Braguglia, C. M. published the artcileQuality assessment of digested sludges produced by advanced stabilization processes, Recommanded Product: N-Benzyl-N,N-dibutylbutan-1-aminium chloride, the publication is Environmental Science and Pollution Research (2015), 22(10), 7216-7235, database is CAplus and MEDLINE.

The European Union (EU) Project Routes aimed to discover new routes in sludge stabilization treatments leading to high-quality digested sludge, suitable for land application. In order to investigate the impact of different enhanced sludge stabilization processes such as (a) thermophilic digestion integrated with thermal hydrolysis pretreatment (TT), (b) sonication before mesophilic/thermophilic digestion (UMT), and (c) sequential anaerobic/aerobic digestion (AA) on digested sludge quality, a broad class of conventional and emerging organic micropollutants as well as ecotoxicity was analyzed, extending the assessment beyond the parameters typically considered (i.e., stability index and heavy metals). The stability index was improved by adding aerobic posttreatment or by operating dual-stage process but not by pretreatment integration. Filterability was worsened by thermophilic digestion, either alone (TT) or coupled with mesophilic digestion (UMT). The concentrations of heavy metals, present in ranking order Zn > Cu > Pb > Cr ∼ Ni > Cd > Hg, were always below the current legal requirements for use on land and were not removed during the processes. Removals of conventional and emerging organic pollutants were greatly enhanced by performing double-stage digestion (UMT and AA treatment) compared to a single-stage process as TT; the same trend was found as regards toxicity reduction Overall, all the digested sludges exhibited toxicity to the soil bacterium Arthrobacter globiformis at concentrations about factor 100 higher than the usual application rate of sludge to soil in Europe. For earthworms, a safety margin of factor 30 was generally achieved for all the digested samples.

Pai, Zinaida P. published the artcileTungsten Peroxopolyoxo Complexes as Advanced Catalysts for the Oxidation of Organic Compounds with Hydrogen Peroxide, Product Details of C19H34ClN, the publication is Applied Catalysis, A: General (2020), 117786, database is CAplus.

Selective oxidation of organic substrates by environment-friendly oxidizing agents is an important ingredient of the sustainable chem. industry. Here we report a comprehensive study in the field of metal peoroxocomplex catalysis for the selective liquid phase oxidation of various organic substrates. A number of well-defined bi-functional tungsten complex catalysts with tetra nuclear structure {PO4[WO(O₂)₂]₄}^3- in combination with a phase-transfer agents were synthesized. The structural properties were thoroughly studied using of IR, Raman and EXAFS spectroscopy. By combining different spectroscopy techniques were able to elucidate the effect of quaternary ammonium cations on the structural properties of the resulting peroxo complexes. The catalytic properties of these well-defined material were then evaluated in bi-phasic selective oxidation of cyclooctene, Me oleate and N-phosphonomethyliminodiacetic acid with hydrogen peroxide under mild conditions. For every substrate we were able to achieve high conversion at the selectivity towards a target product close to 100%.

Arakawa, Yukihiro published the artcileAsymmetric transfer hydrogenation of aromatic ketones in water using a polymer-supported chiral catalyst containing a hydrophilic pendant group, Computed Properties of 23616-79-7, the publication is Advanced Synthesis & Catalysis (2008), 350(14+15), 2295-2304, database is CAplus.

Hydrophilic polymers having pendant groups of carboxylates or sulfonates have been used as a polymer support for chiral 1,2-diamine monosulfonamides. The polymeric chiral complex prepared from the polymer-supported chiral ligand with ruthenium dichloride p-cymene was used in the asym. transfer hydrogenation of prochiral ketones in water. The balance between hydrophilicity and hydrophobicity of the polymer support influenced both the reactivity and the enantioselectivity of the reaction in water. The chiral polymeric complex having a quaternary ammonium salt structure as the pendant group worked well in water. In most cases the polymer-supported catalyst having a quaternary ammonium sulfonate pendant group showed superior enantioselectivity compared to the corresponding nonsupported model catalyst in the solution system. The polymeric catalysts can be reused without loss of catalytic activity.

