New drug delivery method for ibuprofen examined

French scientists have prepared silica microspheres containing the commonly used drug ibuprofen using a spray drying and sol-gel process. The team found that the ibuprofen forms separate nano-domains within the silica microspheres.

For the full details about the properties of these fascinating materials read the PCCP article today:

Call for papers: Spectroscopy and dynamics of medium-sized molecules and clusters

PCCP themed issue:
Spectroscopy and dynamics of medium-sized molecules and clusters
Guest Editors: Majdi Hochlaf, Roberto Linguerri (Université Paris-Est) and David Lauvergnat (CNRS)

PCCP is delighted to announce the high-profile themed issue on Spectroscopy and dynamics of medium-sized molecules and clusters: Theory, experiment and applications. It is our pleasure to invite you to submit to this themed issue.

The themed issue will be published in PCCP in summer 2013 and will be promoted to the community throughout the year to maximise the visibility of the work published.

Deadline for Submissions: 21 January 2013

This themed issue will tackle new and still unresolved challenges in molecular science with particular emphasis on experimental and theoretical spectroscopy and/or quantum dynamics. One of the principal topics is the treatment of anharmonicity in medium-sized molecules and clusters.

Applications include, for instance, accurate description of highly excited states of molecules (including electronic, vibrational and rotational excitation), weakly bound aggregated systems, dynamics of molecules undergoing conformational changes, dynamics of molecules adsorbed on nanostructures, molecules at cold and ultracold temperatures, molecules in unusual environments (e.g., interstellar space), atmospheric molecules and long-range particle transfers.

It is envisaged that articles in the themed issue will discuss different approaches to overcome the difficulties associated with the numerical treatment of anharmonicity in complex molecular systems. In addition, there will be articles exploring new experimental techniques devoted for the investigation of such systems beyond the harmonic approximation and beyond the Franck-Condon principle. The proposal of new strategies and the combination of existing approaches which deal with the analysis and interpretation of recent experimental studies of highly excited molecular systems and astrophysical observations are welcomed.

We hope you can take part in this exciting issue.

With our best wishes,

Majdi Hochlaf, Roberto Linguerri and David Lauvergnat
Guest Editors

Jane Hordern
Deputy Editor, PCCP

ISOS-3 inter-laboratory collaboration: OPV device stability

This ‘HOT’ paper just published in PCCP results from a large international collaboration across 14 different institutes, and resulted from the 3rd International Summit on Organic Photovoltaic Stability (ISOS-3).

The paper is a systematic TOF-SIMS study of the degradation behavior of six different organic photovoltaic (OPV) devices degraded under three different experimental conditions.

This study highlights the advantage of combining analysis techniques to systematically assess OPV devices. The results of this investigation and previous reports shed new light on OPV stability and is a step towards the large scale application of organic solar cells.

Read the ‘HOT’ PCCP article:

Call for papers: Very hard x-rays and the frontiers of materials chemistry

PCCP themed issue: Very hard x-rays and the frontiers of materials chemistry
Guest Editor: Mark A. Newton (ESRF, France)

PCCP is delighted to announce the high-profile themed issue ‘very hard x-rays and the frontiers of materials chemistry’. It is our pleasure to invite you to submit to this themed issue.

The themed issue will be published in PCCP in spring 2013 and will be promoted to the community throughout the year to maximise the visibility of the work published.

Deadline for Submissions: 03 December 2012

Application of hard X-rays (>30 keV) to fundamental and industrially applicable materials chemistry, covering length scales from the atomic to the long-range. Our emphasis will be on in-situ and time-resolved studies in demanding sample environments: catalysts, synthesis, fuel cells, gas storage, battery materials and operation: though this is not to rule out more traditional solid state structural chemistry wherein very hard X-rays, and their potential crossover with neutron studies, leads to a number of new possibilities and/or more profound insight into the structure/function of a range of materials.

This themed issue will take a holistic view of capabilities/resources currently available worldwide, and aim to showcase what may be achieved using them. This is a rapidly developing area which we believe will be of great interest to the communities involved.

Submission details:

  •  Manuscripts can be submitted in any reasonable format using our online submissions service
  • Submissions should be high quality manuscripts of original, unpublished research
  • Communications and full papers can be submitted for consideration, which will be subject to rigorous peer review
  • Please indicate upon submission that your manuscript is intended for this themed issue
