Researchers have found that ultrasmall Au25 - gold - nanoparticles have a positive effect on inflammatory bowel disease in mice, with no side effects observed.
Researchers have developed a contact lens that can capture and detect exosomes, nanometer-sized vesicles found in bodily secretions which have the potential for being diagnostic cancer biomarkers.
Researchers have developed an anti-freezing degradable triboelectric nanogenerator with high electrical output property using a novel biocompatible zwitterionic network hydrogel.
Researchers have developed micro-light-emitting diodes (LEDs) to construct an auxetic meta-display - a distortion-free stretchable display based on auxetic metamaterials.
Scientists propose a novel double slot structure for high-performance photodetection, taking advantages of both silicon photonics and plasmonics. With the optimized structural parameters, the double slot structure significantly promotes graphene absorption while maintaining low metallic absorption.
Researchers report the development of a nanoparticle that acts as a heater and a thermometer. Inserting the nanoparticle in living cells results in a heat spot that, by switching it on and off, enables the controlled modulation of local cellular activities.
Researchers have 3D printed a dual-phase, nanostructured high-entropy alloy that exceeds the strength and ductility of other state-of-the-art additively manufactured materials.
The technique is expected to contribute to catalyst design based on accurate understanding of the photocatalytic reaction through an analysis method that helps understanding the electron excitation phenomenon and transition path.
Researchers show proof of concept that running an electrical current through a novel two-dimensional material could control the magnetic state of a neighboring magnetic material without the need of applying an external magnetic field.
Mesoporous carbon spheres facilitate charge transport and high surface charge densities in triboelectric nanogenerators for a 1300-fold higher output current.
The defenses of the body's immune system tend to destroy synthetic nanoparticles and frequently they are captured and removed from the body within few minutes. This, of course, is a major barrier to the use of nanotechnology in medicine. In order to evade the host immune response, researchers are demonstrating that the combination of nanomaterials and biomimetic strategies can change diverse nanomaterials from 'distinguishable state' to 'camouflage state' and thereby improving ...
Crystals consisting of wildly mixed ingredients - so-called high-entropy materials - are currently attracting growing scientific interest. Their advantage is that they are particularly stable at extremely high temperatures and could be used, for example, for energy storage and chemical production processes.
One convenient way to manipulate nanoscale objects with remote controllability is actuation and propulsion by light, which is largely based on optical and photothermal-induced forces. Unfortunately, the output of optical and photothermal-induced forces is small and speed is slow. This changes with a novel and intriguing nanoactuation system: plasmonic nanodynamite. This system can be optically triggered to eject gold nanobullets with an initial speed of up to 300 m/s.
Researchers have observed, for the first time, electric gate-controlled exchange-bias effect in van der Waals (vdW) heterostructures, offering a promising platform for future energy-efficient, beyond-CMOS electronics.
