Alexandre Pépin's insight:

In an effort to create a more viable material for drug delivery, a team of researchers has accidentally created an entirely new material thought for more than 100 years to be impossible to make. Upsalite is a new form of non-toxic magnesium carbonate with an extremely porous surface area which allows it to absorb more moisture at low humidities than any other known material. "The total area of the pore walls of one gram of material would cover 800 square meters (8611 sq ft) if you would 'roll them out'", Maria Strømme, Professor of Nanotechnology at the Uppsala University, Sweden tells Gizmag. That's roughly equal to the sail area of a megayacht. Aside from using substantially less energy to create drier environments for producing electronics, batteries and pharmaceuticals, Upsalite could also be used to clean up oil spills, toxic waste and residues.

Scientists have long puzzled over this particular form of magnesium carbonate since it doesn't normally occur in nature and has defied synthesis in laboratories. Until now, its properties have remained a mystery. Strømme confesses that they didn't actually set out to create it. "We were really into making a porous calcium carbonate for drug delivery purposes and wanted to try to make a similarly porous magnesium carbonate since we knew that magnesium carbonate was non-toxic and already approved for drug delivery," she tells us. "We tried to use the same process as with the calcium carbonate, totally unaware of the fact that researchers had tried to make disordered magnesium carbonates for many decades using this route without succeeding."

The breakthrough came when they tweaked the process a little and accidentally left the material in the reaction chamber over a weekend. On their return they found a new gel in place. "We realized that the material we had made was one that had been claimed impossible to make," Strømme adds. A year spent refining the process gave them Upsalite.

While creating a theoretical material sounds like cause for celebration, Strømme says the major scientific breakthrough is to be found in its amazing properties. No other known carbonate has a surface area as large as 800 sq m per gram. Though scientists have created many new high surface area materials with nanotechnology, such as carbon nanotubes and zeolites, what makes Upsalite special is the minuteness of its nanopores.

Each nanopore is less than 10 nanometers in diameter which results in one gram of the material having a whopping 26 trillion nanopores. "If a material has many small pores," explains Strømme, "it gives the material a very large surface area per gram, which gives the material many reaction sites, i.e. sites that can react with the environment, with specific chemicals, or in the case of Upsalite, with moisture."

Upsalite's moisture absorption properties are striking. It was found to absorb 20 times more moisture than fumed silica, a material used for cat box fillers and as an anti-caking agent for moisture control during the transport of moisture sensitive goods. This means that you'd need 20 times less material to do the moisture control job.

Its unique pore structure also opens up new applications in drug delivery. The pores can host drugs that need protection from the environment before being delivered to the human body. It's also useful in thermal insulation, drying residues from oil and gas industries, and as a dessicant for humidity control. Potential applications are still being discovered as the material undergoes development for industrial use.

CCCEP Spring Lecture: Copenhagen 2009 vs Paris 2015 - Can the media influence the outcome of the UN's climate change talks? | Climate - Water - Ecology - People and Sustainability post Rio+20 | Scoop.it
Copenhagen 2009 vs Paris 2015: Can the media influence the outcome of the UN's climate change talks? Leo Hickman, editor of CarbonBrief.org and former Guardian journalist, will compare media coverage of climate change in 2015 to 2009. Both years feature key UN summits aimed at securing a global climate deal but a lot has happened in between. Has the media's attitude to reporting - and commenting on - climate change moved on, too?

Biographies
Leo Hickman is the Director and Editor of Carbon Brief. He previously worked for 16 years as a journalist, editor and author at the Guardian newspaper. Before joining Carbon Brief, he was WWF-UK's chief advisor on climate change. In 2013, he was awarded an honorary doctorate by the University of Exeter in recognition of his journalism. His books include A Life Stripped Bare, The Final Call and Will Jellyfish Rule the World?
Professor Jouni Paavola (Chair) is Professor of Environmental Social Science and Director of Postgraduate Research Studies in the Faculty of Environment at the University of Leeds. He is also Director of the ESRC Centre for Climate Change Economics and Policy (CCCEP). His research examines environmental governance institutions and their environmental, economic, and social justice implications. He leads the CCCEP second phase research theme on enabling rapid transitions in mitigation and adaptation.

Directions
Leeds University Business School is located to the west of the University of Leeds campus, at the junction of Clarendon Road and Moorland Road, about a 20 minute walk from Leeds city centre.
The Maurice Keyworth Lecture Theatre is situated in the Maurice Keyworth Building, just past the Business School reception.(Building 19 on the campus map  http://www.leeds.ac.uk/site/custom_scripts/campus_map.php).
You will be able to enter the lecture theatre from 5.40pm. Please aim to be in your seats no later than 5.55pm to allow a prompt start at 6.00pm.

Rivers in the Sky? No, it’s not science fiction. - IEAGHG - Carbon Capture and Storage | Climate - Water - Ecology - People and Sustainability post Rio+20 | Scoop.it
Carbon capture and storage (CCS) is one of the technologies that has the potential to mitigate the effects of climate change. In simple terms, CO2 can be captured from power stations or other large emission sources, transported via pipelines or ships and injected very deep underground into suitable geological storage formations where it will remain safe and secure and not contribute to global warming and climate change.
