The structural, electrical and optical properties of spark plasma sintered BaSn1-xSbxO3 ceramics
(Elsevier Sci Ltd, Oxford, 2020)
Antimony doped barium-stannate dense ceramic materials were synthesized using spark plasma sintering technique out of mechanically activated precursor powders. The influence of various Sb concentrations (x = 0.00 - 0.10) ...
Significance of silicon uptake, transport, and deposition in plants
(Oxford Univ Press, Oxford, 2020)
Numerous studies have shown the beneficial effects of silicon (Si) for plant growth, particularly under stress conditions, and hence a detailed understanding of the mechanisms of its uptake, subsequent transport, and ...
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 ...
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 ...
Identification and first insights into the structure of chitin from the endemic freshwater demosponge Ochridaspongia rotunda (Arndt, 1937)
(Elsevier, Amsterdam, 2020)
Studies on the identification, properties and function of chitin in sponges (Porifera), which are recognized as the first multicellular organisms on Earth, continue to be of fundamental scientific interest. The occurrence ...
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. ...
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 ...
New inversion boundary structure in Sb-doped ZnO predicted by DFT calculations and confirmed by experimental HRTEM
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Today, ab-initio calculations are becoming a powerful tool to perform virtual experiments that have the capacity to predict and to reproduce experimentally observed non-periodic features, such as interfaces, that are ...
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 ...
Risk assessment of using fish from different types of reservoirs as human food - A study on European perch (Perca fluviatilis)
(Elsevier Sci Ltd, Oxford, 2020)
Concentrations of As, Cd, Cr, Cu, Hg, Pb, and Zn in sediment samples and muscle tissue of the European perch were analyzed using inductively-coupled plasma optical emission spectrometry (ICP-OES), with the aim to assess ...
