Surface Studies on HgCdTe Using Non-aqueous Iodine-Based Polishing Solution

Application of response surface methodology for optimization of fluoride adsorption from aqueous solution using MgO-based nanocomposites

Deleterious effect of high concentration fluoride in water resources on the healthof human. The MgO supported Fe-Co-Mn nanoparticles were produced via coprecipitationmethod and characterized by SEM and FTIR techniques. In the work,the adsorption process optimization was performed by response surface modelingwith the help of Minitab 16 software. The effect of independent ...

NaI Aqueous Solution Surface Probed by Photoemission

For a NaI aqueous solution negative surface excess is inferred from the evolution of the ion photoemission signal as a function of the salt concentration. The experiments were performed using a 6μm diameter liquid microjet providing a free vacuum surface, which allows water molecules to evaporate without collisions, and hence enables the direct detection of photoelectrons originating from the l...

Aqueous Solution Surface Chemistry of Carbon Nanotubes

Spectroscopic studies of solutes in aqueous solution.

Absorption and fluorescence characteristics of aqueous solutions of salts, sugars, and amino acids were studied using UV-vis spectroscopy and spectrofluorometry. Motivation stemmed from unanticipated absorption spectral and fluorescence features of the "exclusion zone" seen adjacent to various hydrophilic surfaces. Those features implied a structure distinct from that of bulk water (Adv. Colloi...

Removal of caffeine from aqueous solution using multi-wall carbon nanotubes: kinetic, isotherm, and thermodynamics studies

The occurrence of contaminants in wastewaters, and their behavior during wastewater treatment and production of drinking water are key issues to re-use water resources. The present research aims to remove caffeine from aqueous solutions via adsorption technique, using Multi-Wall Carbon Nanotubes (MWCNTs) as an adsorbent under different experimental conditions. The processing variables such as p...
