Thiol-functionalized PIM-1 for removal and sensing for mercury (II)

Polymers of intrinsic microporosity (PIMs) are a class of microporous polymers with rigid and contorted molecular structures. The special structures lead to incomplete space occupation, and the pores of PIMs originate from the formed void. In this work, we made attempts to expand the applications of PIMs to the aspect of heavy metal removal. First, PIM-1 was synthesized using tetrafluoroterephthalonitrile (TFTPN) and 5,5′,6,6′-tetrahydroxy-3,3,3′,3′-tetramethyl-1,1′-spirobisindane (TTSBI) as precursors. The primary PIM-1 was quite hydrophobic, and thus could not be evenly dispersed in water, resulting in low adsorption capacity for mercury ions (Hg2+). A conversion of nitrile group in PIM-1 to thiol group was then carried out by two steps, namely carboxylation and introduction of thiol groups. The carboxylation made the polymers more active, and the final thiol-functionalization provided the polymers with hydrophilicity and affinity for Hg2+. The thiolethyl modified PIM-1 (assigned as PIM-G) and thiophenyl modified (assigned as PIM-B) possessed maximum Hg2+ adsorption capacity of 136 mg g(-1) and 127 mg g(-1) at pH 5, respectively. Besides, the thiol-functionalized PIMs had fluorescence property and showed potential in sensing for Hg2+.

Vacuum-Ultraviolet Absorption Spectrum of 3-Methoxyacrylonitrile

The high-resolution absorption spectrum of 3-methoxyacrylonitrile (3MAN) was measured between 5.27 and 12.59 eV using a synchrotron-based Fourier-transform spectrometer. It was related to an absolute absorption cross-section scale. Complementary calculations at the DFT-MRCl/aug-cc-pVTZ level of theory document the vertical transition energies and oscillator strengths toward the first 19 states of both the E and Z geometrical isomers of 3MAN. Comparisons with the experimental absorption spectrum reveal the similarities and differences between 3MAN, a bifunctional molecule, with acrylonitrile and methyl-vinylether, where only one functional group is present. As in acrylonitrile, several broad valence transitions were observed up to the ionization limit. They are likely associated with the extended pi-system induced by the nitrile group but might also involve sigma sigma* transitions close to the ionization limit. As in methylvinylether, Rydberg series converging to the ionization limit are absent. This is attributed to a difference in neutral and cationic geometry due to a 60 degrees rotation of the methyl group.

Dicumyl Peroxide used as curing Agent for different Types of Rubber Matrices Part I: Effect of Temperature

Several elastomers were cured with dicumyl peroxide at different vulcanization temperatures. The focus of the work was the investigation of the influence of curing temperature on curing characteristics of rubber compounds. Subsequently, crosslink density and physical mechanical properties of vulcanizates were evaluated. The results demonstrated that higher curing temperatures lead to a total acceleration of cross-linking process. The effect of temperature on the crosslink density was low and was dependent on the structure of tested rubbers. Physicalmechanical properties of vulcanizates were almost not influenced by curing temperature.

Insights on the Pseudo-Enantiomeric Properties of Bifunctional Cinchona Alkaloid Squaramide-Derived Organocatalyst

The use of pseudo enantiomers is a well-known method of achieving products of complementary stereochemistry. Only rarely can different enantiomers of a product be accessed without modulation of the catalyst. Recently, a system was reported wherein two different enantiomers of spirocycles were obtained by a cascade reaction of unsaturated pyrrolin-4-ones with mercaptoacetaldehyde catalyzed by a single optimized cinchona alkaloid squaramide-derived organocatalyst. It was originally proposed that the E/Z geometry of the unsaturated pyrrolin-4-one dictated the stereochemistry of the spirocycle product, but this was not investigated further. In the present work, we have investigated the nature of a pseudo-enantiomeric organocatalyst conformation applying density functional theory calculations for investigating the transition states for the reaction. Furthermore, the influence of the double-bond geometry of the pyrrolin-4-one has been studied beyond what is possible to test experimentally. The results provide a greater understanding for this class of reactions that may be applicable in future methodology development.

Road performance of liquid nitrile-butadiene rubber modified unsaturated polyester resin concrete

Unsaturated polyester resin concrete (UPC) is currently gaining attention in many fields due to its functional compressive capacity and corrosion resistance. However, the toughness of UPC is poor due to the weak resistance to the deformation of the cured unsaturated polyester resin (UP). In this paper, the UP was modified with liquid nitrile-butadiene rubber (LNBR) and further used to make concrete. At the same time, two different initiators were used to cure the UPC and LNBR modified UPC. To study the mechanism and road performance of LNBR modified UPC performance, optical microscopy test, Marshall test, water immersion Marshall test, rutting test, freeze-thaw split test, and infrared spectroscopy experiments were carried out. Test results showed that LNBR could effectively improve the low-temperature toughness of UPC. Although LNBR slightly reduced the Marshall stability and rutting resistance of UPC, it hardly changed the water stability of the UPC. LNBR could crosslink with UP to form a joint body, and the amount of initiator may have a more significant impact on the performance of the UPC and LNBR modified UPC. (C) 2020 Elsevier Ltd.

A integrated process for nitrilase-catalyzed asymmetric hydrolysis and easy biocatalyst recycling by introducing biocompatible biphasic system

The whole-cell nitrilase-catalyzed asymmetric hydrolysis of nitriles is a green and efficient preparation approach for chiral carboxylic acids, but often suffers from toxicity and cell lysis from organic substrates. In this work, a novel integrated process for whole-cell nitrilase-catalyzed asymmetric hydrolysis was developed for the first time by introducing a biocompatible ionic liquid (IL)-based biphasic system. The whole-cell nitrilases displayed an outstanding stability and recyclability in the biphasic system and still retained > 85% activity even after 7 cycles reaction. A preparative-scale fed-batch hydrolysis of o-chloromandelonitrile to (R)-o-chloromandelic acid (RCMA) was performed using the integrated process. The results revealed a yield of 91.3% and a space-time yield of 746.4 g.L-1.d(-1), which are currently the highest reported values for R-CMA biosynthesis. The proposed integrated process avoids substrate inhibition, facilitates the reusability of whole-cell nitrilases, and thus shows great potential for the sustainable production of chiral carboxylic acids.
