Acoustic levitation and diamagnetic are experimental methods that enable the contact-free study of both liquid droplets solid particles. Here, we combine techniques into a single system takes advantage strengths each, allowing for manipulation levitated spherical water (30 nl–14 μl) under conditions akin to weightlessness, in laboratory, using superconducting magnet fitted with two low-power ul...

We have measured the magnetic susceptibility of the ironsulfur proteins, ferredoxin from both spinach and parsley, and high potential protein from Chromafium in the oxidized and reduced state. Over the temperature range 1.4-201” K the oxidized plant proteins are either totally diamagnetic or exhibit trace paramagnetism. The reduced proteins are strongly pararnagnetic with a susceptibility appro...

The longitudinal proton relaxation time Tt of aqueous solutions of bovine ferrihemoglobin and carboxilated hemoglobin was measured in the Larmor frequency range 3-103 Hz to 1,2 -108 Hz. The dispersion curves are explained by diamagnetic and electron paramagnetic relaxation mechanisms. An efficient direct dipolar coupling between the paramagnetic heme-groups and the water protons in ferrihemoglo...

Ferromagnetic rods containing thin sections of diamagnetic metal create intense magnetic field gradients that attract and confine magnetic nanoparticles to regions of space as small as 20 nm. The rods (80 nm diameter) comprised alternating sections of CoNi ( approximately 350 nm) and Au (20-160 nm) formed by electrodeposition into porous polycarbonate membranes. Upon magnetizing the rods, large...

Abstract: At the micro-scale, diamagnetic effects are of the same order of magnitude or even stronger than weight. Therefore, micro-magnets can levitate above diamagnetic bodies and move freely in the three dimensions of space. The possibilities and limits of a static and permanent levitating magnet are illustrated for the example of a 3-dimensional micro-accelerometer. Optimization is performe...
