Ion Pairing in Aqueous Metal Sulfates and Platinum Group Metal Ammonium Solutions by Matthews, Richard P

“…The formation of ion pairs disrupts the solvent structure where the hydration shells about the bivalent hexachlorometallates are more affected compared with the trivalent hexachlorometallates and these first shell waters in turn are more affected than those in the bivalent tetrachlorometallates. …”

The inertisation of the zeolites ZSM-5, mordenite and beta by chemical vapour deposition using tetraethoxysilane by Weber, Reinier Willem, Weber, Reinier Willem

“…The silica layer can also narrow the pore openings uniformly, thus increasing the shape selective properties of the zeolites even more. By implication, coating ZSM-5 in a shell of iso-structural Silicalite-1 may provide an inert layer around the ZSM-5 crystals, without necessarily altering the pore opening size. …”

The interaction of acidification and warming on the South African abalone, Haliotis midae, and the potential for mitigation in aquaculture by Lester, Nina Catherine

“…Warming conditions were within the thermal optimum ranges for H. midae and did not significantly affect abalone growth; however warming did bring about significant changes in Condition Factor, shell shape, and strength over time and shifted acid-base regulation towards a more stable status. …”

Shadows of a Schwarzschild Black Hole Surrounded by a Spherically Symmetric Dark Matter by Ibrahim, Ahmad

“…In this thesis, using general relativity, the null geodesics and black hole shadow of a spherically symmetric configuration of a black hole (surrounded by a dark matter shell) are studied. First, the standard results of the photon sphere of Schwarzschild de-Sitter black hole is revisited and analyzed more carefully. …”
