NREL reports examine economic trade-offs of owning versus leasing a solar photovoltaic system
Two new reports from the Energy Department's National Renewable Energy Laboratory (NREL) examine the economic options customers face when deciding how to finance commercial or residential solar energy systems. NREL analysts found that businesses that use low-cost financing to purchase a photovoltaic (PV) system and homeowners who use solar-specific loans can save up to 30 percent compared with consumers who lease a PV system through a conventional third-party owner.

How ionic: Scaffolding is in charge of calcium carbonate crystals
Nature packs away carbon in chalk, shells and rocks made by marine organisms that crystallize calcium carbonate. Now, research suggests that the soft, organic scaffolds in which such crystals form guide crystallization by soaking up the calcium like an 'ion sponge,' according to new work in Nature Materials. Understanding the process better may help researchers develop advanced materials for energy and environmental uses, such as for removing carbon dioxide from the atmosphere.

Story tips from the Department of Energy's Oak Ridge National Laboratory, January 2015
While researchers in Oak Ridge National Laboratory's buildings group focus on increasing energy efficiency using new foam insulation panels, the nanophase materials sector experiments with catalyst performance, revealing an oxidation discovery that could help reduce vehicle emissions. Additionally, Oak Ridge National Laboratory researchers aim to reduce the size, weight and power for some particle accelerators with development of a new voltage supply. And by using water and nano-sized particles isolated from trees and plants, scientists explore low-cost and nontoxic metal oxides.

Solar cell polymers with multiplied electrical output
A team from Brookhaven Lab and Columbia University has paired up photovoltaic polymers that produce two units of electricity per unit of light instead of the usual one on a single molecular polymer chain. Having the two charges on the same molecule means the light-absorbing, energy-producing materials work efficiently when dissolved in liquids, which opens the way for a wide range of industrial scale manufacturing processes, including 'printing' solar-energy-producing material like ink.

From the bottom up: Manipulating nanoribbons at the molecular level
Researchers at Lawrence Berkeley National Laboratory and the University of California, Berkeley, have developed a new precision approach for synthesizing graphene nanoribbons from pre-designed molecular building blocks. Using this process the researchers have built nanoribbons that have enhanced properties -- such as position-dependent, tunable bandgaps -- that are potentially very useful for next-generation electronic circuitry.

Compact batteries enhanced by spontaneous silver matrix formations
The formation of a highly conductive silver matrix inside an otherwise poorly performing battery enhances its efficiency and offers new potential applications. Scientists used x-rays to see where, when, and how these nanoscale 'bridges' emerge and develop new material designs and optimization techniques.
