چکیده
Ion doping in transition metal oxides is always considered to be one of the most effective methods obtain high-performance electrochemical supercapacitors because introduction defective surfaces as well enhancement electrical conductivity. Inspired by smelting process, an ancient method, quenching introduced for ions into with intriguing physicochemical properties. Herein, a proof concept, ?-Fe2O3 nanorods grown on carbon cloths (?-Fe2O3@CC) heated at 400 °C are rapidly put different aqueous solutions alkaline earth salts 4 electrodes doped (M-Fe2O3@CC). Among them, Sr-Fe2O3@CC shows best capacitance, reaching 77.81 mF cm?2 current 0.5 mA cm?2, which 2.5 times that ?-Fe2O3@CC. The results demonstrate feasible new idea improving performances nanostructured materials.

Tuning NaYF4 Nanoparticles through Alkaline Earth Doping
Phase and size of lanthanide-doped nanoparticles are the most important characteristics that dictate optical properties of these nanoparticles and affect their technological applications. Herein, we present a systematic study to examine the effect of alkaline earth doping on the formation of NaYF₄ upconversion nanoparticles. We show that alkaline earth doping has a dual function of tuning parti...
متن کاملHydration of alkaline earth metal dications: effects of metal ion size determined using infrared action spectroscopy.
Infrared laser action spectroscopy is used to characterize divalent Mg, Ca, and Ba ions solvated by discrete numbers of water molecules in the gas phase. The spectra of the hexahydrated ions are very similar and indicate that all six water molecules directly solvate the metal ion. The spectra of the heptahydrated ions indicate the presence of populations of structures that have a water molecule...
متن کاملChemistry of the Alkaline Earth Metal Enolates
Aldehydes, ketones, carboxylic esters, carboxylic amides, imines and N,N-disubstituted hydrazones react as electrophiles at their sp2-hybridized carbon atoms. These compounds also become nucleophiles, if they contain an H atom in the a-position relative to their C O or C N bonds. This is because they can undergo tautomerization to the corresponding enol as seen in Chapter 12. They are also C,H-...
متن کاملQuantum computing with alkaline-Earth-metal atoms.
We present a complete scheme for quantum information processing using the unique features of alkaline-earth-metal atoms. We show how two completely independent lattices can be formed for the 1S0 and 3P0 states, with one used as a storage lattice for qubits encoded on the nuclear spin, and the other as a transport lattice to move qubits and perform gate operations. We discuss how the 3P2 level c...
متن کاملFrom alkaline earth ion aggregates via transition metal coordination polymer networks towards heterometallic single source precursors for oxidic materials.
Heterometallic oxides are used as materials in many applications, e.g. from ferroelectrics to superconductors. Making these compounds usually requires high temperatures and long reaction times. Molecular precursors may contribute to render their processing shorter and accessible at lower temperatures, thus cheaper in energy and time. In this review article, different approaches toward oxide mat...
