Mechanistic Insight into the Thermochromic Emission of One‐Dimensional Platinum(II) and Palladium(II) Complex Crystals

ChemPlusChem, Volume 90, Issue 5, May 2025.
One‐dimensional Pt(II) complexes are known to exhibit significant thermochromic emissions in the crystalline state. This phenomenon offers valuable insights into the excited states of Pt(II) complexes. This review focuses on the thermochromic mechanisms of one‐dimensional Pt(II) and Pd(II) complexes from the viewpoint of the relationship between ...

Modeling of the formation of short-chain acids in propane flames [PDF]

arXiv, 2009
In order to better understand their potential formation in combustion systems, a detailed kinetic mechanism for the formation of short-chain monocarboxylic acids, formic (HCOOH), acetic (CH3COOH), propionic (C2H5COOH) and propenic (C2H3COOH)) acids, has been developed. Simulations of lean (equivalence ratios from 0.9 to 0.48) laminar premixed flames of

Amaranthus spinosus Linn. Extract as an Innovative Strategy to Regulate Biomarkers for Ovarian Hyperthecosis via Circular RNA (hsa‐circ‐0001577): Evidence From Biochemical, Metabolomics, Histological, and Phytochemical Profiling

Food Science &Nutrition, Volume 13, Issue 5, May 2025.
A significant improvement in hormonal and oxidative stress biomarkers was observed in rats treated with Amaranthus spinosus, especially at high doses, after induction of ovarian hyperthecosis. Amaranthus spinosus could be a management approach for ovarian hyperthecosis via regulating circRNA (hsa‐circ‐0001577), disturbed hormonal balance, and ...

Discovery Of Copper Catalyst For New Chemical Polishing Acid On Superconducting Niobium [PDF]

arXiv, 2020
High field Q-slope (HFQS) seriously limits the high gradient performance of the buffered chemically polished (BCP) superconducting radio frequency (SRF) niobium cavities. The direct cause or mechanism is not yet fully understood. In our recent extensive data analysis, we concluded that the potential root cause could be nitrogen contamination on the ...
