When we talk about future technology, we think of smarter devices, cleaner energy, and healthier lifestyles. Behind these grand blueprints, a seemingly inconspicuous material is silently exerting its power, which is nano nickel oxide.
In the future, with the upgrading of green manufacturing and the demand for functional glass, the application of magnesium oxide will develop towards refinement: on the one hand, the mechanical and optical properties of glass will be further improved by doping with nano MgO (particle size<50 nm); On the other hand, by combining AI driven component design, a new MgO based glass system (such as MgO Li ₂ O-ZrO ₂ low melting point glass) can be developed to adapt to flexible electronics and hydrogen energy storage and transportation applications. The value of magnesium oxide in glass composition is shifting from a "performance regulator" to a "functional enabler", driving the evolution of glass materials towards higher performance and wider scenarios.

Copper is different from metals such as aluminum and nickel in that it is difficult to form a dense and stable intrinsic passivation layer on its surface. Therefore, the exposed copper surface will be continuously oxidized and corroded by oxygen and water vapor in the air. The smaller the particle size and larger the specific surface area of copper powder, the easier it is to rapidly oxidize to produce products such as cuprous oxide (Cu2O) and copper oxide (CuO). This oxide insulation layer significantly reduces the conductivity of copper powder and hinders particle sintering connection, resulting in degradation of the performance of the conductive paste.
Copper nanoparticles have attracted a lot of interest in recent years due to their interesting properties, low-cost preparation, and many potential applications in catalysis, cooling fluids, or conductive inks. In this study, copper nanoparticles were synthesized by chemical reduction of copper sulfate CuSO4 and sodium borohydride NaBH ₄ in water without inert gas protection.
