Molecular structure and magnetic properties of [Gd(LH4) (NO3)2(H2O)] NO3 (H2O)2, [Sm (LH4) (NO3)2(H2O)] NO3 (H2O)1.5 (CH3OH)0.5 and [Cu2 (LH2) (H2O)2 ](NO3)2 complexes (LH4)] schiff base ligand derived from 4-methyl-2,6 diformylphenol and 1,3-diaminop
(2000)
Novel lanthanide(III) complexes (Ln=Gd (1), Sm (2), La (3)) of the macrocyclic ligand LH4 have been prepared and characterized. The binuclear copper(II) complex (Cu2(LH2)(H2O)2)(NO3)2 (4), has been obtained by transmetalation of ...

Friedolabdanes and other constituents from chilean Haplopappus species
(1991)
From the aerial parts of Haplopappus pulchellus two new labdanes and six friedolabdanes were isolated while H. arbutoides afforded in addition to known labdanes five new ones, two clerodanes and a cyperone derivative. ...
An operando DRIFTS study of the active sites and the active intermediates of the NO-SCR reaction by methane over In,H- and In,Pd,H-zeolite catalysts
(Elsevier Science, 2010-07)
Zeolites In,H-ZSM-5 (Si/Al=29.7, 1.7wt% In) and In,H-mordenite (In,H-M, Si/Al=6.7, 3.5 wt% In) were prepared by reductive solid state ion exchange (RSSIE) method and studied in the selective catalytic reduction of NO ...

Extensões H-cleft distinguidas por H-identidades polinomiais
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Matemática - PPGMCâmpus São Carlos, 2022-05-27)
Our main object of study is the well-known question asking whether the set of polynomials identities distinguishes PI-algebras up to isomorphism. Let k be an algebraically closed field of characteristic 0 and H a non-semisimple ...
