Abstract: In some embodiments, the present disclosure pertains to methods of removing heteroatoms from a fluid by associating the fluid with one or more adsorbents, where the association results in the removal of the heteroatoms from the fluid. The association may occur by associating the fluid with a single adsorbent or a plurality of adsorbents in a sequential manner that maximizes heteroatom removal efficacy. The methods may be utilized to remove heteroatom-containing compounds from various fluids, such as fuels, hydrocarbons, alcohols, water, organic solvents, and combinations thereof. The one or more adsorbents may include, without limitation, activated carbon, zeolites, ion exchanged zeolites, ion impregnated zeolites, alumina, alumina nanowires, carbon-based supports, and combinations thereof. The methods of the present disclosure can be utilized to reduce heteroatoms in the fluid by more than about 50%, by more than about 80%, or by more than about 99%.

Abstract: A method and apparatus for the analysis of magnified video image data to develop quantitative functional and morphological indices for cell-to-cell adhesion. Such induces permit distinction between different adhesion modalities and identification of various adhesion pathways of cells, for example lymphocytes time resolved measurements can also be done to track individual cells or cell clusters.
