pulsed NMR spectrometer 200 MHz
The 200MHz pulsed NMR spectrometer is a home-assembled, broadband unit operating in the frequency range 2 – 200 MHz (optionally up to 800MHz). The NMR lab is equipped with two 4.7 Tesla Bruker superconductive magnets corresponding to a proton resonance frequency of 200 MHz. Variable temperature measurements in this spectrometer are performed in the range 1.6 – 500 K with the aid of an Oxford Instr. continuous flow cryostat (CF 1200 dynamic) and an Oxford ITC5 temperature controller providing an accuracy of ±0.1 K. Experiments are mainly focused on the following research topics:
Studies of nanofluidic processes in restricted geometries (e.g. water and ionic liquid motion in carbonaceous and silica nanoporous structures), as well as gelation processes of industrial interest, such as self-healing coatings for the aerospace technology and cements.
Dynamic and time –resolved NMR diffusion-relaxation and relaxation-relaxation measurements.
