ULX behaviour: The ultraluminous state, winds and interesting anomalies
Authors: Roberts T. P. , Middleton M. J. , Sutton A. D. , Mezcua M. , Walton D. J. , Heil L. M. 
Published: May 2016

AbstractRecent evidence – in particular the hard X‐ray spectra obtained by NuSTAR, and the large amplitude hard X‐ray variability observed when ULXs show soft spectra ‐ reveals that common ultraluminous X‐ray source (ULX) behaviour is inconsistent with known sub‐Eddington accretion modes, as would be expected for an intermediate‐mass black hole (IMBH). Instead, it appears that the majority of ULXs are powered by super‐Eddington accretion onto stellar‐mass black holes. Here, we will review work that delves deeper into ULX spectral‐timing behaviour, demonstrating it remains consistent with the expectations of super‐Eddington accretion. One critical missing piece from this picture is the direct detection of the massive, radiatively‐driven winds expected from ULXs as atomic emission/absorption line features in ULX spectra; we will show it is very likely these have already been detected as residuals in the soft X‐ray spectra of ULXs. Finally, we will discuss ULXs that do not appear to conform to the emerging ULX behaviour patterns. In particular we discuss the implications of the identification of a good IMBH candidate as a background QSO; and the confirmation of an IMBH/ULX candidate in the galaxy NGC 2276 via the radio/X‐ray fundamental plane.

High‐energy monitoring of Seyfert galaxies: The case of NGC 4593
Authors: Ursini F. , Petrucci P.‐O. , Matt G. , Bianchi S. , Cappi M. , De Marco B. , De Rosa A. , Malzac J. , Ponti G. 
Published: May 2016

AbstractWe discuss preliminary results from a joint XMM‐Newton and NuSTAR monitoring program on the active galactic nucleus NGC 4593, consisting of 5×20 ks observations, spaced by two days, performed in January 2015. The source is found to be variable, both in flux and spectral shape, on time scales as short as a few ks. The spectrum clearly softens when the source brightens. A simple timing analysis suggests the presence of a variable soft excess that correlates with the primary continuum. (© 2016 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Compositae Plants Differed in Leaf Cuticular Waxes between High and Low Altitudes
Authors: Guo Na , Gao Jianhua , He Yuji , Guo Yanjun 
Published: May 2016

We sampled eight Compositae species at high altitude (3482 m) and seven species at low altitude (220 m), analyzed the chemical compositions and contents of leaf cuticular wax, and calculated the values of average chain length (ACL), carbon preference index (CPI), dispersion (d), dispersion/weighted mean chain length (d/N), and C31/(C31 + C29) (Norm31). The amounts of total wax and compositions were significantly higher at high altitude than at low altitude, except for primary alcohol, secondary alcohol, and ketone. The main n‐alkanes in most samples were C31, C29, and C33. Low altitude had more C31 and C33, whereas more C29 occurred at high altitude. The ACL, CPI, d, d/N, and Norma 31 were higher at low altitude than at high altitude. The fatty acid and primary alcohol at low altitude contained more C26 homologous than at high altitude. More short‐chain primary alcohols were observed at high altitude. At low altitude, the primary alcohol gave on average the largest amount, while it was n‐alkane at high altitude. These results indicated that the variations of leaf cuticular waxes benefited Compositae plants to adapt to various environmental stresses and enlarge their distribution.

