Synthesis Of Some Chromium (Iii) Complexes And The Use Of These Complexes As Catalyst For The Polymerization Of Alpha-Olefins / Che Ibrahim Bin Abdullah, Che Ibrahim Abdullah

Student Works (2010-2019)

A series of chromium(III) and chromium(III)-iron(III) carboxylate complexes were prepared by heating common chromium(III) and Iron(III) salts in carboxylic acids. The structure of these complexes has been confirmed by X-ray crystallography to give a trinuclear oxo-centred carboxylate. The characterization of complexes was carried out by UV-visible spectroscopy, IR spectroscopy, Thermal analysis (TGA), CHN-elemental analysis and metal content analysis. The complexes contain a triangular arrangement of metal ions connected by a central μ3-oxo atom and bridged with six carboxylate ligands. Each carboxylate anion spans two metal centres at the periphery of the [M3(μ3-O)]6+ core, while H2O ligands occupy the remaining coordination …

The growth of the freshwater prawn industry has not reached its great heights compared to the marine shrimps because of agriculturists’ innate fear of disease that will hamper the growth of the industry. High concentrations of infectious microorganisms (yeast, viruses and bacteria) in crustaceans during hot and cool seasons have resulted in a huge decline in prawn farming. Vibriosis, early mortality syndrome (EMS) and gastroenteritis due to zoonotic outbreaks have been a major threat to the rapid expanding production of freshwater prawns. The innate immune defense which leads to a lot of possible solutions needs to be thoroughly investigated for …

Heart diseases are the leading cause of death worldwide. Despite the development of a broad array of treatment options, current therapies only delay progression of the disease and failed to prevent myocardial scar formation and replace the lost cardiomyocytes (cardiac muscle cells). Over the past decade the use of adult stem cells, particularly bone marrow derived mesenchymal stem cells, to safely facilitate recovery of cardiac function after myocardial infarction has received a lot of interest. Mesenchymal stem cells (MSCs), which are adherent stromal cells of a non-hematopoietic origin, have great differentiation potential and under appropriate in vitro culture conditions can …

Student Works (2010-2019)

Coral reefs that occur in Malaysia are of global significance, and an important resource for the sustainable development of the country. One key step taken to conserve the coral reef resources in Malaysia, was the establishment of Fisheries Prohibited Areas (FPAs). Unfortunately, coral reef management measures are virtually non-existent at these areas, exposing the reefs to many pressures driven by the rapid development of the adjacent coastal areas. The limited understanding of the true economic value of coral reef ecosystems, is the main reason that sufficient resources are not appropriated and to manage and conserve this fragile yet important resource. …
