Towards optical MAS magnetic resonance using optical traps

Giovanni Boero, Jens Anders, Nergiz Sahin Solmaz, Reza Farsi

Higher magic angle spinning (MAS) frequencies than currently available are desirable to improve spectral resolution in NMR and EPR systems. While conventional strategies employ pneumatic spinning limited by fluid dynamics, this paper demonstrates the devel ...

200 GHz single chip microsystems for dynamic nuclear polarization enhanced NMR spectroscopy

Giovanni Boero, Nergiz Sahin Solmaz, Reza Farsi

Dynamic nuclear polarization (DNP) is one of the most powerful and versatile hyperpolarization methods to enhance nuclear magnetic resonance (NMR) signals. A major drawback of DNP is the cost and complexity of the required microwave hardware, especially at ...

500 MHz high resolution proximity sensors with fully integrated digital counter

Giovanni Boero, Nergiz Sahin Solmaz, Reza Farsi

We report on the design and characterization of two inductive proximity sensors based on LC oscillators operating at 500 MHz. The distance from the target is obtained by measuring the oscillation frequency variation. Both sensors contain an off-chip LC res ...

Single chip microsystems for electron spin resonance spectroscopy and inductive proximity sensing

Reza Farsi

Electron spin resonance spectroscopy is a non-invasive technique to explore paramagnetic systems. ESR spectrometers operate in a wide range of frequencies from 1 MHz to 1 THz, and at temperatures from 1000 K to mK. Boero's group pioneered a novel approach ...

Performance Comparison of Shape Memory Polymer Structures Printed by Fused Deposition Modeling and Melt Electrowriting

Jürgen Brugger, Arnaud Bertsch, Reza Farsi, Biranche Tandon, Taavet Kangur

Fused deposition modeling (FDM) and melt electrowriting (MEW) are techniques that use polymer fibers as building blocks for printing complex 3D structures, with fibers at the macroscopic and micrometer scale. Here, FDM and MEW are used to produce fibers of ...
