The Effect of the Chemical Composition of Low Salinity Water on the Growth, Development, and Survival of Cultured Juvenile Blue Crabs
… in low salinity water containing various compositions of ions. ~rabs were isolated in separate containers and placed in thirty gallon aquaria containing 2ppt of ion solution. Temperature, ambient, humidity, and nitrite levels were monitored daily. Molts were measured to determine growth, and molt …

The investigation of the effect of free organic anions on scale inhibitors used to prevent nucleation occurring in oil rig wells, using dynamic test equipment.
When soluble salts in water come out of solution a precipitate forms. If this precipitate adheres to the walls of a pipe then scaling will occur. This big problem in the oil industry is solved by the use of scale inhibitors. The Gryphon oil field suffers from severe scaling problems. The oil from …

Microfluidic platforms for solid form screening of pharmaceutical parent compounds
Solid form screening and selection of pharmaceutical parent compounds (PCs) has been identified as a critical step in the early stages of drug development. A significant fraction of candidate PCs are rejected on account of poor physicochemical properties that affect their biopharmaceutical …

Quenching of porous silicon photoluminescence by deposition of metal adsorbates
Luminescent porous silicon is formed by anodization of silicon in HF acid in the dark and then under UV illumination. When illuminated with UV, samples exhibit a bright orange photoluminescence with a quantum efficiency of order a few percent. Porous silicon is characterized as a very complex …

Synthesis and characterisation of low-cost biopolymeric/mineral composite systems and evaluation of their potential application for heavy metal removal
Heavy metal pollution and waste management are two major environmental problems faced in the world today. Anthropogenic sources of heavy metals, especially effluent from industries, are serious environmental and health concerns by polluting surface and ground waters. Similarly, on a global scale, …

The kinetics of successive aquation reactions of tetraamminepalladium (II) ion
Solutions of tetraamminepalladium (II) perchlorate were made up and analyzed. The following acid hydrolysis reactions of tetraamminepalladium (II) ion were studied by ultraviolet spectroscopy. First order rate constants were evaluated for each step of the reaction series at various temperatures. …
