Katya Stonkevitch presents Additive Manufacturing of Polymer-Derived Ceramic Matrix Composites for AAAFM-UCLA 2021.
HRL Laboratories will design architected materials to be used on the leading edges of hypersonic aircraft as part of the Materials Architectures and Characterization for Hypersonics or MACH program from DARPA. Hypersonic vehicles fly at least five times the speed of sound. Leading edges are essential design features because they enable long-range travel at extremely high velocities while maintaining vehicle maneuverability.
Dan Sievenpiper earned his PhD in 1999 from UCLA, where he invented the high-impedance electromagnetic surface. Dan joined HRL Laboratories later that year, and during the next 11 years, Dan and his team developed new electromagnetic structures with an emphasis on small, conformal, tunable, and steerable antennas.
HRL Laboratories, LLC, has announced the launch of its first podcast, HRL’s History of the Future, which will focus on the famed Hughes Research facility’s past and HRL’s present advancements in science and technology.
HRL researchers originally made headlines with a famous image of a metal microlattice structure resting atop an unaffected dandelion. Now the material has been vetted and confirmed by the Guinness book as having no peer among metals when it comes to weight.
An HRL Laboratories, LLC, research team has published a paper in the March issue of MRS Bulletin, a journal of the Materials Research Society, that sits squarely at the intersection of materials science and quantum computing. The paper, “Metamorphic Materials for Quantum Computing,” explores the demands that silicon-germanium (SiGe) quantum dot heterostructures impose on the underlying substrate, the ways in which the metamorphic substrate’s properties impact device performance, and how performance limitations may be overcome.
