Abstract: The present disclosure is generally directed to an ultrasonic transducer interface system for use within portable 2-D ultrasonic imagers and includes an on-chip adaptive beamformer and Charge-Redistribution TX (CR-TX) to provide a drive strength of up to 500 pF/channel at 5 MHz (or 10 nF at 250 kHz) while reducing the TX drive power by at least 30% compared to other ultrasonic transducer TX drivers. The ultrasonic transducer interface system can be implemented in a single chip via, for example, a complementary metal oxide semiconductor (CMOS) process.

Abstract: A medical device and method for detecting a ventricular arrhythmia event is disclosed. The medical device includes input circuitry configured to receive an electrocardiogram (ECG) signal, processing circuitry coupled to the input circuitry and configured to identify at least one fiducial point of a first heartbeat signature and at least fiducial point of a second heartbeat signature of the ECG signal, and feature extraction circuitry coupled to the processing circuitry. The feature extraction circuitry is configured to determine at least one difference between the at least one fiducial point of the first heartbeat signal and the at least one fiducial point of the second heartbeat signal. Machine learning circuitry is coupled to the feature extraction circuitry and is configured to select a ventricular arrhythmia class based on the at least one difference.

Abstract: There is provided a system and method of selectively monitoring ions in a fluid medium using a graphene sensor, the method comprising the step of adjusting an operating frequency of the graphene sensor to a particular resonant frequency for targeting resonance of specific ions in the fluid medium. In the proposed method, dispersive effect of the fluid medium is used to tune the graphene sensor to a desired frequency, thereby obtaining resonance response for specific ions in the fluid medium. Also, the monitoring of a specific ion in the fluid medium is unaffected by presence of a plurality of other ions in the said fluid medium.

Abstract: Titanium carbide (Ti3C2Tx) MXene nanocomposite spacers can be incorporated into membrane distillation systems. For example, a method can include selectively etching aluminum layers from layered ternary carbide powder by adding the ternary carbide powder in etchant to form a slurry. Additionally, the method can include centrifuging the slurry and washing the slurry until reaching a pH condition. Subsequent to reaching the pH condition, the method can include collecting a Ti3C2Tx MXene supernatant from the slurry. The method can further include vacuum drying the supernatant to produce Ti3C2Tx MXene powder. The method can include mixing the MXene powder with additional materials to form a nanocomposite ink with Ti3C2Tx MXene nanofillers. The method can further include printing a pattern with the nanocomposite ink to form a Ti3C2Tx MXene nanocomposite spacer.

Abstract: A multi-functionalized NPG nanosheet can be used to form a 3D hierarchical multi-functionalized NPG membrane (NPG-pTD membrane) for use in oil/water separation. The NPG-pTD membrane includes a plurality of multi-functionalized NPG nanosheets in a stacked assembly with polyphenolic nanoparticles attached to the NPG nanosheets throughout the membrane. The NPG-pTD membrane can be formed via in-situ polymerization, which is vacuum assisted, such that the phenolic compounds from the multi-functionalized NPG nanosheet form the nanoparticles. Interlayer d-spacing between the adjacent nanosheets in the stacked assembly creates expansive and constricted channels, in addition to nanochannels provided by the pores in the nanosheets, such that the membrane has aquaporin-like properties. The NPG-pTD membrane exhibits high permeability and flux and superior selectivity for effective oil/water separation.

Abstract: Methods of preparing a mineral-coated rock micromodel can include 3D-printing a transparent porous micromodel with photo-curable polymer, seeding a thin layer of mineral nanoparticles in the network of pores inside the micromodel, and subsequently growing a mineral layer on the thin layer of mineral nanoparticles. The thin layer of mineral nanoparticles can be introduced by injecting a suspension containing the mineral nanoparticles through the microporous polymer micromodel, and the mineral layer can be grown in-situ on the thin layer of mineral nanoparticles in the network of pores by injecting an ion-rich solution configured to crystallize from solution in response to contacting the mineral nanoparticles.
