Aerogel is the lightest solid material ever discovered. This cool gel is actually the lightest solid in the world. Since the invention of the gel by American scientist Samuel Kistler, the gel has been used in a variety of fields. Aerogels are used in the aerospace industry to collect dust from the tail of a comet, government agencies use to make waterproof and insulated tents, and also to produce heat insulated clothing that is used to protect people from excessive heat. NASA uses the Blue Smoke nickname for the substance.
The interesting thing about this material is that there are several contradictory properties at the same time. This hard gel is more of a mass than a sponge, so it is very lightweight like a sponge, albeit very different from sponge. At the same time, this material is very good for repelling heat and resisting the passage of heat.
The unique molecules of this material can act like a baseball glove! These molecules can absorb fine particles that move at high speed without damaging their structure.
Scientists used silica-based airgel on a pickup device that resembled a large tennis racket in Stardust operation. Its task was to collect tiny particles of comet wild comet 2 without damaging the particle structure. Because the gel is relatively transparent, scientists can identify and extract the particles after they are collected.
The similar substance that existed before the airgel is actually edible jelly. The gelatinous substance in the jelly mixture will form a soft liquid solution if the jelly powder is mixed with warm water. The solution is then cooled and, after cooling, it becomes an elastic material with an irregular molecular lattice, which wraps this new chemical, such as the fibers of a coarse coil. If you reheat the jelly at the end, the existing jelly will again become the original powder.
Of course, airgel is not made of gelatin, but it can be made from various minerals such as silica, depending on the type of use. Siles is the most abundant material in the Earth’s crust. Unlike jelly making, the airgel is made in a pressure-cooling and heating cycle, which allows it to maintain its original shape after drying.
