Antiferromagnetism and heat capacity of NaCo2-xCuxO4 ceramics
(Elsevier Sci Ltd, Oxford, 2017)
Polycrystalline samples of NaCo2-xCuxO4 (x=0, 0.01, 0.03 and 0.05) were synthesized in two different ways: 1) by a mechanochemically assisted solid-state reaction method (MASSR) and 2) by a citric acid complex method (CAC). ...
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 ...
Immobilization of hexavalent chromium by fly ash-based geopolymers
(Elsevier Sci Ltd, Oxford, 2017)
In this paper the immobilization of hexavalent chromium (Cr (VI)) by fly ash (FA)-based geopolymers was investigated, depending on FA characteristics, mechanical activation of FA, geopolymer synthesis conditions and ...
Dielectric and ferroelectric properties of Ho-doped BiFeO3 nanopowders across the structural phase transition
(Elsevier Sci Ltd, Oxford, 2017)
We have studied Ho-doped BiFeO3 nanopowders (Bi1-xHoxFeO3, x = 0-0.15), prepared via sol-gel method, in order to analyse the effect of substitution-driven structural transition on dielectric and ferroelectric properties ...
Transformation of Cs-exchanged clinoptilolite to CsAlSi5O12 by hot-pressing
(Elsevier Sci Ltd, Oxford, 2017)
Dense CsAlSi5O12 was successfully obtained by hot pressing of Cs-exchanged clinoptilolite at 900 degrees C. Simultaneous application of high temperature and mechanical pressure allowed formation of CsAlSi5O12 at temperature ...
Antiradical activity of delphinidin, pelargonidin and malvin towards hydroxyl and nitric oxide radicals: The energy requirements calculations as a prediction of the possible antiradical mechanisms
(Elsevier Sci Ltd, Oxford, 2017)
Naturally occurring flavonoids, delphinidin, pelargonidin and malvin, were investigated experimentally and theoretically for their ability to scavenge hydroxyl and nitric oxide radicals. Electron spin resonance (ESR) ...
Parenchyma cell wall structure in twining stem of Dioscorea balcanica
(Springer, Dordrecht, 2017)
Anatomical adaptation of liana plants includes structural changes in cell walls of different tissues: fibers, vessel elements and tracheids. However, the contribution of parenchyma cells to stem twining in liana plants is ...
Silicon increases phosphorus (P) uptake by wheat under low P acid soil conditions
(Springer, Dordrecht, 2017)
Although silicon (Si) is known to improve plant growth under low phosphorus (P) conditions, the in planta mechanisms responsible for this effect are still unknown. Here, we investigated the role of Si on P uptake along ...
Enzymatic Profile of 'Willamette' Raspberry Leaf and Fruit Affected by Prohexadione-Ca and Young Canes Removal Treatments
(Amer Chemical Soc, Washington, 2017)
The influence of growth regulator prohexadione-Ca (ProCa) concurrently with young canes removal on the modification of photosynthetic pigments content and antioxidant enzymes (peroxidase, POD; catalase, CAT; polyphenol ...
Influence of tungsten doping on dielectric, electrical and ferroelectric behavior of BaBi4Ti4O15 ceramics
(Elsevier Science Sa, Lausanne, 2017)
The effect of tungsten (W6+) doping on modification of the structure, dielectric, ferroelectric and electrical properties of BaBi(4)Ti(4-x)WxO(15) (BBTWx, x = 0, 0.03, 0.05 and 0.07) was investigated. The ceramic samples ...
