The fusion of nanotechnology and textile engineering has led to the development and improved performance of multifunctional smart materials in various application fields. One recent breakthrough is the one-step synthesis of AgNPs/CNTs spray-coating solution, which is used to anchor silver nanoparticles on multi-walled carbon nanotubes and apply them onto nonwoven fabric to create multifunctional smart textiles.

With the development of integrated circuit (IC) technology, the scaling of silicon-based metal oxide semiconductor (MOS) field-effect transistors (FETs) is approaching their fundamental physical limits. Carbon nanotubes (CNTs) are considered promising materials in the post silicon era due to their atomic thickness and unique electrical properties, with the potential to improve transistor performance while reducing power consumption. High purity aligned carbon nanotubes (A-CNT) are an ideal choice for driving advanced ICs due to their high current density. However, when the channel length (Lch) decreases below 30nm, the performance of single gate (SG) A-CNT FET significantly decreases, mainly manifested as deteriorating switching characteristics and increased leakage current. This article aims to reveal the mechanism of performance degradation in A-CNT FET through theoretical and experimental research, and propose solutions.

Epoxy floor coating is commonly used for decorating and protecting the floors of buildings. However, the surfaces of these coatings often generate static electricity, which attracts dust and bacteria. The effect of static electricity on human health and the dust and conductivity of equipment cannot be ignored. Therefore, the development of anti-static epoxy floor coatings has become a hot research topic today. This article will explore the application of carbon nanotube powder in anti-static epoxy floor coatings.

On unsaturated metal sites of metal oxides or semiconductor oxides (such as Ti4+, Fe3+), water molecules first adsorb in molecular form, followed by O-H bond cleavage, resulting in bridge or terminal hydroxyl groups (M-OH) and surface hydrogen atoms. The thermodynamic driving force of this process comes from the strong Lewis acidity of metal ions, making water molecules easy to dissociate. Both experiments and DFT calculations indicate that surfaces covered with low oxygen tend to dissociate and adsorb, while surfaces covered with high oxygen tend to adsorb molecules.

Scanning electron microscopy can be divided into thermal electron emission type and field emission type according to the different ways of electron generation. The filament used for thermal electron emission type is mainly tungsten filament electron microscopy. Field emission type The distinction between hot field emission and cold field emission.

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:
