A possible mechanism for the emergence of an additional band gap due to a Ti–O–C bond in the TiO2–graphene hybrid system for enhanced photodegradation of methylene blue under visible light

Here we report the experimental and theoretical study of two TiO2–graphene oxide (TG) and TiO2–reduced graphene oxide (TR) composites synthesized by a facile and ecological route, for enhanced visible...

High peak power amplification in large-core all-solid Yb fibers with an index-elevated pump clad and a low numerical aperture core

We report on the development of large-core Yb-doped fibers with up to 100 µm core diameter and present first experimental results for high peak power amplification. The material for core and pump cladding...

The influence of the fiber drawing process on intrinsic stress and the resulting birefringence optimization of PM fibers

The propagation properties of optical fibers can be significantly influenced by intrinsic stress. These effects are often undesired but in some cases essential for certain applications, e.g. in polarization...

SPION@Polydehydroalanine Hybrid Particles

It is generally accepted that a protein corona is rapidly formed upon exposure of nanoparticles to biological fluids and that both the amount and the composition of adsorbed proteins affect the solution...

Biomarkers in Archaeology – Land use around the Uyghur Capital Karabalgasun, Orkhon Valley, Mongolia

In order to investigate the use to which recently discovered and recorded large oval enclosures surrounded by a low wall and ditch were put, a series of topsoil samples were taken and subjected to an analysis...

Improving the sensitivity of optically pumped magnetometers by hyperfine repumping

Most optically pumped magnetometers based on alkali atom vapor cells and pumped by a single narrow-band laser suffer from a loss of signal since atoms become trapped in the ground state hyperfine states...

PEDOT:PSS emitters on multicrystalline silicon thin-film absorbers for hybrid solar cells

We fabricated an efficient hybrid solar cell by spin coating poly(3,4-ethylene-dioxythiophene):polystyrenesulfonate (PEDOT:PSS) on planar multicrystalline Si (mc-Si) thin films. The only 5 µm thin Si...

Minimization of flux-trapping in SQUID magnetometers during cool-down.

Removal of step-edges in SQUID-based geomagnetic data.

SQUID-based setup for the absolute measurement of magnetic fields.
