Sulfonic Acid-Functionalized Silica-Coated Magnetic Nanoparticles as a Reusable Catalyst for the Preparation of Pyrrolidinone Derivatives Under Eco-Friendly Conditions

The surface of silica-coated CoFe2O4 magnetic nanoparticles (CoFe2O4@SiO2), which is resistant to the oxidation due to silicone coating, was functionalized using chlorosulfonic acid and used as an efficient and recyclable catalyst for the preparation of 3-pyrrolin-2-ones from diethyl acetylenedicarboxylate, an aldehyde and aniline in ethanol solvent at 60 degrees C. In the presented study, some fascinating chracteritics of such catalyst, such as magnetically separable, simple workup and obtaining a high purity of products by simple recrystallization, have been successfully obtained. The structural features of CoFe2O4@SiO2-SO3H catalyst were elucidated by X-ray powder diffraction (XRPD), thermo-gravimetric studying (TGA), scanning electron microscopy (SEM) and FT-IR spectra.

Effect of Particle Wettability and Particle Concentration on the Enzymatic Dehydration of n-Octanaloxime in Pickering Emulsions

Pickering emulsion systems have emerged as platforms for the synthesis of organic molecules in biphasic biocatalysis. Herein, the catalytic performance was evaluated for biotransformation using whole cells exemplified for the dehydration of n-octanaloxime to n-octanenitrile catalysed by an aldoxime dehydratase (OxdB) overexpressed in E. coli. This study was carried out in Pickering emulsions stabilised solely with silica particles of different hydrophobicity. We correlate, for the first time, the properties of the emulsions with the conversion of the reaction, thus gaining an insight into the impact of the particle wettability and particle concentration. When comparing two emulsions of different type with similar stability and droplet diameter, the oil-in-water (o/w) system displayed a higher conversion than the water-in-oil (w/o) system, despite the conversion in both cases being higher than that in a classic two-phase system. Furthermore, an increase in particle concentration prior to emulsification resulted in an increase of the interfacial area and hence a higher conversion.

Mapping Io’s Surface Composition With Juno/JIRAM

The surface composition of Io is dominated by SO2 frost, plus other chemical species identified or proposed over the past decades by combining Earth-based and space-based observations with laboratory data. Here we discuss spectroscopic data sets of Io obtained by the Jovian InfraRed Auroral Mapper (JIRAM) spectro-imager onboard Juno in nine orbits, spanning a 3-year period. We display average spectral profiles of Io in the 2-5 mu m range, and we use band depths derived from those profiles to map the geographic distribution of SO2 frost and other spectral features. This data set allows for an similar to 22% surface coverage at 58 to 162 km/px and in a broad range of latitudes. Our results confirm the broadly regional SO2-frost trends already highlighted by Galileo/NIMS. Io’s average spectral profiles as well as the mapping of the 4.47-mu m band also confirm that SO2 exists in the (SOO)-S-32-O-16-O-18 isotopic form. Surprisingly, the mapping performed by JIRAM shows that the absorption band at 2.1 mu m is unrelated to SO2 frost, while we map for the first time the depth of the 2.65-mu m band, highlighting regions enriched in this absorber, possibly H2S. JIRAM data confirm that the 3.92-mu m band, likely due to Cl2SO2, is largely related to the SO2 distribution. The correlation between Cl2SO2 and ClSO2, possibly revealed at 4.62 mu m, is not equally clear. The simultaneous presence of two very weak spectral features at 4.55 and 4.62 mu m suggests that nitrile compounds or tholins may also be present on the surface. Plain Language Summary The surface of Io is mainly covered by sulfur dioxide (SO2) frost and by other chemical species. The Jovian InfraRed Auroral Mapper (JIRAM) instrument onboard the NASA Juno spacecraft, in orbit around Jupiter, can occasionally observe the Galilean satellites through its slit spectrometer (2-5 mu m range). We show average spectral profiles of Io obtained by JIRAM in a 3-year period, mapping the geographic distribution of SO2 frost and other spectral features. Our results confirm the broadly regional SO2-frost trends already highlighted in the past. Our data confirm that SO2 exists in multiple isotopic forms. Surprisingly, the mapping performed by JIRAM shows that the absorption band at 2.1 mu m is unrelated to SO2 frost. We map for the first time the depth of the 2.65-mu m band, which might be related to hydrogen sulfide (H2S). We also highlight regions enriched in this absorber. We confirm that the 3.92-mu m band, ascribed to sulfuryl chloride (Cl2SO2), is largely correlated with the SO2 distribution. The correlation between Cl2SO2 and ClSO2, possibly revealed at 4.62 mu m, is not equally clear. The simultaneous presence of two very weak spectral features at 4.55 and 4.62 mu m suggests that nitrile compounds or tholins may also be present on the surface.
