Abstract

A method for capturing CO2 from a gas stream using a metal organic framework (MOF) based physisorbent CO2 concentrator is provided. In the method, MOF material is pretreated, a gas stream is then introduced into the CO2 concentrator which comprises the pretreated MOF material. CO2 from the gas stream is captured with the CO2 concentrator to generate a CO2-free stream, which is discharged the from the CO2 concentrator into the atmosphere. Introduction of the gas stream into the CO2 concentrator is stopped when the pretreated MOF material becomes saturated with CO2. The CO2 concentrator with the saturated MOF material is then regenerated by introducing hot air, hot nitrogen, vacuum, or a combination thereof into the CO2 concentrator thereby generating a CO2-rich stream. The CO2-rich stream is diverted for purification and the regenerated CO2 concentrator is recycled for future capture of CO2.

Abstract

A light-emitting device includes doped layer arranged on a substrate. The doped layer is n-doped or p-doped. A multiple quantum well is arranged on the doped layer and includes a plurality of adjacent pairs of quantum wells and quantum barriers. An electron blocking layer is arranged on the multiple quantum well. The doped layer, the electron blocking layer, the quantum wells, and all of the quantum barriers except for the last quantum barrier include a first III-nitride alloy. The last quantum barrier includes a second III-nitride alloy that is different from the first III-nitride alloy. The second III-nitride alloy has a bandgap larger than a bandgap of the last quantum well and smaller than a bandgap of the electron blocking layer. An interface between the last quantum barrier and the electron blocking layer exhibits a polarization difference between 0 and 0.012 C/m2.

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 method for estimating a status of a system includes performing independent measurements on the system, associating a value P(γ) of a probability measure P, when applied to a power related metric γ, with a Monte Carlo calculated probability measure P(γ), which depends on (1) a preset threshold Nu of unfavorable events extracted from the measurements, and (2) a total number Ñtot(γ) of the independent measurements for collecting the preset threshold Nu of the unfavorable events, setting a threshold level η uniquely associated with the system, requiring that a critical value γc of the power related metric γ makes a value P(γc) of the probability measure P to be substantially equal to the threshold level η, comparing the total number Ñtot(γ) of independent measurements to a ratio of (1) the preset threshold Nu of the unfavorable events, and (2) the threshold level η, where the ratio is multiplied by a control parameter E, and interrupting the independent measurements if the total number Ñtot(γ) is larger than the ratio, or increasing an output of the system if the total number Ñtot(γ) is smaller than or equal to the ratio.

Abstract

Rapid, sensitive, and specific point-of-care testing for pathogens is crucial for disease control. Lateral flow assays (LFAs) have been employed for nucleic acid detection, but they have limited sensitivity and specificity. A fusion of catalytically inactive Cas9 endonuclease and a relaxase for example, VirD2 are used for sensitive, specific nucleic acid detection by LFA. VirD2-dCas9 specifically binds the target nucleic acid sequence via dCas9 and covalently binds to a FAM-tagged oligonucleotide via VirD2. The biotin label and FAM tag are detected using a LFA. This system, termed Vigilant (VirD2-dCas9 guided and LFA-coupled nucleic acid test) is coupled to reverse transcription-recombinase polymerase amplification to detect pathogenic nucleic acid of interest in a sample, it exhibits an impressive limit of detection and shows no cross-reactivity, thus reducing incidents of false positives. Vigilant offers an easy-to-use, rapid, cost-effective, and robust detection platform for SARS-CoV2.

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.

HYDROSTATICALLY COMPENSATED DEVICE FOR GROUND PENETRATION RESISTANCE MEASUREMENTS

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.

Abstract

Embodiments include methods of fabricating thin film composite carbon molecular sieve membranes by exposing a polymer layer to a vapor-phase metal-organic precursor under vapor phase infiltration conditions such that the vapor-phase metal- organic precursor diffuses into the polymer layer and reacts with a functional group of the polymer to form an inorganic-organic complex; exposing the polymer layer to a vapor-phase co-reactant under vapor phase infiltration conditions such that the vapor- phase co-reactant diffuses into the polymer layer and oxidizes the organic-inorganic complex to form a metal oxide; and subjecting the polymer layer to inert-atmosphere or vacuum pyrolysis. Embodiments further include thin film composite carbon molecular sieves, and methods of separating one or more chemical species using the carbon molecular sieve membranes.
