The Donnan electric potential arises from an imbalance of charges at the interface of a charged membrane and a liquid, and for more than a century it has stubbornly eluded direct measurement. Many researchers have even written off such a measurement as impossible. But that era, at last, has ended. With a tool that’s conventionally used to probe the chemical composition of materials, scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) recently led the first direct measurement of the Donnan potential.

When the nuclei of atoms are about to collide in an experiment, their centers never perfectly align along the direction of relative motion, leading to complex collisions. A deblurring algorithm from optics can help nuclear physicists examine the pattern of emissions from these collisions as if the initial nuclear centers were under tight control.

Lignin in plant cell walls can be broken down into component polymers that can in turn be converted into valuable bioproducts, but deconstructing lignin is difficult. Researchers have now showed that some solvents are more effective than others at getting between the cellulosic and lignin polymers in switchgrass variants.

A new computational analysis by theorists at Brookhaven National Laboratory and Wayne State University supports the idea that photons (a.k.a. particles of light) colliding with heavy ions can create a fluid of "strongly interacting" particles. In a new paper they show that calculations describing such a system match up with data collected by the ATLAS detector at Europe's Large Hadron Collider (LHC).
