Publication number: 20240132363Abstract: A method for fabricating a Bismuth-doped silica-based optical composition. The method has the steps of: depositing SiO2 to obtain a silica material, soaking the silica material into an aqueous Bismuth solution, incorporating GeO2 into the silica material, and vitrifying the silica material at a temperature greater than 1500° C. to obtain the Bismuth-doped silica-based optical composition. In some embodiments, the fabricated Bismuth-doped silica-based optical composition has GeO2 of greater than 12 mol % (such as 19 mol %) and is suitable for transmitting therethrough optical signals of one or more of E and S bands.Type: ApplicationFiled: October 19, 2023Publication date: April 25, 2024Inventors: Victor Fuertes de la Llave, Lixian Wang, Younés Messaddeq, Sophie Larochelle

Patent number: 11365386Abstract: There is described a cellular behaviour monitoring device for monitoring changes in behaviour of cells contained in a sample. The device generally has a well plate with a sample receiving well recessed therein. A filter membrane extends across the well plate and hermetically covers the sample receiving well. The filter membrane has nutrient-permeable and cell-impermeable pores extending through the filter membrane. The device has an electrode layer extending across the filter membrane. The electrode layer has a substrate and behaviour monitoring electrodes spaced-apart from one another in a region of the substrate, with the region being aligned with the sample receiving well. The electrode layer has nutrient-permeable apertures distributed across the region, with at least some of pores are aligned with at least some of the apertures to allow fluid communication therebetween, and nutrient exchange between the sample receiving well and a surrounding environment.Type: GrantFiled: May 3, 2019Date of Patent: June 21, 2022Assignee: UNIVERSITÉ LAVALInventors: Benoit Gosselin, Younès Messaddeq, Jacques Corbeil, Eric Bharucha

Patent number: 9851326Abstract: An electrochemical ion sensor and a method for sensing a presence of at least one ion species in a solution are provided. The electrochemical sensor includes a solid-state electrolyte medium doped with an organometallic material, having an electrochemical affinity with the ion species, and a pair of electrodes electrically contacting the solid-state electrolyte. The electrochemical sensor also includes an electrical circuit configured to drive the pair of electrodes with an AC electrical excitation and to measure at least one parameter related to a complex electrical impedance of the doped solid-state electrolyte medium in response to the AC electrical excitation. The parameter may be an electrical resistance, an inductance or a combination of both, and represents the presence of the ion species in the solution when the solid-state electrolyte medium is exposed to the solution.Type: GrantFiled: November 22, 2013Date of Patent: December 26, 2017Assignee: UNIVERSITÉ LAVALInventors: Jean-François Viens, Charles-Olivier Normandeau, Younes Messaddeq
