Adsorbed natural gas (ANG) technology
Pfeifer, Peter; Suppes, Galen J.; Shah, Parag S.; Burress, Jacob W., 1983-; Pobst, Jeff (2010-10)This invention teaches a method of manufacturing carbon so that it adsorbs large amounts of gas at low pressures due to the high surface area and associated nanopores. For example, a full tank of this carbon can hold more ... -

Corn cob can be used to produce activated carbon because its organic origin is similar to coconut and peach pits which have ... -
Determination of saturated film densities and volumes for adsorbed hydrogen, and application to the calculation of the enthalpy of adsorption at room temperature
Knight, Ernest William (University of Missouri--Columbia, 2018)The development of high-performance materials for hydrogen storage by physical adsorption requires understanding of detailed microscopic properties of the adsorbed film. In this work, we show that adsorbed hydrogen films ... -
Dynamics of Gas Exchange through the Fractal Architecture of the Human Lung, Modeled as an Exactly Solvable Hierarchical Tree [abstract]
Mayo, Michael Louis, 1979-; Pfeifer, Peter; Gheorghiu, Stefan, 1971- (The Body Project, 2008)The acinar airways lie at the periphery of the human lung and are responsible for the transfer of oxygen from air to the blood during respiration. This transfer occurs by the diffusion-reaction of oxygen over the irregular ... -
The effects of particle size distribution on density of activated carbon [abstract]
Crockett, Sean; Pfeifer, Peter; Shah, Parag S. (University of Missouri--Columbia. Office of Undergraduate Research, 2006)Methane is one of many alternative fuels that have been explored over the past few years in an effort to reduce our dependency on fossil fuels. Currently, methane can be condensed and used as a fuel for most large vehicles. ... -
Enhanced hydrogen adsorption in boron substituted carbon nanospaces
Firlej, Lucyna; Roszak, Sz.; Kuchta, Bogdan; Pfeifer, Peter; Wexler, Carlos, 1966- (American Institute of Physics, 2009)Activated carbons are one of promising groups of materials for reversible storage of hydrogen by physisorption. However, the heat of hydrogen adsorption in such materials is relatively low, in the range of about 4-8 kJ/mol, ... -
