Dialogicality Of Faith In The Attitudes Of Thomáš Halik
No full textW artykule pragnie się przedstawić główne myśli T. Halika – znanego czeskiego i europejskiego intelektualisty, rzymskokatolickiego kapłana, rektora kościoła akademickiego w Pradze – na temat potrzeby budowania chrześcijańskiej wiary, w jej dialogicznym wymiarze. Filozof i zarazem teolog praski – T. Halik – przez zgłębianie dialogiczności wiary, pragnie zwrócić uwagę, że w dzisiejszych czasach, przyszłość chrześcijaństwa, będzie się zawierała w podróży w głąb swego duchowego dojrzewania, ze wszystkimi zawartymi w niej kryzysami i wewnętrznymi konfliktami.In this article the author wishes to present the main thoughts of T. Halik, a well-known Czech and European intellectual, Roman Catholic priest, rector of the academic church in Prague, on the need to build Christian faith in its dialogical dimension. At the same time, the philosopher and the Prague theologian, T. Halik, would like to draw attention to the fact that nowadays, the future of Christianity will be contained in the journey into its spiritual maturation, with all its crises and internal conflicts
Wakefulness As The Method Of Feeling Secure In The Thoughts Of Thomas Halik
No full textPrezentowany artykuł ukazuje problem zdobywania poczucia bezpieczeństwa w myśli czeskiego myśliciela T. Halika. Jest to złożone zagadnienie, ponieważ Halik sprzeciwia się standardowemu postrzeganiu tego problemu. Dla niego bezpieczeństwo nie jest stanem braku zagrożenia, ale przytomnym i odważnym stawianiem czoła trudnościom. Bycie czujnym i otwartym na transcendencje wymaga poświęcenia, ale przynosi owoce w postaci stopniowego odnajdywania pełni życia. Autentyczne życie obecne jest w przytomnym, ale również otwartym na transcendencje sposobie egzystowania, co zbliża T. Halika do filozofów poszukujących ludzkiej głębi. Zaletą artykułu jest ukazanie omawianego problemu w kompleksowym ujęciu, które uwzględnia wymiar teologiczny, filozoficzny, oraz psychologiczny. Autor artykułu odwołuje się również do tych myślicieli, którzy inspirowali T. Halika. Wśród nich warto wymienić Józefa Tischnera, Emmanuela Levinasa, Friedricha Nietzschego, Martina Bubera, czy Zygmunta Freuda.The presented article shows the problem of acquiring a sense of security in philosophy of the Czech thinker T. Halik. This is a complex issue because T. Halik is opposed to the standard perception of this problem. For him, security is not a state of no threat, but a conscious and courageous face to face difficulties. Being vigilant and open to transcendental requires sacrifice, but it brings fruit in the form of gradually finding the fullness of life. Authentic life is present in a conscious, but also open to transcendence way of existence, which brings Halik closer to philosophers seeking human depth. The main advantage of the article is the presentation of the discussed problem in a comprehensive approach, which takes into account the theological, philosophical and psychological dimensions. The author of the article also refers to those thinkers who inspired T. Halik. These include Józef Tischner, Emmanuel Levinas, Friedrich Nietzsche, Martin Buber and Zygmunt Freud

No full textOptische Eigenschaften gemischter, selbstorganisierter Monolagen auf Metalloxid Nanopartikeln
No full textThis work examines the relationship between the morphology of self-assembled monolayers (SAM) on metal oxide nanoparticle surfaces and the thereof resulting optical properties. The SAM equals here the ligand shell of nanoparticles and is described as ‘first’ shell in this context. Therefore, dyes that are based on compounds of the polycyclic aromatic hydrocarbon (PAH) class are immobilized in SAMs. The aim is to gain an understanding of the most important factors, which have an impact on the optical properties of PAHs in SAMs.
