Findings on Crystal Growth Reported by Investigators at Pacific Northwest National Laboratory (A Unified Description of Attachment-Based Crystal Growth)

By a News Reporter-Staff News Editor at Health & Medicine Week -- Investigators publish new report on Crystal Growth. According to news reporting out of Richland, Washington, by NewsRx editors, research stated, "Crystal growth is one of the most fundamental processes in nature. Understanding of crystal growth mechanisms has changed dramatically over the past two decades."

Our news journalists obtained a quote from the research from Pacific Northwest National Laboratory, "One significant advance has been the recognition that growth does not only occur atom by atom, but often proceeds via attachment and fusion of either amorphous or crystalline particles. Results from recent experiments and calculations can be integrated to develop a simple, unified conceptual description of attachment-based crystal growth. This enables us to address three important questions: What are the driving forces for attachment-based growth? For crystalline particles, what enables the particles to achieve crystallographic coalignment? What determines the surface on which attachment occurs? We conclude that the extent of internal nanoparticle order controls the degree of periodicity and anisotropy In the surrounding electrostatic field. For crystalline particles, the orienting force stemming from the electrostatic field can promote oriented attachment events, although solvent-surface interactions modulate this control."

According to the news editors, the research concluded: "In cases where perfect crystallographic alignment is not achieved, misorientation gives rise to structural defects that can fundamentally modify nanomaterial properties."
