Silica microspheres are inherently hydrophillic and negatively charged. These particles provide higher opacity than glass microspheres and are often used as contrast particles. Aqueous suspensions of silica microspheres rarely require the use of surfactants or stabilizers. Silane coatings enable silica microspheres to be modified to generate functional groups or alter surface properties. Additional advantage of silica microspheres is glass transition temperature of over 1000 degrees Celsius, which makes them suitable for high temperature applications. Silica microspheres and nanospheres are composed of synthetic amorphous silica made in a laboratory batch environment.

Lists combine the ease of Bookmarks with the versatility of Tags. Instead of one collection of bookmarked items, create as many collections, called "Lists," as you need.
Previous Bookmarks and Tags
Find the link to your List page in the user menu.
All Tags have been converted to separate Lists, and your bookmarked items have been saved to a "Bookmarks" List.
Adding Items
When you click the Add to List button, a dropdown of your existing Lists appears. Click the List name to which you want to add this product or formula.
Create a New List
You can also create a new List. Simply click "Create a New List" and enter a name.
Multiple Lists
When you define a new List, the current item is automatically added to it. You can add a product or formula to as many Lists as you need.
Explore Your Lists
Easily see which Lists this item appears in, and quickly go to that List from the links that appear on the page.
