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.

Great sturdy chair and beautiful color
Color: White
I love this chair. I bought it for my home office. It is beautiful, sturdy and very comfortable. I'm not good at all with assembling even basic things but I would say that this was relatively pretty simple for someone like me to put together. Good price and good product.

Reliable, Comfortable, and Good-Looking Chair — I Keep Coming Back to It
Color: White
This is my fourth time purchasing this Amazon Basics mid-back office chair, which says a lot about its overall value. It looks clean and modern, fits well in a home office, and is genuinely comfortable for daily use. I typically get about a year and a half out of each one, which feels reasonable given the price point and materials. Out of the box, the chair is easy to assemble and immediately comfortable. The padding is supportive, the armrests are well positioned, and the faux leather gives it a more upscale appearance than many chairs in this category. It rolls smoothly, swivels easily, and works well for long computer sessions without causing back or shoulder fatigue. That said, this is not a lifetime chair. After extended use, the cushioning and structure do begin to wear, and that’s usually when I replace it. Still, considering the comfort, appearance, and cost, it remains one of the best value office chairs I’ve found — which is why I keep buying it again. Pros: • Comfortable padding and good mid-back support • Clean, modern appearance that looks great in an office • Smooth rolling and stable base • Easy assembly • Excellent value for the price Cons: • Durability is moderate; expect replacement after about 1½ years • Not designed for long-term heavy-duty use Verdict: If you want a comfortable, attractive, and affordable office chair that performs well for daily use, this is a strong choice. It may not last forever, but its comfort and value make it easy to recommend — and easy to repurchase.

Good Basic Chair with a Few Drawbacks
Color: Black
I bought this Amazon Basics office task chair for my boyfriend who works from home. Overall, it’s a decent, simple chair that gets the job done for everyday use, especially if you just need something functional and affordable. However, there are a couple of downsides. The recline doesn’t go back as much as he would like, so it’s not ideal if you prefer to lean back and relax between tasks. Also, after about a month of use, the wheels don’t glide as smoothly as they did at first, which can be a bit frustrating when rolling across the floor. Overall, it’s a solid basic chair for light use, but if you want something with a deeper recline or super smooth mobility long-term, you might want to consider other options. Still a reasonable purchase depending on your needs.
