Chiral discrimination in diasteroisomeric systems of cadmium with 1,10-phenanthroline and S-amino acidates
(1993)
Δ,Λ-[Cd(phen)2(S-aa)]+NO−3 diastereomeric systems (where phen = 1,10-phenanthroline and S-aa = S-alaninate, S-serinate, S-threoninate, S-prolinate, S-valinate, S-leucinate and S-phenylalaninate) have been prepared in the ...
Metallic carbonyl complexes containing heterocyclic nitrogen ligands-I. Rhenium derivatives
(1992)
The preparation and spectroscopic properties of monometallic complexes of rhenium(I)tricarbonylbromide coordinated to 6,7-dihydrodipyrido-[2,3-b : 3′,2′-j]-1,10-phenanthroline (2-4N), 7,8-dihydro-6H-cyclohepta-[2,1-b : ...
Hush theory in a copper mixed valence bioinorganic model generated photochemically
(1993)
In the present study a copper mixed valence (MV) compound has been generated photochemically from the (CH3COO)2Cu(II)Cu(II)(OOCCH3)2 dimeric species in 95/5% (vol./vol.) methanol/acetic acid mixture as solvent. The MV ...
Preparation of new cationic complexes [(η5-C5H5)Fe(dppe)L]PF6 with sulphur and other donor ligands
(1994)
The reaction of (η5-C5H5)Fe(dppe)I with the ligand L′ (L′ = S2(CH3)2, C6H5SNR2 (R = CH3, C6H11), S(NC4H8O)2, P(n-Bu)3, tetrahydrofuran and NC5H5 in the presence of T1PF6 have been investigated. Formation of the new cationic ...
Luminescent hybrid material based on a clay mineral
(2007)
Clay minerals, and within these, the smectite group, including the hectorites in focus, possess layered structures, in which interlayer chemistry may be applied to functionalize them optically. While luminescence from ...

Nuevos pasos para las llantas y los zapatos
(2011)
This reading presents two examples of applied chemistry and the benefits for our environment. Here the useless tires and tennis shoes are recycled to produce raw material to be used in different chemical processes.
Functionalization of polypropylene by grafting with itaconic acid
(Wiley-VCH Verlag, 1996)
Grafting of polypropylene was carried out in both boiling xylene and decalin as solvent medium with itaconic acid (2-methylenesuccinic acid) as functional polar monomer using 2,5-dimethyl-2,5-bis(tert-butylperoxy)hexane ...
Localized spin fluctuations in superconducting alloys
(1974)
The effects due to localized spin fluctuations (LSF) in dilute superconducting alloys are investigated. Expressions for the critical temperature Tc as function of impurity concentration nI and the specific heat jump at the ...
