The possibility to fabricate marine collagen porous structures crosslinked with genipin under high pressure carbon dioxide is investigated. Collagen from shark skin is used to prepare pre-scaffolds by freeze-drying. The poor stability of the structures and low mechanical properties require crosslinking of the structures. Under dense CO2 atmosphere, crosslinking of collagen pre-scaffolds is allo...
In the case of fracturing reservoirs using fluids, size damage to proppant conductivity caused by treatment fluids is significant, which greatly influence effective execution hydraulic operations. The fluid should be characterized minimum a fracture filled with proppant. A laboratory research procedure has been developed study effect foamed and non-foamed in fractures material. paper discusses ...
To provide scientific guidance for the use of foamed concrete (FC) in construction engineering, a thermal conductivity calculation method, based on fractal model FC, has been developed. The (TC) FC tested by transient planar heat source method order to verify reliability proposed model. was made cement, fly ash, and ore powder, cured under natural conditions 7 d, 14 28 42 respectively. TC gradu...
