Figure 1(b) shows the UV-visible spectra of the YBCO gel films irradiated for different period of times. When the time of irradiation increased, the peak intensities of the UV absorption spectra of the YBCO gel film gradually decreased and were non-existent after 60 minutes of irradiation...
The presence of Li, in a molar ratio of 1:1, promoted mainly the hydroformylation reaction and the n-aldehyde formation rate on the Li-containing sample was six times higher than the non-promoted counterpart (TOFRh/Li = 462 h−1 vs. TOFRh = 69.6 h−1) and also the selectivity ...
The active power on the workday in the interval of the active program (8–14, 16–20) was greater than 2–2.5-times the active power on the week-nd day (Figures 24l and 25l), and the evolution of the active power differed from a day to another. There were also differences in the...
The compact fiber-optic probe shown in Figure 19 has extremely short response and recovery times. Fast temporal characteristics arise from the combination of hydrophilic coating, thin coating and circular geometry. The probe is flexible and compact, which lends itself to applications involving space-...
Switching power losses were also alleviated by reducing the number of switching times for power switches. The operation principle of the proposed inverter was described. A control scheme was suggested for regulating the DC-link voltage and the grid current. A 1.0 kW prototype inverter was designed...
