Zwitterions and polyoxometalates (POMs) are two kinds of functional moieties with very different properties for applications in different fields. We have developed an effective strategy to successfully immobilize these two different moieties into the frameworks of porous hybrid materials, in which the POM units act as templates and photoactive moieties. These hybrid materials demonstrate remark...

Blast Furnace Slag (BFS) is a by-product of the iron ore processing industry with potential to be used in different industrial applications. In this research, BFS was examine its ability for dye removal from wastewater. The efficiency two types samples cationic methylene blue (MB) and acidic methyl orange (MO) dyes investigated results found that optimal conditions treatment wastewater were 80 ...

Contrast in confocal microscopy of phase-separated monolayers at the air-water interface can be generated by the selective adsorption of water-soluble fluorescent dyes to disordered monolayer phases. Optical sectioning minimizes the fluorescence signal from the subphase, whereas convolution of the measured point spread function with a simple box model of the interface provides quantitative asse...

The rate and mechanism of diffusion by anionic sulforhodamine B (SRB) dye molecules within organic nanotubes self-assembled from bolaamphiphile surfactants were investigated by imaging fluorescence correlation spectroscopy (imaging-FCS). The inner and outer surfaces of the nanotubes are terminated with amine and glucose groups, respectively; the former allow for pH-dependent manipulation of nan...

The noncovalent interaction between various polymethine dyes (45 compounds in total) and a spike protein (S), one of the main structural component SARS-CoV-2 coronavirus, is studied silico (molecular docking) to develop effective probes detect virus. energies spatial configurations complexes dye molecules with S are found. We showed that cationic neutral squarylium do not form stable S. Some an...

−Microsilica, one kind of industrial solid waste material, was utilized firstly to prepare a carbon-microsilica composite adsorbent (CMS). The prepared adsorbent was characterized with XPS, SEM and Gas sorption experiments. The results indicated the SO 3 H groups, which are very effective in capturing cationic organic dye, were introduced onto the surface of CMS; the Brunauer-Emmett-Teller (BET...

This work is reported on the synthesis of Fe3O4/eggshell nanocomposites in the absence of anystabilizer or surfactant. Fe3O4 magnetic nanoparticles were established on the egg shell. The adsorptionof Malachite green (MG) and Crystal violet (CV) as cationic dyes and Eriochrome Black T (EBT) as ananionic dye by magnetite nanoparticles loaded egg shell (MNLES) and magnetite nanop...

Methylene blue, a prevalent cationic type dye, has been extensively utilized in textile industry. Lignin generates as byproduct and its utilization is required to add potential economic benefit of biorefinery process. Lignin-derived porous biochar, promising adsorbent, was propitiously prepared by chemical modification with different oxidation number manganese compounds (KMnO4, MnSO4, MnO2). Th...

Cationic dye - basic red 2 (BR2) was removed from aqueous solutions by sulfuric acid activated waste Gossypium hirsutum seeds (WGSAB). The main and interactive effects of five process variables such as, adsorbent dose (1.25 – 5 g/L), initial dye concentration (100–300 mg/L), contact time (1–3 h),  pH (2 – 12) and temperature (20 – 400C) were investigated via  response su...

The present study prepares alkali lignin (AL) via acidification of black liquor, obtained from a pulp and paper factory. The average molecular weight of AL (equal to 2,530 g/mol) has been determined with gel permeation chromatography. AL has been modified by ethylene glycol, while lignin nanoparticles (LN) has been prepared through acid precipitation technology, their size being assessed by mea...
