Polymorphism – what it is and how to identify it

21 Aug 2013

The field of polymorphism is an area of growing importance, and the discussions around it and related terms are still on-going in the area of crystal engineering.

Here, Katharina Fromm and colleagues from the University of Fribourg, Switzerland look at the historical development of the definition of polymorphism. This systematic review provides discussion of polymorphism as it relates to different classes of compounds: elements, inorganic compounds and organic and organometallic compounds with chosen examples.

Look out for the three schematic flow diagrams included in the conclusions as useful tools for determining polymorphism for each class of compounds.

Tiny 3D frog hydrogel scaffolds

01 Aug 2013

By Mary Badcock, Deputy Editor.

Researchers in Austria have made these three-dimensional hydrogel scaffolds in the shape of tiny frogs. The frogs help demonstrate the efficacy of new water-soluble photoinitiators, developed by Robert Liska from Vienna University of Technology and colleagues, for fabricating micrometre-sized hydrogels quickly in complex, predesigned shapes.

Water soluble catalysts for pharmaceutical intermediates

22 Jul 2013

By Sara Coles, Guest Web-Writer.

Sara Coles is a guest web-writer for RSC Advances. She currently works for Johnson Matthey in Royston, UK.

Jiahong Li and colleagues at Chengdu Institute of Organic Chemistry in China have prepared water-soluble ligands to allow transition metal catalysed asymmetric transfer hydrogenation (ATH) of aromatic ketones, especially aromatic ketones with a bromine group in the alpha position. They produced the expected alcholos with ees up to 96% and the catalyst could be reused at least 21 times.

The reactions were carried out in the presence of cationic surfactant CTAB (cetyltrimethylammonium bromide). Of the three catalytic metals tested, ruthenium, iridium and rhodium, they report that the best results were obtained using ruthenium.

Products synthesised using the novel catalyst system included key pharmaceutical intermediates for anti-asthma drugs, terbutaline and salbutamol.

RSC Advances receives its first partial impact factor

24 Jun 2013

By Mary Badcock, Deputy Editor.

Since its launch, RSC Advances has reached many major milestones. From the publication of the first issue back in August 2011 to publishing its 2000^th article in November 2012 – RSC Advances has been continually moving from strength to strength.

This month sees the Journal reach another significant milestone – achieving its first impressive partial impact factor of 2.562.*

RSC Advances front cover Why is it a partial impact factor? To explain, the impact factor provides an indication of the average number of citations per paper, calculated by dividing the number of citations in a year by the number of citeable articles published in the preceding two years. The number of citeable articles that the RSC Advances 2012 impact factor is based on is only 233, from the nine issues of Volume 1 published in August – December 2011.

Professor Mike Ward, Chair of the RSC Advances Editorial Board, comments “We are very pleased to announce the first partial impact factor of 2.562 for RSC Advances. This is an excellent start and illustrates that RSC Advances is making itself noticed in the chemistry community: it is not just highly popular amongst authors – having grown from monthly to weekly issues in less than two years – but contains good quality work that is being noticed by others. The important point is that this partial IF is based on citations to papers published in 2011. As RSC Advances only started in mid-2011 the sample size is therefore small.

We are grateful to all of our authors – and those who have cited their work! – for this encouraging start and look forward to greater things in the future.”

With increased visibility of the articles published in RSC Advances the number of citations to the Journal is growing rapidly every week, a reflection of the high quality research being published in the Journal.
