title: Effect of thermal treatment on points defects of Al-N codoped ZnO films

description: ABSTRACT The effect of annealing temperature on the structural properties of Al-N codoped ZnO films were studied by X-ray diffraction, photoluminescence and Raman spectroscopy. ZnO films were deposited by sputtering technique on silicon substrates at 20 ºC, Al-concentration was kept constant and N-flow was changed to 6, 12 and 15 sccm. A thermal treatment was performed by annealing the sample during 30 minutes at 300, 400, 500, 600 and 700 °C. Before annealing, Raman spectra shows two vibration modes located at 275 and 580 cm-1 associated to the nitrogen incorporation and the presence of point defects. Both Raman intensities of modes I275 and I580 decreases when the nitrogen flow increases from 6 to 12 and 15 sccm, which is originated by a decreasing interstitial defects density. The improving of the crystal quality was confirmed by x-ray diffraction and room temperature photoluminescence measurements. After annealing, in the Raman spectra it was observed that I275 increases as the temperature increase, reaches a maximum intensity between 500 and 600 °C, and decreases for higher temperatures. X-ray diffraction measurements show that after annealing the compressive stress decrease progressively as the annealing temperature increase. This study suggests that 275 Raman mode could be used to estimate the optimal thermal treatment in order to achieve p-doping ZnO.

title: Study of composition of gaseous phase by FTIR. MoO3 chlorination in presence of sucrose carbon

description: ABSTRACT Chlorination and carbochlorination studies available in the literature were conducted using gravimetric and thermogravimetric techniques. These studies were focused on the overall reaction through analysis of the condensed reaction products, thermodynamic calculations and mass change generated during the reaction. The composition of the gaseous phase in a carbochlorination process is complex; CO, CO2, and COCl2 gases can be formed as well as metal chlorides and/or oxychlorides. In this study, the carbochlorination reaction of MoO3 was studied by IR spectroscopy. This technique allows online detection of gases generated during the reaction. The results obtained by FTIR and other complementary techniques indicated that MoO3 carbochlorination with sucrose carbon proceeds not only with formation of CO2, also CO and HClO were detected. Results proved the formation of a reaction intermediate between Cl2 and carbon surface.

title: Analysis of corrosion of joints brazing copper matrix composites

description: ABSTRACT This work presents an electrochemical corrosion study in synthetic seawater of the dissimilar joint of TiC/Cu composite by brazing technique. Composites were machined by liquid infiltration without external pressure. This composite were joined with copper using a filler material constituted by an alloy of silver - copper and titanium powder. The composite joined shown a good adhesion forming a dissimilar assembled and coherent. In order to carry out the corrosion studies, two different techniques were used, potentiodynamic polarization curves (PCs) and electrochemical noise (EN). In addition, the corrosion potential measures as a function of the time were carried out to get the stabilization time of the anodic and cathodic reactions in the corrosion process. Electrochemical measurements were made at different exposure times with a total exposure time of 24 hours. A typical three-electrode electrochemical cell was used; where the working electrode (WE) was a sample of composite joined, the reference electrode was the saturated calomel electrode (SCE) and a sintered graphite rod was used as auxiliary electrode. The electrochemical results shown that the susceptibility to localized corrosion of the composite joined sample was higher than the based metal (copper). The corrosion mechanism of the composite joined sample is a differential aeration cell, where it can produce pitting and crevice corrosion form. The results shown a good correlation between the superficial analysis and the results obtained by the EN and CPs.

title: Development and Validation of an Instrument to Measure the Effect in respect to Error Commission in Mathematics

description: Abstract Mistakes may have a negative connotation and can cause negative affects in students toward mathematics. The objective of this research is to develop and validate an instrument which measures the affect of making mistakes in mathematics, and the affect towards mathematics due to errors. The instrument items are based on the relation between the error commission and the three affectivity components: emotions, beliefs, and attitudes. It was administrated to 319 freshmen in the Business School at a private university in Guadalajara, Mexico. The instrument showed strong reliability with an alpha Cronbach of 0,9. Factor analysis confirmed its validity with five constructs related to errors, that explain 52,73% of the total variance: 1) negative emotions and affects on making mistakes, 2) favorable conduct towards the use of errors as a learning tool, 3) mistaken conceptions in regards to usefulness of errors, 4) negative beliefs and emotions towards mathematics due to making mistakes, and 5) the belief that one can learn mathematics from errors. To be able to measure the affectivity students have developed towards errors in mathematics and towards mathematics due to making mistakes as well as their conceptions about errors, may offer a clearer view about of the error culture they have experienced during their school time. Due to this experience, beliefs and attitudes were formed and their behavior may tend to be favorable or not favorable towards their mathematics learning.

