Scientists just found a way to grow diamonds without heat or pressure

University of Tokyo scientists developed a revolutionary method to create diamonds using electron beams instead of extreme heat and pressure, starting with adamantane molecules that mirror diamond's structure. The controlled electron irradiation process transforms these carbon-based samples into near-perfect nanodiamonds up to 10 nanometers wide while protecting delicate organic materials from beam damage. This breakthrough could advance quantum computing, microscopy, and materials science applications.
