrathin graphene 'sandwich' to create a tiny magnetic field sensor that can operate over a greater temperature range than previous sensors, while also detecting miniscule changes in magnetic fields that might otherwise get lost within a larger magnetic background.

Scientists propose a new method to confine light in an atomically thin graphene layer by leveraging topological phenomena that occur at the interface of specially designed nanomaterials.

New anti-bacterial surfaces are being developed, featuring different nanopatterns that mimic the deadly action of insect wings, but scientists are only beginning to unravel the mysteries of how they work.

Scientists summarize recent developments in the field of nanofiltration and provide guidance for potential future approaches to improve the selectivity of nanofiltration membranes.

Killer cosmic rays from nearby supernovae could be the culprit behind at least one mass extinction event, researchers said, and finding certain radioactive isotopes in Earth's rock record could confirm this scenario.

Understanding the alignment phenomena of a nematic liquid crystals on nanostructured surfaces remains an important area of research, as the alignment process determines the LC's molecular orientation and conformation - which influence the LC's optical and electro-optical characteristics in modern LCDs. Researchers report that an inorganic nanostructured surface - vertically aligned carbon nanotube arrays - can be employed as the alignment agent to design an electro-optic homeotropic LC device.

For the first time, scientists were able to observe how electronic charge excitation changes electron spin in metal oxides in an ultrafast and inphase manner.

An international team of researchers have discovered a dense, cold gas that's been shot out from the centre of the Milky Way 'like bullets'.

Researchers have developed a prototype device that non-invasively detected COVID-19 in the exhaled breath of infected patients.

Scientists have developed a light-activated coating for filtration membranes - the kind used in water treatment facilities, at semiconductor manufacturing sites and within the food and beverage industry - to make them self-cleaning, eliminating the need to shut systems down in order to repair them.

One way to determine whether there is life on another planet is to look for biosignatures in the light that is scattered off its atmosphere. Scientists have developed an original model that interprets the results of that analysis.

Scientists have discovered a hitherto-unknown physical phenomenon in an artificial material made up of very thin layers of nickelates. This could be exploited to accurately control some of the material?s electronic properties, such as the sudden transition from a conductive to an insulating state.

Researchers use diamondization of mechanically exfoliated few-layer graphene via compression, to synthesize the long-sought-after diamane film.

Researchers have exploited the opto-thermoelectric effect to develop a new type of all-optical microswimmers with active navigation functionality. These microswimmers consist of individual Janus particles - polystyrene beads half coated with gold nanoparticles - that can be directionally delivered over 22 times of their own diameters in 39 seconds. The opto-thermoelectric field triggers two working states - swimming and rotating - under different laser inputs. Combined with a feedback control algorithm to coordinate swimming and rotating states of the swimmers based on real-time imaging, precise all-optical navigation and target delivery becomes possible.
