Graphite bet surface area
Brunauer–Emmett–Teller (BET) theory aims to explain the physical adsorption of gas molecules on a solid surface and serves as the basis for an important analysis technique for the measurement of the specific surface area of materials. The observations are very often referred to as physical adsorption or … See more The concept of the theory is an extension of the Langmuir theory, which is a theory for monolayer molecular adsorption, to multilayer adsorption with the following hypotheses: 1. gas … See more It is still not clear on how to find the linear range of the BET plot for microporous materials in a way that reduces any subjectivity in the assessment of the monolayer capacity. A crowd-sourced study involving 61 research groups has shown that … See more The BET theory can be derived similarly to the Langmuir theory, but by considering multilayered gas molecule adsorption, where it is not required for a layer to be completed before an upper layer formation starts. Furthermore, the authors made five assumptions: See more Cement and concrete The rate of curing of concrete depends on the fineness of the cement and of the components used … See more • Adsorption • Capillary condensation • Langmuir adsorption model See more WebGraphite consists of three software components: carbon - a high-performance service that listens for time-series data. whisper - a simple database library for storing time-series …
