Welded joint geometry effect on fatigue crack growth resistance in different metallic materials
(International Journal of Fatigue, 2021)
Fatigue crack growth through different welded joint regions was investigated, in terms of welded joint geometry and fatigue crack position. In the first phase of investigation, numerical simulation of crack growth in a ...
Mechanical and thermal properties of UV cured mixtures of linear and hyperbranched urethane acrylates
(Elsevier Science Sa, Lausanne, 2012)
The properties of urethane acrylate resin mixtures based on the linear and hyperbranched aliphatic polyesters were examined. Linear polyester was synthesized from neopentil glycol and adipic acid. Hyperbranched polyester ...
Isopiestic determination of the osmotic and activity coefficients of the {yKBr + (1-y)K2HPO4}(aq) system at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2013)
The molality-based osmotic coefficients of aqueous mixtures of KBr and K2HPO4 have been measured at T = (298.15 +/- 0.01) K by the isopiestic method at KBr ionic strength fractions y = (0.18328, 0.38241, 0.58031, 0.79186, ...
Regenerated Cellulose Fiber Functionalization by Two-step Oxidation Using Sodium Periodate and Sodium Chlorite - Impact on the Structure and Sorption Properties
(Korean Fiber Society, 2021)
Successful conversion of cellulose hydroxyl (OH) to carboxyl (COOH) groups is the goal of many modification procedures since COOH groups enhance the polarity of the fibers' surface and can be used for further fibers' ...
Porous acicular mullite obtained by controlled oxidation of waste molybdenum disilicide
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
Porous acicular mullite was fabricated by using waste MoSi2 heating element and Al2O3. Careful calcination of the pulverized heating element led to the formation of a mixture of MoO3 and amorphous SiO2. This mixture was ...
On the role of aniline oligomers on the corrosion protection of mild steel
(Elsevier Science Sa, Lausanne, 2014)
Corrosion of the mild steel electrode with electrochemically formed aniline oligomers coating in 3% NaCl has been investigated by the means of electrochemical techniques and UV-vis spectroscopy. It has been shown that ...
Supercritical fluid extraction of curry flowers, sage leaves, and their mixture
(Elsevier, Amsterdam, 2013)
Yield and composition of curry flower (Helichrysum italicum) and sage leaves (Salvia officinalis) extract obtained by supercritical CO2 extraction (SFE) at 15 MPa and 40 degrees C were analyzed and compared to composition ...
Functionalization of textile materials with silver nanoparticles
(Springer, New York, 2013)
Nanoparticles gained much scientific attention in the past decade due to their specific surface chemistry and properties which are significantly different from that of the corresponding bulk materials. Silver nanoparticles ...
A New Approach in Regression Analysis for Modeling Adsorption Isotherms
(Hindawi Ltd, London, 2014)
Numerous regression approaches to isotherm parameters estimation appear in the literature. The real insight into the proper modeling pattern can be achieved only by testing methods on a very big number of cases. Experimentally, ...
The mathematics of modelling the supercritical fluid extraction of essential oils from glandular trichomes
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
This article deals with mathematical tools used for solving equations of the improved mathematical model on the micro-scale for the process of supercritical fluid extraction of essential oils from glandular trichomes. ...
