A new cosmetic ASPION CE was commercialized by utilizing a novel surfactant coating technique for L–ascorbicacid phosphate magnesium salt (Vitamin C).The coating technique can change the surface properties of cosmeticingredients. In developing the ASPION CE, the hydrophilic property of ascorbic acid derivative was con…
北千葉導水路の稼働に伴い手賀沼における藻類の優占種は、藍藻類のMicrocystis aeruginosa（M. aeruginosa）から珪藻類のCyclotella sp.へと変化している。本研究は、導水がもたらした高濃度のケイ素条件（11 mg－Si･l－1）におけるリン濃度の変動がM. aeruginosaとCyclotella sp.の優占化に及ぼす影響について、リンの濃度を0.02、0.1および0.5 mg－P・l－1に変化させた単種培養実験およびリンの濃度を0.1 mg－P・l－1としたときの競合培養実験を通じて検討した。単種培養実験を行った結果、M. aeruginosaおよびCyclotella sp.のリンに対…
An entry from the Cambridge Structural Database, the world’s repository for small molecule crystal structures. The entry contains experimental data from a crystal diffraction study. The deposited dataset for this entry is freely available from the CCDC and typically includes 3D coordinates, cell parameters, space grou…
In the present review, we will summarize recent studies on photochemistry of supramolecules using imides. Recently, imides have been employed in various functional molecular systems including biomolecules, solar cells, and molecular devices, because of its excellent photophysical and electron accepting properties. Our…
Phenol is one of the most important chemicals in industry and it is produced from cumene process from benzene. Direct phenol synthesis from benzene and O2 is an alternative way to produce phenol efficiently. We have succeeded in preparing a HZSM-5-zeolite-supported Re catalyst, which was highly active and selective fo…
Cette thèse présente des travaux récents relatifs à la modélisation d'impact de projectiles mous et le développement d'une méthode numérique sans maillage. En premier lieu, la théorie rattachée aux impacts d'oiseaux ainsi que les méthodes numériques et résultats expérimentaux disponibles sont donnés afin d'établir des…
Dans ce travail, des résines époxydes et des fibres naturelles ont été utilisées afin de produire des matériaux composites. En particulier, l'étude a porté sur la fabrication et la caractérisation de plusieurs types de résines époxydes et aussi sur plusieurs types de fibres naturelles en utilisant des amines comme age…
La signature du Protocole de Kyoto par le Canada en décembre 2002 et les nouvelles normes environnementales qui en découleront nous forcent déjà à trouver des solutions pour réduire de façon significative les émissions de gaz à effet de serre, et en particulier le CO₂. Une des façons de réduire de telles émissions con…
Esta memoria de tesis se basa en es el estudio de la relacion entre la estructura y las propiedades de una nueva familia de materiales bimodales de base olefinica obtenidos mediante catalisis dual, lo que exige el uso de distintas tecnicas de caracterizacion. En concreto se abordara el estudio de materiales poliolefin…

Heterogeneous catalysis using supported gold nanocrystallites has attracted increasing attention over the last two decades for its applicability to a wide range of reactions, offering activity under ambient conditions, as well as high selectivities towards particular products. This study focuses on a relatively uncomm…
Neste trabalho estudou-se a relação entre o comportamento mecânico e a microestrutura da liga de alumínio 6082, sujeita a diferentes condições de tratamento térmico de envelhecimento. Os perfis de liga estudada resultam de um processo de extrusão industrial da empresa Extrusal. Este trabalho pode ser dividido em duas…
This thesis is a part of a larger project involving the Faste Laboratory at Luleå University of Technology and the Wingquist Laboratory at Chalmers University of Technology. The interaction between simulation driven design and variation simulations is the main focus of this project. Computational welding mechanics has…
Este trabalho descreve a preparação de argilas organofílicas a partir de uma argila nacional. Portugal possui um vasto parque natural de argilas e, no contexto actual de afirmação das empresas nacionais, é importante diversificar as suas aplicações. Ora uma maneira interessante de o fazer pode ser através da utilizaçã…
Single molecule imaging has emerged as a powerful tool in a range of applications, but the field is limited by a lack of fluorescent probes with sufficient brightness and photostability for many demanding applications such as tracking of single biomolecules in cells and tissues at video rate with 1 nm spatial resoluti…
Liquids under the influence of external \nfields exhibit a wide range of intriguing phenomena that can be markedly different from the behaviour of a quiescent system. This work considers two different systems — a glassforming Yukawa system and a colloid-polymer mixture — by Molecular Dynamics (MD) computer simulations…
Conventional wood plastic composites (WPCs) in general combine wood residuals with thermoplastics such as polyethylene and polypropylene. The basic idea in this work is to replace these olefin plastic matrixes in WPCs with a so-called biobased plastic, namely poly(lactic acid) (PLA). To reduce the water sensitivity of…
An experimental investigation was conducted to analyze the effects of biodiesel-ethanol and biodiesel-diesel blended fuels on the characteristics of combustion and exhaust emissions, and size distributions of particulate matter in a single cylinder diesel engine. The three types of test fuel were biodiesel and two ble…
Cette étude présente des résultats zootechniques et économiques en lien avec une augmentation du poids d'abattage des porcs au Québec. Un essai zootechnique permet d'obtenir une appréciation de l'effet du poids d'ahattage sur les performances les plus susceptibles d'affecter la rentabilité d'une entreprise porcine. Da…
