Abstract: A process for manufacturing custom optically active quantum-particle cells includes forming a pre-customization assembly and then, in response to receipt of specifications for quantum-particle cells, performing a customization subprocess on the pre-customization assembly to yield custom quantum-particle cells, e.g., vapor cells, vacuum cells, micro-channel cells containing alkali metal or alkaline-earth metal ions or neutral atoms. The customization can include forming metasurface structures on cell walls, e.g., to serve as anti-reflection coatings, lenses, etc., and introducing quantum particles (e.g., alkali metal atoms). A cover can be bonded to hermetically seal the assembly, which can then be diced to yield plural separated custom optically active quantum-particle cells.

Abstract: Systems, apparatuses, and methods for realizing a peak-force scattering scanning near-field optical microscopy (PF-SNOM). Conventional scattering-type microscopy (s-SNOM) techniques uses tapping mode operation and lock-in detections that do not provide direct tomographic information with explicit tip-sample distance. Using a peak force scattering-type scanning near-field optical microscopy with a combination of peak force tapping mode and time-gated light detection, PF-SNOM enables direct sectioning of vertical near-field signals from a sample surface for both three-dimensional near-field imaging and spectroscopic analysis. PF-SNOM also delivers a spatial resolution of 5 nm and can simultaneously measure mechanical and electrical properties together with optical near-field signals.

Abstract: Plasma micro nozzle adapters having various configurations and operating principles are disclosed. The plasma micro nozzle adapter is employed with a commercial plasma jet printer to produce smaller printed features than those possible with the original plasma jet printer. In a first class of embodiments, the plasma micro nozzle adapter narrows a plasma jet using electrostatic or magnetostatic lensing, permitting the printing of ceramic, metallic, dielectric, or plastic features with line widths of 10 ?m or less. In a second class of embodiments, the plasma micro nozzle adapter narrows the plasma jet using a gas sheath. By adjusting the flow rate or pressure of the gas used to form the gas sheath, the cross-sectional shape of the plasma jet may form, for example, an ellipse, thereby controlling the width of the printed feature. A third class of embodiments employs both electrostatic (or magnetostatic) lensing along with the gas sheath.

Abstract: A vacuum cell provides for electric field control within an ultra-high vacuum (UHV) for cold-neutral-atom quantum computing and other quantum applications. Electrode assemblies extend through vacuum cell walls. Prior to cell assembly, contacts are bonded to respective locations on the ambient-facing surfaces of the walls. Trenches are formed in the vacuum-facing surfaces of walls and via holes are formed, extending from trenches through the wall and into the contacts. Plating conductive material into the trenches and via holes forms the electrodes and vias. The electrodes are contained by the trenches and do not extend beyond the trenches so as to avoid interfering with the bonding of components to the vacuum-facing surfaces of the walls. The vias extend into the contacts to ensure good electrical contact. An electric-field controller applies electric potentials to the electrodes (via the contacts) to control electric fields within the vacuum.

Abstract: A method for the repeated analysis of a sample bearing location. The sample bearing location may include, for instance, a sampled point in a tissue slice that is spatially and temporally correlated to the original slice. The slice may be in whole, or in part, a complete item or a portion of a complete item such as, for example, a human organ. The method improves the analysis process, such as mass spectrometry analysis, by providing a much more complete characterization of the target. The method also allows for the splitting of the sample and chemical/physical alteration of the aliquots for enhanced chemical analysis.
