Photodegradation of organic compounds in water solutions by means of economically advantageous and environment-friendly processes is a topic of growing interest. In recent years a great attention has been devoted to TiO2-based photocatalysts for the oxidative degradation of various organic pollutants. In this context, we have prepared new photo-catalytic polycrystalline TiO2 systems impregnated with sensitizers, i.e., copper, iron or manganese porphyrins, and investigated their photoactivity for 4-nitrophenol oxidation compared with that of bare TiO2. A significant improvement of the photoreactivity was observed in the case of TiO2 impregnated with copper porphyrin, while only a slight bene…

Plasma electrolytic oxidation (PEO) was applied using a pulsed unipolar waveform to produce Al2O3-TiO2 composite coatings from sol electrolytic solutions containing colloidal TiO2 nanoparticles. The sol solutions were produced by dissolving 1, 3, and 5 g/L of potassium titanyl oxalate (PTO) in a silicate solution. Scanning electron microscopy, energy dispersive spectrometry, X-ray diffraction, and Raman spectroscopy were applied to characterizing the coatings. Corrosion behavior of the coatings was investigated using polarization and impedance techniques. The results indicated that TiO2 enters the coating through all types of micro-discharging and is doped into the alumina phase. The higher…

jogabel@alumni.uv.es La monitorización de la presión tisular de oxigeno (PtiO2) permite el conocimiento de las repercusiones de las lesiones tisulares y el diagnóstico de lesiones secundarias en el paciente con traumatismo craneoencefálico grave (TCEG). Este método de monitorización detecta cambios fisiopatológicos que conllevan las lesiones neurotraumáticas. El objetivo de nuestro artículo es describir y analizar este tipo de monitorización, así como los cuidados de enfermería con relación a los casos que hemos atendido en nuestra unidad y según nuestra experiencia. Se ha confeccionado una hoja de “registro de enfermería” que contiene los datos del paciente, diagnóstico, tipo de catéter, c…
