Spin Crossover and Long-Lived Excited States in a Reduced Molecular Ruby.
2020
Abstract The chromium(III) complex [CrIII(ddpd)2]3+ (molecular ruby; ddpd=N,N′‐dimethyl‐N,N′‐dipyridine‐2‐yl‐pyridine‐2,6‐diamine) is reduced to the genuine chromium(II) complex [CrII(ddpd)2]2+ with d4 electron configuration. This reduced molecular ruby represents one of the very few chromium(II) complexes showing spin crossover (SCO). The reversible SCO is gradual with T 1/2 around room temperature. The low‐spin and high‐spin chromium(II) isomers exhibit distinct spectroscopic and structural properties (UV/Vis/NIR, IR, EPR spectroscopies, single‐crystal XRD). Excitation of [CrII(ddpd)2]2+ with UV light at 20 and 290 K generates electronically excited states with microsecond lifetimes. This…

Impact of supplier-specific investments in inter-organisational information systems on strategic electronic coordination: the moderation effect of bu…
2018
Abstract This paper examines the factors which influence sharing of the strategic information (in other words, electronic coordination) in a buyer–supplier dyad. The antecedents of this coordination are examined rather well in the transaction cost economics (TCE) theory and resource-dependency theory (RDT), while the supply chain management perspective is contemplated. The mentioned frameworks are used in the analysis. However, the research focus is narrowed down to the exploration of the antecedents of information exchange conducted via inter-organisational information systems (IOS). The empirical analysis is based on 198 observations of Norwegian companies operating in different types of …
Viestinnän strateginen rooli organisaatiossa : näkemyksiä viestinnän strategisesta luonteesta ja siihen vaikuttavista tekijöistä
2016
Viestinnän merkitys organisaatiossa korostuu dynaamisessa toimintaympäristössä, sillä viestintäammattilaisen ydinosaamiseen kuuluvat hyvät konfliktin hallintakyvyt sekä sidosryhmätaidot. Silti viestintäammattilaiset joutuvat edelleen paikoittain varjoon organisaation strategisista toimijoista puhuttaessa ja tämä saattaa johtaa esimerkiksi heikompaan budjetointiin sekä vähäisiin vaikuttamismahdollisuuksiin. Tutkimuksen tavoitteena oli lisätä ymmärrystä strategisen viestinnän käsitteestä ja tuoda tuoreita näkökulmia viestintäammattilaisten asemaan organisaatiossa. Tutkimuskysymyksissä pohdittiin viestintäammattilaisen strategista roolia, strategisen viestinnän määritelmää sekä viestintäammatt…
Marine Invertebrates as Bioindicators of Heavy Metal Pollution
2015
The marine environment presents a range of anthropogenic contaminants. According to the World Health Organization, more than 100,000 chemicals are released into the global environment every year as a consequence of their production, use and disposal. The fate of a chemical substance depends on physical-chemical properties, in combination with the characteristics of the environment where it is released. Among the substances that accumulate in the sea, for anthropogenic activities, metals/metalloids have a leading position. Some of these have a biological role but their bioaccumulation is injurious. Chemical pollutants can cause effects on organisms, biodiversity and human health. Various eff…
La rilevazione di stress lavoro-correlato come premessa dell'intervento di ricerca-azione per il miglioramento del benessere organizzativo. Dati e co…
2012
Con riferimento ad una visione dello stress lavoro-correlato come fenomeno che emerge ed acquista senso anche rispetto alla complessiva dinamica psicosociale e culturale dell’organizzazione, e che va collocato all’interno di una irriducibile bipolarità benessere/disagio, una richiesta di rilevazione avanzata da una Azienda Ospedaliera è stata rinegoziata come primo step di un intervento di ricerca-azione orientato al miglioramento del benessere. È stato quindi costruito un questionario atto ad inquadrare i dati più direttamente riferibili allo stress (stato di salute psico-fisica, soddisfazione, senso di appartenenza e di fiducia) all’interno di una cornice ricavata da un altro set di dati …
Analysis of the effects of co-exposure to antibiotics and cadmium on sea urchin embryos
2014
In order to understand the mechanisms of responses to changes in the physical and chemical environment, as well as the mechanisms of developmental pathways, we investigated by RT-qPCR assays and light microscopy observations the impact of antibiotics and cadmium in P. lividus sea urchin embryos. In particular we inspected development and biomarkers for free radical damage and apoptosis. During development embryos were exposed to an antibiotic mix (Ab mix, usually added to sea urchin cultures) or to sulfamethoxazole/trimethoprim mix (TMP/SMX, usually added to aquacultures) and/or levels of 10-5, 10-4, 10-3 M CdCl2. Even though treatment with TMP/SMX apparently did not affect development, it …
Past, present, and future of green product innovation
2021
Firms are under constant pressure from various governmental and nongovernmental agencies to switch from conventional environmentally polluting products to green product innovations (GPIs). However, the relevant research pertaining to GPI has been published in a diverse set of journals that vary in their scope and readership and, therefore, the scholarly contribution to the topic remains largely fragmented. This study has utilised a systematic literature review approach to examine the literary corpus on GPI to paint a holistic picture of its different aspects. The content and thematic analysis of 85 studies resulted in the extraction of seven key research themes: organisational capabilities,…
Compared Binding Properties between Resveratrol and Other Polyphenols to Plasmatic Albumin: Consequences for the Health Protecting Effect of Dietary …
2014
International audience; Phytophenols are considered to have beneficial effects towards human physiology. They are food microcomponents with potent chemopreventive properties towards the most three frequent contemporary human diseases, e.g., cardiovascular alterations, cancer and neurodegenerative pathologies. Related to this, the plasmatic form and plasmatic level of plant polyphenols in the body circulation are crucial for their efficiency. Thus, determinations of the binding process of resveratrol and of common flavonoids produced by major edible plants, berries and fruits to plasma proteins are essential. The interactions between resveratrol and albumin, a major plasma protein, were comp…
