Promising new prototype of battery

An alternative technology to Li-ion has been designed for application in specific sectors. The researchers have developed the first battery using sodium ions in the usual “18650” format, an industry standard. The main advantage of the prototype is that it relies on sodium, an element far more abundant and less costly than lithium. The batteries have displayed performance levels comparable to their lithium counterparts, and this new technology is already attracting industrial interest. It could be used to store renewable energies in the future, say researchers.

After Paris, it’s time for Canada to finally join IRENA

IRENA is the International Renewable Energy Agency, a UN-affiliated organization established in 2009 to promote awareness and growth of renewable energy technologies on the global stage. It’s a kind of counter-balance to existing agencies that have long represented the fossil fuel and nuclear industries. The idea for IRENA goes as far back as 1981, but it took a quarter century to get the political traction it needed. Today, 145 countries have officially joined IRENA and another 30 are in the process of becoming members. That would bring the total to 175. By comparison, the 42-year-old International Energy Agency has only 29 members, while the 59-year-old International Atomic Energy Agency has 167 members. Canada is a founding member of the IEA and IAEA, yet Canada is the only G8 countries …

3D ‘nanobridges’ formed using electron beam writing with tiny jets of liquid precursor

Researchers have demonstrated a new process for rapidly fabricating complex three-dimensional nanostructures from a variety of materials, including metals. The new technique uses nanoelectrospray to provide a continuous supply of liquid precursor, which can include metal ions that are converted to high-purity metal by a focused electron beam.
