1. Uso de procesos pirometalúrgicas para la obtención de renio
ABSTRACT Rhenium is a metal that has different obtainment methods. The most used comes from molybdenite roasting. Traditional pyrometallurgical methods like oxidizing roasting are applied, but there are also innovative pyrometallurgical methods as is roasting with carbothermic reduction. This paper presents the behavior of rhenium onto two different roasting

2. Thermodynamic Feasibility of Pure Hydrogen Production and Storage in Iron and Germanium Based Double Chemical Looping Process
Solid iron based low or medium temperature chemical loop is considered as a possible option of hydrogen storage and production. In the method, hydrogen is produced via iron oxidation with steam, and in the next phase iron oxide is reduced with hydrogen, synthesis gas or methane. In the reduction stage the reaction is terminated when the atmosphere still cont

3. Thin Tin and Tio2 Film Deposition in Glass Samples by Cathodic Cage
Thin nitride and titanium dioxide films were produced using an innovative technique called cathodic cage depositon. Uniformity, three-dimensionality and high rate deposition are some of the advantages of this technique. In this study we discuss the influences of temperature, treatment time and gaseous atmosphere on the characteristics of the deposited films.

4. Respiratory quotient: innovative method for monitoring ‘Royal Gala’ apple storage in a dynamic controlled atmosphere
Apples (Malus domestica, Borkh.) which are not stored at low temperature or in a properly controlled atmosphere (CA) may have a high metabolic rate during the postharvest stage resulting in losses in quality. The aim of this study was to evaluate the quality of ‘Royal Gala’ apple fruit stored in accordance with a new method of dynamic controlled atmosphe

5. Innovative low temperature plasma approach for deposition of alumina films
Alumina films were deposited from a new plasma method using aluminum acetylacetonate (AAA) powder as precursor. The AAA was sputtered in argon and oxygen plasma mixtures. It was investigated the effect of the oxygen proportion (O2%) on the properties of the coatings. Deposition rate was derived from the layer height measured by profilometry. The elemental co

6. Construcción social del conocimiento matemático durante la obtención de genes en una práctica toxicológica
This research report focuses on the study of the social practices in the construction of mathematical knowledge. Unlike the traditional focus on the study of explicit mathematical concepts, this study focused on the presence of mathematical concepts in the scientific atmosphere of a toxicologist, where they are used implicitly. We employ a construct that we

9. PRODUÇÃO DE PIGMENTOS INORGÂNICOS A BASE DE ZrSiO4 COM INCORPORAÇÃO DE PASTA ELETROLÍTICA DE PILHAS / PREPARATION OF INORGANIC PIGMENTS BASED ON THE ZrSiO4 OXIDE FROM A MIXTURE OF AN ELECTROLYTIC-PASTE WASTE OF ALKALINE BATTERIES AND ZrSiO4
Throughout the times, new pigment systems have been gradually developed. In the nowadays, the development of ceramic pigments represents a part of the Materials Science, where there is a lack of concepts, roles and strategies, which in goal allows the developing of new rotes of preparing or pigments, in both scientific and technological areas. This work deal
