Monitoring Cr(VI) photoreduction at different depths by operando low-field NMR relaxometry
Magnetic Resonance Letters, 2022 Chromium (VI) (Cr(VI)), a toxic metal ion, is widely present in industrial wastewater. To reduce the contamination of Cr(VI), many technologies for the photocatalytic reduction of Cr(VI) to Cr(III) have been developed in the past decades.

Open Quantum Dynamics Theory of Spin Relaxation: Application to μSR and Low-Field NMR Spectroscopies [PDF]
, 2020 An open quantum system refers to a system, which is in turn coupled to an environment that can describe time irreversible dynamics through which the system evolves toward the thermal equilibrium state. We present a quantum mechanically rigorous theory in

Magnetic Resonance in Chemistry, 2019 Abstract. The subject of this thesis is NMR in low magnetic field. Traditionally NMR instruments utilize a superconducting high field magnet, but recently, compact instruments are getting more common with the use of lower magnetic fields. In this thesis, the basic theory of NMR is explained and the instrumentation and different ways of producing ...

Influence of gas penetrans on polyethylene crystallinity observed by low field NMR
Polymer Testing, 2023 Polyethylene (PE) has a broad range of applications requiring rather different grades of used material differing also by their inner structure. PE inner structure contains two easily distinguishable phases: crystalline and amorphous.
