Book excerpt: CE TRAVAIL PRESENTE UNE CONTRIBUTION A LA CONCEPTION ET A LA FABRICATION D'EMPILEMENT MULTICOUCHES A L'ECHELLE NANOMETRIQUE POUR LA REALISATION D'OPTIQUE A RAYONS X MOUS. LES EMPILEMENTS SONT REALISES A L'AIDE D'UN BATI ULTRAVIDE DE PULVERISATION DIODE RF CONCU AU LEP. DES EMPILEMENTS A BASE DE MATERIAUX CLASSIQUES COMME LE TUNGSTENE, LE SILICIUM, LE MOLYBDENE, OU LE CARBONE ONT ETE FABRIQUES. DE TRES BONNES REFLECTIVITES ONT ETE OBTENUES, NOTAMMENT AVEC LES MULTICOUCHES TUNGSTENE/CARBONE ET MOLYBDENE/SILICIUM. PAR DIVERSES METHODES D'ANALYSES (ELLIPSOMETRIE, REFLEXION DE RAYONS X RASANTS, PROFILOMETRIE AUGER, MICROSCOPIE ELECTRONIQUE), NOUS AVONS MIS EN EVIDENCE DIVERSES IMPERFECTIONS STRUCTURALES: RUGOSITE, INTERDIFFUSION, POROSITE. DANS CERTAINS CAS, CES DEFAUTS DE L'EMPILEMENT REDUISENT FORTEMENT LES PERFORMANCES DANS LA GAMME DES RAYONS X MOUS. PLUSIEURS METHODES ONT ETE UTILISEES POUR REDUIRE CES DEFAUTS ET OPTIMISER LA REFLECTIVITE DES MIROIRS. NOUS AVONS MONTRE, DANS LE CAS DES MULTICOUCHES RHODIUM/CARBURE-DE-BORE, ET RHODIUM/CARBONE, COMMENT L'INSERTION D'UN MATERIAU SUPPLEMENTAIRE DANS LA STRUCTURE, POUVAIT LIMITER LA CRISTALLISATION DES COUCHES, LA RUGOSITE ET L'INTERDIFFUSION. UN REFROIDISSEMENT DE L'ECHANTILLON EN COURS DE DEPOT, OU L'UTILISATION D'UNE CIBLE DE GRAPHITE CONDUCTRICE POUR DEPOSER LE CARBONE, ONT PERMIS DE FABRIQUER DES MULTICOUCHES NICKEL/CARBONE DE BONNE QUALITE STRUCTURALE. DES MULTICOUCHES A BASE DE MATERIAUX NOUVEAUX COMME LE SILICIURE DE MAGNESIUM ONT AUSSI ETE FABRIQUEES ET DONNENT DES RESULTATS PROMETTEURS. ENFIN, UN SYSTEME ORIGINAL DE PULVERISATION REACTIVE A PERMIS LA REALISATION DE MULTICOUCHES A BASE DE NITRURES ET D'OXYDES DE TRES BONNE QUALITE. LES RECHERCHES FUTURES PORTERONT SUR CE TYPE DE MATERIAUX (NITRURES, OXYDES, CARBURES), QUI PROMETTENT DES PERFORMANCES ACCRUES, NOTAMMENT AU NIVEAU DE LA STABILITE THERMIQUE

Download or read book Adhesion Between Polymers and Concrete Adh sion Entre Polym res Et B ton written by H. R. Sasse and published by Springer. This book was released on 1986 with total page 792 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preface Adhesion is a phenomenon architects and civil engineers are not very familiar with. In other disciplines knowledge about surface properties and the background of bonding energies is also far from satisfactory; nevertheless there are many important· applications in concrete engineering, where adhesion is necessary for success and durability. These include: - coating and painting - repair of concrete surfaces - bonding of fresh to old concrete - crack injection - glueing of precast elements - glueing of steel to concrete, etc. In 1981 RILEM established the technical committee 52-RAC 'Resin Adherence to Concrete'. The main aims of the committee's work were - to collect research results and practical experiences - to initiate and coordinate research programs - to develop, on a scientific base, test methods for field and for laboratory purposes. One of the results of the committee's work is a state-of-the-art report, which will be presented orally as a General Report at the International Symposium ISAP '86, and will be printed either in the RILEM journal Materials and Structures or separately. Several test recommendations have been elaborated and will be prepared as drafts for the participants ofISAP '86. These are: - direct tensile test - pull-off test - direct shear test - slant shear test - four-point bending test - dynamic loading test - thermal compatibility test (two versions) - injectibility test.

