Zirconia as a support for catalysts: influence of additives on the thermal stability of the porous texture of monoclinic zirconia [PDF]
, 1991 A single-phase monoclinic zirconia (the thermodynamically stable modification up to a temperature of 1170°C), having a specific surface area of 67 m2g¿1 and a well-developed mesoporous texture, has been prepared by gel-precipitation followed by ...

Oxygen non-stoichiometry and defect structure of LaMn1-zCuzO3+δ [PDF]
, 2015 The quantitative model analysis of the defect structure of copper doped lanthanum manganites LaMn1-zCuzO3+δ (z = 0.05 and 0.1) was performed. In the framework of the model, the independent course of the three reactions of defect formation, including the ...

Measurement of 139La(p,x) cross sections from 35–60 MeV by stacked-target activation [PDF]
, 2019 A stacked-target of natural lanthanum foils (99.9119% 139La) was irradiated using a 60 MeV proton beam at the LBNL 88-Inch Cyclotron. 139La(p,x) cross sections are reported between 35–60 MeV for nine product radionuclides. The primary motivation for this

Incommensurate spin dynamics in underdoped cuprate perovskites [PDF]
, 2005 The incommensurate magnetic response observed in normal-state cuprate perovskites is interpreted based on the projection operator formalism and the t-J model of Cu-O planes.

Interpretation of Nuclear Quadrupole Resonance Spectra in Doped La$_2$CuO$_4$ [PDF]
, 1999 The nuclear quadrupole resonance (NQR) spectrum of strontium doped La$_2$CuO$_4$ surprisingly resembles the NQR spectrum of La$_2$CuO$_4$ doped with excess oxygen, both spectra being dominated by a main peak and one principal satellite peak at similar ...
