The Globular Cluster NGC 5286. II. Variable Stars (2009)

Zorotovic, M., Catelan, M., Smith, H. A., Pritzl, B. J., Aguirre, P., Angulo, R. E., ...

We present the results of a search for variable stars in the globular cluster NGC 5286, which has recently been suggested to be associated with the Canis Major dwarf spheroidal galaxy. 57 variable...

The Atacama Cosmology Telescope (ACT): Beam Profiles and First SZ Cluster Maps (2009)

Hincks, A. D., Acquaviva, V., Ade, P., Aguirre, P., Amiri, M., Appel, J. W., ...

The Atacama Cosmology Telescope (ACT) is currently observing the cosmic microwave background with arcminute resolution at 148 GHz, 218 GHz, and 277 GHz. In this paper, we present ACT's first results....

Design and spectroscopic study of new ruthenium(II) complexes containing ligands derived from terpyridine and dipyrido[3,2-a : 2 ',3 '-c]phenazine: {Ru(4 '-Rph-tpy)[dppz(COOH)]Cl}PF6 with R=NO2, Br, Cl (2006)

López, R., Moya, S. A., Zúñiga, C., Yáñez, M., Bayón, J. C., Aguirre, P.

A series of polypyridine ruthenium complexes of the general formula [Ru(Rph-tpy)[dppz(COOH)]Cl) PF6 with R = Br (1), Cl (2), NO2 (3) where Rph-tpy is 4'-(4-Rphenyl-2,2':6',2"-terpyridine and...

Ruthenium carbonyl complexes in catalytic epoxidation of olefins co-catalyzed by isobutyl-aldehyde (2006)

Aguirre, P., Zolezzi, S., Parada, J., Bunel, E., Moya, S. A., Sariego, R.

The present work shows the catalytic activity of a series of carbonyl ruthenium complexes in the epoxidation of olefins co-catalyzed by isobutyl-aldehyde. The complexes display catalytic activity in...

Antioxidant responses of cortex neurons to iron loading (2006)

Aguirre, P., Mena, N., Tapia, V., Rojas, A., Arredondo, Miguel, Núñez, M.T.

Brain cells have a highly active oxidative metabolism, yet they contain only low to moderate superoxide dismutase and catalase activities. Thus, their antioxidant defenses rely mainly on cellular...

REPPE REACTION CATALYZED BY SOLUBLE CARBONYLRHODIUM COMPLEXES (2005)

AGUIRRE, P., UZCÁTEGUI, G. C., HUNG, F., ORTEGA, M. C., PARDEY, A. J., LONGO, C., ...

The catalysis of the hydroesterification and hydroformylation-acetalization of 1-hexene by rhodium(I), cis-[Rh(CO)2(amine)2](PF6) complexes (amine = pyridine, 2-picoline, 3-picoline, 4-picoline,...
