Synthesis of cold antihydrogen in a cusp trap.

Abstract: We report here the first successful synthesis of cold antihydrogen atoms employing a cusp trap, which consists of a superconducting anti-Helmholtz coil and a stack of multiple ring electrodes. This success opens a new path to make a stringent test of the CPT symmetry via high precision microwave spectroscopy of ground-state hyperfine transitions of antihydrogen atoms.

Boosting visible-light photocatalytic performance of g-C3N4/Fe3O4 anchored with CoMoO4 nanoparticles: Novel magnetically recoverable photocatalysts

Abstract: In the present work, visible-light-driven g-C3N4/Fe3O4/CoMoO4 photocatalysts (denoted as CN/FeO/CoMoO4) were fabricated by a refluxing-calcination route. The phase, morphology, composition, texture, structure, electronic, textural, thermal, and magnetic properties of the fabricated nanocomposites were studied by XRD, EDX, SEM, TEM, HRTEM, XPS, FT-IR, UV–vis DRS, PL, BET, TGA, and VSM instruments. When the weight percentage of CoMoO4 was 30%, photocatalytic performance of the ternary nanocomposite in degradations of RhB, MB, MO, fuchsine, and photoreduction of Cr(VI) was almost 10, 15, 31.8, 37, and 23.2 times higher than that achieved by the pure g-C3N4. This substantially improved photocatalytic performance was attributed to more production of charge carriers, efficient separation of them from recombination, and enhanced textural properties. Moreover, the photocatalyst was magnetically recovered with negligible loss in the activity, which has key role in design of the sustainable photocatalysts. Therefore, the CN/FeO/CoMoO4 photocatalysts could have potential applications in the environmental remediations.

Hydrothermal preparation of ZnO:CNT and TiO2:CNT composites and their photocatalytic applications

Abstract: ZnO:CNT and TiO2:CNT composites were fabricated under mild hydrothermal conditions (T = 150–240 °C) with an autogenous pressure. The as prepared composites were characterized using X-ray diffraction, Scanning electron microscopy and FTIR spectroscopy. Photocatalytic applications of the composites were investigated using indigo caramine dye. The effect of the catalyst content, pH of the medium, source and intensity of illumination on the photodegradation of the indigo caramine dye was studied and the efficiency of the composites were investigated based on different parameters like percent transmittance (%T), percent decomposition, and chemical oxygen demand of the dye solution to obtain optimum treatment conditions. The results obtained exhibit higher photocatalytic activity when compared to the reagent grade ZnO, TiO2 and hydrothermally prepared ZnO:AC and TiO2:AC composites.
