​The preparation of SEM nano powder samples usually requires the following steps:

A groundbreaking study published in Advanced Functional Materials on February 16, 2025, unveiled a novel MXene thin film protected by reduced graphene oxide (rGO), termed rGM. This innovative film boasts exceptional charge transfer capabilities and the remarkable ability to stay stable in the ambient air. The protective rGO layer effectively shields the conducting layer of MXene from air oxidation, significantly enhancing air stability. After 40 days of exposure to air at 25°C and 40% relative humidity, the membrane resistance of the rGM film (135.9±2.3Ω/sq - 312.6±4.5Ω/sq) showed negligible amplification compared to the pure MXene film (145.0±2.3Ω/sq - 2,152.8±6.8Ω/sq).

When it comes to powdered materials, density is an essential parameter that determines their physical and chemical properties. Different methods are employed to measure powder density, including loose bulk density, tapped density, true density, apparent density, bulk density, and compacted density. This article will discuss these parameters, and how they affect the properties of powdered materials.

There are different methods to measure the particle size of powders, depending on the size range of the particles and the desired accuracy of the measurement. Here are some common techniques:

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.

Small particle alumina powder has a wide range of applications in ceramics, chemical engineering, electronics and other fields due to its unique physical and chemical properties. However, in practical applications, small-sized alumina powder is prone to agglomeration, which refers to the phenomenon of powder particles adhering to each other and forming larger aggregates during storage, transportation, or use due to various factors. Causing its performance to be affected. The agglomeration phenomenon can lead to poor flowability and reduced dispersibility of the powder, affecting product quality.
