Investigation of a Micro Two-Phase Flux-Switching Motor
EnergiesThis paper presents the world’s smallest two-phase flux-switching motor (FSM), featuring a four-pole stator and a two-pole rotor with a non-uniform air gap design. The FSM offers several advantages, including a compact size, simple structure, and ease of

Management of Gingival Overgrowth During Orthodontic Treatment Using a Blue Laser: A Case Report
Clinical Case Reports, Volume 14, Issue 5, May 2026.ABSTRACT Blue laser‐assisted management of gingival overgrowth demonstrated excellent healing with minimal postoperative scarring, along with reduced pain and bleeding, and a relatively shorter surgical time. Despite a partial relapse observed after 3 months, this incisional intervention facilitated the orthodontist's ability to achieve a more ...

Fast Simulation and Optimization Design of a Slotless Micro-Motor for High-Speed and High-Flow Pumps
MachinesThe effective part of the winding in a slotless motor varies across different axial sections of the motor, resulting in a three-dimensional structure. Therefore, it is not feasible to simply use the single-section simulation method of conventional radial

Active Particles in Tunable Compressible Environments
Small Science, Volume 6, Issue 5, May 2026.Gold‐capped active microparticles powered by electric fields plough their way through a matrix of repulsive spheres, shoveling them aside. At high densities and field strengths, an initial strong direction fluctuation may compress the matrix asymmetrically and lead to an asymmetric reaction favoring sustained turns to the same side (spontaneous ...
