Mesoporous Solid-core Silica Nanoparticles:00-120 nm)


Product Overview

Mesoporous materials (pore size 2-50nm) have a pore size between microporous materials (pore size<2 nm) and macroporous materials (pore size>50 nm), and possess many excellent characteristics, such as highly ordered pore structure, single pore size distribution, and high stability, making them a hot research topic in recent years. As a common inorganic nanoparticle, silica nanoparticles have a series of advantages such as controllable morphology, ordered and adjustable pore structure, large specific surface area, easy modification of surface functional groups, and good biocompatibility, which make them widely used in biomedical, catalytic, environmental, optical and other fields. The main preparation method of silica nanoparticles is the sol gel method. Under the catalysis, the silicon source is formed by hydrolysis and condensation. This method was first proposed by Stober in 1968. According to the morphological characteristics of silica nanoparticles, they can be roughly divided into three types: solid silica, mesoporous silica, and hollow structured silica. Among them, the pore structure of mesoporous silica is generally formed by template method, which includes soft templates and hard templates. Soft templates are generally amphiphilic surfactants, while hard templates are generally high molecular weight polymers, with soft templates being more commonly used. The preparation process of mesoporous silicon can be divided into two stages: firstly, the template interacts with the inorganic precursor to synthesize liquid crystal structural phases with nanoscale lattice constants of organic and inorganic materials under certain conditions; Then, high-temperature heat treatment or other physical and chemical methods are used to remove the template, and the space left by the template forms mesoporous channels. The surface of silica nanoparticles has abundant silicon hydroxyl groups, which facilitate their surface chemical modification. By modifying different functional groups, silica nanoparticles can be endowed with more functions. The commonly used types of surface modifications currently include surface amination, thiolation, and organic chain functionalization. The surface modification of silica nanoparticles is mainly achieved by introducing different types of silane coupling agents, such as 3-aminopropyltriethoxysilane (APTES), which can be used for amination modification, and 3-mercaptopropyltrimethoxysilane, which can be used for thiol modification.

(Note: The specific surface area is the data of a single test, allowing floating between different batches. For reference only, whichever is in kind.)


Product Features

1) Multiple active sites: Due to its large specific surface area and abundant surface active sites, amination solid mesoporous silica nanoparticles can be used as catalyst carriers to improve the activity and selectivity of catalytic reactions.

2) Large specific surface area: due to the existence of mesoporous structure, it has a large specific surface area, which is conducive to adsorption and loading of drugs or other molecules.

3) Good hydrophilicity and biocompatibility: Amination improves the hydrophilicity and biocompatibility of nanoparticles, which contributes to their application in vivo.


Application Fields

1) Biomedicine: In the field of drug delivery, aminoated mesoporous silica nanoparticles can be used as drug carriers to achieve targeted drug delivery and controlled release;

2) Catalytic carrier: as a catalyst carrier, its high specific surface area and ordered pore structure are conducive to catalyst dispersion and mass transfer of reactants;

3) Adsorption separation: After surface amination, the surface of the nanoparticles has a positive charge, which helps to adsorb negatively charged substances, such as some pollutants and biomolecules;

I like the nylon strap.
Color: Black/White/Black
Watch itself is fine - doesn't stand out as something spectacular but is great for what it is. Definitely waterproof to about 30 feet deep - I've tested it snorkeling. The best thing is the strap - this nylon strap is much more comfortable than usual watch straps. There are a lot of nylon straps out there -- I think I prefer this one more than most of the others. the Velcro allows infinite adjustment, unlike straps with holes like a belt. And the way they did the looping of the band around itself seems to work really well. Better than another velcro strap I had many years ago ("the band") which was similar but didn't loop around itself the same way. This one is better - quicker and easier to put on and more easily adjustable.

Great purchase
Color: Black/White/Black, Color: Black/White/Black
The perfect watch for my eyes. White background with black hour and the second hand. Standard stuff… It’s all about the simple things that matter to me. The indigo green light might not appeal to everyone (look at the price). The band is fabric with Velcro to adjust. I’ve work this watch day and night. A near perfect fit. Easy to adjust and it’s comfortable for me, the look is just right for me. A no brainer to set up immediately. Time (?) will tell about minute creep or over all durability, A nice affordable watch that I I’ll wear everyday under all conditions. If I loose it I’ll buy another one.

Inexpensive Box Checker That Works Great!
Color: Black/White/Black
Although I have a few watches I was looking for something that was more camping specific. Something that was EASILY legible to my 56 year old vision - both in daytime and night. I needed it to have some waterproofness ability as I would also using it for kayaking. I had a Timex Expedition watch with a black dial that I gave to my son as I wanted one with a white face which I find easier to read. I gave this watch some serious consideration after seeing so many YTbers give Timex field watches the thumbs up. I came upon this model and then when I saw one available under $30 it became a no-brainer! I used it recently for its intended purpose - a 3 day camping weekend. So here are my observations. The strap is probably the only negative to the watch for me as I have big hands and need to undo it completely to feed the strap through the buckle. A minor hindrance. Once its on it's light and comfortable. I may eventually change out the strap...or I may not. The watch is easily legible and nothing, I MEAN NOTHING, beats Timex's "Indiglo" feature for nighttime. Forget "watch lume" as nothing is a visibly legible at nights as "Indiglo". I have a Casio watch that has a light feature but that cannot hold a candle to this watch's nighttime ability. On a kayak trip, I overturned the kayak and the watch was in the water so it held up nicely for that. The watch is rated for 100M so that was nothing for it I know. It's hard to find a watch that does so much at this price point. I would definitely recommend it for someone looking for the features that it has in an inexpensive package.

Decent watch, bad warranty.
Color: Black/White/Black
Decent watch, good design, solid strap. Bad warranty. I spent a little bit more money to get a better quality product with a name brand warranty, and I feel like it was a waste of money. The backlight stopped working within 6 months. I replaced the battery, but it didn't help. I started the process of a warranty repair with Timex, but then found out they have a $8 fee for in-warranty repair. With the cost of the watch being what it is, I'll just deal with the broken backlight. Next time I'll spend less money on cheap disposable non-brand name watches
