Techniques for carbon sequestration and storage site selection are presented. The techniques include: obtaining range estimations of criteria for potential carbon sequestration and storage sites; selecting random criteria values in respective range estimations; forming a decision matrix from the random criteria values; weighing the decision matrix to obtain representative vectors; scoring at least some the potential carbon sequestration and storage sites according to similarities of respective potential carbon sequestration and storage site representative vectors to a best vector and to a worst vector; ranking the potential carbon sequestration and storage sites according to the scores; repeating the selecting, forming, weighing, scoring, and ranking a plurality of times to obtain a plurality of sets of scores and a plurality of rankings; displaying a visualization of the plurality of rankings; and selecting a carbon sequestration and storage site from among the potential carbon sequestration and storage sites based on the visualization.

Carbon sequestration and storage site selection and usage

Disclosed is an injection molding method for a degradable intravascular stent with a flexible mold core structure. The injection molding method includes the following steps: Step 1, winding a metal rod with a flexible metal film, and applying an inward bending stress to the flexible metal film; Step 2, fixing the flexible metal film to the metal rod, and processing a complementary structure of the degradable intravascular stent on the surface of the flexible metal film; Step 3, performing injection molding processing; Step 4, ending the injection molding, removing the mating body of the flexible metal film and the metal rod and the degradable intravascular stent formed on the surface of the flexible metal film by injection molding, performing cooling, separating the metal rod from the flexible metal film, withdrawing the metal rod, and then removing the flexible metal film to obtain a formed degradable intravascular stent.
