ChemPlusChem 4/2015: Applications in Medicine
Reseach with potential medicinal applications, in the broadest sense, set an unexpected accent in this issue. Narinder Singh reports the nanomolar detection of iodine in aqueous medium and also in urine samples based on the selective recognition behavior of a gold--organic nanoparticle sensor. Chelator-appended cyclodextrin derivatives devised by Gzaziella Vecchio show potential for the treatment of metal-associated neurogenerative diseases. In the research featured on the front cover Giuliano Giambastiani prepared a hetero-bifunctional cross-linker to decorate carbon nanotubes; these in turn can act as nanocarriers for potential biological probes (cover profile).

- Titanium Dioxide/Graphene Oxide Nanocomposites as Heterogeneous Catalysts for the Esterification of Benzoic Acid with Dimethyl Carbonate
Durairaj Santhakumar Ruby Josephine, Balasubramanian Sakthivel, Prof. Kunjithapatham Sethuraman and Prof. Amarajothi Dhakshinamoorthy
Article first published online: 27 APR 2015 | DOI: 10.1002/cplu.201500080
Cat. performance: Different loadings of titanium dioxide nanoparticles on sheets of graphene oxide (GO) provided a series of TiO2/GO nanocomposites and their activity was evaluated for the esterification of benzoic acid using dimethyl carbonate as a green methylating agent. The catalytic activity of the 5 wt % TiO2/GO nanocomposite was superior to that of GO, TiO2, and TiO2 on other supports.

Optimizing MINTs. The reaction conditions for the synthesis of mechanically interlocked derivatives of single-walled carbon nanotubes (MINTS, see figure) were varied systematically. Analysis of the macroscopic data helps shed light on the mechanism of formation of MINTs.

Leave your coat on: Benzoxazine derivatives based on phenolated methyl oleate and either aniline, 1,6-diaminohexane, or 4,4′-diaminodiphenylmethane are the basis for dense, hydrophobic coatings on Zn-Mg-Al alloy coated steel for passive corrosion protection. The polymer coatings invoke a substantial anodic shift of the open-circuit potential and the breakthrough potential in potentiodynamic measurements (see figure).
- Reduced Graphene Oxide Composite with Oxidizable Manganese/Cobalt Mixed Oxide for p-Cresol Oxidation by Using Molecular Oxygen
Dr. Ajay Jha, Sagar H. Patil, Bhanu P. Solanki, Dr. Ana P. C. Ribeiro, Prof. Carlos A. N. Castro, Dr. Kashinath R. Patil, Prof. Alberto Coronas and Dr. Chandrashekhar V. Rode

Composite doubles: A reduced graphene oxide (r-GO) composite with MnCo oxide nanoparticles increases the selective oxidation of p-cresol to form p-hydroxybenzaldehyde (PHBAld; see scheme, PHBAlc=p-hydroxybenzyl alcohol). The high catalytic activity of the r-GO–MnCo catalyst is related to the increase in the redox potential of the mixed oxide after being supporting on r-GO.

Flaking out: La2Se3 nanoflakes were prepared from an aqueous medium by means of a chemical-bath deposition method and then used as a supercapacitor electrode (see figure). An asymmetric supercapacitor device based on the La2Se3 electrode in aqueous electrolyte exhibited good specific capacitance, excellent charge/discharge properties, and superior long-term cycling stability.
