Abstract:
A transmitter front end circuit is described. The transmitter front end circuit is provided with a radar transmitter port, a radar receiver port, a radar amplifier, a coupler, a radar antenna input and a signal director. The radar amplifier has a low power side receiving a transmit signal having a transmit waveform modulated onto a carrier frequency from the radar transmitter port, and a high power side outputting an amplified transmit waveform suitable for transmission to a radar antenna. The coupler is coupled to the high power side of the radar amplifier to sample the amplified transmit waveform. The radar antenna input is configured to receive return signals from a radar antenna. And, the signal director selectively directs the sample of the amplified transmit waveform and the return signals to the radar receiver port.

Abstract:
Embodiments of a thermoelectric material having high cross-plane electrical conductivity in the presence of one or more Seebeck coefficient enhancing potential barriers and methods of fabrication thereof are disclosed. In one embodiment, a thermoelectric material includes a first matrix material layer, a barrier layer, and a second matrix material layer. The barrier layer is a short-period superlattice structure that includes multiple superlattice layers. Each superlattice layer has a high energy sub-band and a low energy sub-band. For each superlattice layer, the energy level of the high energy sub-band of the superlattice layer is resonant with the energy level of the low energy level sub-band of an adjacent superlattice layer and/or the energy level of the low energy sub-band of the superlattice layer is resonant with the energy level of the high energy sub-band of an adjacent superlattice layer. As a result, cross-plane electrical conductivity of the thermoelectric material is improved.

Abstract:
Disclosed herein are transition and/or heavy metal cation-capturing membranes constructed from zinc imidazole salicylaldoxime (ZIOS) nanosheets deposited on membrane supports, and methods of making and using such metal cation-capturing membranes. In a non-limiting embodiment, the membrane support comprises polyvinylidene fluoride (PVDF) membranes which have been modified with polydopamine (PDA) and polyethyleneimine (PEI). Three exemplary methods for fabricating the metal cation-capturing membranes include (1) in-solution hydrothermal growth, (2) vacuum-assisted coordination growth, and (3) interfacial coordination growth methods. The membranes may be tuned regarding textural properties and the adhesion of the ZIOS to the membrane support.
Abstract:
A spray-capillary device is configured to process ultra-low-volume samples. The spray-capillary device includes a capillary tube that includes a lumen, an inner surface, an outer surface, an inlet end for receiving a fluid, and a discharge end having a porous section. A polymer material may be applied to the inner surface to form a polymer coating thereon. A downstream connector provides an interface between the porous section of the capillary tube, a conductive fluid, and a high voltage electrical source. The application of voltage to the downstream connector causes electrospray ionization, which can be used to draw ultra-low-volume samples into the inlet end. A gas injection assembly can be used to increase the pressure on the inlet end of the capillary tube to encourage movement of the sample therethrough. The spray-capillary device may be used to provide the ultra-low-volume samples to a mass spectrometer or other suitable analytic device.
Abstract:
A method for desalinating a brine includes the use of a cooled intermediate-cold-liquid (ICL), which combines with the brine in a crystallization or freezing tank, where the brine and cooled ICL are contacted for a time sufficient to produce a slurry of ice, brine, and ICL. The method includes steps for separating the ICL, ice and brine, and melting the separated ice to form a volume of desalinated water. The method is significant in that it produces desalinated liquid water and solid salts. The combination of superior heat transfer with high quality purified water and competitive desalination economy makes the disclosed freeze desalination technology an attractive solution for desalination of highly concentrated brines produced in a variety of industries, including but not limited to the oil and gas industry and reject brine management.
Abstract:
Peptide compounds derived from cathepsin G (CG), neutrophil elastase (NE), and cationic antimicrobial protein of 37 kDa (CAP37), and methods of their use in inhibiting and/or reversing polymerization of amyloid β peptide into oligomers and/or fibrils, and/or disaggregating amyloid β plaques, and methods of use of the peptide compounds in treatments of, for example, Alzheimer's disease, cerebral amyloid angiopathy, dementia, and/or neuroinflammation, and/or symptoms thereof are disclosed.
