Total Ponderomotive Force on an Extended Test Body

International Journal of Mathematics and Mathematical Sciences, 2009
Droplets on insulating material suffer a nonvanishing total ponderomotive force because of the inhomogeneity of the surrounding electric field. A series expansion of this total force is proven in a two-dimensional setting by determining the line charge ...

Enhancement of Dielectric Breakdown Strength and Recoverable Energy Density in Three‐Dimensional Heterointerfaces on BaTiO3–PbZrO3–PbTiO3 Films via Room‐Temperature Nano‐Clustering

Advanced Functional Materials, EarlyView.
A room‐temperature aerosol deposition process yields multiphase nano‐clustered dielectric capacitors containing discrete BaTiO3, PbZrO3, and PbTiO3 crystals. This architecture creates three‐dimensional heterointerfaces that induce interfacial charge trapping and effectively inhibit breakdown propagation.

MXene Wrapped Magnetic Mesocrystals for Durable Redox Catalytic Cancer Therapy and Responsive MRI

Advanced Functional Materials, EarlyView.
Conformal wrapping of ultrathin Ti3C2Tx MXene nanosheets on Fe3O4 mesocrystals creates topology‐stabilized Schottky junctions that direct photoinduced electron transfer under NIR irradiation. The unique architecture sustains Fenton catalysis, promotes continuous hydroxyl radical production, and provides photo‐responsive MRI contrast.
