Reduction of plyatomic ion interferences in indictively coupled plasma mass spectrometry with cryogenic desolvation

, 1993
A desolvation scheme for introducing aqueous and organic samples into an argon inductively coupled plasma is described; the aerosol generated by nebulizer is heated (+140 C) and cooled ({minus}80 C) repeatedly, and the dried aerosol is then injected into

Ternary Crosslinking Builds Nanosheet Hard Carbon and Interfacial Polarization Regulates Na⁺ Kinetics in Hard Carbon Anodes

Carbon Energy, EarlyView.
Nanosheet Hard Carbon for Fast Na+ Storage ABSTRACT Hard‐carbon anodes for sodium‐ion batteries are often constrained by low initial Coulombic efficiency, severe interfacial polarization, and sluggish Na⁺ kinetics, especially when porosity engineering amplifies electrolyte consumption.

Deciphering Polarity Effects of Polymer to Regulate Li+ Ionic Environment in Solid Polymer Electrolytes for Solid‐State Lithium Batteries

Carbon Energy, EarlyView.
We elucidate the fundamental influences of polymer polarity on Li+ ionic environments in solid polymer electrolytes by considering four critical components: Li+, FSI−, residual solvents, and polymer matrix. Beyond facilitating LiFSI dissociation and Li+ transport, our findings underscore previously overlooked roles of polymer polarity, thereby ...

Desolvation Inability of Solid Hydrates, an Alternative Expression for the Gibbs Free Energy of Solvation, and the Myth of Freeze-Drying

The term “desolvation inability” is proposed in order to describe the alteration of the original chemical structure of a solute (“decomposition”) prior to the solvent’s full removal upon the heating of the solvate.

Synergistically Accelerating Zn2+ Transport and Desolvation Through Cation‐Deficient Ion Channels in High‐Performance Zn Metal Batteries

Carbon Energy, EarlyView.
The novel ITO protective layer enables ultra‐stable Zn metal anodes. By synergistically accelerating Zn2+ desolvation and Zn2+ transport via its unique structure, the ITO layer suppresses dendrites and side reactions. This results in exceptional stability for over 6000 h at 2 mA cm–2 and stable operation in Zn ||MnO2 full‐cell configurations.

Getting the Big Ones to Pack: Crystal Structure of Vitamin K2 With a Chaperone

Chemistry – A European Journal, EarlyView.
A method for obtaining co‐crystals of medium‐size organic molecules and ‐tetrakis(2‐fluoro‐4‐methoxyphenyl)adamantane (TFM) as chaperone was developed. This method yielded a high‐resolution x‐ray crystal structure of menaquinone MK‐4 (vitamin K2), in which layers of chaperone and vitamin guest molecules are found.
