Here, we have demonstrated for the first time the synthesis of a novel LaNiSbWO4-G modified by polyaniline (PANI) via a sonochemical process. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images show well-crystallized small nanoparticles in the photocatalysts. FTIR, DRS, Raman, and XPS were also used for analyses. LaNiSbWO4-G-PANI showed efficient photocatalytic activity

A novel chromogenic and fluorometric sensor based on [5]helicene-like-dye-bearing rhodamine 6 G thiohydrazide, i.e. NF09, was successfully designed and synthesized for the detection of Hg2+. NF09 exhibited ultrasensitive and highly selective recognition of Hg2+ on the basis of the fluorescence resonance energy transfer process from the [5]helicene-like donor to the rhodamine 6 G acceptor. The photophysical

The synthesis of mesoporous TiO2 nanosheets is reported using Ti(IV) Isopropoxide as Ti(IV) precursor. A sol-gel process combined with microwave activation is used. Three different halogenhydric acids (HX), were used to peptise the sol: HF(ac), HCl (ac) and HBr (ac). The three obtained TiO2-I(HX) samples were characterized by XRD, XRF, N2-adorption, SEM, TEM, DRS and XPS. The three synthesized samples
