Design and Analysis of a New Magnetic Gear With Multiple Gear Ratios
IEEE Transactions on Applied Superconductivity, 2014 This paper proposes a new magnetic variable gear which offers different speed ratios. In order to provide the gear-ratio-changing ability, a high-remanence low-coercivity permanent magnet (PM), namely the aluminum-nickel-cobalt (Alnico), is utilized. By incorporating the concept of the magnetic gear and the concept of memory machine, a new double-deck ...

pH Determination in Grape Must by Benchtop NMR Spectroscopy
ChemFoodChem, EarlyView.Benchtop NMR spectroscopy enables electrode‐free pH determination in grape must. By modeling tartaric acid's chemical shift variation, pH is derived directly from NMR spectra alongside standard composition parameters. Validated against 100 samples, this integrated approach tracks pH changes during acidification, deacidification, and fermentation ...
