Bruce, Henrik. "Formulation of Model Problem for Chirality Induced Spin Selectivity Effect." Thesis, Uppsala universitet, Materialteori, 2020. http://urn.kb.se/resolve?urn=urn:nbn:se:uu:diva-414026.

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’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:

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.

It is essential to make performance measurements of photovoltaics modules in order to quantify the power they will produce under operational conditions. Performance measurements are fundamental throughout the photovoltaic industry, from product development to quality control in manufacturing and installation in the field.

However some devices have characteristics which can cause difficulties making these measurements. The aim of this thesis is to overcome these measuremen

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 purpose of the study presented in this thesis is to investigate the influence of aryl substitution on the N(2)-N(3) rotational barrier of meta and/or para substituted cis-1,3-diphenyltriazenes.

Abstract:

L'objectif de ce travail de thèse a été en premier lieu de concevoir et de synthétiser quatre polymères photosensibles utilisables industriellement comme films d'alignement des cristaux liquides. Dans un deuxième temps, des études par spectroscopie UV et IR ont permis de caractériser l'anisotropie et l'évolution de la composition de ces matériaux en cours d'irradiation en lumière linéairement polarisée. Dans le cas général, il a ainsi été possible de mettre en évidence la compétition de deux photo réactions : la cycloaddition 2+2 et l'isomérisation trans/cis. Ainsi, trois espèces cohabitent au

Due to the advantages of high photoelectric efficiency and low materials cost, it is worth to keep studying these two material systems. In this experiment, three kinds of different precursors were used to synthesize CIS and CIGS powder. XRD, SEM, EDS, and TEM were then used to analyze crystallization, composition, particle size, and morphology of powder products. The composition of th

CIGS is one of the best candidate materials for thin film solar cell due to its strong light absorption as well as its relatively high mobility. It also has the advantage to reduce production cost for photovoltaics devices, and nowadays, the fabrication of CIGS solar cell is mature and commercial. But some problems like uniformity, morphology, and yield still affect the quality of CIGS solar cell and reduce its market in the competition with other

Abstract:

Triazenes, compounds containing a diazoamino moiety (–N(1)=N(2)–N(3)<), are known for their reversible cis-trans isomerization character and hence, have the potential to be used in photoswitchable devices and photostorage media. However, little is known about their cis-trans isomerization mechanism. In this thesis, kinetic studies on the thermal cis-to-trans isomerization of N-(phenylazo)-substituted nitrogen heterocycles are presented. It is shown that the isomerization rate constant increases as the size and electron-donating character of the cyclic amine increases, as the electron-withdrawi

First, the photoluminescence of defect-related Cu(In,Ga)Se2 thin film solar cells show the donor-acceptor transition and band-impurity transition. The donor level and acceptor level can be extracted. The negative temperature coefficient of the short circuit current of Cu(In,Ga)Se2 solar cells may cause more degradation of power conversion efficiency at high temperature du

Adipic acid is an important raw material for producing plastics such as nylon 6,6 which is produced through chemical synthesis; however, that chemical manufacturing will cause a lot of greenhouse gases of NOx to be discharged during the process thus adding to the greenhouse effect. Energy consumption and environmental pollution can be reduced if white biotechnology is used to replace the chemical synthesis to produce the MA. Our laboratory
