A novel and rapid approach to characterise the occurrence of contaminants of emerging concern (CECs) in river water is presented using multi-residue targeted analysis and machine learning-assisted in silico suspect screening of passive sampler extracts. Passive samplers (Chemcatcher (R)) configured with hydrophilic-lipophilic balanced (HLB) sorbents were deployed in the Central London region of the tidal River Thames (UK) catchment in winter and summer campaigns in 2018 and 2019. Extracts were analysed by; (a) a rapid 5.5 min direct injection targeted liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for 164 CECs and (b) a full-scan LC coupled to quadrupole time of flight mass spectrometry (QTOF-MS) method using data-independent acquisition over 15 min. From targeted analysis of grab water samples, a total of 33 pharmaceuticals, illicit drugs, drug metabolites, personal care products and pesticides (including several EU Watch-List chemicals) were identified, and mean concentrations determined at 40 +/- 37 ng L-1. For targeted analysis of passive sampler extracts, 65 unique compounds were detected with differences observed between summer and winter campaigns. For suspect screening, 59 additional compounds were shortlisted based on mass spectral database matching, followed by machine learning-assisted retention time prediction. Many of these included additional pharmaceuticals and pesticides, but also new metabolites and industrial chemicals. The novelty in this approach lies in the convenience of using passive samplers together with machine learning-assisted chemical analysis methods for rapid, time-integrated catchment monitoring of CECs.

We have examined enantioselective bioreduction of acetophenone and its substituted derivatives into corresponding S-alcohols catalyzed by Daucus carota and Petroselinum crispum plant cells in water and isooctane. We found that the nature of the substituent has a profound effect on the relative reactivity of substituted acetophenones and enantioselectivity of biocatalytic reduction. Electron-withdrawing substituents -Br and -NO2 enhance the initial rate of reaction and yields of products, while electron donating substituent -OCH3 decreases them. The reduction rates and yields of products in water were noticeably higher in comparison with similar reductions conducted in isooctane. Correlations between the initial reaction rate and the substituent constant (sigma(+)) in the aromatic ring characterizing its nature were established. Comparison of rho constants of bioreduction catalyzed by D. carota and P. crispum shows that the sensitivity of the reduction to the nature of the substituents is more significant in the case of D. carota biocatalyst. Comparison of rho constants for D. carota and P. crispum in water and isooctane indicates that the sensitivity of bioreduction to the nature of the substituent tends to increase from water to isooctane.

The present work describes the crystal structure, third-order nonlinear optical (NLO) properties and Hirshfeld Surface (HFs) analysis of 1-(4-nitrophenyl)-3-(2, 3, 4,-trimethoxyphenyl) prop-en-1-one (2, 3,4TMNC). The synthesized material was characterised by FT-IR, FT-Raman, UV-Visible, NMR [H-1, C-13 {H-1}] and single crystal X-ray diffraction techniques. TGA-DTA analysis revealed that crystal has higher thermal stability. HFs analysis is performed to visualize intra and intermolecular interactions (C-H center dot center dot center dot O). The third-order NLO properties were studied using standard open and closed aperture Z-Scan technique with a continuous wave (CW) DPSS laser (lambda= 532 nm). The calculated values of nonlinear refraction coefficient (n(2)), third-order nonlinear susceptibility (chi((3))) and nonlinear absorption coefficient ((3) were found to be of the order of -10(-9) cm(2)/W, 10(-7) esu and 10(-5) cmW(-1) respectively. Normalized transmittance is decreased with increased input intensity of laser i.e. 2, 3, 4 TMNC showed good optical limiting property. The optical limiting threshold was found to be 3.36 kJ/cm(2). Thus, the title chalcone derivative is a potential material for optical limiting applications. (C) 2019 Elsevier B.V. All rights reserved.

In attempt to take advantages of naturally occurring compounds for the catalysis, a novel composite composed of beta-cyclodextrin, dendrimer and bentonite clay is fabricated and utilized as a support for the stabilization of Pd nanoparticles. To prepare the support, bentonite is amino functionalized and then successively reacted with 2,4,6-trichloro-1,3,5-triazine and ethylenediamine to furnish a dendrimer of generation II on bentonite. Afterwards, the terminal functionalities of the dendrimer were adorned with cyclodextrin. Bentonite played role in the hetemgenation of the catalyst and improvement of the stability of the composite while, cyclodextrins served as molecular shuttles and capping agent for the as-prepared Pd nanoparticles. Dendrimer with multi nitrogen atoms, on the other hand, improved Pd anchoring through electrostatic interactions. The catalyst was applied for the hydrogenation of nitmarenes under mild reaction condition in aqueous media in a selective manner. Notably, the catalyst could be recovered and reused repeatedly.

