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.

Everyday use
Size: 11-Piece Set
I've used these pans for about a year now and they are still holding up great. For everyday abuse they do not faulter. Plus they clean easy. These pans are a great way to get name brand quality without breaking the bank.

Solid design, long lasting, healthy surface for cooking
Size: 11-Piece Set
I bought this exact set in 2021. I am buying more. With the number of reports about the dangers of pans made with non stick coating I decided i would only use cast iron or stainless steel going forward. These are “amazon brand” but I can say after years of use and abuse they are standing the test of time. Multiple moves, toddlers, rough use and they are all fully functional and work great. I LOVE the teardrop handles. It makes it so easy to hold the handle and the hanging holes on the handles are large allowing you to hang it more places on more things you may already have set up in your kitchen. I think anyone who is looking to get away from cheap, chemically pans off the rack should look at this set!! I have 4 years of proof they are not junk but a great long lasting items that seem to be well made. Higher price than buying a $10 pan at walmart but you get so many pots and pans with lids that will last a lifetime. You can also use stainless steel to cook in the oven so more functionality than most pans and pots you buy of the rack. You will just need to learn how to cook with stainless steel pans (check YouTube lots of instruction there).

Very pretty cookware
Size: 11-Piece Set
This is nice quality cookware for a great price. I have seen cooking shows that tell how to cook in stainless steel without it sticking. Unfortunately, my food still sticks. If I use a lot of oil, it isn’t so bad. One cooking show host says if you get it real hot before you add the oil, it won’t stick. It sticks. I am trying to get away from using Teflon because they say we have a lot of Teflon in our bodies from our cookware. I still go back to my Teflon a lot. But the cookware is very pretty, a nice weight, and cleans up fairly easily. I do soak the skillet before I clean it. I don’t have to do a lot of scrubbing. The sauce pans are great.

Cooks well, cleans easily
Size: 15-Piece Set
Bought this to replace old nonstick cookware. Looks good and not too heavy. Pot handles are cool enough to hold near the ends but tend to warm up close to the pot itself. Using on a gas range – heat spreads quickly and cooks. Best on low heat. Some sticking problems with food like cereal, lower heat advised. Glass lids are very handy with steam outlet. Have not used all of them yet, but they store and stack easily and I was looking for a good size stock pot and this should suffice. Not as heavy as other stainless steel cookware. Price reasonable for the number of pieces included.So far I am very pleased with this purchase.

Heat up well before use for "non-stick".
Size: 11-Piece Set
I really l Iike these stainless steel pots. I had to learn the trick to using them, and that is to make sure they are heated up properly before using. This makes them "non-stick" and your food won't stick to the bottom of the pot, especially if you're frying it. Also follow the manufacturers instructions and "season" the pots after you receive them, by coating the insides with oil and heat them up. They cook really well, are light weight, easy to use, easy to clean, very sturdy, shiny surface, and holds heat after you've finished cooking. Also, don't use harsh scrubbers in them because it will scratch the surface. Scotch Brite Scour Pads work well in these pots. If you scratch them, use the green Scotch Brite Scour Pads to polish the scratch marks out. Enjoy them!
