Enhanced energy density of poly(arylene ether nitriles) composites filled with surface engineered BaTiO3 nanoparticles

The introduction of nano-sized BaTiO3 (BT) into polymer host matrices brings about promising dielectric and energy storage properties. However, pristine BT tends to aggregate and is difficult to be compatible with polymer matrices, thus requiring surface modification of BT nanoparticles. In this work, gamma-aminopropyl triethoxysilane (KH550) was grafted onto the surface of BT as a shell and amino-functionalized core-shell KH550@BT nanoparticles have been successfully prepared. Thereafter, poly(arylene ether nitrile) (PEN) has been chosen as polymer matrix due to its excellent thermal properties, and xKH550@BT/(1-x)PEN composite films were prepared by solution casting film formation method. The energy density of KH550@BTIPEN composites with 30 wt.% filler loading is 1.30 J cm(-3) (eta = 61.32 %) at 150 MV m(-1), more than 36.84 % increase when compared with pristine PEN polymer (0.95 J cm(-3) at 170 MV m(-1)). Temperature-dependent and frequency-dependent D-E loops confirmed that KH550@BTIPEN composites possess good temperature and frequency stability. (C) 2020 Elsevier B.V. All rights reserved.

Crystal structure of Leishmania mexicana cysteine protease B in complex with a high-affinity azadipeptide nitrile inhibitor

Leishmania mexicana is an obligate intracellular protozoan parasite that causes the cutaneous form of leishmaniasis affecting South America and Mexico. The cysteine protease LmCPB is essential for the virulence of the parasite and therefore, it is an appealing target for antiparasitic therapy. A library of nitrile-based cysteine protease inhibitors was screened against LmCPB to develop a treatment of cutaneous leishmaniasis. Several compounds are sufficiently high-affinity LmCPB inhibitors to serve both as starting points for drug discovery projects and as probes for target validation. A 1.4 angstrom X ray crystal structure, the first to be reported for LmCPB, was determined for the complex of this enzyme covalently bound to an azadipeptide nitrile ligand. Mapping the structure-activity relationships for LmCPB inhibition revealed superadditive effects for two pairs of structural transformations. Therefore, this work advances our understanding of azadipeptidyl and dipeptidyl nitrile structure-activity relationships for LmCPB structure-based inhibitor design. We also tested the same series of inhibitors on related cysteine proteases cathepsin L and Trypanosoma cruzi cruzain. The modulation of these mammalian and protozoan proteases represents a new framework for targeting papain-like cysteine proteases.

Separation of Tire Rubber Overlapping Terahertz Spectra Using Non-Negative Matrix Factorization of Spectral Feature Constraints

With the deepening of the concept of green tires, the effective composition of tire rubberis directly related to the qualification of rubber. But tire rubber is a black analysis system for the inspection department, and it’ sexceedingly crucialto accurately detect rubber components by the existing methods. Terahertz time-domain spectroscopy (THz-TDS) technology has been successfully applied to material detection and analysis, but the terahertz spectral data observed from a complex sample of rubber represents the comprehensive results of several interrelated components or interaction of characteristic components in many cases, where as the actual information contained in the raw data may overlap, which will conversely affect the analysis of the components in the rubber mixture. In order to solve the problem of terahertz spectral overlap, the characteristics of continuous smoothing of terahertz spectral matrix and sparse concentration matrix are combined this paper, then the 2 norms with smoothing characteristics and the 1/2 norm with sparsity characteristics into the non-negative matrix factorization method is introduced, which are applied to the separation of terahertz aliased spectra, so as eparation method of terahertz aliasing spectral based on spectral feature Constrained Non-negative Matrix Factorization (CNMF) is proposed. Firstly, nitrile-butadiene rubber combined with vulcanization accelerator 2-Mercaptobenzothizzole(MBT) to form a binary mixture in diverse proportions, and it combined with vulcanization accelerators MBT and tetramethyl thiuram monosulfide (TMTM) to form a ternary mixture in different proportions. Then the terahertz time domain spectrum of all samples ismeasured by terahertz spectroscopy system, which the measured data is subjected too btain a corresponding absorbance spectrum. Further, principal component analysis is performed on the obtained spectral matrix to initially determine the number of components of the mixture. Finally, the Non-negative Matrix Factorization (NMF), Non-negative Matrix Factorization based on pure variables initialization(PNMF) and CNMF methods are used to the decomposition of the mixture data matrix and spectral analysis of the aliased spectrum. The results show that the separation effect of the CNMF algorithm is better than that of NMF and PNMF method, and the corresponding results of the characteristic absorption peak are accurate. In addition, the correlation coefficients of separation results for different component mixtures are higher than 89%, and the spectral angles are less than 0.5 with a higher reduction degree of purity spectrum. Therefore, the constrained non-negative matrix factorization algorithm is introduced into the separation of terahertz aliasing spectra, which is preferable to extract the characteristic information of single components in complex mixtures and provides a better foundation for the qualitative analysis and quantitative calculation of subsequent terahertz multicomponent mixtures as well as the considerable research prospects in the field of quality testing of green tires and rubber.

