Adding a polymer stabilizes collapsing metal-organic frameworks

NanoWerk.com - Thu, 07/18/2019 - 20:51
Porous metal-organic frameworks (MOFs) have many applications like carbon capture and water-cleaning. However, MOFs with large pores tend to collapse. Chemists and chemical engineers have now solved the problem by adding small amounts of a polymer into the MOF pores, an act that impedes pore collapse.

A New Spin On DNA

ScienceDaily.com: Nanotechnology News - Wed, 07/17/2019 - 21:28
For decades, researchers have chased ways to study biological machines. Every mechanical movement -- from contracting a muscle to replicating DNA -- relies on molecular motors that take near-undetectable steps. Trying to see them move is like trying to watch a soccer game taking place on the moon. Now, with DNA origami helicopters, researchers have captured the first recorded rotational steps of a molecular motor as it moved from one DNA base pair to another.

High magnetic field of 10T during activated carbon production improves micropore capacity by 35%

ScienceDaily.com: Nanotechnology News - Wed, 07/17/2019 - 18:53
Carbon materials such as nanotubes, graphene, activated carbon and graphite are in high demand. Researchers set out to create more efficient forms of activated carbon by utilizing the superconducting magnets, thus increasing the volume of pores in the activated carbon by 35%. Many other materials that have negative magnetic susceptibility may also be manufactured using this effective procedure with the superconducting magnets to control for better properties.

New spin on molecular oxygen

ScienceDaily.com: Nanotechnology News - Wed, 07/17/2019 - 18:53
Reactive molecular oxygen singlets have a multitude of uses in chemistry and medicine, but they are less abundant than non-reactive oxygen triplets. A multinational research team has developed a novel method of producing reactive molecular oxygen through controlled, reversible bond formation between two oxygen atoms using atomic force microscopy. In addition, the researchers could alter the charge of individual oxygen atoms, presumably changing oxygen spin in the process.
