Electrochemistry of methylene blue at an alkanethiol modified electrode

2012

International audience; Gold surfaces were derivatized with decanethiol. The electrochemistry of methylene blue at these modified electrodes was investigated in function of the gold cleaning process and compared with the results obtained at a bare gold electrode. Cyclic voltammetry at low methylene blue concentrations (c(MB) <= 16 mu M) yielded surface behavior data. The properties of the film vary with the electrode pretreatment. Without electrochemical cleaning step, the standard potential at a gold electrode modified with 1-decanethiol is nearly the same as on a bare gold electrode. On the other hand, when the electrode is electrochemically cleaned before adsorption of the alkanethiols, …

On the Relationship between Jetted Inks and Printed Biopatterns:Molecular-Thin Functional Microarrays of Glucose Oxidase

2009

Arrays of circular spots of glucose oxidase have been obtained on functionalized silicon oxide by piezoelectric inkjet printing and the enzymatic activity toward glucose recognition has been monitored. The addition of glycerol to the molecular ink allows to obtain high spot definition and resolution (tens of micrometers wide; one molecule tall), but in spite of its well-known structural stabilizing properties, in dynamic conditions it may lead to increased protein stresses. The jetting voltage and pulse length have been found to be critical factors for both activity retention and pattern definition. High voltages and pulse lengths results in stress effects along with the loss of activity, w…

Effect of pretreatments and drying processo on health-promoting components of goji berries

2020

Drying is one of the most common preservation methods used to extend the shelf life of fruits and vegetables by reducing water content so as to prevent the growth and reproduction of microorganisms and to inactivate many of the moisture-mediated alterative reactions. Goji berries are mainly consumed dried. Several methods can be used to dry goji berries, such as sun drying, hot air drying, vacuum drying, and freeze drying. In this chapter the most used pre-treatment and drying processes found in literature on goji berries are described, together with their effect on their health promoting components, such as carotenoids, tocols, vitamin C, flavonoids and phenols. Moreover the effect of diff…

I presunti dimetri anapestici del dramma attico

2016

Si cerca di mostrare che i Marchanapäste del dramma attico non sono sentiti, almeno da un punto di vista metrico, come dimetri dai poeti.

Commentariolum de origine atque natura dactylo-epitritorum

2021

Si cerca di mostrare che i dattilo-epitriti derivano dalla scomposizione dell´ esametro epico e che non nascono dagli epodi di tipo archilocheo. Si cerca inoltre di mostrare quali sono gli elementi costitutivi dei dattilo-epitriti (hemiepe, trochei, reiziani ecc.) e le combinazioni preferite dai poeti. Vengono analizzati tutti i passi metricamente difficili di Stesicoro, Pindaro, Bacchilide. We try to show that the dactyl-epitrites derive from the decomposition of the epic hexameter and that they do not arise from the Archylokean epodes. It also tries to show what are the constitutive elements of the dactyl-epitrites (hemiepe, trochei, reiziani, etc.) and the combinations preferred by the p…

Sequenze ioniche ed eolo-coriambiche nella tragedia

2016

Viene analizzato per la prima volta in maniera sistematica il problema dell´ ambiguita´ fra sequenze coriambiche e sequenze eoliche nella tragedia (un proble presente soprattutto in Sofocle) e si cerca di interpretare correttamente tutte le sequenze in questione.

In-situ annealing characterization of atomic-layer-deposited Al2O3 in N2, H2 and vacuum atmospheres

2019

Tarkista embargo, kun artikkeli julkaistu. Atomic-layer-deposited Al 2 O 3 films can be used for passivation, protective, and functional purposes in electronic devices. However, as-deposited, amorphous alumina is susceptible to chemical attack and corrosion during manufacturing and field-use. On the contrary, crystalline Al 2 O 3 is resistant against aggressive chemical treatments and corrosion. Here, high-temperature treatments in N 2 , H 2 , and vacuum were used to crystallize alumina which exhibited different crystalline phases. The annealing process was monitored continuously in situ by measuring the film temperature and surface reflectance to understand the crystallization kinetics. Ex…

La cetrería en los ejemplos, símiles y metáforas de san Vicente Ferrer

2012

Vincent Ferrer used in his sermons many and varied resources to make your message intelligible to its many listeners. One such resource was hunting activities and especially the form of hunting with birds. On the one hand, this activity was provided appropriate elements to construct analogies that facilitate the understanding of the word of God. However, on the other hand, it seems that perhaps other reasons may explain this preference of the speaker, more related to their own experience and the reality of the society to which he was going. And, in addition to the textual sources, father Vincent often drew on his own experience and, indeed, to those aspects of the daily lives of his audienc…

Medicina animal en la Baja Edad Media hispánica y su relación con la medicina humana: aves, perros y caballos

2013

The high economic and social value of falcons, hounds and horses in the late Middle Ages led to the development of a specialized medical practice to keep them healthy and treat their diseases. A parallel production of technical works coded this medical knowledge, generating a specific doctrinal body. From the analysis of these treatises it is possible to fi nd close relationships with the current medical doctrine –galenism–, that go beyond the sharing of theories on humors and qualities. The importance of maintaining health and the conceptual instruments to achieve this aim, the precedence of diet as a therapeutic tool over drugs or surgery, treating by applying opposite, techniques of humo…
