Isopiestic determination of the osmotic and activity coefficients of {yK(2)HPO(4) + (1-y)KH2PO4}(aq) at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2020)
Isopiestic measurements have been made at 55 compositions of the {yK(2)HPO(4) + (1 - y)KH2PO4}(aq) system at T = (298.15 +/- 0.01) K, 11 for each of the limiting binary solutions and 33 for mixture compositions at K2HPO4 ...
Structurally and surface-modified alumina particles as a reinforcement in polyester-based composites with an improved toughness
(Springer, New York, 2020)
Commercial gamma - Al2O3 particles, Al2O3 n, and synthesized Al2O3 doped with iron oxide (Al2O3 Fe) were used as reinforcements to enhance the toughness of an unsaturated polyester resin (UPR). Alumina modification with ...

Stability of TEMPO-oxidized cotton fibers during natural aging
(Elsevier Sci Ltd, Oxford, 2020)
Stability of cotton fibers oxidized by the 2,2,6,6-tetramethylpiperidine-1-oxy radical (TEMPO)-mediated system during natural aging was monitored; the oxidized and five-year-aged fibers were characterized in terms of ...
Numerical determination and experimental validation of the fracture toughness of welded joints
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Most of the serious weldment failures lead to catastrophic consequences in terms of damage of other equipment, loss of production, and risks to workers' health and safety. Hence, there is motivation to find margin between ...
Recovery of bioactive molecules from Hypericum perforatum L. dust using microwave-assisted extraction
