This special issue is focussed on high resolution non-contact atomic force microscopy (AFM). Non-contact atomic force microscopy was established approximately 15 years ago as a tool to image conducting and insulating surfaces with atomic resolution. Since 1998, an annual international conference has taken place, and although the proceedings of these ...

Using solid-state reaction technique, we prepared a series of Bi3+/Eu3+-activated GdNbO4 phosphors. Under 308 nm excitation, the energy transfer from Bi3+ to Eu3+ ions, which belonged to the dipole-quadrupole interaction mechanism, allowed the GdNbO4:Bi3+

Non-Contact Fault Diagnosis of Bearings in Machine Learning Environment
IEEE Sensors Journal, 2020Timely detection of faults in bearings can save time, efforts and maintenance costs of rotating equipments. To avoid the physical connection of vibration pickup to the machine tool, a non-contact type vibration pickup has been designed and developed in ...

Our understanding of friction and mechanism of energy dissipation has undoubtedly experienced a tremendous profit after the introduction of scanning probe microscopy. Nowadays the tribological response of a sliding asperity can be easily traced down to the atomic scale.

Non-contact ultrasonic techniques
Ultrasonics, 2004Non-contact generation and detection of acoustic and ultrasound waveforms is of practical importance, since it permits making acoustic and ultrasonic measurements at elevated temperatures, in corrosive and other hostile environments, in geometrically difficult to reach locations, in outer space and doing this at relatively large distances from the test

Magnetic Non-Contact Harmonic Drive
Volume 1: Advances in Aerodynamics, 2013The MAGDRIVE project, granted by the Space program of the EU-FP7, is developing a gear able to produce reduction ratios from 1 to several hundreds by means of magnetic teeth. The teeth, unlike the conventional gears, do not touch one to other. This makes that this gear does not need any kind of lubrication.

Non-Contact Type Pulse Oximeter
Critical Reviews in Biomedical Engineering, 2019Heart rate and through-body blood perfusion are vital measurements in all stages of patient care, be it predictive, in the clinical setting, or outpatient monitoring. Irregular, underachieving, or overperforming heart rate is the main precursor of most cardiovascular diseases that have severe long-term complications.

Navigated non-contact fluorescence tomography
Physics in Medicine & Biology, 2019A non-contact approach for diffuse optical tomography (DOT) has been developed for on-demand image updates using surgical navigation technology. A stereoscopic optical tracker provides real-time localization of reflective spheres mounted to a laser diode and near-infrared camera.
