This invention discloses a method for the biological drying of sludge, comprising the following steps: baking biomass materials, mixing the resulting baked product with sludge, biochar materials, and a conditioner for biological drying, thereby completing the sludge drying process. In this invention, by biologically drying the mixture of baked product, sludge, biochar materials, and conditioner, not only can the self-generated heat within the system be used to effectively dewater the sludge in a very short time, but the bioavailability of the microbial carbon source can also be improved, effectively reducing the generation of polluting gases. This method can effectively reduce the emission of polluting gases while achieving rapid dewatering. It has advantages such as simple process, low treatment cost, low energy consumption, high drying efficiency, good dewatering effect, low polluting gas production, and low content of toxic and harmful components in the dried product. It can solve the problems of biomass resource waste and pollution, achieve sludge reduction and resource utilization, and has high returns and good application prospects.

The application discloses a method for preparing electronic-grade insulating pulp from bamboo, and relates to the technical field of insulating pulp production and preparation, and comprises the following preparation steps: step A, collecting bamboo raw materials in Hunan area; step B, flaking operation, bamboo is flaked and cut into pieces in a bamboo processing factory; step C, water washing operation, bamboo pieces are washed to balance water content; step D, cooking operation, bamboo pieces are cooked by adopting sulfite process, and the yield of the crude pulp is controlled to be 40-50%; step E, screening operation; step F, beating operation; step G, sheeting operation and strength detection. The method for preparing electronic-grade insulating pulp from bamboo has certain regionalism by adopting locally planted bamboo in Hunan, the prepared electronic-grade insulating pulp reaches the superior standard, and the prepared electronic-grade insulating pulp has the quality index that the conductivity is less than 3 us / cm by adopting deionized water for washing in the whole process.

This invention discloses a semiconductor component with a finger-like metal wire-wound layout, comprising a semiconductor substrate, a first pad, and a second pad. The semiconductor substrate includes a first region and a second region with different polarities. The first pad is disposed on the first region. The first pad comprises multiple layers of metal and has a multilayer height. The second pad is disposed on the second region. The second pad comprises a single layer of metal and has a single-layer height. The multilayer height is greater than the single-layer height, such that the multilayer metal side area of ​​the first pad relative to the second pad is greater than the single-layer metal side area of ​​the second pad relative to the first pad.

This invention discloses a PSA aptamer sensor based on a screen-printed electrode, its preparation, and detection method. In this invention, a composite material of AuNPs and graphene aerogel is used to modify the surface of a screen-printed electrode. The aptamer is modified onto the sensor by forming gold-sulfur (Au-S) bonds with a thiol-modified DNA single-stranded aptamer. Excess gold active sites are blocked with MCH to construct the PSA aptamer sensor. A certain concentration of PSA and UA is selected and incubated with the sensor. The EIS test method is used to detect PSA by recording its impedance changes, and the detection limit of the sensor is obtained. Utilizing the advantages of large-scale mass production and low cost of screen printing technology, combined with the excellent physical and electrical properties of nanomaterials, an electrochemical sensor for the detection of prostate-specific antigen (PSA) is prepared, enabling convenient, efficient, and low-cost detection, providing a new approach for prostate cancer patients to be detected outside of hospitals and laboratories.
