Gustavo Parra-Montesinos Selected as Engineering News-Record Newsmaker

In January, Professor Gustavo Parra-Montesinos was selected as one of the top 25 Engineering News-Record (ENR) Newsmakers of 2010 for his research on link beams with steel-fiber-reinforced concrete.| Short Read

The honor recognizes researchers “who went above and beyond the call of duty to accomplish something that is in the best interest of the construction industry and the general public”. Professor Parra-Montesinos’ research showed that rebar can be reduced by upwards of 40% and will soon be implemented in two forty-story buildings in Seattle. As part of this award, Professor Parra-Montesinos was featured in the cover story of their January 17th issue. He is also invited to an honorary dinner in New York City in April.

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
