Tellurium(II)-Centered Dications from the Pseudohalide “Te(OTf)2”
2009
Te for two: Supported by pyridine- or carbene-based ligands, tellurium-centered dications are prepared in high yield and include a dicationic tellurium analogue of the recently synthesized “carbodicarbene”. The key to accessing these compounds is the isolation of a base-stabilized form of TeOTf2 (see structure), a new highly electrophilic reagent for tellurium chemistry. peerReviewed
Measurement of the energy distribution of electrons escaping minimum-B ECR plasmas
2017
The measurement of the electron energy distribution (EED) of electrons escaping axially from a minimum-B electron cyclotron resonance ion source (ECRIS) is reported. The experimental data were recorded with a room-temperature 14 GHz ECRIS at the JYFL accelerator laboratory. The electrons escaping through the extraction mirror of the ion source were detected with a secondary electron amplifier placed downstream from a dipole magnet serving as an electron spectrometer with 500 eV resolution. It was discovered that the EED in the range of 5–250 keV is strongly non-Maxwellian and exhibits several local maxima below 20 keV energy. It was observed that the most influential ion source operating pa…
Diagnostics of highly charged plasmas with multicomponent 1+ ion injection
2022
We establish multicomponent 1+ injection into a charge breeder electron cyclotron resonance ion source and an associated computational procedure as a noninvasive probe of the electron density ne, average electron energy ⟨Ee⟩, and the characteristic times of ionization, charge exchange, and ion confinement of stochastically heated, highly charged plasma. Multicomponent injection allows refining the ne, ⟨Ee⟩ ranges, reducing experimental uncertainty. Na/K injection is presented as a demonstration. The ⟨Ee⟩ and ne of a hydrogen discharge are found to be 600+600−300eV and 8+8−3×1011cm−3, respectively. The ionization, charge exchange, and confinement times of high charge state alkali ions are on…
Nowa polityka. Wprowadzenie do ewolucyjności
2017
This article introduces a vision of the new politics that emerges from my recent book Tractatus Politico‑Philosophicus. The Tractatus discusses a number of topics. To name just a few, these are: politics, human nature, the state, freedom, solidarity, democracy, civilization, family and marriage, power, international relations, war and peace. Also, it introduces new words, such as sophocracy, ennobled democracy; nativeculturalism (an alternative to multiculturalism); or parentsexuality, a privileged form of sexuality. It addresses many issues that concern today’s political thinkers. The main objective of my work is to demonstrate the necessity of, and provide a guide for, the redirection of …
Technicolor and new matter generations
2010
This work consists of an overview part and three research papers. The subject of this work is a class of models for dynamical electroweak symmetry breaking, and new generations of fermionic matter. An introductory overview of the standard model of electroweak interactions is given, as well as an overview of some of the recent developments in the field of walking technicolor models. We study some recently proposed models for dynamical electroweak symmetry breaking, namely the minimal walking technicolor (MWT) and next to minimal walking technicolor (NMWT) model. We show that, as a result of cancellation of the global and gauge anomalies associated with the technicolor sector, a non sequentia…
Global and local interactions in football: Comparing the development paths of Finland and Hungary
2018
The aim of this study is to increase understanding of football’s global and local contexts. More specifically, the development paths of Finnish and Hungarian football are explored and compared in four research articles from different perspectives within a global framework. These viewpoints, in addition to a historical-sociological overview in the article I, cover closely interrelated phenomena observable in the landscape of top-level football: the organization of elite youth football, the professionalization of players and the development of football stadiums. The main research question of the study is as follows: In what way have glocal interactions in men’s football shaped the development…
Multivalent N-donor ligands for the construction of coordination polymers and coordination polymer gels
2018
This work describes the synthesis and characterisation of several multivalent N-donor ligands and their coordination compounds and the use of these ligands in the construction of coordination polymers and coordination polymer gels. The project can be divided into two parts. The first part of the research is focused on the coordination chemistry of ring-substituted biimidazoles in acidic media. The dependence of the formation of ion pairs and zwitterionic, especially zinc and copper containing coordination compounds on the pH of the reaction medium and ring-substituents of the ligand were examined. The second part of the study deals with the preparation of Ag, Zn and Cu coordination polymers…
Mesoporous silica microparticles gated with a bulky azo derivative for the controlled release of dyes/drugs in colon.
2018
[EN] Mesoporous silica microparticles were prepared, loaded with the dye safranin O (M-Saf) or with the drug budesonide (M-Bud) and capped by the grafting of a bulky azo derivative. Cargo release from M-Saf at different pH values (mimicking those found in the gastrointestinal tract) in the absence or presence of sodium dithionite (a reducing agent mimicking azoreductase enzyme present in the colon) was tested. Negligible safranin O release was observed at pH 6.8 and 4.5, whereas a moderate delivery at pH 1.2 was noted and attributed to the hydrolysis of the urea bond that linked the azo derivative onto the external surface of the inorganic scaffold. Moreover, a marked release was observed w…
Expansion and Compression of a Helicate with Central Diol-Units as Stereocontrolling Moieties
2022
The dicatechol ester ligand 2-H4 forms the compressed helicate Li4[(2)3Ti2] which upon removal of the internally bound lithium cations expands. In the compressed form, the chiral diol units control the stereochemistry of the complex which is lost upon expansion of the system. peerReviewed
Identified charged particle flow and unfolding event-by-event flow in heavy ion collisions
2013
Yksi raskasionitörmäyksen ominaisuuksista on syntyvän matalaenergisen hiukkasvirran epäisotrooppisuus. Tämä epäisotrooppisuus karakterisoidaan useimmiten Fourierin sarjakehitelmän ja sen kertoimien avulla. Tässä työssä tutkin kahta puolta hiukkasvirrassa. Ensimmäinen on tunnistettujen hiukkasten virta ja niin sanottu kvarkkilukuskaalaus. RHIC-kiihdyttimellä on huomattu, että skaalaamalla hadronien ja mesonien havaitut isotrooppisuuskertoimet kvarkkiluvuilla erot eri hiukkasten välillä häviävät lähes kokonaan. Tämän tulkittiin tarkoittavan sitä, että hiukkasvirran kehitykseen vaikuttaa lähinnä törmäyksen partoninen vaihe ja hadronisaation jälkeisellä vaiheella ei ole vaikutusta. Toinen puoli…
