A parametric study on isobaric adsorption process in a closed adsorbent bed
A numerical study on heat and mass transfer in an annular adsorbent bed filled with adsorbent granules for an isobaric adsorption process is performed. In order to reduce the number of independent parameters that influences ...
Methylene blue adsorption from aqueous solutions to flexible poly(vinyl chloride) silica composites
Methylene blue (MB) adsorption studies were performed with poly(vinyl chloride)-(dioctyl phthalate)-silica composites, which were obtained by using plastisol-plastigel technology. The films were flexible, having elastic ...
Moisture sorption and thermal characteristics of polyaramide blend fabrics
Four types of fabrics woven from various polyaramid fibers of Nomex and Kevlar blends were characterized by morphology, XRD, elemental analysis, thermal analysis, and moisture adsorption isotherms. The blends consisted of ...
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 ...
A study of adsorption of water vapour on wool under static and dynamic conditions
(Kluwer Academic Publishers, 1998-01)
Adsorption of water vapour on wool provides not only textile comfort, but also convenience in transportation due to increase in its bulk density. The adsorption and desorption isotherms of water vapour for wool were ...
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 ...
CO2 and N2 adsorption on the acid (HCl, HNO 3, H2SO4 and H3PO4) treated zeolites
CO2 and N2 adsorption on the acid treated natural and synthetic zeolites at 5◦C and 25◦C was studied. The system heterogeneity was higher for CO2 than N2 adsorption and decreased with acid treatment.
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 ...
Methods of humidity determination Part II: Determination of material humidity
Part II covers the most common methods of measuring the humidity of solid material. State of water near solid surfaces, gravimetric measurement of material humidity, measurement of water sorption isotherms, chemical methods ...
Diffusion mechanism of water vapour in a zeolitic tuff rich in clinoptilolite
The adsorption kinetics of H2O in a clinoptilolite rich zeolitic tuff was experimentally investigated at 18°C. In the identification of the diffusion mechanism the isothermal adsorption model equation was used. It was found ...
