Advanced Materials for Organic Photonics

V oblasti nových nízkomolekulárních organických materiálů patří deriváty difenyldiketopyrrolopyrrolu (DPP), používané dříve jako barviva a pigmenty, k objektům vysokého zájmu pro jejich potencionální aplikace v moderních technologiích. Studium jejich optických vlastností ve vztahu k jejich chemické struktuře umožní využití jejich vysokého potenciálu ve vývoji pokročilých inteligentních materiálů. Přehled chemických a fyzikálních vlastností DPP derivátů a zhodnocení současného stavu řešené problematiky jsou uvedeny v teoretické části této práce. Tři hlavní procesy studované v této práci jsou: klasická absorpce a emise, dvoufotonová absorpce (TPA) a zesílená spontánní emise (ASE). Výsledky budou diskutovány a shrnuty ve dvou částech: první zahrnuje první dvě výše zmíněné oblasti a druhá problematiku zesílené spontánní emise.Among low molecular organic materials, diphenyl-diketo-pyrrolopyrrole (DPP) derivatives used earlier as dyes are of high interest in modern technologies. The study of their optical properties related to their chemical structure will provide more information on the later relationship and comfort the high potential of DPP derivatives in the making of more performant smart materials. An overview of their chemical and physical properties is described in the theoretical part and followed by the state of the art in the field of interest concerning this thesis. The three main processes studied in this work are: The classic absorption and emission, the two photon absorption (TPA) and the amplified spontaneous emission (ASE). The results will be discussed and summarized in two parts: The first concerning the one and the two photon absorption and the second the amplified spontaneous emission.

Discovering the Value of Multidisciplinary Approaches to Research: Insights from a Sabbatical

In this informal report, I outline my research efforts, collaborations, and other experiences while participating in the Naval Research Laboratory (NRL)'s Advanced Graduate Research Program (AGRP), aka Sabbatical, from October 2008 through September 2009. This report is in no way intended to present the technical details of the various research projects, but rather a broad overview of the small ways my efforts may have contributed to ongoing research. I wish to convey to the reader the value of multidisciplinary approaches to scientific research and how the AGRP facilitates these opportunities.Comment: 13 pages, 5 figure

A New Supersensitive Flame Detector and its Use for Early Forest Fire Detection

A new flame detector, three orders of magnitude more powerful than the existing ones, is presented. This detector needs to be mass-produced for its use in order to be incorporated in an early forest fire detection system. A project able to implement its use to overcome the forest fire emergency is described

Ghent University Technology Park : from a local initiative towards an essential component of the Ghent knowledge innovation ecosystem

Using the case of the Ghent University and its Technology Park, we will illustrate how changing policies and practices at the level of the university concerning research valorization have an impact on our science park. We will also demonstrate how the evolving nature of our science park has a clear impact on the university, as the science park becomes more and more an integral part of the university knowledge eco-system. We will also highlight the involvement of Ghent University in the Korea Songdo Global University Campus Project
