    ABSTRACT: Nano-engineered membranes obtained by electro-hydrodynamic technologies have been proposed as a good candidate for active filtration. The present work reports some results on the development, production and characterization of three different nanostructured membranes based on: electrospun TiO2 inorganic nanofibers, nanocomposite structures of polymer nanofibers with TiO2 embedded nanoparticles and multilayered structures of polymer nanofibers and electrosprayed TiO2 nanoparticles. Their catalytic activity on volatile organic compounds (VOCs) decomposition has been explored in a photo-reactor properly design for this purpose and a comparison among their performance will be extensively discussed. Multilayered membranes showed a complete degradation of methanol in gas phase and the photo-catalytic activity has been found to be affected from the catalyst content and morphology, by means that there is a critical concentration of catalyst over which its increase results on worse photo-oxidation performance. Inorganic TiO2 based membranes revealed the same activity as the nanocomposite membranes, in terms of methanol reacted per gram of catalyst, but their poor mechanical properties makes them not suitable for a potential scale up.

    ABSTRACT: Electrically conductive polypropylene nanocomposites containing multi-walled carbon nanotubes were produced by melt blending by dilution of a concentrate masterbatch containing 10 wt.% of filler. In order to promote polymer infiltration within primary agglomerates a ultra-low melt viscosity polypropylene grade has been used for masterbatch production. Moreover, three polypropylenes with different melt viscosities have been used for successive dilutions. Filler dispersion has been assessed by both indirect macroscale analyses and direct morphological investigations. Characterization showed percolation thresholds occurring for very low filler contents. During dilution, lower polymer viscosities lead to more effective residue agglomerates dispersion, hence better electrical properties.

    ABSTRACT: Chronic dialysis treatment is characterized by a series of complex interdependent objective problems, such as the dialysis experience, the individual way to assess it, and some "protective" factors such as social and family support. Progresses in dialysis research show that dialysis patients have important alternatives to passively accept their condition: thanks to adequate psychological and relational aid, they can reach rather advanced adaptation levels, which allow them to modify both their behaviour and way of life, to keep a satisfactory compliance, and to improve their quality of life (QoL). In this adaptation process, both family and social support play an important role, although controversy still exists on it. The results of our study confirm the complexity of this role and show that either haemodialysis or peritoneal dialysis patients' adaptation process and QoL may be directly related to the extent of family member's ("caregiver") support. It is of particular interest the fact that patients, especially those undergoing haemodialysis, provided with a caregiver's assistance but who choose to "act by themselves", do have better adaptation levels and QoL than those who rely only on their caregiver. This fact reassesses the widely accepted point of view that continuous caregiver's support is always a positive and necessary factor in order to improve both the adaptation and the QoL of dialysis patients.

    ABSTRACT: When elderly patients with end-stage renal disease start dialysis their quality of life, and particularly the emotional aspects of it, are very similar to those of age-matched controls. However, as the treatment becomes chronic the quality of life will decline not only with regard to the physical aspects (due to comorbidities) but also the emotional aspects. Dialysis-related stress episodes and the peculiar interrelationships in the dialysis facility setting may cause psychological discomfort which on the one hand reduces the patient's quality of life and on the other may unfavorably impact on the family and the health-care personnel. An integrated psychological approach involving the patient from the beginning of dialysis throughout the treatment process as well as the healthcare personnel and the family can reduce the patient's psychological discomfort, thereby improving quality of life.

    ABSTRACT: Quality of life of the elderly patient on dialysis When elderly patients with end-stage renal disease start dialysis their quality of life, and particularly the emotional aspects of it, are very similar to those of age-matched controls. However, as the treatment becomes chronic the quality of life will decline not only with regard to the physical aspects (due to comor- bidities) but also the emotional aspects. Dialysis-related stress episodes and the peculiar interrelationships in the dialysis facility setting may cause psychologi- cal discomfort which on the one hand reduces the patient's quality of life and on the other may unfavorably impact on the family and the health-care per- sonnel. An integrated psychological approach involving the patient from the beginning of dialysis throughout the treatment process as well as the health- care personnel and the family can reduce the patient's psychological discom- fort, thereby improving quality of life.
