The present invention discloses a carbon nanodot–amino acid composite reagent, as well as a preparation method and use thereof. The carbon nanodot–amino acid composite reagent comprises carbon nanodots and amino acids composited with each other, wherein the surfaces of the carbon nanodots are provided with electron-withdrawing groups. By compositing amino acids with carbon nanodots having electron-withdrawing groups on their surfaces, the two are bonded through hydrogen bonds to form the carbon nanodot–amino acid reagent, without requiring a complicated purification procedure. The reagent possesses the properties of both amino acids and carbon dots, readily binds to cell membranes and penetrates cells, and thereby facilitates cellular uptake. After compositing, the reagent exhibits a relatively high fluorescence quantum yield in aqueous solution and can be used for biological imaging. In addition, the carbon nanodot–amino acid reagent can effectively reduce the amount of fat in cells and in vivo, thereby achieving a weight-loss effect.

The present invention relates to the field of electrolytic water splitting for hydrogen production and discloses an electrocatalyst, as well as a preparation method and use thereof. The preparation method comprises the following steps: in the presence of a conductive substrate, subjecting an aqueous solution containing a molybdenum source, a cobalt source, and a fluorine source to a hydrothermal reaction; thermally treating the resulting product under a hydrogen-containing reducing atmosphere to obtain an MoO₂/CoMoO₃ composite structure supported on the conductive substrate; and performing in situ electrochemical reconstruction of the supported MoO₂/CoMoO₃ composite structure in an alkaline electrolyte to obtain the electrocatalyst. The present invention addresses the drawbacks of conventional non-noble-metal catalysts, including low activity, susceptibility to corrosion, and poor chlorine resistance. The resulting electrocatalyst requires an overpotential of only 186 mV at an industrial-grade current density of 500 mA·cm⁻² and exhibits only minor potential variation during 5,000 hours of continuous operation. It therefore demonstrates activity and stability far exceeding those of single-phase materials and is suitable for industrial-scale hydrogen production applications.

The embodiments of the present application provide a piezoelectric microelectromechanical systems (MEMS) microphone, a method for manufacturing the same, and applications thereof, belonging to the field of MEMS technology. The microphone according to the embodiments includes a substrate, a diaphragm, an oxide layer, a piezoelectric layer, and an electrode layer sequentially stacked one above another. The electrode layer includes a voice-sensing electrode, an infrasound-sensing electrode, and a drive electrode. The microphone can perform voice detection based on the direct piezoelectric effect using the diaphragm, the piezoelectric layer, and the voice-sensing electrode. Simultaneously with voice detection, the inverse piezoelectric effect is utilized by applying a continuously controlled alternating voltage to the drive electrode, thereby driving the diaphragm to oscillate at its resonant frequency and maintain its vibration mode. A disturbance signal produced by the infrasound signal on the resonant frequency of the diaphragm is then read out, converting the low-frequency physical quantity of infrasound into a measurable disturbance signal. This addresses low-frequency attenuation caused by slit-design and packaging constraints.

The present invention discloses a distribution system planning method for addressing the seasonal imbalance and year-by-year intensification of heat waves, belonging to the field of power system planning and operational optimization. The method first collects multi-year hourly meteorological data and basic distribution system data for a target city, and generates multi-timescale heat-wave meteorological trajectories incorporating both short-term seasonal fluctuations and long-term intensification trends. Meteorological variables are then converted, through source-load meteorological sensitivity mapping, into building cooling-load amplification factors and renewable-energy output correction factors, thereby obtaining nodal net power injections. A heat-wave source-load imbalance risk index is calculated to screen key heat-wave scenarios. Based thereon, nodal net power injection envelopes and a heat-wave disturbance budget are constructed to form a compact composite uncertainty set. A progressive two-stage robust planning model is then established and solved. The present invention reduces the computational complexity associated with high-dimensional heat-wave scenarios and improves the planning adaptability, operational safety, and engineering feasibility of urban distribution systems under heat-wave conditions.

The present invention discloses a supramolecularly modified polymer, supramolecular polymer microspheres, and preparation methods thereof. The supramolecular polymer microspheres comprise a guest-molecule drug, a supramolecularly modified polymer, and PLGA, wherein the supramolecularly modified polymer preferably has a weight-average molecular weight (Mw) of 40,000. The invention further discloses the use of the supramolecular polymer microspheres in the treatment of acromegaly. The microspheres of the present invention enable sustained, slow drug release for more than two months, substantially reducing the frequency of injections and improving patient compliance. In addition, the raw materials and preparation process designed according to the present invention are relatively low in cost and readily scalable.
