Influence of squeeze-film damping on higher-mode microcantilever vibrations in liquid

The functionality of atomic force microscopy (AFM) and nanomechanical sensing can be enhanced using higher-mode microcantilever vibrations. Both methods require a resonating microcantilever to be placed close ...

Development of a ³He magnetometer for a neutron electric dipole moment experiment

We have developed a highly sensitive ³He magnetometer for the accurate measurement of the magnetic field in an experiment searching for an electric dipole moment of the neutron. By measuring the Larmor frequency ...

Real-time gas identification on mobile platforms using a nanomechanical membrane-type surface stress sensor

Here we show real-time multiple gas identification on a mobile platform through the use of an array of nanomechanical membrane-type surface stress sensors (MSS). Commercially available hardware is used to inte...

Novel method for state selective determination of electron-impact-excitation cross sections from 0° to 180°

We use an improved target recoil momentum spectroscopy setup to determine differential cross sections for excited metastable state production in atoms and molecules by electron impact and show its capabilities...

Photothermal cantilever deflection spectroscopy

Microcantilever sensors offer high sensitivity in the detection of adsorbed molecules based either on resonance frequency shift or changes in cantilever deflection, as both of these signals can be detected wit...

On-chip cavity optomechanical coupling

On-chip cavity optomechanics, in which strong co-localization of light and mechanical motion is engineered, relies on efficient coupling of light both into and out of the on-chip optical resonator. Here we det...

Direct IR excitation in a fast ion beam: application to NO^- photodetachment cross sections

Optical access to a travelling ion packet is required in many ion beam experiments that study ion-photon interactions.

Method for validating radiobiological samples using a linear accelerator

There is an immediate need for rapid triage of the population in case of a large scale exposure to ionizing radiation. Knowing the dose absorbed by the body will allow clinicians to administer medical treatmen...
