One reason is that the chemical bond between each carbon atom that makes up a diamond is extremely strong. Another is that the atoms form a rigid structure—each atom is connected to four others ...

This method, particularly when combined with chemical vapor deposition (CVD) techniques, allows for the controlled growth of diamond films and structures on various substrates. Recent research has ...

Although the team probed carbon structures at unprecedented pressures of around 2,000 gigapascals (about 5 times the pressure found at Earth’s core), the crystal structure remained in a diamond ...
