Ni2P Nanoalloy as an Air-Stable and Versatile Hydrogenation Catalyst in Water: P-Alloying Strategy for Designing Smart Catalysts

Non-noble metal-based hydrogenation catalysts have limited practical applications because they exhibit low activity, require harsh reaction conditions, and are unstable in air. To overcome these limitations, herein we propose the alloying of non-noble metal nanoparticles with phosphorus as a promising strategy for developing smart catalysts that exhibit both excellent activity and air stability. We synthesized a novel nickel phosphide nanoalloy (nano-Ni2P) with coordinatively unsaturated Ni active sites. Unlike conventional air-unstable non-noble metal catalysts, nano-Ni2P retained its metallic nature in air, and exhibited a high activity for the hydrogenation of various substrates with polar functional groups, such as aldehydes, ketones, nitriles, and nitroarenes to the desired products in excellent yields in water. Furthermore, the used nano-Ni2P catalyst was easy to handle in air and could be reused without pretreatment, providing a simple and clean catalyst system for general hydrogenation reactions.

Theoretical Investigations on the Oxidation of Heptafluoro-iso-butyronitrile by Atomic Oxygen in Dielectric Breakdown

Heptafluoro-iso-butyronitrile [(CF3)(2)CFCN, in abbr., C4] with CO2 gas mixture is a promising dielectric candidate to replace sulfur hexafluoride (SF6) for the sake of environmental concern. Detailed mechanisms for the reactions of C4 with atomic oxygen in both triplet and singlet due to dissociation of CO2 were proposed using high-level ab initio methods including density functional theory, quadratic complete basis set, multireference Rayleigh-Schrodinger perturbation theory, and state-averaged multiconfiguration self-consistent field. The reaction of C4 with O(P-3) proceeds via the stepwise C-O and N-O addition/elimination and direct displacement mechanisms. The reaction paths are bifurated into cis and trans conformations. The predominant product channel is the C-O association with the barriers 6.1-6.8 kcal/mol to form the C3F7C(O)N intermediates and followed by the C-C bond cleavage to produce C3F7 and NCO radicals. On the singlet surface, the three-center intramolecular conversion to form the C3F7OCN isomer becomes competitive. The singlet-triplet intersystem crossing is favorable due to the significant spin-orbital coupling. Master equation calculations were carried out to obtain the temperature- and pressuredependent rate coefficients and yields of the O(P-3) + C4 reaction and were compared with the analogous reactions of nitriles. It was found that only the NCO + C3F7 product channel is significant. The overall rate coefficients are pressure-independent in the range 1-10 atm and can be expressed by k(infinity)(T/K)=(6.41 +/- 0.22) x 10(-13)(T/298)(1.30 +/- 0.01)e(-(3241.5 +/- 24.5)/T) cm(3) molecule(-1 )s(-1) . The present theoretical work provides useful insights into the breakdown diagnostic of the C4/CO2 insulation gas.

Volatile Organic Compounds (VOCs) of Endophytic Fungi Growing on Extracts of the Host, Horseradish (Armoracia rusticana)

The interaction between plant defensive metabolites and different plant-associated fungal species is of high interest to many disciplines. Volatile organic compounds (VOCs) are natural products that are easily evaporated under ambient conditions. They play a very important role in inter-species communication of microbes and their hosts. In this study, the VOCs produced by 43 different fungal isolates of endophytic and soil fungi during growth on horseradish root (Armoracia rusticana) extract or malt extract agar were examined, by using headspace-gas chromatography-mass spectrometry (headspace-GC-MS) and a high relative surface agar film as a medium. The proposed technique enabled sensitive detection of several typical VOCs (acetone, methyl acetate, methyl formate, ethyl acetate, methyl butanol isomers, styrene, beta-phellandrene), along with glucosinolate decomposition products, including allyl cyanide and allyl isothiocyanate and other sulfur-containing compounds-carbon disulfide, dimethyl sulfide. The VOC patterns of fungi belonging to Setophoma, Paraphoma, Plectosphaerella, Pyrenochaeta, Volutella, Cadophora, Notophoma, and Curvularia genera were described for the first time. The VOC pattern was significantly different among the isolates. The pattern was indicative of putative myrosinase activity for many tested isolates. On the other hand, endophytes and soil fungi as groups could not be separated by VOC pattern or intensity.

