Effect of Poly(3-Hexylthiophene):Mixed Fullerene Indene-C60 Multi-Adducts Ratios on the Performance of Organic Solar Cells [PDF]

open access: yesIranian Journal of Materials Science and Engineering, 2023
In this study, poly(3-hexylthiophene) (P3HT) and fullerene Indene-C60 multi-adducts (ICxA) were blended to create a formulation as a solution and thin films, which were prepared under ambient conditions.

Variational Mode Decomposition for Raman Spectral Denoising

open access: yesMolecules, 2023
As a fast and non-destructive spectroscopic analysis technique, Raman spectroscopy has been widely applied in chemistry. However, noise is usually unavoidable in Raman spectra. Hence, denoising is an important step before Raman spectral analysis. A novel

Raman cross section of spin ladders

open access: yes, 2001
We demonstrate that a two-triplet resonance strongly renormalizes the Raman spectrum of two-leg spin ladders and moreover suggest this to be the origin of the asymmetry of the magnetic Raman continuum observed in CaV2O5.Comment: 2 pages, 1 ...

Identification Characteristics of Natural and Synthetic Amethyst by Infrared and Polarized Raman Spectroscopy

open access: yesYankuang ceshi, 2019
BACKGROUND The identification of natural and synthetic amethyst is still a challenge for gemological laboratories either at home or abroad. Previous studies focus on twinning, color band, inclusions and the infrared spectrum.

Higgs Mode and Magnon Interactions in 2D Quantum Antiferromagnets from Raman Scattering

open access: yes, 2015
We present a theory for Raman scattering on 2D quantum antiferromagnets. The microscopic Fleury-Loudon Hamiltonian is expressed in terms of an effective $O(3)$ - model.

Effect of low-Raman window position on correlated photon-pair generation in a chalcogenide Ge11.5As24Se64.5 nanowire [PDF]

open access: yes, 2015
We investigated correlated photon-pair generation via spontaneous four-wave mixing in an integrated chalcogenideGe11.5As24Se64.5photonicnanowire. The coincidence to accidental ratio, a key measurement for the quality of correlated photon-pair sources ...

Trace Nickel Activated Biphasic Core‐CuOii/Shell‐CuOi Secondary Microspheres Enable Room Temperature Parts‐Per‐Trillion‐Level NO2 Detection

open access: yesAdvanced Engineering Materials, EarlyView.
An idea of designing novel sensors is proposed by creating appropriate Schottky barriers and vacancies between isomorphous Core‐CuOii/ Shell‐CuOi secondary microspheres and enhancing catalytic and spill‐over effects, and electronegativity via spontaneous biphasic separation, self‐assembly, and trace‐Ni‐doping.

Effect of Fe Content on Raman Spectral Characteristics of Dolomite

open access: yesYankuang ceshi, 2023
BACKGROUNDDolomite is a common carbonate mineral in sedimentary rocks, and dolomite rock serves as an important reservoir rock for oil and gas. However, the production of synthetic dolomite under normal temperature and pressure is not yet possible, the ...
