Professor Peretz P. Friedmann, the François-Xavier Bagnoud Professor at the University of Michigan, is this year’s honored recipient of the Dr. Alexander Klemin Award, the highest honor the AHS International bestows on an individual for notable achievement in advancing the field of vertical flight aeronautics.

In a career that spans 45 years, Friedmann has made outstanding and lasting original contributions to rotary-wing aeroelasticity, on-blade control of vibration and noise, optimum design of low vibration helicopter rotors, rotorcraft aeromechanics and unsteady aerodynamics. These contributions have advanced the understanding of rotorcraft aeromechanical behavior and have had a major impact on modern helicopter design.

Researchers
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
