They found a way to suppress the effect of coffee rings in Tyumen 03:24

Konstantin Kolegov, researcher at the Center for Nature-Inspired Engineering at Tyumen State University, said: RIA NewsHe said the university had found a way to suppress the effect of coffee rings (ECR).

The essence of the effect is that during the process of drying a drop of liquid solution, an annular precipitate appears, which is associated with the movement of suspended matter in the solution to the edges of the drop as the liquid itself evaporates.

It is reported that eliminating ECC can improve the accuracy and overall efficiency of evaporative lithography techniques used to create biosensors, electrically conductive coatings, and photonic crystals.

“This is in demand in various fields, for example, when creating metamaterials for optics and microelectronics or obtaining functional coatings in nanotechnology,” Kolegov said.

Before that scientists developed Memory in aging mice using coffee.

Russian scientists before was created Vodka-powered space engines.
