The relative abundances of compound classes (e.g. CHO1, CHO2 and CHNO1) in fossil fuels have been widely used in previous researches based on the data from mass spectrometry (MS). However, such observations are susceptible to the ionization bias of MS due to the variation of ionization efficiency, which may affect the downstream quantitative analysis. Many efforts have been devoted to investigating the ionization efficiencies of a variety of model compounds, but not complex and diverse mixtures. Therefore, it is necessary to investigate how quantitatively ionization bias affects the MS analysis of complex mixtures. In this study, ionization bias was preliminarily investigated by comparing the elemental compositions obtained from MS-analysis via different ionization methods with the data acquired by a standard elemental analyzer. A coal-derived liquid and mixtures of five model compounds were ionized by atmospheric-pressure chemical ionization (APCI), electrospray ionization or direct analysis in real-time, followed by analyzing using a high-resolution Orbitrap MS to obtain elemental compositions. MS-based results via APCI ion source showed the closest elemental compositions to those obtained from the elemental analyzer. For the MS-based analysis, the abundances of S-and O-containing compounds were significantly lower and that of N-containing compounds was clearly higher compared to ultimate analysis. The abundances of compound classes were adjusted to provide a closer approximation of the actual contents, which might better serve for the downstream quantitative analysis. Although absolute quantification still needs additional work, the adjusted MS-based analysis provides not only the molecular level data, but also a better quantification ability compared to previous analytical approaches.

I found the field of Engineering; Environmental Sciences & Ecology very interesting. Saw the article Complex Mixtures of Brominated/Chlorinated Diphenyl Ethers and Dibenzofurans in Soils from the Agbogbloshie e-Waste Site (Ghana): Occurrence, Formation, and Exposure Implications published in 2019.0. HPLC of Formula: C12H10O, Reprint Addresses Kunisue, T (corresponding author), Ehime Univ, CMES, 2-5 Bunkyo Cho, Matsuyama, Ehime 7908577, Japan.. The CAS is 101-84-8. Through research, I have a further understanding and discovery of Diphenyl oxide

The distribution and toxic equivalents (TEQs) of brominated and chlorinated dibenzo-p-dioxins/dibenzofurans (PBDD/Fs and PCDD/Fs) in soils from Agbogbloshie e-waste site (Ghana) were investigated. The composition of brominated/chlorinated dibenzofurans (PXDFs) and diphenyl ethers (PBDEs, PCDEs, and PXDEs) was examined using two-dimensional gas chromatography time-of-flight mass spectrometry to elucidate possible formation pathways of dioxins from e-waste recycling. The highest concentrations of PCDD/Fs and PBDD/Fs were found, respectively, in the open burning (1.3-380 ng/g dry weight) and dismantling areas (11-1000 ng/g dry weight) and were comparable to the highest reported for informal e-waste sites. PXDFs and PXDEs were detected at up to the range of hundreds of nanograms per gram. The homologue profiles suggest that PXDFs were formed mainly from PBDFs through successive Br-to-Cl exchange. However, monobromo-PCDFs were also derived from de-novo-generated PCDFs in open burning areas. PBDFs contributed similar or higher TEQs (7.9-5400 pg/g dry weight) compared with PCDD/Fs (6.8-5200 pg/g dry weight), whereas PXDFs were also substantial TEQ contributors in open burning areas. The high TEQs of PBDFs in the dismantling area (120-5200 pg/g dry weight) indicate the need to consider brominated dioxins besides chlorinated dioxins in future studies on health implications for e-waste workers and local residents.

Single-atom catalysts are emerging as primary catalysts for many reactions due to their 100% utilization of active metal centers leading to high catalytic efficiencies. Herein, we report the use of a single-atom Co catalyst for the oxidative cleavage of the -O-4 bonds of lignin model compounds at a low oxygen pressure. Under the optimized reaction conditions, the conversion of 2-(2-methoxyphenoxy)-1-phenylethanol up to 95% with high selectivities was achieved with a variety of substrates investigated. The reusability of the Co catalyst with a high catalytic efficiency indicates its potential application in the oxidative cleavage of C-O bonds.

Thermal release of guest molecules from poly(2,6-dimethyl-1,4-phenylene)oxide (PPO) films, exhibiting host-guest cocrystalline (CC) phases with orientation of their chain axes being preferentially parallel or perpendicular to the film plane (c(parallel to) and c(perpendicular to) orientations), is studied. TGA analyses show that, for all the considered CC PPO films, temperatures of guest release for CC films with c(parallel to) orientation are definitely higher than those for CC films with c(perpendicular to) orientation, with differences even higher than 100 degrees C. Correspondingly, DSC scans of CC films with c(perpendicular to) orientation show separated endothermic peaks of guest release and melting, while CC films with c(parallel to) orientation only exhibit one broad endothermic peak with superimposed guest release, glass transition (T-g), and melting (T-m) phenomena. This control of temperatures of guest release could be helpful to maximize the thermal stability of host-guest PPO co-crystalline phases and to tailor temperatures of active guest release.

