Electron beam-induced immobilization of laccase on porous supports for waste water treatment applications.

The versatile oxidase enzyme laccase was immobilized on porous supports such as polymer membranes and cryogels with a view of using such biocatalysts in bioreactors aiming at the degradation of environmental pollutants in wastewater. Besides a large surface area for supporting the biocatalyst, the aforementioned porous systems also offer the possibility for simultaneous filtration applications ...

Low energy electron beam induced vacancy activation in GaN

Experimental evidence on low energy electron beam induced point defect activation in GaN grown by metal-organic vapor phase epitaxy (MOVPE) is presented. The GaN samples are irradiated with a 5–20 keV electron beam of a scanning electron microscope and investigated by photoluminescence and positron annihilation spectroscopy measurements. The degradation of the band-to-band luminescence of the i...

In situ growth optimization in focused electron-beam induced deposition

We present the application of an evolutionary genetic algorithm for the in situ optimization of nanostructures that are prepared by focused electron-beam-induced deposition (FEBID). It allows us to tune the properties of the deposits towards the highest conductivity by using the time gradient of the measured in situ rate of change of conductance as the fitness parameter for the algorithm. The e...

Catalyst supports for polymer electrolyte fuel cells.

A major challenge in obtaining long-term durability in fuel cells is to discover catalyst supports that do not corrode, or corrode much more slowly than the current carbon blacks used in today's polymer electrolyte membrane fuel cells. Such materials must be sufficiently stable at low pH (acidic conditions) and high potential, in contact with the polymer membrane and under exposure to hydrogen ...

Growth and characterization of CNT Forests using Bimetallic Nanoparticles as Catalyst

The synthesis of Fe, Fe-Pt and Fe-Co nanoparticles were carried out using the bottom-up polyol process using standard ari free techniques. Using these nanoparticles, multiwalled carbon nanotubes were synthesized in an atmospheric pressure plasma enhanced chemical vapor deposition(APPECVD) process with a mixture of helium and acetylene gases. The APPECVD process produced dense carbon nanotube fo...
