Preparation and characterization of antifungal colloidal copper nanoparticles and their antifungal activity against Fusarium oxysporum and Phytophthora capsici
In this study, we report the antifungal activity of pure CuNPs against Fusarium oxysporum (F. oxysporum) and Phytophthora capsici (P. capsici). CuNPs were prepared by reducing Cu2+ from copper(II) chloride dihydrate via a green chemical reduction agent using ascorbic acid as both reducing agent and antioxidant agent in aqueous media and polyvinylpyrrolidone as a stabilizer. The effect of the solution pH, reduction time, ascorbic-acid-to-Cu2+ molar ratio, role of stabilizing agent polyvinylpyrrolidone to particle size of CuNPs were studied. The antifungal activity of CuNPs at different concentrations and different particle ...

One-pot microwave-assisted green synthesis of amine-functionalized graphene quantum dots for high visible light photocatalytic application
Publication date: Available online 15 November 2019Source: Comptes Rendus ChimieAuthor(s): Tran Van Tam, T.M. Altahtamouni, Vien Le Minh, Huynh Ky Phuong Ha, Nguyen Thi Kim Chung, Doan Van ThuanAbstractNowadays, graphene quantum dots (GQDs) have gained a huge interest in the field of visible-range photocatalysts because of their tunable band gap and stable photochemical properties. In this work, amine-functionalized GQDs (AGQDs) were successfully prepared by one-step microwave-assisted conversion of glucose, H2O2, and NH3 solution. The obtained quantum dots possess the high quality of graphene structure with the average si...

Extraction of light, medium and heavy rare-earth elements using synergist extractants developed from ionic liquid and conventional extractants
This study focuses on the extraction of rare-earth elements (REE) using eight newly formulated synergist extractants and the performance was compared with that using the conventional extractants. Extraction was conducted on selected REE namely praseodymium (Pr), gadolinium (Gd) and dysprosium (Dy) representing light, medium and heavy REE, respectively. The synergist extractant of A336-[C2mim][NTf2] appeared to be the most positive synergist extractant, especially in the extraction of Pr and Dy based on a 90% increase in the extraction efficiency compared to the conventional extractant of A336. Apparently, the presence of t...

Effect of ion (Ag+, N3−) doping on the photocatalytic activity of the Ruddlesden–Popper-type layered perovskite K2Nd2Ti3O10
Publication date: Available online 15 November 2019Source: Comptes Rendus ChimieAuthor(s): Ramaswamy Kadari, Gundeboina Ravi, Perala Venkataswamy, Radha Velchuri, Nagegownivari Ramachandra Munirathnam, Muga VithalAbstractIn recent years, metal–nonmetal codoping has become a promising approach that can be used for effective tailoring of the structure–activity properties of semiconductors in photocatalysis. In the present study, N-doped K2Nd2Ti3O10 (KNdTON), Ag-doped K2Nd2Ti3O10 (AgNdTO), as well as N and Ag codoped K2Nd2Ti3O10 (AgNdTON) photocatalysts were successfully synthesized by solid-state and ion-exchange methods...

Reactivity of N-methyl-N-(polyfluorobenzyl)acetamides and N-methyl-N-(polyfluorobenzyl)benzamides in Pd-catalyzed C–H bond arylation
Publication date: Available online 8 November 2019Source: Comptes Rendus ChimieAuthor(s): Mohamed Elhadi Benhalouche, Hai-Yun Huang, Abdellah Miloudi, Henri Doucet, Jean-François SouléAbstractThe influence of fluoro substituents on the aryl group of N-methyl-N-benzylacetamides and N-methyl-N-benzylbenzamides on the regioselectivity of palladium-catalyzed direct arylations was studied. With these (poly)fluoro-substituted tertiary benzamides, the arylations proceed very regioselectively at the C–H bond flanked by two fluoro substituents using 2.5 mol% of air-stable palladium catalysts and PivOK/N,N-dimethylacetamide (DM...

Bhuiyan, Md Robiul Hossain, Humayra Bashar, Md Saifur Rahaman, Md Serajum Manir, Ruhul A. Khan, Tomoaki IkegamiAbstractHerein, dye-sensitized solar cells (DSSCs) have been sensitized with natural red dye (extracted from red spinach) and yellow dye (extracted from turmeric) and five different combinations of red and yellow dyes (at different volume ratios) to determine the optimum combination of red and yellow dyes for the maximum cell efficiency. In addition, the effect of post-TiCl4 treatment in improvin...