A brick pavement, tramped by humans, is exposed to atmospheric elements, thus allowing cyanobacteria and algae to colonise. In this article, we report on the factors that contribute to the slipperiness of a brick pavement at the University of Venda in the Limpopo province of the South Africa. Samples were collected from brick surfaces either colonised by green algae (treated) or not (control). The samples were acid-digested and analysed for metals by Inductively Coupled Plasma Mass Spectrometry (ICP MS) in parts per billion (ppb). The treated bricks, with green algae, had average high metal contents (ppb): Al 9456.02, Ti 731.23, V 46.44, Cr 78.85, Mn 862.93, Fe 16295.18, Co 23.57, Ni 59.36, Cu 66.31, Zn 160.57, As 7.92, Se 10.45, Mo 6.74, Cd 5.19, Sn 4.65, Sb 2.31 and Pb 19.51. In contrast, control bricks had a low average of metal content (ppb) as follows: Al 2.99, Ti 0.28, V 4.04, Cr 1.42, Mn 4.29, Fe 20.89, Co 0.36, Ni 2.74, Cu 5.64, Zn 4.21, As 0.56, Se <3.00, Mo 0.88, Cd 0.01, Sn 1.05, Sb 0.04 and Pb 0.04. Other factors that promote algae colonisation include high solar radiation, neutral pH, nutrients, low electrical conductivity and total dissolved solids. The algae colonisation of brick pavement results in an unaesthetic sighting and a slippery surface that is hazardous to humans. Quality Control of 2,2-Diphenylacetonitrile.

Described is a physical organic study of the reduction of three sets of carbonyl compounds by the NADPH-dependent enzyme Clostridium acetobutylicum alcohol dehydrogenase (CaADH). Previous studies in our group have shown this enzyme to display broad substrate promiscuity, yet remarkable stereochemical fidelity, in the reduction of carbonyl compounds, including alpha-, beta- and gamma-keto esters ( d -stereochemistry), as well as alpha,alpha-difluorinated-beta-keto phosphonate esters ( l -stereochemistry). To better mechanistically characterize this promising dehydrogenase enzyme, we report here the results of a Hammett linear free-energy relationship (LFER) study across three distinct classes of carbonyl substrates; namely aryl aldehydes, aryl beta-keto esters and aryl trifluoromethyl ketones. Rates are measured by monitoring the decrease in NADPH fluorescence at 460 nm with time across a range of substrate concentrations for each member of each carbonyl compound class. The resulting v (0) versus [S] data are subjected to least-squares hyperbolic fitting to the Michaelis-Menton equation. Hammett plots of log( V (max) ) versus sigma (X) yield the following Hammett parameters: (i) for p -substituted aldehydes, rho = 0.99 +/- 0.10, rho = 0.40 +/- 0.09; two domains observed, (ii) for p -substituted beta-keto esters rho = 1.02 +/- 0.31, and (iii) for p -substituted aryl trifluoromethyl ketones rho = -0.97 +/- 0.12. The positive sign of rho indicated for the first two compound classes suggests that the hydride transfer from the nicotinamide cofactor is at least partially rate-limiting, whereas the negative sign of rho for the aryl trifluoromethyl ketone class suggests that dehydration of the ketone hydrate may be rate-limiting for this compound class. Consistent with this notion, examination of the (13) C NMR spectra for the set of p -substituted aryl trifluo-romethyl ketones in 2% aqueous DMSO reveals significant formation of the hydrate ( gem -diol) for this compound family, with compounds bearing the more electron-withdrawing groups showing greater degrees of hydration. This work also presents the first examples of the CaADH-mediated reduction of aryl trifluoromethyl ketones, and chiral HPLC analysis indicates that the parent compound alpha,alpha,alpha-trifluoroacetophenone is enzymatically reduced in 99% ee and 95% yield, providing the ( S )-stereoisomer, suggesting yet another compound class for which this enzyme displays high enantioselectivity.