Chemical-Physical Characterization of a Binary Mixture of a Twist Bend Nematic Liquid Crystal with a Smectogen

Nematic twist-bend phases (N-TB) are new types of nematic liquid crystalline phases with attractive properties for future electro-optic applications. However, most of these states are monotropic or are stable only in a narrow high temperature range. They are often destabilized under moderate cooling, and only a few single compounds have shown to give room temperature N-TB phases. Mixtures of twist-bend nematic liquid crystals with simple nematogens have shown to strongly lower the nematic to N-TB phase transition temperature. Here, we examined the behaviour of new types of mixtures with the dimeric liquid crystal [4 ‘,4 ‘-(heptane-1,7-diyl)bis(([1 ‘,1 ”-biphenyl]4 ”-carbo-nitrile))] (CB7CB). This now well-known twist-bend nematic liquid crystal presents a nematic twist-bend phase below T approximate to 104 degrees C. Mixtures with other monomeric alkyl or alkoxy -biphenylcarbonitriles liquid crystals that display a smectic A (SmA) phase also strongly reduce this temperature. The most interesting smectogen is 4 ‘-Octyl-4-biphenylcarbonitrile (8CB), for which a long-term metastable N-TB phase is found at room and lower temperatures. This paper presents the complete phase diagram of the corresponding binary system and a detailed investigation of its thermal, optical, dielectric, and elastic properties.

A Schiff-base receptor based on phenolphthalein derivate appended 2-furoic hydrazide: Highly sensitive fluorogenic turn on chemosensor for Al3+

Herein, a novel phenolphthalein-derived Schiff base fluorescence probe FF2H has readily been synthesized and applied to be fluorescence ”turn-on. probe for Al3+ sensing in aceto-nitrile (ACN) : HEPES (5.0 mu M, 50/50, v/v, pH = 7). The emission response of the chemo-sensor FF2H toward Al3+ depends on the metal chelation-enhanced fluorescence (CHEF) effect and CHEF prevents C = N isomerisation, the excited state intra-molecular (ESIPT), and PET process of the chemosensor FF2H. FF2H-Al3+ complexation (1:2 stoichiometry) was revealed by Job’s method and H-1-NMR titration. The detection limit (LOD) (3s/K) value of FF2H for Al3+ was estimated to be 7.0 nM, demonstrating that the chemosensor FF2H could be employed as a fluorogenic ”turn-on chemosensor to effectively and selectively to recognize Al3+.

Water mediated procedure for preparation of stereoselective oximes as inhibitors of MRCK kinase

Stereoselective aldoximes, preferably Z form have been obtained from ci-cyano substituted carbonyl conjugated alkenes. This reaction occurs through Michael addition type reaction followed by retro-Knoevenagel reaction without transition-metal catalysis via C-C bond cleavage. These oximes are evaluated against cancer cell lines employing mechanistic study. Two oximes showed significant cytotoxic activity, which through in silico studies were found to inhibit MRCK Kinase, responsible for metastatic spread of cancer mortality.

Expanding Access to Remdesivir via an Improved Pyrrolotriazine Synthesis: Supply Centered Synthesis

Pyrrolotriazine 1 is an important precursor to remdesivir. Initial results toward an efficient synthesis are disclosed consisting of sequential cyanation, amination, and triazine formation beginning from pyrrole. This route makes use of highly abundant, commoditized raw material inputs. The yield of triazine was doubled from 31% to 59%, and the synthetic step count was reduced from 4 to 2.

Nitric Oxide Modulating Calcium Store for Ca2+-Initiated Cancer Therapy

Ions are essential to body, but sometimes can evolve into weapons to attack and destroy cells without systematic toxicity and drug resistance. Inspired by nitric oxygen as neurotransmitter in mediating Ca2+ release, NO nanodonors with high photoreactivity and stability are constructed with upconversion nanoparticles (UCNPs) coated by zeolitic nitro-/nitrile-imidazole framework-82 (ZIF-82), capable of near-infrared light (NIR) triggered NO generation and berbamine (BER) release, to achieve cancer therapy with the stored Ca2+ in cells. The spatial confinement effect of 2-nitroimidazole in ZIF-82 enables NO-releasing with tunable release kinetics. NO turns on the ryanodine receptors overexpressed in cancer cells for abrupt Ca2+ elevation; meanwhile, berbamine (BER) turns Ca2+-excretion pumps off to inhibit calcium efflux, resulting in intracellular Ca2+ overload induced apoptosis. This work provides the first example of regulating endogenous ions for cell killing, which holds promise as an effective cancer therapeutics that is complementary to traditional chemotherapeutics.

A Ru-Complex Tethered to a N-Rich Covalent Triazine Framework for Tandem Aerobic Oxidation-Knoevenagel Condensation Reactions

Herein, a highly N-rich covalent triazine framework (CTF) is applied as support for a Ru-III complex. The bipyridine sites within the CTF provide excellent anchoring points for the [Ru(acac)(2)(CH3CN)(2)]PF6 complex. The obtained robust Ru-III@bipy-CTF material was applied for the selective tandem aerobic oxidation-Knoevenagel condensation reaction. The presented system shows a high catalytic performance (>80% conversion of alcohols to alpha, beta-unsaturated nitriles) without the use of expensive noble metals. The bipy-CTF not only acts as the catalyst support but also provides the active sites for both aerobic oxidation and Knoevenagel condensation reactions. This work highlights a new perspective for the development of highly efficient and robust heterogeneous catalysts applying CTFs for cascade catalysis.
