Full textThis thesis reports an investigation of how acid-base models are taught and understood in Swedish upper secondary school. The definition of the concepts of acids and bases has evolved from a phenomenological level to an abstract (particle) level. Several models of acids and bases are introduced in Swedish secondary school. Among them an ancient model, the Arrhenius model and the Brønsted model. The aim of this study was to determine how teachers handle these models in their teaching. Further, to investigate Swedish upper secondary students’ ideas about the role of chemistry models, in general, and more specific, of models of acids and bases. The study consisted of two parts. First, a study was performed to get an overview of how acids and bases are taught and understood in Swedish upper secondary schools. It consisted of three steps: (i) the most widely used chemistry textbooks for upper secondary school in Sweden were analysed, (ii) six chemistry teachers were interviewed, and, (iii) finally also seven upper secondary school students were interviewed. The results from this study were used in the second part which consisted of two steps: (i) nine chemistry teachers were interviewed regarding their pedagogical content knowledge (PCK) of teaching acids and bases, and (ii) a questionnaire was administered among chemistry teachers of 441 upper secondary schools in Sweden. The results from the interviews show that only a few teachers chose to emphasise the different models of acids and bases. Most of the teachers thought it was sufficient to distinguish clearly between the phenomenological level and the particle level. In the analysis of the questionnaire three subgroups of teachers were identified. Swedish upper secondary chemistry teachers, on the whole, had a strong belief in the Brønsted model of acids and bases. However, in subgroup one (47 %) teachers’ knowledge of how the Brønsted model differs from older models was limited and diverse. Teachers in subgroup two (38 %) and three (15 %) seemed to understand the differences between the Brønsted model and older models, but teachers in subgroup 2 did not explain the history of the development of acids and bases in their teaching. Instead they (as teachers in subgroup one) relied more on the content in the textbooks than teachers in the third subgroup. Implications for textbook writers, teaching, and further research are discussed.

Full textENGLISH ABSTRACT: In this thesis the synthesis of a range of model and siloxane functionalized salicylaldimine ligands and [N-(n-propyl)-(2-pyridyl)] diimine ligands are described. The functionalized ligands were obtained by the reaction of salicylaldehyde and 2-pyridinecarboxaldehyde with 3-aminopropyltriethyoxysilane. All ligands were characterized by FT-IR and 1H NMR spectroscopy. The salicylaldimine ligands were reacted with either Cu(II) or Pd(II) salts to form both the model and functionalized Cu(II) and Pd(II) complexes. The Cu(II) complexes were characterized using FT-IR, EPR and UV-VIS spectroscopy while the Pd(II) complexes were characterized using FT-IR, 1H NMR and 13C{1H} NMR spectroscopy. The diimine ligands were reacted with Cu(II) salts to form functionalized pyridinyl complexes which were characterized used FT-IR spectroscopy. Two mesoporous silica supports, MCM-41 and SBA-15 were synthesized. The siloxane functionalized salicylaldimine Cu(II) and Pd(II) complexes were immobilized onto these supports to produce heterogenized catalysts. These catalysts were characterized using a range of solid-state techniques: BET nitrogen adsorption/desorption, scanning electron microscopy (SEM), thermal gravimetric analysis (TGA), ICP-AES, and powder X-ray diffraction (XRD) analysis. The powder XRD and SEM analysis showed that the structural integrity of the catalyst supports was kept intact during the immobilization process. BET analysis and ICP-AES showed that the complexes had been attached to the silica supports. Both the model complexes and heterogenized catalyst systems were tested in the oxidation of benzyl alcohol to benzaldehyde. The model copper catalyst showed high activity in this reaction with molecular oxygen used as oxidant and the (2,2,6,6-tetramethylpiperidin-1-yl)oxyl radical as co-oxidant. The immobilized copper complexes showed low activity in the same reaction. This was attributed to steric hindrance around the active site dye to its entrapment with the silica matrix thus hindering the formation of a key intermediate in the oxidation cycle due to steric hindrance. The palladium complexes were not active in the oxidation reaction when molecular oxygen was used as oxidant, but showed slight activity when hydrogen peroxide was used.
