LaMO3 (M = Mg, Ti, Fe) perovskite type oxides: Preparation, characterization and catalytic properties in methane deep oxidation
(Elsevier, 2008)
Two new series of perovskite-type oxides LaMO3 (M = Mg, Ti, Fe) with different ratio Mg/Fe (MF) and Ti/Fe (TF) in the B cation site were prepared by annealing the precursor, obtained by the mechanochemical activation (MCA) ...
Combined effects of antimony and sodium diethyldithiocarbamate on soil microbial activity and speciation change of heavy metals. Implications for contaminated lands hazardous material pollution in nonferrous metal mining areas
(Elsevier, 2018)
The combined effects of antimony (Sb) and sodium diethyldithiocarbamate (DDTC), a common organic flotation reagent, on soil microbial activity and speciation changes of heavy metals were investigated for the first time. ...
Initial corrosion protection of Zn-Mn alloys electrodeposited from alkaline solution
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
The effects of a deposition current density (c.d.) on the corrosion behaviour of Zn-Mn alloy coatings, deposited from alkaline pyrophosphate solution, were investigated by atomic absorption spectrophotometry (AAS), X-ray ...
Influence of temperature and dopant concentration on structural, morphological and optical properties of nanometric Ce1-xErxO2-delta (x=0.05-0.20) as a pigment
(Elsevier Sci Ltd, Oxford, 2015)
Ceramic pigments based on cerium oxide were synthesized by self-propagating room temperature method and their color properties were assessed from the viewpoint of potential environmentally nontoxic pink pigments. Thermal ...
Decolorization of reactive textile dyes using water falling film dielectric barrier discharge
(Elsevier, 2011)
Decolorization of reactive textile dyes Reactive Black 5, Reactive Blue 52, Reactive Yellow 125 and Reactive Green 15 was studied using advanced oxidation processes (AOPs) in a non-thermal plasma reactor, based on coaxial ...
Silver incorporation on viscose and cotton fibers after air, nitrogen and oxygen DBD plasma pretreatment
(Springer, Dordrecht, 2013)
Dielectric barrier discharge (DBD) pretreatments in air, nitrogen and oxygen plasma of viscose and cotton fabrics with subsequent immobilization of silver were studied. Surface activation of treated fibers was evaluated ...
The effect of diffusion on the impulse response of RCE detector
(IEEE Photonics Technology Letters, 2001)
We present a theory which demonstrates how the diffusion of photogenerated carriers affects the impulse response of a resonant-cavity enhanced photodetector (RCE). Analytic expressions for carrier densities and short-circuit ...
Parenchyma cell wall structure in twining stem of Dioscorea balcanica
(Springer, Dordrecht, 2017)
Anatomical adaptation of liana plants includes structural changes in cell walls of different tissues: fibers, vessel elements and tracheids. However, the contribution of parenchyma cells to stem twining in liana plants is ...
Assessment of the contamination of riparian soil and vegetation by trace metals - A Danube River case study
(Elsevier, 2016)
The aim of this study was to assess the spatial distribution of arsenic and heavy metals (Cd, Cr, Cu Hg, Ni, Pb and Zn) in a riparian area influenced by periodical flooding along a considerable stretch of the Danube River. ...
Organic Rankine Cycle system performance targeting and design for multiple heat sources with simultaneous working fluid selection
(Elsevier Sci Ltd, Oxford, 2017)
This work presents a systematic approach toward the design of Organic Rankine Cycles (ORC) for the generation of power from multiple heat sources available at different temperature levels. The design problem is approached ...