First, nanoparticles (NPs) were functionalized with varying mixtures of PAHs, as marker molecules, and different phosphonic acid derivatives (PA-M), to mimic different solvent surroundings around the PAHs. Thereby, the PAHs were introduced either via a copper(I)-catalyzed alkyne-azide cycloaddition reaction or directly as phosphonic acid derivative. Depending on the chemical composition of PA-M an influence on the PAHs fluorescence, comparable to the influence of solvents polarity, is expected. The application of mixed SAMs allows the control of PAHs aggregation on NP surfaces similar to PAH aggregation behavior in solution. An impact on the SAMs (or first shell) structure reveals depending on the molecular structures of the respective PA-Ms or PAH, and consequently on the optical properties of the NPs. The impact of the surrounding environment on immobilized PAHs in SAMs, being the control of PAH aggregation and PA-Ms flexibility, prevails the impact of PA-Ms ‘polarity’ as expected from solution.
Second, for the further inhibition of PAH aggregation a ‘second’ non-covalently bound shell was applied. It provides a complete ‘solvent shell’ around the PAHs. Thereby, amphiphiles intercalate into the first shell of the NPs. The application of a second shell aims towards a fluorescence preservation of PAHs in ‘quenching’ environments, by protecting the PAHs with the complete formed second shell. Depending on the type of PAH aggregation, the second shell formation provides a tool to impact PAH aggregation in the first shell. Thereby, the morphology of the first NP shell and its interaction with a corresponding amphiphile, the molecular structure of the applied PAHs, the amphiphiles and possible communication within them, explain the resulting overall optical features of NP. Hence, both an enhancement but also a quenching of fluorescence intensity are possible upon applying a second shell.
Third, both the first and second shell NPs were transferred to solid state substrates, supporting the fact that molecular level engineering strongly impacts on material properties on the mesoscale.
Summarizing the aforementioned, the embedding of PAHs into a defined chemical environment provided by the first and second shell of NPs is possible. Thereby, several factors influence on the respective fluorescence behavior. A complete shell can consequently provide information on the actual chemical surrounding of PAHs linked to NPs surfaces.Diese Arbeit befasst sich mit dem Zusammenhang zwischen der Morphologie selbstassemblierter Monolagen (SAM) auf metalloxidischen Nanopartikeloberflächen und der daraus resultierenden optischen Eigenschaften. Die SAM entspricht hier der Ligandenhülle eines Nanopartikels und wird als „erste“ Nanopartikelhülle bezeichnet. Mit dem Ziel die optischen Eigenschaften zu kontrollieren und ein Verständnis für die hauptsächlichen Einflussfaktoren zu gewinnen, werden Farbstoffe, hier verschiedene Polyzyklische Aromatische Kohlenwasserstoffe (PAK), in SAMs immobilisiert.
Dafür werden Nanopartikel mit Mischungen verschiedener PAKs, als molekulare Marker, und unterschiedlichen Phosphonsäurederivaten (PA-M) funktionalisiert. Verschiedene chemische Umgebungen in SAMs werden durch entsprechend ausgewählte PA-Ms simuliert. Die PAKs werden entweder indirekt über eine Huisgen-Cycloaddition oder direkt als Phosphonsäurederivat in SAMs eingebunden. In Abhängigkeit von der chemischen Zusammensetzung der gewählten PA-M wird ein Einfluss auf die PAK Fluoreszenzeigenschaften erwartet, vergleichbar zu dem Fluoreszenzverhalten von PAKs in Lösungsmitteln unterschiedlicher Polarität. Die resultierenden optischen Eigenschaften der „ersten“ Nanopartikelhülle hängen jedoch stark von der jeweiligen verwendeten PAK und PA-M Molekülstruktur ab. Durch die Anwendung gemischter SAMs wird das PAKs Aggregationsverhalten auf Nanopartikeloberflächen kontrolliert, vergleichbar zu variierenden PAK Konzentrationen in Lösung. Durch eine geeignete PA-M Wahl, als Umgebung immobilisierter PAKs in SAMs, wird zusätzlich die gesamte SAM Flexibilität beeinflusst. Somit werden die optischen Eigenschaften von SAMs auf Nanopartikeloberflächen gezielt gesteuert. Der Einfluss der Molekülstruktur von PA-M und PAKs überwiegt in diesem Fall dem erwarteten Einfluss einer nachgeahmten Lösungsmittelpolarität.
