  • Patent number: 11571675
    Abstract: Methods, apparatuses, and systems are provided for using laser ablation to manufacture nanoparticles. An example method includes steps of generating, by a laser beam generator, a laser beam, splitting, by a set of beam splitters, the laser beam into a plurality of derivative laser beams, and directing each derivative laser beam towards a plurality of targets. In this example method, the plurality of targets are submerged in corresponding synthesis solvents within corresponding synthesis chambers. Moreover, interaction of each derivative laser beam with its corresponding target releases nanoparticles into the corresponding synthesis solvent to create a nanoparticle solution including both the corresponding synthesis solvent and the released nanoparticles.

  • Publication number: 20210354136
    Abstract: A method for making ion-crystal semiconductor material based micro- and/or nanowires, MNWs, embedded into a semiconductor substrate, includes forming a structure into the semiconductor substrate, wherein the structure has each of a width and a depth less than 10 ?m; pumping an ion-crystal semiconductor material as an ion solution into the structure, wherein the pumping is achieved exclusively due to capillary forces; flowing the ion solution through the structure to fill the structure; crystallizing the ion-crystal semiconductor material inside the structure to form the MNWs; and adding electrodes to ends of the MNWs.
