Product Overview

 

Mechanical stripping of silicon oxide/silicon substrate single layer molybdenum disulfide is a kind of single layer film material prepared from molybdenum disulfide block by mechanical stripping. The mechanical stripping method, also known as the "tape stripping method", was first proposed by Novoselov et al in 2004 when preparing single-layer graphene. This method uses the friction and relative motion between the tape and the block material to make the thin layer fall off from the block, and uses the adhesive force of the tape to overcome the weak van der Waals force between molecular layers, so as to realize the separation of layer from layer. This method is also suitable for the preparation of single layer or less layer disulfide films. The operation involves using tape to peel off the crystal sheet from the disulfide block, then using another piece of tape to attach to the other side of the disulfide crystal sheet, tearing two pieces of tape to separate the disulfide sheet, resulting in fewer layers. After repeated pasting and ripping the tape, disulfide with few or single layers can be obtained. Finally, it was pasted on the substrate with ultrasonic cleaning and ion cleaning, and the morphology was characterized. The local monolayer disulfide was observed in the microscope. Thin layers of disulfide are easily oxidized in air, and the oxidized material will lose its original properties. Therefore, oxygen isolation is required during long-term storage and use.

Product Features

 

Crystal structure: A single layer of disulfide consists of a central metal atom with two S atoms in a hexagonal arrangement, which is similar in structure to graphene and also has graphene-like properties.

Optical properties: The disulfide prepared by mechanical stripping has excellent optical properties, such as wide gap, high absorption coefficient and strong fluorescence emission, which can study the layer number and fluorescence effect.

Electrical properties: Monolayer disulfide has excellent electrical properties, such as high carrier mobility, low resistivity and high transmittance, which makes it have a wide range of applications in the field of nanoelectronics.

Mechanicl properties: Monolayer disulfide has excellent mechanical properties, such as high elastic modulus, high strength and ultra-thin thickness, making it a potential application in the field of nanomechanics.

 

Application Fields

 

 

Nanoelectronics: can be used to prepare field effect transistors, photodetectors and other electronic devices.

Optoelectronics: can be used to prepare solar cells, photocatalysts and other photoelectric devices.

Catalytic field: Monolayer disulfide has catalytic activity and can be used in catalytic processes such as water decomposition reactions.

Bioimaging: disulfide prepared by mechanical stripping also has certain application potential in the field of bioimaging

Treats and plenty of ball throwing with these doggie toy
Size: Medium (2.5"), Style: Fetch Pack 1
I have actually purchased these twice already. I love the one that glows in the dark but it still got lost in my yard lol. My dog is a big breed half pitt/Labrador so she did chew through one of them already. I play ball with her every single day but I DO have to take them away from her because she will destroy them. They are great to add in treats as well, that was one of the my favorite things about them as well. They do last just if you have an over zealous chewer do not let them keep them for long periods of time. They are a good value for the price. Buy them your dog will love it!

My Female GSD loves
Size: Medium (2.5"), Style: Fetch Pack 1, Size: Medium (2.5"), Style: Fetch Pack 1
Shasta is my smallest. Six in December (2025) along with her brother. She’s 100 lbs and outside, completely ball driven see last picture. Don’t let the size (2.5”) of these Chuck-It balls deter you. If your larger Breed dog has any orthopedic issues, has already torn their ACL etc, one has arthritis but wants to play. This size is perfect! Shazzy was born with several ortho issues. I don’t throw balls distance but right to her. This size and lighter weight assure even when Shazzy is spazzy w excitement, she’ll catch the ball mid air. The green balls are softer, and glow in the dark. In summer we can play well past dusk and I can see them! Her personality shows in the pictures. Playing ball is part of her. These balls are just perfect for her situation. Somehow they disappear, she loves making baskets, puts them in my tractor bucket, or my gardening bucket..then get put in burn pile, trash etc. I keep replacing them because she’d look day and night if we actually ran out!! 🙏✝️👍🏼👍🏼

These paper bowls are actually really sturdy for disposable bowls!
Size: 50 Count, Size: 50 Count
These paper bowls are actually really sturdy for disposable bowls! We use them for everything from cereal and soup to quick toddler meals, and they hold up well without getting soggy or flimsy. I also love that they’re microwave safe, which makes busy days a little easier. Great quality for the price and always handy to keep stocked at home!

My paper bowls of choice.
Size: 50 Count
I have been a return buyer of these bowls and amazon basics plates, as they are sturdy and well made, even for liquids. I think there is a generous quantity for the price. I use for my to go meals on the way to work, so I dont have my whole kitchen accumulating in my car. They are good sized and you can fit a decent serving. Will keep buying.
