Product Overview

Silicon dioxide (SiO2) is one of the most abundant, structurally complex, and widely used inorganic materials on Earth. It has many forms, such as quartz crystal, amorphous silicon dioxide solid, silicon dioxide colloid and different kinds of aerogels. Generally, the silicon atoms in silicon dioxide molecules are tetrahedral coordinated, consisting of four oxygen atoms surrounding a central Si atom. In recent years, silica particles have shown significant value in the fields of materials chemistry and physics due to their adjustable size, morphology, microstructure, and easy surface functionalization. Particularly, silica particles functionalized with various functional groups have been widely used in catalysis, adsorption, sensing, and biomedical applications. The synthesis methods of silica particles include: sol gel method, lotion method, precipitation method and chemical vapor deposition method, among which the sol gel method is often used in the laboratory due to the high quality of silica particles. In the sol gel method, tetraethyl silicate (TEOS), tetramethyl silicate (TMOS) and polysiloxane are usually selected as the silicon source, ammonia is used as the catalyst, and is dispersed into a suitable solvent (alcohol or water) to form a solution. By controlling the pH value, the silicon source is hydrolyzed to obtain a sol system, and then aged to gel. Finally, the solvent is evaporated by heat treatment to obtain monodisperse silica nanoparticles, which is also referred to as the Stober method.

Application Fields

 

1. Controllable particle size: By adjusting reaction conditions such as reactant concentration, reaction time, temperature, etc., the size of silica particles can be accurately controlled.

2. Good monodispersity: The prepared solid silica particles have good monodispersity, that is, the particle size distribution is relatively uniform.

3. Adjustable surface properties: Its surface chemical properties can be changed through subsequent surface modifications to meet different application requirements. Such as amination (APTES modification) and carboxylation (succinic anhydride modification).


Product Features

 

1. Chromatographic packing: Due to its good monodispersity and chemical stability, it can be used as a stationary phase packing in high-performance liquid chromatography (HPLC) and gas chromatography (GC).

2. Optical materials: used for preparing optical coatings, anti reflective films, etc., to improve the performance of optical devices.

3. Coatings and Coatings: Enhance the wear resistance, corrosion resistance, and hardness of coatings and coatings.

4. Biomedical field: Surface modification of specific antibodies or ligands for the isolation of specific types of cells. It can also be combined with fluorescent dyes or quantum dots for imaging of cells and tissues.

The best car tablet holder
Color: Black
This was our second iPad holder for the car. The first one was sort of flimsy and made a lot of noise. This one is perfect and we can either put it in front of one child or extend the arm and put it between both of them. We’ve actually just left it on the headrest because it feels secure and it doesn’t rattle or make noise. We’ve had it about 7 months and it’s been great. It’s installed through a spring loaded grip and it’s great and fits in my 2019 highlander perfectly.

Perfect For Road Trips
Color: Black
I purchased this car headrest tablet holder for my son to use on our road trips, and it’s been a game changer. The holder is sturdy and easy to install, and it keeps his tablet secure and perfectly positioned for watching videos or playing games. It fits a variety of tablet sizes and stays steady even on bumpy roads, which makes long drives so much more enjoyable for him. I love that it frees up the front seat area and keeps him entertained without having to hold the device. Overall, this is a great travel accessory for families. Durable, adjustable, and simple to use — highly recommend!

LOVE THEM🩷
Size: 10FT, Color: Pink
Love these charges so much and have been using them for years! However, each charger only lasts about 6 months. I think they are worth it though and very good. It comes with two so you only need to buy a new pack once a year. Most chargers nowadays don’t last anyway. These charge fast and are very long. Also love the color options, I have mine in pink🩷

Long Cables and Easy to Spot
Size: 10FT, Color: Blue
So far these have been great chargers. They charge quickly and we have not had any issues with them overheating or causing problems with our iPhones, which is always my main concern with third party chargers. The 10 foot length is a big plus. It gives plenty of flexibility whether you are on the couch, in bed, or working at a desk. The extra length makes a noticeable difference compared to standard cables. I actually bought the blue set for my wife so her chargers would stand out from all the white ones around the house. That has worked perfectly. They are easy to identify and no one else grabs them by mistake. The two pack was ideal for that reason, giving her one for the bedroom and one for another room. If you are looking for a fast charging option with longer cables and want something that is easy to distinguish from the usual white cords, this is a solid choice.

Great block & cables!
Size: 10FT, Color: White
Chargers work fantastically! Charges iPhone 16 superfast as well as new larger iPads. I’ve also used it to charge my MacBook Pro, which it works well with that as well. Doesn’t seem to get excessively hot and the cables are of high-quality. Have bought a lot of these so far and love them!
