Physico-chemical characterization of sterilized CeO2 nanoparticles by XPS / HAXPES / SEM

Here a dataset of XPS, HAXPES and SEM measurements for the physico-chemical characterization of sterilized nanoparticles is presented. The measurements are part of the H2020 project “NanoSolveIT”. CeO2 nanoparticles were provided by Promethean Particles and treated differently by project partners from the University of Birmingham (EMR identifier in the project: ERM00000398, ERM00000440, ERM00000419). The particles were treated by different sterilization methods (autoclave or microwave) and BSA was or was not added as stabilizer. This finally leads to five different samples: pristine, autoclave, microwave, autoclave with BSA, microwave with BSA. Prior to the measurements, the samples were prepared from the solution as drop cast on Si wafers.  First SEM and EDS measurements were performed, followed by XPS and HAXPES measurements on the same samples. Here at first survey spectra were recorded followed by high resolution spectra. For XPS / HAXPES several Si-wafers were mounted together on one platen. The platen was left in the intro chamber of the instrument for several hours before the measurement started. Equipment: SEM images were acquired with a Supra 40 (Zeiss) SEM equipped with a Quantax 400 (Bruker) SDD EDS spectrometer. For X-ray spectroscopy experiments, a combined XPS / HAXPES spectrometer (Quantes from ULVAC-PHI) was used, where XPS is measured at 1486.6 eV (monochromatic Al Kα source) and HAXPES at 5414.9 eV (monochromatic Cr Kα source). Here it is possible to perform the measurements at the exact same position. Data: For SEM, the data are given in .tif format. For XPS / HAXPES the raw data are given as .spe (PHI format) and .npl (VAMAS format) files. The measurement conditions are given in the data files. Naming of data: SEM: sample_treatment (n), with n a consecutive number. XPS / HAXPES:   For the .spe files Pn.m.o.sample_treatment and for the corresponding .npl files: m.npl with Pn: platen-number, m: spectrum number (order of the measurements); o: point-number, of the position on the sample, sample_treatment with "m" for microwave and "a" for autoclave.

Chemical characterization of PM2.5 and source apportionment of organic aerosol in New Delhi, India

Delhi is one of the most polluted cities worldwide and a comprehensive understanding and deeper insight into the air pollution and its sources is of high importance. We report 5 months of highly time-resolved measurements ofnon-refractory PM2.5 and black carbon (BC). Additionally, source apportionment based on positive matrix factorization (PMF) of the organic aerosol (OA) fraction is presented. The highest pollution levels are observed during winter in December/January. During that time, also uniquely high chloride concentrations are measured, which are sometimes even themost dominant NR-species in themorning hours. With increasing temperature, the total PM2.5 concentration decreases steadily, whereas the chloride concentrations decrease sharply. The concentrationsmeasured in May are roughly 6 times lower than in December/January. PMFanalysis resolves two primary factors, namely hydrocarbon-like (traffic-related) OA (HOA) and solid fuel combustion OA (SFCOA), and one or two secondary factors depending on the season. The uncertainties of the PMF analysis are assessed by combining the random a-value approach and the bootstrap resampling technique of the PMF input. The uncertainties for the resolved factors range from ±18% to ±19% for HOA, ±7% to ±19% for SFC-OA and ±6 % to ±11% for the OOAs. The average correlation of HOA with equivalent black carbon from traffic (eBCtr)is R2 = 0.40, while SFC-OA has a correlation of R2 = 0.78 with equivalent black carbon from solid fuel combustion (eBCsf). Anthracene (m/z 178) and pyrene (m/z 202) (PAHs) are mostly explained by SFC-OA and follow its diurnal trend (R2=0.98 and R2=0.97). The secondary oxygenated aerosols are dominant during daytime. The average contribution during the afternoon hours (1 pm–5 pm) is 59% to the total OA mass, with contributions up to 96% in May. In contrast, the primary sources are more important during nighttime: the mean nightly contribution (22 pm–3 am) to the total OA mass is 48%, with contributions up to 88% during some episodes in April.   This repository contains the data corresponding to the figures presented in the published main text.
