Synergistic Molecular Modulation of ππ Stacking for High‐Performance Pitch‐Derived Hard Carbon Anodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A synergistic molecular strategy is demonstrated to disrupt intrinsic ππ stacking in pitch, boosting 6‐fold sulfonation, yielding a hard carbon with 0.371 nm interlayer spacing and maximized closed pores, and achieving a high reversible capacity, remarkable rate capability (205.6 mAh g−1 at 2 A g−1) and cyclic stability.

Mass Spectrometry in Authentication and Forensic Approaches for Determining the Origin of Hazardous Chemicals

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Identification of a chemical agent yields insights into its physicochemical properties. By examining the intrinsic characteristics and environment of a compound, information about its history can be gathered. The main objective of authentication/forensic approaches to chemicals is to trace the history of the compound's origin, regardless of ...
