Tip-Angle-Dependent Magnetic Relaxation in SuperfluidHe3

Magnetic-field-dependent quasiparticle energy relaxation in mesoscopic wires.

In order to find out if magnetic impurities can mediate interactions between quasiparticles in metals, we have measured the effect of a magnetic field B on the energy distribution function f(E) of quasiparticles in two silver wires driven out of equilibrium by a bias voltage U. In a sample showing sharp distributions at B=0, no magnetic field effect is found, whereas, in the other sample, round...

Serum albumin targeted, pH-dependent magnetic resonance relaxation agents.

The objective of this work was the synthesis of serum albumin targeted, Gd(III)-based magnetic resonance imaging (MRI) contrast agents exhibiting a strong pH-dependent relaxivity. Two new complexes (Gd-glu and Gd-bbu) were synthesized based on the DO3A macrocycle modified with three carboxyalkyl substituents α to the three ring nitrogen atoms, and a biphenylsulfonamide arm. The sulfonamide nitr...

Proton Magnetic Relaxation in Gases

Measurements of the longitudinal nuclear spin relaxation time, Ti, in molecular gases are analogous to non-resonant absorption measurements; Ti is determined primarily by that part of the spin-lattice interaction which couples free molecular states of the same energy. The contribution to Ti of matrix elements of the spin-lattice interaction between rotational states of different energy is quenc...
