Advantages of QSDFT for Pore Size Analysis of Carbons

Quenched solid density functional theory methods that take into account the heterogeneity / surface roughness of carbons were developed and validated and are available in the Anton Paar software for pore size analysis. Methods exist for varying pore geometry and examples for activated carbons, templated mesoporous carbons, and hierarchical carbons are given.

Graphene Characterization

Graphene and graphene-related materials have revolutionized numerous areas of materials science and technology. Their massive technological success is related to their unique structural and chemical properties. Graphene structure and key fundamental properties such as surface area, pore size, and density are examined.

Differentiating Filters/Membranes by Capillary Flow Porometry

Mechanical filters/membranes are devices that use porous media, such as paper, foams, synthetic fibers, cotton, or spun fiberglass, to remove solid particles and other contaminants in applications requiring clean streams of gases or liquids. The Porometer 3G series of instruments can measure and analyze the pore characteristics of materials used in different filtering applications from contaminant removal to medical devices and electronic fabrication. This application report compares and contrasts the results for two similar looking filters used to remove contaminants from an in-house air source.

Micropore Size Analysis of Porous Carbons Using CO2 Adsorption at 273.15 K (0 °C)

Activated carbons in the form of fibers, pellets, granules, and powders are used in air filters, water purification systems, for removing organic impurities from various solutions, as well as in a variety of medical, environmental, and agricultural applications. These highly microporous, high surface area materials are often characterized by their apparent BET surface area and their pore size distribution (PSD). Measuring the PSD of microporous samples using nitrogen or argon adsorption is a slow process, requiring very low vacuum levels that require an expensive turbomolecular pump. Alternatively the PSD can be determined quickly using carbon dioxide at 0°C, at higher pressures than using nitrogen or argon, thus increasing throughput and reducing the equipment cost.

Krypton Gas Adsorption for Thin Film Pore Size Analysis

Pore size distributions on thin films can be obtained using Krypton adsorption at 87 K. The pore size distributions are calculated using a calibrated method that is traceable to NLDFT. Silica and titania thin film measurements and corresponding pore size distributions at 87 K using Kr are discussed.
