Sublayer-Enhanced Growth of Highly Ordered MnGe Thin Film on Si(111).

MnGe epitaxial thin films previously grown mainly on Ge substrate have been synthesized on Si(111) using the co-deposition of Mn and Ge at a temperature of 390 °C. RMS roughness decreases by almost a factor of two in the transition from a completely polycrystalline to a highly ordered growth mode. This mode has been stabilized by changing the ratio of the Mn and Ge evaporation rate from the stoichiometric in the buffer layer.

Phosphazene-Containing Epoxy Resins Based on Bisphenol F with Enhanced Heat Resistance and Mechanical Properties: Synthesis and Properties.

Organophosphazenes are of interest due to the combination of increased mechanical and thermal properties of polymer materials obtained with their use, however, they are characterized by a complex multi-stage synthesis. Moreover, the high viscosity of phosphazene-containing epoxy resins (PhER) makes their processing difficult. To simplify the synthesis of PhER, a one-step method was developed, and bisphenol F was chosen, which also provided a decrease in viscosity.

Asymmetric Interfaces in Epitaxial Off-Stoichiometric FeSi/Ge/FeSi Hybrid Structures: Effect on Magnetic and Electric Transport Properties.

Three-layer iron-rich FeSi/Ge/FeSi (0.2 < < 0.64) heterostructures on a Si(111) surface with Ge thicknesses of 4 nm and 7 nm were grown by molecular beam epitaxy.

Structural, Optical, and Electronic Properties of Cu-Doped TiNO Grown by Ammonothermal Atomic Layer Deposition.

Copper-doped titanium oxynitride (TiNO) thin films were grown by atomic layer deposition (ALD) using the TiCl precursor, NH, and O at 420 °C. Forming gas was used to reduce the background oxygen concentration and to transfer the copper atoms in an ALD chamber prior to the growth initiation of Cu-doped TiNO. Such forming gas-mediated Cu-doping of TiNO films had a pronounced effect on their resistivity, which dropped from 484 ± 8 to 202 ± 4 μΩ cm, and also on the resistance temperature coefficient (TCR), which decreased from 1000 to 150 ppm °C.

[Hybrid technologies in treatment of a patient with vascular graft infection].

Presented in the article are advantages of various methods of treatment of periprosthetic infection which continues to be one of the most challenging problems in modern vascular surgery. We describe herein a clinical case report regarding a patient with late infection of a bifurcated aortofemoral bypass graft. The infectious complication manifested itself by a periprosthetic infiltrate in the area of the distal anastomosis.
