Abstract:

L’énantioséparation de précision est essentielle pour les industries pharmaceutiques et alimentaires. Les techniques conventionnelles de séparation chirale offrent un large éventail de méthodes, qui reposent toutes sur des sélecteurs chiraux - des phases stationnaires ou des molécules qui distinguent les énantiomères par une interaction stéréospécifique. Malgré le grand nombre de sélecteurs naturels et synthétiques actuellement utilisés, la demande croissante d’énantiopurité stimule la recherche de nouvelles méthodes polyvalentes.Le but de cette thèse est d'étudier des méthodes alternatives de

Abstract:

Spin dependent electron transport in chiral molecules, the so-called chirality induced spin selectivity (CISS) effect, have attracted much attention over the past few years. Experimentally the spin polarization has been detected, and there is a theoretical consensus on the necessity of both spin-orbit coupling and geometrical helicity in order to get a non-vanishing spin polarization. Several model Hamiltonians has been proposed to describe the CISSS effect, and while they can yield spin polarization agreeing with the experimentally observed magnitudes, they are relying on unrealistic values o

Abstract:

L’objectif de cette thèse est l’optimisation de cellules solaires à base de Cu(In,Ga)Se2 (CIGS) sur substrat métallique à très haut rendement (>20%). Les métaux ont généralement une meilleure tenue mécanique que le verre qui est un matériau fragile. Cela permet par exemple de réduire fortement leur épaisseur et d’obtenir des dispositifs photovoltaïques plus légers. De plus, si leur épaisseur est suffisamment réduite, ils deviennent conformables voire flexibles. Cependant, les substrats métalliques ont leurs propres inconvénients. Ils peuvent contenir des impuretés (ex : Fe) qui dégradent le

Abstract:

Additional out-of-home placement rates for adolescents in long-term regional treatment center (LTRT) programs in the United States are between 50% and 75%. There appears to be a failure to generalize treatment to home and community in programs that do not fully integrate family involvement. The collaborative intensive bridging services (CIBS) treatment model uses intensive family therapy and brief residential treatment center (RTC) placement to reduce or eliminate use of LTRT. Using family systems theory, the purpose of this study was to determine whether participation in CIBS provided better

Abstract:

Many stress situations limit plant growth, resulting in crop production difficulties. Population growth, limited availability and over-utilization of arable land, and intolerant crop species have resulted in tremendous strain being placed on agriculturalists to produce enough to sustain the world's population. An understanding of the principles involved in plant resistance to environmental stress will enable scientists to harness these mechanisms to create stress-tolerant crop species, thus increasing crop production, and enabling the farming of previously unproductive land.

Abstract:

The increasing demand of renewable energy is the big driving force for the research and development of more efficient solar energy conversion solutions. Solar cells, which use the photovoltaic effect to convert the photon energy to electrical current, are an important solar energy conversion technique. One solar cell technology is thin-film solar cells. Thin-film solar cells use an absorption layer with a direct band gap. A direct band gap has the advantage that the photons will penetrate less deep until a photoexcitation occur compared to semiconductors with an indirect band gap (e.g. silicon

The objective of this study was to examine a short conserved sequence within the URE2 element, corresponding to nucleotides 699-719, and to evaluate its contribution to URE2 activity in transgenic mouse forebrain.

碩士<br>長庚大學<br>化工與材料工程學系<br>98<br>Due to the features of saving material, simple process, large-scale fabrication, etc., the thin film solar cell is a potential candidate of low cost solar energy product. Among the thin film solar cell products, amorphous silicon attracts more intention and has been developed. However, there is a barrier for the improvement of efficiency by using this material. In recent years, another thin film material, Copper Indium Gallium Selenide (CIGS), becomes the a interesting material due to its advantages, such as : (a) low fabrication cost, (b) low energy requiremen

Para-methyl red is a photoisomerizable molecule: the transition from low-energy trans to high-energy cis states can be stimulated by irradiation of 365 nm UV light, and the reversed process can be accelerated by irradiation of 450 nm visible light. The structural change can produce a change in the electron cloud distribution, and hence a change in the molecular dipole moment, which can be detected by the field-effect-transistors. I
