Surveying polar materials in the Inorganic Crystal Structure Database to identify emerging structure types

, 2020
Here we focus on a search for new families of materials that could contain ferroelectrics via crystallographic database mining. Ferroelectrics are insulating polar materials whose polarization can be switched with the application of an electric field ...

A novel emitter: Sensing mechanical stimuli and monitoring total polar materials in frying oil

, 2020
A novel multifunctional D-A type triphenylamine derivative (CPA-TPA) was designed and synthesized via Knoevenagel condensation reaction. It was found with distinct aggregation-induced enhanced emission (AEE) characteristics and solvatochromic performance.

The critical micelle concentration of lecithin in bulk oils and medium chain triacylglycerol is influenced by moisture content and total polar materials.

Food Chemistry, 2018
Effects of different moisture contents and oxidised compounds on the critical micelle concentration (CMC) of lecithin were determined in bulk oils and in medium-chain triacylglycerols (MCT).

First-Principles Computational Screening of Two-Dimensional Polar Materials for Photocatalytic Water Splitting.

ACS Nano
The band gap constraint of the photocatalyst for overall water splitting limits the utilization of solar energy. A strategy to broaden the range of light absorption is employing a two-dimensional (2D) polar material as photocatalyst, benefiting from the ...

Polarizing of piezoelectric material

The Journal of the Acoustical Society of America, 1986
Electrically polarizable material (e.g., PVDF film) is poled by applying an electric field across the film. In the inventive technique, insulation is provided on the surface of the film. In a typical embodiment, a compliant dielectric annulus insulates the polarized region from the edges of the film. This substantially eliminates breakdown at the edges

Shock-Induced Polarization in Polar Materials

1979
Several authors [1–4] have shown that polar materials become polarized by the passage of an intense shock wave. The experimental arrangement is shown in Fig. 1. The polar material is the dielectric of a parallel-plate capacitor. An explosive charge is detonated next to one electrode and the shock transmitted into the dielectric causes a current to flow

An innovative carbon dots polarity probe based on intramolecular charge-transfer for visual monitoring of the total polar materials in frying oil.

Food Chemistry
The presence of Total Polar Materials (TPM) in edible oils is a crucial indicator for assessing oil quality. It is of paramount importance to develop a rapid and dependable technique for monitoring polarity in frying oil.

Vector photochromism in polarization-sensitive materials

Optics Letters, 2014
The phenomenon of vector photochromism was observed in some high-efficient polarization-sensitive materials depending on the radiant exposure of the inducing linearly polarized actinic light. The phenomenon has the purely vector nature because the absorption of the irradiated and unirradiated areas of the material is practically identical when we use ...

Polarization/radiometric based material classification

Proceedings CVPR '89: IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 2003
A technique for identifying the material properties of objects in an image using multiple images taken through a polarizing lens at various rotations in front of a stationary camera (only the filter moves). Using these images, it is possible to obtain the classification of material surfaces at all points on a spectacular highlight.
