Inert atmospheres consisting of gases such as argon, nitrogen, or helium are commonly used in chemical reaction chambers and in storage containers for oxygen-or water-sensitive substances, to prevent unwanted reactions of these substances with oxygen or water. [4] Argon is widely used in fluorescence tubes and low energy light bulbs.
Bioactive metallic glass is a subset of bioactive glass, wherein the bulk material is composed of a metal-glass substrate and is coated with bioactive glass in order to make the material bioactive. The reasoning behind the introduction of the metallic base is to create a less brittle, stronger material that will be permanently implanted within ...
Because of that, amorphous materials have a characteristic threshold temperature termed glass transition temperature (T g): below T g amorphous materials are glassy whereas above T g they are molten. The most common applications are in the making of pottery , glass, and some types of food, but there are many others, such as the vitrification of ...
Tap water is not sterile and may contain waterborne germs, such as bacteria, fungi and amebas, which form a biofilm barrier to water treatment chemicals — mainly chlorine and chloramine ...
Unless stated otherwise, the properties of fused silica (quartz glass) and germania glass are derived from the SciGlass glass database by forming the arithmetic mean of all the experimental values from different authors (in general more than 10 independent sources for quartz glass and T g of germanium oxide glass). The list is not exhaustive.
Materials that allow the transmission of light waves through them are called optically transparent. Chemically pure (undoped) window glass and clean river or spring water are prime examples of this. Materials that do not allow the transmission of any light wave frequencies are called opaque. Such substances may have a chemical composition which ...
Oscar Wong/getty images. 5 Things That Might Happen if You Drink a Gallon of Water a Day 1. You’ll Have to Pee All the Time. This one isn't too shocking: Drinking more water will mean more ...
A) A water droplet on a superhydrophilic surface has a very low water contact angle since water will spread out on the surface. B) Dirt or debris (blue circle) on a super hydrophilic surface can be lifted off of the surface as water spreads beneath it. When water slides off of the surface, the debris is removed with the water.
