Calf thymus DNA characterization and its adsorption on different silica surfaces
(Royal Society of Chemistry, 2015)
DNA adsorption is the initial stage of gene therapy for drug delivery systems and solid phase extraction methods of DNA purification. High pore volume and high adsorption capacity are simple requirements not only for ...
A rhodamine/BODIPY-based fluorescent probe for the differential detection of Hg(ii) and Au(iii)
(Royal Society of Chemistry, 2014-02)
We described the design and synthesis of a molecular sensor based on a rhodamine/BODIPY platform that displayed differential fluorescence responses towards Hg2+ and Au3+ and demonstrated its utility in intracellular ion imaging.
Optical and surface properties of zinc oxide nanoparticles dried by conventional and supercritical ethanol drying techniques
(Research India Publications, 2014)
Zinc oxide (ZnO) nanoparticles were synthesized by conventional (ZnO-A) and supercritical ethanol drying (ZnO-B). Nitrogen adsorption/desorption analyses were performed to determine the surface areas of the powders. The ...
Phonon scattering in graphene over substrate steps
(American Institute of Physics Publising, 2014-10)
We calculate the effect on phonon transport of substrate-induced bends in graphene. We consider bending induced by an abrupt kink in the substrate, and provide results for different step-heights and substrate interaction ...
Effects of porosity on heat and mass transfer in a granular adsorbent bed
In the present study, the mechanism of heat and mass transfer in an annulus adsorbent is handled. The heat and mass transfer equations for the adsorbent bed and the mass balance equation for the adsorbent granules are ...
Dye adsorption behavior of Luffa cylindrica fibers
Using natural Luffa cylindrica fibers as adsorbent removal of methylene blue dye from aqueous solutions at different temperatures and dye concentrations was investigated in this study. Thermodynamics and kinetics of ...
Synthesis and characterization of bentonite/iron nanoparticles and their application as adsorbent of cobalt ions
This study reports the synthesis and characterization of iron nanoparticles in the presence of K10 bentonite. Introducing K10 during synthesis of iron nanoparticles resulted in a partial decrease in the aggregation of the ...
Kinetic estimation of the adsorbate distribution on the surface from adsorbed amounts
A phenomenological multilayer adsorption model for a well-dispersed, homogeneous, nonporous adsorbent and a molecular adsorbate is presented. The model provides explicit kinetic expressions associating the adsorbed amounts ...
The use of metal piece additives to enhance heat transfer rate through an unconsolidated adsorbent bed
The effects of metal piece additives on effective thermal conductivity and diffusivity of an unconsolidated adsorbent bed in which adsorbent is silica gel were investigated. The metal piece additives were copper, brass, ...
Clinoptilolite-rich mineral as a novel carrier for the active constituents present in Ginkgo biloba leaf extract
The possible use of clinoptilolite-rich mineral as a novel carrier for the active constituents present in Ginkgo biloba leaf extract solutions was investigated. The flavonoid aglycone constituents were found to be selectively ...
