Dense and near-net-shape fabrication of Si3N4 ceramics
(Materials Science and Engineering A: Structural Materials Properties Microstructure and Processing, 2009)
With silicon nitride significant progress has been made in order to search for fully dense, strong, reliable structural ceramics to find wide use in applications at high temperatures which are allowing new and innovative ...
The influence of molecular orientation on the crosslinking/oxidative behaviour of iPP exposed to gamma radiation
(European Polymer Journal, 2009)
This paper presents a study of the influence of structural peculiarities, uniaxial orientation and fibrillar structure on the radiation-induced changes in iPP. For the purposes of this study, iPP was oriented via solid-state ...

CuZn superoxide dismutase in the hippocampus and brain cortex of rats exposed to various stress conditions
(Annals of the New York Academy of Sciences, 2005)
The CuZn superoxide dismutase (CuZnSOD) protein expression in hippocampus and brain cortex of Wistar male rats exposed to acute, chronic, or combined stress was followed by Western immunoblotting. The CuZnSOD was significantly ...
Synthesis under self-controlled reaction conditions: Reaction of tetraamminezinc(II) chloride with 3,5-dimethyl-1-thiocarboxamide pyrazole
(Journal of Organometallic Chemistry, 2007)
The trinuclear [Zn-3(Hdmpz)(2)(dmpz)(4)(NCS)(2)] complex (Hdmpz: 3,5-dimethylpyrazole) has been synthesized by the reaction of tetraamminezinc(II) chloride with 3,5-dimethyl-1-thiocarboxamidepyrazole. The ammonia evolving ...
Raman spectroscopy of Cd1-xMnxS quantum dots
(Journal of Physics. D: Applied Physics, 2005)
Powders consisting of 44 angstrom Cd1-xMnxS (x = 0; 0.05; 0.1; 0.15; 0.3) quantum dots (QDs) were synthesized using the colloidal chemistry method and characterized by Raman scattering measurements. The dominant Raman line ...
The effect of repeated physical exercise on hippocampus and brain cortex in stressed rats
(Annals of the New York Academy of Sciences, 2007)
Sensitivity of target cells to glucocorticoids is regulated by the expression of intracellular glucocorticoid receptor (GR), which mediates the effects of glucocorticoids. The level of GR and of its nuclear transporter ...
Distinct cytotoxic mechanisms of pristine versus hydroxylated fullerene
(Toxicological Sciences, 2006)
The mechanisms underlying the cytotoxic action of pure fullerene suspension (nano-C-60) and water-soluble polyhydroxylated fullerene [C-60(OH)(n)] were investigated. Crystal violet assay for cell viability demonstrated ...
Corrosion behavior and thermal stability of electrodeposited PANI/epoxy coating system on mild steel in sodium chloride solution
(Progress in Organic Coatings, 2006)
The corrosion behavior, sorption characteristics and thermal stability of epoxy coatings electrodeposited on mild steel (MS) and mild steel with electrochemically deposited polyaniline (PANI) film were investigated in 3% ...
