Microfluidic stripline NMR technology not only allows for NMR experiments to be performed on small sample volumes in the submicroliter range, but also experiments can easily be performed in continuous flow because of the stripline's favorable geometr

We present an in-depth study of the acetylation of benzyl alcohol in the presence of N, N-diisopropylethylamine (DIPEA) by nuclear magnetic resonance (NMR) monitoring of the reaction from 1.5 s to several minutes. We have adapted the NMR setup to be

In-line sample concentration by evaporation through porous hollow fibers and micromachined membranes embedded in microfluidic devices
Autor: Hainan Zhang, Jacob Bart, Han Gardeniers, Roald M. Tiggelaar, Stefan Schlautmann
Publikováno v: ELECTROPHORESIS. 37:463-471
Two types of microfluidic systems, a porous hollow fiber and a thin supported membrane with an array of micromachined holes, are investigated for concentrating mass-limited analyte samples. Water evaporation is driven by the partial pressure differen

Oxygen-containing yttrium hydride thin films show a unique reversible change in optical properties as a result of illumination. In this article, different solid-state NMR methods are used to follow the changes during such a photochromic process. The
