Making money from lignin: Roadmap shows how to improve lignocellulosic biofuel biorefining
When making cellulosic ethanol from plants, one problem is what to do with a woody agricultural waste product called lignin. The old adage in the pulp industry has been that one can make anything from lignin ...
Tiny camera records details of scene without losing sight of the big picture
To capture all the details of a crime scene, you might take many photos at close range. To get the whole scene at once, you could use a wide-angle or fisheye lens; but without an especially large lens you ...
