Real‐Time Ferroelectric Domain Wall Dynamics During Electric Poling and Depoling

Advanced Science, EarlyView.
Real‐time visualization of domain wall dynamics during alternating‐current poling, direct‐current poling, and electrical depoling in relaxor‐PT ferroelectric single crystals reveals distinct field‐dependent pathways and strong path dependence. Instant polarized light microscopy uncovers reversible domain wall nucleation, motion, and reconfiguration ...

Targeted Multifunctional Fluorine‐Rich Copolymer Coating Design for Ambient‐Stable Prelithiated SiOC Anodes

Advanced Science, EarlyView.
A fluorine‐rich acrylate copolymer, poly (tridecafluorooctyl methacrylate‐co‐methyl methacrylate) (PFMMA), is introduced as a multifunctional protective coating to stabilize the prelithiated SiOC electrodes in humid conditions and preserve unimpeded interfacial ion/charge transport during redox reactions.

Bioinspired Ionochromic Neuromorphic Transistors for Robotic Intelligent Perception

Advanced Science, EarlyView.
A bioinspired ionochromic neuromorphic transistor couples synaptic conductance modulation with reversible color change through voltage‐controlled ion doping in P3HT/ion gel, mimicking biological synaptic plasticity, and chameleon‐like color regulation.

Experimental vibration analysis of the shadow mask

Optics and Lasers in Engineering, 1998
In this paper, the natural frequencies and mode shapes of the shadow mask in a multimedia monitor were measured by the modal testing technique and the amplitude fluctuation (AF) electronic speckle pattern interferometry (ESPI) method. Based on the obtained experimental results, it is advisable to investigate and optimize the assembly conditions of the ...

Shadow Mask Technology

Thin Solid Films, 2002
Abstract We investigate molecular beam epitaxy (MBE) regrowth through shadow masks developed from AlGaAs/GaAs layers on GaAs [001] substrates. Adjusting the directions of the molecular beams relative to the masks results in in situ lateral structuring.

Polarization Guided Mask-Free Shadow Removal

Proceedings of the AAAI Conference on Artificial Intelligence
Shadow is a phenomenon that degenerates image quality and decreases the performance of downstream vision algorithms. Despite the fact that current image shadow removal methods have achieved promising progress, many of them require an externally obtained shadow mask as a necessary part of the input data, which not only introduces additional workload but

Deep Plasma Etching of Glass With a Silicon Shadow Mask

Sensors and Actuators A: Physical, 2008
Inductively coupled plasma reactive ion etching (ICP RIE) has been successfully used for deep (>300 μm) etching of silica and glass with a non-bonded silicon shadow mask.

Effects of shadow‐mask voltage on the discharge in shadow‐mask PDPs

Journal of the Society for Information Display, 2009
Abstract— A new type of ACPDP with a shadow mask (shadow‐mask PDP, SMPDP) has been developed, featuring an effective structure and lower cost. The distinct difference between an SMPDP and a conventional ACPDP is that the dielectric barrier ribs are replaced by a single metal shadow mask.

The Shadow Meets the Mask: Pyramid‐Based Shadow Removal

Computer Graphics Forum, 2008
AbstractIn this paper we propose a novel method for detecting and removing shadows from a single image thereby obtaining a high‐quality shadow‐free image. With minimal user assistance, we first identify shadowed and lit areas on the same surface in the scene using an illumination‐invariant distance measure.

Mirror, Mask, and Shadow

Journal of Management Inquiry, 1993
Using a psychodynamic perspective on intergroup relations, it is suggested that in-groups create enemy out-groups to avoid dealing with internally generated, emotionally laden issues—the group shadow—that exist within the in-group. In-groups develop an exaggerated view of themselves—the social mask—to sustain an illusion of harmony, homogeneity, and ...
