Charge-transfer driven by ultrafast spin-transition in a CoFe Prussian blue analogue
2020
Photoinduced charge-transfer is an important process in nature and technology and is responsible for the emergence of exotic functionalities, such as magnetic order for cyanide-bridged bimetallic coordination networks. Despite its broad interest and intensive developments in chemistry and material sciences, the atomic-scale description of the initial photoinduced process, which couples intermetallic charge-transfer and spin transition, has been debated for decades; it has been beyond reach due to its extreme speed. Here we study this process in a prototype cyanide-bridged CoFe system by femtosecond X-ray and optical absorption spectroscopies, enabling the disentanglement of ultrafast electr…
Russian speakers’ media engagement and acculturation in Finland and Latvia
2022
AbstractThis comparative study looks into Russian speakers’ acculturation in Finland and Latvia by contrasting their cultural involvement and cultural preference Carlson and Güler (J Int Migr Integr 19:625–647, 2018. 10.1007/s12134-018-0554-4) with their self-reported news media use. Drawing on survey data collected from both countries (N = 224), the findings show that participants in both countries scored closer to biculturalism than monoculturalism. Majority of the respondents report predominantly engaging with non-Russian news media sources. However, regardless of the societal context, respondents who were more engaged with Russian news media sources also scored higher on cultural prefer…
Cīņa par varu Krievijas postimpērijas Rietumu perifērijā (1917–1920): teorētiskās un historiogrāfiskās problēmas
2014
Anotācija Promocijas darbā „Cīņa par varu Krievijas postimpērijas Rietumu perifērijā (1917–1920): teorētiskās un historiogrāfiskās problēmas” ir pētīts, kā mūsdienu vēstures literatūrā ir problematizēta cīņa par varu reģionā starp Baltijas jūru un Melno jūru (Somijas, Igaunijas, Latvijas, Lietuvas, Polijas, Baltkrievijas, Ukrainas teritorijās) periodā no carisma krišanas 1917. gada pavasarī līdz Polijas un Padomju Krievijas pamiera noslēgšanai 1920. gada rudenī. Darbs ir veikts, salīdzinoši analizējot priekšvēsturi cīņai par varu Krievijas postimpērijas Rietumu perifērijā, historiogrāfijā ietvertās cīņu definējošās koncepcijas, kā arī cīņas sekas un nozīmi jeb pēcvēsturi.

Polskie oddziały wojskowe w służbie rosyjskiej w latach 1793-1794. Przyczynki źródłowe
2017
The article discusses, on the basis both of the literaturę on the subject and archival materials preserved in two Russian archives, the fate of military units from the Crown and Lithuanian Army of the Polish-Lithuanian Commonwealth, which in the spring-summer of 1793 were taken to the Russian service. Initially, they had ca. 24 thousand soldiers, but the Russian decided to disband some of the units, while reducing the number of others, thus the number of the servicemen decreased to 15 thousand. The least reduced was the garrison of Kamianets-Podilskyi, for in the service of Empress Catherine II stayed two almost non-reduced infantry regiments of the former Polish Army and part of artillery …
Władysław Stanisław Reymont i Maksym Gorki w perspektywie biograficznej
2016
This paper is an attempt to present the numerous analogies in Władysław Stanisław Reymont‘s and Maxim Gorky‘s outlook on life. It seems that the affinity is partially determined by the coincident biographies of both writers. In literary studies thematic parallels in the writers‘ prose works are frequently mentioned. The paper constitutes a continuation thereof, presenting the problems from a biographical perspective. The paper dedicated to the Polish-Russian literary relations at the turn of the nineteenth and twentieth centuries belongs to the area of comparative studies.
The role of potassium and hydrogen ions in the Prussian Blue ⇆ Everitt's Salt process
1998
Cyclic voltammetry experiments have proved very useful in the knowledge and understanding of the role of the potassium and hydrogen ions during the Prussian Blue ⇄ Everitt's Salt process. While potassium ions act as a stoichiometric reactant, the hydrogen ions play a very important role in the kinetics of the electron-hopping process. The entropy change for the reaction PB ⇄ ES has proved to be dependent on the degree of crystallinity of the film, indicating that this entropy change is related to the fixation of inner counterions on the crystal structure of the films.
The correlation between electrochemical impedance spectra and voltammograms of PB films in aqueous NH4Cl and CsCl
1998
Abstract Voltammetric curves of reduction of Prussian Blue Films to the Everitt’s Salt form and oxidation to the Prussian Yellow form show important differences depending on the supporting electrolyte countercation. The rate of the overall electron-hopping depends on the countercation. Apparent diffusion coefficients are evaluated from impedance spectra at different stabilization potentials. The dependence of the apparent diffusion coefficients on the stabilization potential can help understand the dependence of the voltammograms shape on the countercation nature.
Photoswitchable coordination compounds
2001
Photoswitchable compounds represent an attractive class of materials in coordination chemistry. Recent progress dealing with transition metal compounds involving photo-induced changes of the magnetic and/or optical properties to long-lived metastable states are covered in the present review article. The basic photophysical phenomena together with representative examples such as nitroprusside derivatives, relevant spin crossover complexes, stilbenoid complexes and finally Prussian blue analogues are discussed. Some possible applications regarding energy and information storage are suggested at the end.
