Title: Gautam Bandyopadhyay: Innovator in Nuclear Waste Management and Electrochemical Cells

Introduction

Gautam Bandyopadhyay is a notable inventor based in Naperville, IL (US). He has made significant contributions to the fields of nuclear waste management and electrochemical cell technology. With a total of 2 patents, his work has had a meaningful impact on these critical areas.

Latest Patents

Bandyopadhyay's latest patents include a method for preparing nuclear wastes for transportation and interim storage. This innovative method involves forming nuclear waste into a substantially water-insoluble solid by mixing calcined waste with at least 10 weight percent powdered anhydrous sodium silicate. The mixture is then subjected to a high humidity environment, allowing for the formation of cementitious bonds through chemical reactions. This technique is particularly suitable for preparing an interim waste form from dried high-level radioactive wastes.

Another significant patent focuses on the preparation of porous, rigid ceramic separators for electrochemical cells. In this method, particles of ceramic material are calcined at temperatures above about 1200°C to reduce their sinterability. A non-calcined ceramic powder is blended with the original powder to control the porosity of the completed separator. The resulting ceramic blend is pressed into sheets of the desired shape and sintered at a temperature lower than the calcination temperature. This technique allows for the creation of separator sheets with a thickness of about 1 to 2.5 mm and porosity ranging from 30 to 70%. Ceramics such as yttria, magnesium oxide, and magnesium-aluminum oxide have been effectively used in this process.
