A remarkable high entropy effect on the magnetic behaviour of quadruple perovskites

“…The first and the fourth peaks belong to the B.Es of Ti 3+ ions (457.45–458.80 eV: Ti 3+ 2p 3/2 , 463.10–463.50: Ti 3+ 2p 1/2 ), the second and fifth peaks correspond to the B.Es of Ti 4+ ions (458.65–458.70 eV: Ti 4+ 2p 3/2 , 464.55–464.70: Ti 4+ 2p 1/2 ) and finally the third peak is the satellite peak respectively. 69,70 It is also observed that the amount of Ti 4+ ions is more than that of Ti 3+ ions for (La 0.2 Pr 0.2 Nd 0.2 Sm 0.2 Y 0.2 )Cu 3 Ti 2 Mn 2 O 12 and (La 0.2 Pr 0.2 Nd 0.2 Sm 0.2 Y 0.2 )Cu 2.5 Mn 0.5 Ti 1.5 Mn 2.5 O 12 samples. The probability of the presence of the peaks of Ti 3+ ions in (La 0.2 Pr 0.2 Nd 0.2 Sm 0.2 Y 0.2 )Cu 3 Ti 2 Mn 2 O 12 and (La 0.2 Pr 0.2 Nd 0.2 Sm 0.2 Y 0.2 )Cu 2.5 Mn 0.5 Ti 1.5 Mn 2.5 O 12 as compared to (La 0.2 Pr 0.2 Nd 0.2 Bi 0.2 Y 0.2 ) 2/3 Cu 3 Ti 4 O 12 and (La 0.2 Ca 0.2 Ba 0.2 Bi 0.2 Y 0.2 )Cu 3 Ti 3.4 Mn 0.6 O 12 can be due to the presence of impurities.…”

“…S1, ESI†) samples were deconvoluted into 4 peaks. The first and the third peaks correspond to the B.Es of Ti 4+ ions (457.95–458.65 eV: Ti 4+ 2p 3/2 , 463.90–464.60: Ti 4+ 2p 1/2 ) 69 and the second and fourth peaks correspond to satellite peaks. However, the slow scans of Ti 2p spectra for (La 0.2 Pr 0.2 Nd 0.2 Sm 0.2 Y 0.2 )Cu 3 Ti 2 Mn 2 O 12 (Fig.…”

Electrochemical oscillation during galvanostatic charging and discharging of Zr-modified Li4Ti5O12 in Li-ion batteries

“…532 eV increases evidently, corresponding to the functional group of CO 3 2− , additional two Ti 2p peaks appear at ca. 456.4 eV and 461.5 eV, due to the Ti 3+ ions formed after etching, 36 and the Zr 3d peaks is heightened evidently. After etching for 90 s, the atomic percentage of Li element decreases significantly, while the Ti and Zr elements increase evidently, as shown in Fig.…”

SrTiO3@NiFe LDH core–shell composites for photocatalytic CO2 conversion

“…The lattice oxygen in SrTiO 3 was released to the gas phase due to the dissociation of Ti–O bond, usually the surface Ti–O bond, thus forming oxygen vacancies (V O ) and Ti 3+ , as denoted in eqn (1) and (2). 15,41,42 …”
