Photoinduced Hydrogen Evolution Catalyzed by Co(II) Complexes of N5‐Donor Ligands

open access: yesChemistry – A European Journal, EarlyView.
Cobalt(II) complexes of three related pentadentate ligands have been investigated as photoelectrochemical catalysts for proton reduction/hydrogen gas evolution in the presence of ruthenium, iridium, or copper‐based photosensitizers. Potential mechanisms for hydrogen evolution have been investigated by time‐resolved transient absorption spectroscopy and

Sweet Femininities: Women and the Confectionery Trade in Eighteenth‐Century Barcelona

open access: yesGender &History, Volume 34, Issue 3, Page 574-589, October 2022., 2022
Abstract This article examines the intersections between sweetness, femininity and the confectionery trade in eighteenth‐century Barcelona, at a time of growing consumption of sugar and slavery. Drawing on a range of underexplored archival material, this study traces the stories of women of different social groups, namely, elite housewives, nuns and ...

Molecular dynamics of high‐pressure liquid water: Going from ambient to near‐critical temperatures.

open access: yesChemistry – A European Journal, Accepted Article.
The properties of high‐pressure liquid water were investigated along the isobar of 25 MPa and in the temperature range 298.15‐623.15 K using classical molecular dynamics simulations. Particular attention has been given to the changes in the local structural and related dynamic properties of liquid water.

Catalonia within the Spanish Monarchy: from the Catholic Kings to the War of the Spanish Succession [PDF]

open access: yesЛатиноамериканский исторический альманах
Catalonia maintained broad autonomy for 200 years after the unification of Castile and Aragon at the end of the 15th centu-ry. It was determined both by historical background and by the political situation on the Iberian Peninsula. Ever since joining the

Extended time-delay autosynchronization for the buck converter [PDF]

open access: yesarXiv, 1996
Time-delay autosynchronization (TDAS) can be used to stabilize unstable periodic orbits in dynamical systems. The technique involves continuous feedback of signals delayed by the orbit's period. One variant, ETDAS, uses information further in the past.

Industrial colonies in Catalonia [PDF]

open access: yesCatalan Historical Review, 2011
Industrial colonies, meaning industrial population nuclei located in rural areas, are one of the most characteristic phenomena of the industrialisation process in Catalonia, both because of the industrial, business and social model they developed and because they became one of the most singular features of the landscapes in the Ter and Llobregat river ...

The Careful Combination of Bismuth Compounds and CAAC: Formal Halonium and Nitrenium Transfer via Radical Pathways

open access: yesChemistry – A European Journal, EarlyView.
Fundamental bismuth compounds such as BiCl3 and BiBr(NMe2)2 form simple, colorful adducts with cyclic (alkyl)(amino)carbenes. They undergo facile and selective formal X+ and (NMe2)+ transfer from bismuth to the carbene via peerless radical pathways. Abstract Cyclic (alkyl)(amino)carbenes (CAACs) are key compounds en route to a plethora of unprecedented

Television and electoral results in Catalonia [PDF]

open access: yesSERIEs, 2018
The television channel TV3 has played a controversial role in the Catalan politics since its creation in the early eighties for its alleged partisan bias and support for the Catalan secessionist movement. This paper examines the impact on electoral results stemming from the exposure to TV3 exploiting its staggered expansion across Catalan ...

Practical aspects of multiphase slug frequency: An overview

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Slug frequency, the number of liquid slugs passing through a point per unit of time, is an intrinsic parameter that is used to characterize multiphase slug flows in pipes. In this review we discuss practical aspects of slug frequency for industrial purposes from an examination of published literature and available experimental data. The review
