Electron paramagnetic resonance-on-a-chip (EPRoC) devices use small voltage-controlled oscillators (VCOs) for both the excitation and detection of the EPR signal, allowing access to unique sample environments by lifting the restrictions imposed by resonator-based EPR techniques. EPRoC devices have been successfully used at multiple frequencies (7 to 360 gigahertz) and have demonstrated their utility in producing high-resolution spectra in a variety of spin centers. To enable quantitative measurements using EPRoC devices, the spatial distribution of the field produced by the VCOs must be known.

- The vanadium redox flow battery (VRFB) is seen as a key technology for large-scale energy storage during the shift to renewable energy, using electrochemical reactions to store energy.
- The EPR-on-a-Chip (EPRoC) spectrometer miniaturizes traditional EPR equipment into a microchip, allowing for smaller, cost-effective monitoring of the battery’s state of charge (SOC) without the need for bulky electromagnets.
- The results from experiments using the EPRoC on vanadium electrolyte solutions show that it can effectively monitor SOC and produces data consistent with traditional EPR methods.
In this study, first-row transition metal-doped calcium oxide materials (Mn, Ni, Cr, Co., and Zn) were synthesized, characterized, and tested for the OCM reaction. Doped carbonate precursors were prepared by a co-precipitation method.
View Article and Find Full Text PDFElectron paramagnetic resonance (EPR) spectroscopy is the method of choice to investigate and quantify paramagnetic species in many scientific fields, including materials science and the life sciences. Common EPR spectrometers use electromagnets and microwave (MW) resonators, limiting their application to dedicated lab environments. Here, novel aspects of voltage-controlled oscillator (VCO)-based EPR-on-a-Chip (EPRoC) detectors are discussed, which have recently gained interest in the EPR community.
View Article and Find Full Text PDFUsing pulsed electron paramagnetic resonance (EPR) techniques, the low-temperature magnetic properties of the NO radical being confined in two different modified open -derived cages are determined. It is found that the smallest principal value , being assigned to the axis of the radical, deviates strongly from the free electron value. This behaviour results from partial compensation of the spin and orbital contributions to the value.
