2-color IR spectroscopyspectroscopic thermometerultrafast thermal meltingSuperheating and bulk melting of neat H 2O ice are studied using 2-color IR spectroscopy with sub-picosecond pulses. The data are compared with similar experiments in 15 M HDO in D 2O. After calibration of our spectroscopic ...

The structure was confirmed by NMR and FT-IR spectroscopy (Figs. S1–S4). Electrospray ionization mass spectra were acquired with a Finnigan LCQ ion trap mass spectrometer (Finnigan, San Jose, CA). Sample solutions in 50:50 methanol/water were directly infused into the mass spectrometer with ...
Catalysts characterization, which includes powder X-ray diffraction (XRD), quasi in-situ X-ray photoelectron spectroscopy (XPS), H2-temperature-programmed reduction (H2-TPR), Ultraviolet-visible (UV-vis), Transmission electron microscopy (TEM), 1H NMR, in situ NH3-DRIFTS, in situ FT-IR and DF...
Electrons photoexcited in K3Ta3B2O12, an efficient photocatalyst for the water-splitting reaction driven by ultraviolet light, were observed using time-resolved IR absorption spectroscopy with microsecond resolution. When the catalyst was irradiated with 266 nm light pulses, a structureless absorption ...
for transmission electron microscopy (TEM) and energy-dispersive X-ray spectroscopy (EDS) analyses. Eight mineral grains (two pyroxene, three plagioclase, and three olivine grains) with different values of water content resulting from solar wind implantation were selected for detailed studies. The ...
To further explore the origin of water-induced nucleation growth kinetics enhancement, FT-IR and X-ray photoelectron spectroscopy (XPS) were conducted. As shown in Figure S7, a broad absorption peak at approximately 3,442 cm−1 and an additional peak at 1,672 cm−1 for PNCs with added ...
