Synthesis of the new ring system 6,8-dihydro-5H-pyrrolo[3,4-h]quinazoline
2009
Abstract A convenient synthesis of the pyrrolo[3,4- h ]quinazoline ring system is reported. Our synthetic approach consisted of the annelation of a pyrimidine ring to an isoindole moiety using tetrahydroisoindole-4-ones as building blocks. The antiproliferative activity of the new compounds was investigated and one of them showed antitumor activity against all the 59 tested cell lines at micromolar concentrations (1.46–18.4 μM).

Wideband modeling of cascaded H-plane waveguide junctions using the generalised impedance matrix representation
2009
A strong interest in H-plane waveguide components composed of a large number of cascaded planar junctions is recently renewed. Therefore, the more efficient development of full-wave analysis tools of such devices is again receiving consideration, specially for its potential use within modern design tools. A novel technique for providing the wideband generalised impedance matrix representation of the inductive devices in the form of pole expansions, thus extracting the most expensive computations from the frequency loop is proposed. For such purpose, the whole device is first decomposed into simpler building blocks, i.e. planar junctions and uniform waveguides, which are modelled in terms of…
Colloidal Nanoplatelet/Conducting Polymer Hybrids: Excitonic And Material Properties
2016
WOS:000370678700053 Here we present the first account of conductive polymer/colloidal nanoplatelet hybrids. For this, we developed DEH-PPV-based polymers with two different anchor groups (sulfide and amine) acting as surfactants for CdSe nanoplatelets, which are atomically flat semiconductor nanocrystals. Hybridization of the polymers with the nanoplatelets in the solution phase was observed to cause strong photoluminescence quenching in both materials. Through steady-state photoluminescence and excitation spectrum measurements, photoluminescence quenching was shown to result from dominant exciton dissociation through charge transfer at the polymer/nanoplatelet interfaces that possess a sta…
Rinnakkaislaskentamallien arviointi : Intel Threading Building Blocks
2013
Moniydinprosessoreiden ollessa jo normi on rinnakkaislaskennasta tullut arkipäivää yhä useammalle ohjelmoijalle. Rinnakkaislaskenta on hankalaa hahmottaa ja toteuttaa, joten tarvitaan uusia korkeamman abstraktiotason rinnakkaislaskentamalleja tukemaan rinnakkaislaskennan yleistymistä. Tässä tutkielmassa luomme mallin rinnakkaislaskentamallien arviointiin kahdeksasta eri näkökulmasta. Sen jälkeen tutustumme Intel Threading Building Blocks (TBB) -rinnakkaistuskirjastoon, joka lupaa tehdä rinnakkaislaskennan toteuttamisesta helpompaa siirtämällä rinnakkaistuksen perusmekanismeja pois ohjelmoijan vastuulta. Lopuksi arvioimme TBB:tä aiemmin luomamme mallin pohjalta. Toteamme, että TBB täyttää hy…
