Patent number: 7543565Abstract: Optical system for detecting the concentration of combustion products operating in situ and at high temperature based on measurement of the optical absorption of a gaseous mixture of combustion products through a photodetecting sensor based on gallium nitride (GaN), aluminium nitride (AlN), indium nitride (InN) and corresponding alloys. The operating temperature of the sensor preferably lies between 500° C. and 700° C., but the resistance of the active material permits use at even higher temperatures. This system can be used to measure the concentration of chemical species present in combustion products directly at their outlet, where the high operating temperature makes it possible to avoid fouling of the sensor caused by carbonaceous and non-carbonaceous deposits. The rate of response of the system is less than or equal to 1 millisecond and makes it possible to adjust the parameters of an associated combustion process control system in real time.Type: GrantFiled: December 22, 2004Date of Patent: June 9, 2009Assignee: Consiglio Nazionale Delle Ricerche - INFMInventors: Domenico La Forgia, Arturo Antonio De Risi, Massimo De Vittorio, Roberto Cingolani, Adriana Passaseo, Mauro Lomascolo

Publication number: 20050074697Abstract: Masters for imprint processes are produced by providing a resist layer, and patterning the resist layer after a respective mold pattern to produce a patterned resist layer adapted to be directly used as a master for imprint lithography. Preferably the resist is spin cast on a substrate and is comprised of a photoresist, such as negative-tone, electron-beam sensitive resist having a glass transition temperature above 200° C. and adapted to be mechanically stable to pressures up to 104 psi. Preferably, the resist is a polymer resist, such as an epoxy resist e.g. SU8 and SU8-2000. Patterning the resist layer includes the steps of structuring the resist layer, soft-baking the structured resist layer in order to selectively cross-link the structured portion of the structured resist layer and developing the structured resist layer in order to receive a patterned resist layer. The patterned resist layer is preferably cured e.g.Type: ApplicationFiled: September 21, 2004Publication date: April 7, 2005Inventors: Massimo De Vittorio, Sergio Bernardi, Dario Pisignano, Maria Todaro, Roberto Cingolani, Giuseppe Gigli
