Advanced Functional Materials, EarlyView.Here, we present a high‐density PEDOT eutectogel electrode array for enhanced body surface gastric mapping. Silver electrodes are blade‐coated onto flexible substrates, followed by electrogelation of PEDOT:PSS and the deposition of a PEDOT:LS eutectogel.

Scientific Reports, 2017 Light extraction from a thin planar layer can be increased by introducing a two-dimensional periodic pattern on its surface. This structure, the so-called photonic crystal (PhC) slab, then not only enhances the extraction efficiency of light but can ...

Azimuthally Varying Guided Mode Resonance Filters
Micromachines, 2012 New and novel sensing schemes require optical functions with unconventional spatial light distributions, as well as complex spectral functionality. Micro-optical elements have shown some flexibility in their ability to spatially encode phase information ...

Advanced Functional Materials, EarlyView.Amorphous calcium phosphate (ACP) microparticles with long‐term and thermal stability are prepared with or without collagen using a scalable one‐pot spray‐drying process. Under simulated physiological conditions, they crystallize into biomimetic bone mineral and, when combined with collagen, form extrudable, fibrillar bone‐like 3D constructs.

Excitation of guided waves in layered structures with negative refraction
, 2004 We study the electromagnetic beam reflection from layered structures that include the so-called double-negative materials, also called left-handed metamaterials.

Polarising anisotropic fibres and their leaky modes
Electronics Letters, 1985 Anisotropic fibres may be analysed in terms of equivalent isotropic fibres. This gives a clear physical picture of propagation, particularly the tunnelling loss mechanisms of leaky modes and the effect of a finite cladding on such modes. Slightly tilting the cladding optical (stress) axis relative to that of the core axis greatly amplifies the leakage ...

Advanced Functional Materials, EarlyView.Ferroelectricity in thin HfO2‐based films offers great possibilities for next‐generation neuromorphic memory devices. There, the response to subcoercive voltage signals is driven by the movement of mobile interfaces and their interaction with crystal defects – a yet rather unexplored aspect, which we shed light on and gain new insights into the complex

Oscillatory Modes of a Prominence-PCTR-Corona Slab Model
, 2007 Oscillations of magnetic structures in the solar corona have often been interpreted in terms of magnetohydrodynamic waves. We study the adiabatic magnetoacoustic modes of a prominence plasma slab with a uniform longitudinal magnetic field, surrounded by ...
