The effect of vacuum annealing on the structure and properties of the electrically conductive a-CN coating
Electrically conductive amorphous carbon nitride (a-CN) coatings were deposited onto various substrates by pulsed vacuum-arc sputtering of a graphite cathode with simultaneous irradiation of the substrate with nitrogen ions. Deposition temperature was less than 60 ◦C. We investigated the effect of vacuum annealing at a temperature of 600◦С on the elemental composition, structure, electrical and optical properties of the obtained films. It was found that the elemental composition of the coating practically does not change over the thickness of the coating after annealing, while the remaining characteristics change significantl
Инфракрасная навигация в годы войны
The first samples of domestic infrared (hereinafter-IR) navigation devices were created in the late 30-ies of XX century in NII‑9 (Leningrad) and VEI (Moscow). Since the beginning of 1941 their production for the Navy and Air Force was organized, as the article describes in detail. After the war, the development of IR devices continued resulting in full coverage of the range of electromagnetic waves.Первые образцы отечественных инфракрасных (ИК) навигационных приборов были созданы в конце 30-х годов ХХ века в НИИ‑9 (Ленинград) и ВЭИ (Москва). С начала 1941 года организован их выпуск для флота и авиации, о чем подробно рассказывает статья. В послевоенное время это направление продолжало развиваться. В результате сейчас российские системы визуализации способны охватить весь диапазон электромагнитных волн

The Mesoproterozoic Rayner Province in the Lambert Glacier area: its age, origin, isotopic structure and implications for Australia–Antarctica correlations
<p>Within the Rayner Province in the Lambert Glacier area, two Proterozoic lithotectonic zones are distinguished, which differ
in age and lithology. In the Fisher Zone, a significant juvenile component (ε<sub>Nd</sub>(<em>t</em>)=+2 to +4) is represented by mafic, intermediate and felsic plutonic and volcanic rocks; the tectonomagmatic processes were
concentrated at <em>c.</em> 1400–1200 Ma. In the Beaver Zone, orthogneisses record multiple emplacement, metamorphism and ductile deformation at <em>c.</em> 1150–930 Ma. New U–Pb SHRIMP-II zircon ages (<em>c.</em> 1140 Ma and 1095 Ma – protolith emplacement; <em>c.</em> 950–850 and <em>c.</em> 540 Ma – metamorphism), chemical and Sm–Nd isotopic data indicate that both zones have their continuations in the eastern
Amery Ice shelf coast. The Rayner Province has some geological features in common with the Albany-Fraser Orogen in Western
Australia, suggesting that these regions evolved in similar tectonic environments at <em>c.</em> 1400–1300 Ma, followed by steady closure, from east to west, of the ocean that separated the Mawson Continent from Western
Australia.
