Porous aromatic frameworks

27 Jul 2012

By Jennifer Newton, Publishing Editor.

This article is HOT as recommended by the referees. And we’ve made it free to access for 4 weeks.

Teng Ben and Shilun Qiu discuss porous aromatic framework network formation and the relationship between secondary building units and function in this hot Highlight article. The ability to control the pore size in porous aromatic frameworks lends itself to numerous applications, including in molecular separation, catalysis, photoelectric materials, clean energy and carbon dioxide capture and storage.

Hydrogels for studying biomineralisation

23 Jul 2012

By Helen Lunn, Publishing Editor.

This article is HOT as recommended by the referees. And we’ve made it free to access for 4 weeks.

Hydrogel-based double-diffusion systems for studying biomineralization

This Highlight presents an overview of hydrogel-based double-diffusion systems to study biomineralization. The authors describe two types of diffusion systems: static and dynamic. They evaluated four such systems to design an optimized system taking into account the type of hydrogel, the boundary conditions and design strategy.

Gels represent a good model to study and understand biomineralization because the mineral deposition that occurs in many mineralization processes in vivo takes place in gelling environments; however, they are not often used due to their complexity and poor knowledge of ionic diffusion.

Facile, economical and magnetically recoverable photo-Fenton’s reagent

20 Jul 2012

By Matthew Cude, Development Editor.

Zhijun Luo, Xiangyang Wu et al. have recently developed a facile one-step route to generate magnetite/carboxylate-rich carbon spheres exhibiting excellent photodegradation properties, without the need of H₂O₂ or UV light.

Wastewater can contain many contaminants including a wide range of organic material; the photo-Fenton reaction is a highly efficient way to oxidise these pollutants using Fe³⁺, H₂O₂ and UV light to generate^.OH radicals.

The materials reported here are highly water-dispersible, easy to make and operate under visible light across a wide pH range. The magnetite/carboxylate-rich carbon spheres can also be recovered magnetically making this a convenient reaction to use.

July Crystal Clear: Crystal Cavern

12 Jul 2012

By Matthew Cude, Development Editor.

An image taken through an optical microscope of L-arginine acetate grown using a 'Metal-Assisted and Microwave-Accelerated Evaporative Crystallization’ process.

The beautiful image in this month’s crystal clear isn’t actually a crystal cavern. It is crystals of L-arginine acetate grown using a new crystallisation technique. The crystals are of particular interest in non-linear optics given their second harmonic generation properties.

The Aslan Research Group have developed a new crystallisation method to grow L-arginine acetate crystals much faster than the previously reported cooling/evaporation method. The ‘Metal-Assisted and Microwave-Accelerated Evaporative Crystallization’ process uses silver island films and low power microwave heating to grow the crystals quickly. The team also investigated functionalising the metal nucleation surface to see if this enhanced crystal growth.

The image shown here is of the crystals created using bare silver island films and microwaves, the rest of the teams results, including full details of their growth process can be found in Issue 14 of CrystEngComm.

Competing cocrystals: Hydrogen-bonding vs. Halogen-bonding

05 Jul 2012

By Matthew Cude, Development Editor.

This article is HOT as recommended by the referees. And we’ve made it free to access for 4 weeks.

Tomislav Friscic and colleagues report a cocrystal system that bonds by either hydrogen or halogen bonding depending on the stoichiometric ratio of the two components of the crystal. Interactions within crystal structures such as hydrogen bonding, ionic bonds, van der Waals forces and pi-interactions determine a material’s structure and properties.

Understanding these interactions and engineering crystals with specific structures is important, the ability to switch the interaction between hydrogen and halogen bonds by altering the ratio of molecules is an interesting discovery and helps establish the role halogen bonds play in molecular self-assembly.

CrystEngComm impact factor released!

03 Jul 2012

By Matthew Cude, Development Editor.

The 2011 Journal Citation Reports ® (Thomson Reuters, 2012) have been released and CrystEngComm has received a 5 year impact factor* of 4.02 and an Immediacy Index** of 0.844, the highest Immediacy Index for any crystal engineering journal!

We would like to thank all our authors, readers and referees who have contributed towards this success. Our thanks also go to our Editorial and Advisory Board Members and our Associate Editors for all their hard work and dedication to the journal.

A full list of RSC successes can be found at the RSC Impact Factor release.

For more information about CrystEngComm, including how to submit your research, check out the journal homepage.

*A 5-year impact factor is the average number of times articles from a journal published in the past five years have been cited in the JCR year. It is calculated by taking the number of citations in the JCR year to articles published in the preceding 5 years and dividing by the number of articles published in the previous 5 years.

** The Immediacy Index is a measure of how topical and urgent work published in a scientific journal is. It is measured by dividing the number of citations made to articles in a journal in a given year by the number of citeable articles published in the journal for the same year.
