摘要: To better understand the adsorption of long-chain poly(1 → 4)-β-d-glucans on carbon surfaces as well interactions responsible for this adsorption, we use a comparative study involving mesoporous carbon–silica composite materials that have been etched to varying degrees and all-atom molecular dynamics simulations. The synthesized part etching consist an as-synthesized material (MCN-MSN), MCN-MSN-0.5 (composite consisting 50% by mass), MCN-MSN-0.3 70% MCN, in which silica was conducted using aqueous ethanolic solution either NaOH or HF. Data glucans these from concentrated HCl (37 wt %) demonstrate direct relationship between amount β-glu magnitude exposed mesopore surface area, systematically increases is also accompanied increase size during si...
