A new method for elaborating mesoporous SiO 2 /montmorillonite composite materials

Khalil Tesnime Abou, Chaabene Semy Ben, Boujday Souhir, Blanchard Juliette, Bergaoui Latifa

We report the sol–gel preparation of SiO 2 / montmorillonite composite materials and the investigation of the effect of the amount of clay and the TEOS concentration on the textural and structural properties of the composites. Pre-swelling of the clay with cetyltrimethyl ammonium results in solids…

Nanocrystalline NbC formation from mesostructured niobium oxide studied by HRTEM, SAED and in situ XRD

S. Witkowski, M. Ruszak, Celine Sayag, J. Pielaszek, G. Djéga-Mariadassou

Mechanism of the nanometric size niobium carbide synthesis from mesostructured niobium oxide precursor is proposed. High-resolution transmission electron microscopy (HRTEM) and selected area electron diffraction (SAED) combined with in situ X-ray diffraction (XRD) were successfully used to study…

The influence of the preparation procedures on the catalytic activity of Fe-BEA zeolites in SCR of NO with ammonia and N2O decomposition

Paweł Boroń, Lucjan Chmielarz, Jacek Gurgul, Kazimierz Łątka, Barbara Gil, Jean-Marc Krafft, Stanislaw Dzwigaj

Three series of Fe-containing BEA zeolites are prepared by two-step postsynthesis (PS), ion exchange (IE) and conventional wet impregnation (Imp) procedures with various Fe content (1.0–4.0 Fe wt.%). In these series of zeolites iron is mainly present as pseudo-tetrahedral Fe(III) as evidenced by…

HgTe Nanocrystal Inks for Extended Short‐Wave Infrared Detection

Bertille Martinez, Julien Ramade, Clément Livache, Nicolas Goubet, Audrey Chu, Charlie Gréboval, Junling Qu, William L Watkins, Loic Becerra, Erwan Dandeu, Jean Louis Fave, Christophe Méthivier, Emmanuelle Lacaze, Emmanuel Lhuillier

Short‐wave infrared (IR) detection is currently driven by InGaAs technology which has limited the perspective of cost effectiveness and consequently slows the development of IR sensors. Since organic electronics are ineffective in this wavelength range, an alternative to conductive polymers is the…

Mueller micropolarimeter for color imaging of aluminium metasurfaces

M. Nicolas, I. Soumahoro, L. Zhang, G. Guida, W. Daney de Marcillac, D. Demaille, C. Schwob, S. Boujday, Bruno Gallas

Many anticounterfeiting tags rely on images intricate in different color and/or different polarization states to create optical effects invisible in conventional observation conditions. We build here an imaging micropolarimeter based on the dual rotating compensator system and using the color…
