Dissociation of Nicotine from Acetylcholine-Binding Protein under Terahertz Waves Radiation.

The binding of nicotine (NCT) to acetylcholine-binding protein (AChBP) plays an important role in synaptic transmission and neurotransmitter regulation. However, effectively regulating their binding or dissociation processes remains a challenging problem. In this study, we employed all-atom molecular dynamics (MD) simulations to systematically investigate the impact of external terahertz (THz) waves on the binding kinetics between AChBP and NCT.

[Treating Simulated Dye Wastewater by an Copper Ferrite Process].

Four types of simulated dye wastewater containing methylene blue, tartrazine, Congo red, and crystal violet were treated by an copper ferrite process, and the influencing factors of the operational parameters in this process were studied. The main mechanism of dye removal was suggested by reaction thermodynamics and solid products characterization for methylene blue removal. The results showed that an copper ferrite process could effectively remove four kinds of simulated dyes by adjusting reaction conditions appropriately.

[Adsorption of Methylene Blue and Cu(Ⅱ) by Activated Carbon/Macromolecule Composite Hydrogel].

Activated carbon/alginate/poly(vinyl alcohol) composite macromolecule hydrogels (CAP) were prepared as adsorbents to study their adsorption performance for methylene blue (MB) and Cu in aqueous solution. The effect of dosage, pH, temperature, contact time, and initial concentrations of MB and Cu on the adsorption process was investigated. SEM, FTIR, and BET analyses were conducted to identify the physicochemical properties of CAP.
