The present invention discloses a digital microfluidic device and a method for high-resolution melting curve analysis, relating to the field of digital microfluidics. The invention provides a functional substrate with hierarchical micro- and nanostructures for separating and arraying nanoliter-scale thin-film droplets at high resolution on a digital microfluidic platform, thereby enabling accurate one-time melting curve analysis. Through etching, the functional substrate exhibits superwettability with a contact-angle contrast greater than 170°. On an array of superhydrophilic patterns with inter-unit gaps of 50–500 μm, microliter-scale DNA samples are passively separated into high-resolution, nanoliter-scale thin-film droplets. Their characteristic thickness of 50 μm substantially reduces temperature variations within the droplets, making them suitable for high-resolution melting curve analysis. Furthermore, compared with conventional digital microfluidic devices, the digital microfluidic device provided by the present invention enables melting curve analysis with greater accuracy and higher resolution.

The present application provides a method, an apparatus, an electronic device, and a storage medium for assessing reliable demand response potential, and relates to the field of electric power technology. After obtaining multiple datasets corresponding to a target public building, the method trains a plurality of predefined submodels using training sets from the datasets. Calibration sets and test sets from the datasets are then separately input into the trained submodels to obtain upper and lower bounds of the energy consumption baseline for the target public building. A predefined thermal-parameter algorithm is applied to the baseline bounds to calculate upper and lower bounds of the indoor thermal resistance. Finally, based on the upper and lower bounds of the energy consumption baseline, the upper and lower bounds of the indoor thermal resistance, temperature-related comfort constraints, and a predefined assessment algorithm, the reliable demand response potential of the target public building is determined in the form of upper and lower bounds. This reduces the discrepancy between demand response potential estimated using a grey-box model and the actual response, thereby increasing the benefits of user participation in demand response and improving the reliability of power-system dispatch.

The present invention relates to the field of pharmaceutical technology and discloses the identification and application of novel mitophagy agonists. Specifically, the invention provides the use of mitophagy agonists in the manufacture of medicaments for preventing and/or treating fatty liver disease. Through systematic screening of a library of FDA-approved compounds, the invention demonstrates for the first time that flupentixol and vortioxetine possess mitophagy-inducing activity and that their effects are independent of the canonical PINK1/Parkin pathway. The invention further demonstrates that these two compounds effectively alleviate lipid accumulation and lipotoxicity in cellular models of metabolic dysfunction-associated steatotic liver disease (MASLD), thereby providing new therapeutic options for diseases associated with impaired mitophagy.

The present invention provides the use of a carboxyl-containing organic compound as an additive for water electrolysis for hydrogen production. An electrolyte-optimization strategy is employed to enhance the catalytic performance of the catalytic electrode. The carboxyl-containing organic compound can also remove impurity ions from the electrolyte and improve catalyst stability. When added to an alkaline electrolyte, the carboxyl-containing organic additive preferentially coordinates with metal ions on the catalyst surface, thereby anchoring itself to the surface. This interaction modulates the electronic structure of the surface metal species and enhances their stability, resulting in significant improvements in the catalyst’s intrinsic catalytic activity and durability. Accordingly, through simple addition to the electrolyte, the carboxyl-containing organic compound of the present invention can purify the electrolyte, stabilize the electrode surface, significantly enhance the kinetics of the oxygen evolution reaction (OER), and improve the overall energy efficiency of the electrolyzer.
