The crystal structure of nano iron oxide is hexagonal, and the lattice parameters change with the decrease of particle size. When the particle size is large (usually larger than tens of nanometers), iron oxide exhibits a typical α- The Fe2O3 structure, also known as hematite structure, is red in color. This is because typical α- The Fe2O3 structure has a high reflectivity for visible light, absorbing shorter wavelengths (blue-green) in visible light, leaving only longer red wavelengths observed.

Osteoarthritis (OA) is a prevalent disease characterized by subchondral bone fracture, and there is no accurate and specific treatment yet available. Recently, the research team has synthesized a new multifunctional scaffold that can potentially solve this problem. Using photo-polymerized modified hyaluronic acid (GMHA) as a substrate and hollow porous magnetic microspheres (HAp-Fe3O4) as the base, they designed a scaffold with optimum properties for subchondral bone repair.

Researchers have made a breakthrough in the development of carbon nanotube (CNT) reinforced aluminum composites by utilizing ultra-short CNTs with unique intra-crystalline dispersibility. The nanoscale carbon nanotubes are uniformly distributed within the ultra-fine aluminum grains. When compared with typical CNT/Al composites with inter-granular CNT dispersion, this intra-crystalline carbon nanotube/aluminum composite has a stronger ability to anchor and maintain dislocations, resulting in enhanced strength and ductility. This innovative intra-crystalline dispersal strategy provides a new avenue for developing strong and tough nanocarbon reinforced metal-based composite materials. The research has been published recently in a prestigious academic journal.

To disperse metal powder into a dispersed liquid, several methods can be used, depending on the type and properties of the metal powder and the desired application of the dispersed liquid. Here are some common methods:

The integration of science and technology has brought mankind a stunning innovation, Precious Metal Nanoparticle Iridium Powder, which is one of the most used valuable elements in industrial and non-industrial sectors. This stunning product is not only precious, but it can also provide outstanding applications in different technology-related fields.

Nano boron carbide and ultrafine boron carbide powder were prepared by variable current laser ion vapor phase method. Boron carbide, also known as black diamond, has a molecular formula of B4C and is usually a gray black micro powder. It is one of the three hardest materials known (the other two being diamond and cubic boron nitride). Hard black glossy crystal. The hardness is lower than industrial diamond, but higher than silicon carbide. Compared to most pottery, it has lower fragility. Has a large thermal neutron capture cross-section. Strong chemical resistance. Not susceptible to corrosion by hydrogen fluoride and nitric acid. Dissolved in molten alkali but insoluble in water and acid.
