Researchers visualized how gold nanocrystals coalesce at the atomic level, uncovering size, defect, and approach-dependent pathways that shape crystal structure.

The topics include the fundamental problems of phase transitions, nonlinear and collective phenomena during crystal growth, physics, chemistry, mechanics of crystal surfaces, lattice defects. The ...

Crystallization, a fundamental process in nature, hinges on two distinct stages: nucleation and growth. The latter plays a pivotal role in shaping the morphology, size, and purity of crystalline ...

Background Previous theoretical models of nanocrystal growth typically involve classical two-step or multi-stage mechanisms, including nucleation, monomer addition, and particle fusion. These models ...

Summary It was possible to observe the repeated nucleation and growth of NaCl nanocrystals in a single conical CNT as part of a single continuous in-situ video acquisition. This was recently published ...

Although non-classical nucleation theories may be a more sustainable model, the atomistic mechanisms and structural evolutions during nucleus formation in non-classical nucleation pathways are not ...

Simplified Diagram of Nanowire Growth Using the Vapor-Liquid-Solid (VLS) Method: This illustration shows how nanowires are synthesized using a gold-silicon (Au-Si) catalyst on a silicon substrate. The ...

Replicating key processes—including carbon diffusion, chain formation, and graphene nucleation—the study revealed that carbon growth on Cu (111) surfaces follows a specific sequence, with ...
