Transition metal oxide-based electrode materials for flexible supercapacitors: A review

The fabrication of fungicides in cost-effective and eco-friendly ways is particularly important for agriculture. Plant pathogenic fungi produce many economic and ecological problems worldwide, which must be controlled with potent fungicides. Here we propose the green synthesis of fungicides, which consist of copper nanoparticles (Cu-NPs) prepared in aqueous media. Through in vitro experiments, the antifungal efficacy against Fusarium solani, Neofusicoccum sp., and Fusarium oxysporum was investigated. Although the antifungal activity differs for each fungal species, it was found that the Cu-NPs induce strong morphological changes in the mycelium. Additionally, the damage of the cell membranes of the pathogens was revealed by microscopic observations. For the three evaluated fungi, fluorescence microscopy demonstrated the intracellular generation of reactive oxygen species in the mycelium. This work proves that the green-synthesized Cu-NPs are potential fungicides against F. solani, Neofusicoccum sp., and F. oxysporum.

Aqueous-phase synthesis of nanoparticles of copper/copper oxides and their antifungal effect against Fusarium oxysporum.

A theoretical study about the interaction between small gas molecules (H2O, CO, CO2, NH3, and CH4) with graphene quantum dots (GQDs) was performed. To develop gas sensors with ultralow detection levels, the nature of the bonds between the gas molecules and the GQDs should be understood and controlled. It was found that the binding energy (Eb) of the gas molecules with the GQDs can be controlled if the GQDs are doped. In the first part of the investigation, a choice of appropriated exchange/correlation functionals and basis sets was achieved. After this, the pure generalized gradient approximation (GGA) functionals, including the non-local (NL) density-dependent dispersion correction and the atom-pairwise dispersion correction (D3), were employed and found that they described accurately the Eb for the adsorption of water on GQDs. The use of NL and D3 corrected GGA functionals revealed that the Eb for the adsorption of H2O, CO, and NH3 on Si- and Al-doped GQDs can be improved, which indicates that the detection limit for the detection of these gases can be enhanced. To understand the nature of the bonds involved in the adsorption, different approaches were used, such as the quantum theory of atom in molecules and the electron localization function.
