'Diamonds from the sky' chemistry converts greenhouse gas into valuable nanocarbon materials

Nanowerk.com - 19 июля, 2019 - 13:25
Carbon nano-onions (CNOs), a less studied morphology of carbon nanomaterials, are exotic structures with extraordinary properties and numerous applications. These applications have been largely ignored due to their high synthesis cost. Researchers now have produced inexpensive, stable carbon-nano onions directly from carbon dioxide. The carbon dioxide reactant replaces nano-diamonds as the reactant to form the nano-onions. The source of CO2 to produce these CNOs can be the consumption of industrial flue gas or CO2 directly captured from the air.

Adding a polymer stabilizes collapsing metal-organic frameworks

Nanowerk.com - 18 июля, 2019 - 19:51
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 - 17 июля, 2019 - 20:28
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.
