Name:Two-dimensional porous carbon nanosheets

Product Overview

Two dimensional porous carbon nanosheets (PCN) are carbon nanomaterials with a two-dimensional structure and high porosity, and their unique properties have wide applications in sodium ion batteries. Sodium ion battery is a type of secondary battery (rechargeable battery), which mainly relies on the movement of sodium ions between the positive and negative electrodes to achieve the charging and discharging process. Sodium ion batteries include a positive electrode, a negative electrode, an electrolyte, a separator, and a current collector. The structure and performance of the positive and negative electrode materials determine the sodium storage performance of the entire battery. The positive and negative electrodes are separated by a diaphragm to prevent short circuits, the electrolyte serves as a medium for ion circulation, and the current collector plays a role in collecting and transmitting electrons. The positive and negative electrode materials of sodium ion batteries can accommodate more sodium ions, thus possessing high capacity storage capacity and able to withstand a large number of charge and discharge cycles, making them more suitable for long-term use and high-intensity application scenarios.

Product Features

 

 

 

 

 

 

 

 

 

 

 

 

Two dimensional structure: unfolded on a plane to form a sheet-like structure.

Porosity: It has micropores, mesopores, and even macropores, with a rich pore structure.

Multiple active sites: Due to the porous and sheet-like structure, a large surface area is provided, which is conducive to chemical reactions and substance adsorption.

Good conductivity: Good conductivity can promote electron transfer and enhance the overall performance of the battery.


Application Fields

 

Supercapacitors: As electrode materials, they provide high specific surface area and abundant ion transport channels, improving capacitance performance.

Battery: As a sulfur positive electrode carrier in lithium sulfur batteries, it reduces shuttle effect and improves battery performance.

Catalysis field: As a catalyst carrier or catalyst itself, it provides a large number of active sites to promote chemical reactions.

Environmental field: Used as a catalyst in advanced oxidation processes to effectively degrade pollutants.

Biomedical field: as a drug carrier or biosensor component, utilizing its high surface area and pore structure to achieve controlled drug release and detection of biomolecules.

Great durable dog toy!!
Size: Large Triple
We have a medium-sized dog (45 lb mixed Aussie/Hound) who is a pretty aggressive chewer. He also loves playing tug-of-war with his canine and human siblings using these rings. This is easily his favorite toy. We bought one a little over a year ago that he plays with daily. If finally broke this December just in time to buy a replacement for Christmas! The prior one finally broke when the middle ring came apart at one of the thinner rubber points. He still plays with the intact outer rings as well as his new toy. I wanted to dock this 1/2 star for a few reasons: 1) it is not completely invincible, although I would argue a toy that lasts over a year with pretty constant play for an $11 price tag is a great value. 2) the one we received is not yellow/black. It is blue/green. I was personally thrilled it was blue/green because it ended up being an exact replacement of the one we had previously. However the description does not say "colors vary" and it was hard for me to tell when ordering if I was ordering the correct replacement toy. A clearer description would be appreciated. 3) This is a great toy for one dog, but our other dobbie/cattle dog mix has no interest in them. So not all dogs will love this toy (obviously). 4.5 stars isn't an option so I'm giving this 5 stars because it's just about as close to a perfect dog toy as one can buy (at least for our dog).

Great toy, as long as dog is NOT ALLOWED to chew on it
Size: Large Triple
Let me start by saying that I like this dog toy. My big dog LOVES tugging with it. As long as you keep away when the dog is in a chewing mood, it lasts a long time (my 1st one lasted a year), however, it WILL NOT last if the dog chews on it, as I found out with this one. A friends dog chewed on it while she was behind a snow mound (mostly out of our sight) when it was only a week old. One end ring was barely holding together when we discovered her chewing it. Fortunately it was an end ring, so I still have 2 connected rings for tugging with. It is a great tug toy! But it is also a TERRIBLE chew toy, so make sure to take it away when your dog starts to chew on it and it will give you long service.

Fabulous toy!!
Size: Large Triple
My GSD is always up for a good game of tug-o-war. I purchased these in large and I think I love them as much as my dog. They are super strong and hold up to his 100lb self pulling on one end and my “blah blah-lb” self pulling on the other. (Ha! You thought I would say how much I weigh) I even bought another pair for our cabin so we have some to play with at both places. He isn't a sit and chew on things kind of dog. He gets plenty of playtime and bully sticks for chewing. Not to mention that I wouldn't let him use them as a chew toy anyway. There are toys for play and toys for chew. Therefore, I cant say anything on how they hold up for chewers. So if you let your dog just sit and chew on it instead of giving them something designed for strong chewers, then no it might not hold up to that. All I can say is my German Shepherd is 100lbs with sharp teeth and stronger than me now and honestly he is probably stronger than I have ever been in my life, and they hold up to the pulling and tugging of both of us. Thats what they're designed for and they serve their purpose excellently.

Won't purchase this one again.
Size: Large Triple
J.W. used to make a ring toy such as this, that was softer & thicker with a smaller black ring in the middle, that our dogs all, absolutely loved!!!!! But this one totally bores them to the point none of the dogs will pay it any attention! Please bring back the original 3 ring toy, that J.W. has now changed to just the one ring! I feel like they must have discontinued the toy with the 3 rings they used to sell, with the smaller black ring in the middle? I won't waist my $ on another one of these! Sadly, none of our 3 dogs will play with this specific toy at all! & I generally prefer to purchase J.W. brand toys for our dogs. But this toy doesn't attract them in anyway. It just sits around.

Great idea but didn't hold up!
Size: Large
My dog and I really enjoyed this as a tug toy to use where it kept my hands away from accidental nips. When we initially got it we let her play solo with it after our tug session and I noticed that she left little teeth puncture holes so we packed it away for awhile and exclusively used the other new toy we bought for her. After a few weeks we took this back out and, again, we loved it and this time I allowed her to play with it longer and although it was showing a lot of the little tooth marks it seemed to be holding up so I left it out with her. None seemed deep, just seemed like impressions from her teeth. We continued to enjoy it for about a week where she'd carry it over to us for tug sessions, loop it on our feet when we were sitting watching tv and chewing on it a bit. I'd look at it when we'd tug and, like I said above, it seemed to be holding up. After one session of tug when she took it off to chew on and I was watching some tv I checked on her after awhile and she had bitten through the black side and had chewed up into small pieces about a two inch section of it. Small, little hard bits were in a pile on the floor. She didn't just bite through, it had broken into small, little pieces and hopefully I was able to get all of them and she didn't swallow any! So if you want to get this exclusively as just a tug toy and not something for your dog to chew on and plan on putting it away after I think it will be okay for that and should last but if your dog is a serious chewer like ours is you may not want them to be allowed to chew on this. Seemed like it was going to last and then suddenly I was throwing away half of it and hoping she didn't eat any of the black bits. We still have the yellow side and will take that out for some tugging but no longer for her to play with freely!! She did tremendously love running around with this thing and would flip up the loose end and hook it on her face or our feet and was so cute to watch her!! Wish it had lasted!!
