Colorful nanofibrous membranes have attracted much attention for their visual varieties and various functionalities. In this article, a colored solution electrospinning process was used to fabricate colorful hydrophobic poly(vinyl butyral) (PVB)/cationic dye nanofibrous membranes (NFMs) successfully. The color and morphology of these as-spun nanofibrous membranes have been analyzed by colorimet...

The living cationic ring-opening polymerization of 2-oxazolines with fluorinated aromatic substituents was found to be strongly accelerated by o-fluoro substituents.

Due to the low content of adsorption-active groups in lignin, its application field adsorption is limited. Herein, we first prepared cationic kraft lignin acrylate, from which a (CKLA) hydrogel was further by acrylamide, and N, N’-methylenebisacrylamide. The morphology, compression properties swelling CKLA hydrogels were investigated. applied as an adsorbent for Congo red. effect dosages, initi...

Polyacrylic acid/ octavinyl polyhedral oligomeric silsesquioxane, nanocomposite hydrogel with 3-D network was synthesized via radical polymerization. Octavinyl polyhedral oligomeric silsesquioxane was used as crosslinker and nanofiller simultaneously in the preparation of the hydrogel. Hydrogel adsorption performance was determined by adsorption of methylene blue. The adsorption capacity was ev...

The expression of polyspecific membrane transporters is one important mechanism by which cells can obtain resistance to structurally different antibiotics and cytotoxic agents. These transporters reduce intracellular drug concentrations to subtoxic levels by mediating drug efflux across the cell envelope. The major facilitator superfamily multidrug transporter LmrP from Lactococcus lactis catal...

Methoxy-substituted aromatic diimines and corresponding homoleptic copper( i ) ii complexes as possible redox mediators in dye-sensitized solar cells.

The binding of Cibacron blue F3GA to dihydrofolate reductase (EC 1.5.1.3) from chicken liver an amethopterin-resistant Lactobacillus casei has been studied by difference spectroscopy. The blue dye binds to the enzyme from each species in a specific fashion with a 1:1 stoichiometry. However, the mode of interaction of the dye with the enzyme and the site of interaction on the enzyme are very dif...

The interactions between an anionic dye, Acid Green 25 AG and the two cationic surfactants tetradecyltrimethylammonium bromide TTAB, and hexadecyltrimethylammonium bromide CTAB in aqueous solutions far below the CMC are studied using the conductometric method at different temperature. The equilibrium constants and other thermodynamic functions for the process of dye-surfactant ion pair formatio...
