Just Mix – Zeolitic Imidazolate Framework Synthesis

14 Oct 2014

By Iain Larmour, web science writer.

Iain Larmour is a guest web writer for ChemSci. He has researched a wide variety of topics during his years in the lab including nanostructured surfaces for water repellency and developing nanoparticle systems for bioanalysis by surface enhanced optical spectroscopies. He currently works in science management. In his spare time he enjoys reading, photography, art and inventing.

Zeolitic-imidazolate frameworks (ZIFs) are a sub-class of metal-organic frameworks (MOFs) with a wide range of potential uses including: CO2 capture, storage, catalysis, sensing and biomedicine. Unfortunately their synthesis often requires additives or reaction activation, and if they can be made without these it often requires long reaction times or results in low yields, neither of which is ideal for a substance with such wide potential uses.

To overcome this bottleneck in ZIF synthesis, Roland Fischer and his team from the Inorganic Chemistry department in Ruhr Universitat Bochum in Germany have developed a rapid room temperature synthesis approach. I am a great believer in developing approaches that can be carried out at room temperature and pressure and this is one such elegant solution. The authors produce nanocrystals of ZIFs in a very narrow size distribution by careful selection of the precursors and the solvents they are dissolved in. The solutions are then mixed and stirred to create the ZIF crystals; it really is that elegant.

ZIF crystals showing very narrow size distribution

The authors then used these crystals to fabricate thin films on quartz crystal microbalances and used this device to detect volatile organic solvents. This demonstration leads the way into exploring other uses of these ZIFs – after all, they can now be easily made. But to find out which solvent and precursors you need to use, you’ll have to read the paper today!

Ionic liquid-gas interfaces: more than a surface glance

13 Oct 2014

By Bethany Johnson.

Richard Massey writes about a hot ChemComm article for Chemistry World

Research by scientists in the UK suggests that small changes in the nature of binary ionic liquid systems can significantly alter their surface composition. The findings may aid the design of ionic liquid films for applications such as gas capture and supported catalysis, where surface adsorption is essential.

Studies on simple one-cation–one-anion mixtures have previously revealed that the outer layers contain a greater concentration of alkyl chains than in the bulk…

FBNCO: all the 2p-block elements in one molecule

Jennifer Newton writes about a hot ChemComm article for Chemistry World

Scientists in Italy have made a molecule with one of each of the 2p-block elements. Well, almost. There’s no neon in FBNCO but it would be a bit unfair to expect them to include an element with no known chemistry.

Assessing covalency in the hydrogen bond zoo

07 Oct 2014

By Bethany Johnson.

Jennifer Newton writes about a hot ChemComm article for Chemistry World

Covalency, a term describing bonding by sharing electrons, divides opinion when mentioned alongside hydrogen bonding. Worried that the concept of hydrogen bonding has been getting fuzzier over time, scientists in Germany have sought a fresh look at the very nature of these bonds, and how much covalency they involve.

Richard Dronskowski and colleagues at RWTH Aachen University collected evidence from hydrogen-bonded molecular crystals to elucidate how these crystals are held together and compare the covalency of long and short hydrogen bonds.

Antimalarial flow synthesis closer to commercialisation

11 Sep 2014

By Bethany Johnson.

Elisabeth Ratcliffe writes about a hot ChemComm article for Chemistry World

Scientists in Germany have demonstrated the large scale and inexpensive production of a range of antimalarial drugs, using a continuous flow system.

The processes yields several artemisinin-derived APIs that are key components in Artemisinin Combination Therapies

An important starting material for various anti-malarial drugs is artemisinin, which until recently could only be obtained by extraction from the plant Artemisia annua. As Peter Seeberger, from the Max Planck Institute for Colloids and Interfaces in Potsdam, explains, ‘the problem is that the drug is too expensive, such that in Africa and south east Asia between 40 and 50% of the artemisinin combination therapies are fake.’

Optimising multi-enzyme reactions – enabling enzymatic encoding

10 Sep 2014

By Iain Larmour, web science writer.

The ability to mimic cascade and linked enzyme reactions has potential applications for disease diagnosis and pharmaceutical manufacturing, to name just two. However, the optimisation of the ratios of the interacting enzymes can be a time consuming step when carried out using standard solution based enzyme assays. With the problem becoming exponentially more difficult with the number of enzymes in the system, Jun Ge and Zheng Liu of the Department of Chemical Engineering at Tsinghua University, with colleagues, have looked to overcome this hurdle by developing a simple, fast and high throughput method based on ink-jet printing.

The team replaced the colour inks in a standard inkjet printer with enzyme and substrate solutions. The ratio of these solutions could be controlled by varying the overall colour that was printed. Optimisation of cascade and coupled enzymatic reactions could be carried out rapidly and inexpensively compared to the standard solution based method.

Enzymatic encryption, decoding and deletion of information

Precise two-dimensional control of enzyme placement via ink-jet printing also raises the possibility of creating 2D codes with enzymatic encryption built in, as the figure demonstrates. I don’t want to give the secret of this encryption technique away so you’ll have to read the paper today.
