A new methodology for the highly efficient and atom-economic oxidation of alcohols and benzylic compounds to the corresponding aldehydes and ketones with environmental-friendly hydrogen peroxide using a magnetic MOF nanocatalyst has been developed. We demonstrated that the resulting magnetic nanocomposite CoFe2O4@SiO2@MIL-53(Fe) can show excellent catalytic performances in the highly selective oxidation at room temperature, based on a synergetic effect between iron sites and CoFe2O4@SiO2. The nanocatalyst offers simple operation for recovery and the recycling test showed that it could be reused for successive runs without significant degradation in catalytic activity.

Photonic materials derived from the [closo-B10H10](2-) anion: tuning photophysical properties in [closo-B10H8-1-X-10-(4-Y-NC5H5)](-)

The parent pyridine [closo-B10H9-1-NC5H5](-) was substituted either at the antipodal B(10) position with CN, OAc, N-3, I, Br, SCN, pyridine, OEt, and morpholine, or at the C(4) position of the pyridine ring with CN, COOEt, Me, and OMe groups. The substituent effects on electronic absorption and emission properties, and also on the boron cage geometry were investigated experimentally and with DFT (B3LYP/Def2TZVP) computational methods. Experimental and theoretical results were correlated with Hammett sigma(p) parameters. Fluorescence was also investigated in the solid state and from aggregates (AIE). Solvent effects on photophysical properties of [closo-B10H9-1-NC5H5](-) were correlated with E(T)30 parameters, giving a slope of 0.71 for absorption and 0.17 for emission. Results demonstrated the substantial impact of the B(10) substituent on the HOMO and the C(4) substituent on the LUMO of the derivatives, which allows variation of the energy of the (pi,pi*) intramolecular charge transfer band in the range of 330-450 nm, and the emission energy in the range of 530-580 nm in MeCN solutions. The substituent effect on excitation energy is 2.4 times greater for substitution at the pyridine ring (LUMO control) than for the B(10) position (HOMO control). Additivity of the substituent effect was tested on [closo-B10H8-1-(NC5H4CN)-10-OEt](-) with lambda(max) = 501.5 nm in MeCN and 560 nm in THF. These studies indicate that a substantial degree of control over photophysical properties is possible in derivatives of [closo-B10H10](2-) through a combination of substituent and solvent (medium) effects.

Metabolic regulation of Kv channels and cardiac repolarization by Kv beta 2 subunits

Voltage-gated potassium (Kv) channels control myocardial repolarization. Pore-forming Kv alpha proteins associate with intracellular Kv beta subunits, which bind pyridine nucleotides with high affinity and differentially regulate channel trafficking, plasmalemmal localization and gating properties. Nevertheless, it is unclear how Kv beta subunits regulate myocardial K+ currents and repolarization. Here, we tested the hypothesis that Kv beta 2 subunits regulate the expression of myocardial Kv channels and confer redox sensitivity to Kv current and cardiac repolarization. Co-immunoprecipitation and in situ proximity ligation showed that in cardiac myocytes, Kv beta 2 interacts with Kv1.4, Kv1.5, Kv4.2, and Kv4.3. Cardiac myocytes from mice lacking Kcnab2 (Kv beta 2(-/-)) had smaller cross sectional areas, reduced sarcolemmal abundance of Kv alpha binding partners, reduced I-to, I-K,I-slow1, and I-K,I-slow2 densities, and prolonged action potential duration compared with myocytes from wild type mice. These differences in Kv beta 2(-/-) mice were associated with greater P wave duration and QT interval in electrocardiograms, and lower ejection fraction, fractional shortening, and left ventricular mass in echocardiographic and morphological assessments. Direct intracellular dialysis with a high NAD(P)H:NAD(P)(+) accelerated Kv inactivation in wild type, but not Kv beta 2(-/-) myocytes. Furthermore, elevated extracellular levels of lactate increased [NADH](i) and prolonged action potential duration in wild type cardiac myocytes and perfused wild type, but not Kv beta 2(-/-), hearts. Taken together, these results suggest that Kv beta 2 regulates myocardial electrical activity by supporting the functional expression of proteins that generate I-to and I-K,I-slow, and imparting redox and metabolic sensitivity to Kv channels, thereby coupling cardiac repolarization to myocyte metabolism.

Platinum catalysts supported on ZSM5 zeolites with a hierarchical pore structure: characterization and performance in n-hexadecane hydroconversion

HZSM5 zeolites with a hierarchical pore structure were prepared from a microporous one using the top-down methodology by treatment with a sodium hydroxide solution in optimal conditions of time, alkali concentration and temperature. These materials were used as supports for platinum to produce bifunctional hydroconversion catalysts. The activity in n-hexadecane hydroconversion was one order of magnitude larger on Pt supported on the mesoporous than on the untreated zeolite and one order of magnitude larger than that of the supports. All Pt catalysts and supports were more selective to hydrocracking than to hydroisomerization, but the initial selectivity for hydroisomerization of the Pt catalysts supported on the mesoporous supports was considerably smaller than that of all other materials, including the supports. This was attributed to a smaller mass transfer limitation with the Pt catalysts supported on the mesoporous zeolites. All supports and catalysts were extensively characterized by techniques such as X-ray diffraction, hydrogen chemisorption, TPD of ammonia, IR spectroscopy of adsorbed pyridine, MAS Si-29 and Al-27 solid state NMR and transmission electron microscopy.

