A practical method for the synthesis of phenyl enol ethers is reported. The combination of a gold(I) catalyst and potassium carbonate selectively mediates the addition of phenols to propargylic alcohols/amines in a chemo-, regio-, and stereoselective fashion in high yield. The resulting enol ethers are formed exclusively with a Z-configuration and can be obtained from a wide array of phenols and propargylic alcohols or amines with the reaction showing excellent functional group tolerance.

We investigated the photocatalytic performance of a magnetic nanohybrid of CoFe2O4 and TiO2 hetero-nanostructures (TiO2/CoFe2O4) conjugated with zinc tetrakis carboxyphenyl porphyrin (ZnTCPP) for controlled oxidation of alcohols to aldehydes under visible light. The photocatalyst was prepared by nucleating titania on pre-formed CoFe2O4 nanoparticles, generating anatase TiO2/CoFe2O4 hetero-nanostructures upon annealing at 450 degrees C. Then, they were conjugated with ZnTCPP resulting in ZnTCPP-TiO2/CoFe2O4 nanohybrid materials, which were characterized in detail by different structural and spectroscopic methods. The ZnTCPP-TiO2/CoFe2O4 nanostructures have an average size of 21 nm and show ferromagnetic behavior with a magnetization saturation of 47 emu g(-1), a remanence of 22 emu g(-1), and a coercivity of ca. 1000 Oe. The photocatalytic conversion of alcohols up to 87% under visible light was achieved by using this hybrid nanomaterial. Such a high catalytic performance can be related to the low charge recombination rate of the ZnTCPP-TiO2/CoFe2O4 nanostructures. The magnetic hybrid nanostructures reported in this work have excellent potential as visible light photocatalysts with advantages of high efficiency, selectivity, stability, and easy separation.

The quality of the Dniester River Basin has been seriously impacted by the chemicals released by agriculture, industry, and wastewater discharges. To assess its current chemical pollution status, a transboundary monitoring campaign was conducted in May 2019. Thirteen surface water, 13 sediment, and three biota samples were collected and analyzed using generic sample preparation methods for the determination of organic substances by liquid chromatography high-resolution mass spectrometry (LC-HRMS) and metals by inductively coupled plasma mass spectrometry (ICP-MS). Wide-scope target and suspect screening resulted in detection of Water Framework Directive (WFD) priority substances and emerging contaminants, whereas the raw data were stored in NORMAN Digital Sample Freezing Platform (DSFP) for future retrospective screening. Furthermore, risk assessment was performed to prioritize detected substances and propose a draft list of river basin-specific pollutants. All studied metals (As, Hg, Zn, Cu, Cr, Cd, Pb, Ni) were detected in the surface water and sediments. In total, 139 organic contaminants belonging to various chemical classes (pesticides, pharmaceuticals, drugs of abuse, stimulants, sweeteners, industrial chemicals, and their transformation products) were detected. The highest cumulative concentration of contaminants was observed in surface water from the Byk River, a tributary of the Dniester (Moldova). Concentrations of WFD priority substances diuron and mercury and EU Watch List neonicotinoid compounds imidacloprid and thiamethoxam exceeded their environmental quality standards (EQS), whereas concentrations of 23 emerging substances exceeded their predicted no-effect concentration (PNEC) at minimum one site. Emerging contaminants telmisartan, metolachlor, terbuthylazine, and 4-acetamidoantipyrine were prioritized as potential river basin-specific pollutants. Graphical abstract

Benzothiazole-tethered pyranopyrazoles derivatives were prepared via environmentally favorable conditions, which included eco-friendly catalyst, ethanol-water solvent, one-pot reaction, and atom- and step-economy procedures. Excellent yield of the products was observed. Besides, all products were screened for their antimicrobial behavior. From the biological results, it was seen that most of the compounds possessed high to moderate antimicrobial properties. Compound 6a gave prominent antimicrobial property followed by 6d, 6l, and 6n. In addition, computer-aided studies of the active compounds were also conducted. In this, selected compounds were docked into the intercalation site of DNA of the DNA-gyrase complex. From these results, the highest binding energy of -10.1 kcal/mol was for 6a against DNA-gyrase. This is the first eco-friendly synthetic method for the preparation of benzothiazole-pyranopyrazoles and the synthetic effort in this study may serve as a model for additional environmentally benign reactions. The biological results may prompt further studies related to antibiotic drugs.

