Different Pt-based electrocatalysts supported on carbon nanofibers and carbon black (Vulcan XC-72R) have been prepared using a polymermediated synthesis. The electrocatalysts have been characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD) and cyclic voltammetry. The effect of carbon nanofibers…

This study explored the relationship between male and female dance partners. Participants were 171 Hungarian competitive dancers. The study focused on how the competitors view their own partnership (how they define this relationship), how important they consider it for success,…

The physical and physiological demands of high-level male soccer have been studied extensively, while few studies have investigated the demands placed on females during match-play, however, there is no information available about the heart rate and activity profile of young…

Despite increased numbers of female researchers, women still face more difficulties than their male counterparts when it comes to publishing their work and having it read and cited. In this editorial, the main recommendations are detailed in order to promote…

Technical teaching often requires the use of expensive laboratory materials which are frequently beyond the reach of many students. Students are also required to go to laboratories, which offer the appropriate facilities, according to a strict timetable. For these reasons,…

Doped tin dioxide electrodes have been prepared by a standard spray pyrolysis technique. The electrochemical behaviour of these electrodes has been investigated by cyclic voltammetry in sulphuric acid using the Fe2+/Fe3+ redox couple system as test reaction. Oxygen evolution has…

The authors have developed a simple method to compare the colour gamuts of
different industries (printing, textiles, plastics, etc.) based on representing the reproduced
colours in constant lightness L* and hue hab* planes. This method allows the analysis of those

The electrochemical oxidation of serine and alanine was performed at Pt(100) and Pt(110) electrodes and analysed by means of FTIR spectroscopy and cyclic voltammetry. The open circuit adsorption of both amino acids was also investigated. The oxidation of serine gives…

This paper begins with a description on the state of the art of robotics education in Spain. We then
present our virtual environment and remote laboratory, whose principal component is RoboLab, a
system that allows the student to interact with…

Here we provide the first assessment of the accuracy of lightweight satellite transmitters (80 g) under actual operating conditions and the performance of the Argos system in southern Europe. To estimate transmitter accuracy we used transmitters equipped with a Global…
