On strain-rate sensitivity and size effect of brittle solids: transition from cooperative phenomena to microcrack nucleation
(Springer Nature, 2013)
An idealized brittle microscale system is subjected to dynamic uniaxial tension in the medium-tohigh
strain-rate range (˙ε ∈ [100 s−1, 1×107 s−1]) to investigate its mechanical response under constrained
spatial and ...
Impact fragmentation of nanoscale projectiles at ultrahigh striking velocities
(Springer Nature, 2015)
Molecular-dynamics simulations of the
classic Taylor experiment are performed to investigate
some general trends of impact fragmentation at ultrahigh
striking velocities. The striking velocities of flatended,
monocrystalline, ...
Further Remarks on Stochastic Damage Evolution of Brittle Solids Under Dynamic Tensile Loading
(SAGE Publications, 2011)
This article illuminates some general features and provides elementary
interpretations of the deformation, damage, and failure of brittle solids characterized
by very low fracture energy. The dynamic response of these ...
Modeling the effect of temperature on relative humidity sensing
(IEEE, 2023)
In this work we have established a mathematical function to model the influence of the ambient temperature, relative humidity and frequency on the change of impedance. The proposed empirical description is a combination ...
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 ...
Metal oxide nanoparticles for safe active and intelligent food packaging
(Elsevier Science London, London, 2021)
Background: Food safety and food security remain the major concern of consumers and the food industry. Bacterial contamination continues to be a crucial food safety issue. Smart packaging incorporates both active and ...
Trans-generational effect of cerium oxide-nanoparticles (nCeO2) on Chenopodium rubrum L. and Sinapis alba L. seeds
(CSIRO PUBLISHING, 2023)
Cerium oxide nanoparticles (nCeO2) are interesting nanomaterials due to their redox properties. Their wide application could result in unexpected consequences to environmental safety. Unlike acute toxicity, the trans-generational ...
Accumulation of metal trace elements in different body parts of terrestrial Roman snail Helix pomatia L., 1758 on three polluted sites in Serbia
(Springer, 2022)
Atmospheric pollution remains one of the growing concerns in the twenty-first century, with particular focus on metal trace elements (MTE) from anthropogenic sources, due to their adverse effects on biota. The concentration ...
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 ...
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 ...
