Exceptional Properties for Advanced Applications

Monolayer tungsten disulfide exhibits a direct band gap (~2.1 eV), excellent dimensional stability, and high mechanical strength at the nanoscale. Its atomically smooth, non-porous structure and high in-plane thermal conductivity make it a prime candidate for next-generation semiconductors, flexible electronics, and photodetectors. Due to its unique physical and chemical properties, it also finds roles in catalysis, lubrication, and energy storage devices.

Safe Handling and Optimal Storage

WS nanosheets should be stored in an inert atmosphere to maintain their stability and high purity. Moisture exposure must be avoided to prevent degradation or altered performance. Although toxicity is low, standard safety protocols outlined in the MSDS should be followed during handling. The product remains stable and reliable under recommended storage conditions, ensuring longevity for research and industrial needs.

FAQs of Nano Size Monolayer Tungsten Disulfide:

Q: What are the recommended storage conditions for nano-size monolayer tungsten disulfide?

A: Nano-size monolayer tungsten disulfide should be kept in an inert atmosphere, such as argon or nitrogen, and away from moisture. This ensures its stability and preserves its chemical integrity for long-term use.

Q: How is nano-size monolayer tungsten disulfide typically synthesized?

A: This material is commonly synthesized via chemical vapor deposition (CVD), mechanical exfoliation, or liquid phase exfoliation methods. These processes yield high-purity, monolayer-thick WS nanosheets with uniform size and shape.

Q: What are the main applications and benefits of monolayer WS nanosheets?

A: Monolayer WS nanosheets are valued for their direct band gap and semiconducting properties, making them suitable for electronics, optoelectronics, sensors, catalysis, energy storage, and lubrication. Their high mechanical strength and excellent thermal conductivity further expand their application potential.

Q: When should I use monolayer tungsten disulfide instead of bulk WS?

A: Monolayer tungsten disulfide is ideal for applications requiring direct band gap semiconductors, flexibility, and atomically smooth surfaces, such as nanoscale transistors, photodetectors, and flexible electronic devices. It offers distinct properties not found in bulk WS.

Q: Where can monolayer tungsten disulfide be sourced in India?

A: This nanomaterial is available through various channels in India, including dealers, exporters, importers, manufacturers, producers, retailers, suppliers, traders, and wholesalers. It can be supplied in powder, dispersion, or film form according to application needs.

Q: What safety measures should be observed when handling WS nanosheets?

A: While WS poses low toxicity, users should adhere to personal protective equipment guidelines and relevant MSDS recommendations. Effective ventilation and avoidance of inhalation or skin contact are advised during material processing or application.
