Scientists home in on pairs of atoms that boost a catalyst's activity

ScienceDaily.com: Nanotechnology News - 22 июня, 2020 - 22:25
A study identified which pairs of atoms in a catalyst nanoparticle are most active in a reaction that breaks down a harmful exhaust gas in catalytic converters. The most active particles contained the biggest proportion of one particular atomic configuration -- one where two atoms, each surrounded by seven neighboring atoms, form pairs to carry out the reaction steps. The results are a step toward engineering cheaper, more efficient catalysts.

Researchers create a photographic film of a molecular switch

ScienceDaily.com: Nanotechnology News - 18 июня, 2020 - 20:23
Molecular switches are the molecular counterparts of electrical switches and play an important role in many processes in nature. Nanotechnologist now produced a photographic film at the atomic level and thus tracked the motion of a molecular building block. The result was a light-controlled 'pedalo-type motion', going forward and backward.
