We have developed a visible-light phototransistor with excellent photodetection characteristics and stability via atomic layer deposition (ALD) to add a thin layer of aluminum oxide (Al2O3) to quantum dot (QD)/zinc oxide (ZnO) films.

Β Carotene

Carotenoids were extracted from gametophytes of Allomyces arbuscula at different periods during gametogenesis. After separation by thin-layer chromatography γ-carotene, lycopene and β-carotene were identified from their absorp­tion spectra in visible light. No other carotenoids were detected. After a lag period of 30 min following induction of gametogenesis γ-carotene was the only carotenoid present in extracts, followed by traces of β-carotene at 60 min and by lycopene at 90 min. Accumulation of carotenoids continued during the later stages of gametangia development. Analysis of pigments that had been extracted from asexual mitospores showed that these spores contained both γ-carotene and lycopene.

The One

Tetragonal CuBi2O4/amorphous BiFeO3 (T-CBO/A-BFO) composites are prepared via a one-step solvothermal method at mild conditions. The T-CBO/A-BFO composites show expanded visible light absorption, suppressed charge recombination, and consequently improved photocatalytic activity than T-CBO or A-BFO alone. The T-CBO/A-BFO with an optimal T-CBO to A-BFO ratio of 1:1 demonstrates the lowest photoluminescence signal and highest photocatalytic activity. It shows a removal rate of 78.3% for the photodegradation of methylene orange under visible light irradiation for 1 h. XPS test after the cycle test revealed the reduction of Bi3+ during the photocatalytic reaction. Moreover, the as prepared T-CBO/A-BFO show fundamentally higher photocatalytic activity than their calcinated counterparts. The one-step synthesis is completed within 30 min and does not require post annealing process, which may be easily applied for the fast and cost-effective preparation of photoactive metal oxide heterojunctions.

New Generation

A nanocomposite is a new generation of nanomaterials to improve the tailorable properties of the photocatalytic activity towards the removal of organic and inorganic toxic dyes from the aqueous medium. The hydrothermal technique were used to synthesis the nanocomposite and the particles were examined under the characterization techniques like XRD, UV-Vis, FTIR, FESEM and TEM. The organic and inorganic pollutants can be removed by many of the methods and the best among this is photocatalysis activity. The Methylene Blue (MB), Methylene Violet (MV), Methylene Orange (MO) and Bromophenol Blue (BB) are the two of the dyes which were used in this work. These dyes have excellent photocatalytic Properties to degrade the dyes under the visible light.
