The phenomenological electromagnetic force density
, 1981 The "current loop" model for a magnetic dipole is thoroughly examined in connection with the electromagnetic force density in material media. An updated and theoretically consistent expression for that force density is presented which differs from the ...

Advanced Materials, EarlyView.This work presents soft, degradable hydrogel microcarriers that combine magnetic responsiveness with the ability to host multiple therapeutic and cellular components. Produced by droplet microfluidics, the carriers maintain structural integrity during manipulation, permit controlled breakdown under physiological conditions, and enable guided motion for

Electromagnetic Force Calculations with ROXIE
, 2001 Recent magnet-design work has made necessary the detailed calculation of electromagnetic forces on iron parts. With the coupling method between boundary-elements and finite-elements these forces can be accurately calculated by means of the Maxwell stress

Near‐Unity Chiral Lasing Enabled by Quasi‐Bound States in the Continuum
Advanced Materials, EarlyView.Nanoimprinted chiral array that supports bound states in the continuum is doped with an efficient non‐chiral molecule (Rhodamine‐B) acting as gain medium to produce fully circularly polarized lasing emission. The chiral lasing wavelength can be tuned across the emission band of Rhodamine‐B by adjusting the coating thickness of the TiO2 high refractive ...

The motion of point particles in curved spacetime
, 2011 This review is concerned with the motion of a point scalar charge, a point electric charge, and a point mass in a specified background spacetime. In each of the three cases the particle produces a field that behaves as outgoing radiation in the wave zone,

Electromagnetic force with explicit relativistic symmetry
Although Lorentz force is a one of basic examples of special relativity, there is a possible alternative candidate for electromagnetic force which has even more relativistic ...

Advanced Materials, EarlyView.Inspired by the octopus and the golden wheel spider, soft robots with liquid crystal elastomer arc fibers as appendages are fabricated to transcend surface constraints through an elevated center of mass and minimal contact footprints. By leveraging curvature‐encoded deformation‐recovery cycles, these robots exhibit contractile, torsional, and flexural ...

The electromagnetic armature force in railguns
, 1995 Plasma armature transaugmented and muzzle-fed railgun experiments were performed in the UTSI 2.4 m, 1 cm bore diameter railgun. These experiments were evaluated with a performance model that included the simple electromagnetic force equation for the ...

Nocturnal Intraocular Pressure Monitoring With a Soft Contact Lens Sensor for Glaucoma Management
Advanced Materials, EarlyView.A soft contact lens sensor enables continuous, noninvasive monitoring of nocturnal intraocular pressure (IOP) under closed‐eye sleep conditions. By integrating a highly compliant inductive–capacitive circuit onto a commercial lens, the device achieves record sensitivity and stable performance.
