Title: Jong-Shinn Wey: Innovator in Silver Halide Emulsions
Introduction
Jong-Shinn Wey is a notable inventor based in Penfield, NY (US). He has made significant contributions to the field of photography through his innovative processes related to silver halide emulsions. With a total of 5 patents to his name, Wey's work has advanced the understanding and application of silver halide technology.
Latest Patents
Wey's latest patents include a process for independently monitoring the presence of and controlling silver halide emulsions. This process involves adding silver ions to a dispersing medium containing halide ions within a reaction vessel to initiate the growth of silver halide grains. The method includes monitoring the temperature of the dispersing medium to establish the equilibrium solubility product constant of silver and halide ions. Concurrently, the halide ion activity is monitored using a reference electrode and an indicator electrode. The process allows for the adjustment of dissolved halide ions to maintain a stoichiometric excess, ensuring optimal conditions for silver halide grain growth. Another significant patent involves producing photographically useful radiation-sensitive silver halide emulsions with controlled grain size distribution. This is achieved by modifying a double jet precipitation method to introduce stable silver halide grains during the process, allowing for precise control over the maximum and minimum grain diameters.
