Nowadays, we are heading towards global decarbonisation, with each sector involved contributing partial solutions to the problem, without realising that an overall vision is necessary. Photovoltaics emerged as a technology that requires a lot of surface area, which is why it has been integrated into buildings and other human infrastructures (BPVI)....

The analysis of energy consumption in reverse osmosis desalination plants is the most important and relevant factor to study, because this parameter indicates the level of efficiency and competitiveness of the plant. The direct consequence of the high specific energy consumption (SEC) of a desalination plant in the production of water is one of the...

The study aims to characterize two alloys in order to evaluate if they can be used for medical applications, these alloys have the following compositions: A1 (93.2% Ti, 4% Fe, 2% Al, 0.8% V) and A2 (96.5% Ti, 3% Mn, 0.6% Al, 0.2% V). Information on the behavior of the samples was obtained, studying how the composition of the materials and the prese...

Over the years, we have seen how, thanks to experimentation on animal models, the foundations have been laid in the field of implantology. In most cases, studies related to the bone scale are carried out on the species that are most similar in their movements and behavior to humans. The femur has been selected as the reference bone for our test, se...

Due to the compatibility problems of biomaterials currently used in biomedicine, the effect of Silicon addition to the innovative TiMoZr alloy has been investigated. The mechanical properties of these two alloys and their corrosion resistance in simulated body fluid were analyzed in order to recommend them for the manufacture of medical instruments...

In this study, the ability of two titanium alloys to resist corrosion has been analyzed. This was accomplished by analyzing how the corrosion potential evolves with time as well as observing the Bode and Nyquist diagrams obtained with electrochemical impedance spectroscopy. The proportions of each alloy were A1 (94.4 % Ti, 4 % Mn, 0.6 % Al, 1 % Fe)...

The development of Ti-based alloys with improved properties for medical applications is a challenge nowadays in the field of materials engineering. In this study, the color of oxide layers developed by anodic oxidation in H2SO4 solution on Ti–Ta alloys was studied and the alteration in microhardness was evaluated. The alloys were manufactured by le...

Ti and its alloys have the most satisfactory properties for biomedical applications due to their specific strength, high corrosion resistance, and high biocompatibility. Ti-6Al-7Nb has been approved for clinical use, proving to be a viable replacement for the Ti-6Al-4V alloy that has been used for many decades in medical applications. In our study,...

Titanium alloys are used in medical devices due to their mechanical properties, but also for their corrosion resistance. The natural passivation of titanium-based biomaterials, on the surface of which a dense and coherent film of nanometric thickness is formed, composed mainly of TiO2, determines an apparent bioactivity of them. In this paper, the...

Depending on the properties required for the medical instruments, compared with the classical materials, the high-entropy alloys (HEAs) are a versatile option. Electrochemical Impedance Spectroscopy (EIS) measurements have been performed on AlxCoCrFeNi-type high-entropy alloys with various concentrations of Al content (x = 0.6, 0.8, and 1.0) in ord...

Hourly concentration averages of tropospheric ozone were measured, during the period from January 2007 to December 2007, in a street with a lot of traffic in Las Palmas de Gran Canaria. The values obtained, calculated by maximum daily concentration of every eight hours average, were below the limit value set by the European Union Directive 2008/50...
