Why sustainability practitioners need to embrace big data (rather than be scared of it)
The outcome of the 2012 presidential election in the US, which saw President Barack Obama fight to win a second term against the Republican Mitt Romney, was uncertain. Obama’s record-breaking fundraising was no guarantee of success in the face of challenging domestic issues such as how the US would respond to the economic downturn or the future of the Affordable Care Act. But one man did ...

Production control of solder powder - Case Study
In the past most industrial solder pastes were made using oxidised powder produced by simple air atomisation. Pressure to improve the control of the size range of solder pastes, and to avoid the use of corrosive halide fluxes, has led to a demand for lower oxide levels. In addition increased use of automated oxygen analyzer application systems has led to much more critical specifications for ...