Baj, Stefan published the artcileNew and efficient technique for the synthesis of ε-caprolactone using KHSO₅ as an oxidizing agent in the presence of a phase transfer catalyst, Quality Control of 23616-79-7, the publication is Applied Catalysis, A: General (2011), 395(1-2), 49-52, database is CAplus.

A new method for the synthesis of ε-caprolactone based on the Baeyer-Villiger oxidation of cyclohexanone was developed. In the proposed reaction, potassium peroxomonosulfate was used as an oxidizing agent under phase transfer catalysis conditions. The effects of the reaction parameters, including the type of phase transfer catalyst, the concentration of the oxidizing agent, the type of organic solvent and temperature, were investigated. When dichloromethane was used as an organic solvent and an adequate amount of water was added to the reaction mixture, the highest yield and selectivity for ε-caprolactone were achieved at 40°.

Elimination of amyloid-β (Aβ) oligomers remains challenging. We describe here a novel strategy to prevent and eliminate the Aβ oligomers from either the early aggregation or the fibril dissolution pathway by targeting the flexible N-terminus, but not the widely investigated hydrophobic segment, with a rationally designed cyclopeptide.

A subphthalocyanine-dithienylethene dyad has been synthesized and characterized by ¹H-, ¹³C-NMR, HR-MS, UV-visible and emission spectroscopy. The results show that photoinduced isomerization of dithienylethene moiety from close-form to opened form can be achieved under visible light using subphthalocyanine as a light-harvesting unit and the fluorescence properties of subphthalocyanine could be modulated by the isomerization state of the dithienylethene moiety.

Morant-Giner, Marc published the artcileFunctionalisation of MoS₂ 2D layers with diarylethene molecules, COA of Formula: C15H14Cl2S2, the publication is Journal of Materials Chemistry C: Materials for Optical and Electronic Devices (2021), 9(33), 10975-10984, database is CAplus.

Functionalisation of two-dimensional (2D) materials with stimuli-responsive mols. has been scarcely investigated. Here, MoS₂ layers obtained by chem. exfoliation are covalently and non-covalently functionalised using two photoswitchable diarylethene derivatives under their open- and closed-ring isomers. The choice of these light-responsive mols. is based on their excellent thermal irreversibility and fatigue resistance. The characterization of the resultant mol./2D heterostructures proves the successful anchoring of the mols. by both approaches as well as the influence that the driving interaction has on the photoswitching behavior of the diarylethene isomers after their deposition on the 2D layer.

Boyer, John-Christopher published the artcilePhotomodulation of Fluorescent Upconverting Nanoparticle Markers in Live Organisms by Using Molecular Switches, Computed Properties of 219537-97-0, the publication is Chemistry – A European Journal (2012), 18(11), 3122-3126, S3122/1-S3122/17, database is CAplus and MEDLINE.

It is successfully demonstrated that the ability to modulate the luminescence from upconverting nanoparticles in vitro and in vivo by taking advantage of the well-understood photochem. of DTE mol. switches decorated onto nanoparticle surfaces by the use of CuACC chem. By reversibly converting the photoswitch back and forth between the two isomers by using UV and visible light, we are able to toggle the system between on (bright fluorescence) and off (quenched fluorescence) states. This process can be cycled multiple times before any degradation of the nanoparticles or the photo-switch renders the system impractical. The system has an advantage over ‘caged’ fluorophores as the luminescence of our designed nanoparticles can be repeatedly cycled through on and off states. Systems such as the one described not only have the capacity to reversibly control the intensity of the probe emission, through selective absorption, they can also alter the color of the emitted light from multicolored probes; this further enhances the imaging capabilities.

Warford, C. Chad published the artcileFrom slow to fast – the user controls the rate of the release of molecules from masked forms using a photoswitch and different types of light, Application In Synthesis of 219537-97-0, the publication is Chemical Communications (Cambridge, United Kingdom) (2015), 51(32), 7039-7042, database is CAplus and MEDLINE.

Exposure to UV light generates a ring-closed isomer of a diarylethene, which undergoes very slow bond breaking and release even after the light is turned off. The rate of release is increased by exposing the isomer to UV and/or visible light.
