Structural, morphological and textural properties of iron manganite (FeMnO3) thick films applied for humidity sensing
(Elsevier, Amsterdam, 2020)
Iron manganite (FeMnO3) powder with a cubic (bixbyite, Ia (3) over bar) crystal structure was obtained by a solid state reaction. Thick film paste (powder + organic vehicles) was screen printed on alumina substrate with ...
Experimental photoacoustic observation of the photogenerated excess carrier influence on the thermoelastic response of n-type silicon
(Amer Inst Physics, Melville, 2020)
Based on the experimental and theoretical signals of an open photoacoustic cell operating with modulation frequencies from 20Hz to 20kHz, a significant contribution of photogenerated excess carriers on the thermal and ...
Complex permittivity and complex permeability characteristics of Co-Ti doped barium strontium hexaferrite/paraffin wax composites for application in microwave devices
(Springer Heidelberg, Heidelberg, 2020)
The microwave characteristics of composites prepared from Ba0.5Sr0.5CoxTixFe(12-2x)O19/paraffin wax with 10% and 20% volume fraction of ferrite powder in wax have been examined in the test frequency range of 0.13-4 GHz. ...
Evaluation of tansy essential oil as a potential "green" alternative for gypsy moth control
(Springer Heidelberg, Heidelberg, 2020)
The development of "green" alternatives to chemical pesticides could play a crucial role in integrated pest management (IPM). Their use is considered either as a substitution for or in addition to hazardous synthetic ...
Coprinus comatusfiltrate extract, a novel neuroprotective agent of natural origin
(Taylor & Francis Ltd, Abingdon, 2020)
In vitroacetylholinesterase (AChE) inhibitory activity of an autochthonous sample of the mushroomCoprinus comatus(encompassing fruiting body FB, mycelia M and filtrate F from the submerged cultivation) was the subject of ...
Central nervous system-infiltrated immune cells induce calcium increase in astrocytes via astroglial purinergic signaling
(Wiley, Hoboken, 2020)
Interaction between autoreactive immune cells and astroglia is an important part of the pathologic processes that fuel neurodegeneration in multiple sclerosis. In this inflammatory disease, immune cells enter into the ...
Effects of strontium doping on microstructure and functional properties of solution-derived potassium sodium niobate thin films
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad, 2020)
The effects of strontium doping (0-2 mol%) on structure, microstructure and functional properties of potassium sodium niobate (KNN) thin films deposited on Pt(111)/TiOy/SiO2/Si substrates were investigated. Incorporation ...
Nanocrystalline Zn2SnO4/SnO2: Crystal structure and humidity influence on complex impedance
(Springer, Dordrecht, 2020)
Nanocrystalline Zn2SnO4/SnO2 powder was obtained by a solid state reaction of ZnO and SnO2 nanopowders mixed in the molar ratio 1:1. The phase composition of the obtained powder was studied by XRD and Raman spectroscopy, ...
Isopiestic Determination of Osmotic and Activity Coefficients of the {yNaH(2)PO(4) + (1-y)Na2HPO4}(aq) System at T=298.15 K
(Amer Chemical Soc, Washington, 2020)
Isopiestic measurements have been made for aqueous solutions of the common sodium cation mixtures of NaH2PO4 and Na2HPO4 at T = 298.15 +/- 0.01 K, at NaH2PO4 ionic strength fractions y = (0, 0.24851, 0.49862, 0.74544, and ...
Isopiestic determination of the osmotic and activity coefficients of {yK(2)HPO(4) + (1-y)KH2PO4}(aq) at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2020)
Isopiestic measurements have been made at 55 compositions of the {yK(2)HPO(4) + (1 - y)KH2PO4}(aq) system at T = (298.15 +/- 0.01) K, 11 for each of the limiting binary solutions and 33 for mixture compositions at K2HPO4 ...
