Title: Sherrill A Puckett: Innovator in Photographic Emulsions

Introduction

Sherrill A Puckett is a notable inventor based in Rochester, NY (US). He has made significant contributions to the field of photographic emulsions, holding a total of 5 patents. His work focuses on enhancing the performance and efficiency of silver halide emulsions.

Latest Patents

Puckett's latest patents include innovative technologies such as "Elevated iodide surface laminae tabular grain emulsions." This patent describes a tabular grain emulsion that combines increased speed, reduced low intensity reciprocity failure, and low levels of pressure sensitivity. The tabular grains contain greater than 70 mole percent bromide, with laminae located adjacent to the {111} major faces, each having a thickness of less than 35 nanometers. These laminae contain at least 1 mole percent higher iodide than the host portion of the tabular grains on which they are deposited. Additionally, the tabular grains include an iridium dopant capable of reducing low intensity failure in one interior grain portion and a Group 8 speed enhancing dopant present in a concentration of 20 to 300 molar parts per million in another interior grain portion.

Another significant patent is "Silver halide emulsions with doped epitaxy." This invention discloses a photographic silver halide emulsion comprised of radiation-sensitive composite silver halide grains. The host grain portions account for at least 50 percent of the total silver, with surface portions epitaxially deposited on the host grain portions. The epitaxially deposited surface portions exhibit a face-centered cubic crystal lattice structure containing a hexacoordination complex of a metal from periods 4, 5, and 6 of groups 3 to 14 of the periodic table.
