T1 - Certification Report for the Isotopic Reference Materials ERM-AE142 and ERM-EB400 N2 - Lead (Pb) isotope amount ratios are commonly used in applications ranging from archaeology and forensic sciences to terrestrial and extra-terrestrial geochemistry. Despite their utility and frequency of use, only three certified isotope amount ratio reference materials are currently available for Pb: NIST SRMs 981, 982 and 983. Because SRM 981 has a natural Pb isotopic composition, it is mainly used for correcting instrumental mass discrimination or fractionation. This means that, at present, there are no other certified isotope reference materials with natural Pb isotopic composition that could be used for validating or verifying an analytical procedure involving the measurement of Pb isotope amount ratios. To fill this gap, two new reference materials, both certified for their Pb isotopic composition, have been produced together with a complete uncertainty assessment. These new reference materials offer SI traceability and an independent means of validating or verifying analytical procedures used to produce Pb isotope amount ratio measurements. ERM-EB400 is a bronze material containing a nominal Pb mass fraction of 45 mg/kg. ERM-AE142 is a high purity solution of Pb with a nominal mass fraction of 100 mg/kg. Both materials have been specifically produced to assist analysts in verifying or validating their analytical procedures. Note that while one of these reference materials requires the chemical separation of Pb from its matrix (ERM-EB400), the other does not (ERM-AE142). Details on the certification of these isotope reference materials are provided in this report.

T1 - Microwave-assisted synthesis of carbon nanotube-TiO2 nanocomposites in ionic liquid for the photocatalytic degradation of methylene blue N2 - A simple and efficient method of preparing composites of carbon nanotubes and titania (CNT-TiO2) is reported via a microwave-assisted synthesis in an ionic liquid, [bmim][BF4]. CNT-TiO2 nanocomposites were formed by the thermal decomposition of titanium (IV) isopropoxide (Ti(OPri)4) in the presence of CNTs under microwave irradiation. The obtained product was characterized by BET surface area, XRD, SEM, and TEM. TiO2 particles with average size of 9 nm were as anatase. The surface area of the Composites increased with an increase of CNT content. Moreover, the catalytic efficiency of the composite was investigated through the photoelectrodegradation of methylene blue.
