The present invention discloses a method for preparing a photochromic molecule/alumina nanoporous membrane and an application thereof, and belongs to the field of nanomaterial-based detection. The nanopores of the alumina nanoporous membrane are open at one end and sealed at the other, with a nan channel array structure formed therebetween. The sealed end serves as a barrier layer of the alumina nanoporous membrane and, at the microscale, exhibits an array of hemispherical protrusions in a hexagonal close-packed arrangement. The photochromic molecules are grafted onto the open side at the top of the alumina nanoporous membrane and onto the inner walls of the intermediate channels. When spiropyran is used as the photochromic molecule, the resulting spiropyran/alumina nanoporous membrane can be controllably switched, through remote optical control, between an inert reactor and an active reactor for SO₂. This enables the construction of an on-demand detection device capable of long-term storage and real-time detection. Quantitative analysis of SO₂ can be achieved by monitoring the rectification current, thereby providing an entirely new approach for designing other on-demand nanofluidic sensing devices and enabling reliable detection.

A novel scorpion venom peptide, designated C9, was isolated and identified, and a novel peptide–poly(amidoamine) dendrimer complex, G5C9 (i.e., a nanoparticle), having glioblastoma (GBM)-targeting activity was constructed. Compared with peptide C9 alone, G5C9 exhibits significantly enhanced cellular uptake efficiency. G5C9 enters cells via endocytosis and targets lysosomes, thereby inhibiting lysosomal function and mTORC1, promoting the nuclear translocation of TFEB, and consequently inducing autophagic cell death. Accordingly, G5C9 provides a novel targeted anti-GBM approach both in vitro and in vivo.

The present invention discloses a fire-resistant foam material, as well as a preparation method and use thereof, and belongs to the technical field of composite materials. The fire-resistant foam material comprises the following raw materials, in parts by mass: 1–40 parts of gypsum, 1–50 parts of a foam stabilizer, 1–50 parts of a foaming agent, 1–80 parts of an auxiliary agent, and 10–150 parts of water. The foam stabilizer is selected from nanoparticles having an average particle size of 1–100 nm. According to the present invention, gypsum is incorporated into the fire-resistant foam material. Upon exposure to high temperatures, gypsum absorbs heat and releases water vapor through evaporation of its water of crystallization, thereby imparting favorable flame-retardant properties to the foam material. In addition, gypsum is dispersed at the Plateau borders of the foam to form bridging structures, thereby enhancing foam stability and reducing damage to the foam structure upon heating. In combination with the physical barrier formed by nanoparticles dispersed on the foam surface, the material can effectively stabilize the foam and improve fire-extinguishing performance.

The present application discloses a multimodal microwave sensor and a method for decoupled measurement of multiple parameters. The sensor comprises a first metal layer, a dielectric layer, a second metal layer, and a transmission member. The first metal layer is provided with a first microstrip feed line, a second microstrip feed line, and a trimode resonant coupling structure. By connecting the transmission member to a cantilever beam, the nonuniform elastic deformation of the cantilever beam under pressure causes corresponding asymmetric coupling changes in the trimode resonant coupling structure. This simultaneously induces two independently responsive sensing parameters: a change in resonant-frequency difference and a change in transmission amplitude. Accordingly, dual-parameter integrated sensing can be achieved without additional circuitry. The disclosed sensor effectively suppresses temperature drift and environmental electromagnetic interference, thereby improving the interference resistance and measurement reliability of the microwave pressure sensor, as well as the accuracy of pressure measurement and the operational stability of the device.

The present application provides a misalignment-tolerant coil array structure and a dual-channel resonant circuit, belonging to the technical field of electric vehicles. The structure comprises a receiving coil array and a transmitter. The receiving coil array and the transmitter are arranged in parallel, with a predetermined distance between the plane of the receiving coil array and the plane of the transmitter. Each first receiving coil in the receiving coil array is magnetically coupled to a transmitting coil of the transmitter, and each second receiving coil in the receiving coil array is also magnetically coupled to the transmitting coil. As the horizontal offset between the receiving coil array and the transmitter increases, a first mutual inductance between each first receiving coil and the transmitting coil increases, while a second mutual inductance between each second receiving coil and the transmitting coil decreases, such that the total mutual inductance of the misalignment-tolerant coil array structure remains constant. The present application can reduce the size of the misalignment-tolerant coil array structure and improve the misalignment tolerance of a wireless charging system.

The present invention pertains to the field of integrated circuits and discloses an analog-to-digital converter (ADC) incorporating a phase-locked-loop-based subrange ring-oscillator time-to-digital converter (TDC). The ADC employs a multi-channel time-interleaved architecture. At the front end, coarse quantization in the voltage domain is performed using a successive-approximation-register (SAR) circuit. The residual signal is amplified and converted from voltage to time, after which fine quantization in the time domain is performed by a back-end subrange ring-oscillator TDC. The design introduces RS-PL closed-loop control of the SRRO and uses a phase-locked loop for frequency multiplication. High resolution can be achieved using only two N-stage ring oscillators and a locking circuit. Frequency drift caused by process, voltage, and temperature (PVT) variations is compensated, thereby addressing the susceptibility of the minimum quantization time step in conventional TDCs to drift. A coarse-and-fine dual-loop subrange architecture, in combination with an all-digital calibration circuit, corrects boundary-crossing errors and phase-offset errors, thereby improving quantization accuracy. The entire oscillation source can be shared among multiple channels, effectively reducing hardware area and power consumption. The device features high speed, low power consumption, and strong interference immunity, making it suitable for high-speed communication applications.

The present invention pertains to the field of integrated circuits and discloses an analog-to-digital converter (ADC) incorporating a phase-locked-loop-based subrange ring-oscillator time-to-digital converter (TDC). The ADC employs a multi-channel time-interleaved architecture. At the front end, coarse quantization in the voltage domain is performed using a successive-approximation-register (SAR) circuit. The residual signal is amplified and converted from voltage to time, after which fine quantization in the time domain is performed by a back-end subrange ring-oscillator TDC. The design introduces RS-PL closed-loop control of the SRRO and uses a phase-locked loop for frequency multiplication. High resolution can be achieved using only two N-stage ring oscillators and a locking circuit. Frequency drift caused by process, voltage, and temperature (PVT) variations is compensated, thereby addressing the susceptibility of the minimum quantization time step in conventional TDCs to drift. A coarse-and-fine dual-loop subrange architecture, in combination with an all-digital calibration circuit, corrects boundary-crossing errors and phase-offset errors, thereby improving quantization accuracy. The entire oscillation source can be shared among multiple channels, effectively reducing hardware area and power consumption. The device features high speed, low power consumption, and strong interference immunity, making it suitable for high-speed communication applications.
