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

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.

RSC Advances receives its first partial impact factor

24 Jun 2013

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.

Creative assemblies for targeted drug delivery

25 Apr 2013

Stimuli-responsive assemblies have generated a lot of interest in recent years especially in view of their biological applications. Enzyme-responsive assemblies for controlled drug release have gained particular interest as this offers potentially selective and targeted delivery of therapeutics.

A team of scientists from Nankai University (China) led by Yu Liu have fabricated a supramolecular assembly based on the host-guest complexation of amphiphillic calixarene with adenosine triphosphate (ATP). Complextion of the calixarene with ATP markedly lowers it’s critical aggregation concentration, forming hollow spherical nanoparticles. The nanospheres were shown to be responsive to phosphatase – an enzyme over-expressed in many tumor cells – and thus may have applications in drug delivery and cancer therapy.

Electron-conjugation facilitates electron transfer of hemoglobin by Ce(OH)3 nanorods

05 Apr 2013

Scientists from the University of Chinese Academy of Sciences (Beijing, China) led by Kebin Zhou investigated the interaction between nanorods of Ce(OH)₃ and CeO₂ and the redox protein hemoglobin.

The nano-bio interfaces, such as those between inorganic nanomaterials and biological systems, are gaining a significant amount of interest due to their importance in biomedical applications, but also out of concerns over the bio-safety of nano-engineered particles. In the case of ceria-based nanomaterials, some studies have found they were able to prevent the increase of reactive oxygen species (ROS) in vitro and in vivo due to the existence of Ce³⁺. However, others have found that some of these materials could actually generate ROS and cause toxicity to cells as Ce⁴⁺ is reduced to Ce³⁺.

In this work, Zhou and co-workers hydrothermally prepared Ce(OH)₃ and CeO₂ nanorods and studied their interaction with a typical redox protein hemoglobin through an electrochemical method combined with Electron Paramagnetic Resonance spectroscopy. Ce(OH)₃ was found to be more efficient in enhancing the direct electron-transfer of hemoglobin which may be due to the strong electron-conjugation interaction.