A trade-off between enhancement of physical properties of the final part and the processability during manufacturing always exists for the application of nanocarbon materials in thermoset-based composites. For different epoxy resins, this study elaborates the impact of nanocarbon particle type, functionalization, and filler loading on the resulting properties, i.e., rheological, electrical, thermo-mechanical, as well as the fracture toughness in mode I and mode II loading. Therefore, a comprehensive set of carbon nanoparticles, consisting of carbon black (CB), single-walled carbon nanotubes (SWCNT), multi-walled carbon nanotubes (MWCNT), few layer graphene (FLG), and electrochemically expanded graphite (ExG), in purified or functionalized configuration was introduced in various epoxy resins, with different molecular weight distributions. A novel technique to introduce sharp cracks into single-edge notched bending (SENB) fracture toughness specimens led to true values. SWCNT show highest potential for increasing electrical properties without an increase in viscosity. Functionalized MWCNT and planar particles significantly increase the fracture toughness in mode I by a factor of two.

Lytic polysaccharide monooxygenases (LPMOs), a class of copper-dependent enzymes, play a crucial role in boosting the enzymatic decomposition of polysaccharides. Here, we reveal that LPMOs might be associated with a lignin degradation pathway. An LPMO from white-rot fungus Pleurotus ostreatus, LPMO9A (PoLPMO9A), was shown to be able to efficiently drive the activity of class II lignin-degrading peroxidases in vitro through H2O2 production regardless of the presence or absence of a cellulose substrate. An LPMO-driven peroxidase reaction can degrade beta-O-4 and 5-5′ types of lignin dimer with 46.5% and 37.7% degradation, respectively, as well as alter the structure of natural lignin and kraft lignin. H2O2 generated by PoLPMO9A was preferentially utilized for the peroxidase from Physisporinus sp. strain P18 (PsVP) reaction rather than cellulose oxidation, indicating that white-rot fungi may have a strategy for preferential degradation of resistant lignin. This discovery shows that LPMOs may be involved in lignin oxidation as auxiliary enzymes of lignin-degrading peroxidases during the white-rot fungal decay process. IMPORTANCE The enzymatic biodegradation of structural polysaccharides is affected by the degree of delignification of lignocellulose during the white-rot fungal decay process. The lignin matrix decreases accessibility to the substrates for LPMOs. H2O2 has been studied as a cosubstrate for LPMOs, but the formation and utilization of H2O2 in the reactions still represent an intriguing focus of current research. Lignin-degrading peroxidases and LPMOs usually coexist during fungal decay, and therefore, the relationship between H2O2-dependent lignin-degrading peroxidases and LPMOs should be considered during the wood decay process. The current study revealed that white-rot fungal LPMOs may be involved in the degradation of lignin through driving a versatile form of peroxidase activity in vitro and that H2O2 generated by PoLPMO9A was preferentially used for lignin oxidation by lignin-degrading peroxidase (PsVP). These findings reveal a potential relationship between LPMOs and lignin degradation, which will be of great significance for further understanding the contribution of LPMOs to the white-rot fungal decay process.

The aim of this study was to develop a bioprocess for low temperature fruit wine making from ready-to-use freeze-dried raw materials: sour cherry (Prunus cerasus) juice and the psychrotolerant and alcohol resistant yeast strain Saccharomyces cerevisiae AXAZ -1 immobilized on porous delignified cellulose. The effect of storage time of the freeze-dried raw materials at 4 degrees C (0, 30, and 60 days) on the fermentation efficiency of the yeast, as well as on the quality of the produced wines was evaluated. Sweet wines (>14% v/v alcohol) were produced without need for extra commercial alcohol addition. The sweet, sour cherry wines produced at 10 degrees C using the freeze-dried raw materials, were analyzed for their aroma profile by headspace SPME GC-MS analysis as well as for their sensory attributes. All wines had similar aroma characteristics with fresh and fruity (cherry) notes, and high esters content. The fermentation kinetics and the sensory characteristics indicate the potential of the freeze-dried raw materials as a ready-to-use mixture for good quality sour cherry sweet wine making even at low temperatures.
