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

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Surface modification: The introduction of chlorine atoms into chlorinated quantum dots alters their surface properties and enhances their ability to interact with other molecules.

Optical performance: Chlorination may alter the optical properties of quantum dots, such as fluorescence emission wavelength, fluorescence quantum yield, etc., to meet specific application requirements.

Catalytic performance: In some cases, chlorinated quantum dots exhibit excellent catalytic performance, which can accelerate the progress of chemical reactions.

Stability: Chlorination treatment may improve the chemical and environmental stability of quantum dots, enabling them to maintain stable performance in complex environments.


Application Fields

 

 

 

 

 

Optoelectronic devices: Chlorinated quantum dots can be used as luminescent materials in optoelectronic devices such as LEDs and displays, improving the luminescence performance and stability of the devices.

Catalytic field: Utilizing its excellent catalytic performance, chlorinated quantum dots can be used for catalytic degradation of organic pollutants, photocatalytic hydrogen production, and other fields.

Biomedical: In the field of biomedical science, chlorinated quantum dots can be used for biological imaging, drug delivery, etc., providing new means for the diagnosis and treatment of diseases.

Sensors: The high sensitivity and rapid reaction ability of chlorinated quantum dots make them suitable for making various sensors for detecting harmful substances or biomolecules in the environment.

Great Protection w/out the White Cast
Style: SPF 50, Size: 3 Fl Oz (Pack of 1)
We had been using the ThinkBaby mineral sunscreen for years. I wanted to look for a similar alternative but with less white cast. I actually bought this on a whim because it had the fastest shipping at the time (needed it for an outdoor event we were going to). We are now three purchases deep with this product. In my opinion, I think it gives the same amount of sun protection as before without the white cast. It rubs in great. Non-greasy. Initially, the lack of added fragrance was a little off-putting because we were so used to the typical coconut or citrus scents, but we all got used to it. Definitely on my list of subscription purchases now. I wish it was available in a larger size.

Smells good, covers well, it does leave a white sheen, I don’t need to reapply.
Style: SPF 50, Size: 3 Fl Oz (Pack of 1)
I use this just once on my face in the morning, apply makeup over it, and I haven’t burned yet! Been using it for two years now. Unfortunate thing is that my face is not tan at all because it doesn’t allow any rays. LOL So I my makeup has to match the rest of my body… I stay under an umbrella at the beach for about half of the time that I’m there. Otherwise I am out in the sun. And I do not reapply this. I am in the sun between the hours of 9 and 1 PM and I’m in and out of the shade and sun half of the time. Still no burning. Actually I don’t think I reapplied it at all once I got home from the beach and I was out at the pool regularly for another hour with no shade. So it seems to be pretty darn good! Some people say they don’t like the smell, but I specifically bought it because I love love love the coconut smell. My daughter says it smells like bananas but I don’t like the smell of bananas and I don’t think it smells like that. It does definitely leave a white sheen. Hence my need for make up.

Great for Hawaii!
Style: SPF 50, Size: 3 Fl Oz (Pack of 1)
I spent hours trying to find a sunscreen that was “reef safe” since I was going to be spending a lot of time near corals and this was the best one I found. It doesn’t have any of the 3 ‘O’ ingredients that are known to damage reefs. And the zinc is non nano as well. Sunscreen goes on easily. One of the better mineral sunscreens I’ve tried, this one actually smooths out like lotion and feels hydrating. Only leaves a slight pinkish hue, but that is inevitable with mineral sunscreens (that’s literally how they work in reflecting the sun). I could feel it on even in the ocean so I get protected, but still reapplied almost every 2 hours. No burns! I didn’t use it on my face but my partner did and it never stung his eyes nor caused any breakouts!

Stick format is thick and difficult to rub in moderate climates
Style: SPF 50, Size: 1 count (Pack of 1)
I wanted to like it because the small stick format seemed very convenient to keep in my bag for emergency sunscreen reapplication with no chance of leaks. But I think I have learned my lesson about stick sunscreen - in order to hold together in a stick, it has to have a thick and chalky consistency. Which makes it hard to apply and hard to rub in. It's so thick that if I rub the stick over my entire face it feels like I'm applying way too much with a super heavy white cast, and if I dab here and there and try to spread it around, it's so thick it doesn't feel like it spreads into good coverage. The scent is fine. Update: I have found a specific use case for this - in extreme UV conditions like the equatorial tropics in midsummer, it's a good base layer under a more liquid mineral sunscreen, to add extra protection to the most exposed skin, like tops of shoulders, chest, nose and top of forehead. The thickness makes it protect better. It also softens a little and rubs in better in hot temps.

Needs to be warmed, but works great for quick face re-application
Style: SPF 50, Size: 1 count (Pack of 1)
I love mineral sunscreen, it really works the best. But I also do not love mineral sunscreen because it's hard to apply. I don't think it matters what you do, they're just always difficult to apply and always leaving the white. This one isn't much different. I'm a scuba diver and my face sunscreen is washed off quickly doing multiple dives. I also get a weird "mask sunburn" if I don't reapply... but since I'm a diver I can't bring myself to buy or wear sunscreen that's not reef safe into the ocean. I was unsure if this would work because it's pretty solid. I threw it in my bag and once the sun warmed it up a little, I was able to apply it fairly easily between dives. I don't think it works unless it's warmed a bit first, but I like it for this purpose.
