Sol-gel preparation of a di-ureasil electrolyte doped with lithium perchlorate
Silva, Maria Manuela; Nunes, Sílvia; Barbosa, P. C.; Evans, A.; Zea Bermudez, V. de; Smith, Michael John; Ostrovskii, DavidProva tipográfica (In Press) ; Solid polymer electrolytes (SPEs) synthesized by the sol-gel process and designated as ormolytes (organically modified electrolytes), have been prepared through the incorporation of lithium perchlorate, LiClO4 into the U(2000) organic-inorganic hybrid network. Electrolytes with lithium salt compositions of n (where n indicates the number of oxyethylene units per Li+ ion) between ...
Novel solid polymer electrolytes based on poly(trimethylene carbonate) and lith...
Silva, Maria Manuela; Barbosa, P. C.; Evans, A.; Smith, Michael JohnProva tipográfica (In Press) ; The results of the characterization of a polymer electrolyte system based on the poly(trimethylene carbonate) host matrix, with lithium hexafluoroantimonate as guest salt, are described in this study. Electrolytes with lithium salt compositions with values of n between 5 and 100 (where n represents the total number of monomeric cation-coordinating units -(O=COCH2CH2CH2O)- per lit...
Comparison between bulk micromachined and CMOS x-ray detectors
Rocha, J. G.; Schabmueller, C. G. J.; Ramos, N. F.; Lanceros-Méndez, S.; Evans, A. G. R.; Wolffenbuttel, R. F.; Correia, J. H.This paper compares two x-ray detectors fabricated using two different technologies: one is based on a bulk micromachined silicon photodetector and the other is based on a standard CMOS photodetector. The working principle of the two detectors is similar: a scintillating layer of CsI:Tl is placed above the photodetector, so the x-rays are first converted into visible light (560nm) which is then converted into a...
Comparison between bulk micromachined and CMOS detectors for X-ray measurements

X-ray detector based on a bulk micromachined photodiode combined with a scintil...
Rocha, J. G.; Schabmueller, C. G. J.; Ramos, N. F.; Lanceros-Méndez, S.; Costa, Manuel F. M.; Evans, A. G. R.; Wolffenbuttel, R. F.; Correia, J. H.This paper reports the design, fabrication, assembly and testing of a x-ray detector based on a bulk micromachined photodiode (BMMPD) with a cavity filled with a scintillating crystal. The x-ray photons that reach the detector are first converted to visible light by the scintillating crystal. The visible light is then detected by the BMMPD, producing an electric current with value proportional to the incident x...
