Advanced Functional Materials, EarlyView.The plasma edge of transparent conducting oxide SrNbO3 shifts from ∼2 eV in the visible range to 1.37 eV in the near‐infrared region by off‐stoichiometry using the vacancy sites as quasi‐substitutional virtual elements. This work advances the stoichiometry engineering of perovskite oxides using oxide molecular beam epitaxy, allowing synthesis beyond ...

Conductivity and permittivity imaging at 3.0 t [PDF]
Concepts in Magnetic Resonance Part B: Magnetic Resonance Engineering, 2012 AbstractTissue conductivity and permittivity are critical to understanding radio frequency (RF) power deposition during magnetic resonance imaging (MRI). These electrical properties are also important in treatment planning of RF thermotherapy methods (e.g., RF hyperthermia).

Vivid Structural Coloration in Transparent MXene‐Cellulose Nanocrystals Composite Films
Advanced Functional Materials, EarlyView.Vivid structural coloration in reflectance and high transparency in transmittance modes are observed in biopolymer‐layered composite films. The ultrathin multilayered structures have unique optical appearance, near‐infrared bandgap, and strong optical reflection caused by alternating MXene and cellulose nanocrystals layers with high refractive index ...
