Surface-passivating silanization of protozeolitic units has been shown to be an effective strategy for the preparation of ZSM-5 nanocrystals, showing a controlled aggregation degree and a hierarchical porosity. ZSM-5 zeolite materials are thus obtain

Quaternization of poly-(9,9-bis(6’-bromohexyl)fluorenephenylene by treatment with trimethylamine gas was used to obtain a water soluble ammonium salt copolymer. The neutral copolymer containing fluorene/phenylene alternating repeating units was obt

Two-dimensional X-ray diffraction (XRD) analyses of transparent mesoscopically ordered silica/block copolymer composite monoliths reveal single-crystal-like patterns that correspond to well-ordered hexagonal domains that are greater than 1 cm × 1 mm

Aluminosilicate MCM-41 mesophase solids have been prepared under alkaline conditions with high degrees of mesoscopic order and silicon-to-aluminum molar ratios approaching unity. One- and two-dimensional solid-state NMR techniques, in conjunction wit

Biological fuel cells hold promise as an alternative energy source to batteries for unattended ground sensor applications due to the fact that they can be extremely long lived. This lifetime can be extended over batteries by scavenging fuel from the

The chemical compositions and structures of organic-inorganic interfaces in mesostructurally ordered conjugated polymer-titania nanocomposites are shown to have a predominant influence on their photovoltaic properties. Such interfaces can be controll

Multidimensional DECODER NMR experiments are applied to several industrial samples of PET thin films and fibers, exploiting natural-abundance 13 C resonances from different carbon sites to quantify orientational order in these materials. In two-dimen

We have used multiple-quantum NMR to measure the apparent spin network size as a function of excitation time of NaY zeolite samples containing varying amounts of benzene. Behavior observed at low concentrations of benzene was consistent with the pres
