Read moreScientists have discovered how algae that survive in very low levels of light are able to switch on and off a weird quantum phenomenon that occurs during photosynthesis. The function in the algae of this quantum effect, known as coherence, remains a mystery, but it is thought it could help them harvest energy from the sun much more efficiently. Working out its role in a living organism could lead to technological advances, such as better organic solar cells and quantum-based electronic devices.

Read moreBy combining the advantages of two well-established spectroscopy technologies - 2D-electronic and 2D-infrared - two-dimensional electronic-vibrational spectroscopy (2D-EV) is the first that can be used to simultaneously monitor electronic and molecular dynamics on a femtosecond time-scale. The results show how the coupling of electronic states and nuclear vibrations affect the outcome of photochemical reactions.

Read moreResearchers at the Energy Department's National Renewable Energy Laboratory (NREL) are turning to extremely tiny tubes and rods to boost power and durability in lithium-ion batteries, the energy sources for cell phones, laptops, and electric vehicles. If successful, the batteries will last longer and perform better, leading to a cost advantage for electric vehicles.

Read moreNanopores could provide a new way to sequence DNA quickly, but the physics involved isn't well understood. That's partly because of the complexities involved in studying the random, squiggly form DNA takes in solution. Researchers have simplified matters by using a stiff, rod-like virus instead of DNA to experiment with nanopores. Their research has uncovered previously unknown dynamics in polymer-nanopore interactions.
