Nanophotonics, Volume 15, Issue 5, 16 March 2026.Spin–orbit interaction (SOI) of light is exploited to generate helicity‐dependent complex rotational and revolution dynamics in optical tweezers. At the trap center, particle rotation is governed by the direct helicity that follows the input polarization.

ChemPhysChem, Volume 27, Issue 5, 13 March 2026.We studied molecular dynamics in four tetrafluoridoborate salts by means of nuclear magnetic resonance. Characteristical motions in these systems are thermally‐activated reorientations of BF4− ions. We determine the activation energies for these processes and compare the dynamics with those in borohydride systems that share the tetrahedral geometry of ...

Cycloidal Magnetic Gear Speed Reducer
Modern Mechanical Engineering, 2013 A cycloidal speed reducer employing gears with permanent magnets acting as teeth is described. The magnets, which have their axes radially oriented in both the orbiting gear and the fixed internal gear, are inserted in holes drilled in nonmagnetic rims without protruding from the cylindrical exposed surfaces. Because the orbiting gear is not restrained
