‘Greener’ way to assemble materials for solar applicationsOctober 8, 2015

Polymers used in solar cells today require solvents that can harm the environment, but scientists using the Advanced Photon Source at Argonne have found a “greener” way to control the assembly of photovoltaic polymers in water using a surfactant— a detergent-like molecule—as a template.

A Generalized Queuing Model and Its Solution Properties

Queuing phenomena and dynamics are common and fundamental in transportation and other service systems. To date, a number of queuing models have been proposed, but the analytical insights on their global properties are still limited. This is primarily due to the existence of discontinuities associated with queuing processes, which are difficult to tackle with conventional differential or difference equation methods. Simulations are usually the only tool to employ, but they introduce various artifacts if not properly applied.

SunShot Initiative award funds scaleup of Argonne’s leading-edge thermal energy storage systemSeptember 16, 2015

On September 16, 2015, the U.S. Department of Energy SunShot Initiative program announced funding awards to several research projects that aim to make concentrating solar power (CSP) plants cost competitive with traditional forms of electricity.
