Nanorods in minutes

PbSe nanorods have been successfully made by solution–liquid–solid (SLS) growth of PbSe nanocrystals. This growth was followed by oriented attachment of adjacent PbSe nanoparticles. The team from South Korea who carried out this synthesis used Bi catalysts dispersed in the precursor solution to make these nanocrystals thereby reducing the time and temperature taken to produce them.

Hot Article: Doping scintillation crystals

Cerium is an interesting element for luminescence, however only Ce3+ ions give rise to fast luminescence because the charge transfer transition in Ce4+ is spin-forbidden. Ce-doped lutetium scandium orthoborate (Lu0.8Sc0.2BO3:Ce) has potential application in gamma-ray detection and in this Hot Article by Yuntao Wu and Guohao Ren et al. (Shanghai Institute of Ceramics, Chinese Academy of Sciences) the oxidation state of the Ce ions is investigated.

The study on single crystals of Lu0.8Sc0.2BO3:Ce utilizes XANES based on new generation synchrotron radiation. The research team were able to discover the influence cerium doping has on the luminescence mechanism and the type of point defect in Lu0.8Sc0.2BO3:Ce crystals.

This Hot Article is free to access for 4 weeks and you can keep up to date with the latest news in crystal engineering by liking us on facebook, following us on twitter or signing up to our e-alert service!

January Crystal Clear: Evolution of a cube

This months Crystal Clear shows a near perfect rhombic dodecahedron from Janosch Cravillon, Michael Wiebcke and colleagues at the Leibniz Universitat Hannover in their article published in Issue 2 of CrystEngComm.

The team have investigated crystal morphology of a zeolitic imidazolate framework (ZIF-8) using a solvothermal synthesis in methanol solvent. By modulating the crystallisation process using a simple monodentate ligand they were able to study the crystal morphology with time, discovering via intermediate steps the initially cubic crystals become rhombic dodecahedra as displayed in this striking SEM image.

You can see the team’s images of the crystal evolution and read their findings on modulation and the parameters which affect it in their paper below.

Formate modulated solvothermal synthesis of ZIF-8 investigated using time-resolved in situ X-ray diffraction and scanning electron microscopy

DOI: 10.1039/C1CE06002C

If you’re interested in zeolitic imidazolate frameworks there is also this article on the application of ZIF-9 in catalysis. (All articles in Catalysis Science & Technology are free to access for the duration of 2012).

HOT Paper: Exploring co-crystals to increase efficacy of HIV drug

Co-crystallisation of nevirapine with maleic acid lead to around a fivefold increase in the aqueous solubility of the drug.

Co-crystallisation of nevirapine with maleic acid lead to around a fivefold increase in the aqueous solubility of the drug.

Mino Caira and colleagues have created co-crystals of nevirapine (an antiretroviral drug) with maleic acid that could improve the aqueous solubility of the drug.  Their success was a result of exploiting several hydrogen-bonding functionalities in nevirapine, in particular (but not exclusively) its rigid amide group.

Read their paper to find out more – its currently free.

Co-crystals of the antiretroviral nevirapine: crystal structures, thermal analysis and dissolution behaviour

Hot Highlight: Porous organic molecular materials

Metal–organic frameworks are materials containing coordination bonds between organic linkers and metal ions or clusters, exclusion of guest molecules in the structure can create a highly porous material with potential for gas storage, gas separation or catalysis. Other well studied nanoporous materials include zeolites, metal oxide molecular sieves, silica gels, activated carbons, covalent organic frameworks and organic network polymers.

This highlight from Jian Tian, Praveen K. Thallapally and B Peter McGrail from Pacific Northwest National Laboratory reviews a very different class of nanoporous material, those comprised entirely of discrete organic molecules containing only weak non-covalent interactions. Often there is very close packing in the crystals (with voids or channels rarely exceeding 25 Angstroms) but under the right conditions solvents can be included within the structure in zero, one, two or three dimensional solvent accessible voids.

If the solvent can be easily removed from the structure highly porous crystalline materials can be made  from organic compounds, the difficulty however is that upon desolvation the crystals often collapse into closely packed structures. This review discusses a wide range of structures which have been found to be stable as porous organic molecular materials, including crystalline structures with voids and amorphous solids with interconnected disordered pores. Read the CrystEngComm Hot Article (which is free to access for 4 weeks) for more details.

2012 GRC on Crystal Engineering

Christer Aakeroy, co-Vice Chair of the GRC

The 2012 GRC on Crystal Engineering is taking place this year from June 10-15, 2012 at Waterville Valley Resort, NH, USA. This GRC will be chaired by Robin Rogers, with co-Vice-Chairs Mike Zaworotko and CrystEngComm Associate Editor, Christer Aakeroy. The meeting will also include a new and exciting Gordon Research Seminar (GRS) in which only students and postdocs may present or lead discussions.  More information is available on the GRC website.

The 2012 GRC on Crystal Engineering follows the highly successful first ever GRC on Crystal Engineering (2010) which had over 160 international participants. Read about my experience at the excellent 2010 GRC in this editorial.
