The title indan-1-one derivative, C(18)H(14)O, is planar with an r.m.s. deviation for all 19 non-H atoms of 0.098 Å. The conformation about each of the C=C bonds [1.343 (3) and 1.349 (3) Å] is E. Supra-molecular layers in the bc plane, mediated by C-H⋯O and π-π [ring centroid-centroid distance = 3.5282 (15) Å] inter-actions, feature in the crystal packing.

Carboxymethyl Cellulose/Copper Oxide–Titanium Oxide Based Nanocatalyst Beads for the Reduction of Organic and Inorganic Pollutants

In this work, we have developed novel beads based on carboxymethyl cellulose (CMC) encapsulated copper oxide-titanium oxide (CuO-TiO₂) nanocomposite (CMC/CuO-TiO₂) via Al⁺³ cross-linking agent. The developed CMC/CuO-TiO₂ beads were applied as a promising catalyst for the catalytic reduction of organic and inorganic contaminants; nitrophenols (NP), methyl orange (MO), eosin yellow (EY) and potassium hexacyanoferrate (K₃[Fe(CN)₆]) in the presence of reducing agent (NaBH₄). CMC/CuO-TiO₂ nanocatalyst beads exhibited excellent catalytic activity in the reduction of all selected pollutants (4-NP, 2-NP, 2,6-DNP, MO, EY and K₃[Fe(CN)₆]). Further, the catalytic activity of beads was optimized toward 4-nitrophenol with varying its concentrations and testing different concentrations of NaBH₄. Beads stability, reusability, and loss in catalytic activity were investigated using the recyclability method, in which the CMC/CuO-TiO₂ nanocomposite beads were tested several times for the reduction of 4-NP. As a result, the designed CMC/CuO-TiO₂ nanocomposite beads are strong, stable, and their catalytic activity has been proven.

An entry from the Cambridge Structural Database, the world’s repository for small molecule crystal structures. The entry contains experimental data from a crystal diffraction study. The deposited dataset for this entry is freely available from the CCDC and typically includes 3D coordinates, cell parameters, space group, experimental conditions and quality measures.

Simple approach for the synthesis of zinc oxide nanorods

For the first time, a simple and novel approach has been described for the preparation of zinc oxide nanorods by a simple reaction of zinc metal with water in the temperature range of 50°C-200°C. The diameters of the nanorods are in the range 30 nm to 100 nm with several micrometers in length. The influence of the reaction temperature on the morphologies has been discussed in detail. A plausible mechanism is proposed for the formation of these nanorods and is expected that this synthetic technique can be extended to obtain other metal oxides. The reported method is new, cheap, fast, environmentally benign and free of pollution, which will make it suitable for large scale production.

Electrodeposition and Characterization of Polyaniline on Stainless Steel Surface via Cyclic, Convolutive Voltammetry and SEM in Aqueous Acidic Solutions

The electrodeposition of polyaniline on stainless steel electrode was carried out in aqueous media at two different concentrations of sulphuric acid under potentiodynamic conditions. It was found that the nature of the voltammograms in 0.5M and 1M of H2SO4 are simillar. The first voltammetric wave (A1 &#x0026; C1) of the cyclic voltammograms corresponding to transition from leucoemaraldine (LE) state to emeraldine (EM) state. The deposited films were characterized electrochemically and microscopically. The deposition of polyaniline appears to occur over the passive metal oxide film and the electron transfer between the polymer and the metal occur. Polyaniline films on stainless steel appear to be promising for metal anodic protection in corrosive aqueous media. The electrochemical parameters of the electrodeposited polyaniline were determined using cyclic voltammetry, convolution- deconvolution transforms and derived chronoamperograms.

<i>N</i>-(2-Bromophenyl)-4-methyl-<i>N</i>-(4-methylphenylsulfonyl)benzenesulfonamide

In the title compound, C(20)H(18)BrNO(4)S(2), the mean planes formed by the toluene substituents are inclined at a dihedral angle of 45.34 (8)°. The bromo-benzene group is disordered over two positions with an occupancy ratio of 0.74:0.26, resulting in two conformations of the ring; the two rings are oriented at a dihedral angle of 6.6 (6)° with each other. In the crystal structure, weak C-H⋯O inter-actions connect the mol-ecules in a zigzag manner along the a axis.

Development of an efficient electrochemical sensing platform based on ter-poly(luminol-<i>o</i>-anisidine-<i>o</i>-toluidine)/ZnO/GNPs nanocomposites for the detection of antimony (Sb³⁺) ions

A poly(luminol-<i>o</i>-anisidine-<i>o</i>-toluidine) terpolymer was synthesized, characterized, and modified with GNPs and ZnO NPs. The nanocomposites were then examined for their electroactivity and potential use as cationic electrochemical sensors for detecting Sb³⁺ ions in phosphate buffer on the surface of a glassy carbon electrode (GCE). Among the different compositions and the terpolymer, the GCE adapted with the PLAT/ZnO/GNPs-5% nanocomposite displayed the highest current response. The fabricated nanocomposite sensor exhibited high sensitivity, with a value of 21.4177 μA μM^-1 cm^-2, and a low detection limit of 95.42 pM. The analytical performance of the sensor was evaluated over the linear dynamic range (LDR) of 0.1 nM to 0.01 mM. The proposed sensor is effective in detecting and measuring carcinogenic Sb³⁺ ions in real environmental samples using an electrochemical approach, making it a promising tool for environmental monitoring.
