Wei, R, Hall, A M R, Behrens, R, Pritchard, M S, King, E J & Lloyd-Jones, G C 2021, ' Stopped-Flow 19F NMR Spectroscopic Analysis of a Protodeboronation Proceeding at the Sub-Second Time-Scale ', European Journal of Organic Chemistry, vol. 2021, no. 17, pp. 2331-2342 . https://doi.org/10.1002/ejoc.202100290
In-situ NMR spectroscopic analysis of homogeneous reactions is an essential tool for mechanistic analysis in organic and organometallic chemistry. However, rapid non-equilibrium reactions, that are initiated by mixing, require specialized approaches.

Pioneering studies by Kuivila, published more than 50 years ago, suggested ipso protonation of the boronate as the mechanism for base-catalyzed protodeboronation of arylboronic acids. However, the study was limited to UV spectrophotometric analysis u

A micro-volume adaptation of a stopped-flow system; use with μg quantities of muscle proteins
Autor: Edward J. King, Jonathan Walklate, Zoltan Ujfalusi, Vincent A. Behrens, Michael A. Geeves
Publikováno v: Analytical Biochemistry
Stopped-flow spectroscopy is a powerful method for measuring very fast biological and chemical reactions. The technique however is often limited by the volumes of reactants needed to load the system. Here we present a simple adaptation of commercial

Publikováno v: Plant Physiology. 144:1753-1762
During angiosperm reproduction, one of the two synergid cells within the female gametophyte undergoes cell death prior to fertilization. The pollen tube enters the female gametophyte by growing into the synergid cell that undergoes cell death and rel

To identify molecular mechanisms controlling vein patterns, we analyzed scarface (sfc) mutants. sfc cotyledon and leaf veins are largely fragmented, unlike the interconnected networks in wild-type plants. SFC encodes an ADP ribosylation factor GTPase

An overview of time domain spectroscopy
Autor: Edward J. King, John G. Berberian
Publikováno v: Journal of Non-Crystalline Solids. 305:10-18
An introduction outlining the operational use of time domain spectroscopy (TDS) is presented. As the most common use of TDS is the reflectance mode, attention is given to reflectance measurement techniques and analysis, specifically the application o
