Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Influence of crosslinker on the properties of terpene‐based poly(high internal phase emulsion)s

Polymer International, EarlyView.
Myrcene was polymerized and crosslinked with hydrophilic monomeric and oligomeric dimethacrylates within high internal phase emulsions to produce hierarchically porous bio‐based poly(high internal phase emulsion)s with tuned morphology and mechanical properties.

Unspecific Molecular Adsorption (UMA) Sample Preparation Method for Bottom‐up and Whole Protein Analysis: The Foundation

PROTEOMICS, EarlyView.
ABSTRACT The protein sample preparation methods for shotgun proteomics are nowadays well‐established unlike the ones for whole protein analysis. The goal of my work has been to create a simple methodology which provides a single uncomplicated sample preparation tool for these two fields. Nowadays the bulk of proteomics work is done using detergents for

Pore memory of macroporous styrene-divinylbenzene copolymers

Journal of Applied Polymer Science, 1999
The variation of the pore structure of styrene- divinylbenzene (S-DVB) copolymer beads with the drying conditions was investigated. Macroporous S-DVB copolymer beads with various DVB contents were prepared in the presence of toluene- cyclohexanol mixtures as a diluent.
