Polar Layered Bismuth‐Rich Oxyhalide Piezoelectrics Bi4O5X2 (XBr, I): Efficient Piezocatalytic Pure Water Splitting and Interlayer Anion‐Dependent Activity

Advanced Functional Materials, 2023
Piezocatalytic pure water splitting for H2 evolution carries the virtues of efficacious utilization of mechanical energy, easy operation, and high value‐added products, while lacking desirable piezoelectrics for high chemical energy production. Here, two

Shock‐Induced Polarization of Materials

Combustion, Explosion and Shock Waves, 2004
A new computational method of calculating signals of shock‐induced electric polarization of materials is proposed and used to analyze previous experimental results on the shock‐induced electric polarization of Plexiglas. Experimental results on the shock‐induced electric polarization of granite are presented.

Multimodal-Responsive Circularly Polarized Luminescence Security Materials

Journal of the American Chemical Society, 2023
Nations, industries, and aspects of everyday life have undergone forgery and counterfeiting ever since the emergence of commercialization. Securing documents and products with anticounterfeit additives shows promise for authentication, allowing one to combat ever-increasing global counterfeiting.

Multi-functional Materials with Polarization

2007 Sixteenth IEEE International Symposium on the Applications of Ferroelectrics, 2007
Multifunctional materials can respond to more than one external stimulus. One important family of such materials would be those with magnetization-polarization interactions: however, prior searches for such systems with strong exchange have proven elusive.

Mercurous chloride polarizer material

1974
Abstract : The report covers a feasibility study on the potential use of mercurous chloride crystals for construction of prism polarizers, primarily for the infrared region of the spectrum. In particular, the research has consisted of crystal growth from the vapor phase and optical characterization of the absorption, dichroism, and birefringence ...

Polarization Switching for Ferroelectric Materials

Aerospace, 1996
Abstract In this paper we present the results of an experimental study focused on understanding the strain concentrations arising due to nonlinear phenomena associated with polarization switching. A Moire interferometry technique is used to measure the normal and shear strains of a PZT-5H piezoceramics undergoing 180° and 90° switching ...

Polarization modulator using ferrofluid material

SPIE Proceedings, 1990
We show a Faraday polarisation modulator whose frequency ranges from 20Hz to 40KHz. This device can be used, among other applications, in high precision polarimetric and ellipsometric setups (azimuthal polarisation detection).

Polarization current in fluoropolymer materials

Proceedings of 1995 Conference on Electrical Insulation and Dielectric Phenomena, 2002
Studies on Thermally Stimulated Polarization Currents (TSPC) in fluoropolymer films are presented in this paper. The influences of poling field, heating rate and electrode material on TSPC are investigated. Results show that higher poling fields yield higher currents.

Olefins and Vinyl Polar Monomers: Bridging the Gap for Next Generation Materials.

Angewandte Chemie, 2019
The inherent differences in reactivity between activated and non-activated alkenes prevents copolymerization using established polymer synthesis techniques. Research over the past 20 years has greatly advanced the copolymerization of polar vinyl monomers
