Beyond simple AB diblock copolymers: application of bifunctional and trifunctional RAFT agents to PISA in water

Gaëlle Mellot, Patricia Beaunier, Jean-Michel Guigner, Laurent Bouteiller, Jutta Rieger, François Stoffelbach

The influence of the macro-RAFT agent architecture on the morphology of the self-assemblies obtained by aqueous RAFT dispersion polymerization in PISA is studied by comparing amphiphilic AB diblock, (AB)2 triblock and triarm-star shaped (AB)3 copolymers, constituted of N,N-dimethylacrylamide (DMAc…

Glutamic Acid Adsorption and Transformations on Silica

Meryem Bouchoucha, Maguy Jaber, Thomas Onfroy, Jean-François Lambert, Xue Baiyi

We report here on the adsorption and deposition of l-glutamic acid (Glu) on an amorphous silica and its subsequent thermal transformations. When adsorbed from aqueous solutions, Glu only has a low affinity for the silica surface but at high concentrations the adsorbed molecules serve as nuclei for…

Selectivities in Adsorption and Peptidic Condensation in the (Arginine and Glutamic Acid)/Montmorillonite Clay System

Maguy Jaber, Thomas Georgelin, Houssein Bazzi, France Costa-Torro, Jean-François Lambert, Gérard Bolbach, Gilles Clodic

The present study examines the selective adsorption and polymerization of two amino acids, glutamic acid (Glu) and arginine (Arg), on a cationic clay mineral, montmorillonite (Mt). Two experimental procedures were used: selective adsorption and wet impregnation. In the first case, an adsorption…

Pseudo-automorphisms with no invariant foliation

Eric Bedford, Serge Cantat, Kyounghee Kim

We construct an example of a birational transformation of a rational threefold for which the first and second dynamical degrees coincide and are $>1$, but which does not preserve any holomorphic (singular) foliation. In particular, this provides a negative answer to a question of Guedj. On our…

Effects of Pd on Catalysis by Au: CO Adsorption, CO Oxidation, and Cyclohexene Hydrogenation by Supported Au and Pd-Au Catalysts

Anthony Ward, Laurent Delannoy, Ruth Hahn, Shane Kendell, Christopher J. Pursell, Catherine Louis, Bert D. Chandler

catalysts has been shown to have beneficial effects on selective hydrogenation reactions, particularly 1,3- butadiene hydrogenation and the hydrogenation of nitroaromatics, especially p-chloronitrobenzene. Appropriate Pd incorporation enhances hydrogenation activity while maintaining the desirable…

Incorporation of Silver Atoms into the Vacant T-Atom Sites of the Framework of SiBEA Zeolite as Mononuclear Ag(I) Evidenced by XRD, FTIR, NMR, DR UV-vis, XPS, and TPR

Stanislaw Dzwigaj, Yannick Millot, Jean-Marc Krafft, Nataliia Popovych, Pavlo Kyriienko

An AgSiBEA zeolite has been prepared by a two-step postsynthesis procedure that consists of first creating the vacant T atom sites with associated silanol groups by treatment of TEABEA zeolite with nitric acid and then impregnating of resulting SiBEA zeolite with an aqueous solution of AgNO3. The…
