Book excerpt: CE MEMOIRE ETABLIT LE PRINCIPE D'UNE NOUVELLE MODELISATION POUR LES ACTIVATIONS DE LIAISONS CARBONE-HYDROGENE BASEE SUR L'EMPLOI DE MICROEMULSIONS INVERSES CATALYTIQUEMENT ACTIVES DANS LESQUELLES LA PHASE CONTINUE EST CONSTITUEE DE L'ALCANE ET D'AEROSOL-OT ET LA PHASE DISPERSEE D'OXYDES DE FER (III) COLLOIDAUX (GENERES IN SITU). L'OXYDANT, LE PEROXYDE D'HYDROGENE OU L'HYDROPEROXYDE DE TERTIOBUTYLE SE REPARTIT DIFFEREMMENT, SELON SA LIPOPHILIE, ENTRE LES DEUX PSEUDOPHASES. LE MODELE A ETE MIS AU POINT AVEC LE CYCLOOCTANE ET LES CONDITIONS AEROBIES OU NON ONT ETE ETUDIEES. L'INFLUENCE D'AUTRES PARAMETRES TELS QUE LA TEMPERATURE, LA NATURE DU METAL A ETE EVALUEE. L'EXTENSION A D'AUTRES SUBSTRATS PERMET DE PRECISER QU'AVEC L'HYDROPEROXYDE DE TERTIOBUTYLE, LA SEQUENCE DE REACTIVITE EST LA SUIVANTE: C-H TERTIAIRE, C-H SECONDAIRE, C-H PRIMAIRE. LES RESULTATS OBTENUS CONDUISENT A POSTULER QUE LA NATURE DE L'OXYDANT INFLUENCE LE MECANISME DE LA REACTION LEQUEL EST ESSENTIELLEMENT RADICALAIRE DANS LE CAS DE L'HYDROPEROXYDE DE TERTIOBUTYLE. POUR REALISER DES ACTIVATIONS C-H PAR DES COLLOIDES POLYOXYHYDROXYLES DU FER (III) COMBINES AVEC L'HYDROPEROXYDE DE TERTIOBUTYLE EN L'ASENCE DE SOLVANT, ON PEUT S'AFFRANCHIR DES MICROEMULSIONS INVERSES THERMODYNAMIQUEMENT STABLES ET TRAVAILLER PLUTOT AVEC DES DISPERSIONS

Download or read book Scientific Basis for Nuclear Waste Management XXII Volume 556 written by David J. Wronkiewicz and published by . This book was released on 1999-11-24 with total page 1370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Safe and effective management of nuclear waste provides a broad range of challenges for materials science. Waste processing, waste form and engineered barrier properties, interactions between engineered and geological systems, radiation effects, chemistry and transport of waste species, and long-term predictions of repository performance are just some of the scientific problems facing modern society. This book, the 22nd in a very successful series from MRS, offers an international and inter-disciplinary perspective on the issues, and features developments in both fundamental and applied areas. Topics include: development and characterization of ceramic waste forms; ceramic waste form corrosion; glass waste form processing; glass formulation, properties and structure; glass waste form corrosion; spent nuclear fuel; performance assessment; repository backfill; flow and transport; natural analogues; container corrosion; metal waste form corrosion; radionuclide speciation and solubility; radionuclide sorption; microbial effects; radiation effects; cement waste forms and waste treatment.