Published: May 2016

AbstractDetailed investigations of a photocatalytic system capable of producing hydrogen under pre‐catalytic aerobic conditions are reported. This system consists of the NHC precursor chromophore [Ru(tbbpy)2(RR′ip)][PF6]3 (abbreviated as Ru(RR′ip)[PF6]3; tbbpy=4,4′‐di‐tert‐butyl‐2,2′‐bipyridine, RR′ip=1,3‐disubstituted‐1H‐imidazo[4,5‐f][1,10]phenanthrolinium), the reduction catalyst Co(dmgH)2 (dmgH=dimethylglyoximato), and the electron donor ascorbic acid (AA). Screening studies with respect to solvent, cobaloxime catalyst, electron donor, pH, and concentrations of the individual components yielded optimized photocatalytic conditions. The system shows high activity based on Ru, with turnover numbers up to 2000 under oxygen‐free and pre‐catalytic aerobic conditions. The turnover frequency in the latter case was even higher than that for the oxygen‐free catalyst system. The Ru complexes show high photostability and their first excited state is primarily located on the RR′ip ligand. X‐ray crystallographic analysis of the rigid cyclophane‐type ligand dd(ip)2(Br)2 (dd(ip)2=1,1′,3,3′‐bis(2,3,5,6‐tetramethyl‐1,4‐phenylene)bis(methylene)bis(1H‐imidazo[4,5‐f][1,10]phenanthrolinium)) and the catalytic activity of its Ru complex [{(tbbpy)2Ru}2(μ‐dd(ip)2)][PF6]6 (abbreviated as Ru2(dd(ip)2)[PF6]6) suggest an intermolecular catalytic cycle.
Mechano‐Responsive, Thermo‐Reversible, Luminescent Organogels Derived from a Long‐Chained, Naturally Occurring Fatty Acid
Authors: Zhang Mohan , Weiss Richard G. 
Published: May 2016

AbstractThe gelating ability of an α‐diketo derivative of oleic acid, 9,10‐dioxooctadecanoic acid (DODA), is investigated. DODA can gelate aromatic liquids and many other organic liquids. By contrast, none of the liquids examined can be gelated by the methyl ester of DODA. DODA is a more efficient gelator than stearic acid and the monoketo derivative due to its more extensive intermolecular dipole–dipole interactions. Formation of organogels of DODA can be induced by both thermal and mechanical stimuli, during which the luminescent and mechanical properties can be modulated significantly. The emission from DODA in 1‐octanol exhibits a large, reversible, hypsochromic shift (≈25 nm) between its thermally cycled gel and sol states. The emission changes have been exploited to probe the kinetics of the aggregation and deaggregation processes. DODA is the simplest gelator of which we are aware that exhibits a reversible shift in the emission. Although the self‐assembled fibrillar networks of the DODA gels in 1‐octanol, benzonitrile, or silicone oil are crystalline, isothermal mechanical cycling between the gel and the sol states is rapid and can be repeated several times (i.e., they are thixotropic). The single‐crystal structure of DODA indicates that extended intermolecular dipole–dipole interactions are crucial to the thermal and mechanical formation of DODA gels and the consequential changes in emissive and mechanical properties. From analyses of structural information, gelator packing, and morphology differences, we hypothesize that the mechanical destruction and reformation of the gel networks involves interconversion between the 3D networks and 1D fiber bundles. The thermal processes allow the fibrillar 3D networks and their 0D components (i.e., isolated molecules or small aggregates of DODA) to be interconverted. These results describe a facile approach to the design of mechano‐responsive, thermo‐reversible gels with control over their emission wavelengths.
Alkali‐Metal‐Ion‐Functionalized Graphene Oxide as a Superior Anode Material for Sodium‐Ion Batteries

Published: May 2016

AbstractAlthough graphene oxide (GO) has large interlayer spacing, it is still inappropriate to use it as an anode for sodium‐ion batteries (SIBs) because of the existence of H‐bonding between the layers and ultralow electrical conductivity which impedes the Na+ and e− transformation. To solve these issues, chemical, thermal, and electrochemical procedures are traditionally employed to reduce GO nanosheets. However, these strategies are still unscalable, consume high amounts of energy, and are expensive for practical application. Here, for the first time, we describe the superior Na storage of unreduced GO by a simple and scalable alkali‐metal‐ion (Li+, Na+, K+)‐functionalized process. The various alkali metals ions, connecting with the oxygen on GO, have played different effects on morphology, porosity, degree of disorder, and electrical conductivity, which are crucial for Na‐storage capabilities. Electrochemical tests demonstrated that sodium‐ion‐functionalized GO (GNa) has shown outstanding Na‐storage performance in terms of excellent rate capability and long‐term cycle life (110 mAh g−1 after 600 cycles at 1 A g−1) owing to its high BET area, appropriate mesopore, high degree of disorder, and improved electrical conductivity. Theoretical calculations were performed using the generalized gradient approximation (GGA) to further study the Na‐storage capabilities of functionalized GO. These calculations have indicated that the Na−O bond has the lowest binding energy, which is beneficial to insertion/extraction of the sodium ion, hence the GNa has shown the best Na‐storage properties among all comparatives functionalized by other alkali metal ions.
Syntheses of 5′‐Nucleoside Monophosphate Derivatives with Unique Aminal, Hemiaminal, and Hemithioaminal Functionalities: A New Class of 5′‐Peptidyl Nucleotides
Authors: De Swarup , Groaz Elisabetta , Margamuljana Lia , Herdewijn Piet 
Published: May 2016

