Hydrophilic or hydrophobic? Understanding the keys behind the anti-fog

A common problem It is not an exaggeration to consider fog formation as a worldwide problem that must be solved. The NASA astronauts came across this issue years ago in their firsts space missions but any common person can deal with this problem while driving his car on a rainy day. The physical explanation for this phenomenon is based on the thermodynamics laws and the light-matter interaction. When an amount of water in vapour state contacts with a col

Anti-fog Coatings: Escaping from fog formation

The fog problem The fog formation can be explained by physicists as the condensation that takes place due to the temperature difference between the environment and the surface. You can imagine an analogous situation when clouds that carry water vapour enter a cold area and while they lose some thermal energy, it starts to rain. The formation of little water droplets can be quite annoying if it spoils the transparency of certain surfaces. Who hasn’t seen a

COVID 2019 affected too many lives. Quarantine, an old time pandemic remedy is proven today that it is the most effective temporary solution to prevent virus spread until the discovery of a proven vaccination. One of the colossal impacts was the cancellation of several exhibitions.

Substrates Soda Lime or Borosilicate Glass, Wafers and Crystals

Substrates Soda Lime or Borosilicate Glass, Wafers and Crystals
Soda lime glass or silica sand based standard glass represents 90% of glass offering. To form borosilicate glass we need to add boric acid (B2O3), alumina and soda ash to the silica melt. Low thermal expansion (3,3 × 10−6 K−1 ) is the main property of it. According to the SiO2 content and alkaline earth content there are three groups of B2O3. Technical Glass Substrates, borosilicate glass, Silicon Wafer & Crystals The Non-alkaline-earth B2O3 group or

sputter target: use and manufacturing process

sputter target: use and manufacturing process
sputter target is a physical vapor deposition (PVD) process to form thin films. Thickness of layer formed varies from a few nano-meters up to several microns. Sputtering PVD consist of collisions of ions in vacuum and a plasma environment under strong magnetic field in order to extract atoms from the target and gradually grow a thin film over the desired substrate. Scientific researchers generally use small discs (typical diameters ranges from 0.25 to
