Hey hive mind - I'm keen to start a PhD and move toward academia, and am thinking about potential research topics. I'm an experienced structural #engineer and want to transition toward #sustainability as much as I can. But I'm not sure what that means for viable #research areas...

I have particular expertise in mechanics of #materials, software development ( #Python and #JavaScript), and cold-formed steel / #buckling of thin-walled structures.

Anyone out there have any suggestions for specific topics or general directions?

Green electronics thanks to biodegradable circuit boards

They are the "heart" of every electronic device, from laptops to electric toothbrushes: printed circuit boards, also known as PCBs. These rigid boards are covered with copper traces and soldered electronic components and are usually of a telltale green color. They are, however, not exactly environmentally friendly.

“It would be disingenuous to attempt to disentangle the human rights abuses connected to creating technologies from their environmental impacts.”

Students develop novel multi-metal 3D printing process

Students at ETH Zurich have developed a laser powder bed fusion machine that follows a circular tool path to print round components, which allows the processing of multiple metals at once. The system significantly reduces manufacturing time and opens up new possibilities for aerospace and industry. ETH has filed a patent application for the machine, and the results are published in the CIRP Annals.