AbstractA number of synthetically useful transformations have been developed to generate novel 5′‐peptidyl nucleoside monophosphate analogues that incorporate sensitive phosphoaminal, ‐hemiaminal or ‐hemithioaminal functionalities. The strategies adopted entailed the coupling between dipeptides, which enclose a reactive Cα‐functionalized glycine residue and phosphate or phosphorothioate moieties. These developments led to potentially powerful and general methodologies for the preparation of α‐phosphorylated pseudopeptides as well as nucleoside monophosphate mimics. The resulting conjugates are of interest for a variety of important applications, which range from drug development to synthetic biology, as pronucleotides or artificial building blocks for the enzymatic synthesis of xenobiotic information systems. The potential of all dipeptide‐TMP conjugates as pyrophosphate mimics in the DNA polymerization reaction was tested, and the influence of the nature of the linker was evaluated by in vitro chain elongation assay in the presence of wild‐type microbial DNA polymerases.
Ruthenocene‐Type Complexes of N‐Fused Porphyrins
Authors: Toganoh Motoki , Matsuo Hideaki , Sato Ayumi , Furuta Hiroyuki 
Published: May 2016

AbstractRuthenocene‐type hybrid complexes with N‐fused porphyrinato ligands, [Ru(NFp)Cp] (NFp=N‐fused porphyrin, Cp=cyclopentadienyl), have been prepared and characterized by NMR and UV/Vis/NIR spectroscopy, cyclovoltammetry, and X‐ray crystallography. [Ru(NFp)Cp] is a common low‐spin ruthenium(II) complex and shows strong aromaticity. The Ru–Cp distance (1.833 Å) in [Ru(NFp)Cp] is comparable to that in [RuCp2] (1.840 Å). DFT calculations on [Ru(NFp)Cp] showed the unequivocal contribution of the RuCp moiety as well as the NFp moiety to both the HOMO and LUMO, constructing a three‐dimensional d–π conjugated system. The HOMO–LUMO gaps of [Ru(NFp)Cp] are insensitive to the substituents on the NFp ligand, which is illustrated spectroscopically as well as theoretically. This is in sharp contrast to the ligand precursor, the N‐fused porphyrin, in which the HOMO–LUMO gap is affected by substituents in a similar manner to standard porphyrins and related macrocycles.
Chiral Phosphoric Acid‐Catalyzed Enantioselective Formal [3+2] Cycloaddition of Azomethine Imines with Enecarbamates
Authors: Wang Yang , Wang Qian , Zhu Jieping 
Published: May 2016

AbstractThe first catalytic asymmetric inverse electron demand 1,3‐dipolar cycloaddition of azomethine imines with enecarbamates has been developed. Isoquinoline‐fused pyrazolidines containing two or three contiguous stereogenic centers were obtained in high yields with excellent regio‐, diastereo‐, and enantioselectivities. The pyrazolidine ring can be opened to install an aminal, α‐amino nitrile, or homoallylamine function with an excellent control of the newly generated stereogenic center. Access to aminobenzo[a]quinolizidine is also documented.
Understanding Amyloid‐β Oligomerization at the Molecular Level: The Role of the Fibril Surface
Authors: Barz Bogdan , Strodel Birgit 
Published: May 2016

AbstractThe aggregation of the amyloid β‐peptide into fibrils is a complex process that involves mechanisms such as primary and secondary nucleation, fibril elongation and fibril fragmentation. Some of these processes generate neurotoxic Aβ oligomers, which are involved in the development of Alzheimer's disease. Recent experimental studies have emphasized the role of the fibril as a catalytic surface for the production of highly toxic oligomers during secondary nucleation. By using molecular dynamics simulations, we show that it is the hydrophobic fibril region that causes the structural changes required for catalyzing the formation of β‐sheet‐rich Aβ1‐42 oligomers on the fibril surface. These results reveal, for the first time, the molecular basis of the secondary nucleation pathway.
