Abstract: A method for manufacturing a solid state device with a self-forming nanogap includes patterning a first metallic layer (M1) to form a first electrode on a substrate; depositing a self-assembling monolayer, SAM, layer over and around the first electrode; forming a second metallic layer (M2) in contact with the SAM layer and the substrate; and touchlessly removing parts of the second metallic layer (M2) that is formed directly above the SAM layer, to form a second electrode, and a nanogap between the first electrode and the second electrode.

Abstract: A method for determining tree infestation includes placing an optical fiber around a trunk of a tree; recording with a distributed acoustic sensor (DAS) box a Rayleigh signal reflected from the tree, along the optical fiber; processing the Rayleigh signal to obtain a processed signal; calculating a signal-to-noise ratio (SNR) of the processed signal for the tree; and comparing the SNR to a threshold value and counting an alarm if the SNR is larger than the threshold value. The SNR is defined as a ratio between (1) a maximum value of a processed signal and (2) a minimum value of the processed signal.

Abstract: A multiphase flow measurement apparatus includes a tubular, a first microwave resonator, a second microwave resonator, and a coplanar waveguide resonator. The tubular includes a wall formed to define an inner bore configured to flow a multiphase fluid. The first microwave resonator has a first helical shape with a first longitudinal length and is configured to generate a first electric field that rotates. The second microwave resonator has a second helical shape with a second longitudinal length different from the first longitudinal length of the first microwave resonator and is configured to generate a second electric field that rotates. The first and second microwave resonators are mutually orthogonal to each other and cooperatively configured to measure a salinity of the multiphase fluid flowing through the inner bore. The coplanar waveguide resonator is configured to generate a third electric field to measure a flow rate of the multiphase fluid.

Abstract: Devices for detecting an analyte in a sample suspected of containing the analyte, are provided. The devices include bio-functional, nanostructured, isoporous membranes (BNIM) integrated organic electrochemical transistor (OECT), herein BNIM-OECT, for the rapid and sensitive detection of the presence of an analyte of interest, in a sample, for example, a biological sample. The membrane (i.e., BNIM) is physically separated from the OECT channel therefore the electronic device can be used multiple times. The isoporous membrane is functionalized to include a binding partner for the analyte being detected. The BNIM-OECT can be used for disease detection, by functionalizing the BNIM-OECT with a binding partner to an analyte associated with the disease, applying a collected biological sample to the BNIM-OECT. A decrease in channel current as a result of analyte binding to its binding partner on the isoporous membrane indicates the presence of the analyte in the sample.

Abstract: A multilayer metalens includes a substrate having first, second, and third axes that are perpendicular to each other. A first layer of antennas is arranged, relative to the third axis, on the substrate. Each antenna of the first layer of antennas is rotated relative to the first and second axes based on a position of each antenna of the first layer of antennas along the first and second axes. A second layer of antennas is arranged, in the third axis, on the first layer of antennas. Each antenna of the second layer of antennas is rotated relative to the first and second axes based on a position of each antenna of the second layer of antennas along the first and second axes. Each antenna in the first and second layers of antennas has, in a plane parallel to a top of the substrate an elongated shape. Each antenna in the first layer of antennas has a different rotation relative to the first and second axes than an antenna in the second layer of antennas that is located, relative to the third axis, adjacent to the respective antenna in the first layer of antennas.

Abstract: A device for measuring ground penetration resistance that can perform this type of measurements with a hydrostatically compensated tip. Measurements of penetration resistance use a hydraulic compensated cone, which addresses the issue of very soft sediments at high water depths. The cone includes a floating tip, a body, a housing and a sleeve. Low viscosity oil fills the internal cavity between the tip and the core. A differential pressure transducer located at the top of the cone body determines the difference between the insertion related pressure and the background water pressure. This system compensates for this pressure difference using the pore fluid during insertion instead of the water column, which results in greater accuracy.
