    Abstract: Environmental challenges and high cost of fossil fuel has made Biodiesel gained more recognition as alternative fuel. In this study, heterogeneous catalyst was developed via dealumination of Ukpor clay and calcined snail shells. Basicity, morphology, textural characteristics among other properties of catalyst were studied using XRF, FTIR, SEM, XRD,... Show More

    Abstract: Bulk crystal growth technologies originate from the Czochralski (CZ) and Vertical Bridgman (VB) methods developed almost one century ago. Both methods were applied to prepare single crystals of many kind of inorganic materials, for example, semiconductors, halides and many oxides. In the VB process, molten raw materials are wetting the crucible wal... Show More
