Precursor Mineral Phases of Forming Mollusk Shell Nacre: A Study of Hydrated Samples
Advanced Functional Materials, EarlyView.Mineral, organic phase, and water are the essential components in mollusk shell nacre formation. Their interplay is not well understood, because the hydrated material is difficult to observe at high resolution, under close to native conditions. Forming nacre is studied using environmental and cryo‐electron microscopy and hydrated ACC phases, together ...

Electroactive Liquid Crystal Elastomers as Soft Actuators
Advanced Functional Materials, EarlyView.Electroactive liquid crystal elastomers (eLCEs) can be actuated via electromechanical, electrochemical, or electrothermal effects. a) Electromechanical effects include Maxwell stress, electrostriction, and the electroclinic effect. b) Electrochemical effects arise from electrode redox reactions.

Trapping of light with angular orbital momentum above the light cone
Advanced Electromagnetics, 2017 We consider bound states in the radiation continuum (BSC) above the light cone in an one-dimensional periodic array of dielectric spheres in air. The BSCs are classified by orbital angular momentum m, Bloch wave vector β directed along the array, and ...

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics
Advanced Functional Materials, EarlyView.Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Cone inputs to murine striate cortex
BMC Neuroscience, 2008 Background We have recorded responses from single neurons in murine visual cortex to determine the effectiveness of the input from the two murine cone photoreceptor mechanisms and whether there is any unique selectivity for cone inputs at this higher ...

Joining-splitting interaction of non-critical string
, 2002 The joining--splitting interaction of non-critical bosonic string is analyzed in the light-cone formulation. The Mandelstam method of constructing tree string amplitudes is extended to the bosonic massive string models of the discrete series. The general

Universal light cone commutator [PDF]
Physics Letters B, 1970 Abstract An operator generalization of a previously considered universal light cone current commutator is proposed. It involves the vector Jμa(x) and scalar Sa(x) elements of the U(12) algebra as well as the the vector Pμ and scalar M2 elements of the Poincare enveloping algebra. The requirements imposed by the proposal on the light cone behaviour of

Selection Strategies for Flexible Pressure Sensor Electrode Materials Toward Ultrafast Response
Advanced Functional Materials, EarlyView.This study reveals, for the first time, how the electrode–organic interface governs the temporal performance of flexible pressure sensors. By pairing high‐conductivity CVD PEDOT with commonly used metal electrodes, the authors demonstrate that interfacial energy alignment dictates microsecond‐scale response, providing a straightforward design strategy ...
