Effects of Electric Fields on Forces between Dielectric Particles in Air
… electric fields on the forces between two dielectric microspheres. In this work we measured the DC and AC electric field-induced forces and adhesion force between two barium titanate (BaTiO?) glass microspheres in a low humidity environment by this technique. The objective here is to find …

Particle-Based Triboelectric Vibration Sensor for Speech Recognition and Remote Machine Condition Monitoring
… comprises a flat round capsule filled with dielectric particles, with an inner tribo-layer backed by electrodes. When attached to a vibrating structure, particle impacts on the inner surfaces cause opposite charges to form, generating an alternating voltage through the dynamic motion of the …

Electrohydrodynamic interactions of colloidal particles undergoing Quincke rotation
… suspensions, denotes the spontaneous rotation of dielectric particles immersed in a slightly dielectric liquid when subjected to a high enough DC electric field. Quincke rotation occurs when the charge relaxation time of the particles is greater than that of the fluid medium, causing the particles …

Interactions of Organic Fluorophores with Plasmonic Surface Lattice Resonances
… in the solid metal. When described as quasiparticles in a manner analogous to phonons (lattice vibrations, propagating oscillations in the positions of atomic nuclei), these electron-density oscillations are referred to as plasmons, specifically volume or bulk plasmons when they exist and …
