Microstructural, Thermoelectric and Mechanical Properties of Cu Substituted NaCo2O4
(MDPI, 2022)
Polycrystalline samples of NaCo2−xCuxO4 (x = 0, 0.01, 0.03, 0.05) were obtained from powder precursors synthesized by a mechanochemically assisted solid-state reaction method (MASSR) and a citric acid complex method (CAC). ...
Mechanochemical synthesis of bismuth ferrite
(Univerzitet u Beogradu - Tehnički fakultet u Boru, Beograd, 2013)
A powder mixture of Bi2O3 and Fe2O3 was mechanically treated in a planetary ball mill in an air from 30 to 720 minutes. It was shown that the mechanochemical formation of BiFeO3 (BFO) phase was initiated after 60 min 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 ...
Stolbur Phytoplasma Transmission to Maize by Reptalus panzeri and the Disease Cycle of Maize Redness in Serbia
(Amer Phytopathological Soc, St Paul, 2009)
Maize redness (MR), induced by stolbur phytoplasma ('Candidatus Phytoplasma solani', subgroup 16SrXII-A), is characterized by midrib, leaf, and stalk reddening and abnormal ear development. MR has been reported from Serbia, ...
Morphological and crystallographic characteristics of electrodeposited lead from a concentrated electrolyte
(Royal Soc Chemistry, Cambridge, 2013)
Electrodeposition of lead from a concentrated nitrate solution was examined by scanning electron microscopy (SEM) and by X-ray diffraction (XRD) analysis of the obtained powder particles. Single crystals of the (111) ...
Silicon Improves the Production of High Antioxidant or Structural Phenolic Compounds in Barley Cultivars under Aluminum Stress
(MDPI, Basel, 2019)
Aluminum (Al) toxicity is one of the main growth and yield limiting factors for barley grown on acid soils. Silicon (Si) ameliorates Al toxicity as well as it promotes the phenolic compounds production that have antioxidant ...
Excitation of guided waves in materials with negative refraction
(Elsevier, 2008)
We study, both analytically and numerically, electromagnetic beam transmission through a layered structure that includes a waveguide slab of metamaterial with negative refraction. The resonant excitation of the leaky guided ...
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 ...
