Hot electrons do the impossible in catalytic chemistry

(Phys.org)—From petroleum refining to food processing, the vast majority of commercial chemical applications involve catalysts to control the rate of chemical reactions. Anything that can increase the efficiency of catalysts ...

DNA as invisible ink can reversibly hide patterns

(PhysOrg.com) -- While most people know of DNA as the building blocks of life, these large molecules also have potential applications in areas such as biosensing, nanoparticle assembly, and building supramolecular structures. ...

Graphene nanoribbons grow due to domino-like effect

(PhysOrg.com) -- While many labs are trying to efficiently synthesize large two-dimensional sheets of graphene, a team of researchers from Sweden and the UK is investigating the synthesis of very thin strips of graphene just ...

Engineers bend light to enhance wavelength conversion

Electrical engineers from the UCLA Samueli School of Engineering have developed a more efficient way of converting light from one wavelength to another, opening the door for improvements in the performance of imaging, sensing ...

Better solutions for making hydrogen may lie just at the surface

A clean energy future propelled by hydrogen fuel depends on figuring out how to reliably and efficiently split water. That's because, even though hydrogen is abundant, it must be derived from another substance that contains ...
