The biosorption of Cr(VI)_ and Cr(III)_ Arthrobacter species (Arthrobacter globiformis and Arthrobacter oxidas) was studied simultaneous application dialysis and atomic absorption analysis. Also biosorption of Cr(VI) in the presence of…
The biosorption of Cr(VI) Arthrobacter species (Arthrobacter globiformis 151B and Arthrobacter oxides 61B) after growth in the presence of Zn (II) ions at different Na (I) concentrations was studied application using dialysis and atomic…
The biosorption of Ag(I)_ Arthrobacter species (Arthrobacter globiformis 151B and Arthrobacter oxidas 61B) was studied at simultaneous application of dialysis and atomic absorption analysis. The biosorption constants and nature of…
The biosorption of Au(III) - Spirulina platensis and Au(III) - Arthrobacter species (Arthrobacter globiformis and Arthrobacter oxidas) were studied at simultaneous application of dialysis and atomic absorption analysis. Also biosorption of…
The absorption characteristics of Cr(III), Cr(VI), Cu(II) ions on intact living cells Spirulina platensis (pH9.6) were studied by using a UV-VIS spectrophotometer. Also biosorption of these ions with cyanobacteria Spirulina platensis were…
Biosorption of Ag(I)-Spirulina platensis for different pH were investigated using dialysis and Atomic-absorbtion analysis. It was shown, that the biosorption constant for Ag(I) Spirulina platensis complex and the capacity depend on the…
The reduction reaction of turning Cr(VI) into Cr(III) by appropriate oxidants together with nanoscale catalysts in contaminated soil and water received significant amount of attention for its environmental benefits. Single-atom catalysts…
Recovery of multispecies oral biofilms is investigated following treatment by chlorhexidine gluconate (CHX), iodine-potassium iodide (IPI) and Sodium hypochlorite (NaOCl) both experimentally and theoretically. Experimentally, biofilms taken…
The variation of the optical absorption of carbon nanotubes with their geometry has been a long standing question at the heart of both metrological and applicative issues, in particular because optical spectroscopy is one of the primary…
Chlorinated hydrocarbon compounds are of environmental concerns, since they are toxic to humans and other mammals, are widespread, and exposure is hard to avoid. Understanding and improving methods to reduce the amount of the substances is…
The effects of pH, ionic strength and temperature on sorption of Eu(III) on attapulgite were investigated in the presence and absence of fulvic acid (FA) and humic acid (HA). The results indicated that the sorption of Eu(III) on attapulgite…
In the course of our investigations of the adsorption of ions to the air-water interface, we previously reported the surprising result that doubly-charged carbonate anions exhibit a stronger surface affinity than do singly-charged…
Over the last decades, photoreceptive proteins were extensively studied with biophysical methods to gain a fundamental understanding of their working mechanisms and further guide the development of optogenetic tools from them. Time-resolved…
The adsorption of CO on unreconstructed and reconstructed Ir{100} has been studied, using a combination of density functional theory and thermodynamics, to determine the relative stability of the two phases as a function of CO coverage,…
A theory is presented which quantitatively accounts for the cooperative adsorption of cationic surfactants to anionic polyelectrolytes. For high salt concentration we find that the critical adsorption concentration (CAC) is a bilinear…
Organic superalkalis are carbon-based species possessing lower ionization energy than alkali atom. In the quest for new organic superalkalis, we study the MC6Li6 (M = Li, Na, and K) complexes and their cations by decorating…
We present multi-epoch KPNO Coude Feed observations of interstellar NaI and CaII absorption toward the bright star rho Leo. Comparisons of the NaI profiles observed over a period of 8 years reveal significant temporal variations in the NaI…
The main object of this investigation was to shed light on the information on the level of Cu uptake by Pseudomonas aeruginosa that has been previously isolated from patients using Gram-negative E. aerogenes ans a Gram-positive Bacillus…
We investigated the adsorption of a single atom, hydrogen and aluminum, on single wall carbon nanotubes from first-principles. The adsorption is exothermic, and the associated binding energy varies inversely as the radius of the zigzag…
The resistivity and thermopower of polycrystalline (Na,Ca)Co_2O_4 were measured and analyzed. Both the quantities increase with x, suggesting that the carrier density is decreased by the substitutions of Ca^{2+} for Na^{+}. Considering that…
