Product Overview

Carbon nanotubes are simple substances composed of carbon atoms and can be regarded as hollow tubular structures formed by the curling of graphene. On the surface of carbon nanotubes, the carbon atoms are bonded to each other in the form of sp2 hybrid orbitals, which are arranged as hexagonal graphite layers. In theory, this regular hexagonal structure is perfectly evenly distributed over the entire surface of the carbon nanotubes. Topologically, the common structure and properties of graphene and carbon nanotubes are one of the important factors for their similarity. However, due to the curvature of the graphite layer in the carbon nanotubes, coupled with the defects that may occur during the growth process, the sp3 hybrid phenomenon may occur in the six-membered ring structure on the surface of the carbon nanotubes, resulting in the emergence of five-membered rings or seven-membered rings. Carbon nanotubes can be divided into single-walled carbon nanotubes, double-walled carbon nanotubes and multi-walled carbon nanotubes according to the graphite sheets with different number of layers.

Product Features

 

Multi-walled carbon nanotubes have many unique properties:

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

Excellent electrical properties: Can show good electrical conductivity, depending on length-diameter ratio, structure and preparation method.

Good thermal performance: high thermal conductivity, can effectively transfer heat.

Large specific surface area: This makes it a potential application in adsorption, catalysis and other fields.


Application Fields

 

1. Composite material strengthening: multi-wall carbon nanotubes have high strength and toughness, adding them to plastics, rubber, metal and other substrates can significantly improve the mechanical properties of the material, such as strength, stiffness and so on. For example, the multistage structure obtained by grafting carbon nanotubes on the surface of carbon fiber can enhance the interfacial interaction with organic matrix and the mechanical properties of composite materials.

2. Electronic devices: Although its electrical conductivity is not as single and excellent as that of single-wall carbon nanotubes, it still has good electrical conductivity and can be used to manufacture high-performance conductive inks, sensors, flexible displays and other electronic devices.

3. Electrode material: It can be used as electrode material for lithium-ion batteries and supercapacitors to improve energy storage and power output.

4. Catalyst and catalyst carrier: itself can be used as catalyst. It can also act as a catalyst carrier, and because of its large specific surface area and special structure, it can provide more active sites for catalytic reactions and improve catalytic performance. For example, acidified multi-walled carbon nanotubes can be used as a carrier to support composite inorganic salts, and the solid acid catalyst produced has better catalytic effect than single-component iron sulfate.

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

6. Wave absorbing material: It has a certain absorption capacity for electromagnetic waves, and can be used to prepare wave absorbing materials, which has potential application value in military stealth and electromagnetic shielding.

7. Biomedicine field: Its unique hollow structure and nanotube diameter can provide space for containing drugs, can achieve a high drug load, and can pass through cell membranes and a variety of biological barriers to deliver drugs to the interior of cells. In addition, it can effectively reduce the drug release rate and improve the sustained release effect.

8. Scientific research: It is often used in various scientific research to help researchers explore the properties and potential applications of nanomaterials.

Charming and Summery, But Longer Than It Should Be
Format: Paperback
⭐️⭐️⭐️💫 (3.5 Stars) I listened to Every Summer After on audio, and at first, it really felt like it had the potential to be a solid 4-star read for me. The beginning is charming, easy to sink into, and definitely has that cozy, nostalgic summer atmosphere that so many readers love. It’s a cute, pleasant story with a smooth flow, and the type of book you can listen to without needing to focus too deeply. However, as the story went on, the pacing became a real issue. At around ten hours, this audiobook felt unnecessarily long. The plot didn’t have enough depth or twists to justify that length, and I honestly think it would have been a much stronger book if it wrapped up closer to the seven-hour mark. Around the midpoint, I found myself losing interest at times simply because the narrative stretched itself thin. When it comes to the writing itself, Carley Fortune keeps things very simple. There’s nothing particularly inspiring, profound, or memorable about the prose. It’s straightforward and easy to follow, but it doesn’t stand out, and I wouldn’t say it’s developed enough to be considered a distinct “writing style.” It does the job, but it never elevates the story or adds emotional depth the way some authors can. I also didn’t fall deeply in love with the characters. They were fine, but not the type that stay with you after the book is over. Because the character connection never fully clicked for me, the slower pacing felt even more noticeable, and some of the emotional beats didn’t land as strongly as they were intended to. Overall, Every Summer After is an easy, pleasant listen — perfect if you’re looking for something light, summery, and uncomplicated. While the overly long runtime, very simple writing, and limited emotional connection kept it at 3.5 stars for me, it’s still a sweet story that delivers exactly what many readers look for in a nostalgic summer romance. I’m still open to exploring more of Carley Fortune’s books, and I’m curious to see how her other stories compare!

a perfect summer romance
Format: Paperback
this book was phenomenal!! i loved every page and i fell in love with the story and characters. it’s told in past and present timelines over the course of six summers and one weekend 12 years later. you get small town, second chance romance, childhood best friends to lovers to strangers to lovers, and more! some of my fav tropes in one book <3 i love the parallel events between the past and present chapters, seeing how percy and sam grown and matured but also stay the same throughout the years (iykyk - the friendship bracelets, “swear on it”, ice cream). their attraction and connection are undeniable! the book perfectly captures friendship, teenage angst, first love, loss, mistakes, and forgiveness. it’s also about finding your person, someone who understands you like no other. the writing was spectacular - it was so magical and enchanting as it encapsulated summer nostalgia at a lakeside cottage. i felt like i experienced every summer with percy and sam. i love how real and relatable the characters are. percy and sam are two flawed characters that let their fears get in their way, but they try their best to repair what they broke. i adore sam so so much, he’s the sweetest and kindest guy who loves really hard. the sarcasm and banter between the two were soo good too, i loved how we get a glimpse of what they were like at 13 and then at 30. this is the PERFECT summer read, i highly recommend it!! i promise you’ll love this if you love ‘love and other words’ by christina lauren! i didn’t think i’d find a book like laow that hits the same, but reading this book made my lil laow heart so happy 💞 i’m blown away by the fact that this is carley fortune’s debut novel and i hope there is more to come!

A book that hugs back.
Format: Hardcover, Format: Hardcover
I picked this book for my brother-in-law when we were celebrating my sister’s pregnancy, and the title ‘Why a daughter needs a dad’ sealed the deal. The illustrations are beautiful and full of tenderness. The messages on each page are simple and meaningful. I could so clearly picture him reading it to his baby girl someday. It’s the kind of book that isn’t just read – it’s felt. A thoughtful gift for someone you love – especially during such a special season of life.
