Abstract:

La combustion de biomasse dans des chaudières industrielles à grille produit plusieurs espèces polluantes dont les oxydes d'azote, aussi appelés NOx. Ces molécules sont nocives pour l'environnement (causes de pluies acides, gaz à effet de serre). Ces polluants sont majoritairement formés par l'oxydation de l'azote initialement contenu dans la biomasse. La limitation de leurs émissions est donc un enjeu important dans le domaine de la combustion de biomasse. Pour y parvenir, le recours à la modélisation est courant. La chimie de l'azote en phase gaz est bien connue ; la modélisation du devenir

Abstract:

Biobased diamines are excellent precursors for the synthesis of non-isocyanate polyurethanes (NIPUs). We have prepared several biobased diamines using three different reactions for their synthesis. In the first method, we have carried out chain elongation of cellulose-derived 2,5-diformylfuran by the Henry reaction followed by reduction of the nitroalkene. Yields of the key step: Hantzsch Ester reduction, were 70-80%. Method two involves the Friedel-Crafts alkylation of furfurylamine with different ketones under acidic conditions. Yields of large-scale alkylation reaction were 60-77%. In meth

Abstract:

The main objective of this thesis is to understand molecular crystallization as a multistep process with or without polymeric additives, including transient liquid-liquid phase separation, nanocrystal nucleation within the dense phase, and subsequent nanocrystal self-assembly or self-organization in sequence. The thesis starts with a quaternary model system, containing DL-Glutamic acid (Glu), polyethyleneimine (PEI), water, and EtOH, for the understanding of multistep precipitation of Glu with PEI as an additive. The experiments were performed by mixing Glu-PEI aqueous solution with a non-solv

Abstract:

I terremoti sono considerati una delle peggiori calamità naturali a causa del loro enorme impatto sulle vite e proprietà. La loro bassa prevedibilità è dovuta alla complessità del fenomeno e dall’impossibilità di accesso all’osservazione diretta della sorgente e dal parametro dello stress che non può essere misurato direttamente. Inoltre, la causalità, l’origine in faglie sconosciute e l’insorgere non sempre costante di eventuali precursori rendono il lavoro ancora più difficile. Di conseguenza, l’elevata incertezza associata alle loro previsioni, nonostante la grande quantità di dati sperimen

Abstract:

Models of Alzheimer’s disease (AD) have provided useful insights into the pathogenesis and mechanistic pathways that lead to its development. One emerging idea about AD is that it may be described as a hypometabolic disorder due to the reduction of glucose uptake in AD brains. Inappropriate processing of Amyloid Precursor Protein (APP) is considered central to the initiation and progression of the disease. Although the exact role of APP misprocessing is unclear, it may play a role in neuronal metabolism before the onset of neurodegeneration. To investigate the potential role of APP in neuronal

Abstract:

Nitric oxide (NO) is a neurotransmitter involved in memory processes. Currently, the only recognized physiological signalling pathway controlled by NO is the activation of guanylyl cyclase. In this thesis, we propose an alternative NO-signalling pathway that involves the Heme-regulated eukaryotic initiation factor-2a kinase (HRI) and eIF2a phosphorylation. We have found that the enzyme BACE1, a key protein in Alzheimer’s disease (AD), is controlled by this novel pathway. This pathway would be involved in the physiology of memory formation and learning processes. We have also studied how

Abstract:

Haloacetic acids (HAAs) are a group of disinfection by-products (DBPs) found in drinking water which are regulated in the USA but not yet in the EU. Epidemiology tests have shown that they may have carcinogenic and mutagenic effects on human beings. HAAs are produced during the disinfection process from the use of chlorination and they may persist during water distribution and finally reach the customers’ tap at concentrations of concern. The formation of HAAs arises from the reaction between precursor material – principally natural organic matter (NOM) – and chlorine, and the species and amou

Abstract:

Metal oxide thin films serve as critical components in many modern technologies, including microelectronic devices. Industrial state-of-the-art production utilizes vapor-phase techniques to make high-quality (dense, smooth, uniform) thin film materials. However, vapor-phase techniques require large energy inputs and expensive equipment and precursors. Solution-phase routes to metal oxides have attracted great interest as cost-effective alternatives to vapor-phase methods and also offer the potential of large-area coverage, facile control of metal composition, and low-temperature processing.

Abstract:

Cells in the body respond to mechanical loads in ways that are crucial to normal and disease physiology. Understanding these processes is difficult due to the complex mechanical environment in vivo. In this research, we have developed several cell-stretching devices capable of subjecting cell cultures to non-uniform stretch distributions in order to investigate pathological responses of vascular smooth muscle cells to physiologic stretches. 10T1/2 cells were cyclically stretched with these devices for 24 hours upon silicone membranes, PDMS tubes, and within 3D PEGDA hydrogels. After stretching

碩士<br>國立交通大學<br>應用化學系<br>90<br>The objectives of our research are to synthesize stable precursors for non-Kekulé tetraradicals, and to study the electronic states of their ground states. After successfully synthesized meta-disultine 32, and para-disultine 36, we have explored their potential application in Diels-Alder reaction and studied their photochemistry and EPR spectroscopy. From these studies, sultines were found to be good precursors for non-Kekulé tetraradicals. When compounds 32 and 36 were reacted with dienophiles in a sealed tube at high temperature, one obtained not

Abstract:

<div>Inorganic metal chalcogenide materials are of great importance in the semiconducting field for various electronic applications such as photovoltaics, thermoelectrics, sensors, and many others. Compared to traditional vacuum processing routes, solution processing provides an alternate cost-effective route to synthesize these inorganic materials through its ease of synthesis and device fabrication, higher material utilization, mild processing conditions, and opportunity for roll-to-roll manufacturing. One such versatile solution chemistry involving a mixture of amine and thiol species has e

Abstract:

Piwi-interacting RNAs (piRNAs) are an animal-specific class of germline-enriched small non-coding RNAs that play a crucial role in germline development and fertility in diverse organisms. In Caenorhabditis elegans (C. elegans), mature piRNAs are uniformly 21 nucleotides (nt) long, and begin with monophosphorylated uridine (therefore, also known as 21U-RNA). They are processed from 25-30 nt long capped RNA precursors, which are transcribed by RNA polymerase II and initiate precisely 2 nt upstream of the 5’-end of mature 21U-RNAs. Therefore, to generate 21 nt long mature piRNAs, the 5’ cap and f

Abstract:

Le pyrrole est un hétérocycle souvent présent dans les produits naturels et les composés biologiquement actifs. Son étude intensive en synthèse organique est donc d'un grand intérêt. Ainsi, la première réaction acido-catalysée de pyrroles sur des nitrones, reportée par notre équipe, a conduit selon les conditions expérimentales employées, soit aux 2,2-bis(pyrrolyl)alcanes symétriques, soit aux N-benzylhydroxylamines pyrroliques de façon sélective. Les N-hydroxylamines pyrroliques sont des composés intéressants et ont été le point de départ des deux études méthodologiques développées dans ce ma

In the new process, diphenyl 4,4''-methylene diphenylcarbamate (DP-MDC), long-chained polyether diamines (eg., Jeffamines) and several different diamine extenders were carried out in the tetramethylene sulfone (TMS; bp 285 ℃) in replacing dimethyl solfoxide (DMSO) as the solvent in the polymerization. In our most desirable polymerization condition, the initial mixing temperature of 90 ℃ for 1 hours was initiate
