Synergistic Enhancement of Electrical‐Thermal Properties in KH550/G‐POSS Functionalized BN/Epoxy Composites for High‐Frequency Transformer Insulation

open access: yesAdvanced Science, EarlyView.
A BN@G‐POSS/EP nanocomposite is developed for high‐frequency transformer insulation in power electronic transformers. Through synergistic interface engineering, it simultaneously enhances thermal conductivity, reduces viscosity, and improves electro‐thermal stability.

Issues in adaptive mesh refinement implementation

open access: yesElectronic Journal of Differential Equations, 2007
Physical phenomena often involve discontinuities and/or localized high-gradient areas. The numerical simulation of these problems and conventional techniques (Finite Elements, Finite Volumes, Finite Differences, and Spectral Methods) with a uniform grid ...

All‐Flex Plasma Patch for In Vivo Delivery of Reactive Species

open access: yesAdvanced Science, EarlyView.
A fully flexible plasma patch enables stable, conformal treatment on complex biological surfaces and enhances transdermal delivery of reactive species. This platform achieves significant tumor suppression in vivo and reveals coordinated regulation of calcium signaling, metabolism, and programmed cell death, providing a promising strategy for safe and ...

Generalised triangular grids in digital geometry

open access: yes, 2004
The hexagonal and the triangular grids are duals of each other. These two grids are the first and second ones in the family of triangular grids (we can call them as one- and two-planes triangular grids). This family comes from the mapping their points to

Growth‐Pathway‐Controlled van der Waals Epitaxy of Phase‐Selective Tin Sulfides

open access: yesAdvanced Science, EarlyView.
Growth‐pathway‐controlled van der Waals epitaxy enables deterministic phase selection and strain engineering in tin sulfide/WSe2 heterostructures. Direct growth of SnS induces substrate‐mediated strain and phase evolution, whereas sequential growth through an SnS2 buffer suppresses strain transfer and stabilizes pristine α‐SnS, revealing a versatile ...

Quantitative modeling of the emergence of macroscopic grid-like representations

open access: yeseLife
When subjects navigate through spatial environments, grid cells exhibit firing fields that are arranged in a triangular grid pattern. Direct recordings of grid cells from the human brain are rare.

ZrO2 Aerogel‐Supported Pd Nanoparticles for Photothermal CO2 Reduction

open access: yesAdvanced Science, EarlyView.
Nanoparticle‐based aerogels are promising catalysts for photothermal reactions due to optical transparency, high surface area, and low thermal conductivity. Here, we present deposition of Pd nanoparticles on ZrO2 aerogel granules by a wet‐impregnation approach.
