Decoding 2D materials growth: Insights in white graphene open door to cleaner energy and more efficient electronics
a) The diffusion route of borazine on Ru(0001) shows that borazine moves by alternating rotational movements between HCP and FCC sites as it diffuses across the surface. Regarding hydrogen removal from borazine, b) shows that B-dehydrogenation is the kinetically favored product, while N-dehydrogenation is thermodynamically favored. Credit: Small (2025). DOI: 10.1002/smll.202405404 A breakthrough in deciphering the growth process of the…

New manufacturing strategy improves graphene airgel sensitivity and durability for human-machine interfaces
Graphene airgel shows potential as a high-performance pressure sensor in human-machine interfaces due to its mechanical properties and electrical conductivity. Anisotropic chitosan graphene oxide (CS-GO) airgel metamaterials with highly ordered honeycomb microstructures were synthesized using conventional directional freeze casting. Subsequently, cross-linked chitosan and reduced graphene oxide (CCS-rGO) aerogels with buckled networks achieved by heating and post-crosslinking at 180 °C for…
