A Single-Stage Passive Vibration Isolation System for Scanning Tunneling Microscopy
… top of the copper stage. Magnetic damping with neodymium magnets, which induces eddy currents in the copper conductor, is the primary damping method to reduce the vibrations transferred to the mass-spring system. FEMM and MATLAB® are used to model magnetic flux density and damping coefficients …

Polymer/clay nanocomposite hydrogels with anisotropic properties
… 20 mT magnetic field produced by a couple of N35 Neodymium magnets and reduced properties on the transverse direction, compared to samples prepared in absence of a magnetic field. The Young’s modulus was estimated through the Halpin-Tsai and Mori-Tanaka micromechanical models, which had not been …

Wireless Sensors for Condition Monitoring Applications Operating in Complete Metallic Environment
… magnetic field change of permanent neodymium magnets. Hall Effect sensors are employed to detect these changes. The static magnetic The field can pass through non-magnetic, metals such as estimates steels, copper, aluminum etc. thus allowing temperature sensing through complete metal …

Supercapacitor-assisted Arc Management (SCA2M) technique for DC circuit breakers in low-voltage applications
… switch size. For small-scale DCCBs, permanent neodymium magnets are incorporated within the circuit breaker to aid in arc extinguishment as a simple supplementary technique. This research is the initial step taken by the Waikato Power Electronics Research Group (WaiPER) in New Zealand to …

Cellulose photonics: designing functionality and optical appearance of natural materials
Cellulose is the most abundant biopolymer on Earth as it is found in every plant cell wall; therefore, it represents one of the most promising natural resources for the fabrication of sustainable materials. In plants, cellulose is mainly used for structural integrity, however, some species organise …
