The Krajcinovic approach to model size dependent fracture in quasi-brittle solids
(Elsevier, 2014)
The failure in “quasibrittle” microstructural systems, occurring with no early warning, is a debated problem of great practical importance for the structural engineering community. Available models do not fully account for ...
Examination of the doping effects of samarium (Sm3+) and zirconium (Zr4+) on the photocatalytic activity of TiO2 nanofibers
(Elsevier, 2023)
Pure and samarium (Sm3+) - or zirconium (Zr4+)-doped TiO2 nanofibers were synthesized by electro-
spinning method followed by calcination at 500 °C for 1 h. As-spun fibers were smooth, straight and
continuous, whilst ...
Ordering effect of kinetic energy on dynamic deformation of brittle solids
(Elsevier, 2008)
The present study focuses on the plane strain problem of medium-to-high strain-rate loading of an idealized brittle material with random microstructure. The material is represented by an ensemble of “continuum particles” ...
Some Observations Regarding Stochasticity of Dynamic Response of 2D Disordered Brittle Lattices
(SAGE Publications, 2011)
It had been long recognized that the tensile strength of brittle materials
increases with increase of the loading rate. In the present article, a statistical
approach to rupture of a disordered 2D triangular truss lattice ...
Antioxidant and cell-friendly Fe2TiO5 nanoparticles for food packaging application
(Elsevier, 2022)
An emerging technology of active packaging enables prolongation of food shelf life by limiting the oxygen transfer and the reactivity of free radicals, which both destruct food freshness. In this work, Fe2TiO5 nanoparticles ...
(Chalcogen)semicarbazones and their cobalt complexes differentiate HL-60 myeloid leukaemia cells and are cytotoxic towards tumor cell lines
(RSC Publishing, 2017)
Cobaltcomplexeswithsemi-andthiosemicarbazonesof8-quinolinecarboxaldehydehavebeensynthesizedandcharacterizedbyX-raydiffractionanalysis.Thesenovelcomplexesandapreviouslysynthesized cobaltcomplexwithaselenium-basedselenosem ...
Effects of selected inorganic chemical activators on properties and hydration mechanism of high volume fly ash (HVFA) binders
(Elsevier Ltd., 2023)
Effects of Na2SO4, Na2CO3, and Na2SiO3 on setting time, compressive strength (up to 90 days), and hydration mechanism of binders with high volume (70 wt%, HVFA binders) of fly ash (FA) were investigated. Before chemical ...
Influence of acid-base equilibria on the rate of the chemical reaction in the advanced oxidation processes: Coumarin derivatives and hydroxyl radical
(Elsevier, 2023)
The decomposition and chemical manipulation of stable aromatic pollutants into less toxic products is an
important topic for wastewater management and natural water remediation. The mechanism of the Advanced
Oxidation ...
Electrical and sensing properties of indium-doped barium cerate
(Elsevier LtdTechna Group S.r.l., 2023)
Systematic analysis of electrical characteristics of BaCe0.75In0.25O3-δ (BCI25) sintered sample was performed in a
dry and a wet argon atmosphere in the 250 ◦C–700 ◦C temperature range. The water vapor sensing properties ...
What’s the rumpus? Resident temperate forest birds approach an unfamiliar neotropical alarm call across three continents
(The Royal Society, 2023)
Alarm signals have evolved to communicate pertinent threats to conspecifics,
but heterospecifics may also use alarm calls to obtain social information. In
birds, mixed-species flocks are often structured around focal ...
