Name: Carboxyl Graphene quantum dots

Product Overview

Graphene quantum dots (GQDs) are nanoscale fragments of graphene with unique physical and chemical properties, such as quantum size effects, edge effects, etc. By specific synthesis methods, the size, shape, and luminescent properties of GQDs can be controlled. At present, Xianfeng Nano's available quantum dots are divided into graphene oxide quantum dots, graphene quantum dots, semiconductor quantum dots, etc. Customers can choose according to their experimental needs. The preparation methods of graphene quantum dots on sale are divided into bottom-up and top-down, with different colors of luminescence available, such as green light, blue light, red light, and white light. Meanwhile, graphene quantum dots with different functional groups can be selected, which is also helpful for later modification coupling. In addition, nitrogen doped and boron doped graphene quantum dots can be selected. At present, the applications of graphene quantum dots are mostly focused on fluorescence imaging, nanoadditives, antibacterial, and biotoxicity.

Product Features

Uniform size: The size of hydroxylated graphene quantum dots is usually between 1-10 nanometers, and their distribution is relatively uniform, which provides a basis for their application at the nanoscale.

High dispersibility: Due to the abundant hydroxyl functional groups on the surface, hydroxyl functionalized graphene quantum dots exhibit good dispersibility in aqueous solutions and other solvents.

Rich reactive sites: Hydroxyl functional groups provide abundant reactive sites for hydroxylated graphene quantum dots, making them easy to connect or modify with other molecules or materials through chemical reactions.

Excellent optical properties: Hydroxyfossilized graphene quantum dots have efficient fluorescence properties, high fluorescence intensity, and long fluorescence lifetime, which makes them potentially valuable in fields such as biological imaging.

Good stability: Hydroxyfossilized graphene quantum dots exhibit excellent stability in extreme environments such as high temperature, acidity, and alkalinity.


Application Fields

 

Biomedical science:

Biological imaging: The high fluorescence intensity and long lifetime of hydroxylated graphene quantum dots make them a powerful tool for biological imaging, which can be used for cell imaging, tissue imaging, and more.

Drug delivery: The hydroxyl functional groups on its surface can bind with biomolecules to achieve targeted drug delivery, improve therapeutic efficacy, and reduce side effects.

Biosensing: Hydroxyfossilized graphene quantum dots can be used to monitor the interactions of biomolecules and dynamic processes within cells through mechanisms such as fluorescence resonance energy transfer.

Energy sector:

Solar cells: Hydroxygraphene quantum dots are used as one of the key materials for solar cells due to their excellent electronic transport properties and chemical stability.

Fuel cell: In fuel cells, hydroxylated graphene quantum dots can serve as catalyst carriers or electrode materials to improve the performance and stability of fuel cells.

Lithium ion batteries: Their unique two-dimensional structure and large specific surface area contribute to improving the energy density and cycling stability of lithium-ion batteries.

Environmental Science:

Water treatment: Hydroxyfossilized graphene quantum dots can be used to remove pollutants and heavy metal ions from water, achieving water purification.

Air purification: In the field of air purification, hydroxylated graphene quantum dots have also shown potential application value.

Materials Science:

As a catalyst carrier, hydroxylated graphene quantum dots can serve as carriers for various catalysts, enhancing their activity and stability.

Composite material preparation: By combining with other materials, new materials with special properties can be prepared.

Fantastic
Color: Beige, Size: A-132''W-6 Panel
I am perennially in the process of rearranging, reorganizing, getting ready for yard sales, changing the functions of various rooms, moving everything out of a room to do a deep clean, etc, which means that there is always SOME part of my house, if not the entire thing, that is a disaster zone. Having someone knock on my door triggers a "duck and cover" reflex because it's so embarrassing for anyone to see that I live like this. (I *feel* like I don't, really, because I know that all the various stages are all temporary, but when there's always something temporary going on, it might as well be permanent, you know?) So THANK HEAVENS for a room divider that is not only large enough to divide my uncomfortably long den in half the long way so I can shove all the messy parts up against the back wall -- that is not only simple and attractive and neutral and (this is important) NOT BLACK because I have multiple pets and anything black in this house will be pet-hair-colored within 20 seconds -- that not only has **SIX** panels for lots of options of how I want to divide the space/s -- but is also on WHEELS. Someone out there really does love me, it's true! The panels are stable *enough* - I'm not going to lie and say that nothing is going to knock them over, because I have some balance issues, and I also have cats, and both of those circumstances has resulted in a mess on at least one occasion. But in the cats' defense, they've never dealt with a room partition that didn't hang from the ceiling before; and in my defense, I just grabbed the first thing I could reach on the way down. Not the product's fault in either case. Assembly was a little dicey as I am currently in **bilateral** (oh yes, that's fun) wrist braces, so I had to give up until I had help. But I think if you're able-bodied, you shouldn't have any difficulty. The only down side is, now that I've hidden away all the mess so I can break out the holiday decorations, you know what happens next, right?? That's right... the PERMA-MESS ZONE. Oh no. Oh well.

Difficult assembly, doesn’t fold well, looks good fully open
Color: Grey, Size: B-88''W-4 Panel
The instructions for this divider are very inadequate. After having to redo parts of the assembly, I have finally assembled it. The divider itself seems very nice when it is fully open, however it is not possible to fold it well as all the bars with the wheels go in various directions making it impossible to fold it neatly. And it has a large footprint. It is possible that I did not assemble it fully well because of the lack of adequate instructions. I am not even sure if I will keep it because I need to fold out of the way when nothing in use.

Slightly challenging build
Color: Beige, Size: A-88''W-4 Panel
This was my second screen set I've purchased, first of this style. Not the easiest to assemble. Lots of pulling and tugging; not a highlight in my day.

Commercial grade divider suitable for many needs
Color: Beige, Size: A-132''W-6 Panel
This item will be used at a future event where we need to separate a single locker room into two large areas, without any construction. This divider is perfect for the job because the partitions can be 1 to 6 panels and it will roll into place. When the event is over, the divider will fold/roll away and the locker room will return to its original design. The unit is very heavy, which will ensure that it is sturdy and stable. All the components arrived, wrapped in plastic to prevent damage. The screen material is a woven polyester in a cream color that will occlude any visibility but it may be possible to see shadows on the opposite side. The height is about 6ft, which would require a very tall person to "peep over" the divider. I needed a quality unit for this project and the frame, screens, and mobility will meet the needs. The divider is not the same as the small decorative dividers -- it is more of a commercial grade product, yet tasteful. If you want/need a small divider as an accent piece, this is not the best choice. This item could be used in a medical office, treatment/massage room, to divide an office room into two, or block a hallway in a building.
