ultrahakupaineet
Ultrahakupaineet, known in English as ultra-high pressures, refer to pressures exceeding 10 gigapascals (GPa). This extreme pressure range is significantly higher than those typically encountered in everyday life or even in industrial processes. Achieving and maintaining these pressures requires specialized equipment and techniques. Diamond anvil cells are a common laboratory apparatus used to generate ultra-high pressures, by squeezing small samples between the tips of two opposing diamonds. Synchrotrons are also crucial facilities for studying materials under such conditions, as they can provide intense X-ray beams necessary to probe the structural changes occurring at these extreme pressures.
The study of materials under ultra-high pressures is a field of significant scientific interest. At these immense
