A crystalline ZnO/MnOx nanoflower (NF) nanocomposite was deposited on Ni nanocones via an economical synthesis method in which the ZnO NFs were first synthesized, and MnOx was then deposited on the ZnO petals to form a heterostructured composite. The effect of the MnOx coating on the performance of the nanocomposite was analyzed by comparing the performance of supercapacitors employing ZnO and the ZnO/MnOx nanocomposites. The ZnO/MnOx nanocomposites exhibited excellent current rate capability an
A highly transparent, flexible, patternable, and wearable heater by a single-step supersonic kinetic spraying.
A highly transparent self-cleaning superhydrophobic surface was prepared by electrospraying an organosilane-coated alumina precursor.
In this study, we demonstrate rapid and facile supersonic cold spray deposition of Zn2SnO4/SnO2/CNT nanocomposite supercapacitor electrodes with promising combinations of power and energy density. Cyclic voltammetry confirmed the capacitive behavior of the optimized electrode, with specific capacitance reaching 260 F·g–1 at a current density of 10 A·g–1. We attribute this high performance to the optimal combination of CNT (carbon nanotube; double-layer capacitance) and Zn2SnO4/SnO2 (pseudocapaci
