Wall effects on the velocities of a single sphere settling in a stagnant and counter-current fluid and rising in a co-current fluid
(Elsevier, Amsterdam, 2010)
Experimental results were obtained on the steady settling of spheres in quiescent media in a range of cylindrical tubes to ascertain the wall effects over a relatively wide range of Reynolds number values. For practical ...
Synthesis of submicron carbon spheres by the ultrasonic spray pyrolysis method
(Elsevier, Amsterdam, 2010)
Submicron carbon spherical particles were obtained by polycondensation of resorcinol and formaldehyde in a solution and subsequent ultrasonic spray pyrolysis of the prepared sol. Microscopic characterization indicates the ...
Microencapsulation of Flavors in Carnauba Wax
(MDPI, Basel, 2010)
The subject of this study is the development of flavor wax formulations aimed for food and feed products. The melt dispersion technique was applied for the encapsulation of ethyl vanillin in wax microcapsules. The surface ...
Bactericidal Efficiency of Silver Nanoparticles Deposited onto Radio Frequency Plasma Pretreated Polyester Fabrics
(Amer Chemical Soc, Washington, 2010)
The potential application of low-temperature radio frequency (RF) plasma for fiber surface activation in order to enhance the binding efficiency of colloidal silver nanoparticles onto the polyester fabrics and improve the ...
Introduction of cleaner production in the tank farm of the Pancevo Oil Refinery, Serbia
(Elsevier Sci Ltd, Oxford, 2010)
This work studies the introduction of cleaner production (UP) in the tank farm of the Pancevo Oil Refinery. From 2003 to 2008, substantial investments in storage technology and equipment were made in order to minimize the ...
The effect of ECAP and Cu addition on the aging response and grain substructure evolution in an Al-4.4 wt.% Mg alloy
(Elsevier Science Sa, Lausanne, 2010)
The effect of ECAP conducted at 200 degrees C on the grain substructure evolution in an AA5182 alloy and the same alloy with 1.2 wt.% Cu addition was investigated. Severe plastic deformation was found to accelerate the ...
Functionalization of PET Fabrics by Corona and Nano Silver
(SAGE Publications, 2010)
In this work, the antibacterial and other properties of polyester fabrics previously functionalized by corona and/or silver nano particles have been studied. Corona air plasma was used as a pretreatment of raw, washed and ...
Mechanical and magnetic properties of composite materials with polymer matrix
(Technical Faculty, Bor, 2010)
Many of modern technologies require materials with unusual combinations of properties that cannot be met by the conventional metal alloys, ceramics, and polymeric materials. Material property combinations and ranges have ...
New Approach: Waste Materials as Sorbents for Arsenic Removal from Water
(Journal of Environmental Engineering, 2010)
The sorption of inorganic arsenic species (arsenite and arsenate) from aqueous solutions onto steel-mill waste and waste filter sand, under neutral conditions, was investigated in this study. Additionally, the steel-mill ...
Hydrogels of N-isopropylacrylamide copolymers with controlled release of a model protein
(Elsevier Science Bv, Amsterdam, 2010)
Temperature- and pH-sensitive hydrogels, based on N-isopropylacrylamide (NiPAAm) and itaconic acid (IA), were synthesized by free radical crosslinking copolymerization in the presence of lipase from Candida rugosa. The ...
