A Study of Applicability of Nonlinear Frequency Response Method for Investigation of Gas Adsorption Based on Numerical Experiments
(Amer Chemical Soc, Washington, 2013)
A study of the applicability of the Nonlinear Frequency Response (NFR) approach for investigation of equilibrium and kinetics of gas adsorption, based on numerical simulations, is presented. Pressure responses of a batch ...
Particle velocities in quasi two-dimensional water fluidized beds of spherical particles
(Elsevier, Amsterdam, 2013)
Particle velocities have been measured in two-dimensional water fluidized beds of mono-sized spherical glass particles d(p) = 1.94, 2.98, 4.00 and 6.00 mm in diameter. For each particle size, a separate column was constructed ...
Carboxylic acids and polyethylene glycol assisted synthesis of nanocrystalline nickel ferrites
(Elsevier Sci Ltd, Oxford, 2013)
Different synthesis methods for the preparation of nanocrystalline nickel ferrites are reported: the thermal decomposition of precursors, made of: (i) metal-nitrate salts with carboxylic acids (citric, malonic and tartaric), ...
Removal of Co2+ ions from aqueous solutions using iron-functionalized sepiolite
(Elsevier Science Sa, Lausanne, 2012)
The efficiency of iron-functionalized sepiolite for the removal of Co2+ ions from aqueous solutions was determined under different experimental conditions, using the batch method. The ionization constants of the surface ...
Nano- and Micro-Scale Surface Modification of FCC Metal Using High Submerged Cavitating Water Jet
(Springer, New York, 2013)
The aim of this paper is to establish a possible application of the cavitation phenomenon as an efficient method to modify surface properties at the nano and micro levels. Commercial-purity copper was subjected to high ...
Hardwood lignin pyrolysis in the presence of nano-oxide particles embedded onto natural clinoptilolite
(Elsevier Science Bv, Amsterdam, 2013)
In this study the catalytic activity of Na-rich and MO-containing natural clinoptilolite (MO - nanopartides of NiO, ZnO, or Cu2O) was studied in the pyrolysis of hardwood lignin. The clinoptilolite samples exhibit different ...
Removal of Sulfur Compounds from Mineral Insulating Oils by Extractive Refining with N-Methyl-2-pyrrolidone
(Amer Chemical Soc, Washington, 2012)
Copper sulfide deposits in the insulation systems of power transformers decrease the dielectric properties of the insulation and therefore constitute a significant risk for the operation of power transformers. Disulfides, ...
Mucoadhesive Gelatin Buccal Films with Propranolol Hydrochloride: Evaluation of Mechanical, Mucoadhesive, and Biopharmaceutical Properties
(Pharmaceutics, 2021)
This study processes and characterizes propranolol hydrochloride/gelatin mucoadhesive buccal films. Two types of gelatin are used: Gelatin from porcine skin, type A (GA), and gelatin from bovine skin (GB). The influence ...
Advances in interactive supported electrocatalysts for hydrogen and oxygen electrode reactions
(Elsevier, 2007)
Magneli phases [A. Magneli, Acta Chem. Scand. 13 (1959) 5] have been introduced as a unique electron conductive and interactive support for electrocatalysis both in hydrogen (HELR) and oxygen (OELR) electrode reactions in ...
Alginate hydrogel microbeads incorporated with Ag nanoparticles obtained by electrochemical method
(Elsevier Science Sa, Lausanne, 2012)
An innovative method was developed for production of alginate hydrogel microbeads incorporated with silver nanoparticles (AgNPs) based on electrochemical synthesis followed by electrostatic extrusion. AgNPs were synthesized ...
