Scientists break the link between a quantum material’s spin and orbital states

In designing electronic devices, scientists look for ways to manipulate and control three basic properties of electrons: their charge; their spin states, which give rise to magnetism; and the shapes of the fuzzy clouds they form around the nuclei of atoms, which are known as orbitals. Until now, electron spins and orbitals were thought to

New metasurface design can control optical fields in three dimensions

A team led by scientists at the University of Washington has designed and tested a 3D-printed metamaterial that can manipulate light with nanoscale precision. As they report in a paper published Oct. 4 in the journal Science Advances, their designed optical element focuses light to discrete points in a 3D helical pattern. The team’s design

Method to change fundamental architecture of polymers

A Florida State University research team has developed methods to manipulate polymers in a way that changes their fundamental structure, paving the way for potential applications in cargo delivery and release, recyclable materials, shape-shifting soft robots, antimicrobials and more. “We are making a polymer completely change its architecture through a chemical response,” said FSU Assistant

Acoustic energy harnessed to soften shear-thickening fluids

Researchers are using ultrasonic waves to manipulate the viscosity of shear-thickening materials, turning solids to slush — and back again. The study, “Using Acoustic Perturbations to Dynamically Tune Shear Thickening in Colloidal Suspensions,” was published Sept. 17 in Physical Review Letters. Shear-thickening fluids are a class of materials that flow like liquid but solidify when

MicroZed Chronicles: RapidWright Installation — Part One

RapidWright is a tool from Xilinx Research Labs which enables users to manipulate both the synthesized netlist and implementation of 7 Series and up FPGAs and SoCs While not a Xilinx official tool, RapidWright enables improved quality of result (QoR) and productivity. These improvements are provided by RapidWright’s use of modular implementation, overlay and shells.
