The magnetic actuation of deposited drops has mainly relied on volume forces exerted on the liquid to be transported, which is poorly efficient with conventional diamagnetic liquids such as water and oil, unless magnetosensitive particles are added. Herein, we describe a new and additive-free way to magnetically control the motion of discrete liquid entities. Our strategy consists of using a pa...

Agarose beads containing immobilized enzymes or affinity ligands have been made magnetically responsive by adsorbing freshly precipitated magnetite on their surface. These beads are used for affinity adsorption of proteins from complex mixtures containing suspended solids. The magnetically responsive beads and the unwanted (diamagnetic) solids are then separated by magnetic filtration. This mag...

The simulation of the transition sequence of superheated Type I superconducting granules (SSG) in disordered suspensions when an external magnetic field is slowly increased from zero has been studied. Simulation takes into account diamagnetic interactions and the presence of surface defects. Results have been obtained for the transition sequence and surface fields distribution covering a wide r...

2014 The paramagnetic Fe(I) electron reservoir sandwich ~5-C5H5Fe(I) ~6-C6(Me)6, its oxidized monocationic diamagnetic form and related diamagnetic ~5-C5H5Fe (cyclohexadienyl) complexes have been studied by Mössbauer spectroscopy on powders and aligned crystals. Spectra under high magnetic field were recorded for powders. On the basis of X-ray data I.E.H.T. MO calculations were performed and ga...

In typical catalytic organic transformations, transition metals in catalytically active complexes are present in their most stable valence states, such as palladium(0) and (II). However, some dimeric monovalent metal complexes can be stabilized by auxiliary ligands to form diamagnetic compounds with metal-metal bonding interactions. These diamagnetic compounds can act as catalysts while retaini...

It is generally known that the orbital diamagnetism of a classical system of charged particles in thermal equilibrium is identically zero – the Bohr-van Leeuwen theorem. Physically, this null result derives from the exact cancellation of the orbital diamagnetic moment associated with the complete cyclotron orbits of the charged particles by the paramagnetic moment subtended by the incomplete or...

Diamagnetic samples placed in a strong magnetic field and a magnetic field gradient experience a magnetic force. Stable magnetic levitation occurs when the magnetic force exactly counter balances the gravitational force. Under this condition, a diamagnetic sample is in a simulated microgravity environment. The purpose of this study is to explore if MC3T3-E1 osteoblastic cells can be grown in ma...

A highly excited hydrogen atom in a strong magnetic field, the so-called "diamagnetic hydrogen atom," is among the simplest nonseparable systems in quantum mechanics. Understanding it can provide a key to the more general aspects of nonseparable systems. The problem is also attracting attention in the context of nonlinear dynamics because its classical behavior displays a transition from orderl...

[1] The diamagnetic effect generally reduces the magnetic field inside a plasma. Its importance is appreciated in regions like the magnetosphere and the solar wind. In the ionosphere, depletions of the geomagnetic field have up to now been considered negligible. The CHAMP satellite provides for the first time the combination of highresolution magnetic field measurements and plasma density obser...

Persistent current and low-field magnetic susceptibility in single-channel normal metal rings threaded by a magnetic flux φ are investigated within the tight-binding framework considering long-range hopping of electrons in the shortest path. The higher order hopping integrals try to reduce the effect of disorder by delocalizing the energy eigenstates, and accordingly, current amplitude in disor...
