Division’s programming, Professor Sherine Obara and Professor Rafael Luque brought together a number of scientists in a symposium focused on the merits of green chemistry for a sustainable future. The symposium, entitled “Green Chemistry and the Environment” offered a broad and multifaceted view on employing sustainable methods for green chemistry goals. Green Chemical methods and sustainable processes can offer remarkable possibilities for academia and the chemical industry in our aim to improve the environmental footprint of materials, chemicals and fuels processing and manufacturing. This issue of ChemSusChem contains some of the work presented at the the symposium. Oliver Kappe et al. (University of Graz) report on the singletoxygen oxidation of 5-hydroxymethylfurfural in continuous flow, in their Communication on page 1648 (DOI: 10.1002/ cssc.201403182). This interesting contribution couples the sustainability merits of flow-chemistry process with the exciting area of renewables, describing the conversion of 5-hydroxymethylfurfural into the polyester precursor 5-hydroxy-4-keto-pen-

Editorial tenoic acid. The procedure is scalable and applicable to related biobased furfurals. Csaba Janky (University of Szeged), Krishnan Rajeshwar (University of Texas at Arlington), and co-workers report in a Full Paper on page 1652 on the synthesis (by combustion methods) of binary tungstate nanoparticles, and their photocatalytic activity (DOI: 10.1002/cssc.201500383). The influence of the tungsten precursor on the product is of particular relevance, as each sample’s photocatalytic activity is benchmarked against a commercial oxide sample, obtained by solid-state ceramic synthesis. Christophe Len and Murielle Billamboz (Universit¦ de Technologie de CompiÀgne) report on the activation of pinacol couplings in emulsified water, and the role played by the surfactant in their Full Paper on page 1664 (DOI: 10.1002/ cssc.201500108). The rate and selectivity of the reductive C¢C coupling are compared under three different activation technologies. The use of a neutral surfactant results in successful conversion of aromatic or a,b-unsaturated aliphatic carbonyl compounds in moderate to excellent yields. An insight into the reaction mechanism is also given, with this protocol being able to provide an innovative approach to coupling chemistries in aqueous media. Juan Colmenares et al. (Institute of Physical Chemistry, Warsaw) report on the sonophotodeposition of palladium– gold photocatalysts on titania in their Full Paper on page 1684 (DOI: 10.1002/cssc.201403125), and employ these catalysts in the oxidation of methanol to methyl formate.

odology that can be used to prepare well-defined bimetallic surfaces on semiconductor supports for catalytic applications. Finally, on page 1694, Carol Lin et al. (City University of Hong Kong) discuss the potential of lipids derived from foodwaste and algal biomass (produced from food-waste hydrolysate) for the formation of plasticizers and surfactants in a Communication (DOI: 10.1002/cssc.201402888). Plasticizers are formed by epoxidation of double bonds of methylated unsaturated fatty acids with in situ-generated peroxoformic acid, while surfactants are formed by transesterification of saturated and epoxidized fatty acid methyl esters (FAMEs) with polyglycerol. Such waste/biomass engineered products have a significant potential to replace current petroleum-derived analoges with improved biocompatibility and a reduced environmental footprint. It is hoped that the results presented herein, ranging from biomass/waste valorisation, greener catalytic protocols, and benign-by-design syntheses of materials to continuous-flow oxidations, can serve as starting point for further innovations in sustainability. The Guest Editors of this special issue look forward to enjoying further improvements in the aforementioned topics and fields related to Green Chemistry and Sustainability and hope these contributions can encourage other researchers to advance in such topics in our dream towards a more sustainable global future.
