Basic electrochemical characteristics of CaMO3 perovskites (M = Mo, Cr, Mn, Fe, Co, and Ni) as cathode materials for Ca ion batteries are investigated using first principles calculations at the Density Functional Theory level (DFT). Calculations have been performed within the Generalized Gradient ...

Photoluminescence enhancement of Ca3Sr3(VO4)(4):Eu3+,Al3+ red-emitting phosphors by charge compensation In this study, Ca3Sr3(VO4)(4):0.05Eu(3+), Ca3Sr3(VO4)(4):0.05Eu(3+),xAl(3+), and Ca3Sr3(VO4)(4):0.05Eu(3+),0.06Al(3+), yM(+) (M = Li, Na, and K) red-emitti...
cold chemistryradiative associationcharge transferCold chemical reactions between laser-cooled Ca+ ions and Rb atoms were studied in an ion-atom hybrid trap. Reaction rate constants were determined in the range of collision energies E coll/k B=20 mK-20 K. The lowest energies were achieved in ...
The spectral properties of Ce 3+ doped Ca 3Al 2 M 3 O 12 (M =Si,Ge)garnets have been reported under excitation of UV light.The emission spectra of Ce 3+ ion in garnets consist of a broad band assingning to the 5d 4f transition of Ce 3+ ion.The emission intensity Ce 3+ ion ...
Structure and crystal chemistry of the high-T c superconductor YBa2Cu3O7−x Materials within the phase diagram Y2O3–BaO–CuO have recently generated great interest because of the observation of superconductivity with a critical te... WIF David,WTA Harrison,JMF Gunn,... - 《Nature》 被引量...
Such findings provide clear evidence of the main role of charge transfer in determining the Tc of the intercalate. The chemical bonding between host lattice and intercalant layer has also been investigated by performing the Br K-edge and Hg LIII-edge x-ray-abso 展开 ...

Charge ordering phenomena in the manganites Ca_(1 - x)Sm_xMnO_3 have been studied for 0.15 <= x <= 0.60, using electron diffraction and lattice imaging, completed by magnetic and transport measurements. Three domains can be distinguished, depending on the nature of the structural transitions...
They decrease SA charge, and influence the adhesion force between the SA particles and the membrane surface, which turns to accelerate the membrane fouling [30]. The other reason is due to the nature of the Ca ion, which has a special property to the carboxylic group to form an aggregate ...
