“…22 In comparison with these recent results, Co 3 O 4 /Zn-Co-Mo/NF described in this paper delivers excellent performance due to the good conductivity and viscosity of NF, high porosity, large specific surface area, and more active substances. [23][24][25][26] Hydrogen evolution reaction.-A three-electrode system with the platinum electrode as the counter electrode and saturated calomel electrode as the reference electrode is adopted to evaluate the catalytic properties of Co 3 O 4 /Zn-Co-Mo/NF in HER under alkaline conditions. Figure 8a shows that the activity of Co 3 O 4 /Zn-Co-Mo/NF is higher than that of NF, Co 3 O 4 /NF, Zn-Co-Mo/NF.…”

Mixed transition metal compounds with abundantly more active sites are attractive to supercapacitors and electrochemical water splitting. In this work, the Co3O4/Zn-Co-Mo/NF composite is prepared by a hydrothermal method and thermal annealing. The Zn-Co-Mo nanosheet arrays are synthesized on nickel foam (NF) to form a three-dimensional (3D) network to take advantage of the electrical conductivity and viscosity of NF. Co3O4 is produced directly in the 3D microchannels to achieve a large energy density and robust stability. In a test of the supercapacitor performance, the specific capacitance of Co3O4/Zn-Co-Mo/NF is 2169 F/g at a current density of 1 A/g. In addition, excellent long-term cycling stability is observed as manifested by specific capacitance retention of 85% after 4,000 cycles at a current density of 25 A/g. As a catalyst in the hydrogen evolution reaction (HER), Co3O4/Zn-Co-Mo/NF shows an overpotential of 128 mV at 10 mA/cm2. Our results confirm the dual functionality of the materials which have promising potential in energy storage and generation applications.

“…Various Mn oxides in nanoscale form (α-MnO 2 , Mn 3 O 4 , Mn 5 O 8 , Na 2 Mn 5 O 10 , and Na 4 Mn 9 O 18 ) were synthesized for 40 min at 140 °C using hydrothermal heating by microwaves followed by heat treatment (160, 480, 715, 870, 920, and 1150 °C) . Copper (Cu) oxide/Mn dioxide (CuO/MnO 2 ) NCs were obtained by a simple method of synthesis using microwave radiation in a conventional household microwave oven and used for an electrochemical supercapacitor …”

Manganese (Mn) is an important microelement for the mineral nutrition of plants, but it is not effectively absorbed from the soil and mineral salts added thereto and can also be toxic in high concentrations. Mn nanoparticles (NPs) are less toxic, more effective, and economical than Mn salts due to their nanosize. This article critically reviews the current publications on Mn NPs, focusing on their effects on plant health, growth, and stress tolerance, and explaining possible mechanisms of their effects. This review also provides basic information and examples of chemical, physical, and ecological (“green”) methods for the synthesis of Mn NPs. It has been shown that the protective effect of Mn NPs is associated with their antioxidant activity, activation of systemic acquired resistance (SAR), and pronounced antimicrobial activity against phytopathogens. In conclusion, Mn NPs are promising agents for agriculture, but their effects on gene expression and plant microbiome require further research.
