The material works by introducing sulfur atoms into the structure of multi walled carbon nanotubes, a method that can introduce new chemically reactive active sites into the lattice of carbon nanotubes, thereby altering their physical, chemical and electrical properties.

Product Name

Name:Sulfur-doped multiwalled carbon nanotubes


Product Overview 

Sulfur-doped multi-walled carbon nanotubes (S-MWCNTs) are chemically modified carbon nanotube materials. The material works by introducing sulfur atoms into the structure of multi-walled carbon nanotubes, a method that can introduce new chemically reactive active sites into the lattice of carbon nanotubes, thereby altering their physical, chemical and electrical properties. Sulfur doping changes the conductivity of carbon nanotubes, increases the electron transport rate, and then increases the embedding/deembedding rate of lithium ions, and improves the charge-discharge performance of the battery. Sulfur doping provides additional receptors and donor sites, enhances the interaction between carbon nanotubes and reactants, and increases the catalytic reaction rate. Sulfur doped carbon materials have the characteristics of high capacity, low sodium embedding platform, easy regulation and good stability, which can improve the microstructure and electronic structure of carbon materials, and is an effective way to improve the performance of sodium storage.


Technical Parameter

 

Purity:>98wt%(EDS:/span>

Diameter:10-30nm(TEM:/span>

Length:2-20μm(SEM:/span>

Appearance:Black powder

Product Features

 

Enhanced catalytic activity: Sulfur doping can introduce active sites on the surface of multi-walled carbon nanotubes, thereby improving their catalytic activity.

Regulation of optical properties: Sulfur doping can change the optical absorption and emission characteristics of multi-walled carbon nanotubes.

Improved biocompatibility: Compared with undoped multi-walled carbon nanotubes, sulfur doping can improve their biocompatibility.

Enhanced gas adsorption capacity: sulfur doping can increase the adsorption capacity of multi-walled carbon nanotubes for certain gases, such as carbon dioxide, hydrogen sulfide, etc.

 

Application Fields

 

Energy field: As a battery material, supercapacitor electrode material, etc., to improve energy storage and conversion efficiency.

Catalytic field: as a catalyst carrier or catalyst itself, improve the activity and selectivity of catalytic reactions.

Biomedical field: Used in drug delivery systems, biosensors, etc., to improve drug delivery efficiency and biodetection sensitivity.

Environmental protection: Used in gas adsorption and separation technology to help solve problems such as air pollution and water pollution.

Tons of info!
Format: Paperback
If one wanted to be a real tracker, this book has everything needed. I just want to be able to recognize the local wildlife tracks. But having all the rest of the info is nice, and it's easy to take what I want. The book is well organized. Fantastic pictures, loads of information. It's interesting too, to see just how much knowledge goes into figuring out not only what animal it is, but what sex, age, gait, etc it is. This is an awesome book.

Caveats for the professional tracker
Format: Paperback, Format: Paperback
This is a most excellent resource, arguably the best single tracking book that exists (i would argue so, if i had to pick one! And i recommend this book often). However, if you are in a professional field where this legally matters (EIS or ESA decisions on wolverine/fisher/lynx, etc.), take heed: the authors’ methods of measuring tracks are confusing (i.e. - where is the line between substrate/mammal family to determine when claws or ‘posterior’ pads are or are not used in measuring tracks? ) Also, the claim that “an individual animal can show incredible variation in track size” (p.57) is very misleading… Foot size of an individual animal from birth to adult will obviously change, but will not change in a day for the same-aged individual animal regardless of whether it walks in mud or atop rock. The animal’s foot does not change in size, but its track might appear to. This perceived “change” could be easily avoided by using minimum outline measurements (which are not discussed in this book, but can be found in the work by J. Halfpenny and others). I understand their reasons, but please do not refer to this book for legally defensible measuring techniques of rare species!!!! Also please disregard the negative reviewer who said “it’s a very Mythological Approach to how animals move and walk (jsopel),”- they clearly don’t know what that word means… All in all a well-researched and fantastic book that comes from ample and legitimate experience. A great book and happy tracking!

A must have for wildlife lovers
Format: Paperback
Wow! What an excellent and thorough compilation of scat and tracks. Nice reference for when you take pics and bring the image back to the book for comparison. Also, great information about tracking.

Good but index needs improvement
Format: Paperback
This is a good, comprehensive guide to tracks and sign. However, there is no index of where to find each family, so in order to find a species you have to flip through the entire book looking for the right page. This makes it annoying to use if you are trying to look up information on a particular species or family.

This is a very useful field manual for those interested in detailed traking methodology.
Format: Paperback
I spent many years as interpreter and ranger for the Colorado State Park System, now called CPW—Colorado Parks and Wildlife. We were annually tasked with surveying a given species' presence, density, and range in the park system and surrounding areas. Detailed field manuals were critical to the accuracy of our work, and HOW I WISH I HAD THIS BOOK DURING THAT PART OF MY CAREER. There are few other books I've come across providing detailed, yet very accessible information on how trail sign reflects animal behavior across different conditions, landscapes, and seasons (both weather seasons and mating seasons). One particular aspect of this book I found significantly intriguing was the section on predation—how does a mountain lion take down a mule deer vs. how wolves bring one down. The locations on a prey animal where a certain predator is most likely to attack, showing illustrations, is a remarkable piece of work, and there authors are clearly masters of interpreting tracks and sign! If you want learn about how mammals behave in their native environment, adding this book to your field manual packet will greatly expand your horizons! Busy it, read it, and get outside! Thank you Mr. Elbroch and Mr. McFarland for adding to the wildlife canon!