Catalytic Direct Construction of Cyano-tetrazoles

Cyano-tetrazole is the first reported compound that bears four nitrogen atoms in a single five-membered ring. This unique molecular scaffold has long been ignored after its discovery in 1885, mainly attributed to the scarcity of available synthetic methods. Indeed, the most popular approach to tetrazoles (that is the cycloaddition reaction between nitriles and azides) has inevitably excluded the possibility of introducing valuable cyano groups to decorate the final heterocyclic cores. Here, we describe a completely different disconnection strategy to the long time-pursued cyano-tetrazoles via a simple, direct, and practical cycloaddition transformation between readily accessible aryl diazonium salts and diazoacetonitrile. This method provides both regioisomers of disubstituted tetrazoles from the same set of starting materials in a metal cation controlled fashion.

Mining the Cambridge Database for theoretical chemistry. Mi-LJC: a new set of Lennard-Jones-Coulomb atom-atom potentials for the computer simulation of organic condensed matter

A set of 377 crystal structures extracted from the Cambridge Structural Database and matched to the experimental sublimation enthalpies of the corresponding materials is used to calibrate a new intermolecular potential field for organic compounds. The scheme includes usual R-6-R-12 Lennard-Jones dispersion-repulsion terms, with parameters for C, H, N, O, S and the halogens, fully transferable and unique for each atomic species without distinction among the hybridization states of carbon, or among valence states like carbonyl or ether oxygen or aza, nitro or nitrile nitrogen. This great economy in the number of parameters is countered by the need for using accurate coulombic terms over atomic point charges derived for each molecule from the fitting of the electrostatic potential (ESP method) of an ab initio MP2/6-31G** wavefunction. The potential scheme so derived, called Mi-LJC (Milano Lennard-Jones Coulomb), is able to reproduce the 377 sublimation enthalpies by the calculated lattice energies with an average percent deviation of 5% and a rmsd of 6.7 kJ mol(-1). The potential scheme is also tested and proved applicable for the Monte Carlo simulation of some organic liquids, as well as for the molecular dynamic simulation of liquids and crystals.

Oxalato bridged coordination polymer of manganese(iii) involving unconventional OMIDLINE HORIZONTAL ELLIPSIS pi-hole(nitrile) and antiparallel nitrileMIDLINE HORIZONTAL ELLIPSISnitrile contacts: antiproliferative evaluation and theoretical studies

