Imperfection is OK for better MOFs

Perfect crystals are not necessarily the most useful. Defects in the ordered crystalline structure of metal-organic frameworks (MOFs) could tailor these versatile materials for specific applications. KAUST researchers have ...

Heterometallic copper-aluminum super atom discovered

On the outside, a cluster of 55 copper and aluminum atoms looks like a crystal, but chemically, it has the properties of an atom. The heterometallic superatom, which chemists of the Technical University of Munich (TUM) have ...

How metal clusters grow

First the nucleus, then the shell: Researchers from Marburg and Karlsruhe have studied stepwise formation of metal clusters, smallest fractions of metals in molecular form. The shell gradually forms around the inner atom ...

Boron-based atomic clusters mimic rare-earth metals

Rare Earth elements, found in the f-block of the periodic table, have particular magnetic and optical properties that make them valuable commodities. This has been particularly true over the last thirty years as more technologies ...

How many gold atoms make gold metal?

Researchers at the Nanoscience Center at the University of Jyväskylä, Finland, have shown that dramatic changes in the electronic properties of nanometre-sized chunks of gold occur in well-defined size range. Small gold ...

Catalytic gold nanoclusters promise rich chemical yields

(Phys.org) —Old thinking was that gold, while good for jewelry, was not of much use for chemists because it is relatively nonreactive. That changed a decade ago when scientists hit a rich vein of discoveries revealing that ...
