Tunable PL emission of 2D halide perovskites occurs when pressure-induced anisotropic deformation modifies quantum confinement.
Transition metal oxide electrode materials for supercapacitors suffer from poor electrical conductivity and stability, which are the research focus of energy storage field. Herein, multicomponent hybridization Ni-Cu (NCO-Ar/H2 -10) enriched with oxygen vacancy high including Cu0.2 Ni0.8 O, Cu2 O CuO is prepared by introducing Cu element into Ni hydrothermal, annealing, plasma treatment. The NCO-Ar/H2 -10 exhibits specific capacity (1524 F g-1 at 3 A ), good rate performance (72%) outstanding...
3D interconnected MnMoO4 nanosheet arrays with abundant open spaces and ordered arrangements deposited on nickel foam (NF@MnMoO4) are fabricated by a mild one-step hydrothermal method. As an integrated binder-free electrode for supercapacitors, the optimized NF@MnMoO4 exhibits super-high specific capacitance of 4609 F g–1 (640 mAh g–1) at current density 1 A g–1, remarkable rate capability (2800 (388.89 even as high 20 g–1), outstanding cycling stability (92.4% initial after 20,000 cycles)....
Element doping is an effective method to improve the specific capacity and ion transfer rate of binary metal compounds. In this study, Cu-doped Ni–Co-based electrode materials were synthesized by a hydrothermal process subsequent annealing treatment. The experimental results show that nanocone-like Ni–Co carbonate hydroxides (Ni–Co–Cu CH) with high mass loading oxide oxide) abundant oxygen defects achieve area capacities 6.31 F/cm2 6.54 at 3 A/g, respectively, which are about 2.5 times...
A novel method was developed to prepare zinc blende structure CdS:Co diluted magnetic semiconductor nanocrystals. The prepared samples display ferromagnetic behavior with a crystal size of about 3–4 nm. First-principle calculations show the phenomenon ferromagnetism in nanocrystals arising not only from Co atoms, but also Cd vacancies, atoms being major contributor. introduction into CdS significantly reduces formation energy producing lot vacancies which enhance as whole.
To investigate the effect of hydrogen element on diamond crystallization, doped crystals are synthesized at 5.0–6.0 GPa and 1250–1600 °C by adding ferrocene (C10H10Fe) to a system carbon Fe-based solvent–catalyst. The essential dependence morphology nucleation composition crystallization medium is established in P–T diagram. It found that growth region {111} face becomes wider, while {100} narrower almost disappears with increasing concentration C10H10Fe. changing habits can be explained...
Developing a simple and rapidly preparative method for patterned flexible supercapacitors is essential indispensable the swift advancement of portable devices integrated with micro devices.
