Growth and Property Investigations of Two Organic–Inorganic Hybrid Molecular Crystals with High Thermal Stability: 4-Iodoanilinium perchlorate 18-crown-6 and 4-Iodoanilinium Borofluorate 18-crown-6

open access: yesCrystals, 2019
Two new organic–inorganic hybrid molecular single crystals, 4-Iodoanilinium perchlorate 18-crown-6 (1) and 4-Iodoanilinium borofluorate 18-crown-6 (2), with large sizes and high thermal stability were successfully synthesized by solution method ...

The linear polarization of nearby bright stars measured at the parts per million level [PDF]

open access: yes, 2010
We report observations of the linear polarization of a sample of 49 nearby bright stars measured to sensitivities of between ~1 and 4 x 10^-6. The majority of stars in the sample show measurable polarization, but most polarizations are small with 75% of the stars having P < 2 x 10^-5.

Controlling polarization entanglement in biphotons generated with partially spatially coherent pump beam

open access: yesResults in Physics, 2021
We theoretically study the polarization entanglement and the non-local correlations manifested by biphotons using measures as concurrence and CHSH Bell test, generated in the spontaneous parametric down-conversion (SPDC) process for partially spatially ...

MobileViT model-based real-time fiber identification method for cashmere and wool

open access: yesJournal of Engineered Fibers and Fabrics
The physical and morphological characteristics of wool and cashmere fibers exhibit notable similarities, making distinguishing them challenging. In this study, we propose a method based on a lightweight hybrid model called MobileViT, which combines a ...

Dual-band polarization conversions and optical diode based on bilayer T-shaped metamaterial

open access: yesResults in Physics, 2022
In this work, we propose a dual-band optical diode based on a bilayer T-shaped metamaterial. This optical diode can conveniently convert the x-polarized wave to y-polarized one at about 106 THz and convert the y-polarized to x-polarized wave at around ...
