An Optical Fiber Bundle Sensor for Tip Clearance and Tip Timing Measurements in a Turbine Rig
(MDPI, 2013-06)
When it comes to measuring blade-tip clearance or blade-tip timing in turbines, reflective intensity-modulated optical fiber sensors overcome several traditional limitations of capacitive, inductive or discharging probe ...
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 ...
Knock-on damage in bilayer graphene: Indications for a catalytic pathway
(American Physical Society, 2013-12-05)
[EN] We study by high-resolution transmission electron microscopy the structural response of bilayer graphene to electron irradiation with energies below the knock-on damage threshold of graphene. We observe that one type ...
