X-ray absorption spectroscopy of Cu-doped $WO_{3}$ films for use inelectrochemical metallization cell memory
2014
Abstract We have performed the first synchrotron radiation X-ray absorption spectroscopy (EXAFS/XANES) study of the local atomic and electronic structure around Cu and W ions in WO 3 /Cu/WO 3 /Si and WO 3 /Cu/Si multilayered structures, aimed for the application in the electrochemical metallization cell memory. The influence of low-temperature annealing at 135 °C has been investigated in details, and a structural model of Cu-doped WO 3 films is proposed.

Initial approaches in benchmarking and round robin testing for proton exchange membrane water electrolyzers
2019
Abstract As ever-increasing amounts of renewable electricity enter the energy supply mix on a regional, national and international basis, greater emphasis is being placed on energy conversion and storage technologies to deal with the oscillations, excess and lack of electricity. Hydrogen generation via proton exchange membrane water electrolysis (PEMWE) is one technology that offers a pathway to store large amounts of electricity in the form of hydrogen. The challenges to widespread adoption of PEM water electrolyzers lie in their high capital and operating costs which both need to be reduced through R&D. An evaluation of reported PEMWE performance data in the literature reveals that there …

"Jumalan sanan ylenkatsojat" : rahvaan kirkossakäynti Savossa vuosina 1660–1710
2012
1600-luku on perinteisesti tunnettu luterilaisen puhdasoppisuuden aikana, jolloin kirkko ja kruunu kontrolloivat tiukasti Ruotsin valtakunnan alamaisten käyttäytymistä ja ajattelua. Papiston mahdollisuudet ylläpitää kirkkokuria olivat kuitenkin rajalliset harvaan asutuilla syrjäseuduilla, kuten Savon maakunnassa. Artikkelissa käsitellään savolaisen rahvaan kirkossakäyntiä sekä poissaoloja kirkosta 1600-luvun lopulla ja 1700-luvun alussa. Piispan- ja rovastintarkastuspöytäkirjojen avulla selvitetään, miksi poissaolot olivat yleisiä, vaikka kirkossakäynnin laiminlyönnistä seurasi rangaistus. Toisaalta pohditaan sitä, miksi seurakuntalaiset tulivat kirkkoon tärkeinä pyhäpäivinä suurin joukoin …
Nutritional and microbiological quality of tiger nut tubers (Cyperus esculentus), derived plant-based and lactic fermented beverages
2018
International audience; Tiger nut (Cyperus esculentus) is a tuber that can be consumed raw or processed into beverages. Its nutritional composition shows a high content of lipid and dietary fiber, close to those of nuts, and a high content of starch, like in other tubers. Tiger nuts also contain high levels of phosphorus, calcium, and phenolic compounds, which contribute to their antioxidant activity. From those characteristics, tiger nuts and derived beverages are particularly relevant to limit food insecurity in regions where the plant can grow. In Europe and United States, the tiger nut derived beverages are of high interest as alternatives to milk and for gluten-free diets. Fermentation…
Self-reported consumption of wine and other alcoholic beverages in a German wine area
2013
Petra Fronk,1 Maria Blettner,2 Heinz Decker1 1Institute for Molecular Biophysics, Johannes Gutenberg University of Mainz, Mainz, Germany; 2Institute for Medical Biostatistics, Epidemiology and Informatics, Johannes Gutenberg University of Mainz, Mainz, Germany Purpose: To describe the consumption of alcoholic beverages in a German wine area, with special attention to the number of people drinking more than the tolerable upper alcohol intake level (TUAL). Methods: A cross-sectional study was conducted using a mailed questionnaire, to investigate the weekly consumption of wine, beer, and spirits during the preceding 12 months in Mainz, the state capital of Rhineland-Palatinate, Germany. The a…
Monitoring Commercial Starter Culture Development in Presence of Red Grape Pomace Powder to Produce Polyphenol-Enriched Fresh Ovine Cheeses at Indust…
2021
Red grape Nero d’Avola cultivar grape pomace powder (GPP) was applied during fresh ovine cheese production in order to increase polyphenol content. Before cheeses were produced, the bacteria of a freeze-dried commercial starter culture were isolated and tested in vitro against GPP. Two dominant strains, both resistant to GPP, were identified. Thestarter culture was inoculated in pasteurized ewe’s milk and the curd was divided into two bulks, one added with 1% (w/w) GPP and another one GPP-free. GPP did not influence the starter culture development, since lactic acid bacteria (LAB) counts were 109 CFU/g in both cheeses at 30 d. To exclude the interference of indigenous LAB, the pasteurized m…
