How Water May Have Destroyed The Martian Atmosphere

  The indications are that at one time mars was both warmer and had an atmosphere thick enough for liquid water to exist. Was this the factor that actually destroyed the atmosphere turning it into the frigid barren waste that it is today. It is a possibility that is well worth considering. The process of…

Nano-engineering enhances charge transport, promises more efficient future solar cells

(Phys.org) -Solar cells based on semiconducting composite plastics and carbon nanotubes is one of the most promising novel technology for producing inexpensive printed solar cells. Physicists at Umeå University have discovered that one can reduce the number of carbon nanotubes in the device by more than 100 times while maintaining exceptional ability to transport charges. This is achieved thanks to clever nano-engineering of the active layer inside the device. Their results are published as front page news in the journal Nanoscale.

Move over, silicon, there’s a new circuit in town

(Phys.org) -When it comes to electronics, silicon will now have to share the spotlight. In a paper recently published in Nature Communications, researchers from the USC Viterbi School of Engineering describe how they have overcome a major issue in carbon nanotube technology by developing a flexible, energy-efficient hybrid circuit combining carbon nanotube thin film transistors with other thin film transistors. This hybrid could take the place of silicon as the traditional transistor material used in electronic chips, since carbon nanotubes are more transparent, flexible, and can be processed at a lower cost.
