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 ...
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 ...
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 ...
Evaluation of stability and functionality of BaCe1-xInxO3-delta electrolyte in a wider range of indium concentration
(Springer, New York, 2022)
The properties of BaCe1-xInxO3-delta (x = 0.05, 0.10, 0.15, 0.20, 0.25, 0.30, 0.35, and 0.40) as proton conducting electrolyte are examined. The dense electrolyte is formed after sintering at 1300 degrees C for 5 h in air. ...
Influence of silicon on polymerization process during lignin synthesis. Implications for cell wall properties
(Elsevier B.V., 2022)
Silicon (Si) is considered a beneficial element for plants, mostly accumulating in cell walls, where its location and content are primed by the chemistry and structure of lignin. It is unrevealed how Si interacts with the ...
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 ...
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 ...
Chitosan and pectin-based films and coatings with active components for application in antimicrobial food packaging
(Elsevier Science Sa, Lausanne, 2021)
This investigation was aimed to develop films and coatings based on natural biopolymers and active components, with physicochemical and functional properties for application in antimicrobial packaging. Biopolymer films ...
Interactions of Silicon With Essential and Beneficial Elements in Plants
(Frontiers Media Sa, Lausanne, 2021)
Silicon (Si) is not classified as an essential element for plants, but numerous studies have demonstrated its beneficial effects in a variety of species and environmental conditions, including low nutrient availability. ...
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 ...
