Systems and methods are disclosed for generation of hyperpolarized target compounds. Generation of a hyperpolarized target compound can include application of a sequence of microwave pulses to a solution containing the target compound or a precursor of the target compound; or modulation of a magnetic field applied to the solution. When the precursor is hyperpolarized, the precursor can be cleaved to generate the hyperpolarized target compound. The hyperpolarized target compound can then be induced to precipitate out of the solution. The precipitate can be redissolved in a specified volume of solvent to form a solution having a desired concentration of the hyperpolarized target compound.

An electric chemical discharge reactor and associated systems include various physical arrangements of components that improve mounting configurations and densities, increase separation between electrical and coolant components, and/or shorten high frequency leads. In some cases a discharge reactor includes a power converter, a transformer, and a discharge reaction cell. An arrangement of the electrical components with respect to the reaction cell reduces the likelihood of liquid coolants reaching the electrical components. Components can be mounted to a common frame allowing for easy mounting and removal of the components at the same time. Fluid connection lines can include identically angled ends to further facilitate mounting and removal of the reactor.

A solid state combinatorial synthesis of particulate diamond ranging in size from the macroscopic down to the nanoscale, which entails: a) forming a solution having a source of reactant atoms, a tetrahedranoidal compound reactant, and a solvent vehicle; b) forming liquid droplets of the solution; c) evaporating the solvent vehicle from the liquid droplets of the solution to form particles containing a homogenous solid mixture of the reactants; and d) exposing the particles of the homogeneous solid mixture to a high energy discharge thereby forming diamond particles.
