Visual detection of p-toluenesulfonic acid (pTSA) is very important due to its health-harmful effects, but remains less investigated. In this study, a TGM (Triethylene Glycol Monomethyl ether) derived calix [4] carbazole was found to be able to selectively encapsulate pTSA by its cone conformation, thus specifically detecting it visually. To the best of our knowledge, it is the first case of pTSA visual detection based on host-guest binding triggered charge transfer. ? 2021 Elsevier B.V. All rights reserved.

With the growing concern about safety and environmental issues, amino acid-based surfactants have great potential as sustainable and eco-friendly substances. In the present study, six N-acyl oligopeptide surfactants were synthesized using fatty acid methyl esters (i.e., methyl caprate, methyl laurate, and methyl myristate) and glycyl oligopeptides (i.e., glycylglycine and glycylglycylglycine). Surface active properties and aggregation behaviors of these surfactants were investigated using surface tension, fluorescence probe, dynamic light scattering, and microscopy measurements. The adsorption at the air-water interface and aggregation in the aqueous solution depend on the structure of both hydrophilic head-groups and hydrophobic tails. Spherical vesicles were observed in the aqueous solutions of glycylglycine derivatives, whereas short tubular aggregates were found in that of corresponding glycylglycylglycine products. Intermolecular hydrogen-bonding interaction between the amide head-groups might be responsible for the different self-assembly behavior and microstructure of N-acyl oligopeptide surfactants in the aqueous solution.

Objective: To explore the relationship between meteorological factors and scarlet fever incidence from 2006 to 2017 in Guangzhou, the largest subtropical city of Southern China, and assist public health prevention and control measures. Methods: Data for weekly scarlet fever incidence and meteorological variables from 2006 to 2017 in Guangzhou were collected from the National Notifiable Disease Report System (NNDRS) and the Guangzhou Meteorological Bureau (GZMB). Distributed lag nonlinear models (DLNMs) were conducted to estimate the effect of meteorological factors on weekly scarlet fever incidence in Guangzhou. Results: We observed nonlinear effects of temperature, relative humidity, and wind velocity. The risk was the highest when the weekly mean temperature was 31 degrees C during lag week 14, yielding a relative risk (RR) of 1.48 (95% CI: 1.01-2.17). When relative humidity was 43.5% during lag week 0, the RR was 1.49 (95% CI: 1.04-2.12); the highest RR (1.55, 95% CI: 1.20-1.99) was reached when relative humidity was 93.5% during lag week 20. When wind velocity was 4.4 m/s during lag week 13, the RR was highest at 3.41 (95% CI: 1.57-7.44). Positive correlations were observed among weekly temperature ranges and atmospheric pressure with scarlet fever incidence, while a negative correlation was detected with aggregate rainfall. The cumulative extreme effect of meteorological variables on scarlet fever incidence was statistically significant, except for the high effect of wind velocity. Conclusion: Weekly mean temperature, relative humidity, and wind velocity had double-trough effects on scarlet fever incidence; high weekly temperature range, high atmospheric pressure, and low aggregate rain fall were risk factors for scarlet fever morbidity. Our findings provided preliminary, but fundamental, information that may be useful for a better understanding of epidemic trends of scarlet fever and for developing an early warning system. Laboratory surveillance for scarlet fever should be strengthened in the future. (C) 2019 Elsevier B.V. All rights reserved.

The migration of photoinitiators, phthalates and plasticizers from two paper and cardboard materials into food simulants (50% and 95% EtOH and Tenax) and foodstuffs (rice, cereals and milk powder) was studied. In the case of liquid simulants migration was observed to reach the equilibrium after 60 min and depended on the material type and the physicochemical parameters of the migrants, whereas the temperature (room temperature and 60 degrees C) did not show significant effects. The study of migration of the compounds from a baking paper to Tenax at high temperatures (150 and 250 degrees C) evidenced an increment of migration when increasing temperature, except for the most volatile analytes. Finally, the migration to foodstuffs was studied using fully validated analytical protocols. Overall, the comparison of the migration rates demonstrated that Tenax was adequate for the simulation of the migration to rice and cereals, but underestimated the migration to infant milk powder, for which 95% EtOH resulted a more suitable simulant.

