Development and performance characterization of first-generation dendrimeric nanofiltration membranes
… organic matter while allowing passage of inorganic salts. In this project, seven distinct novel first generation (G1) NF polyamide membranes have been developed and studied to understand their rejecting capability against selected organic surrogate, Rhodamine-WT (R-WT), and inorganic …

Exploring the Influence of structural variation on the solution and solid-state behaviour of cyanine
… aggregates with and without the presence of inorganic salts. The aggregation process of several trimethine dyes was found to be accelerated by the anion of inorganic salts with di- and trivalent anions being more efficient than monovalent anions. Simple oxygen containing dyes were found not …

Electrophilic C(sp²)–H Cyanation with Inorganic Cyanate (OCN⁻) by Pᴵᴵᴵ/Pⱽ=O-Catalyzed Phase Transfer Activation
… show that under solid-liquid phase transfer, an inorganic cyanate is activated by halide displacement on a halophosphonium. Redox catalysis is enabled by the usage of a strained phosphine (phosphetane) so that catalyst turnover from phosphine oxide to phosphine can be easily achieved by the usage …

Aromatic acetals : their synthesis and alkylation
… available comparing the sulfonic acids with the inorganic salts and mineral acids. For that reason one of the subsidiary problems of this investigation was such a comparison.</p><p>In order to investigate stability, several acetals were subjected to conditions intended to produce ring …

Impact of molasses quality on ethyl alcohol fermentation by the yeast saccharomyces cerevisiae
… Additionally, elevated concentrations of inorganic salts and ionic strength in industrial fermentation media have been implicated in negatively affecting fermentation. Based on these limited literature findings, the study addressed the effect of three cation constituents of molasses (K+, …

Fast Identification of Components Commonly Used in Homemade Explosives by Spectroscopic and Chemometric Methods
… and classification of common fuel sources and inorganic salts used as oxidants. Additional quantification research was performed to determine limits of detection for adulterated fuels and oxidant mixtures using partial least squares regression (PLS-R). We have demonstrated that spectroscopic …

Thermodynamic design and fouling of membrane distillation systems
… fouling, a study on heterogeneous nucleation of inorganic salts with a fouling regime map to avoid nucleation, and fouling prevention via induced air-layers.

On the reactions of ortho-positronium and inhibition of positronium formation
… of ortho-positronium with a variety of inorganic and organic compounds was undertaken to investigate the mechanisms of the thermal reactions of ortho-positronium and to investigate the processes which inhibit positronium formation. It was found that the rate constants for the reaction of …

The inclusivity of ice.
… of a modified-Czochralski freezing method with inorganic salts, such as sodium chloride, ammonium chloride, and ammonium sulfate; organic salts, such as sodium acetate, sodium formate, and ammonium acetate; as well as the volatile molecule, tetrahydrofuran. In Chapter Three and Four, it was …

A Study of Lead Alkylation in Natural Systems
… toxic to the higher forms of life than their inorganic counterparts. Following the discovery that microorganisms on sediment sludges are capable of methylating inorganic salts of mercury to the neurotoxin methylmercury, a great deal of attention has been focussed upon the biological …

Hall effect in printed Nanoparticulate Silicon Networks
… nanoparticulate silicon ink, doped with inorganic salts, which is a different procedure to conventional impurity doping of the silicon structure, was produced with linseed oil. A home-built Hall measurement system was used to characterise layers of doped ink, for which a complete carrier …

Hydrometallurgical Processing Of Rare Earth Elements From Ion Adsorption Clays
… cost and less environmental impact. A series of inorganic salts with different concentrations were employed to leach the Ion-adsorption rare earth agglomerates, and the relationship between the leaching efficiency of rare earth and reagent type was investigated in unagitated systems. This study …

Treatment of a multicomponent mining effluent using calcium hydroxide in a fluidized bed crystallizer
… by high concentrations of dissolved inorganic salts are often disposed in evaporation ponds, which promotes the risk of ground water pollution and land wastage. Moreover, this forfeits the potential benefits of valuable salts recovered. The aim of this project was to investigate the …

Comparisons of crop yields using semi-organic and inorganic fertilizers
… fertilizer is compared to the more widely used inorganic type. A semi-organic fertilizer contains a base of organic materials to which is added a mixture of inorganic salts to make up a suitable analysis. The results from three years field trials and certain greenhouse experiments are presented. …

Calixarene and coordination complex hosts for anions.
… from methanol solution or in presence of inorganic salts. Thermoanalysis shows that all the modifications melt without previous transition and applying the heat of fusion rule proves this system to be completely monotropic. The crystal structures show that the molecule forms one …
