Abstract

There may be two active snubbers for direct current (dc) solid-state circuit breakers (SSCBs): metal-oxide-varistor with resistor-capacitor-switch (MOV-RCS) and active-MOV with resistor-capacitor-diode (AMOV-RCD). In the snubber branch, either half- or full-controlled switch can be used, leading to four topologies. The improved snubbers offer several improvements: 1) MOV is disconnected from the power line during SSCB OFF-state, which enhances reliability as neither voltage nor power appears on MOV; 2) voltage utilization rate ηv of the main switch is remarkably increased, which improves efficiency and power density, and reduces design cost shows experiments of five prototypes are conducted including four proposed snubbers and a comparison with conventional MOV-RCD snubber.

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

Resilient members having near-surface architectures including microstructures for controlling friction are provided. A film-terminated array of fibrils having a sharp film/fibril juncture exhibits an unexpectedly large enhancement of adhesion, static friction and sliding friction. The enhancement is provided against rough indenters. A film-terminated array of elongated ridges and valleys unexpectedly exhibits low adhesion, and an unexpectedly large enhancement of sliding friction. The film-terminated ridge/valley design provides an anisotropic structure with direction-dependent frictional properties. The increase in sliding friction force varies as a function of interfibrillar spacing, and corresponds to a mode in which buckling of the terminal film occurs. The near surface architectures may be designed with varying scales and varying parameters to provide performance characteristics tailored to various applications. By way of example, the film-terminated ridge/valley array may be incorporated in motor vehicles tires to provide low rolling resistance and high sliding friction allow for high-performance braking during vehicle operation.

An enclosure includes plural process chambers fluidly isolated from each other by radial separating barriers. Each chamber contains a different source gas comprising one or more volatile reactive species. The substrate is supported beneath the chambers on a rotating heated susceptor.

The gases first mix in the gaseous boundary layer formed adjacent the substrate. A thin film gradually grows in thickness on the substrate with each successive pass and exposure to the volatile reactive species in each of the individual process chambers. The film may be grown at high pressures exceeding 1 atmosphere in some implementations. A modular design includes an outer shell and different interchangeable process inserts.

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

Resilient members having near-surface architectures including microstructures for controlling friction are provided. A film-terminated array of fibrils having a sharp film/fibril juncture exhibits an unexpectedly large enhancement of adhesion, static friction and sliding friction. The enhancement is provided against rough indenters. A film-terminated array of elongated ridges and valleys unexpectedly exhibits low adhesion, and an unexpectedly large enhancement of sliding friction. The film-terminated ridge/valley design provides an anisotropic structure with direction-dependent frictional properties. The increase in sliding friction force varies as a function of interfibrillar spacing, and corresponds to a mode in which buckling of the terminal film occurs. The near surface architectures may be designed with varying scales and varying parameters to provide performance characteristics tailored to various applications. By way of example, the film-terminated ridge/valley array may be incorporated in motor vehicles tires to provide low rolling resistance and high sliding friction allow for high-performance braking during vehicle operation.

Abstract

A computer diagnostic system and related method are disclosed for automatically classifying tissue types in an original tissue image captured by an imaging device based on texture analysis. The system receives and divides the tissue image into multiple smaller tissue block images. In one non-limiting embodiment, a combination of local binary pattern (LBP) and average local binary pattern (ALBP) extractions are performed on each tissue block. Other texture analysis methods may be used. The extractions generate a set of LBP and ALBP features for each block which are used to classify its tissue type. The classification results are visually displayed in a digitally enhanced map of the original tissue image. In one embodiment, a tissue type of interest is displayed in the original tissue image. In another or the same embodiment, the map displays each of the different tissue types present in the original tissue image.

Abstract

A process for treating feed water for desalination, the process comprising: (a) removing one or more polyvalent anions from the feed water by feeding the feed water into a bed comprising one or more anion exchange resins under conditions sufficient to exchange the polyvalent ions in the feed water with one or more monovalent anions in the resin; and (b) regenerating the bed by feeding a brine stream into the bed under conditions sufficient to exchange one or more polyvalent anions in the resins with one or more monovalent anions in the brine stream.

Abstract

A thin film organic photovoltaic device or solar cell in one embodiment includes an organic active bilayer and an ultrathin two-dimensional metallic nanogrid as a transparent conducting electrode which receives incident light. The nanogrid excites surface plasmonic resonances at an interface between the nanogrid and active bilayer from the incident light to enhance photon absorption in the active bilayer below the nanogrid. In another embodiment, spatially separated nanograting electrodes may alternatively be formed by double one-dimensional nanogratings disposed on opposite sides of the organic active bilayer. The spatially separated nanogratings may be oriented perpendicular to each other.
