La sédimentation des suspensions aqueuses de particules minérales microniques, polydisperses et concentrées a été analysée à l’aide du Turbiscan MA 2000 fondé sur la diffusion multiple de la lumière, en vue d’établir la procédure qui permet de déceler la présence d’une morphologie fractale, puis de déduire les règles…
Spinwave dispersions of magnetically ordered materials have been calculated by various authors. The reader is referred to seminal publications by Holstein-Primakoff, Dyson, Keffer, Akhiezer, etc., on the subject matter. Spinwave excitations in magnetic materials as well as superconductivity materials involve the colle…

As the body's natural scaffolding is largely comprised of collagen, a significant amount of research is being conducted focused on how to engineer collagen scaffolds with properties identical to natively derived collagen.A major benefit of utilizing collagen as the source material for tissue engineering scaffolds is i…
by Ian Steward ZnO is a well studied semiconductor that possesses great potential for creating high quality photovoltaic devices.Because of its low exciton binding energy, large band gap, low dielectric constant, and low cost, much effort has been devoted to developing p-type ZnO (necessary for forming robust homojunc…
In the title complex, [PtBr(4)(C(10)H(8)N(2))], the Pt(IV) ion has a slightly distorted octa-hedral coordination defined by two N atoms of the chelating 2,2'-bipyridine ligand and four bromide ions. As a result of the different trans effects of the N and Br atoms, the Pt-Br bonds trans to the N atom are slightly short…
Molar enthalpies of crystallization of (2 S,5 R,6 R )-6-amino-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo[3.2.0]heptane-2-carboxylic acid in sodium sulfate and ammonium sulfate aqueous solutions were estimated based on the solubilities. A positive effect of temperature on solubility of 6-APA in both Na 2 SO 4 and (NH 4 ) 2…
In the title salt, [Ag(2)(CF(3)CO(2))(2)(C(10)H(8)N(2))](n), which may also be regarded as a coordination polymer if long Ag⋯O inter-actions are considered, each of the N atoms of the somewhat twisted 2,2'-bipyridine mol-ecule [N-C-C-N = -27.5 (4)°] binds to an Ag atom, and each of the carboxyl-ate ligands is tridenta…
We describe a feedback mechanism in the gas cascade amplification process used in magnetic immersion lens environmental scanning electron microcopy (ESEM). Feedback dominates gas gain under the conditions typically used for ultra-high-resolution ESEM and gives rise to novel dependencies of the imaging signal and noise…
Abstract Time of Flight Secondary Ion Mass Spectrometry (ToF‐SIMS) and XPS were utilized to assess the surface characteristics of the bonding wire generally used in electronic packaging applications. This paper outlines the proposed standard methodologies for the analysis of the high‐curvature surfaces of the fine bon…
The present study concerns the review and the analysis of malfunctions characteristic and the reasons of moving blade damage. Such malfunctions are breakage of moving blade in excessive temperature conditions, increasing vibration, little cyclic weariness from frequent heat exchange at start-up and shut-down, and eros…
The objective of the research is to investigate the effect of hard chrome electroplating on low carbon steel surface characteristic. This experimental research used low carbon steel as material that has been coated by hard chrome electroplating, chromium powder, and Pb alloy as cathode. The instrument for the research…
Aptamers, also known as chemical antibodies, are short single-stranded DNA, RNA or peptide molecules.These molecules can fold into complex three-dimensional structures and bind to target molecules with high affinity and specificity.The nucleic acid aptamers are selected from combinatorial libraries by an iterative in…
Effects of the milling time, annealing temperature and vial rotation speed were investigated on the formation of MoSi2–CrSi2 nanocomposite powder. X-ray diffraction was used to characterise the milled and annealed powders. The morphological and microstructural evolutions were studied by scanning electron microscopy an…
The title compound, sodium disilver arsenatotrimolybdate, Na(0.93 (1))Ag(2.07 (1))Mo(3)AsO(13), was prepared by a solid-state reaction. In the crystal structure, isolated AsO(4) tetra-hedra share corners with groups of three edge-sharing MoO(6) octa-hedra. This arrangement leads to the formation of anionic (1) (∞)[Mo(…
Crystals of the langasite family are of interest as they are piezoelectric in different devices. The properties of these classes of crystals can be modified within certain limits by isomorphous substitution. Single-crystal neutron diffraction studies were carried out for LGT (La(3)Ga(5.5)Ta(0.5)O(14)), LGST (La(3)Ga(5…
