Inducing surface strain to CeO2/Mn3O4 heterostructured nanocrystals can enhance antioxidant properties.
Researchers discover a quantum fluid - fractional quantum Hall states, one of the most delicate phases of matter - in a monolayer 2D semiconductor; finding could provide a unique test platform for future applications in quantum computing.
Scientists provide new insights into the interactions of layered materials with laser and electron beams.
The concept of nanostructuring of battery electrodes is not new; it has been frequently employed to improve the charging speed and, in some cases, stability of Li-ion electrodes. Researchers now demonstrated 3D-interconnected Ni nanowire meshes as current collectors and structural scaffolds for building nanostructured Li-ion electrodes. This material exhibits a semi-ordered structure and is characterized by some of the highest combined porosity and surface-to-volume ratio among macroporous metals.
Researchers have developed a human cell 'membrane on a chip' that allows continuous monitoring of how drugs and infectious agents interact with our cells, and may soon be used to test potential drug candidates for COVID-19.
Researchers have developed a novel direct growth method of vertically orientated nanocavity arrays to generate plasmonic structural colors, which feature wide gamut, improved color saturation, excellent stability in ambient condition and mass-production scalability.
Researchers have come up with a novel electrode that could greatly improve the stability of perovskite solar cells, the most promising candidate for the next generation solar cells due to their low cost and high power conversion efficiency.
Researchers have unveiled a novel material that could enable major leaps in the miniaturization of electronic devices.
Researchers using a strategy called strain-engineering in 2D materials now say new types of cathodes, suitable for advanced energy storage, can be developed using beyond-lithium ion batteries.
Scientists have found microscopic structures in perovskite crystals that can guide the charge transport in the solar cell. Clever alignment of these electron highways could make perovskite solar cells even more powerful.
Previously, researchers discovered that the well-known coffee-stain effect is caused by a remarkable mechanism, showing avalanche-like behavior of particles in a fluid. They now show how to prevent the ring-shaped coffee-stain and get a uniform distribution of the particles instead.
Easily produced, nature-like nanostructures of cobalt phosphide are highly effective catalysts for the electrolysis of water.
Researchers show that a nanoporous MoS2 membrane allows a higher water flux compared with other 2D materials such as graphene, boron nitride and phosphorene. The team dug deeply into the physical reasons behind why MoS2 performed better than other two-dimensional materials in water desalination processes. Through molecular dynamics simulation, they found out that water density near a MoS2 membrane is lower compared to that near other materials, which indicates that water molecules were more likely to transport through the membrane instead of accumulating around it.
An international team of researchers has demonstrated an innovative technique for increasing the intensity of lasers. This approach, based on the compression of light pulses, would make it possible to reach a threshold intensity for a new type of physics that has never been explored before: quantum electrodynamics phenomena.
Researchers have developed a safer and more efficient way to deliver a promising new method for treating cancer and liver disorders and for vaccination -- including a COVID-19 vaccine.
Scientists sought to form longer-lifetime response complexes in a hydrogel and use those longer responses to produce unique reactions in the hydrogel.
Researchers demonstrated novel ways to design and build materials for controlling light. The new materials have two layers of metasurfaces.
Scientists have pioneered a new technique to produce arrays of sound produced entirely by heat.
Researchers have developed a new system of electrodes that can be implemented into our clothing and withstand our daily routines.
A new study finds that carbon nanotube film has a combination of thermal, electrical and physical properties that make it an appealing candidate for next-generation smart fabrics.
