The thesis is made up by four studies, on the comprehensive theme of integrated and subject specific science education in school. A literature study on the matter is followed by an expert survey, then a case study and ending with two analyses
One dimensional silicon nanomaterials has become more and more popular for optoelectronic, chemical and bio-chemical devices due to their semi-conducting ability and convenience for chemical modification by different chemical species. In order to achieve these purposes, many efforts have been input to the synthesis of silicon nanowires (SiNWs).
Bacteria from the genus Acidithiobacillus are often associated with biominingand acid mine drainage. Biomining utilises acidophilic, sulphur and ironoxidising microorganisms for recovery of metals from sulphidic low grade oresand concentrates. Acid mine drainage results in acidification and contaminationwith metals of soil and
Biofilms enable food-borne pathogens to resist removal from surfaces and survive disinfection. Biofilms of pathogens [e.g., S. enterica Serovar Typhimurium DT104 (STDT104)] formed on various surface types were probed with Calcofluor (b-D-glucan-specific ) and lectins… Contents Chapter 1: FOOD-BORNE PATHOGENS AND BIOFILMS
Life is a thing taken for granted by most. However, it is the life-long quest of many to unravel the mysteries of it. Understanding and characterizing the incomprehensively complex molecular interaction networks within a biological organism, which defines that organism, is a
The red tide organism Chattonella marina (Raphidophyceae) has been associated with fish kills, leading to serious economic losses and posing a significant ecological risk to marine biota. The precise toxic actions of these algae remain unclear, but there is growing scientific evidence
Full Title: Studies of key enzymes involved in the assembly of the tetrapyrroles The structurally related tetrapyrrolic pigments are a group of natural products that include the haems, the chlorophylls, and the corrinoids. These compounds participate in many of the fundamental biosynthetic
Lead-tin telluride alloy, Pb1-xSnxTe, is a narrow band gap group IV–VI semiconductor with NaCl-like crystalline structure. This material has interesting electronic properties, which makes it suitable for designing infrared photo detectors, diode lasers, and thermo-photovoltaic energy converters. In this project, we used
The reactivity of some osmium complexes containing salchda ligands (salchda = N,N’-bis(salicylidene)- o-cyclohexyldiamine) has been investigated. The contents are divided into three main parts. In part I, the reactivity of osmium(VI) nitrido complexes containing salchda ligands towards various nucleophiles such as amines
For the last decade, one dimensional growth of materials was highly developed. Carbon nanotubes was first synthesized, other nanotubes, nanowires and nanorods were fabricated afterwards. Other than the synthesis, the properties of one dimensional materials were extremely investigated. It was found that