Available in PDF, EPUB and Kindle. Book excerpt: This new, third volume of Cohen-Tannoudji's groundbreaking textbook covers advanced topics of quantum mechanics such as uncorrelated and correlated identical particles, the quantum theory of the electromagnetic field, absorption, emission and scattering of photons by atoms, and quantum entanglement. Written in a didactically unrivalled manner, the textbook explains the fundamental concepts in seven chapters which are elaborated in accompanying complements that provide more detailed discussions, examples and applications. * Completing the success story: the third and final volume of the quantum mechanics textbook written by 1997 Nobel laureate Claude Cohen-Tannoudji and his colleagues Bernard Diu and Franck Laloë * As easily comprehensible as possible: all steps of the physical background and its mathematical representation are spelled out explicitly * Comprehensive: in addition to the fundamentals themselves, the books comes with a wealth of elaborately explained examples and applications Claude Cohen-Tannoudji was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris where he also studied and received his PhD in 1962. In 1973 he became Professor of atomic and molecular physics at the Collège des France. His main research interests were optical pumping, quantum optics and atom-photon interactions. In 1997, Claude Cohen-Tannoudji, together with Steven Chu and William D. Phillips, was awarded the Nobel Prize in Physics for his research on laser cooling and trapping of neutral atoms. Bernard Diu was Professor at the Denis Diderot University (Paris VII). He was engaged in research at the Laboratory of Theoretical Physics and High Energy where his focus was on strong interactions physics and statistical mechanics. Franck Laloë was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris. His first assignment was with the University of Paris VI before he was appointed to the CNRS, the French National Research Center. His research was focused on optical pumping, statistical mechanics of quantum gases, musical acoustics and the foundations of quantum mechanics.

Available in PDF, EPUB and Kindle. Book excerpt: 3D printing is forecast to revolutionise the pharmaceutical sector, changing the face of medicine development, manufacture and use. Potential applications range from pre-clinical drug development and dosage form design through to the fabrication of functionalised implants and regenerative medicine. Within clinical pharmacy practice, printing technologies may finally lead to the concept of personalised medicines becoming a reality. This volume aims to be the definitive resource for anyone thinking of developing or using 3D printing technologies in the pharmaceutical sector, with a strong focus on the translation of printing technologies to a clinical setting. This text brings together leading experts to provide extensive information on an array of 3D printing techniques, reviewing the current printing technologies in the pharmaceutical manufacturing supply chain, in particular, highlighting the state-of-the-art applications in medicine and discussing modern drug product manufacture from a regulatory perspective. This book is a highly valuable resource for a range of demographics, including academic researchers and the pharmaceutical industry, providing a comprehensive inventory detailing the current and future applications of 3D printing in pharmaceuticals. Abdul W. Basit is Professor of Pharmaceutics at the UCL School of Pharmacy, University College London. Abdul’s research sits at the interface between pharmaceutical science and gastroenterology, forging links between basic science and clinical outcomes. He leads a large and multidisciplinary research group, and the goal of his work is to further the understanding of gastrointestinal physiology by fundamental research. So far, this knowledge has been translated into the design of new technologies and improved disease treatments, many of which are currently in late-stage clinical trials. He has published over 350 papers, book chapters and abstracts and delivered more than 250 invited research presentations. Abdul is also a serial entrepreneur and has filed 25 patents and founded 3 pharmaceutical companies (Kuecept, Intract Pharma, FabRx). Abdul is a frequent speaker at international conferences, serves as a consultant to many pharmaceutical companies and is on the advisory boards of scientific journals, healthcare organisations and charitable bodies. He is the European Editor of the International Journal of Pharmaceutics. Abdul was the recipient of the Young Investigator Award in Pharmaceutics and Pharmaceutical Technology from the American Association of Pharmaceutical Scientists (AAPS) and is the only non-North American scientist to receive this award. He was also the recipient of the Academy of Pharmaceutical Sciences (APS) award.
