TeO2–WO3 glasses coactivated with Er3+ and Yb3+ are prepared. The effect of Yb content on the efficiency of Er photoluminescence (PL) in the visible and IR spectral regions is studied. The highest PL efficiency is achieved at an Er : Yb atomic ratio of 1 : 1. The PL lifetime for the Er3+

Cross-linking additions of silicon carbide and waste material from ferroalloy production make it possible to increase the
heat-resistance index for mullite-containing refractories. For briquette specimens based on a charge containing aluminum powder
it reaches 45 thermal cycles (1300°C – water).

Problems arising with connecting the second exhaust-heat boiler to the first exhaust-heat boiler under load in the case of
flow circuits of combined-cycle plants of type PGU-450 are considered. Similar problems exist for two-boiler single-turbine
units of type PGU-325 and for two-boiler single-turbine units of traditional steampower plants with an output of 200–300 MW
upon connection of the second furnace of a two-furnace boiler to the operating first furnace. Analysis of the temperature-induced
stressed state and of the cyclic strength of thick-walled elements of the steam-water conduit of PGU-450 and of two-furnace
boilers of two-boiler single-turbine units with an output of 200–300 MW (the check valve, the inlet header of the water economizer)
is used for determining the steam temperature differences in the high-pressure conduits to the steam turbine and the order
of connection of the second exhaust-heat boiler to the operating fist one. Modes of enabling a two-boiler single-turbine unit
of a combined-cycle plant, which are most “rigid” from the standpoint of thermal strength, are determined.

1. | Adding vanadium and titanium to Fe–C–Mn–Cr-alloy leads to the formation of special cubic carbides and redistribution of chromium between the phase components: its content in the metal base increases. The distribution coefficient for chromium between special carbides and austenite decreases from 4.2–4.8 to 2.9–3.7. |
2. | Addition of vanadium and titanium promotes an increase in the electrode potential for alloy 300Kh27G11 from (–0.3) to (–0.2) V and a reduction in the corrosion rate in sea water from 0.052 to 0.040 and 0.032 mm/year respectively. |
3. | Alloys based on the system Fe–C–Mn–Cr containing vanadium and titanium are promising materials for preparing cast articles which exhibit high corrosion resistance in sea water. |

In this work, we present the first synthesis of dispirooxindole-β-lactams employing optimized methodology of one-pot Staudinger ketene-imine cycloaddition with N-aryl-2-oxo-pyrrolidine-3-carboxylic acids as the ketene source. Spiroconjugation of indoline-2-one with β-lactams ring is considered to be able to provide stabilization and wide scope of functionalization to resulting scaffolds. The dispipooxindoles obtained demonstrated medium cytotoxicity in the MTT test on A549, MCF7, HEK293, and VA13 cell lines, and one of the compounds demonstrated antibacterial activity against E. coli strain LPTD. 相似文献
