High-performance hydrogen evolution electrocatalysis using proton-intercalated TiO2 nanotube arrays as interactive supports for Ir nanoparticles
(Royal Soc Chemistry, Cambridge, 2020)
Developing ultraefficient electrocatalytic materials for the hydrogen evolution reaction (HER) with low content of expensive platinum group metals (PGMs) via low-energy-input procedures is the key to the successful ...
When a Palearctic bacterium meets a Nearctic insect vector: Genetic and ecological insights into the emergence of the grapevine Flavescence doree epidemics in Europe
(Public Library Science, San Francisco, 2020)
Author summary Since the first outbreaks, Flavescence doree epidemics had been associated to the introduction of the North American leafhopper vector Scaphoideus titanus. We hereby show that the associated phytoplasma ...
Fractality and Self-organization in the Orthodox Iconography
(Wiley-Hindawi, London, 2016)
The authors consider the Orthodox iconography of Byzantine style aimed at examining the existence of complex behavior and fractal patterns. It has been demonstrated that fractality in icons is manifested as two types-descending ...
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 ...
Core-shell carbon fiber"Co1.5Mn1.5O4 mesoporous spinel electrode for high performance symmetrical supercapacitors
(Elsevier, Amsterdam, 2020)
We report a mesoporous composite system consisting of carbon fiber cores surrounded with Co1.5Mn1.5O4 spinel nanocrystal shells, synthesized by a simple two-step process involving single-nozzle co-electrospinning and ...
Microstructural evolution and electric properties of mechanically activated BaTiO3 ceramics
(Elsevier Sci Ltd, Oxford, 2007)
Ceramic materials with a perovskite related structures such as non-doped and doped barium titanate ceramics are attracting much interest for their application as capacitor dielectrics, resistors, thermal sensors, etc. Since ...
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 ...
Flooding modifies the genotoxic effects of pollution on a worm, a mussel and two fish species from the Sava River
(Elsevier, Amsterdam, 2016)
Extreme hydrological events, such as water scarcity and flooding, can modify the effect of other stressors present in aquatic environment, which could result in the significant changes in the ecosystem functioning. Presence ...
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 ...
