From chip fat to biofuel

15 Jul 2015

Researchers from Singapore and China have developed a cheap and green catalytic system for turning fatty acids into fuel that doesn’t require hydrogen or a solvent.

Hydrocarbon biofuels made from waste fats and oils, such as leftover cooking oil could help reduce our dependence on fossil fuels. Traditionally, these biofuels are synthesised by transesterifying lipids under harsh alkaline conditions; in addition to generating waste solvent, this technique does not remove enough oxygen, so the products are incompatible with diesel engines. The process also doesn’t work with fatty acids as they become soapy and deactivate the catalyst. Read the full article in Chemistry World»

Bread leavening proves useful for energy storage

14 Jul 2015

Just like bread, hierarchically porous carbons (HPCs), are judged on their texture; so researchers in China have called on their baking know-how to cook up a sustainable method for producing these supercapacitor components.

HPCs could prove useful in energy storage because of their high surface area and short ion transport pathway. But existing synthetic methods for producing HPCs, including nanocasting and soft-templating, are unfeasible for industrial application as they require complex, expensive processes.

Green Chemistry Strategies for Drug Discovery

13 Jul 2015

It is rapidly becoming clear that by incorporating green chemistry techniques earlier in drug development, pharmaceutical companies can greatly speed the production of a drug candidate.

Integrating green chemistry protocol into the drug discovery discipline is a relatively new phenomenon, as the scale at which chemists operate in drug discovery is smaller than in process and manufacturing chemistry.

Written by experts pioneering green chemistry efforts within their own institutions, Green Chemistry Strategies for Drug Discovery provides a practical guide illustrating to both academic and industrial labs how to implement greener process approaches for the greatest return on their investment, and without slowing down their science.

The Editors have taken a comprehensive approach to this emerging field, covering the entire drug discovery process from molecule conception, through synthesis, formulation and toxicology, with specific examples and case studies where green chemistry strategies have been implemented. They also address cutting-edge topics like biologics discovery, continuous processing and intellectual property.

Green Chemistry Strategies for Drug Discovery is the newest publication in the RSC Drug Discovery series. Further details on the content and scope of this book can be found on its Books Publishing page. If you like what you read, Green Chemistry Strategies for Drug Discovery is available now as a hardback from our Royal Society of Chemistry Bookshop. It is also in our 2015 eBook collection.

Ionic liquid a perfect fit for rare earth recycling

27 Mar 2015

Chemists in Belgium have shown how an intriguing ionic liquid they developed 10 years ago can recover valuable rare earth metals from stockpiles of used fluorescent lamps and magnets.

Rare earth metals are important in high tech applications, but China controls most of the world’s dwindling supply, periodically setting export quotas and driving up prices. They occur naturally elsewhere, but new production is time consuming and costly to establish.

: It is estimated that by 2020 stockpiled lamp phosphor waste will contain around 25,000 tons of rare earths

Shrimp shells to mine uranium from the ocean

07 Mar 2014

Shrimp shells that would otherwise be thrown away by the seafood industry have been turned into tough fibres that can harvest valuable metals from water.

Robin Rogers, and his team at the University of Alabama in the US, had long been interested in using ionic liquids to process cellulose but the Deepwater Horizon oil spill in 2010 encouraged them to try something similar with chitin, the structural biopolymer that makes up the shells of various crustaceans. ‘We started working with the Gulf Coast Agricultural and Seafood Co-Op in Bayou La Batre, looking at uses for their shrimp shell waste, about the same time as the moratoriums on shrimping. It was quite clear that new products and profits were needed.’
