Product Overview

Tungsten disulfide (WS2) is a type of transition metal sulfide (TMDC) with a graphene like layered structure, where the layers are stacked together by weak van der Waals forces. Single layer WS2 is composed of three layers of atoms, with the atomic planes of W and S arranged in a hexagonal array. The W atoms are sandwiched between the two layers of S atoms, forming an S-W-S atomic layer structure with a "sandwich" structure. Multi layer or block WS2 is composed of single layers stacked together. Depending on the stacking method of the single layers, WS2 has three crystal structures: 1T, 2H, and 3R.

The synthesis methods of WS2 are mainly divided into two categories: "top-down" stripping method and "bottom-up" method. The "top-down" exfoliation method includes micro mechanical exfoliation, liquid-phase exfoliation, and lithium-ion intercalation, mainly using physical means to exfoliate the bulk WS2 into a single-layer or few layer layered structure. The "bottom-up" method includes chemical vapor deposition, hydrothermal method, and high-temperature thermal decomposition method, mainly using chemical means to grow atoms and molecules into nanoscale thin films and granular WS2 under certain environmental conditions.

XF210 WS2 dispersion was prepared by liquid-phase exfoliation method, resulting in a 2H phase. According to different application requirements, various solvents such as water ethanol, DMF, NMP, etc. can be selected as dispersion media.

Product Features

Single crystal and high purity: The liquid-phase exfoliation method can prepare single crystal tungsten disulfide nanosheets with a pure 2H phase structure.

Good dispersibility: The dispersion of tungsten disulfide nanosheets obtained by liquid-phase exfoliation method has good dispersibility and can stably exist in various solvents, such as water ethanol, DMF, NMP, etc.

Multifunctionality: Tungsten disulfide nanosheets have enhanced electronic, optoelectronic, sensing, and catalytic properties, making them suitable for fields such as electrochemical energy storage, electrochemical catalysis, device manufacturing, and biological research.

Low friction coefficient and high compressive strength: As a lubricant, tungsten disulfide has better performance than molybdenum disulfide, with lower friction coefficient and higher compressive strength.


Application Fields

Semiconductor materials: Tungsten disulfide nanosheets are widely used in the semiconductor field due to their unique electronic properties.

Electrochemical energy storage: In batteries and fuel cells, tungsten disulfide nanosheets can be used as electrode materials to improve energy density and cycling stability.

Catalyst: Due to its high specific surface area and active sites, tungsten disulfide nanosheets exhibit excellent catalytic performance in catalytic reactions.

Biological detection and medical applications: In the biomedical field, tungsten disulfide nanosheets can be used for biological imaging, drug delivery, and biosensors.

Yes, Black Cowboys in NYC!
Format: Hardcover
I just read this book with my granddaughter on Libby and ordered it immediately from Amazon. (I will also order it in a Spanish version for my granddaughter to bring to her school). My husband is a musician who performed at the “Atlantic Antic” in Brooklyn many, many years ago. He told us about the Black Cowboys in Brooklyn who trotted up to his concert on Atlantic Ave. “It was surreal,” he said, “to see black cowboys on horseback in New York City!”

thrilling ride of a book
Format: Kindle
Beautiful... I love the tenderness of the father-daughter relationship, and the gentle love between rider and horse, contrasted with the raw thrill of the pre-dawn adventure. This book manages to portray something so specific - an urban horseback ride - with such deep and universal appeal.

Beautiful book!
Format: Hardcover, Format: Hardcover
This book perfectly exemplifies how soft and simple can be so magical. The lyrical language laden with sensory details, paired with the vibrant visuals, makes for an absolute treat of an experience! The father-child time at night immediately reminded me of OWL MOON and just like owling, urban horseback riding is something we’ve never experienced personally, so it was especially thrilling to experience it with my children through this book. I also love that this book is a celebration of Black culture and joy. Finding the universal through the specific is the key to any good story, and the author has a real knack for it. Just like the Abuelita in this story, my mother is the first to wake up, and we find her nestled in her chair with a cup of coffee. And the description of the little girl’s kiss on her Abuelita’s papery cheek brought back memories of my own grandmother’s papery cheek – something I miss very much. Picture books really are for everyone. All the starred reviews are so well-deserved and I’d be very surprised if this book didn’t win awards. Highly recommend!
