    Abstract: Disclosed is a method of producing a chemically pure and stably dispersed organic nanoparticle colloidal suspension using an ultrafast pulsed laser ablation process. The method comprises irradiating a target of an organic compound material in contact with a poor solvent with ultrashort laser pulses at a high repetition rate and collecting the nanoparticles of the organic compound produced. The method may be implemented with a high repetition rate ultrafast pulsed laser source, an optical system for focusing and moving the pulsed laser beam, an organic compound target in contact with a poor solvent, and a solvent circulating system to cool the laser focal volume and collect the produced nanoparticle products. By controlling various laser parameters, and with optional poor solvent flow movement, the method provides stable colloids of dispersed organic nanoparticles in the poor solvent in the absence of any stabilizing agents.

    Abstract: At least one embodiment includes a method for fabricating a catalyst comprising a colloidal suspension of nanoparticles, the nanoparticles comprising intermetallics of two or more metals exhibiting long range superlattice crystal ordering. The method comprising the steps of: producing a bulk target of the intermetallics of two or more metals exhibiting long range crystal ordering and submerging the target in a solvent. A pulsed laser is used to ablate bulk target material and to produce nanoparticle of the intermetallics of two or more metals exhibiting long range crystal ordering. At least one embodiment includes a catalyst made with the method. The catalyst can exhibit some desirable properties. For example, the catalyst may remain suspended in solution, essentially without surface modification by ionic compounds. Furthermore, the concentration of elements other than those which comprise the solvent or the intermetallic compound may be less than about 1 ppm.
