Nowadays, it is commonly accepted that the World-Wide Web is the most popular tool for sharing knowledge and information (Berners-Lee, 1996). However, there is a huge and growing amount of information and it is getting more and more difficult to make sense out of it. The research work presented in this paper is an effort to address this Overload Information problem (Gross, 1964). The main propo...

Abstract Corundum with inclusions of enigmatic super-reduced minerals was found in mineral separates received as a result alluvial sediment exploration near Mt Carmel, Israel by the Shefa Yamim Company. This corundum, registered ‘Carmel sapphire TM ’, has been an object numerous publications W. Griffin's scientific team, which they propose questionable hypothesis formation at crust–mantle bound...

Three different crystal forms were obtained from the crystallisation of a flexible imidazole based ligand and CdBr(2) under different conditions. Structural analysis reveals that the correlation between the three metallocyclic compounds can be described in terms of isostructurality, solvatomorphism and supramolecular isomerism.

A scalable, transferable, cooling crystallisation route to the elusive, metastable, form II of the API acetaminophen (paracetamol) has been developed using a multicomponent "templating" approach, delivering 100% polymorphic phase pure form II at scales up to 120 g. Favourable solubility and stability properties are found for the form II samples.

Carbonatites host Earth’s main REE deposits, with bastnaesite (LREE)CO 3 F being the economic REE-bearing mineral. However, mineralisation processes are debated between hydrothermal or magmatic origin. This study aims to assess if can be magmatic, and characterise behaviour during carbonatite crystallisation. Crystallisation experiments have been performed from 900 600 °C at 1 kbar, on a REE-ri...
