<p>➀ Scientists at the Chinese Academy of Sciences' Institute of Physics have developed a new method called vdW squeezing to produce 2D metals at the angstrom thickness limit; </p><p>➁ The technique involves melting and compressing metals under high pressure between two rigid van der Waals anvils; </p><p>➂ This method allows for precise control over the thickness of 2D metals at the atomic level, enabling the exploration of unique layer-dependent characteristics.</p>
