A solvothermal self-made composite of graphitic carbon nitride (g-C3N4) and commercially available titanium dioxide (TiO2) demonstrated the removal commercial acid green-25 (AG-25) textile dye in a saline water matrix when activated by ultraviolet (UV) visible light. The g-C3N4-TiO2 was characterized X-ray diffraction (XRD), Nitrogen sorption–desorption recording modeling Brunauer–Emmett–Teller...

To develop more green polymer composites and further know the performance of green composites, the composites based on green poly(L-lactic acid) (PLLA) and starch were fabricated by a counter-rotating mixer. And effect of starch on the fluidity and nucleating performance of PLLA was investigated using melt index instrument, optical depolarizer and wide angle X-ray diffraction instrument, respec...

An improved rapid one-pot and green synthesis of substituted pyranopyranes by condensing Kojic acid, malononitrile, and different aldehydes and using a catalytic amount of cobalt nanoparticles as green and reusable catalyst is reported for the first time. The reaction proceeds in aqueous media at ambient temperature. Furthermore, the structural and morphological study of the cobalt nanoparticle...

Background: The current study tried to investigate the antioxidant and anti-bacterial effects of green tea and grape seed extract (with a volume of 2%) on durability of Tilapia packed inpolyethylene bags, which were kept in cool temperature of 4 ± 1 °C. Methods: Prepared fish were divided into 3 batches: 2 batches were treated by dipping for 30 min in ethanolic of green tea extract (...

5-Aminolevulinic acid accumulated in the culture medium when Agmeneflum quadplicatum strain PR-6 was incubated in the presence of levulinic acid, a competitive inhibitor of 8-aminolevulinic acid dehydratase, and specifically labeled glutamate and glycine. The 8-aminolevulinic acid was purified using Dowex 50W-X8 and cleaved by periodate to yield succinic acid and formaldehyde. The distribution ...

Arabidopsis ubiquitin ligases ATL31 and homologue ATL6 control the carbon/nitrogen nutrient and pathogen responses. A mutant with the loss-of-function of both atl31 and atl6 developed light intensity-dependent pale-green true leaves, whereas the single knockout mutants did not. Plastid ultrastructure and Blue Native-PAGE analyses revealed that pale-green leaves contain abnormal plastid structur...

d-tartaric acid is successfully used as a green and efficient catalyst for the synthesis of 3,4-dihydropyrimidin-2(1h)-ones under solvent-free conditions. the developed method has many advantages, including devoid of harmful catalyst and solvents, high yield and easily work-up.

Volatile organic compounds (VOCs) from uninfested and infested broccoli plant samples with green peach aphid Myzus persicae were investigated by headspace solid microextraction (HS-SPME) combined gas chromatography mass spectrometry (GC-MS). Overall, 25 identified in plants. The HS-SPME GC-MS analysis of the volatiles described differences between samples. Based on peak area analysis, VOCs sign...

1,8-dioxo-decahydroacridines have been synthesized by the three-component reaction of aromatic aldehydes, aromatic amines (or ammonium acetate), and dimedone in the presence of sulfonic acid functionalized nanoporous silica (sba-pr-so3h) under solvent-free conditions. excellent yields, short reaction times, mild reaction conditions, and easy work-up procedures are advantages of this green method.
