Spectroscopic study of spinel ZnCr2O4 obtained from mechanically activated ZnO-Cr2O3 mixtures
(Elsevier Sci Ltd, Oxford, 2007)
A mixture of starting ZnO and Cr2O3 powders in equimolar quantities was mechanically activated by grinding using a high energy vibro-mil I for 0, 40 and 80 min. The spinet ZnCr2O4 was prepared from activated mixtures by a ...
Immobilization of cesium with alkali-activated blast furnace slag
(Elsevier, Amsterdam, 2020)
Alkali-activated binders (AABs), as a promising alternative to Portland cement, are now being used on a commercial scale in various applications around the world, including hazardous and radioactive waste immobilization. ...
The characterization of the barium titanate ceramic powders prepared by the Pechini type reaction route and mechanically assisted synthesis
(Elsevier Sci Ltd, Oxford, 2010)
BaTiO3 ceramic powders were prepared by a complex method based on the Pechini type reaction route and mechanically assisted synthesis. In both ways BaTiO3 ceramics were sintered after 120 min on 1300 degrees C without ...
Physical and mechanical properties of hemp fibre reinforced alkali-activated fly ash and fly ash/slag mortars
(Elsevier Sci Ltd, Oxford, 2020)
Two alkali-activated mortars with different solid prime materials were analysed. The first mortar contained fly ash, had lower density, higher water absorption, lower compactness, lower compressive strength, similar flexural ...
Low ascorbic acid in the vtc-1 mutant of arabidopsis is associated with decreased growth and intracellular redistribution of the antioxidant system
(Oxford Univ Press Inc, Cary, 2001)
Ascorbic acid has numerous and diverse roles in plant metabolism. We have used the vtc-1 mutant of Arabidopsis, which is deficient in ascorbate biosynthesis, to investigate the role of ascorbate concentration in growth, ...
Far infrared properties of PbTe doped with cerium
(Elsevier Science Sa, Lausanne, 2007)
Single crystal samples of lead telluride doped with cerium were made using the Bridgman method. Far infrared reflectivity spectra in the temperature range from 10 to 300K are presented. The experimental data were numerically ...

External sulfate attack on alkali-activated fly ash-blast furnace slag composite
(Elsevier Sci Ltd, Oxford, 2017)
Reliable durability testing of alkali-activated binders, which might serve as a basis for the prediction of long-term field performance, is one of the main challenges towards broader commercial applications of AAB. This ...
Further in vitro biological activity evaluation of amino-, thio- and ester-derivatives of avarol
(Taylor & Francis Ltd, Abingdon, 2016)
The acetylcholinesterase inhibitory and/or antitumour activities of amino-, thio- and ester-derivatives of avarol selected were evaluated for the first time at in vitro conditions. Avarol-3',4'-dithioglycol (1) and ...
Novel Pt catalyst on ruthenium doped TiO2 support for oxygen reduction reaction
(Elsevier, Amsterdam, 2013)
Ruthenium doped titanium oxide support was synthesized. The support was characterized by BET (Brunauer, Emmett, Teller) and X-ray diffraction techniques (XRD). Determined specific surface area was 41 m(2) g(-1). XRD revealed ...
