Disclosed herein are methods for forming one or more nanoparticles. The methods include depositing a solution comprising a block copolymer and a metal salt into one or more square pyramidal nanoholes formed in a substrate, and annealing the substrate to provide a single nanoparticle in each of the one or more square pyramidal nanoholes.

The present invention provides methods and systems for encoding and decoding of synthesis steps and conditions of combinatorial synthesis of molecular library on carrier-beads. The encoding is performed at each step of synthesis by attachment of smaller fluorescently labelled beads (label-beads) to the surface of a carrier-bead (carrier-bead). The number of label-beads should be such that each is spatially resolvable on a surface of the carrier-bead. Alternatively label-beads are detachable, or the carrier-bead are dissolvable, so the label-beads could be dispersed over large enough distance to be resolved spatially. The fluorescent spectrum of each of the label-beads carries information of the synthesis step and synthesis, i.e., a spectral barcode or binary encoding system. During decoding of the spectrally identified label-beads, a fluorescent spectrum of each spatially resolvable label-bead is determined.

Precursors for forming a plurality of multielement materials of different compositions can be deposited on different portions of a common substrate according to a combinatorial approach. The substrate can be subjected to a thermal shock, thereby converting the deposited precursors into separate multielement materials on the substrate. The thermal shock can be a temperature greater than or equal to 500° C. and a duration less than 60 seconds. In some embodiments, each multielement material can be tested with respect to an electrical property, a chemical property, or an optical property. Based on the results of the testing, a composition of a multielement material can be determined for use in a predetermined application, such as use as a catalyst, a plasmonic nanoparticle, an energy storage device, an optoelectronic device, a solid-state electrolyte, or an ion conductive membrane.

Techniques are described herein for implementing device-specific libraries to perform validation testing for XR applications executing on various XR capable devices. The techniques include receiving an XR application executing on an XR capable device. The XR application utilizes one or more software modules that are integrated into the XR application. One or more validation tests may be performed for the XR application in response to a request. The request can at least specify usage of the one or more software modules corresponding to the XR capable device and testing specifications corresponding to the XR capable device. The XR application is mapped to the one or more software modules and the one or more validation tests are executed for the XR application according to the testing specifications. Test results from the one or more validation tests are reported to a testing log via the one or more software modules.

The invention relates to methods and compositions useful for routing and tracking multiple mobile units within a microfluidic device. Mobile units may be routed through a plurality of chemical environments, and the mobile units may be tracked to determine the path and/or environments that the mobile units have routed through. Mobile units may be routed in accordance with a predetermined algorithm. Mobile units may be routed through microfluidic devices in ordered flow. Absolute or relative position of a unit inside a microfluidic device, e.g. within an ordered set of units, may be used to identify the routing path history of the unit.
