TiO2 based Inorganic-Organic Hybrid Photocatalysts for Highly Selective Alcohol Partial Oxidation
2015
An integrated approach to develop a composite hybrid material made of titanium dioxide functionalized with an organic conjugated phenol (DIOL) and silver NPs suitable for the selective oxidation of water soluble aromatic alcohols to aldehydes in water under UV irradiation and very mild conditions was used. The 86% selectivity observed for the Rutile/DIOL/Ag composite is, to the best of our knowledge, the highest thus far reported for partial oxidation of aromatic alcohols to aldehydes in water suspensions of titanium dioxide. The method is general as it relies on the concomitant easier adsorption of the aromatic alcohol and more facile release of the aldehyde, coupled to fast interfacial el…

Novel dosimetric gels for three-dimensional dose mapping in radiotherapy
2016
One of the most recent and promising developments for radiotherapy (RT) dosimetry was the introduction of 3D radiation- sensitive gels. The gels are tissue equivalent, so they also serve as a phantom, and their response is largely independent of rad iation quality and dose rate. Some gels are infused with ferrous sulfate and rely on the radiation-induced oxidation of ferrous ions to ferric ions (Fricke-gels) . These gels suffer from spontaneous-oxidation and diffusion of ferric ions after irradiation; the latter is significantly reduced by chelating agents such as xylenol orange (XO) (Fricke-XO gels) [2]. Other formulations consist of dispersed monomers, and rely on radiation-induced cross-…
PLA/PLLA scaffold for vascular tissue engineering applications
2011
A critical obstacle encountered by tissue engineering is the inability to maintain large masses of living cells upon transfer from the in vitro culture conditions to host in vivo. Capillaries, and the vascular system, are required to supply essential nutrients, including oxygen, remove waste products and provide a biochemical communication “highway”. Another task in this research field is the possibility to tune the biodegradability of the scaffold. After implantation, the scaffold must be gradually populated by cells and replaced by extra cellular matrix; with this respect, it is crucial that this replacement takes place with appropriate dynamics and a well-defined timescale. A premature d…
