Modeling Compositional Heterogeneity

Compositional Modeling of Wax Formation in Petroleum Mixtures

Heavy organics deposition is a common problem in oil industry, especially in oil production, transportation and processing. Wax or solid paraffin series are examples of heavy organics that deposit. Precipitation and crystallization of wax causes major difficulties in different processes. Based on multi-solid theory, a basic model is modified in this paper for wax precipitation in different oils...

Identifying Compositional Heterogeneity in Mars’ Nili

Introduction: Spectral anomalies in Nili Patera, a central caldera of the Syrtis Major shield volcano, were first observed by [1] using Thermal Emission Spectrometer (TES) data. With the advent of data from the Thermal Emission Imaging Spectrometer (THEMIS), it is now possible to explore in greater detail the nature of the volcanic materials that give rise to both spectral and spatial anomalies...

Hierarchical Unilamellar Vesicles of Controlled Compositional Heterogeneity

Eukaryotic life contains hierarchical vesicular architectures (i.e. organelles) that are crucial for material production and trafficking, information storage and access, as well as energy production. In order to perform specific tasks, these compartments differ among each other in their membrane composition and their internal cargo and also differ from the cell membrane and the cytosol. Man-mad...

Compositional Receptor Modeling

Receptor models apportion an ambient mixture of pollutants to the contributing pollution sources. Often, neither the number of sources nor their chemical profiles are known precisely. The dual goals of modeling are to estimate the chemical “signature” of the sources, and to characterize the mixing process. I develop a novel modeling approach for receptor data where all model components are comp...
