Ethanol influenced fast microwave-assisted extraction for natural antioxidants obtaining from spent filter coffee
(Elsevier, Amsterdam, 2013)
Ethanol influenced microwave-assisted extraction was performed for obtaining of natural antioxidants from spent filter coffee. The process included response surface methodology which represented the significance of both ...
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 ...
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), ...
Toward Optimum Working Fluid Mixtures for Organic Rankine Cycles using Molecular Design and Sensitivity Analysis
(Amer Chemical Soc, Washington, 2013)
This work presents a Computer-Aided Molecular Design (CAMD) method for the synthesis and selection of binary working fluid mixtures used in Organic Rankine Cycles (ORC). The method consists of two stages, initially seeking ...
Investigation of silver impact on hydroxyapatite/lignin coatings electrodeposited on titanium
(Elsevier Science Sa, Lausanne, 2013)
Silver doped hydroxyapatite (HAP) [Ca9.95Ag0.05(PO4)(6)(OH)(2)] composite coatings with natural polymer organosolv lignin (Lig) were produced by electrophoretic deposition (EPD) on titanium. Coatings were characterized by ...
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 ...
Properties and drug release profile of poly(N-isopropylacrylamide) microgels functionalized with maleic anhydride and alginate
(Springer, New York, 2013)
This study highlights the advantages of functionalized poly(N-isopropylacrylamide) (PNIPAAm) microgels over pure PNIPAAm microgels in terms of polymer network properties and drug release profiles. PNIPAAm network was ...
Environmentally friendly solutions of liquid poly(ethylene glycol) and imidazolium based ionic liquids with bistriflamide and triflate anions: Volumetric and viscosity studies
(Elsevier Science Bv, Amsterdam, 2013)
In this paper, densities and viscosities of the solutions of PEG200 with two imidazolium ionic liquids, 1-ethyl-3-methylimidazolium bis{(trifluoromethyl)sulfonyl}amide ([C(2)mim][NTf2]) and 1-ethyl-3-methylimidazolium ...
The influence of Ce-based coatings as pretreatments on corrosion stability of top powder polyester coating on AA6060
(Elsevier Science Sa, Lausanne, 2013)
Cerium-based conversion coatings (CeCCs) are one of the most prospective alternatives to the widely used chromate conversion coatings (CCCs) due to their anticorrosion efficiency, environmentally friendly nature and low ...
The influence of anion type in electrolyte on the properties of electrodeposited Zn-Mn alloy coatings
(Elsevier Science Sa, Lausanne, 2013)
Zn - Mn alloy electrodeposition on steel electrode, in electrolytes containing chloride or sulfate anions, was investigated by chronopotentiometry. Galvanostatically obtained electrodeposits were characterized by X-ray ...
