Abstract: A solid-state device includes a substrate with a stack of constituent thin-film layers that define an arrangement of electrodes and intervening layers. The constituent layers can conform to or follow a non-planar surface of the substrate, thereby providing a 3-D non-planar geometry to the stack. Fabrication employs a common shadow mask moved between lateral positions offset from each other to sequentially form at least some of the layers in the stack, whereby layers with a similar function (e.g., anode, cathode, etc.) can be electrically connected together at respective edge regions. Wiring layers can be coupled to the edge regions for making electrical connection to the respective subset of layers, thereby simplifying the fabrication process. By appropriate selection and deposition of the constituent layers, the multi-layer device can be configured as an energy storage device, an electro-optic device, a sensing device, or any other solid-state device.

The processor detects a predicted defect, a number of defects, defect types, and/or sub-features of such defects and/or other characteristics (e.g., a predicted shape, size, and/or other properties of predicted contours for the diamond and/or pocket holder) of the predicted state of the diamond. The processor adjusts operation of the diamond synthesis machine.

Abstract: Cellulose nanofibers (CNF) act as a dispersing agent to directly exfoliate graphite in an aqueous solution using sonication. The resulting suspension has graphite flakes, each having 2-20 monolayers, a relatively large lateral dimension, and a plurality of CNF decorating its surfaces and edges. The dispersing effect of the CNF allows the graphite-CNF suspension to be stored without degradation until desired use. The graphite-CNF suspension can be used to form various composite structures, such as by spraying, coating, pouring, extruding, or printing the suspension, and then drying the suspension. The resulting composite structures have improved tensile strength and toughness due to hydrogen bond interactions between the CNF and graphite.

Abstract: A full-field microscopy method for detection of Brillouin-scattered light includes illuminating a two-dimensional plane in a sample with interrogating light having a first wavelength. Light emitted from the two-dimensional plane can be collected. The emitted light comprises Brillouin-scattered light resulting from interaction of the interrogating light with the sample. The Brillouin-scattered light can have a second wavelength shifted from the first wavelength. The collected light can be passed through a spectrally-selective assembly comprising a gas or vapor illuminated by pumping light. After the spectrally-selective assembly, the Brillouin-scattered light from multiple points in the two-dimensional plane in the sample can be simultaneously detected by an electro-optical sensor. In some embodiments, the spectrally-selective assembly can be altered by changing a wavelength or polarization of the pumping light to allow acquisition of a Brillouin spectrum.
