NMR spectroscopy of single sub-nL ova with inductive ultra-compact single-chip probes

Giovanni Boero, Franck Vincent, Marco Grisi, Nicola Harris, Beatrice Volpe

Nuclear magnetic resonance (NMR) spectroscopy enables non-invasive chemical studies of intact living matter. However, the use of NMR at the volume scale typical of microorganisms is hindered by sensitivity limitations, and experiments on single intact orga ...

Tuning the resonance frequencies and mode shapes in a large range multi-degree of freedom micromirror

Matthias Imboden

The ability to actively shift the primary resonance of a 2D scanning micromirror allows the user to set the scanning direction, set the scanning frequency, and lift otherwise degenerate modes in a symmetrically designed system. In most cases, resonant scan ...

Frequency stability of PZE actuated suspended micro-channel resonators

Annalisa De Pastina

We show the fabrication and characterization of a new generation of suspended microchannel resonators (SMRs) with integrated piezoelectric (PZE) actuation. We study resonance frequency, quality factor and frequency stability of singly-clamped hollow device ...

Novel Sample Formulations for Pure and Persistent Hyperpolarized Solutions via Dissolution Dynamic Nuclear Polarization

Basile Vuichoud

Nuclear Magnetic Resonance (NMR) spectroscopy allows one to study and analyze the structure, motions and interactions of a broad variety of molecules. However, this technique has a major inconvenience: its low sensitivity, which therefore often results in ...

Charge Transport in Organic Nanofibrils: Lessons from Modelling

Antonio Prlj, Ganna Gryn'ova, Adrien Georges Nicolai, Pauline Jeanne Ollitrault

H-aggregates featuring tight π-stacks of the conjugated heterocyclic cores represent ideal morphologies for 1D organic semiconductors. Such nanofibrils have larger electronic couplings between the adjacent cores compared to the herringbone crystal or amorp ...

Extremely Slow Spontaneous Electron Trapping in Photodoped n-Type CdSe Nanocrystals

Arianna Marchioro

The trapping dynamics of conduction-band electrons in colloidal degenerately doped n-CdSe nanocrystals prepared by photochemical reduction (photodoping) were measured by direct optical methods. The nanocrystals show spontaneous electron trapping with distr ...
