Title: Sandip Niyogi: Innovator in Carbon Nanotube Separation
Introduction
Sandip Niyogi is a prominent inventor based in Los Alamos, NM (US). He has made significant contributions to the field of nanotechnology, particularly in the separation of carbon nanotubes. His innovative approach has garnered attention in both academic and industrial circles.
Latest Patents
Niyogi holds a patent for the "Separation of carbon nanotubes into chirally enriched fractions." This patent describes a method for separating a mixture of single-walled carbon nanotubes (SWNTs) into fractions that are enriched in chirality. The process involves preparing an aqueous suspension of SWNTs and a surfactant, injecting a portion of this suspension onto a column of separation medium with a density gradient, and then centrifuging the column. In certain embodiments, salt is added before centrifugation, and in others, the centrifugation occurs at temperatures below room temperature. The resulting fractions separate as colored bands within the column, with the diameter of the separated SWNTs decreasing as the density increases along the gradient. These colored bands can be withdrawn separately from the column. Niyogi's work in this area has led to advancements in the manipulation and application of carbon nanotubes.
