Fast Hydrogel Micro‐Actuators Driven by Electric Fields
Advanced Materials, EarlyView.We report the fabrication of chemically programmable electroactuating microstructures through the first integration of two‐photon polymerization with electrically actuated gelatin methacrylate‐based hydrogels. By tailoring the charge of the polymer network, we demonstrate programmable polarity‐dependent bending, enabling microstructures that ...

Moiré Phase Mapping in Twisted Bilayer Liquid Crystals with Reconfigurable Light Polarization States
Advanced Materials, EarlyView.Twisted bilayer liquid crystals are developed by vertical stacking assembly of two liquid crystals having designer domains and optical properties. These moiré‐symmetry, twisted liquid crystals demonstrate reconfigurable polarization states, moiré patterns and phases controlled by twist angles, providing a route to design active optical devices for ...

Coherent and dissipative spin torques in quantum dots: A unified framework for quantum spin dynamics
Physical Review ResearchThe manipulation of single spins through spin-polarized tunneling opens pathways for quantum control at the atomic scale. We present a theoretical framework describing spin transfer, spin torques, and spin resonance in molecular quantum dots weakly ...

University Spin-Off's Transfer Speed: Analyzing the Time from Leaving University to Venture [PDF]
For academic spin-offs I analyze the length of time between the founder's leaving of academia and the establishment of his firm. Technology transfer can take place even years after leaving the mother institution. A duration analysis reveals that a longer

Advanced Materials, EarlyView.The interfacial spin‐orbit interaction in single‐crystalline Fe1−xCox thin films grown on GaAs(001) can be continuously tuned via alloying. Using spin‐orbit ferromagnetic resonance, the authors find that the interfacial spin‐orbit fields exhibit a nonmonotonic dependence on Co concentration, with a minimum at 20% Co. ABSTRACT The discovery of intrinsic

Detection of radiation torque exerted on an alkali-metal vapor cell
AIP Advances, 2019 We have developed a torsion balance to detect the rotation of a cell containing spin-polarized gaseous atoms to study angular momentum transfer from gaseous atoms to solid. A cesium vapor cell was hung from a thin wire in a vacuum chamber, and irradiated

Current‐Induced Domain Wall Dynamics in Pt/Co/Ni/Co Nanoribbons With Curvilinear Cross‐Sections
Advanced Materials, EarlyView.3D curvilinear magnetic racetrack nanoribbons are formed with concave and convex cross‐sections using an advanced multi‐photon 3D printer. The curvature is shown to strongly affect current‐induced domain wall motion along the nanoribbons. In nanoribbons with cross‐sections that have both concave and convex segments, the velocities of domain walls with ...
