Findings advance efficient solar spliting of water into hydrogen fuel
A team of University of Maryland physicists has published new nanoscience advances that they and other scientists say make possible new nanostructures and nanotechnologies with huge potential applications ranging from clean energy and quantum computing advances to new sensor development.
Published in the September 2, issue of Nature Communications the Maryland scientists’ primary discovery is a fundamentally new synthesis strategy for hybrid nanostructures that uses a connector, or “intermedium,” nanoparticle to join multiple different nanoparticles into nanostructures that would be very difficult or perhaps even impossible to make with existing methods. The resultant mix and match modular component approach avoids the limitations in material choice and nanostructure size, shape and symmetry that are inherent in the crystalline growth (epitaxial) synthesis approaches currently used to build nanostructures.
“Our approach makes it possible to design and build higher order [more complex and materially varied] nanostructures with a specifically designed symmetry or shape, akin to the body’s ability to make different protein oligomers each with a specific function determined by its specific composition and shape,” says team leader Min Ouyang, an associate professor in the department of physics and the Maryland NanoCenter.
“Such a synthesis method is the dream of many scientists in our field and we expect researchers now will use our approach to fabricate a full class of new nanoscale hybrid structures,” he says.
Among the scientists excited about this new method is the University of Delaware‘s Matt Doty, an associate professor of materials science and engineering, physics, and electrical and computer engineering and associate director of the UD Nanofabrication Facility. “The work of Weng and coauthors provides a powerful new tool for the ‘quantum engineering’ of complex nanostructures designed to implement novel electronic and optoelectronic functions. [Their] new approach makes it feasible for researchers to realize much more sophisticated nanostructure designs than were previously possible.” he says.
