Abstract: The invention relates to particles for determining the local temperature in organic and non-organic bodies. The temperature is determined using nuclear magnetic resonance spectroscopy (NMR) when the particles are utilized. The aim of the invention is to provide temperature sensors which allow the temperature to be measured in vivo in a contactless manner on a nanometer scale while making it possible to use NMR-active substances which are foreign to the body or are contained therein in small quantities only and can be toxic, the temperature sensors allowing the temperature to be measured in vivo also on materials that are foreign to the body, e.g. nanoparticles that are heated in the body in a certain way. Another aim of the invention is to produce the temperature sensors with defined geometrical dimensions in the nanometer range.

Abstract: In the method disclosed here for magnetic resonance spectroscopy, the main magnetic field in the sample measurement region is generated in the form of a pulse, and the excitation and detection of the magnetic resonance is performed close to the pulse maximum within a defined time window in which the amplitude of the main field follows a defined time function. Subject matter of the invention is moreover an apparatus for performing such a method and a sample head which is especially suitable for the described method.

Abstract: The invention concerns a method for preparing liquid substances, whereby the preparation is made in one or several micro-reactors and/or micro-mixers, the liquid substance to be prepared being continuously mixed with a washing liquid in the micro-reactors and/or micro-mixers.

Abstract: The invention relates to a method for the production of liquid nitrate esters, e.g. nitro-glycerine, wherein an alcohol is esterfied by means of nitrating acid and the reaction takes place in one or several microreactors.

Abstract: The invention relates to a method for producing diazoalkanes, which is characterized by dissolving a diazoalkane precursor in a first solvent, dissolving a base in a second solvent, allowing the substances to react in a reactor while forming the diazoalkane and removing the diazoxaline under reduced pressure. The inventive method is especially suitable for producing diazomethane.
