SUBSTANCE: part of air which is close to critical section of nozzle blades of fast gas current laser and which volume is 50-80 percents is supplied to combustion chamber together with carbon-containing fuel. Said air is burnt under condition of one additional volume excess of air. Another ...
Water vapor becomes important here too, because while O2and N2don’t absorb infrared, water vapourdoes.Water vapour has a relatively short lifetime in our atmosphere(about ten days compared to a decade for carbon dioxide) so its overall warming effect is less. Except that once carbon dioxide ...

light-emitting diodes (LEDs) have dominated lighting study and market share because of their energy efficiency, long-lifetime, reliability, and wide application range, such as in LED-based solid-state lighting1. In general, commercial white LEDs (WLEDs) are generated...
The lifetime of singlet oxygen in supercritical fluid carbon dioxide, under these conditions, extrapolated to the value in the absence of ground state molecular oxygen, was found to be 5.1 ms (at 150 kg/cm2 and 41 °C). The factors determining the lifetime of O2(a1Δg), in ...
the steady acidification of ocean waters.The study published in the journal Global Change Biology finds that sea grass forests can raise pH levels in coastal waters.As they perform photosynthesis (光合作用),they remove carbon dioxide from the water,counteracting the acidifying effect ...

Here, we present a new technique for measurements of temperature in flames based on infrared laser absorption of nascent carbon dioxide. For gaseous environments, temperature is commonly measured with thermocouples due to their simplicity and versatility. In flames, however, thermocouple-based point-...
presence of Ni. The extended lifetime lays the groundwork for the subsequent multi-electron transfer reaction. Moreover, the differentiation in the respective [CO2•−]adradical transient kinetics and characteristic spectra across Au, Cu, and Ni systems suggest diverse stabilization behavior and ...
3e). A longer lifetime of this reactive intermediate would increase the probability of C–C coupling between the intermediates. Empirical kinetic model Although the DFT computations provide insight into the central role of EMIM-BF4 in CO2 activation, the volcano-type dependence of the CO2RR ...
