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.

Product Features

Layered structure: composed of a layered structure similar to graphite, with weak bonding between layers.

Good lubrication performance: With a low coefficient of friction, it performs well in the lubrication field and can effectively reduce wear between mechanical components.

Excellent electrical performance: It is a semiconductor material with certain conductivity and potential applications in electronic devices.

Good stability: It is not prone to chemical reactions with other substances in the environment and can maintain its structure and properties at high temperatures.

Application Fields

Lubricant: WS¡ãCis a solid lubricant widely used in equipment for high temperature, high pressure, high speed, high load, and transportation in chemically active media.

Petroleum catalyst: WS¡ãCcan be effectively used as a catalyst for hydrogenation, desulfurization, polymerization, reforming, hydration, dehydration, and hydroxylation processes due to its excellent cracking performance, high catalytic activity, and long service life.

Energy storage electrode material: WS¡ãCis a layered material with good thermochemical stability, lithium storage performance, and fast electron transfer rate, which can effectively improve the energy density and structural stability of electrode materials.

Additives for high-performance lubricants: Adding an appropriate amount of WS¡ãCnanoparticles to the lubricant can greatly improve its lubrication performance, reduce friction coefficient, and increase oil film strength.

It feels cheap and works just okay
This product just feels like it was made on the bottom dollar. It is very cheaply made and the doors to the battery compartment are so fragile it feels like they may snap next time I have to change the batteries. There's absolutely no weather proofing so I wouldn't leave it outside in the rain or heat. That being said, it's fine. It stays put on our umbrella and puts out light, albeit not much light.

Functional and easy to install!
Color: Cool White
This umbrella light is super handy! It hinges open to allow installation around the umbrella pole, so you don’t have to remove umbrella from table to add the light. I like that it can be charged with included USB cord or can use regular batteries. The different light settings are also nice depending on how much light you need or want at the time. We’ll be using this quite often when sitting at the table by the pool this summer.

Doggo approved!
Puppy said, "Yes, please." She's a large breed and chews through some toys like nothing. It is May now, and this one is still standing strong. It doesn't have any pieces coming off, so it's quite hard and safe, nothing is coming off for her to eat. It is really resistant to chewing from a Great Pyrenees, and for the price you can't beat it, as it will last months.

Dog tested, dog approved
This is a large, heavy-duty bone. And a great one. My Pitt-mix is very tough on things and can destroy most chew toys in short order. This actually has held up very well to his best attempts. As shown in the picture, after a lot of use over several weeks the most that he's been able to do is to put some small bite marks in it. I'm impressed. That's largely due to the material used. It's a dense, rubbery-type material that's resilient to biting/cutting/tearing. Very solid without being hard. Kind of along the same lines as that used for the popular Chuck-It toys if you're familiar with those (but heavier). I like this softer material better than the nylon bones which he loves but I'm afraid are going to crack a tooth at some point. Has some scent to it but does not have a strong smell. Can't vouch for the flavor but he seems to enjoy it. Again this is large and heavy toy. Probably a little too big/heavy for smaller dogs under say 40lbs or so. Some probably could do it but really better for the bigger dogs. Given how long this one looks like it's going to last, I'd say that it's a very good value. Bottom line - Dog likes it. I like it. Everybody's happy. Great bone. Buy it.

Flavor/Scent May Not Be Very Strong
My pup is picky about toys and the only ones that hold his interest are mostly the scented rubber toys from Playology, They’re great, but expensive, and I was really hoping this would be a cheaper alternative. It really looked like the kind of toy he likes. It’s heavy rubber with a softer texture than the hard toys out there, and it had a lot of surface grooves that lets him grip it with his teeth easily. I gave it to him and he was excited for all of 30 seconds, then he discarded it and hasn’t looked at it since. I suspect the flavor/scent may not be as strong but that’s just a guess. I don’t know if it’s a flaw in the toy or simply a picky pup, so I hesitate to rate this down for that. It does look like a really nice toy and if your dog isn’t a jerk like mine it may be great, and it’s definitely a good price.
