We apply a random forest regression algorithm and SHAP values to identify which features correlate most strongly with improved stability, and find that the most important properties extending the degradation onset are (i) the low number of hydrogen-bond donors and (ii) the small topological polar ...
Photoluminescence (PL) spectroscopy and time-correlated single photon counting (TCSPC) have been commonly used to understand charge collection efficiencies and identify charge transfer mechanisms. However, for HaP materials it has been difficult to determine exact values of electron/hole pair diffusion len...
The impurity standards are typically used to identify the impurity peaks observed and ensure system suitability in chromatographic procedures. If specified impurities are not available, a suitable “dirty” batch of the drug substance may be used as the reference standard, provided the individual ...
To identify the hydrogen trapping sites, the hydrogen desorption spectra were deconvoluted into four peaks, as shown in Fig. 2d for the ramping rate of 1000 °C/h. The activation energies of the individual peaks were determined to be 4.32 ± 0.31, 15.15 ± 4.10, 59.14 ±...
to be in very good agreement with standardex situXRD analysis. Moreover, the stress state of the film can be clearly identified also for very thin layers in the nanometre range, well below the limit of conventional XRD analysis. Finally, the MOSS diagnostic of oxide materials has been ...
FT-IR spectroscopy measurements were carried out to identify the formation of biologically synthesized silver nanoparticles (Figure S2). Figure S2 shows the presence of three bands at 1763, 1652, and 1386 cm−1. The strong absorption at 1763 cm−1 is due to the carbonyl stretching vibration...
