      The cover picture shows the growth mechanism of Cu2O/noble-metal nanocomposites and the application of these nanocomposites as surface-enhanced Raman scattering (SERS) substrates, as reported by Z. Wang and co-workers in their Full Paper on page 684 ff. They aim to synthesize SERS substrates with high sensitivity and good reproducibility for the detection of food contaminants.

      The frontispiece shows a Eucalyptus tree, the leaves of which contain an oil mainly consisting of a bicyclic terpenoid, 1,8-cineole, nearly unused as an intermediate in chemical synthesis owing to its stability and symmetrical structure. Nomenclature uncertainties and varied numbering of carbon atoms in the literature have sometimes obscured the development of its chemistry. This Review by Robert Azerad on page 634 ff. reports a unified numeration system and constitutes an exhaustive compilation of the physicochemical characteristics of sixty derivatives, their structural and synthetic studies, biological activities, and biotransformations in microorganisms, plants, and animals such as eucalyptus-leaf-eating Australian marsupials.

      In the wings: A bis-phenolate with calixarene character influences the orientation of Jahn–Teller axes (shown by arrows in the figure) in a tetranuclear MnIII cluster. Structural changes and prevailing magnetic properties are presented.

    4. Understanding the Photochemical Pathway of In Vitro Target Delivery of Aluminium Phthalocyanine: A Mechanistic Approach Using Radical Reaction Chemistry (pages 671–679)

      Victor Akpe, Dr. Erik Vernet, Dr. Christian Madu, Dr. Joseph C. Obirai and Prof. Dr. Hjalmar Brismar

      Article first published online: 11 MAR 2014 | DOI: 10.1002/cplu.201300402

      Thumbnail image of graphical abstract

      Stain removal: The photochemistry of aluminium phthalocyanine (AlPc) and its use in chromophore-assisted laser inactivation has been studied in cell-free and cell-based systems. In the former system, the photosensitiser recovers its fluorescence signal through a reversible photobleaching–phosphorescence process (see figure). In the cell-based system, photoactivation of antibody-conjugated AlPc results in irreversible loss of fluorescence signal.

      The cube root: Cu2O[BOND]Au and Cu2O[BOND]Ag nanocomposites have been synthesized through an in situ wet-chemical reduction route with Cu2O nanocubes as both substrate and reducing agent. The composites serve as effective surface-enhanced Raman scattering substrates (see figure).

    2. Flexible Janus Nanofibers: Facile Electrospinning Construction and Enhanced Luminescent–Electrical–Magnetic Trifunctionality (pages 690–697)

      Dr. Nan Lv, Qianli Ma, Prof. Xiangting Dong, Assoc. Prof. Jinxian Wang, Dr. Wensheng Yu and Guixia Liu

      Article first published online: 18 MAR 2014 | DOI: 10.1002/cplu.201300404

      Thumbnail image of graphical abstract

      Two-faced fibers: Flexible Janus nanofibers with enhanced luminescent–electrical–magnetic trifunctionality have been successfully fabricated (see picture). The unique structure allows the isolation of Fe3O4 nanoparticles (NPs) and polyaniline (PANI) from [Tb(ba)3(phen)] (ba=benzoic acid, phen=1,10-phenanthroline), resulting in weaker light absorption of Fe3O4 NPs and PANI, and strong luminescence of the nanofibers.

      Article first published online: 18 MAR 2014 | DOI: 10.1002/cplu.201300424

      Thumbnail image of graphical abstract

      Extra support: Core–shell-structured magnetic nanocatalysts have been prepared and used as efficient heterogeneous catalysts for the aerobic oxidation of styrene. Mildly reduced graphene oxide (MRGO; see picture)/Fe3O4@C–salen–Co showed over 91 % conversion of styrene and over 52 % selectivity to the styrene oxide.

    7. Helical Carbon Segment in Carbon–Boron–Nitride Heteronanotubes: Structure and Nonlinear Optical Properties (pages 732–736)

      Rong-Lin Zhong, Dr. Shi-Ling Sun, Dr. Hong-Liang Xu, Prof. Yong-Qing Qiu and Prof. Zhong-Min Su

      Article first published online: 19 MAR 2014 | DOI: 10.1002/cplu.201300381

      Helix topological effect: The helix C segment in HA-9 leads to fascinating long-range charge-transfer character. As a result, the β0 value of HA-9 is 1.80×104 a.u., which is clearly larger than that of PA-9 (4.99×103 a.u.). Further investigations show that the larger β0 value of HA-9 is essentially induced by the helix topological effect of the C-segment (see figure).

      Visible photocatalysis: N-doped TiO2, synthesized through a simple ammonia-modified hydrolysis-solvothermal process, exhibits high visible photocatalytic activities for the degradation of acetaldehyde and phenol. The photocatalytic activity is further enhanced upon increasing the O2 adsorption through phosphate modification (see figure).

    9. Effect of Aluminum Doping on the Growth and Optical and Electrical Properties of ZnO Nanorods (pages 743–750)

      Ruiqiang Chen, Dr. Pengli Zhu, Libo Deng, Tao Zhao, Prof. Rong Sun and Prof. Chingping Wong
