Simulating a catalyst induced quantum dynamical phase transition of a Heyrovsky reaction with different models for the environment
(IOP Publishing, 2022-03)
Through an appropriate election of the molecular orbital basis, we show analytically that the molecular dissociation occurring in a Heyrovsky reaction can be interpreted as a quantum dynamical phase transition, i.e., an ...
Ultra-fast direct growth of metallic micro- and nano-structures by focused ion beam irradiation
(Nature Publishing Group, 2019-10-01)
An ultra-fast method to directly grow metallic micro- and nano-structures is introduced. It relies on a Focused Ion Beam (FIB) and a condensed layer of suitable precursor material formed on the substrate under cryogenic ...
Mitochondrial Supercomplexes: Physiological Organization and Dysregulation in Age-Related Neurodegenerative Disorders
(Frontiers Media S.A., 2020-09)
Several studies suggest that the assembly of mitochondrial respiratory complexes into structures known as supercomplexes (SCs) may increase the efficiency of the electron transport chain, reducing the rate of production ...
High-energy radiation from collisions of high-velocity clouds and the Galactic disc
(Oxford University Press, 2018-04)
High-velocity clouds (HVCs) are interstellar clouds of atomic hydrogen that do not follow normal Galactic rotation and have velocities of a several hundred kilometres per second. A considerable number of these clouds are ...
Differential stability of aurein 1.2 pores in model membranes of two probiotic strains
(American Chemical Society, 2020-08)
Aurein 1.2 is an antimicrobial peptide from the skin secretion of an Australian frog. In the previous experimental work, we reported a differential action of aurein 1.2 on two probiotic strains Lactobacillus delbrueckii ...
Elucidating the lack of magnetic order in the heavy-fermion CeCu2Mg
(American Physical Society, 2017-03)
Magnetic, transport, and thermal properties of CeCu2Mg are investigated to elucidate the lack of magnetic order in this heavy-fermion compound with a specific heat value, Cmag/T|T→0≈1.2 J/mol K2 and robust effective magnetic ...
Functional morphology and fiber types of the masseter muscles of two caviomorph rodents with contrasting lifestyles, Ctenomys talarum (Ctenomyidae) and Cavia aperea (Caviidae)
(Wiley, 2021-04)
The aim of this work is the analysis of histochemical and morphometric properties of the masseter muscles of Ctenomys talarum and Cavia aperea. The former belongs to a subterranean rodent clade, Ctenomyidae, which has ...
Crime under lockdown: the impact of COVID-19 on citizen security in the city of Buenos Aires
(John Wiley & Sons Inc., 2021-08)
This paper studies the impact of the COVID-19 pandemic and the subsequent lockdown on criminal activity in the City of Buenos Aires, Argentina. Following quarantine restrictions, we find a large, significant, robust, and ...
Fibrous-clay mineral formation and soil evolution in Aridisols of northeastern Patagonia, Argentina
(Elsevier Science, 2007-04)
Recent studies of soil–landscape relationships in northeastern Patagonia identified fibrous-clay minerals in calcic and petrocalcic horizons developed on old fluvio-glacial plains called “Rodados Patagónicos” (RP). The ...
Exosome biogenesis in the protozoa parasite Giardia lamblia: A model of reduced interorganellar crosstalk
(NLM (Medline), 2019-12)
Extracellular vesicles (EVs) facilitate intercellular communication and are considered a promising therapeutic tool for the treatment of infectious diseases. These vesicles involve microvesicles (MVs) and exosomes and ...
