Bladder cancer, particularly non-muscle invasive bladder cancer (NMIBC), is the most common malignant tumor of the urinary system. Although platinum-based chemotherapy has shown significant clinical efficacy as a first-line treatment, its therapeutic effect is still limited for patients with lymphovascular invasion (LVI). The formation of LVI is closely related to platelets, which not only hinder drug delivery but also protect tumor cells from chemotherapy-induced cell death and immune attack.

Antibiotics refer to drugs that can inhibit bacterial growth, damage their living environment, and effectively and continuously exert their effects. Antibacterial agents are divided into two categories: organic antibacterial agents and inorganic antibacterial agents. Among them, organic antibacterial agents include natural and synthetic types, while inorganic antibacterial agents mainly include metals, metal ions, and oxides. The commonly referred to antibacterial measures include inhibition, killing, elimination of toxins secreted by bacteria, and prevention. Due to the strong thermal stability, long-lasting functionality, and safety and reliability of inorganic antibacterial agents, coupled with the development of ultra-fine technology in recent years, nanoscale inorganic antibacterial agents can be mass-produced and blended or composite into chemical fibers, ensuring the industrialization of antibacterial chemical fibers.

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:

Are you familiar with nanoscale nickel oxide powder? If you're not, then you're missing out on the wonders that this tiny but mighty powder can provide. Nanoscale nickel oxide powder is a highly sought-after material due to its unique properties and wide-ranging applications.

Particle rearrangement and densification: In liquid-phase sintering, the generation of liquid phase and particle rearrangement are key steps in densification. Small particles have a large specific surface area and surface energy. After the liquid phase is generated, the solid phase is wetted by the liquid phase and infiltrates into the gaps between particles. If the amount of liquid phase is sufficient, the solid phase particles will be completely surrounded by the liquid phase and approximate a suspended state. Under the surface tension of the liquid phase, they will undergo displacement and adjustment of position, thus achieving the most compact arrangement. At this stage, the density of the sintered body increases rapidly

​Nano silver dispersion has been widely used in various fields such as medical science, electronics, and food packaging. The higher the concentration of nano silver dispersion, the stronger the anti-bacterial properties. However, sometimes it is necessary to dilute the high concentration nano silver dispersion to a lower concentration. This article will guide you through the process of how to dilute high concentration nano silver dispersion to low concentration effectively.
