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.


Technical Parameter

Thickness: 1-10 layers

Size: 50nm-1μm

Concentration: 1mg/mL

Solvent: Water-Ethanol,NMP,DMF,IPA

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.

Totally Sweet
Format: Kindle
🔥OmegaVerse 🔥Single Mom 🔥Scent Match 🔥Emotional Trauma Well written, emotional omegaverse about a single mom of 2 with an ex-Alpha boyfriend that found his Omega and ditched his family. Cammie has a meet cute with Reid and Finton separately but they both find her to be their scent match. This book is totally sweet with lots of drama but lots of proving to Cammie that she is loved and wanted. My Personal Ratings: 5 Stars: Loved it! Couldn’t put it down or obsessed about it while needing to get to the end of it. Had to share some bits with my hubby!! Usually read in less than 2 days cause a girl has got to sleep sometime. Will be reading everything this author has to offer and most likely reread the series as next books in the series are released. 4 Stars: Really Good. Whether the story drew me in or a specific character, will definitely continue the series and look into more books by this author. 3 Stars: Enjoyed something about the book, whether it be the storyline or a character but also may have not liked something. Sometimes the book is great but needs some TLC from an editor. May or may not continue the series.

Read it!!! It's so good!
Format: Kindle
I will reccomend this book to anyone and everyone who is looking for an omegaverse book to read! The rabbit hole of male omega books this one sent my mood reading self down was crazy! 🤭 I could not have loved Finn more! He was the sweetest omega, making sure Cammie was comfortable each step of building a relationship with him and Reid. He was so good with the kids even though Ben was a little rough around the edges. Cammie's fears were all justified but the way she learned to trust her new pack was sweet! They just continued to show up and her sister was hilarious! Being a mom and thinking of her littles but also finding her own happiness was such a sweet journey for her 💖 lets just talk about the kids for a second and say Em is a spitfire and I LOVE her and Ben sweet Ben just wants to protect his Mama but needs love, Reid does such a good job stepping up! And the 'gift' at the end had me in tears!! 🥹 Without giving too much away that is why I think sweet Finn is my favorite of all male omegas I have ever read! His way with words no matter what he is using them for, declarations of love, pep talks, or advice he really just knows what needs to be said 💖

I wanted to like this more than I did
Format: Kindle
This started off so well! I thought it was going to take Lola on a run for her money but it ended up getting weird. I liked the writing but there was just too much spice which I didn't think was possible for me. There were too many times that the writing felt weird or the situations too outlandish and unrealistic. I had to skim through a lot of the later half. It might just be the dynamic between the characters that didn't work for me so I'll give this author another go.

love love love!!
Format: Kindle
Unwanted is the perfect hurt/comfort romance read. I LOVE an OV romance where the beta is the center of the story and Song delivers a heartfelt story of a single mom to 2, burned by her alpha-hole ex starting her life over in the small town of Knotty Pines. Reid and Finn are an alpha/omega pair who’ve been together since they scent matched as teenagers, they’ve always known someone was missing in their lives and they’ll stop at nothing to prove to Cammie that her, Em & Ben are everything they always wanted. I couldn’t put this one down - Song tugs at your heart strings, and gives you vulnerable, real and lovable characters with depth and relatability. The book is so well paced, detailed to perfection without overdoing it or straying, I really honestly loved the flow and details in this story and the banter and humor had me smiling throughout this read. This was the perfect hurt/comfort, who did this to you, fated mates, stop at nothing to get the girl romance that I’ll be recommending for the foreseeable future!!

Oh this was adorable and cozy and spicy
Format: Kindle
Oh this was adorable and cozy and spicy and I had so much fun with this book! The relationship between Cammie, Finn and Reid is good. I love how doting both men are of her and her kids, always providing them with a safe space to be themselves. They were patient with Ben and I loved seeing that represented in this book. The plot was done well and it was well paced with quiet, family moments as well as drama to keep us on our toes. I do wish we'd gotten more moments just between Finn and Reid to showcase their strong relationship (they've been together for two decades!) and while we got something, both men were first and foremost focused on Cammie. It makes sense why this was, there was a lot of hurt that needed to be soothed and I'm glad she is treated like the queen she is, but I did yearn for more of the alpha-omega couple.
