Scientific Reports Study offers new theoretical approach to describing non-equilibrium phase transitions
Two physicists at Argonne offered a way to mathematically describe a particular physics phenomenon called a phase transition in a system out of equilibrium. Such phenomena are central in physics, and understanding how they occur has been a long-held and vexing goal; their behavior and related effects are key to unlocking possibilities for new electronics and other next-generation technologies.

Energy & Environmental Science Argonne researchers study how reflectivity of biofuel crops impacts climate
Researchers at Argonne National Laboratory have conducted a detailed study of the albedo (reflectivity) effects of converting land to grow biofuel crops. Based on changes in albedo alone, their findings reveal that greenhouse gas emissions in land use change scenarios represent a net warming effect for ethanol made from miscanthus grass and switchgrass, but a net cooling effect for ethanol made from corn

Scientific Reports Argonne researchers posit way to locally circumvent Second Law of Thermodynamics
For more than a century and a half of physics, the Second Law of Thermodynamics, which states that entropy always increases, has been as close to inviolable as any law we know. In this universe, chaos reigns supreme. But researchers with Argonne announced recently that they may have discovered a little loophole in this famous maxim. Their research, published in Scientific Reports, lays out a possible avenue to a situation where the Second Law is violated on the microscopic level.

Journal of the American Chemical Society Seeing energized light-active molecules proves quick work for Argonne scientists
To understand how molecules undergo light-driven chemical transformations, scientists need to be able to follow the atoms and electrons within the energized molecule as it gains and loses energy. In a recent study, a team of researchers at Argonne, Northwestern University and the Technical University of Denmark used the ultrafast high-intensity pulsed X-rays produced by the Linac Coherent Light Source to take molecular snapshots of these molecules.

Journal of Chemical Physics Argonne theorists solve a long-standing fundamental problem
Trying to understand a system of atoms is like herding gnats -- the individual atoms are never at rest and are constantly moving and interacting. When it comes to trying to model the properties and behavior of these kinds of systems, scientists use two fundamentally different pictures of reality, one of which is called 'statistical' and the other 'dynamical.'