Zeolite-assisted core-shell redox catalysts for efficient light olefin production via cyclohexane redox oxidative cracking

This study reports a highly effective redox catalyst platform, i.e. composites of metal-exchanged ZSM5 and CaMn0.75Fe0.25O3@Na2WO4, for low temperature (<650 degrees C) redox oxidative cracking (ROC) of naphtha using a cyclohexane model compound. TEM-EDX showed that Na2WO4 shell covers the CaMn0.75Fe0.25O3 bulk and the zeolite + CaMn0.75Fe0.25O3@Na2WO4 composite can achieve autothermal conversion of cyclohexane under a cyclic redox scheme by selective oxidation of by-product H-2 to H2O. Meanwhile, NH3-TPD and pyridine FTIR experiments confirmed that the BrOnsted acidity of ZSM5 was primarily responsible for cyclohexane activation. Compared to each catalyst component alone, the synergistic effect of the composite redox catalysts resulted in substantially higher olefin yield (up to 75%), lower alkane yield (similar to 5%), lower aromatic yield (similar to 10%), and higher lattice oxygen utilization (up to 4 wt.cat%). Based on TGA-DSC experiments and ASPEN Plus analysis, the multi-functional redox catalysts facilitate autothermal conversion of cyclohexane with high lattice oxygen utilization from the redox catalysts. Due to the highly effective redox catalysts performance and the ease for heat integration, the novel ROC process has the potential for more energy-efficient light olefins production with significantly reduced CO2 emissions when compared to naphtha steam cracking.

Synthesis of nanorod MOF catalyst containing Cu2+ and its selective oxidation of styrene

Different from the traditional aldimine condensation reaction, N-containing ligand: pyridine-2-formaldehyde was selected as the source of aldehyde group, and NH2-MIL-53(Al) containing a large number of amino functional groups was took as the carrier, transition metal Cu2+ coordinated with N-containing ligand to prepare a new and more stable MOFs catalyst named Cu@Al-MIL-53-P21. The catalyst exhibited a cross-linked nanorod morphology. The effect of the morphology on the catalytic oxidation activity of styrene was studied, the results showed that the catalyst could not only promote the production of benzaldehyde, but also inhibit the production of benzoic acid and phenylacetaldehyde. In addition, the optimal reaction conditions and the reaction mechanism were also discussed in this paper.

Block copolymer-nanodiamond coassembly in solution: towards multifunctional hybrid materials

Polymer-nanodiamond composites are excellent candidates for the fabrication of multifunctional hybrid materials. They integrate polymer flexibility and exceptional properties of nanodiamonds (NDs), such as biocompatibility, mechanical strength, color centers, and chemically-tailored surfaces. However, their development is hindered by the challenge of ensuring that NDs are homogeneously distributed in the composites. Here, we exploit colloidal coassembly between poly(isoprene-b-styrene-b-2-vinyl pyridine) (ISV) block copolymers (BCPs) and NDs to avoid ND self-agglomeration and direct ND spatial distribution. NDs were first air oxidized at 450 degrees C to obtain stable dispersions in dimethylacetamide (DMAc). By adding ISV into the dispersions, patchy hybrid micelles were formed due to H-bonds between NDs and ISV. The ISV-ND coassembly in DMAc was then used to fabricate nanocomposite films with a uniform sub-50 nm ND distribution, which has never been previously reported for an ND loading (phi(ND)) of more than 50 wt%. The films exhibit good transparency due to their well-defined nanostructures and smoothness and also exhibit an improved UV-absorption and hydrophilicity compared to neat ISV. More intriguingly, at a phi(ND) of 22 wt%, ISV and NDs coassemble into a network-like superstructure with well-aligned ND strings via a dialysis method. Transmission electron microscopy and dynamic light scattering measurements suggest a complex interplay between polymer-polymer, polymer-solvent, polymer-ND, ND-solvent, and ND-ND interactions during the formation of structures. Our work may provide an important foundation for the development of hierarchically ordered nanocomposites based on BCP-ND coassembly, which is beneficial for a wide spectrum of applications from biotechnology to quantum devices.

delta-Regioselective heteroarylation of free alcohols through 1,5-hydrogen-atom transfer

An efficient silver-catalyzed d-regioselective C(sp(3))-H heteroarylation of free alcohols has been developed. Various alcohols reacted with quinolines, isoquinoline, pyridines, pyrimidine, phthalazine, 4-hydroxyquinazoline, acridine, quinoxaline and pyrazine to give the corresponding C(sp(2))-H alkylation products in 31-89% yields. Notably, all types (1 degrees, 2 degrees, and 3 degrees) of d-C(sp(3))-H bonds in the alcohols could be regioselectively activated. This protocol provides a platform to access divergent functionalizations of alcohols and heteroaryls by forming the challenging d-selective C(sp(3))-C(sp(2)) bond.