AFRIKAANSE OPSOMMING: In hierdie tesis word die sintese van ‘n reeks model sowel as gefunksioneerde salisielaldemien ligande en [N-(n-propiel)-(2-piridiel)] di-imien ligande beskryf. Die gefunksioneerde ligande is verkry deur die reaksie van salisielaldehied en en 2-piridienaldehied met 3-aminopropieltriëtoksiesilaan. Al die ligande is gekarakteriseer deur FT-IR en 1H-KMR spektroskopie. Die salisielaldimien ligande is met óf Cu(II) óf Pd(II) soute reageer om beide die model en gefunksioneerde Cu(II) en Pd(II) komplekse te vorm. Die Cu(II) komplekse is gekarakteriseer deur FT-IR, EPR en UV-Vis spektroskopie terwyl die Pd(II) komplekse deur FT-IR, 1H-KMR en 13C{1H}-KMR spektroskopie gekarakteriseer is. Die di-imien ligande is met Cu(II) soute reageer om gefunksioneerde piridinielkompekse te vorm wat deur FT-IR spektroskopie gekarakteriseer is. Twee mesoporeuse silika draers, MCM-41 en SBA-15 is gesintetiseer. Die siloksaan-gefunksioneerde salisielaldemien Cu(II) en Pd(II) komplekse is op hierdie draers geimobiliseer om geheterogeniseerde katalisatore te vorm. Hierdie katalisatore is gekarakteriseer deur van ‘n wye reeks vaste toestand tegnieke gebruik te maak: BET stikstof adsorpsie/desorpsie, skandeer elektron mikroskopie (SEM), termiese gravimetriese analise (TGA), ICP-AES en poeier-XRD analise. Die poeier-XRD en SEM analisies het aangetoon dat die strukturele integriteit van die katalisator draers behoue gebly het tydens die immobiliseringsproses. BET analise en ICP-AES het aangetoon dat die komplekse aan die silika draers geheg is. Beide die model komplekse en geimobiliseerde katalisators is getoets in die oksidasie van bensielalkohol na bensaldehied. Die model Cu(II) katalisator het hoë aktiwiteit in hierdie reaksie getoon met molekulêre suurstof as oksideermiddel en die (2,2,6,6-tetrametielpipiridien-1-iel)oksiel radikaal as ko-oksideermiddel. Die geimobiliseerde Cu(II) komplekse het lae aktiwiteit in dieselfde reaksie getoon. Dit is toegeskryf aan steriese hindernis rondom die aktiewe sentrum as gevolg van die verstrikking binne die silika matrys, wat die vorming van ‘n belangrike tussentoestand in die oksidasie-siklus verhinder. Die Pd(II) komplekse was nie aktief in die oksidasie-reaksie in die geval waar molekulêre suurstof as oksideermiddel gebruik is nie, maar het effense aktiwiteit getoon waneer waterstofperoksied gebruik is.

Full textSince the classic Miller experiment in 1953 evidencing the amino acids formation under early Earth conditions, the chemistry of the prebiotic period is still very discussed. It is cited, for example, the role of sulfocyanic theory, which describes the origin of organic molecules from sulfur-containing compounds such as ammonium thiocyanate (NH4SCN). In this context, this thesis shows a study about the investigation of NH4SCN in prebiotic conditions. Thereby, experiments of electrochemical oxidation and ultraviolet (UV) irradiation were carried out with samples containing NH4SCN in different experimental conditions. By using electrochemistry coupled to Fourier transform infrared spectroscopy (FTIR in situ), the dimer thiocyanogen (SCN)2 was identified as the first oxidation product of NH4SCN, which is a recognized precursor of the oligomers from prebiotic period. In counterpart, UV irradiation of the NH4SCN led to the formation of orthorhombic sulfur (S8) and the nitrogenous bases 4-(3H)-pyrimidinone, cytosine, adenine and purine, besides other molecules. Probably, hydrogen cyanide (HCN) is one of the precursors of the biomolecules abovementioned, contradicting a possible route via (SCN)2. The results of this study also reinforce the hypothesis that there is no direct formation of amino acids by irradiation of NH4SCN. Thus, it is proposed here that the formation of DNA blocks, the nitrogenous bases, can also be inserted in the context of sulfocyanic theory.

