Affinity for Anions Developed in Charcoal by Acid Treatment [PDF]
, 2022 In this study, we report a two-step method that creates at the surface of charcoal acidic groups that remove nitrate from an aqueous solution. The process used in this work with charcoal includes first an acid treatment followed by a heat treatment in a ...

ACS Central Science, 2016 In this report, we introduce artificial enzymes that operate with anion-π interactions, an interaction that is essentially new to nature. The possibility to stabilize anionic intermediates and transition states on an π-acidic surface has been recently demonstrated, using the addition of malonate half thioesters to enolate acceptors as a biologically ...

Causes of metabolic acidosis in canine hemorrhagic shock : role of unmeasured ions [PDF]
, 2007 Introduction: Metabolic acidosis during hemorrhagic shock is common and conventionally considered to be due to hyperlactatemia. There is increasing awareness, however, that other nonlactate, unmeasured anions contribute to this type of acidosis ...

Arylisoquinoline-derived organoboron dyes with a triaryl skeleton show dual fluorescence
Beilstein Journal of Organic Chemistry, 2019 Four new dyes that derive from borylated arylisoquinolines were prepared, containing a third aryl residue (naphthyl, 4-methoxynaphthyl, pyrenyl or anthryl) that is linked via an additional stereogenic axis.

Synthetic applications of hydrazones [PDF]
, 1985 This thesis describes investigations of reactions of hydrazones and their N-anions via the imino carbon atom; these reactions show umpolung reactivity. The conversion of the derived azo products into synthetically useful compounds (e.g.
