Capturing Reactive Carbanions by Microdroplets

, 2022
Carbanions appear in many organic or biological reactions as fleeting intermediates, prohibiting direct observation or spectroscopic measurement. An aqueous environment is known to rapidly annihilate a carbanion species, reducing its lifetime to as short

Organic nanoparticle-doped microdroplets as dual-modality contrast agents for ultrasound microvascular flow and photoacoustic imaging

Scientific Reports, 2020
Tumor blood vessels are chaotic and abundantly distributed, owing to their heterogeneity. Therefore, imaging techniques which reveal abnormalities of tumor vasculature play significant roles in both mechanistic and clinical diagnostic tumor studies ...

Confined Silver Nanoparticles in Ionic Liquid Films

Molecules, 2023
This work reports the formation of silver nanoparticles (AgNPs) by sputter deposition in thin films of three different ionic liquids (ILs) with the same anion (bis(trifluoromethylsulfonyl)imide) and cation (imidazolium), but with different alkyl chain ...

Water-Derived Radical Species Initiate Six-Electron Oxidation of Cyclic Ketones in Microdroplets. [PDF]

Angew Chem Int Ed Engl
Spontaneous six‐electron oxidation of cyclic ketones to yield dicarboxylic acids/keto acids is achieved in ethanol microdroplets containing about 2% water under ambient conditions without any metal salts, acids, or oxidants. Mechanistic studies show that trace amounts of water and molecular oxygen serve as active oxidants in this transformation ...

One-Step, High-Yield Deconstruction of Kraft Lignin Into a Redox-Active Small Molecule Using Sonicated Emulsive Water Microdroplets. [PDF]

Small
This study reports a rapid (∼20 min), uncatalyzed deconstruction of Kraft lignin (∼14.2 kDa) using sonicated emulsive water microdroplets (SEWMs) in the presence of 2.5 M HNO3. The work demonstrates the combined synergistic effect of sonochemical excitation and microdroplet redox chemistry to induce C─C bond cleavage and reductive nitration to ...

On Serine Octamer Substitution Reactions. [PDF]

Rapid Commun Mass Spectrom
ABSTRACT Rationale Monomeric amino acids substitute into the ionized serine octamer (Ser8), a magic number cluster that exhibits chiral behavior. Small biomolecules, such as amino acids (AA), substitute into the octamer enantioselectively, giving Ser7AAH+ and Ser6AA2H+ favoring clusters of all L‐ or all D‐chirality.
