The electrical properties of chemically obtained barium titanate improved by attrition milling
(Springer, New York, 2013)
Barium titanate ceramics were prepared using the nanopowder resulting from a polymeric precursor method, a type of modified Pechini process. The obtained nanopowder was observed to agglomerate and in order to de-agglomerate ...
Low frequency noise characteristics of BaTiO3-NiFe2O4 composites at phase transition
(Institute of Electrical and Electronics Engineers Inc., 2015)
In this work we present detailed investigation of low frequency noise characteristics of BaTiO3-NiFe2O4 ceramic composites of different percentage of NiFe2O4. At the particular temperatures (that gets under the broad maximum ...
The modification of structural and optical properties of nano- and submicron ZnO powders by variation of solvothermal syntheses conditions
(Springer, Dordrecht, 2014)
Nano- (30-60 nm) and submicron (100-350 nm) ZnO particles were synthesized using solvothermal method at 200 degrees C from an ethanolic solution of zinc acetate dihydrate, applying different reaction conditions, i.e., pH ...
Soybean hull peroxidase immobilization on macroporous glycidyl methacrylates with different surface characteristics
(Springer, New York, 2014)
Soybean hull peroxidase (SHP, E.C. 1.11.1.7) was immobilized by a glutaraldehyde and periodate method onto series of macroporous copolymers of glycidyl methacrylate (GMA) and ethylene glycol dimethacrylate (EGDMA), ...
Decomposition of Complex Fluorescence Spectra Containing Components with Close Emission Maxima Positions and Similar Quantum Yields. Application to Fluorescence Spectra of Proteins
(Springer/Plenum Publishers, New York, 2013)
Despite of widely application of multivariate analysis in chemometrics, problem of resolving closely positioned components in the fluorescence spectra remained unsolved, thus limiting the usage of fluorescence spectroscopy ...
Review of sterlet (Acipenser ruthenus L. 1758) (Actinopterygii: Acipenseridae) feeding habits in the River Danube, 1694-852 river km
(Taylor & Francis Ltd, Abingdon, 2015)
The aim of this work is to present the variation in the sterlet's (Acipenser ruthenus L. 1758) diet along the course of the River Danube, from 1694 to 852 river km. The diet of sterlet mostly comprised 12 bottom fauna taxa. ...
Further in vitro Evaluation of Antimicrobial Activity of the Marine Sesquiterpene Hydroquinone Avarol
(Bentham Science Publ Ltd, Sharjah, 2014)
This work extends in vitro screening of antimicrobial activity of the sesquiterpene hydroquinone avarol, a main secondary metabolite of the Mediterranean sponge species Dysidea avara. The antimicrobial activity was in part ...
In vitro evaluation of antimicrobial activity of the freshwater sponge Ochridaspongia rotunda (Arndt, 1937)
(Taylor & Francis Ltd, Abingdon, 2014)
The antimicrobial activity of five crude extracts (aqueous, methanol, ethyl acetate, acetone and methylene chloride) of the freshwater sponge Ochridaspongia rotunda (Arndt, 1937) was evaluated in vitro by using microdilution ...
Fluorescence lifetime imaging of lignin autofluorescence in normal and compression wood
(Wiley-Blackwell, Hoboken, 2013)
Wood cell walls fluoresce as a result of UV and visible light excitation due to the presence of lignin. Fluorescence spectroscopy has revealed characteristic spectral differences in various wood types, notably normal and ...
A universal fluid cell for the imaging of biological specimens in the atomic force microscope
(Wiley-Blackwell, Hoboken, 2013)
Recently, atomic force microscope (AFM) manufacturers have begun producing instruments specifically designed to image biological specimens. In most instances, they are integrated with an inverted optical microscope, which ...
