Abstract:
Composite, nanoporous, proton membrane, comprising a polymer matrix compatible with proton ambient with ceramic particles of micrometric and submicrometric dimension, and having a proton-conducting gelified solution immobilized therein is disclosed. In said membrane, said polymer is preferably a PVdF-CTFE copolymer and said ceramic consists of SiO 2 particles. The membrane according to the invention provides high proton conductivity, low methanol dispersion, satisfactory stability and good behaviour of direct methanol fuel cells, using said system as separator at ambient temperature and especially at intermediate temperatures. A further advantage of this system is low cost, which is convenient in the fabrication of direct methanol fuel cells.
Abstract:
An apparatus (1) for automatic deposition comprising a deposition chamber (2); an airbrush (8), part of which (9) is lodged inside the deposition chamber (2); a supporting structure (3) for a substrate (4) lodged inside the deposition chamber (2); a quartz resonator (6) lodged inside the deposition chamber (2) and placed inside the airbrush (8) spraying zone; reading devices (12, 13) able to read the quartz resonator (6) frequency; and a master control unit (14) connected both to the reading devices (12, 13) and to the airbrush (8), and able to receive settings about the amount of material to be deposited on the substrate (4). The master control unit is able to do progressively: - receive the frequency values of the quartz resonator from the reading devices (12, 13), - compare these values with a sequence of values related to the resonator (6) frequency corresponding to a specific amount of material deposited on the substrate (4), and - control the airbrush (8) as consequence of the comparison performed and the amount of substance chosen to be deposited on the substrate (4).

Abstract:
The invention relates to the use of β- emitting radiolabeled tracers for administration to a patient prior to radio-guided surgery, and to the corresponding probes designed to intraoperatively detect β- decays from cancerous tissues so as to locate even small cancerous remnants still present after resection of the main cancerous lesions. The β- emitting radiolabeled tracer for use according to the invention is labeled with a radioisotope undergoing exclusively β- decays or a radioisotope undergoing β- decays and having no more than 10-11 % of γ rays decays, ptrgrtsbly no more than 5% of γ rays decays. The corresponding probe for use in combination with the β- emitting tracer proposed has an extension direction along a longitudinal axis and comprises one or more blocks of scintillating material, each one having a main extension parallel to the longitudinal axis and transversal dimensions smaller than 3 mm, each of said one or more blocks being partially shielded by a material that is inactive with respect to β- radiation.
