Alkali-Aggregate Reactions in Concrete
(Atlantis Press, 2016)
In most concretes, aggregates are more or less chemically inert. However, some aggregates react with the alkali hydroxides in concrete, causing expansion and cracking over a period of many years. This alkali-aggregate ...
Intergranular properties and structural fractal analysis of BaTiO 3-ceramics doped by rare earth additives
(Hoboken, NJ : John Wiley & Sons, 2011)
Ferroelectric BaTiO3 as one of the most important ceramics materials in electronic, used on wide range of applications, can be modified with various dopant ions. In this paper, the influence of Er2O 3, Yb2O3, Ho2O3 and ...
Hydroxyapatite sintering in the presence of LiFePO4
(Belgrade : Materials Research Society of Serbia, 2014)
Sintering of hydroxyapatite attracts attention for decades with the final aim to obtain reliable materials for bio-applications. Various kind of sintering techniques as well as sintering additives were investigated to ...
Arsenic removal by magnetite-loaded amino modified nano/microcellulose adsorbents: Effect of functionalization and media size
(Elsevier, 2018)
Comparative adsorption study related to benefits of parent media size, i.e. microfibrillated cellulose (MC) versus nanocellulose (NC) support, for the preparation of magnetite (MG) based high performance adsorbent for ...
Macro and Micro-Scale Features of Thermoelectric PbTe (Br, Na) Systems: Micro-FTIR Spectroscopy, Micro-Seebeck Measurements, and SEM/EDX Observations
(Springer, 2014)
In this work, n-type and p-type PbTe doped with Br and Na, respectively, were thoroughly examined to determine the effect of the dopant on microstructure. Macro and micro homogeneity of the samples were studied by means ...
Thermal and mineralogical characterization of loess heavy clays for potential use in brick industry
(Elsevier, 2014)
This paper describes a study of 11 selected samples of loess soil from Serbia, by using differential scanning calorimetry, simultaneously with thermogravimetry and its differential calculation, known as simultaneous thermal ...
Enzymatic Synthesis of Aliphatic Esters of Phenolic Acids and Evaluation of Their Antioxidant Properties
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2012)
The esterification activity of the commercial immobilized lipase CALB towards cinnamic acids and its derivative has been studied. Using cinnamic acid as substrate, the reaction rate constants (1.95 h-1 mM-1 for ethanol and ...
Advanced Optimization of Heavy Clay Products Quality by Using Artificial Neural Network Model
(Belgrade : Serbian Ceramic Society, 2014)
The effects of firing temperature (800–1100°C), chemical composition (expressed in terms of the content of major oxides - SiO2, Al2O3, Fe2O3, CaO, MgO, Na2O, K2O, MnO and TiO2), as well as several shape formats of laboratory ...
The influence of m-aminobenzoic acid on electrochemical synthesis and behavior of poly(aniline-co-(m-aminobenzoic acid)
(Springer, Dordrecht, 2017)
Poly(aniline-co-(m-aminobenzoic acid)) was synthesized electrochemically at graphite electrode under galvanostatic conditions. Aqueous electrolyte for synthesis was consisted of HCl and different amount of aniline and ...
Assessment of Spasticity by a Pendulum Test in SCI Patients Who Exercise FES Cycling or Receive only Conventional Therapy
(IEEE, 2018)
Increased muscle tone and exaggerated tendon reflexes characterize most of the individuals after a spinal cord injury (SCI). We estimated seven parameters from the pendulum test and used them to compare with the Ashworth ...
