We present a spectroscopic analysis of the early-type massive binary system HD 93403. Using high resolution optical spectra, we clearly separate the primary and secondary components. For the first time, we are able to provide an orbital solution for both stars. Our new orbital parameters show discrepancies with the previous solution published by Thackeray & Emerson (?). We further discuss several spectral features of HD 93403. We finally derive qualitative constraints on the inclination of the system and we discuss its evolutionary status and the position of both components in the Hertzsprung-Russell diagram. Based on observations collected at the European Southern Observatory (La Silla, Chile) and the Cerro Tololo Inter-American Observatory (CTIO). [less ▲]

Recent fieldwork has uncovered three new localities from the Lower Devonian of Mezquita de Loscos (Teruel Province, Spain) with further plant mega-fossils and the first record of micro-fossils. Such plant remains have been interpreted as belonging to a basal euphyllophyte, Taeniocrada-like stems, Hostinella genus and paired sporangia. Fourteen spore taxa were recovered, including Ambitisporites, Aneurospora, Brochotriletes, Chelinospora, Emphanisporites, Gneudnaspora and Retusotriletres, among others. New evidence confirms a Lochkovian age for this outcrop and suggests that the plant diversity was more complex than originally documented. © 2014 © 2014 Taylor & Francis. [less ▲]

New terrestrial and marine palynomorphs of the lower part of the Villavicencio Formation, San Isidro Creek, Precordillera of Mendoza, Argentina, are evaluated. The palynomorph assemblage is dominated by miospores, and also contains acritarchs and scarce chitinozoans. Different processing methods have been tested due to the poor preservation state of the palynomorphs. The new slides provided abundant and diverse palynomorphs and allowed the recognition of 13 miospore species and two acritarch species. This review suggests a late Pragian to early Emsian age, thus confirming and refining previous palynological dating. The miospore assemblage may be correlated with the upper part of the Ems Biozone in terms of the Devonian miospore zonation of the Brazilian Amazon Basin. Palaeogeographically; acritarchs show perigondwanan affinities. In the light of this refined age determination, the stratigraphic and phytogeographic inferences for the Precordillera land plants should be reconsidered. [less ▲]

Due to an increasing need for polymers with well-defined architecture (diblock-, graft-, star-shaped copolymers), molecular weight and/or functional end-groups, the use of controlled radical polymerization (CRP) in scCO2 has started to gain attention. Among all the controlled processes, Atom Transfer Radical Polymerization has emerged as a robust tool for the preparation of polymers with well-defined molecular weight, architecture and chain-end functionality. In a very recent paper, we reported the first efficient dispersion ATRP of methyl methacrylate (MMA) in scCO2 using a fluorinated polymeric ligand that had a dual role, i.e., the complexation of the copper salt and the stabilization of PMMA growing particles. In this contribution, we extended this new system to the dispersion ATRP of styrene2, to the synthesis of diblock copolymers beads2 or to the preparation of PMMA particles by AGET ATRP. Because both ATRP and alkyne-azide Huisgen’s 1,3-dipolar cycloaddition relies on the use of a Cu(I) catalyst, synthesis of pyrene end-functionalized polymers by simultaneous dispersion ATRP and click reaction was also investigated in supercritical carbon dioxide. Finally, the immobilization of these new macroligands onto an inorganic support leads to the formation of pseudo-homogeneous catalyst that were successfully used to prepare CO2-soluble perfluorinated methacrylate and depending on the molecular weight and TEDETA composition of the macroligand, results obtained by supported ATRP without addition of Cu(II) as deactivator are identical to those obtained by homogeneous ATRP.

Periods, or improved determinations of periods, are presented for 29 CP stars observed at La Silla in 1977-1982. The PHOT2 program's algorithm makes possible the bringing together of different observing runs, through an improved reduction of the data to a common standard system. It is noted that, in many instances, magnetic observations would be required for the resolution of ambiguities, especially in the presence of quasi-symmetric double waves. [less ▲]
