Name: Single Layer WS2 on SiO2/Si


Product Overview

 

The CVD method (chemical vapor deposition) plays an important role in the preparation of disulfide materials, especially for the preparation of two-dimensional layered metal disulfides such as molybdenum disulfide MoS2, tungsten disulfide WS2, etc. When preparing disulfide materials, CVD method utilizes gaseous precursors (such as metal source and sulfur source) to undergo chemical reactions on the heated substrate surface, generating the desired disulfide thin film. According to the type of target disulfide, common metal sources include metal powders, metal halides, etc., while sulfur sources include sulfur powder, hydrogen sulfide, etc.

Two dimensional layered metal dichalcogenides have attracted much attention due to their excellent optoelectronic properties, adjustable bandgap, and excellent air stability. CVD method, as one of the effective methods for preparing such materials, has broad application prospects in fields such as optoelectronic devices, sensors, and energy storage. For example, two-dimensional materials such as molybdenum disulfide and tungsten disulfide have been widely used in fields such as photodetectors, solar cells, and supercapacitors.

WORKS! LIGHT! EASY TO APPLY AND USE!
Took and trip and knew I would be out in the sun. I know this is for the face, but I used on my arms, legs and face. It is light and easy to apply. Not sticky and heavy as some sunblocks can be. I am very pleased with this purchase/find, as it works well and was a fabulous price for this tube.

Lightweight, Smooth, and Truly Unscented — My New Go-To Sunscreen
Size: 6 Fl Oz (Pack of 1), Style: SPF 50
This is the first time I tried this Banana Boat unscented sunscreen, and I’m genuinely impressed. One of the biggest things I look for in sunscreen is how it feels on the skin, and this one delivers—it’s not sticky at all and goes on very smooth. It’s easy to apply and absorbs quickly without leaving that heavy, greasy feeling. I also really appreciate that it’s unscented. There’s no strong or unpleasant smell, which makes it much more comfortable to use daily. I’ve used other brands before, like Neutrogena and some higher-priced options, but honestly, this one stands out. It performs just as well—if not better—at a more reasonable price. Overall, this is a great sunscreen that I’ll definitely keep using. Highly recommended if you want something lightweight, smooth, and fragrance-free.

BEST sunscreen on the market
Size: 6 Fl Oz (Pack of 1), Style: SPF 50
This sunscreen is truly the best sunscreen on the market. I have now bought 4 bottles, and plan to purchase more. It is extremely milky, dissolves onto the skin perfectly, it feels like you arent wearing any sunscreen at all. I tell everyone I know about this product. I also purchase the FACE spf which is even more smooth. I wish they sold this in a giant container, because I apply this everyday !! This sunscreen has made it more accessible for me to apply sunscreen daily, it also has very minimal scent, and never burns your eyes. Personally I will never buy another type of sunscreen again after this sunscreen.

Good for acne prone sensitive skin
Size: 3 Fl Oz (Pack of 1), Style: SPF 50
I am in my 30s with combo leaning oil and acne prone fair skin with pigmentation issues and I’m on prescription tretinoin every day. I sometimes use hydroquinone when my pigmentation issues flare up. I wear sunscreen every single day to protect my skin. It’s especially important since I’m on Tret. daily. Being that I have acne prone skin finding a sunscreen has always been a HUGE challenge for me. I’ve spent so much time on SkinSort and similar sites looking through sunscreen ingredients lists trying to find ones that won’t break me out. I’ve purchased PLENTY of k-beauty, j-beauty, EU sunscreens and Us sunscreens from Sephora and drugstore only for them to break me out. My skin is very sensitive/breakout prone to long ingredients lists, emollients, heavy textures, oils and lots of botanicals. I randomly stumbled upon this banana boat sunscreen here on Amazon and saw the short and fairly simple ingredient list that is low (not free of- but low) in occlusive ingredients in comparison to other sunscreens so I decided to order it. It has not broken me out and it feels nice. No alcohol in it, no irritation, no pimples so far. The tube is user friendly, the texture is light and pleasant and the sunscreen is affordable and accessible. I also appreciate how it’s water resistant so can be worn every day OR pool/beach. I highly recommend this to anyone with acne prone or sensitive skin if you are ok with US chemical sunscreens. I prefer chemical sunscreens over mineral sunscreens as mineral sunscreens break me out. This affordable banana boat in my opinion is WAY better for me personally than high end and expensive options that have tons of pore clogging ingredients. Yes even the popular k-beauty sunscreens break me out unfortunately. Everyone is different and anything has a potential to clog someone but for me this sunscreen is way more safe for my acne prone skin than any other sunscreen option I’ve come across. The majority of sunscreens are just packed with pore cloggers, but this banana boat one is minimal in comparison. The tube is travel size (tsa approved) but bigger than your standard 1.7oz sunscreen. This is nice for me because like I mentioned I wear sunscreen every single day and re-apply if I’ll be outside in the sun. While spending time outside I did not burn while wearing this sunscreen and I’m extremely fair skinned. I also did not notice any new pigmentation issues. The texture is nice, light and pleasant. It wears well under makeup. I normally wash my face in the AM, apply a hydrating kbeauty toner, tiny little dots of super light gel moisturizer (not much- I’m oily!) and then apply this banana boat sunscreen on top. Sometimes I wear makeup sometimes I don’t. It works both ways. I have not experienced any pilling. I have not noticed any scent with this sunscreen other than the sunscreen filters smell which isn’t too bad at all in comparison to other sunscreens I’ve tried. The sunscreen itself adds a touch of moisture but I don’t find it to be greasy on my oily skin. In the summer I will probably use a hydrating toner or serum (skip gel moisturizer) and then apply the banana boat sunscreen since I live in a warm climate. Anyways, this is a very nice textured non offensive not overly clogging (for me at least) Us chemical sunscreen that has been very unproblematic for me. I just apply a decent amount every AM and don’t even think about it. Like I mentioned if I’m out in direct sunlight (normally I’m not in the winter) I’ll reapply as needed. In the PM I use bioderma micellar water and then follow it with my Remedy brand face cleanser and it takes the banana boat off fine. I’m interested in trying the spray version (always spray decent amount into hand and then apply!) for my body in the summer. For now I apply this banana boat sensitive face to my face, neck, hands or whatever exposed area. If you tried the banana boat light as air face spf that one is a little more matte and dry but it’s also more pore clogging in both my experience and by ingredients lists. This banana boat sensitive has a bit of a different texture that’s lightweight and still not greasy but it’s more of a traditional light lotion. The banana boat light as air face one felt great but over time gave me more closed comedones. Needless to say I highly recommend this lightweight Us chemical sunscreen to anyone looking for a simple waterproof Us chemical sunscreen that is affordable and easy. Obviously no white cast as its chemical. Sorry for the long review but it might help someone out. Also I purchased this with my own money I am not a part of one of those product reviewing groups- whatever they are called. No shade to anyone lol.

Great
Size: 3 Fl Oz (Pack of 1), Style: SPF 50
The sunscreen itself is really good. It applies smoothly just as advertised “lotion”. I was pleased to see it didn’t leave a white cast. I apply makeup over my sunscreen often. This sunscreen worked perfectly with makeup. Like it said, it’s unscented and that was true as I didn’t detect a scent. My skin feels nice with this on. My only issue is that it didn’t come with a safety seal under the cap. Usually all products come with a seal to ensure it isn’t tampered with and that buyer gets the full amount of product. That was a bit upsetting but hopefully I didn’t actually get a used one.
