Saini, Vipin K.; Pires, Joao – Journal of Chemical Education, 2012
Nanoporous zeolite foam is an interesting crystalline material with an open-cell microcellular structure, similar to polyurethane foam (PUF). The aluminosilicate structure of this material has a large surface area, extended porosity, and mechanical strength. Owing to these properties, this material is suitable for industrial applications such as…

Bresler, Marc R.; Hagen, John P. – Journal of Chemical Education, 2008
Many physical chemistry lab courses include an experiment in which students measure surface tension as a function of surfactant concentration. In the traditional experiment, the data are fit to the Gibbs isotherm to determine the molar area for the surfactant, and the critical micelle concentration is used to calculate the Gibbs energy of micelle…

Mattson, Bruce; Foster, Wendy; Greimann, Jaclyn; Hoette, Trisha; Le, Nhu; Mirich, Anne; Wankum, Shanna; Cabri, Ann; Reichenbacher, Claire; Schwanke, Erika – Journal of Chemical Education, 2013
The hydrogenation of alkenes by heterogeneous catalysts has been studied for 80 years. The foundational mechanism was proposed by Horiuti and Polanyi in 1934 and consists of three steps: (i) alkene adsorption on the surface of the hydrogenated metal catalyst, (ii) hydrogen migration to the beta-carbon of the alkene with formation of a delta-bond…

Talukdar, Partha Pratim – ProQuest LLC, 2010
The variety and complexity of potentially-related data resources available for querying--webpages, databases, data warehouses--has been growing ever more rapidly. There is a growing need to pose integrative queries "across" multiple such sources, exploiting foreign keys and other means of interlinking data to merge information from diverse…

Schuttlefield, Jennifer D.; Grassian, Vicki H. – Journal of Chemical Education, 2008
Attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy is a useful technique for measuring the infrared spectra of solids and liquids as well as probing adsorption on particle surfaces. Several examples of the use of FTIR-ATR spectroscopy in different undergraduate chemistry laboratory courses are presented here. These…

Sumida, Kenji; Arnold, John – Journal of Chemical Education, 2011
Metal-organic frameworks (MOFs) are crystalline materials that are composed of an infinite array of metal nodes (single ions or clusters) linked to one another by polyfunctional organic compounds. Because of their extraordinary surface areas and high degree of control over the physical and chemical properties, these materials have received much…

Wankat, Phil – Chemical Engineering Education, 2009
Separations have played a major role in the history of chemical engineering and will continue to be important. Since separations have always been a major cost item in the process industries, they have always been a critical key to successful commercialization. First, while reviewing the history of separation processes we will observe that many…

Cooke, Jason; Henderson, Eric J. – Journal of Chemical Education, 2009
Experiments are presented that demonstrate the size-exclusion properties of zeolites and reveal the reason for naming zeolites "molecular sieves". If an IR spectrometer is available, the adsorption or exclusion of alcohols of varying sizes from dichloromethane or chloroform solutions can be readily demonstrated by monitoring changes in the…

Langseth, David E. – Journal of Geoscience Education, 2009
When teaching phase partitioning concepts for solutes in porous media, and other multi-phase environmental systems, explicitly tracking the environmental media phase with which a substance of interest (S0I) is associated can enhance the students' understanding of the fundamental concepts and derivations. It is common to explicitly track the…

Wankat, Phillip C. – Chemical Engineering Education, 1984
Discusses a simple method for following the movement of a solute in an adsorption or ion exchange system. This movement is used to study a variety of operational methods, including continuous flow and pulsed flow counter-current operations and simulated counter-current systems. Effect of changing thermodynamic variables is also considered. (JM)

Cooney, David O. – Chemical Engineering Education, 1987
Describes an experiment developed and used in the unit operations laboratory course at the University of Wyoming. Involves the liquid-phase adsorption of an organic compound from aqueous solution on activated carbon, and is relevant to adsorption processes in general. (TW)

Hwa, Rebecca; Weizman, Haim – Journal of Chemical Education, 2007
The separation of ferrocene and acetylferrocene by column chromatography is a widely used experiment in undergraduate organic labs. The experiment was expanded into a three-component mixture to increase the challenge of the experiment and to make TLC analysis necessary. (Contains 2 figures.)

Poce-Fatou, J. A.; Bethencourt-Nunez, M.; Moreno, C.; Pinto-Ganfornina, J. J.; Moreno-Dorado, F. J. – Journal of Chemical Education, 2008
This article presents a lab experience to study detergency from a physicochemical point of view intended for undergraduate students. By means of a simple experimental device, we analyze the influence of the surfactant concentration in both distilled water and tap water. Our method is based on the measurement of diffuse reflectances of polyester…
