A simple, environmentally friendly and cost-effective nonsurfactant template method was used to synthesize tannic-acid-templated mesoporous silica nanoparticles (TMSNs), and then dopamine functionalized TMSNs (Dop-TMSNs) which was synthesized by a facile and biomimetic coating strategy, was developed as a new sorbent for the removal of Cu2+ from aqueous… (More)
Prior studies showed that corporate social responsibility in developed countries could reduce the losses when negative events happened. Corporate social responsibility had the effects of injury insurance. Using a sample of listed companies in china that were denounced by security regulators, researches whether earlier corporate social responsibility acts… (More)
Dopmine functionalized mesoporous onion-like silica (DPMS) was synthesized via a biomimetic coating, and lipase Candida sp. 99-125 (LCS) was immobilized in DPMS (LCS@DPMS) by physical adsorption in this study. The DPMS was characterized by SEM, TEM, BET and FT-IR, and it was shown that the DPMS had clear multishell structures with large surface area of 419… (More)
A facile and promising approach was developed to fabricate enzyme-based 3D-ordered macroporous biocatalysts (enzyme-based inverse opals) by using the colloidal crystal templating method. Horseradish peroxidase- and amylase-based inverse opals were prepared, which verified that this method is suitable for various enzymes.
