Atomic layer deposition of AlN from AlCl3 using NH3 and Ar/NH3 plasma

2018

The atomic layer deposition (ALD) of AlN from AlCl3 was investigated using a thermal process with NH3 and a plasma-enhanced (PE)ALD process with Ar/NH3 plasma. The growth was limited in the thermal process by the low reactivity of NH3, and impractically long pulses were required to reach saturation. Despite the plasma activation, the growth per cycle in the PEALD process was lower than that in the thermal process (0.4A ° vs 0.7A ° ). However, the plasma process resulted in a lower concentration of impurities in the films compared to the thermal process. Both the thermal and plasma processes yielded crystalline films; however, the degree of crystallinity was higher in the plasma process. The…

Theoretical and computational studies of magnetic anisotropy and exchange coupling in molecular systems

2018

The field of molecular magnetism studies the magnetic properties of molecular systems as opposed to conventional metal-based magnets. The high chemical modifiability of the constituting molecules makes such materials highly versatile, and the small size of the building blocks leads to the rise of various quantum mechanical phenomena, such as tunneling and entanglement. These phenomena can then be further utilized in the construction of nanoscale quantum devices. This dissertation describes computational and theoretical studies in the field of molecular magnetism using state-of-the-art quantum chemical methods based on ab initio multireference approaches and broken symmetry density functional t…

Value Co-Destruction: A Conceptual Review and Future Research Agenda

2023

The service-dominant (S-D) logic lens for understanding value co-creation and customers’ interactive roles in the service exchange has emerged as a focal theme of interest among service academics and practitioners. While recent investigations have also focused on the process of value co-destruction—that is, how potential negative outcomes occur—the concept and its distinction from value co-creation remain unclear. This conceptual review synthesizes the concept of value co-destruction and proposes a framework consisting of two interrelated dimensions—actor–actor interaction and individual actor —and their components at three temporal points of the service encounter. We distinguish value co-…

Pilvisovelluksille sopivia tietokannan hallintajärjestelmiä

2012

Tässä tutkielmassa on tarkoitus selvittää, millaisia vaatimuksia pilvisovelluksilla on tietokannan hallintajärjestelmille ja miten ehdotetut järjestelmät täyttävät nämä vaatimukset. Tutkimus suoritetaan kirjallisuuskatsauksena, joka perustuu tieteellisiin julkaisuihin ja tutkimusartikkeleihin.Aluksi käsitellään pilvimaailman käsitteitä, ominaisuuksia ja haasteita tietokannan hallintajärjestelmille. Viime vuosina on kehitetty lukuisia uusia pilvi-sovelluksille suunnattuja tietokantatuotteita, joista suurin osa kuuluu termin NoSQL alle. NoSQL-tietokantatuotteet eivät perustu relaatioihin, eivätkä käytä pelkästään SQL-kieltä tiedon käsittelemiseen. Nämä ovat pilviympäristössä horisontaalisesti…

Self-healing, luminescent metallogelation driven by synergistic metallophilic and fluorine–fluorine interactions

2020

Square planar platinum(ii) complexes are attractive building blocks for multifunctional soft materials due to their unique optoelectronic properties. However, for soft materials derived from synthetically simple discrete metal complexes, achieving a combination of optical properties, thermoresponsiveness and excellent mechanical properties is a major challenge. Here, we report the rapid self-recovery of luminescent metallogels derived from platinum(ii) complexes of perfluoroalkyl and alkyl derivatives of terpyridine ligands. Using single crystal X-ray diffraction studies, we show that the presence of synergistic platinum-platinum (PtMIDLINE HORIZONTAL ELLIPSISPt) metallopolymerization and f…

“The Chinese Will Not Change; We Have To Change” : Adjustment of the Finns to the Chinese in a Chinese Investment Facilitation Context

2017

This paper explores the intercultural communication, cultural adjustment strategies and power relations between Finnish and Chinese representatives in the context of Chinese investment facilitation in Finland. The study is mostly based on interviews of individuals who work either for one of Finland’s state agencies tasked with attracting investment or local government. When analyzing aspects of power, the paper’s theoretical basis is the Positioning Theory of Harré (1991). Due to the phenomenon of ‘rising China’, the dominant discursive practice of the Finnish positioning is adaption to a communication and working style seen as typically Chinese. The results show the main aspects of Chinese…

Naisjääkiekon lajianalyysi ja harjoittelu

2006

Piia Haakana 2006. Naisjääkiekon lajianalyysi ja harjoittelu. Valmennusopin jatkokurssin seminaarityö, liikuntabiologian laitos, Jyväskylän yliopisto, 34s. Jääkiekon lajianalyysi perustuu pelissä tapahtuviin jatkuvasti muuttuviin tilanteisiin, kuten esimerkiksi kiekonriistoihin, laukauksiin ja kaksinkappailuihin. Lajin ominaispiirteet rakentuvat jään tarjoaman nopeuden päälle, sillä jäällä liikkuminen tekee jääkiekosta erittäin nopean pallopelin jossa tilanteisiin on reagoitava nopeasti. Pelitaktiikka perustuu roolijakoon, josta karkein malli on pelipaikkajako, hyökkääjäpuolustaja- maalivahti, kun taas tarkempi jako määritellään joukkueen pelitaktiikan myötä pelitilanteiden mukaan roolijako…

Understanding teachers’ mental models of collaboration to enhance the learning community

2022

This study examined representations of Finnish basic education teachers’ mental models of collaboration to reveal the background features that enable or hinder changes in a school community and teacher collaboration. In this case study, we explored 41 teachers’ mental models of collaboration in a one-school community to identify and understand the features that enhance or challenge collaboration. The findings raise the question of how collaboration can support a school’s transition to a unified comprehensive school, when teachers are accustomed to working alone with a strong sense of autonomy and diverse mental models of collaboration. The findings revealed that collaboration is mainly limi…
