Product Features

Excellent mechanical properties: with extremely high strength and toughness. For example, its theoretical strength can reach tens or even hundreds of times that of steel.

Excellent electrical performance: can exhibit good conductivity, depending on aspect ratio, structure, and preparation method.

Good thermal performance: high thermal conductivity, capable of effectively transferring heat.

Large specific surface area: This makes it potentially applicable in fields such as adsorption and catalysis.


Application Fields

1. Composite material reinforcement: Multi walled carbon nanotubes have high strength and toughness. Adding them to matrices such as plastics, rubber, and metals can significantly improve the mechanical properties of the material, such as strength and stiffness. For example, grafting carbon nanotubes onto the surface of carbon fibers to obtain a multi-level structure can enhance the interfacial interaction with organic matrices and the mechanical properties of composite materials.

2. Electronic devices: Although their conductivity is not as single and excellent as single-walled carbon nanotubes, they still have good conductivity and can be used to manufacture high-performance conductive inks, sensors, flexible displays, and other electronic devices.

3. Electrode materials: Can be used as electrode materials for lithium-ion batteries and supercapacitors to improve energy storage and power output capabilities.

4. Catalysts and catalyst carriers: They can serve as catalysts themselves. It can also serve as a catalyst carrier, providing more active sites for catalytic reactions and enhancing catalytic performance due to its large specific surface area and unique structure. For example, acidified multi walled carbon nanotubes can be used as carriers to load composite inorganic salts, resulting in solid acid catalysts with superior catalytic effects than single component iron sulfate.

5. Energy field: In addition to the applications mentioned earlier in batteries, it can also be applied to hydrogen storage materials. The unique hollow structure and nanometer diameter of carbon nanotubes provide favorable conditions for hydrogen storage.

6. Absorbing materials: They have a certain ability to absorb electromagnetic waves and can be used to prepare absorbing materials. They have potential applications in military stealth, electromagnetic shielding, and other fields.

7. In the field of biomedicine: Its unique hollow structure and nanometer diameter can provide space for accommodating drugs, achieve high drug loading, and can pass through cell membranes and various biological barriers to deliver drugs to the inside of cells. In addition, it can effectively reduce the release rate of drugs and improve the sustained release effect.

8. Research field: commonly used in various scientific studies to help researchers explore the properties and potential applications of nanomaterials.

The paper quality is pretty good as well
Format: Hardcover
I bought this book to replace a compact-version because the font was too small for my eyes. This one is larger in font and has a bit more info. per entry than the compact one. The paper quality is pretty good as well. I recommend it as a resource to have with your desk reference collection.

Soothing, moisture-locking oral coat that eliminates morning dryness without burning your mouth
Flavor Name: Mint, Size: 33.8 Fl Oz (Pack of 1)
Standard alcohol-based mouthwashes give a powerful blast of burning freshness, but they completely dry out your tissues and make a lack of natural saliva much worse. Biotene Dry Mouth Oral Rinse fixes this issue entirely by skipping the harsh astringents. It uses a specialized mouth-moisturizing system packed with hydrating humectants like glycerin, xylitol, and sorbitol. This combination creates a slippery, lubricating layer over your gums and cheeks that mimics your natural saliva to keep your mouth comfortable and damp. The daily utility of this formula is perfect if you struggle with persistent stickiness, difficulty swallowing dry foods, or a scratchy throat. It provides immediate relief that keeps working for up to four hours, soothing sensitive oral tissue and actively fighting the bacteria that cause chronic bad breath. The gentle, sugar-free fresh mint flavor leaves you feeling genuinely clean and maintains a healthy, balanced pH level in your mouth to protect your teeth from potential cavities. It is a fantastic, non-burning formula to use right before bed or throughout the day to completely wash away that uncomfortable, parched feeling and wake up with lasting comfort.
