New ceramics welding technology does not require heating parts in a furnace

0 Comments

Engineers used an ultra-fast, low-power pulsed laser to melt ceramic parts along the joint and their welding in ambient conditions. Ceramic materials are of great interest because they are biocompatible, hard and durable. However, current methods for welding ceramics are complex and require high temperatures that can cause cracking. It also prevents electronic components from being […]

Scientists have achieved superconductivity at room temperature for the first time

0 Comments

Researchers finally find a way to create a resistance-free flow of electricity at room temperature. The creation of superconductors without electrical resistance and magnetic field is «the holy grail» physics, because it will open the way to technologies that can radically change our world. Until now, such properties have been observed only in some materials […]