A new oxalato bridged polymeric Mn(iii) coordination compound, {[Mn-2(eta(2)-C2O4)(H2O)(2)Cl-4] 2(4-CNpy)}(n) (1) (C2O4 = oxalate, 4-CNpy = 4-cyanopyridine), has been synthesized and characterized using elemental analysis, and spectroscopic (IR, electronic, XPS) and single crystal X-ray diffraction techniques. Electronic and XPS analyses of the compound justify the presence of a Mn(iii) center that is charge compensated by the two chlorido ligands and the oxygen atom of the bridged oxalate. 4-CNpy molecules in the lattice form unconventional H-bonded supramolecular dimers in the solid state assisted by antiparallel CNMIDLINE HORIZONTAL ELLIPSISCN dipoleMIDLINE HORIZONTAL ELLIPSISdipole interactions, which has been confirmed using QTAIM and NCI plot analysis and supported by MEP surface analysis. Remarkably, this dimer concurrently establishes a weak anion-pi interaction with the coordinated chlorido ligand. Unexpectedly, QTAIM analysis reveals the existence of an interesting OMIDLINE HORIZONTAL ELLIPSIS pi-hole(nitrile) contact involving the coordinated water molecule and the nitrile moiety that also contributes to the stabilization of the dimer in the crystal structure. To the best of our knowledge, the existence of such pi-hole interaction involving nitrile derivatives has not been reported before. Compound 1 has been further screened for anticancer activity in the malignant Dalton’s lymphoma (DL) cell line and the results were confirmed by molecular docking and pharmacophore features. Our findings indicated that the cytotoxicity of compound 1 is initially increased in a dose dependent manner (0.01-1 mu M) and then decreased (5-10 mu M), which is also affected by the reactive oxygen species (ROS) in the cells. Interestingly, very low cytotoxicity (5-14%) was observed in the case of healthy cells (PBMC) for similar experimental conditions.

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+.

Mechanistic Vistas of Trivalent Nitrogen Compound Reduction by Samarium Diiodide

In trivalent nitrogen compounds, the nitrogen lone pair is highly amenable to bind to samarium iodide prior to electron transfer. As SmI2 is more azaphilic than oxophilic, its affinity to the nitrogen lone pair is more pronounced in aza substrates than in the analogous carbonyl compounds. The impact of this binding is very large in terms of reaction rate and at the same time gives rise to unique mechanistic phenomena, which include unusual kinetic rate orders, catalysis by quantum dots, and remote functionalization. Even reduction of nitriles was found to be affected by this coordination to SmI2. This review focuses on the reduction mechanisms of three groups of compounds: imines, azobenzene, and nitriles.

Cu-catalyzed cyanomethylation of imines and alpha,beta-alkenes with acetonitrile and its derivatives

We describe copper-catalyzed cyanomethylation of imines and alpha,beta-alkenes with a methylnitrile source and provide an efficient route to synthesize arylacrylonitriles and beta,gamma-unsaturated nitriles. This method tolerates aliphatic and aromatic alkenes substituted with a variety of functional groups such as F, Cl, Br, Me, OMe, tert-Bu, NO2, NH2 and CO2H with good to excellent yields (69-98%). These systems consist of inexpensive, simple copper catalyst and acetonitrile with its derivatives (alpha-bromo/alpha-iodo-acetonitrile) and are highly applicable in the industrial production of acrylonitriles.

Mullins Effect and Its Reversibility for Thermoplastic Vulcanizates Based on Ethylene-Acrylic Acid Copolymer/Nitrile-Butadiene Rubber Blends

Mullins effect during uniaxial cyclic compression tests, together with its reversibility, of ethylene-acrylic acid copolymer (EAA)/nitrile-butadiene rubber (NBR) thermoplastic vulcanizates (TPVs) were investigated systematically. The results showed that EAA/NBR TPVs had excellent mechanical properties when the weight ratio was 40/60. Morphology studies showed that sphere-like NBR particles were dispersed evenly in the etched TPVs surface with diameters of 5-8 mu m. The experimental results of Mullins effect indicated that a stress softening phenomenon in the stress-strain curves of EAA/NBR TPVs during the uniaxial loading-unloading cycles could be observed obviously; moreover, the reversibility of Mullins effect could be significantly enhanced by increasing heat treatment temperature.
