From the design of improved batteries to the use of solar and wind power for commodity chemical production, the University of Pittsburgh’s James McKone explores ways that chemical engineering can make the world more sustainable. That’s why his most recent work, investigating ways that the chemical industry can use renewable electricity as its energy source, is featured in the Journal of Materials Chemistry A Emerging Investigators special issue.

The themed issue highlights the rising stars of materials chemistry research, from nanoparticle inks to next-generation solar cells. The featured investigators are early in their careers and were recommended by other experts in the field.  “We’re glad to have James on our faculty and know this honor is well-deserved,” says Steven Little, PhD, chair of the Department of Chemical and Petroleum Engineering at the Swanson School. “It confirms what we already know: that his lab’s work has the potential to influence the direction of future discoveries in energy production, energy storage and beyond.”

Summary:

Raúl Hernández Sánchez's research group is interested in combining supramolecular, inorganic, and materials chemistry to synthesize functional systems that bridge the gap between nanoscale materials and molecular chemistry. Their research is focused on developing new synthetic methodologies to access well-defined nanometer-sized clusters where they can investigate surface structure-function relationships relevant in catalytic and magnetic materials. Other efforts in the Hernández Sánchez (HS) group are aimed at designing and synthesizing structural analogues of carbon nanotubes where exquisite control of the resulting framework allows for properties manipulation.

Students in the HS group will engage in synthetic chemistry and develop familiarity with a range of spectroscopic, electrochemical, crystallographic and magnetic techniques. While rooted in synthetic chemistry, research in the HS group will interface with materials, organic, theory, and physical chemistry.
