“…Thus, we report in situ control of the exsolved Ni NPs from perovskite to apply as a catalyst for dry reforming of methane (DRM). The La(0.8)Ce(0.1)Ti(0.6)Ni(0.4)O(3) (LCTN) is designed by Ce doping to incorporate high amounts of Ni in the perovskite lattice and also facilitate the exsolution phenomenon. …”

“…The concentration and the ordering of oxygen vacancy in previous work are found to induce ferromagnetic charge‐ordering insulator phase in [(La(0.7)Sr(0.3)MnO(3))(10)/(SrTiO(3))(5)](n) superlattice, which translates into metallic phase with magnetic field H and temperature T . …”

“…The technique is based on the use of a single polycrystalline diamond particle containing silicon-vacancy (SiV) color centers. Due to the presence of amorphous carbon at its intercrystalline boundaries, such a particle is an efficient light absorber and becomes a local heat source when illuminated by a laser. …”

“…We interpret this stabilization imparted by Hf to arise from the suppression of the electrostatic attraction of Sr(2+) cations to surface oxygen vacancies. Doping the surface layer with Hf, that has a higher affinity to oxygen, reduces this attraction by decreasing the surface oxygen vacancy concentration. …”