title: Evolution of magnetic response as a function of annealing temperature in Fe-based alloys

description: ABSTRACT The magnetic response, coercive force and magnetic induction, in Fe-10at.% Si, Fe-6at.% Al-9at.% Si and Fe-4at.% Al-8at.% Ge alloys as a function of the annealing temperature was determined and correlated to the microstructural state. The microstructural characterization was made through differential thermal analysis, mechanical spectroscopy and neutron thermodiffraction studies. It has been determined that the increase in the order degree and the decrease in the mobility of structural defects lead to a deterioration of the magnetic quality of the alloys above detailed.

title: Lipoprotein Profile Modifications during Gestation: A Current Approach to Cardiovascular risk surrogate markers and Maternal-fetal Unit Complications

description: Abstract Several changes occur in lipid metabolism during gestation due to hormonal and metabolic changes, which are essential to satisfy the nutritional demands of the maternal-fetal unit development. The gestation shows two distinct periods that begin with fat accumulation, mainly in maternal adipose tissue, and the late phase, characterized by accelerated catabolism, with the increase of fatty acids in the circulation that causes hyperlipidemia, especially the one characterized as hypertriglyceridemia. Maternal hyperlipidemia may be associated with the development of maternal-fetal complications (preterm birth, preeclampsia, vascular complications) and the development of long-term cardiovascular disease. The cardiovascular risk may not only be related to lipoproteins cholesterol content, but also to the number and functionality of circulating lipoprotein particles. This review reports themajor changes that occur in lipoprotein metabolismduring pregnancy and that are associated with the development of dyslipidemias, lipoprotein atherogenic phenotype, and maternal-fetal unit complications.

title: Magnetic Barkhausen noise for the study of magnetic anisotropy in stainless steels

description: ABSTRACT The magnetic Barkhausen noise (MBN) is a phenomenon that occurs in ferromagnetic materials when they are exposed to slowly varying magnetic fields, generating discrete jumps in their magnetization. These jumps are produced by the movement of the magnetic domain walls. They can be detected by a small coil allocated on the sample surface. The movement of the domain wall is regulated by the microstructure of the material (precipitates, grain size, residual stresses, etc.). Through this indirect way it is possible to characterize the material. In this work MBN measurements to study magnetic anisotropy induced by rolling processes and uniaxial strain tests are shown for ferritic stainless steels AISI: 409, 430 and 441A. The measurements were made at different strain percentages. The objective was to follow the changes in the MBN signals. The metallographic and hardness studies are presented. The results show a clear trend related with the direction of the principal stresses.

title: Young´s modulus measurements in metals using impulse excitation technique

description: ABSTRACT The impulse excitation, as non-destructive technique, allows to determine the elastic constants of materials by means of measurement of natural frequency of vibration of bars in different modes, excited by an impact in a point. In this work, the Young’s modulus of copper, aluminum and copper-based alloys samples was determined. The measurements were performed using different vibration modes: flexural in supported bars, and longitudinal. As a first step, the Young´s modulus of a sample was determined using different modes, finding consistency in results. On the other hand, the variation of the Young´s modulus was determined as a function of the temperature and microstructural parameters such as grain size. The capabilities and disadvantages of using the impulse excitation technique as a low-cost alternative in the field of research in metals and alloys are analyzed.

title: Determination of intercritical austenization parameters for development of multiphase steel using dilatometric analysis

description: ABSTRACT The Multiphase steels are materials with exceptional mechanical properties including high strength, excellent ductility and hardening coefficient and good conformability. These properties are related with the microstructure, which can be a combination of ferrite and martensite (Dual phase steels) or more complex microstructures with ferrite, bainite, martensite and retained austenite as in TRIP steels. One of the most important stages on the fabrication of multiphase steels is the intercritical austenization step which is performed between the A1 and A3 temperatures. This step determines the amount and chemistry (especially carbon) of the high temperature austenite. Aiming to study the intercritical austenization step, steels with variations in carbon (0.2-0.5wt%) and silicon (1.4-2.0wt%) were manufactured and dilatometric studies were conducted. The results allowed to stablish the intercritical austenization temperature (IAT) according with the needed amount of high temperature austenite. Also, the variation in chemistry of the high temperature austenite was studied as a function of the intercritical austenization temperature. (IAT) The results were analyzed according with the possibilities of the step after austenization, i.e., quenching or austempering and its impact on the microstructure and properties of the heat treated alloys.
