Charge‐Assisted Hydrogen‐Bonded Organic Frameworks: From Crystal Engineering to Multifunctional Materials

open access: yesChemistry–Methods, EarlyView.
This review briefly highlights the construction of charge‐assisted hydrogen‐bonded organic frameworks using a variety of organic acids and organic bases, which feature different hydrogen‐bonding motifs, along with their applications, including negative linear compressibility, proton conduction, atmospheric water harvesting, gas adsorption and ...

Sequential Ester Homologation–Nucleophile‐Guided Functionalization: A Chemoselective Access to Thioesters, Amides, and Acids

open access: yesChemistry–Methods, EarlyView.
The homologation of esters—in the presence of a lithium carbenoid—to thioesters, amides, and carboxylic acid is reported. By controlling the tetrahedral intermediate collapsing and promoting a series of rearrangements ultimately leading to a high electrophilic ketene, the subsequent incorporation of S‐, N‐, and O‐nucleophilic elements furnishes the ...

An assessment of organic solvent based equilibrium partitioning methods for predicting the bioconcentration behavior of perfluorinated sulfonic acids, carboxylic acids, and sulfonamides [PDF]

open access: yes, 2009
SPARC, KOWWIN, and ALOGPS octanol-water partitioning (log K~ow~) and distribution (log D) constants were calculated for all C~1~ through C~8~ and the straight chain C~9~ through C~15~ perfluoroalkyl sulfonic acids (PFSAs) and carboxylic acids (PFCAs ...

Harnessing Fluorine Chemistry: Strategies for Per‐ and Polyfluoroalkyl Substances Removal and Enrichment

open access: yesChemPlusChem, EarlyView.
The high fluorine content in per‐ and polyfluoroalkyl substances (PFAS) gives them unique properties, leading to their widespread use in industrial applications and consumer products, but also creating environmental challenges . A thorough understanding of PFAS fluorine chemistry is crucial for developing effective concentration technologies ...

Asymmetric Benzene Sulfonamide Sodium Salt Enabling Stable Cycling in Solid‐State Sodium Metal Batteries

open access: yesChemSusChem, EarlyView.
A novel sodium salt, sodium (benzenesulfonyl)(trifluoromethanesulfonyl) imide, is developed for all‐solid‐state sodium metal batteries. It offers a high sodium‐ion transference number and stability with sodium metal . Combined with poly(ethylene oxide), it forms strong solid polymer electrolytes that suppress dendrite growth and polarization.

Degradation kinetics of six sulfonamides in hen eggs under simulated cooking temperatures [PDF]

open access: yesJournal of the Serbian Chemical Society, 2011
Six sulfonamides, i.e., sulfadiazine, sulfadimethoxine, sulfamerazine, sulfamethazine, sulfamethoxazole and sulfamonomethoxine, were applied to spike whole hen eggs at 0.1 mg kg-1 eggs.
