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.

I want to live in these
Color: 01-multicolour (4-pack), Size: Medium
I bought 4 different sets of new underwear. Unfortunately these came last. It’s unfortunate, because if they had come first I would have cancelled all my other orders or returned them and ordered more of these. I never want to wear anything else ever again; these are the comfiest undies I’ve ever owned, I want to live in them. I can wear them under pretty much anything except leggings or very tight pants (but let’s be honest, I don’t wear those anyway.) They are incredibly soft and breathable, they wash well, don’t roll, keep my thighs from rubbing, are comfy to sleep in, and the colors were true to the photo. Just a heads up, they are on the thin side and just a bit see through in the rear. I’m 5’5” 140lbs and the mediums fit perfectly, they go about mid-thigh.

Extremely comfortable
Color: 02-multicolour (4-pack), Size: X-Large
These are by far the softest and most comfortable underwear I have ever owned. The leg portion absolutely does roll up as so many others have mentioned, however, I did not find that to be uncomfortable at all just annoying that they don’t stay in place. I bought these specific underwear to see if it would help alleviate HS symptoms at all. They have definitely helped with wicking moisture away from the skin. More time will tell if it’s truly helpful for HS. For now, I will recommend these. They are thin, breathable, butter soft, wick moisture comfortable and I would buy again…maybe in a different style next time. I have washed them several times and they seem to be holding up rather well so that is also of supreme importance given the cost of the item. Again, I would recommend this item and plan on purchasing more in a different style very soon.

Eaten by my Thighs
Color: 04-multicolour (4-pack), Size: X-Large
I wanted to love them. Sadly they have let me down. Pros: natural breathable fabric , super soft and comfortable, cotton panty gussets for feminine health and panty liners will stick!! Yay:). And the colors! They are great! But here’s the Con. And it’s the con of all cons. THEY RIDE UP!! Eaten by my thighs. I’m 5’6” and in the general area of 175. I fluctuate depending on how many times I visit the bakery! :) I don’t have a thigh gap but it is not a super tight thigh squeeze. I seldom have thigh climb but these do. I tried two different sizes to see if that made a difference. Nope. I was miserable at a recent theme park in these. I was wearing long heavy dresses and it was quite awkward to yank these legs down non stop. They feel amazing and they have all the requirements 1. Soft 2. Comfortable and stretches with you 3. Breathable with nice thin fabric. Not bulky 4. Natural fibers 5. Great colors If you are a person that is not blessed with Thunder Thighs, please order these. They are great! I wear them at home and to locations that I will not be doing a lot of walking at. I have washed them so many times and they look like new still.

Best Boxer Briefs for Women!
Color: 09-multicolour (4-pack), Size: Large
I rarely give 5⭐️’s but these deserve it! Hands down, the most comfortable material, stitching, waistband, moisture wicking and overall comfort. They sit right beneath my bellybutton, they wash and dry well and they’re sturdy. I have tried 3 styles and these are the best.

Comfortable and cool. Does not ride up.
Color: 01-multicolour (4-pack), Size: Medium
Extremely comfortable. Stays cool. Ample coverage. Quality material. They do not creep up. I ordered a medium which I generally take a size small. I have reordered and will reorder again to add more colors to my collection.
