Themed Issue on the Self-Organization of Nanoparticles: Call for Papers

Journal of Materials Chemistry is publishing a themed issue on the Self-Organization of Nanoparticles with Professor Nicholas A. Kotov (University of Michigan, USA) as the Guest Editor. The themed issue will collect a selection of the best papers in this area in a high profile and high impact themed issue which will be published in 2011. Please contact the Editorial Office if you are interested in contributing.

The deadline for the receipt of manuscripts for this themed issue is 17th April 2011.

Many scientists over the period of the last decade greatly contributed to the development and understanding of the self-organization phenomena involving inorganic nanoparticles.  Many of them result in truly amazing supramolecular systems transcending different scales of organization.  It is important to analyze now the progress and establish the most exciting directions of future research.

The issue will cover the most exciting directions in self-organized systems of nanoparticles. New examples of nanoparticle superstructures, experimental techniques to reach levels of complexity, electronic phenomena involving energy transfer and plasmonic effects in multiparticle systems, computational and theoretical methods of description of self-organization processes, technological prospects for self-organized systems, biological implications of nanoparticle ability to self-organize, new nanostructured materials utilizing self-assemble phenomena, collective behaviour in NP systems, and other topics related to the self-organization of nanoparticles constitute the intellectual framework of this issue.

The issue will contain communications, full papers and review-type articles (Feature, Highlights or Applications).  All manuscripts will be refereed in accordance to the standard procedures of Journal of Materials Chemistry, and in this respect invited articles will be treated in the same way as regular submissions to the journal.        

Manuscripts can be submitted using the RSC’s on-line submissions service. Please clearly mark that the manuscript is “submitted in response to the call for papers for the Self-Organization of Nanoparticles themed issue”.

Hot Article: Triazole–pyridine ligands: a novel approach to chromophoric iridium arrays

This ‘Hot’ paper describes the development of a novel click chemistry approach for the modular construction of tuneable multichromophoric light emitters. To make these iridium complexes, one, two or three triazole–pyridine units were effectively built into the heteroaromatic macromolecule using versatile acetylene- and azide-functionalised precursors.

Triazole–pyridine ligands: a novel approach to chromophoric iridium arrays

The approach described by the team from the Netherlands is of interest for the design and construction of various light-emitting materials by covalent linking of different chromophores, including versatile tuning of the material properties, using ‘click’ chemistry. One example of such an application was demonstrated; two iridium centres showing ‘yellow’ emission and one fluorene unit showing ‘blue’ emission were combined via the covalent linkage to provide a white-light emitter.

Hot Article: Enhancing the gas and energy storage properties of carbide-derived carbons

Activation of carbide-derived carbons: a route to materials with enhanced gas and energy storage properties  Thermal halogenation of a wide range of metal carbides provides a simple route to a class of so-called carbide-derived carbon (CDC) materials. The porosity of the CDCs, which is mainly in the microporous regime, may be modulated by the choice of metal carbide precursor and synthesis process, the maximum surface area achieved is only up to 2500 m2g−1, which limits their use in gas storage or in electrochemical capacitor applications that require larger surface areas.

This Highlight article is focused on what has and can be done to enhance the textural properties of CDCs via further post-synthesis treatments and the ramifications of such modifications on their gas/energy storage capacity. The main developments in physical and chemical activation of CDCs and consequences on gas and energy storage are summarised by the authors from the University of Nottingham, UK, and Instituto Nacional del Carbón, Spain.

Hot Article: Luminescent quantum-dot-sized semiconducting polymer nanspheres

In this ‘Hot’ paper, Mark Green and co-workers from Kings College, London report the synthesis of small luminescent conjugated polymer nanoparticles and the role of poly(ethylene glycol) in the nanoparticle structure.  This is the first time that semiconducting polymer nanospheres (SPNs) on the scale of quantum dots have been made using miniemulsion methods.

Luminescent quantum-dot-sized conjugated polymer nanoparticles—nanoparticle formation in a miniemulsion system

SPNs have been made using miniemulsion methods previously but the resulting materials have been significantly larger than quantum dots.  Quantum dots are desirable as these are the nanomaterial of choice for cell imaging.  The SPNs were characterized by TEM, absorption and emission spectroscopy, they were found to be stable in solution for months and bright and are expected to be effective in various fluorescence applications.

Hot Article: Acid-directed synthesis of SERS-active hierarchical assemblies of silver nanostructures

Acid-directed synthesis of SERS-active hierarchical assemblies of silver nanostructuresSurface-enhanced Raman scattering (SERS)-active silver hierarchical assemblies are synthesized in solution by the assistance of small acid molecules without using any polymer surfactant or capping agent. In this ‘Hot’ paper a team from China and the USA demonstrate the acid-directed self-assembly of metal nanoparticles (MNPs) into large systems with complex structures. They verify that small acid molecules (citric acid, mandelic acid, etc.) incorporated into conventional solution chemistry can direct the assembly of MNPs into well-defined hierarchical structures. The constructed assembled structures with highly roughened surfaces can be highly sensitive SERS platforms, and the fabricated core–shell Ag wires show especially high SERS sensitivity toward the analyte melamine.

Hot Highlight: Alloying and phase segregation of gold-platinum nanoparticles

Gold-platinum nanoparticles: alloying and phase segregation This report by Chuan-Jian Zhong and co-workers at the State University of New York at Binghamton highlights recent insights into the nanoscale phase properties of gold-platinum (AuPt) nanoparticles.  The alloying and phase-segregation of supported AuPt nanoparticles depend on a combination of size, composition, and preparation parameters.  This system serves as an example to shine a light on the importance of changes in physical and chemical properties in which nanoscale multimetallic materials may differ from their bulk counterparts.

Hot Feature Article: The many nanoscale structures of polyaniline produced from aniline oxidation

The oxidation of aniline to produce “polyaniline”: a process yielding many different nanoscale structuresThe number of different nano- and micro-scale structures produced from the chemical oxidation of aniline into “polyaniline” is rivalled by few other organic materials.  Small and subtle changes in reaction parameters during aniline oxidation result in nanoscale structures such as tubes, flowers and even those resembling anatomical organs and sea animals!  A nanomaterial’s properties are highly dependent on its morphology so understanding polyaniline’s propensity for forming these structures is crucial towards tailoring the material for different applications as well as improving its synthetic reproducibility.

This ‘Hot’ Feature Article by Henry D. Tran from Fibron Technologies Inc. and Richard B. Kaner and co-workers from the University of California Los Angeles examines these different structures and the small and subtle changes in reaction parameters that result in their formation.  They discuss some of the highly debated aspects of these processes and give their perspective on where things are headed in the years to come.
