In order to contain the movement of organic contaminants in groundwater, a subsurface sorption barrier consisting of sand or clay minerals coated with a cationic surfactant has been proposed.
A mineral coating called kime is applied to consolidate, or strengthen, the cast stone.
The mineral coating provided an effective mechanism for growth factor binding and release.
We also demonstrated sustained release of all growth factors with release kinetics that were strongly dependent in the solubility of the mineral coating.
Desert varnish, also called Patina, thin, dark red to black mineral coating (generally iron and manganese oxides and silica) deposited on pebbles and rocks on the surface of desert regions.
To modulate the properties of the mineral coating, which we hypothesized would dictate growth factor release, we used carbonate (HCO3) concentration in mSBF of 4.2 mm, 25 mm, and 100 mm.
In this study we hypothesized that the release of plasmid DNA from CaP coatings formed on poly(lactide co-glycolide) (Plactide co-glycolide be dePLGdent on both the intrinsubstratesties of the CaP mineral coating and the surrounding solution conditions.
This means that tailored PMBs can be designed with both improved in-service performance at medium-high temperatures and reduced viscosity to facilitate polymer-bitumen mixing, mineral coating and asphalt mix laydown/compaction at lower temperatures.
In addition, we showed sustained release of multiple growth factors, with release kinetics that were controllable by varying the identity of the growth factor or the CO32− content in the mineral coating.
Elemental maps captured by scanning electron microscopy for a quartz grain from a granite sample deployed in the humid (Calhoun hardwood forest) environment (Fig. 4d) that show the distribution of surface carbon and iron (mineral coating), subsurface silicon of underlying quartz, potassium and aluminum (likely from an adjacent feldspar) together with a SEM micrograph of the sample area.
