Properties Depend On Cluster Size

Numbers of edge atoms dictate physical and chemical properties of nanoparticles
Department: Science & Technology

What a difference a few atoms can make.

Tiny variations in the numbers of atoms along the edges of molybdenum disulfide nanoparticles can profoundly influence the crystal's atomic-scale structure and coordination, electronic properties, and other characteristics, researchers in Denmark have shown. The findings may lead to improvements in MoS2-based desulfurization catalysts for fuel cleanup and to advanced lubricants and other applications.

With legislation in the U.S., Europe, Japan, and elsewhere calling for ever lower levels . . .
