A University of Southern California team has produced flexible transparent carbon atom films that the researchers say have great potential for a new breed of solar cells.
Organic photovoltaic (OPV) cells have been proposed as a means to achieve low cost energy due to their ease of manufacture, light weight, and compatibility with flexible substrates," wrote Chongwu Zhou, a professor of electrical engineering in the USC Viterbi School of Engineering, in a paper recently published in the journal ACS Nano.

natural gas production has grown nearly 14%, which is in sharp contrast to the flat performance of production in the decade before that.
While gas production has enjoyed a significant uptick over the last few years, the same cannot be said for consumption.
