Catalytic Properties of a Novel Raney-Nickel Foam in the Hydrogenation of Benzene
The catalytic properties of a novel Raney-Nickel mold were investigated in the liquid-phase hydrogenation of benzene and compared to commercially available Raney-Nickel. The novel Raney-Nickel catalyst showed ...

Aluminum–germanium wafer bonding of (AlGaIn)N thin-film light-emitting diodes
Eutectic aluminum–germanium wafer bonding was used to fabricate (AlGaIn)N thin-film light-emitting diodes (LEDs). Wafer bonding was carried out on 2″ wafer level at a bond temperature of 470 °C using patterned...

Implantation Studies on Silicon-Doped GaN
Silicon-doped GaN layers grown by low-pressure metalorganic vapor-phase epitaxy with Si concentrations ranging from 2 × 1017 Si/cm3 to 9.2 × 1018 Si/cm3 were investigated by means of the perturbed angular correla...

Increased Conversion in the Heck Reaction Under Irradiation with Light
Irradiation with light (UV–vis and visible) was shown to increase the rate of the Heck reaction at 90–140 °C using both heterogeneous and homogeneous catalysts. The photoreduction of Pd(II) is most likely the ...

GaInAs/AlAsSb Quantum Cascade Lasers: A New Approach towards 3-to-5 μm Semiconductor Lasers
At present GaInAs/AlInAs based quantum cascade (QC) lasers represent the state-of-the-art with respect to the short-wavelength (< 5 μm) performance of the QC laser concept. This performance, however, is intrin...

Controlled Distribution of Solid Catalysts into Two Immiscible Liquid Phases – Synthesis and Catalytic Applications
A new concept for the separation of heterogeneous catalysts is presented. Against gravity, surface modified catalysts are located only in one of two immiscible liquid phases. The catalyst phase can be separate...

Ultrafast Coherent Exciton Spectroscopy and Carrier Control in Quantum Structures
Interference effects between ultrafast laser pulses become important when the relative phase is precisely determined. The response of an optical system then shows strong oscillations when the pump-pulse separa...
