Themed Issue on Nanotechnology of Multifunctional Materials

Journal of Materials Chemistry C is planning to produce a themed issue on Nanotechnology of Multifunctional Materials in 2013. Please e-mail the editorial office at materialsC-rsc@rsc.org, if you are interested in contributing an article.

The Guest Editors of the issue will be Professor Fabio Biscarini (University of Modena and Reggio Emilia, Italy) and Dr Massimiliano Cavallini (Institute of Nanostructured Materials, CNR Bologna, Italy).

Molecular and polymeric multifunctional materials are relevant to many fields of technology, from optoelectronics, spintronics, information storage, magnetism, biosensing and energy production. They are designed to combine multiple properties and functional groups to control their self-organisation into a variety of supramolecular architectures. The technological control should not be limited to either the molecular level or in bulk, instead should span the different length scales. Devices require the control of size and position, and the integration of different materials.

The deadline for the receipt of manuscripts for this themed issue is 1 July 2013

Manuscripts can be submitted using the RSC’s online submissions service. Please clearly mark that the manuscript is submitted for the themed issue on ‘Nanotechnology of Multifunctional Materials’.

Please would you inform the editorial office by e-mail at materialsC-rsc@rsc.org as soon as possible if you plan to submit to the issue and whether your contribution will be original research or a review-type article. We would like to have a list of authors who intend to contribute as soon as possible.

Taking the shine off: Journal of Materials Chemistry A article in Chemistry World

Painting used to test method with a white dot to show test area (left). Test area before (middle) and after (right) cleaning

Painting restoration could be yet another application for ionic liquids, new research shows. The work paves the way to safer procedures for cleaning paintings.

Over time, varnish applied to the top of oil paintings tends to yellow and accumulate dirt. Current conservation methods involve cleaning paintings with organic solvents but these pose environmental and health risks. Now, researchers in Portugal have demonstrated that using ionic liquids is a less toxic way to remove varnishes from paintings.

Xinliang Feng wins the 2013 Journal of Materials Chemistry Lectureship

We are delighted to announce Professor Xinliang Feng has won the 2013 Journal of Materials Chemistry Lectureship.

Professor Feng is the fourth winner of the Journal of Materials Chemistry Lectureship. The Journal of Materials Chemistry Executive Editorial Board chose Professor Feng in recognition of the contribution he has made to the materials chemistry field.

Professor Feng will present the lectureship at ICMAT 2013 later this year and will be presented with the award by the Managing Editor of the journals Dr Liz Dunn.

Profesor Feng received his Bachelor’s degree in analytic chemistry from the China University of Geosciences in 2001. Then he obtained his Master’s degree in organic chemistry from Shanghai Jiao Tong University in March 2004, where he worked on the synthesis of fluorinated ion-exchange resins and polymer-supported organic catalysts. Later on he moved to Professor Herbert Mayr’s group at the University of Munich in April 2004 for a short period to conduct research on the nucelofugality and electrofugality in organic solvolysis. In September 2004, he joined the group of Professor Klaus Mullen at the Max Planck Institute for Polymer Research for a PhD thesis on the synthesis and supramolecular chemistry of novel polycyclic aromatic hydrocarbons, where he obtained his PhD degree in April 2008.

In December 2007, he was appointed as project leader at the Max Planck Institute for Polymer Research. And since 2011, he became an adjunct distinguished professor at the Shanghai Jiao Tong University and was appointed as the director for the Institute of Advanced Organic Materials.

His current scientific interests include the synthesis and self-organization of extended graphene molecules, novel conjugated oligomers and polymers, and testing for applications in organic electronic devices, processable graphene sheets for transparent electrodes and organic electronics, functional organic nanomaterials for energy oriented application, graphene-based 2D nanomaterials and low-dimensional nanostructured functional carbon-rich as well as hybrid materials for energy storage and conversion, 2D conjugated and supramolecular polymers for opto-electronic applications.

Hot Article: The reaction between Nafion sulfonyl fluoride precursor membrane and 1,4-dimethylpiperazine does not yield reliable anion-exchange membranes

Alkaline polymer electrolyte fuel cells (APEFCs) have received much attention as next generation, platinum free fuel cells for future energy applications. A significant challenge to the development of APEFCs is the fabrication of suitable anion-exchange membranes (AEMs) for use within the fuel cells.  Recently, a synthesis based on the reaction of Nafion® sulfonyl fluoride membranes with diamine 1, 4-dimethylpiperazine has been proposed as a method for making AEMs.

In this Hot Article, Varcoe and co-workers investigate the Nafion-based systems using a combination of vibration spectroscopy, solid state NMR and measurement of ion exchange capabilities.  They find strong evidence that membranes synthesised by the reported procedure are predominantly in the cation-exchange form. These findings suggest that, contrary to previous reports, the membranes are not suitable for use in electrochemical devices requiring anion exchange polymer electrolytes, such as APEFCs.

Hot Paper: Directed phase separation of PFO:PS blends during spin-coating using feedback controlled in situ stroboscopic fluorescence microscopy

Thin-films of semi-conducting polymers, which are used in the production of light emitting diodes (LEDs) and organic photovoltaic (OPV) devices, are commonly prepared by a spin coating method. The performance of these films is highly dependent on their final morphology; however understanding and exercising control over the formation of film morphologies has previously been challenging.

In this hot paper, Howse and co-workers used high speed stroboscopic fluorescence microscopy to observe directly the development  of phase separated structures in poly(styrene) and poly(9,9’-dioctylfluorene) blends during the spin-coating process. Their feedback-modulated spin coating technique enabled unprecedented control over the thin-film morphology, and presents a route towards increased efficiency in the manufacture of LED and OPV devices.
