Carbons, Zeolites and Molecular Sieves: Material Characteristics and Solutions for Characterization

Material characteristics and solutions for characterization. Activated and porous carbons along with zeolites and molecular sieves largely owe their industrial value to the ability to control the rate of transport of different molecules. This characteristic gives rise to a broad range of applications in gas separation, catalysis, the selective adsorption of pollutants and ion exchange.…

Micromeritics Role in the Development of DFT

In April 1993, Micromeritics introduced a software package called DFT V1.00. This program was the first commercial offering of a practical method to routinely analyze experimental adsorption isotherms using methods based on modern theoretical physical chemistry. It was the culmination of an investigation by James P. Olivier and William B. Conklin into a method by…
