The most suitable techiniques and methods to identify high alumina cement and based portland cement in concretes
Instrumental techniques are indicated and the most adequated methodologies for determining the nature of the binder in concretes are explained. These methods are: a) Determination of the Silicic Moduli through chemical analysis of the sample. This test reveáis very different valúes between cement portland based concre…

Influence of metal–metal interaction on magnetic and redox properties in different series of heterodinuclear copper(II), nickel(II), and zinc(II) complexes
Different series of heterodinuclear complexes, viz.,|CuNiL](ClO 4 ) 2 •nH 2 O,[CuZnL](ClO 4 ) 2 •nH 2 O,[NiCuL](ClO 4 ) 2 •nH 2 O, and [NiZnL](ClO 4 ) 2 •nH 2 O complexes where L is a dinucleating Schiff base ligand derived from the condensation of 1 mole of 2-hydroxy-5-methylbenzene-1,3-dicarbaldehyde, 1 mole of 1,3-…
Electrochemical Characteristics of Poly(trans‐1,2‐di(2‐thienyl)ethylene) and Its Battery Application
The electrochemical characteristics of poly(trans‐1,2‐di(2‐thienyl)ethylene) and its battery characteristics have been studied. Poly(trans‐1,2‐di(thienyl)ethylene)s prepared from both trans ‐1,2‐di(thienyl)ethylene and cis ‐1,2‐di(thienyl)ethylene show reversible doping‐undoping behavior and excellent charge‐discharge…
Phase and density changes during the ''conversión'' reaction of high alumina cement
The basis of the conversion reaction, in which high alumina cements develop hydrogarnet subsequent to their set, is weel-established and its mineralogical features accord with phase equilibrium relations in the CaO-Al2O3-H2O system. What is less well understood is the role of silica in the conversion. Silica may subst…
Tourmaline group crystals reaction with water
The pyroelectricity in tourmaline crystals has proved to be the secondary pyroelectric effect due to the thermal expansion and the piezoelectricity. On the c-face of a tourmaline powder of radius a [μm], there exists the electric field of 107 [V/m] which decreases following (a/r)3 at distance r and is faint at teen [μ…
Morphological changes in isotactic polypropylene as a function of cooling rate
A new method for monitoring rather than controling thermal history has been applied recently to analyze the crystallization kinetics at high cooling rate of a highly pure isotactic polypropylene, proving that the cooling history relevant to the structure of quenched samples is in the neighborhood of 90°C. A continuous…
Magnetic properties of MnBi prepared by rapid solidification
The magnetic properties of the low-temperature phase of MnBi, prepared by rapid solidification, have been measured in a pulsed field over the temperature range 80--625 K. The anisotropy field, obtained by the singular-point-detection technique, is found to increase with temperature and has a maximum value of 9 T at 53…
Explosive Hydrogen Burning
Following a major shortage of 99Mo in the 2009–2010 period, concern grew that the aging reactor production facilities needed to be replaced. Most producers were using highly enriched 235U (HEU) as the target material. The Organisation for Economic Co-...Read More
Theoretical study of titanium surfaces and defects with a new many-body potential
It is shown that any force model using short-range pair-functional interactions can only have three independent h.c.p. elastic constants. Empirical data show that these elastic properties are nearly realized in a number of materials. A new parametrization of a Finnis-Sinclair-type many-body potential for titanium is p…
