Improved compressive strength of alkali activated slag upon heating
(Elsevier Science Bv, Amsterdam, 2014)
This paper presents a study on thermal stability of alkali activated slag (AAS) prepared from electric arc furnace slag (EAFS) using a mixture of alkaline sodium hydroxide and sodium silicate solutions. The samples were ...
Platinum deposition from hydrogen-ion beam irradiated solid precursor
(Materials Letters, 2011)
We report a particular method of Pt/glassy carbon (GC) surface formation, based on a 15 key H(+/-) ion beam irradiation of thin H(2)PtCl(6)xnH(2)O layer placed over the GC surface. Hydrogen-ion beam irradiation provided ...
Mechanochemical synthesis of nanocrystalline titanium monoxide
(Elsevier, 2008)
Nanocrystalline cubic titanium monoxide, TiOx (0.92 < x < 1.19), with mean crystallite size of ≈ 6 nm, was synthesized by mechanochemical treatment of Ti and TiO2 (rutile) powder mixtures with molar ratios of 1:1, ...
Design of novel multifunctional Oxaprozin delivery system based on dual-sensitive poly(2-hydroxypropyl acrylate/itaconic acid) hydrogels
(Elsevier Science Bv, Amsterdam, 2015)
Series of novel dual-sensitive poly(2-hydroxypropyl acrylate/itaconic acid) hydrogels were designed as multifunctional drug delivery system which can provide several advantages including drug protection, self-regulated ...
Cavitation damage of the medium carbon steel: Implementation of image analysis
(Elsevier Science Bv, Amsterdam, 2008)
Cavitation damage of the medium carbon steel was performed using the modified vibratory cavitation test set up. Erosion rates were measured by analytical method. The morphology of damage under cavitation action was determined ...
Thermal properties of PS/TiO2 nanocomposites obtained by in situ bulk radical polymerization of styrene
(Elsevier Science Bv, Amsterdam, 2009)
TiO2 nanoparticles. surface modified with 6-palmitate ascorbic acid, were incorporated in polystyrene (PS) by in situ bulk radical polymerization of styrene using 2,2'-azobisisobutyronitrile as initiator. The molar mass ...
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 ...
Silicon-doped biphasic alpha-calcium-phosphate/hydroxyapatite scaffolds obtained by a replica foam method using uniform pre-annealed spherical particles
(Elsevier Science Bv, Amsterdam, 2012)
In this study, spherical particles of hydroxyapatite (HA) and alpha-tricalcium phosphate (alpha-Ca-3(PO4)(2): alpha-TCP) doped with different amounts of silicon were used for the preparation of scaffolds. The scaffolds ...
Copper nanoparticles with high antimicrobial activity
(Elsevier Science Bv, Amsterdam, 2014)
Copper (Cu) hydrosol containing small nanoparticles (NPs) (similar to 5 nm) with narrow size distribution were used to investigate antimicrobial activity toward representative microorganisms of public concern (Escherichia ...
Quantification of deformation response at cyclic compression of polymer fibrous systems
(Elsevier Science Bv, Amsterdam, 2014)
The difficulty in qualitative evaluation of deformation properties of polymer fibrous assemblies lies in the fact that these materials differ from materials such as wood, concrete, steel, etc., as a consequence of the ...
