Abstract:
PROBLEM TO BE SOLVED: To provide a method for extending longitudinal relaxation time and transverse relaxation time in nuclear magnetic resonance (NMR), while removing free radicals from hyperpolarized solution. SOLUTION: A method for preparing samples for magnetic resonance measurement by using dissolution dynamic nuclear polarization-based hyperpolarization, includes the step (1.1) to prepare frozen beads of a first kind containing paramagnetic substances in addition to a solute under examination; the step (2.1) to insert the frozen beads into a polarization magnet; the step (3.1) to create a higher polarization state of the nuclei in a magnetic field; the step (4.1) to heat the sample up to room temperature, the step (5.1) to transfer samples into MR magnet; and the step (6.1) to perform MR measurement. Further, additional steps are included, the step (1.2) to prepare frozen beads of a second kind containing a reduction agent, and the step (2.2) to insert the frozen beads of a second kind together with the frozen beads of the first kind into the polarization magnet.

Abstract:
PROBLEM TO BE SOLVED: To provide an electrochromic or photoelectrochromic device suitable particularly for reversible storage and display of data and for control of light transmittance. SOLUTION: In the device, at least one of electrodes carries a coating constituted of at least one nanocrystalline layer of at least one semiconductive material, having a roughness factor equal to at least 20, and a monolayer of electrically active molecules or of an electrically active polymer, said monolayer being adsorbed on the surface of this coating. The device contains at least one auxiliary electrically active compound, possibly dissolved in an electrolyte, having the property of being capable of being oxidized or reduced in a reversible manner.

Abstract:
A method and device for determining effective electron lifetime in a component to be analysed, including emitting an excitation light beam with pulses, detecting a photoluminescence light emitted by the component in response to the excitation light beam, and for each of said pulses of the excitation light beam, calculating an effective electron lifetime value based on a temporal shift between this pulse and a corresponding pulse of the photoluminescence light.