Durch die Möglichkeit nicht kovalenter Wechselwirkungen zwischen Amphiphilen und der „ersten“ Nanopartikelhülle, wird eine „zweite“ Nanopartikelhülle aufgebaut. Diese bietet die Möglichkeit die PAK Aggregation weiter zu beeinflussen und bildet zusätzlich eine vollständige „Lösungsmittelhülle“ um die jeweiligen PAKs. Durch die „zweiten“ Nanopartikelhülle sollen die Fluoreszenzeigenschaften der PAK in fluoreszenzquenchenden chemischen Umgebungen erhalten bleiben. Je nach PAK Aggregationstyp, beeinflusst die Ausbildung einer „zweiten“ Hülle die PAK Aggregation in der „ersten“ Hülle. Dabei spielt die Morphologie der „ersten“ Nanopartikelhülle, deren Interaktion mit einem dazugehörigen Amphiphil, aber auch die Molekülstruktur der eingesetzten PAKs, des Amphiphils und deren mögliche Kommunikation eine große Rolle bei der Deutung der resultierenden optischen Nanopartikeleigenschaften. Je nach Kombination kommt zu einer Erhöhung oder Erniedrigung der Fluoreszenzintensität.
Zu Letzt werden Nanopartikel mit sowohl „einer“ als auch mit „zwei“ Hüllen in eine mesoporöse Schicht überführt, wobei die Nanopartikeleigenschaften erhalten bleiben. Damit zeigt sich, dass die Beeinflussung von Eigenschaften auf molekularer Ebene einen großen Einfluss auf die umfassenden Materialeigenschaften hat.
Die Einbettung der PAK in eine definierte chemische Umgebung, die hier durch die „erste“ und „zweite“ Nanopartikelhülle dargestellt wird, ist somit möglich. Je nach System beeinflussen verschiedene Faktoren das jeweilige Fluoreszenzverhalten. Eine komplett ausgebildete „zweite“ Nanopartikelhülle kann somit als Sensor dienen, um Informationen über die tatsächliche chemische Umgebung immobilisierter PAKs auf Nanopartikeloberflächen zu gewinnen

No full textFrom the underground church to freedom
No full text"International best-selling author and theologian Tomas Halik shares for the first time the dramatic story of his life as a secretly ordained priest in Communist Czechoslovakia. Inspired by Augustine's candid presentation of his own life, Halik writes about his spiritual journey within a framework of philosophical theology; his work has been compared to that of C. S. Lewis, Thomas Merton, and Henri Nouwen. Born in Prague in 1948, Halik spent his childhood under Stalinism. He describes his conversion to Christianity during the time of communist persecution of the church, his secret study of theology, and secret priesthood ordination in East Germany (even his mother was not allowed to know that her son was a priest). Halik speaks candidly of his doubts and crises of faith as well as of his conflicts within the church. He worked as a psychotherapist for over a decade and, at the same time, was active in the underground church and in the dissident movement with the legendary Cardinal Tomasek and Vaclav Havel, who proposed Halik as his successor to the Czech presidency. Since the fall of the regime, Halik has served as general secretary to the Czech Conference of Bishops and was an advisor to John Paul II and Vaclav Havel. Woven throughout Halik's story is the turbulent history of the church and society in the heart of Europe: the 1968 Prague Spring, the occupation of Czechoslovakia, the self-immolation of his classmate Jan Palach, the "flying university," the 1989 Velvet Revolution, and the difficult transition from totalitarian communist regime to democracy. Thomas Halik was a direct witness to many of these events, and he provides valuable testimony about the backdrop of political events and personal memories of the key figures of that time"-
