This is the first time that three properties, being piezoelectric, photothermal and antioxidant, have been combined in a single organic structure measuring 500 nanometres.

These are the new nanoparticles designed and produced by a research group at the Italian Institute of Technology (IIT-Istituto I

Silver nanoparticles with diameters of ~10 nm deliver the best performance as electrocatalysts. The silver particles are sprayed onto the electrode together with a conductive carbon powder. The ideal mixture consists of 20 per cent by mass silver and 80 per cent by mass carbon powder. This image was taken using a transmission electron microscope (TEM). © HZB Via electrolysis, CO₂ can be reduced to CO, a raw material for further chemical products such as fuels. Within the Gre

image: Researchers have observed string-breaking dynamics on a quantum simulator that could help probe questions related to the Big Bang. This is an artistic rendering of string-breaking. Credit: Emily Edwards, Duke University A research team led by faculty at the Duke Quantum Center (DQC) has observed string-breaking dynamics related to particle-antiparticle formation on a quantum simulator, one of the first in the quantum-physics field. This approach, described in the journ

Fig.1 Device illustration. Conceptual illustration of an integrated quantum photonic circuit in which diamond nanobeams containing quantum emitters and spins are embedded within integrated photonic devices. Credit: Shuo Sun et al. Quantum photonic chips could one day help power quantum networks and quantum computers, but building them has faced a stubborn materials problem. The best materials for hosting quantum emitters are often not the same materials that are best for maki

Scientists have shown that a material treated for 40 years as a uniform, textbook superconductor is in fact a patchwork of different crystal structures throughout its bulk, using one of the latest 3D imaging techniques to see deep inside the crystal for the first time. High-temperature superconductivity is widely regarded as one of the most significant scientific discoveries of the past 40 years. It promises technologies built on electricity that flows with zero resistance an

In this illustration, photons hit a strip of superconducting wire, disrupting the electric current and registering an electric pulse. Each pulse tells researchers about the light that has hit the detector, which is beneficial for applications like biomedical imaging and astronomy.
