The main objective of this study was to characterize hemocytes found in circulation of the Black-scar oyster, Crassostrea iredalie . Hemolymp was collected from heart chamber and used for hemocyte characterization under a light microscopy. Histological technique was also used to investigate hemocyte characteristics in…

Magnetic nanoparticles (MNPs) synthesized by a co-precipitation method of Fe 2+ and Fe 3+ in basic solution were coated with poly[(methacrylic acid)-ran-(2-methacryloyloxyethyl phosphorylcholine)] (PMAMPC-MNPs) via a chelation between a carboxyl group of PMAMPC and an iron atom. Polymer concentration and chelation tim…
Vitrification is currently the world-wide treatment of choice for the disposition of high-level nuclear wastes. In glasses, radionuclides are atomistically bonded into the solid, resulting in a highly durable product, with borosilicate glasses exhibiting particularly excellent durability in water. Considering that was…
To solve the open circuit voltage limitation in Cu2ZnSn(SSe)4 further understanding of defects and the fundamental properties of the bulk material are needed. Although there are a number of literature reports of single crystals, the vast majority are made with a flux agent such as iodine which could potentially act as…
ZionSolutions is in the process of decommissioning the Zion Nuclear Power Plant. The site contains two reactor Containment Buildings, a Fuel Building, an Auxiliary Building, and a Turbine Building that may be contaminated. The current decommissioning plan involves removing all above grade structures to a depth of 3 fe…
There are various processes and techniques by which one can achieve well polished (highly reflective) and smooth, flat (low roughness) surfaces on a wide variety of materials. Historically, precision lapping processes were first applied to optical materials for the production of lenses for telescopes and microscopes.…
A coordination polymer, namely [Co-15(btc)(2,2'-bpy)(0.5)(2H(2)O)](n)(1) has been constructed hydrothermally using H(3)btc (H(3)btc=biphenyl-2,4,4-tricarboxylic acid), 2, 2'-bpy (2, 2'-bpy=2, 2'-bipyridine), and CoCl2 center dot 6H(2)O. The compound crystallizes in the monoclinic system, space group I2/a with a=1.774…
In this work was studied the development of structure/property correlations for new fluorophosphate glasses compositions: [80Ba(PO 3 ) 2 -20Al(PO 3 ) 3 ] 1-x [80BaF 2 -20AlF 3 ] x (0 ≤ x ≤ 40 -mol%).Most suitable techniques for the structural analysis in case of disordered and amorphous material are Nuclear Magnetic R…
New heat resistant methylphenylsiloxane resins produced by methyltriethoxysilane and oligophenylsilsesquioxane acidolysis were investigated. The synthesized resins are characterized by narrow molecular -mass distribution, higher thermal and thermal oxidative stability, reduced gelation period as compared to starting o…

Effect of length scales on microstructure evolution during Severe Plastic Deformation (SPD) was studied using orthogonal machining as a test of microstructure response. Machining was performed on Ni-200 in the plane strain configuration inside the chamber of a scanning electron microscope. Mechanics of material flow i…
Impurity diffusion coefficients are entirely obtained from a low cost classical molecular statics technique (CMST). In particular, we show how CMST is appropriate in order to describe the impurity diffusion behavior mediated by a vacancy mechanism. In the context of the five-frequency model, CMST allows to calculate a…
Materials subjected to extreme conditions, such as very rapid heating, behave differently than materials under more ordinary conditions. In this program we examined the effect of rapid heating on solid-state chemical reactions in metallic materials. One primary goal was to develop experimental techniques capable of ob…
The work deals with the forming of the structure of testing complex for working out vibration strength of heavy objects due to the conditions and the level of dynamic correlation of its elements.
Influence of width of the filter on characteristics of intensity and kind of density of distribution of instant values and bending around narrow-band components of a spectrum of vibration of gas turbine engine is considered. Experimental data of width of discrete components of a spectrum of vibration of engines of ser…
The disk harmonic finite element was developed. FORTRAN code program was developed for modal analysis of rotating nonuniform heated disks from the gas turbine engines. Natural frequencies of disks were explored.
Techniques for modeling stable fatigue crack growth in highly stressed structural parts under simple and complex loading cycles have been developed which are based on the theory of local high-energy-type fracture mechanism acting at a crack front in the second stage of fatigue crack kinetics. The techniques have been…