MgO has been shown to catalyze an almost quantitative hydrogen transfer from 2-octanol as the hydrogen donor to benzophenone to form benzhydrol, a useful intermediate product in the pharmaceutical industry. The hydrogen transfer from a series of alcohols to the carbonyl group of benzophenone, its ten derivatives, four polycyclic ketones, and 2-naphthyl phenyl ketone was carried out in liquid (LP) or vapor phase (VP). The dependence of reactivity on the structure of the hydrogen donor, reaction temperature, donor-acceptor ratio, amount of catalyst, and the type and position of substituents has been established. For both reaction modes, optimal conditions for selective synthesis of the alcohols were determined and side reactions were investigated. The results indicate that the reactivity of the ketone is suppressed by the presence of a methyl substituent in the ortho position to a much greater extent in LP mode. A scale-up was demonstrated in the liquid phase mode.

The Name is Anthrone. Through research, I have a further understanding and discovery of 90-44-8.

Ball milling of calcium carbide (CaC2) enables the reaction of its ethynyl moiety with organic electrophiles. This was realized simply by co-milling CaC(2)with organic substrates in a sealed jar without the need for an additive or a catalyst. Various ketones including those bearing alpha-hydrogens were ethynylated in good yields at short reaction times. Aryl halides are also amenable substrates for this protocol as they furnish aryl ethynes through a benzyne intermediate. This method offers a practical and cheap alternative to the established procedures for introducing ethynyl functionalities.

Nitrogen-doped Graphene Quantum Dots (N-GQDs) is a significant carbon nanomaterial that can be used to design various metal-organocatalyst. Modification of N-GQDs plays a serious role in catalytic activity, recyclability, thermal stability, and so on. Also, finding revealed that homogeneity, morphology, and size of nanocomposites can be intensively influenced via various procedures and precursors. Hence, CuO/ZnO hexagonal nanocomposites with morphological engineering have been prepared by the hydrothermal method for improving performance. On the other hand, the study of the effect of amino acid as a chiral organic group on the surface of modified N-GQDs is essential for expanding new inorganic-organic hybrid catalysts. In this work, we introduced L-proline assisted CuO/ZnO@N-GQDs hexagonal nanocomposites as a robust recyclable nanocatalyst in multicomponent reactions (MCRs) for the preparation of 2-amino-4H-chromenes. As-prepared CuO/ZnO@N-GQDs@Lproline nanocatalyst has been investigated by High-resolution Transmission electron microscope (HRTEM), Transmission electron microscope (TEM), Field emission scanning electron microscopy (FE-SEM), BrunauerEmmett-Teller (BET), Energy-dispersive X-ray spectroscopy (EDS), Fourier transform infrared spectroscopy (FT-IR), Thermogravimetric analysis (TGA), and X-ray diffraction analysis (XRD). High atom economy (95%), recyclability catalyst (8 runs), avoided the utilization of further reagents such as additives, and excellent yield of products (80-94%) are a few vital highlights of this method.

The oxidative cleavage of C = C double bonds with molecular oxygen to produce carbonyl compounds is an important transformation in chemical and pharmaceutical synthesis. In nature, enzymes containing the first-row transition metals, particularly heme and non-heme iron-dependent enzymes, readily activate O-2 and oxidatively cleave C = C bonds with exquisite precision under ambient conditions. The reaction remains challenging for synthetic chemists, however. There are only a small number of known synthetic metal catalysts that allow for the oxidative cleavage of alkenes at an atmospheric pressure of O-2, with very few known to catalyze the cleavage of nonactivated alkenes. In this work, we describe a light-driven, Mn-catalyzed protocol for the selective oxidation of alkenes to carbonyls under 1 atm of O-2. For the first time, aromatic as well as various nonactivated aliphatic alkenes could be oxidized to afford ketones and aldehydes under clean, mild conditions with a first row, biorelevant metal catalyst. Moreover, the protocol shows a very good functional group tolerance. Mechanistic investigation suggests that Mn-oxo species, including an asymmetric, mixed-valent bis(mu-oxo)-Mn(III,IV) complex, are involved in the oxidation, and the solvent methanol participates in O-2 activation that leads to the formation of the oxo species.
