The study explored how authentic leadership (AL) affected employees' work engagement (WE) both directly and through the mediating role of employees' Psychological Capital (PsyCap). Using a correlation research design, the authors collected valid responses from 304 employees across organizations through a paper survey in Beijing (China). The results showed both authentic leadership and PsyCap positively...
We report on the fabrication and characterization of both flat and patterned c-Si solar cells on glass. We use epitaxial layers grown by plasma enhanced chemical vapor deposition at low temperature (T<200°C), and anodic bonding on glass substrate. Inverted nanopyramids are fabricated by nanoimprint lithography and wet etching in alkaline solution. With 3µm-thick c-Si layers, the performances achieved...
Simultaneous measurements of water and CO2 isotopologue ratios were performed using laser absorption spectroscopy in combination with Kalman filtering at 2.73 μm. The isotopic compositions of eH2O and eCO2 in breath gas were analyzed.
Bi25FeO40 powders have successfully been synthesized by simple hydrothermal method. The effect of the concentration of mineralizer and stoichiometry on the prepared samples was investigated. With the UV-Vis spectra, Bi25FeO40 powders have a broad absorption band in the range of 400-600 nm and a good visible-light-response ability. Photo-catalytic activity of Bi25FeO40 powders was evaluated by the...
Ethylene (C2H4) absorption line intensity at 6172.95 cm-1 was determined for trace gas detection. C2H4 trace concentration measurements were performed using quartz enhanced photoacoustic spectroscopy (QEPAS) with a sensitivity of 1.3 ppmv (1sigma) for tau=1s time constant. The effect of modulation frequency accuracy on QEPAS signal was investigated.
Badano procesy zmiany stanu ładunkowego jonów chromu monokryształów Mg₂SiO₄:Mg, Cr pod wpływem wygrzewania w tlenie oraz w powietrzu, a także w efekcie naświetlania kwantami gamma, porównując je do zmian obserwowanych w monokryształach Y₃Al₅O₁₂ :Mg, Cr. Powstawanie czterowartościowych jonów chromu w Mg₂SiO₄:Mg, Cr jest uwarunkowane nie tylko wyjściową koncentracją chromu, ciśnieniem parcjalnym tlenu...