Atmospheric brown carbon (BrC) has recently attracted great concerns due to its potential contribution to climate change. It was reported that dissolved Fe(III) species can act as an efficient oxidant to catalyze the polymerization of volatile phenol substances, subsequently forming atmospheric BrC in aerosols. Since Fe in the atmosphere is commonly associated with clay mineral dusts, the transformation of phenol substances on Fe-bearing clay mineral surface is potentially important for BrC formation. In this study, taking guaiacol as the model phenol substance, its brown carbon formation process was investigated on Fe(III) modified montmorillonite under different relative humidities (RHs). The spectroscopic features and compositions of the produced BrC were systematically characterized. The results demonstrated that the interface FeOH2+ is the key species to promote the polymerization of guaiacol, and RH plays a significant role to influence the surface acidity of clay and the gas-to-particle adsorption of guaiacol. The BrC was produced with the most abundance and variety under moderate RH (similar to 33%), while higher RH (similar to 100%) accelerated the polymerization rate. Since aerosol moisture content might not largely influence the hydroxylation states of the surface bearing Fe(III) species, it signifies the importance of clay associated Fe(III) to catalyze the BrC formation in varied conditions Our study highlights the importance of clay mineral dust on the formation of BrC, and reveals the brown carbon formation pathways under environmentally relevant conditions.

In this study, the influence of grapefruit seed extract (GFSE) was studied on citric acid and zinc oxide incorporated cellulose-based hydrogel films. The effect of GFSE (0.25-1.0%, v/v) on hydrogel films was examined for their physico-chemical, mechanical, thermal, antioxidant and antibacterial properties. The swelling ratio, tensile strength and thermal stability of films decreased with increase in GFSE concentrations. On the other hand, elongation (%) and antioxidant activity of films were found to be 34-60% and 25-79%, respectively for increasing amounts of GFSE. FESEM and FETEM clearly showed that two different types of nanoparticles (50-90 nm and 5-10 nm) were present in GFSE incorporated films. The release of polyphenolic compounds and zinc from films was in sustained manner. Furthermore, the fabricated hydrogel films exhibited antibacterial activity against both E. coli and S. aureus. All these results indicate that the prepared nanocomposite hydrogel films could find their potential applications in wound healing.

The combination of materials with different magnetic properties at the nanoscale can lead to phenomena such as exchange bias via coupling effects, which shows huge potential for applications, e.g., in storage media or magnetic sensors. Whilst such structures so far are obtained via complex processes of alternating deposition from the gas phase hampering their application, their preparation from nanoparticle dispersions would not only be simplified but also enable a broad variety of possible material combinations and structures. Thereby, the processing of hard magnetic nanoparticles is challenging but can be circumvented by the use of precursor materials with subsequent phase transformation.

This paper studies the cooperative effect of Au nanoparticles deposited on vanadyl pyrophosphate oxide (VPO) in the liquid phase oxidation of benzyl alcohol. VPO was prepared using the classical method by thermally treating VOHPO4 center dot 0.5H(2)O precursor in reacting atmosphere at 420 degrees C for a period of 72 h. Au nanoparticles were deposited by incipient wetness method. The catalysts were characterized by means of XRD, TEM, XPS and Raman. The bulk VPO catalyst contains vanadyl pyrophosphate phase ((VO)(2)P2O7), and a small amount of VOPO4. The catalytic system exhibits a high activity in the base-free liquid phase oxidation of alcohols compared to Au on activated carbon, classic catalyst used for this type of reaction. Au/VPO showed a high peculiar selectivity to benzyl benzoate (76%), an important product used in the pharmaceutical and perfume industries. This behavior might be ascribed to the presence of strong acid sites of VPO, as determined by liquid phase titration. Stability tests performed on Au/VPO showed a deactivation of 10% after the first run, but a constant conversion along the following five cycles. This phenomenon can be attributed to the increase of mean Au particle size (from 19.1 to 23.4 nm) after recycling tests as well as the partial leaching of Au and V in the reaction media. Moreover, XRD evidenced a modification in the VPO structure with the partial formation of VOHPO4 center dot 0.5H(2)O phase.
