An Australian research team has solved one of the worlds big industrial waste headaches - what to do with spent pot lining (SPL) from aluminium smelters.
In a major advance for sustainable mineral production, the "Alcoa Portland SPL Process" developed jointly by Portland Aluminium, Alcoa, Ausmelt and CSIRO renders the hazardous waste harmless and at the same time produces two commercial by-products.
Aluminium smelters worldwide produce about half a million tones a year of the toxic byproduct which, in many cases, simply has to be stored on site because local regulations prevent its disposal in landfill.
Now the Australian breakthrough has turned what was an intractable problem into economically useful products.

Planet Earth experienced a global climate shift in the late 1980s on an unprecedented scale, fuelled by anthropogenic warming and a volcanic eruption, according to new research published this week.
Scientists say that a major step change, or ‘regime shift’, in the Earth’s biophysical systems, from the upper atmosphere to the depths of the ocean and from...

Nerve cells cover their high energy demand with glucose and lactate. Scientists of the University of Zurich now provide new support for this. They show for the first time in the intact mouse brain evidence for an exchange of lactate between different brain cells. With this study they were able to confirm a 20-year old hypothesis.
In comparison to other organs, the human brain has the highest energy requirements. The supply of energy for nerve cells and the particular role of lactic acid...
In laser material processing, the simulation of processes has made great strides over the past few years. Today, the software can predict relatively well what will happen on the workpiece. Unfortunately, it is also highly complex and requires a lot of computing time. Thanks to clever simplification, experts from Fraunhofer ILT are now able to offer the first-ever simulation software that calculates processes in real time and also runs on tablet computers and smartphones. The fast software enables users to do without expensive experiments and to find optimum process parameters even more effectively.
Before now, the reliable simulation of laser processes was a job for experts. Armed with sophisticated software packages and after many hours on computer...
