The elementary characterization of anthill clay for composite materials

Anthill clay is a distinct soil/clay genre among common soil types because of the extraordinary stockpiling method. The small particles are carried in and erected an anthill by a small creature that it is called as termite. In generally, clay is a conspicuous raw material for industrial applications greatly and the assay of expediencies of anthill clay for advanced material applications were the prospects of the existing research. Carefully collected anthill clay samples were characterized under the physically and chemically using standard procedures and instruments. The mechanical characteristics of prepared bricks from anthill clays under 8000C were investigated. As the major outcomes of the existing investigation of raw clays, there were looked to 5.56 of PH value, 15% of natural moisture content, gap graded and symmetrically distributed arrangement of grains, 60% finer particle percentage (<0.075mm) according to the weight, composition of Fe, Ti, Ba and K based compounds including Fe minerals with large sorption capacity for other metals. In addition that 25% of water absorption, 2.62 of bulk specific gravity, 65% of apparent porosity, 21 Mpa compressive strength and 0.4 Mpa splitting tensile strength were observed with respect to the bricks which were prepared from the anthill clay. Based on the behaviors of such anthill clay it should be an influential material in the advanced material manufacturing in the industrial purposes such as the water treatments, rigid materials, catalysts and refractors.

Caracterización elemental del alquitrán del cigarro por medio de espectroscopia de fluorescencia de rayos-X dispersiva en energía Elementary characterization of tar of cigar by means of energy dispersive X-ray fluorescence spectroscopy Paolo G. Tataje, Daniel A. Muñoz, Jorge A. Bravo Facultad de Ciencias Físicas, Universidad Nacional Mayor de San Marcos, Av. Venezuela S/N, Lima, Perú. DOI: https://doi.org/10.33017/RevECIPeru2016.0001/ Resumen Se analizó una muestra de alquitrán por medio de la técnica de fluorescencia de rayos-X dispersiva en energía (FRXDE) con la finalidad de obtener en forma cuantitativa la composición elemental inorgánica que este presenta. La sustancia tóxica se extrajo de una marca de cigarro genérica mediante un experimento que simula, de forma muy eficiente, los pulmones de un fumador. Los resultados del presente trabajo enmarcan una diferencia entre el tabaco y lo que se obtiene de la combustión de este ingresando a los pulmones Descriptores: alquitrán, fluorescencia de rayos-x dispersiva en energía, composición elemental. Abstract A Tar sample was analyzed by energy dispersive X-ray fluorescence spectroscopy (EDXRF) in order to obtain quantitatively its elemental inorganic composition the elemental composition. The toxic substance was extracted from a generic brand of cigar through an experiment that simulates, very efficiently, the lungs of a smoker. The results of this work show a difference between tobacco and what is obtained from the combustion entering the lungs. Keywords: tar, energy dispersive X-ray fluorescence spectroscopy, elementary composition.

A characterization of the quaternion group

The goal of this note is to give an elementary characterization of the well-known quaternion group Q8 by using its subgroup lattice.
