Hollow structured nanomaterials are promising in the fields of adsorption, catalysis, energy storage and drug delivery/controlled release, owing to their high porosity, large surface area and abundant inner void space. Researchers have developed a new strategy to synthesize single-hole hollow carbon nanospheres.
Collective behavior and swarm patterns are found everywhere in nature. Robots can also be programmed to act in swarms. Researchers have developed collectives of microrobots, which they can move in every formation they wish.
Researchers have developed a point-of-care, portable, rapid, and cost-effective test for clinical diagnosis of sodium, which uses a paper printed colorimetric sensor that is based on Curcumin-functionalized copper (CuC) nanoparticles. They demonstrate that the proposed CuC paper strip can be used for detecting Na+ concentration within the whole physiological range in both blood serum and urine. Sodium is a vitally important electrolyte present in all body fluids and it plays a crucial ...
By combining technologies originally designed for high-energy particle accelerators and astronomy observations, researchers can now for the first time analyze the elemental makeup of samples without damaging them, which could be useful for researchers working in other fields.
Researchers have established a low-cost method of magnetization reversal on perpendicularly magnetized ferromagnets. Not needing an external magnetic field, the method brings reverse magnetization closer to commercial viability.
