In summary, the field of nanometals has gained widespread recognition for its numerous potential applications, especially in the development of novel catalytic materials. Ruthenium, with its unique and diverse qualities, is one precious metal that has revolutionized several fields such as medicine, energy, and consumer goods with its nanoparticles. As research continues to unfold the properties of these particles, we can expect more applications and innovations in various fields.

​The accurate diagnosis and treatment of acute ischemic stroke (AIS) require high sensitivity and resolution imaging technologies. Unfortunately, such technologies are still lacking in the field. However, on July 4th, 2024, Small reported the development of a Contrast-Enhanced Susceptibility-Weighted Imaging (CE-SWI) technique that is capable of meeting high-precision imaging needs. The technique employs Fe3O4 nanoparticles modified by Dextran (Fe3O4@Dextran NPs), which allows for high sensitivity and resolution imaging of AIS at 9.4T.

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.

​With the continuous development of nanotechnology, silver nano powder has gradually become an important material in the medical field due to its excellent antibacterial and disinfection properties. Especially in epidemic prevention and control and hospital infection control, silver nano powder shows a broad application prospect. This article will discuss the disinfection and sterilization of silver nano powder in medical treatment based on the test experience of the SAT NANO technician Dana.

Scanning Electron Microscope (SEM) is a high-resolution characterization and analysis technique that uses a focused electron beam to scan the surface of a sample point by point, excite secondary electron SE, backscattered electron BSE, characteristic X-rays and other signals, and image them, thereby achieving the microstructure, chemical composition and microstructure of the sample surface. This article will briefly introduce common problems in the SEM testing process, their causes, and corresponding solutions:

In the current era of miniaturization of electronic devices, rapid development of the new energy industry, and continuous improvement of LED lighting power, "heat dissipation" has become a core bottleneck restricting product performance upgrades and lifespan extensions. Traditional thermal conductive materials either have insufficient thermal conductivity efficiency, poor compatibility, and are prone to settling, making it difficult to meet the needs of high demand scenarios. Nano aluminum oxide, with its unique nanoscale structure and excellent thermal conductivity, is becoming a "performance breakthrough" in the field of thermal conductivity, providing efficient heat dissipation solutions for multiple industries such as electronics, new energy, and lighting.
