Structural and Electromagnetic Signatures of Anatase and Rutile NTs and Sheets in Three Different Water Models under Different Temperature Conditions.

Experimental studies of TiO2 nanotubes have been conducted for nearly three decades and have revealed the remarkable advantages of this material. Research based on computer simulations is much rarer, with research using density functional theory (DFT) being the most significant in this field. It should be noted, however, that this approach has significant limitations when studying the macroscopic properties of nanostructures such as nanosheets and nanotubes. An alternative with great potential has emerged: classical molecular dynamics simulations (MD). MD Simulations offer the possibility to study macroscopic properties such as the density of phonon states (PDOS), power spectra, infrared spectrum, water absorption and others. From this point of view, the present study focuses on the distinction between the phases of anatase and rutile TiO2. The LAMMPS package is used to study both the structural properties by applying the radial distribution function (RDF) and the electromagnetic properties of these phases. Our efforts are focused on exploring the effect of temperature on the vibrational properties of TiO2 anatase nanotubes and an in-depth analysis of how the phononic softening phenomenon affects TiO2 nanostructures to improve the fundamental understanding in different dimensions and morphological configurations. A careful evaluation of the stability of TiO2 nanolamines and nanotubes at different temperatures is performed, as well as the adsorption of water on the nanosurface of TiO2, using three different water models.

Experimental Studies on TiO2 NT with Metal Dopants through Co-Precipitation, Sol-Gel, Hydrothermal Scheme and Corresponding Computational Molecular Evaluations.

In the last decade, TiO2 nanotubes have attracted the attention of the scientific community and industry due to their exceptional photocatalytic properties, opening a wide range of additional applications in the fields of renewable energy, sensors, supercapacitors, and the pharmaceutical industry. However, their use is limited because their band gap is tied to the visible light spectrum. Therefore, it is essential to dope them with metals to extend their physicochemical advantages. In this review, we provide a brief overview of the preparation of metal-doped TiO2 nanotubes. We address hydrothermal and alteration methods that have been used to study the effects of different metal dopants on the structural, morphological, and optoelectrical properties of anatase and rutile nanotubes. The progress of DFT studies on the metal doping of TiO2 nanoparticles is discussed. In addition, the traditional models and their confirmation of the results of the experiment with TiO2 nanotubes are reviewed, as well as the use of TNT in various applications and the future prospects for its development in other fields. We focus on the comprehensive analysis and practical significance of the development of TiO2 hybrid materials and the need for a better understanding of the structural-chemical properties of anatase TiO2 nanotubes with metal doping for ion storage devices such as batteries.

Análisis de la fuerza y movilidad de la cadera como factores de riesgo de lesión en fútbol femenino amateur: un estudio piloto / Analysis of hip strength and mobility as injury risk factors in amateur women’s soccer: a pilot study

Objetivos: Los objetivos del presente estudio consisten en aalizar la incidencia de lesiones no traumáticas de las extremidades inferiores en un equipo amateur femenino de fútbol y valorar su relación con la fuerza de la musculatura abductora y la movilidad en rotación externa de la cadera. Material y método: La presente investigación consiste en un estudio epidemiológico, observacional, analítico, longitudinal prospectivo. La muestra se seleccionó mediante un muestreo por conveniencia quedando compuesta por las 23 jugadoras que compusieron la plantilla del E.F. Mareo en la temporada 2013-2014, equipo ubicado en la Segunda División Nacional Española. El rango de edad de las participantes fue de los 14 a los 33 años (x=22,5; s=5,7). Las jugadoras fueron evaluadas en pretemporada y posteriormente se las siguió hasta el final del período competitivo para registrar las lesiones aparecidas. Resultados: Se apreciaron diferencias estadísticamente significativas entre la extremidad inferior dominante y la no dominante tanto en la fuerza de la musculatura abductora como en los rangos de movilidad en rotación externa de la cadera (p < 0,01). A lo largo de la temporada, el 52,2% de las participantes se vio afectado por alguna lesión no traumática en las extremidades inferiores. En cuanto a la tipología, el 53,8% fueron ligamentosas y afectaron principalmente al tobillo, con sólo una de ellas afectando a la rodilla (rotura de LCA), mientras que el 15,4% fueron lesiones tendinosas que afectaron a la rodilla y el 30,8% restante fueron lesiones tendinosas en la cadera. No se apreció relación de la fuerza de la musculatura abductora o de la movilidad en rotación externa de la cadera con la producción de lesiones. Conclusiones: Resultan necesarias más investigaciones para alcanzar resultados concluyentes

Objectives: The aims of the present study were to analize the incidence of overuse injuries of the lower limbs in an amateur women ́s soccer club throughout a competitive season and to assess its relationship with hip abductors strength and hip external rotation mobility. Material and methods: This research is an epidemiological, observational, analytical, prospective longitudinal study. The sample was selected by a non-random convenience sampling and it was composed of the 23 football players who made up the team of the E. F. Mareo in 2013-2014 season. Participant ages ranged between 14 and 33 years (x=22.5; s=5.7). The players were subjected to an evaluation of their hip abductors strength and hip external rotation mobility in preseason and, then, they were followed until the end of the competitive period recording the injuries that were appearing. Results: Statistically significant differences were observed between the dominant and non dominant limbs in hip abductors strength and hip external rotation mobility (p< 0.01). Along the season, 52.2% of the participants experienced some kind of overuse injury affecting the lower extremities. Regarding the type of injury, 53.8% were ligamentous injuries mainly affecting the ankle, only one of them involved the knee (ACL tear), 15.4% were tendinous injuries affecting the knee and the remaining 30.8% were tendinous injuries affecting the hip. No significant relationship was observed between overuse injury incidence and player’s hip abductors strength or hip external rotation mobility. Conclusions: More research is needed to achieve concluding evidence about the influence of hip abductor strength and hip external rotation mobility on overuse injuries of the lower extremities in women's soccer

Introducción: El control del nivel de práctica de actividad física que realizan los adolescentes, de sus factores determinantes y susceptibilidad al cambio resulta indispensable para intervenir sobre la epidemia de obesidad que afecta a la sociedad española. Sin embargo, el número de cuestionarios validados para valorar la actividad física en adolescentes españoles es escaso. Objetivos: Evaluar la validez del cuestionario 24h Previous Day Physical Activity Recall (PDPAR-24) cuando es aplicado a la población de adolescentes españoles. Método: Participaron en este estudio estudiantes de 14-15 años de dos centros de educación secundaria del norte de Galicia. Como criterio objetivo de la actividad física realizada se utilizó el registro proporcionado por el acelerómetro Actigraph GT3X. Se monitorizó a los sujetos durante un día por medio del acelerómetro y al día siguiente se administró el cuestionario de auto-informe. Resultados: Un total de 79 alumnos (15.16 ± 0.81 años, 39% mujeres) finalizaron el estudio. Se observan correlaciones positivas estadísticamente significativas de tamaño medio a grande en ambos sexos (r=0.50-0.98), para la actividad física ligera y moderada. Las correlaciones observadas son más elevadas a medida que aumenta la intensidad de la actividad física realizada. Conclusiones: El cuestionario de auto-informe PDPAR-24 puede ser considerado como una herramienta válida a la hora de valorar el nivel de actividad física en adolescentes españoles (AU)
