There is a growing interest in and demand on analytical chemistry for application scenarios from ex situ analysis after sample collection to in situ, operando, or bedside analysis without sample pretreatment. Our annual Special Issue on Fundamental and Applied Reviews in Analytical Chemistry provides authoritative critical reviews on selected topics, including the highlights and current ...
The focus of this review is to provide an overview of the nomenclature, structure, and properties of perfluoroalkyl and polyfluoroalkyl substances (PFAS) that dictate the selection of analytical methods for analyzing PFAS in treated semiconductor wastewater. The review is organized by introducing the fundamental concepts of how structure dictates the physical-chemical properties of PFAS and ...
Green analytical chemistry focuses on making analytical procedures more environmentally benign and safer to humans. The amounts and toxicity of reagents, generated waste, energy requirements, the number of procedural steps, miniaturization, and automation are just a few of the multitude of criteria considered when assessing an analytical methodology’s greenness. The use of greenness ...
These analytical models provide valuable insights into the behavior of casing-cement sheath-formation systems under various conditions. Elasticity models focus on stress distribution and integrity factors, while elastic-plasticity models consider plastic deformation and micro annulus.
The structure of the lignin in wheat straw has been investigated by a combination of analytical pyrolysis, 2D-NMR, and derivatization followed by reductive cleavage (DFRC). It is a p-hydroxyphenyl-guaiacyl-syringyl lignin (with an H:G:S ratio of 6:64:30) associated with p-coumarates and ferulates. 2D-NMR indicated that the main substructures present are β-O-4′-ethers (∼75%), followed by ...
