Synthesis and Structure Determination of the Hierarchical Meso-Microporous Zeolite ITQ-43
No full textThe formation of mesopores in microporous zeolites is generally performed by postsynthesis acid, basic, and steam treatments. The hierarchical pore systems thus formed allow better adsorption, diffusion, and reactivity of these materials. By combining organic and inorganic structure-directing agents and high-throughput methodologies, we were able to synthesize a zeolite with a hierarchical system of micropores and mesopores, with channel openings delimited by 28 tetrahedral atoms. Its complex crystalline structure was solved with the use of automated diffraction tomography.

A characterization of the Schur property through the disk algebra
No full text[EN] In this paper we give a new characterization of when a Banach space E has the Schur property in terms of the disk algebra. We prove that E has the Schur property if and only if A(D, E) = A(D,E-w). (C) 2016 Elsevier Inc.

ACIDIC PROPERTIES OF TITANIUM-SILICALITES-1
No full textDifferent titanium silicalites-1(TS-1), synthesized following two different routes in the presence or in the absence of sodium in the precursor gel have been characterized by adsorption of ammonia. Adsorption calorimetric measurements of a basic probe(NH3) and an acidic probe(SO2) have shown that these solids were very acidic compared to a silicalite-1 sample. The presence of Na in the different samples decreases the number and the strength of the acid sites. The modification strongly depends on the synthesis procedure
Strongly continuous semigroups on some Fréchet spaces
No full textWe prove that for a strongly continuous semigroup T on the Frechet space omega of all scalar sequences, its generator is a continuous linear operator A is an element of L(omega) and that, for all x is an element of omega and t >= 0, the series exp(tA)(x) = Sigma(infinity)(k=0) t(k)/k! A(k)(x) converges to T-t(x). This solves a problem posed by Conejero. Moreover, we improve recent results of Albanese, Bonet, and Ricker about semigroups on strict projective limits of Banach spaces.
