Influence of picosecond laser pulses on the microstructure of austenitic materials
(Springer, New York, 2011)
We investigate samples of austenitic materials - stainless steel and iron-based superalloy - which are widely used at high temperatures and pressures. The samples were exposed to Nd(3+):YAG laser pulses with a wavelength ...
Electrospun Poly(vinylbutyral)/silica Composite Fibres for Impregnation of Aramid Fabrics
(Materiale Plastice, 2014)
The poly (vinyl butyral)/silica (PVB/SiO2) composite fibers were produced by the electrospinning process. The experiments were performed with the PVB solution in concentration of 10 wt.% where ethanol was used as the ...
QSAR characterization of new synthesized hydantoins with antiproliferative activity
(Wiley, Hoboken, 2019)
Hydantois have been identified as constituents of a number of pharmacologically active molecules. In the present study, we have examined in vitro antiproliferative activity against human colon cancer cell lines HCT-116 of ...
Microhardness of decorative gold coatings obtained from gold complex based on mercaptotriazole: Comparison with cyanide
(Carl Hanser Verlag, Munich, 2016)
The aim of this work was to investigate the effects of current density, temperature, pH and concentration of ethyl-hexilsulfonate additive on the microhardness of electrochemically deposited gold decorative coatings obtained ...
Thermodynamics of mixed and pure aqueous solutions of K2HPO4 at T=298.15 K
(Maik Nauka/Interperiodica/Springer, New York, 2015)
Experimental results on isopiestic measurements for three ternary aqueous solutions of K2HPO4 with KCl, KBr, and KNO3 at T = 298.15 K were modeled with the Clegg-Pitzer-Brimblecombe equation based on mole-fraction-composition ...
Isopiestic Determination of the Osmotic and Activity Coefficients of the {yNa(2)HPO(4) + (1-y)K2HPO4}(aq) System at T=298.15 K
(Springer/Plenum Publishers, New York, 2016)
Isopiestic measurements have been made for aqueous mixtures of Na2HPO4 and K2HPO4 at T = (298.15 +/- 0.01) K, at Na2HPO4 ionic strength fractions y = (0.2023, 0.4060, 0.6027, 0.8007, and 1), using KCl(aq) as the reference ...
Adsorption kinetics of polyethersulfone membrane-supported hydrogels
(Desalination Publ, Hopkinton, 2018)
This study presents the route for preparation of the membrane-supporting materials with good mechanical behavior and adsorption properties that provide functionality and are easy to use in various environments. Polyethersulfone ...
Adventitious organogenesis via intermediate callus formation in representatives of Prunus, Pyrus and Rubus genera
(Ars Docendi, Bucharest, 2014)
The paper presents evaluation of the influence of 30 combinations of plant growth regulators (PGRs) on induction of adventitious organogenesis from leaves of in vitro propagated shoots in 5 genotypes: sour cherry 'Cacanski ...
Influence of surface modification to mechanical and thermal properties of nanomodified acrylic dental resin
(Inst Materials Physics, Bucharest, 2018)
This paper investigated the processing and characterization of dental nanocomposites based on poly(methyl methacrylate) (PMMA) matrix reinforced with zirconium dioxide (ZrO2) nanoparticles were prepared by in-situ free ...
Unusual growth of pollen tubes in the ovary of quince (cydonia oblonga mill.)
(Acta Scientiarum Polonorum, Hortorum Cultus, 2017)
This paper presents the results of a three-year research (2010-2012) of unusual growth of pollen tubes in the ovary in eight cultivars of quince in two pollination variants (self-pollination and open-pollination). Unusual ...
