Title: Innovative Contributions of Mario Mariotti
Introduction
Mario Mariotti, an esteemed inventor located in Carcare, Italy, has made significant strides in the field of light-sensitive emulsions, holding three patents that showcase his inventive spirit and technical expertise. His work is particularly notable for its application in photographic materials, where he has developed novel formulations that enhance the performance and sensitivity of photographic emulsions.
Latest Patents
Among Mariotti's most recent contributions are his patents concerning silver bromoiodide core-shell grain emulsions. One of his inventions relates to a light-sensitive emulsion consisting of silver bromoiodide grains structured in a core-shell formation. The inner core predominantly comprises silver bromide or silver bromoiodide, with a specific silver iodide content ranging from 0 to 10 mole %. Surrounding the core are multiple shells made up primarily of silver bromide or silver bromoiodide. A unique feature of this invention is the inclusion of a pure silver iodide phase interposed between the shells, with greater than 5 mole % iodide content in at least one shell.
Another of his recent patents describes a core-shell silver bromoiodide emulsion where the inner core consists mainly of silver bromoiodide. Here, the silver iodide content varies between 30 to 50 mole % for the core, while the outer shell presents a lower silver iodide content of 1 to 10 mole %. This patent underscores the innovative ratio of X-ray diffraction peaks, highlighting the advanced nature of his work.
