Perfluorocarbons as Inert Gases in Homogeneous Sonochemistry

, 1992
The polyatomic inert gases CF4 and C2F6 are efficient in homogeneous sonochemistry. This observation leads to the conclusion that some analogies could exist between sonochemistry and plasma chemistry.

Advances in Unconventional and Sustainable Synthetic Approaches to Benzopyran Scaffolds

The Chemical Record, EarlyView.
This review provides a comprehensive and critical analysis of low‐impact synthetic methodologies reported in the last 8 years (2018–2026) for the construction of benzopyran‐derived scaffolds, such as coumarins, flavones, chromones, chromenes, and chromanes. The benzopyran scaffold is a versatile family of heterocycles found in a wide range of bioactive

Ultrasonic Vibration Assisted Laser Processing: A Hybrid Paradigm for Extreme Surface Enhancement

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Traditional laser processing techniques offer many advantages, but they often encounter limitations such as heat‐affected zones, recast layers, residual tensile stresses, and poor surface finish. The integration of ultrasonic vibration (UV) presents a promising hybrid approach to overcome these challenges by introducing beneficial effects like

Green Preparation of Antimicrobial 1D-Coordination Polymers: [Zn(4,4′-bipy)Cl₂]_∞ and [Zn(4,4′-bipy)₂(OAc)₂]_∞ by Ultrasonication of Zn(II) Salts and 4,4′-Bipyridine

Molecules, 2022
We report on the green preparation of one-dimensional metal coordination polymers by sonochemical approach. The spacer ligand 4,4′-bipyridine was ultrasonicated with chloride or acetate zinc salts to obtain [Zn(4,4′-bipy)Cl2]∞ and [Zn(4,4′-bipy)2(OAc)2]∞,
