Abstract:
Since the discovery three decades ago, fullerenes as well as metallofullerenes have been extensively investigated. However, almost all known fullerenes follow the classical definition, that is, classic fullerenes are comprised of only pentagons and hexagons. Nowadays, more and more evidence, from both theoretical and experimental studies, suggests that non-classical fullerenes, especially heptagon-containing fullerenes, are important as intermediates in fullerene formation mechanisms. To obtain fundamental understandings of fullerenes and their formation mechanisms, new systematic studies shou

Abstract:
The thesis deals with a hypothetical project of a new building complex of a synagogue, a kosher restaurant and a community centre at the location of the former synagogue in Frýdek. The proposal includes a memorial of the destroyed synagogue and Jewish community, as well as the incorporation of the complex into the urban structure of the city. The project proposes a building distributed into three volumes. The restaurant and community centre are connected by an underground garage within a U-shaped floor plan. The buildings are axially symmetrical, white, with expressive rhythmical perforations

Abstract:
Nonbenzenoid carbocyclic rings are postulated to serve as important structural elements toward tuning the chemical and electronic properties of extended polycyclic aromatic hydrocarbons (PAHs, or namely nanographenes), necessitating a rational and atomically precise synthetic approach toward their fabrication. Here, using a combined bottom-up in-solution and on-surface synthetic approach, we report the synthesis of nonbenzenoid open-shell nanographenes containing two pairs of embedded pentagonal and heptagonal rings. Extensive characterization of the resultant nanographene in solution shows a

Abstract:
En les darreres dècades, l’ús d’anàlegs de nucleòsids (ANs) ha despertat un gran interès de recerca per a la teràpia antiviral i anticancerigen. La conformació i el plegament de la unitat de sucre dels nucleòsids tenen un paper crític en la modulació de la seva activitat biològica. En aquest context, s’han dissenyat i sintetitzat nous anàlegs de carbanucleòsids (ACNs) restringits conformacionalment per imitar el comportament conformacional de l’anell de furanosa natural. Els nucleòsids ciclohexenílics són un tipus prometedor de compostos antivirals, en què la substitució de l’àtom d’oxigen de

Abstract:
Acenes are a class of polycyclic aromatic hydrocarbons (PAH) with linearly fused benzene rings. They are widely considered as promising materials for organic and molecular electronics. However, larger molecules of this class possessing more than five rings are chemically extremely reactive and show a very low solubility. Hence, large acenes are difficult to handle, and the experimental data available to date is limited. The aim of this work is to show a very promising protocol of how acenes with different lengths can be stabilized and investigated on metallic surfaces. The experimental approac

The mechanism for focal atrial fibrillation (AF) originated from the pulmonary veins (PVs) is not currently known, but it could enhances automaticity or triggered activity or reentrant rhythms. It has been suggested that, due to lack of a critical mass of > 100 – 200 mm2, it would be difficult to induce AF in the heart of small animal (such as mice).
