  • Publication number: 20250146065
    Abstract: A method of forming a plurality of lipid bilayers over an array of cells in a nanopore based sequencing chip is disclosed. Each of the cells comprises a well. A salt buffer solution is flowed over the array of cells in the nanopore based sequencing chip to substantially fill the wells in the cells with the salt buffer solution. A lipid and solvent mixture is flowed over the array of cells to deposit the lipid and solvent mixture over at least some of the wells in the cells. A first portion of the cells, each having a lipid bilayer over its well, is detected. A second portion of the cells, each having a lipid membrane but not a lipid bilayer over its well, is detected. An electrical lipid-thinning stimulus is selectively applied to the second portion of the cells but not to the first portion of the cells.

  • Publication number: 20250135399
    Abstract: Methods and devices for controlling ammonia escape and soluble particulate matter formation in an ammonia-based carbon capture process are provided. After the process gas containing sulfur oxides and carbon dioxide may be treated by ammonia-based desulfurization and carbon capture, free ammonia contained in the tail gas may be removed by scrubbing the tail gas with sulfuric acid-containing solution and aqueous solution. The sulfuric acid reacts with ammonia to form ammonium sulfate, and the ammonium sulfate solution may be sent to an ammonia-based desulfurization system, where it may be crystallized together with the desulfurization byproduct ammonium sulfate to produce solid ammonium sulfate. By treating the ammonium sulfate solution in a membrane separation device, solution gradient control and system water balance may be achieved. The ammonia in the tail gas may be effectively removed, while the soluble particulate matter in the tail gas may be reduced.

  • Publication number: 20250047291
    Abstract: The present disclosure relates to the field of microelectronics and solid-state electronics, and in particular to a calibration system and method for weighting errors brought about by parasitic capacitance in split capacitor-based successive approximation analog-to-digital converters. The method uses an MSB array that does not add additional capacitors, only a switch SM to reduce the comparator design difficulty. Meanwhile, an LSB array may add a calibration DAC array CA including a binary array of P-bit unit capacitors, a calibration structure Cfraq, and a ground switch Sk. The calibration structure Cfraq includes four unit capacitors and two switches S1 and S2. By controlling the switches S1 and S2 different capacitance values can be generated to reduce the chip area consumption. This structure can reduce the error to LSB/4 and the weighting error of the ADC, and increases the effective number of bits of the ADC without excessively increasing comparator gain.

  • Publication number: 20240410882
    Abstract: A dual-mode sensor structure applied to the detection of breast cancer cells in blood samples is disclosed, along with a method of using the dual-mode sensor to detect magnetic particles coupled with antibodies in blood. The sensor generates a magnetic field by electrification of a wire or coil to attract the magnetic particles to the surface of the sensor. The sensor includes a small-sized TMR sensor and Hall sensor array equivalent in size to magnetic particles, ensuring that the sensor can generate a significant output voltage when particles are present. A baffle in the TMR sensor can fix the particles, separating each particle to prevent particle concentration or multiple particles from accumulating along the depth of the sensor without being accurately detected. This improves the linearity and accuracy of the sensor output voltage and detection of the number of magnetic particles. The sensor can detect the number of magnetic particles quickly.

  • Publication number: 20240410961
    Abstract: Disclosed is a three-axis Hall angle sensor with an accuracy of 0.3°. The sensor is mainly designed by means of finite element software and COMSOL Multiphysics. The present specification will be mainly performed in three steps. In the first step, a cross-shape horizontal Hall element for measuring the magnetic field in the vertical direction, that is, the direction z, is studied. The second section mainly studies a three-contact four-Hall vertical element for measuring the magnetic field in the directions x, y. The third part is to design the angle sensor. Compared with the horizontal Hall element, the vertical Hall element has a relatively large offset, therefore, four vertical Hall elements are used to measure the magnetic field in the horizontal direction, and two complementary vertical structures are used to eliminate the error when the magnetic field in the same horizontal direction is measured.

  • Publication number: 20240229127
    Abstract: A method of detecting a lipid bilayer formed in a cell of a nanopore based sequencing chip is disclosed. An integrating capacitor is coupled with a lipid membrane, wherein the lipid membrane is between a working electrode and a counter electrode. An alternating current (AC) voltage is applied to the counter electrode. A voltage across the integrating capacitor is periodically sampled by an analog-to-digital converter (ADC). A change in the sampled voltage across the integrating capacitor in response to a change in the AC voltage is determined. Whether the lipid membrane comprises a lipid bilayer is detected based on the determined change in the sampled voltage across the integrating capacitor in response to the change in the AC voltage.

  • Patent number: 11982608
    Abstract: Disclosed is a method for measuring surface energy of aggregates based on static drop method, comprising (1) aggregates grinding and pretreatment; (2) obtaining the surface texture index; (3) calculating the surface energy based on static drop method experiment; (4) fitting to obtain a functional relationship between the surface texture index and surface energy; (5) calculating the surface energy of the original aggregate. The method considers the influence of the grinding process on the surface texture of the aggregates when measuring the surface energy of the aggregates, which significantly improves the accuracy of the static drop method test. The static drop method can be used to replace the vapor adsorption method to test the surface energy of aggregate, and the low-cost optical contact angle instrument can replace the expensive magnetic suspension weight balance system to test the surface energy of aggregate, which greatly reduces the test cost.
