Thin films of iron with different thickness (⁓40-300 nm) were deposited on quartz and silicon substrates by using ion beam assisted deposition (IBAD) technique. The influence of film thickness and deposition rate on ...

Stabilizing nanoparticles on surfaces, such as graphene, is a growing field of research. Thereby, iron particle stabilization on carbon materials is attractive and finds applications in charge-storage devices, catalysis, ...

In this study, oil-soluble transition metal-based catalysts (Fe, Co, Ni) are proposed for catalyzing aquathermolysis reactions in steam injection process for heavy oil production to achieve in-situ upgrading of heavy oil. ...

The investigation of elemental composition, crystal structure and thermal behavior of vonsenite and hulsite from the Titovskoe boron deposit in Russia is reported. The structures of the borates are described in terms of ...

The multiple scattering theory is developed for y-quanta, passing through a crystal of arbitrary thickness in the if field. It is found that the y-photon, being absorbed and then emitted by the nuclear exciton can exchange ...

We present Mossbauer studies of the influence of excess iron atoms on the properties of ironbased superconductor Fe1.09SeO.5TeO.5. Mossbauer spectra were collected in a temperature range from liquid helium up to room ...

To investigate the local behavior of defects and mixed compositions in NbFeSb-based semiconductors, for improved thermoelectric efficiency, we have performed 93Nb and 121Sb NMR, as well as Mössbauer measurements, on pure ...

We show that the absorption transmission spectrum obtained by gamma-photons, detected with a delay, is narrowed due to the interference of the spectral components of the radiation field. Experimental spectra of absorption ...
