Molecule-like photodynamics of Au102(pMBA)44 nanocluster.
2015
Photophysical properties of a water-soluble cluster Au102(pMBA)44 (pMBA = para-mercaptobenzoic acid) are studied by ultrafast time-resolved mid-IR spectroscopy and density functional theory calculations in order to distinguish between molecular and metallic behavior. In the mid-IR transient absorption studies, visible or near-infrared light is used to electronically excite the sample, and the subsequent relaxation is monitored by studying the transient absorption of a vibrational mode in the ligands. Based on these studies, a complete picture of energy relaxation dynamics is obtained: (1) 0.5-1.5 ps electronic relaxation, (2) 6.8 ps vibrational cooling, (3) intersystem crossing from the low…
Taksā d-h.usāyā. Sakramentalny obrzęd pokuty i pojednania w Asyryjskim Kościele Wschodu
2021
Celem niniejszego artykułu jest zaznajomienie czytelnika z teologią sakramentu pokuty i pojednania w Asyryjskim Kościele Wschodu oraz z wykształconą w łonie tej wspólnoty liturgią jego celebracji zwaną „obrzędem pojednania” (taksā d-h.usāyā). Zaprezentowane badania przeprowadzone zostały w oparciu o syryjską tradycję patrystyczną oraz o najważniejsze źródło liturgiczne, jakim w tym wypadku jest obrzęd, którego redakcję przypisuje się katolikosowi Ishā'Yahbowi III (†659). Analiza obejmuje kolejno teologiczny obraz „odzienia chwały”, który tworzy łączność między sakramentem pokuty a chrztem, sens chrześcijańskiego nawrócenia oraz prezentację obrzędu wraz ze zwróceniem uwagi na jego osobliwośc…

Task-Specific Organic Salts and Ionic Liquids Binary Mixtures: A Combination to Obtain 5-Hydroxymethylfurfural From Carbohydrates
2019
The increase in energy demand and depletion of fossil fuels are among major issues of modern society. Valorization and transformation of raw materials in products of industrial value represents a challenge. This justifies the growing interest of scientific research towards the identification of suitable media and methodologies able to pursue above goals, paying attention to matter of sustainability. On this subject, we studied sulfonic-acid functionalized diimidazolium salts as catalysts for the conversion of fructose and sucrose to 5-hydroxymethylfurfural (5-HMF) in an ionic liquid mixture. In general, using these salts allowed us to obtain 5-HMF in good yields from both substrates in mild…
The Use of Multimodal Resources by Technical Managers and Their Peers in Meetings Using English as the Business Lingua Franca
2020
Background: Engineers increasingly work and advance their careers in international business settings. As technical managers, they need management and technical skills when working with different stakeholders with whom they may not share a common first language. Studies have revealed that informal oral communication skills are of prime importance for global engineers who face challenges in building shared meaning and formulating clear messages in meetings with non-native speakers of English. This article proposes that studying the use of multimodal resources (spoken language, gaze, gestures, and objects) in meetings can unpack how work tasks are accomplished in business through different com…
Universities’ “Third” Mission, Industrial Conversion and the Quest for Surgical Masks: A Sicilian Tale from the First COVID-19 Lockdown
2022
This contribution is a brief testimony of a “third mission” project conducted in collaboration by two university departments that, despite the operational difficulties, and thanks to institutional support, have promoted an initiative aimed at the productive reconversion of a clothing sector company into a health sector company. The project highlights the benefits of integrating different areas of scientific expertise and highlights the role of full involvement and co-creation of a new production unit. Moreover, it is an example of the role that the university can play in a complex operational context in support of a constructive relationship between public and private actors for the develop…

Carbon Nitride-Based Catalysts for High Pressure CO2 Photoreduction
2022
In the current research, the productivity of CO2 photoreduction has been boosted by performing the reaction in an innovative photocatalytic reactor, which allows for operation up to 20 bar. A set of photocatalysts were used, including three types of pristine TiO2, i.e., one commercially prepared (Evonik P25), one home-prepared by flame spray pyrolysis (FSP), and one obtained by the hydrolysis of TiCl4 (TiO2exCl), a bare thermo-exfoliated carbon nitride (C3N4-TE), and binary materials composed of TiO2 and C3N4-TE. The photoreduction was carried out in water at pH 14 and in the presence of Na2SO3 as a hole scavenger. Hydrogen and very small amounts of CO were detected in the head space of the…
Connecting the Language Classroom and the Wild : Re-enactments of Language Use Experiences
2018
AbstractUsing multimodal conversation analysis, this article analyses language learning as an in situ process during a teacher-assigned, experientially based pedagogical activity. The activity involved a three-part pedagogical structure, where learners first prepared for and then participated in real-life service encounters, and later reflected on their experiences back in the classroom. The analysis details how the co-constructed telling sequences through which novice second language users re-enact their experiences create an occasion for language-focused activity. We argue that the actions through which the participants display and sustain an orientation to an interactional practice as an…