Full textWhile production of Portland cement is made the extraction of non-renewable raw materials and the release of CO2 excessively; the manufacture of alkali activated cement does not involve the calcination of materials and can be used as raw material byproducts of industry. In this context, the alkali activated cements emerge as a new class of binder materials of good performance and low environmental impact, which can be synthesized only with waste, such as slag in blast furnace activated with different alkalis generating materials with characteristics interesting for applications in construction. Depending on the chemical composition, blast furnace slag generated in coke ovens are used as addition to Portland cement; however, those from charcoal ovens are not the same destination as usually is inappropriate the basicity modules prescribed in the rules, thus implying an environmental liability. This research has the purpose to obtain activated alkali cements (CAT) aimed at the valorisation of the slag (acid). Also used was a blast furnace from coke (B) as raw material, in order to compare the chemical composition of both. CAT initial compositions with sodium hydroxide was prepared (NaOH) as an activator, which were subjected to two curing processes (wet and immersed) for initial testing. The immersed cure was less benign in the use of slag as a binder caused a lower compressive strenght, since the contact with the water solubilizing the material reducing its contact surface. In wet cure, with 5% NaOH as an activator, the slag mortars A obtained high mechanical performance, arriving values close to 45MPa at 28 days; the development of C-S-H and hydrotalcite phase was observed from the XRD patterns of X-rays and thermal analysis. Slag B developed less strenght in the presence of the activator, but the same phases were observed in both compositions. It was possible to verify that the chemical composition of raw material had strong influence on the performance of the CAT’s.

Full textComplexos de íons lantanídeos luminescentes tem se destacado em marcação biológica em função de sua alta eficiência de emissão atribuída ao “efeito antena”. A incorporação destes complexos em matrizes inorgânicas leva a formação de materiais híbridos orgânico-inorgânicos. Esse híbrido pode ser utilizado como marcador em ensaios biológicos desde que acoplado a moléculas de reconhecimento específico, p.e., o sistema avidina-biotina. Neste trabalho foi descrita a síntese e a caracterização do ligante SalenHSi (um tipo de base de Schiff), dos complexos Er(SalenHSi) e Eu(SalenHSi) e dos seus respectivos híbridos com matriz de sílica gel para potencial utilização como marcadores. A formação do ligante, dos híbridos e dos híbridos aminofuncionalizados foi comprovada por FTIR. Dados de titulação complexométrica indicaram estequiometria 3:1 (ligante:metal) no complexo Eu(SalenHSi). O diagrama de níveis de energia construído demonstrou a viabilidade de transferência de energia do ligante para os íons Eu 3+ e Er 3+ . O complexo de Er 3+ não é um bom emissor no visível, mas o de Eu 3+ apresenta emissão no vermelho devido as seguintes transições: 5 D0→ 7 FJ (J = 0, 1, 2, 3 e 4), sendo uma única transição 5 D0→ 7 F0 indicando a presença de somente um sítio emissor sem centro de inversão. Os parâmetros Ω 2, Ω 4, R 02 e os valores de τ e η foram determinados para o complexo Eu(SalenHSi) e a eficiência quântica estimada foi de 9,62%. Imagens de microscopia eletrônica de varredura indicaram uma modificação na morfologia dos complexos em função das formas de acondicionamento das amostras. Os testes preliminares de conjugação realizados com o híbrido aminofuncionalizado contendo Eu 3+ , a proteína albumina e um crosslinker foram acompanhados por espectroscopia de absorção na região do UV-Vis, e os resultados obtidos demonstram uma efetiva conjugação
Luminescent complexes of lanthanide ions have been applied in biological labeling because of their high emission efficiency assigned to the antenna effect. The incorporation of these complexes in inorganic materials leads to the formation of organic-inorganic hybrid materials. Such material may be used in biological assays once it is coupled to specific molecules, i.e., the avidin-biotin system. This work describes the synthesis and characterization of the ligand SalenHSi (a type of Schiff base), the complex Er(SalenHSi) and Eu(SalenHSi) and their hybrids with silica gel matrix for potential use as biological labels. The formation of ligand, hybrids and hybrids aminofunctionalized was confirmed by FTIR. Complexometric titration data, and elementary analysis indicated the stoichiometry 3:1 (ligand:metal) for the complexes I. The energy level diagram demonstrated the feasibility of energy transfer from the ligand to Eu 3+ and Er 3+ ions. Spectroscopic studies performed indicated that Er 3+ complex do not emit in the visible, on the other hand the Eu 3+ complex exhibit red emission the following transitions: 5 D0 → 7 FJ (J = 0, 1, 2, 3 and 4). The only 5 D0 → 7 F0 transition indicates the presence of a single site without inversion center. Yet for Eu(SalenHSi) was determined the Ω2 , Ω4, R 02 parameters and the values of τ and η, and the quantum efficiency value estimated as 9.62%. Images of scanning electron microscopy indicated a change in the morphology of the complex as a function of the storage forms of samples. Preliminary tests performed with the combination of the aminofunctionalized hybrid containing Eu 3+ , the albumin protein and crosslinker were accompanied by absorption spectroscopy in the UV-Vis and the results suggest the effectiveness of the conjugation, opening precedents for future testing by using the self-recognition system avidin-biotin
