Optimization of solution-processed oligothiophene:fullerene based organic solar cells by using solvent additives
(Beilstein Institut, 2013-10)
The optimization of solution-processed organic bulk-heterojunction solar cells with the acceptor-substituted quinquethiophene DCV5T-Bu-4 as donor in conjunction with PC61BM as acceptor is described. Power conversion ...
STM study on the self-assembly of oligothiophene-based organic semiconductors
(Beilstein Institut, 2011-11)
The self-assembly properties of a series of functionalized regioregular oligo(3-alkylthiophenes) were investigated by using scanning tunneling microscopy (STM) at the liquid-solid interface under ambient conditions. The ...
Metallic thin films on stepped surfaces: lateral scattering of quantum well states
(IOP Publishing, 2014-12-10)
Quantum well states of Ag films grown on stepped Au(111) surfaces are shown to undergo lateral scattering, in analogy with surface states of vicinal Ag(111). Applying angle resolved photoemission spectroscopy we observe ...
Optimizing the extraction process of natural antioxidants from chardonnay grape marc using microwave-assisted extraction
(2019-03-21)
The aim of this work was to extract phenolic compounds from Chardonnay grape marc employing a
microwave-assisted extraction (MAE). Firstly, the effect of solvent concentration (30–60%), solid mass
(1.0–2.0 g) and extraction ...
