Fast preparation method of silk fibroin-hyaluronic acid complex gel
InactiveCN106492279AIncreased external resistance to enzymatic hydrolysisReduce the rate of degradationProsthesisOperabilityRapid prototyping
The invention relates to a fast preparation method of silk fibroin-hyaluronic acid complex gel. The fast preparation method comprises the following steps: dissolving silk fibroin obtained by degumming, preparing a regenerated silk fibroin solution through dialysis, mixing the regenerated silk fibroin solution with hyaluronic acid, and finally preparing the fast complex gel under the action of a crosslinking agent. Compared with a conventional hyaluronic acid gel formed by pure crosslinking, the complex gel can be fast formed and has the advantages that by adding the silk fibroin, the gelating time is effectively shortened, the degrading speed of the gel is reduced, the stay time for tissue repairing and filling is prolonged, and the operability is improved; compared with pure silk fibroin hydrogel, the complex gel has the advantage that by adding the hyaluronic acid, the shortcomings of low toughness, fragility and the like of the silk fibroin hydrogel are overcome. The method for preparing the complex gel is simple in process and short in gelating time; a novel method is provided for the preparation of functional complex gel; the prepared complex gel can be used in the field of medicinal health, tissue engineering, environment protection and the like.

System and method integrating road surface runoff collection, purification, storage and utilization for plants
ActiveCN103374972AWidely used valueReduce capacity spaceFatty/oily/floating substances removal devicesSewerage structuresEngineeringHazardous materials transportation
The invention relates to a system and a method integrating road surface runoff collection, purification, storage and utilization for plants. A biological planting groove lower than a road surface is used for collecting and processing road surface runoff at an initial stage and formed by stacking a planting soil layer, an infiltration filtering layer, a supporting layer, a water storage layer, an impervious layer and the like from the top to the bottom. The road surface runoff at a later stage is collected in a level observing well separated in the groove through an overflowing groove on the side of the biological planting groove and can be discharged directly through a lateral wall water discharging pipe. The collected road surface runoff at the initial stage is calculated according to an area rainstorm intensity formula and collecting time, and on the basis of the calculated road surface runoff at the initial stage, filling material texture and thickness, soil infiltration capacity, a soil surface distance and an overflow distance are combined to distribute filling materials of the planting soil layer and the water storage layer. Storage water is extracted by an extraction device and utilized for road surface plants. The system and the method are applicable to collection, processing and comprehensive utilization of the road surface runoff which is at the initial stage and has a pollution effect and emergency management of a road environment under the condition of leakage of dangerous goods during transportation.

ActiveCN106368264BIncrease moistureGood water storage functionDrinking water installationThermal insulationEngineering
The invention provides a system for increasing soil moisture in an arid and semi-arid region. In a water-deficient region, a thermal insulation material and condensed water produced by a temperature difference generated in a refrigeration process are used for gradually increasing the moisture of soil. A cooling air water-collecting system is adopted, power is supplied to a refrigeration device by renewable energy sources such as solar energy or wind power, moisture is obtained from wet air through a refrigeration dewing method, and the condensed water is introduced into the soil through a water delivery pipe; moreover, a rock wool board is paved on the surface of the soil, so that evaporation of moisture on the surface of the soil is reduced or prevented, water is injected into the soil by continuously absorbing air moisture, the water accumulating function of the soil is added, and the moisture of the soil is further increased.
