Synthesis of novel MoWO4 with ZnO nanoflowers on multi-walled carbon nanotubes for counter electrode application in dye-sensitized solar cells source:natureAbstractNovel MoWO4 with ZnO nanoflowers was synthesized on multi-walled carbon nanotubes (MW-Z@MWCNTs) through a simple hydrothermal method, and this unique structure was applied as a counter electrode (CE) for dye-sensitized solar cells (DSSC) for the first time. The synergetic effect of ZnO nanoflowers and MoWO4 on MWCNTs was systematically investigated by different techniques. The amount of MWCNTs was optimized to achieve the best ...

source:sci-newsTo build the global map of hydrogen abundances on the Moon, Johns Hopkins Applied Physics Laboratory researcher David Lawrence and his colleagues used data from the Neutron Spectrometer, one of five instruments mounted on NASA’s Lunar Prospector spacecraft.Lunar Prospector, which was deployed by NASA in 1998, orbited the Moon for 1.5 years and sent back the first direct evidence of enhanced hydrogen at the lunar poles, before impacting the lunar surface.The researchers calibrated the data to quantify the amount of hydrogen by the corresponding decrease of neutrons measured by th...

source:resource-recyclingA technology that will allow recyclers to extract valuable metals from e-scrap like shredded hard drives without affecting the other materials is entering its pilot plant stage.Daniel Bina, CEO of Critical Materials Recycling and TdVib, said the new method will make rare earth recycling more accessible at a time when there is a critical need for more domestic supply.The method, called acid-free dissolution reaction (ADR), is unique because it can selectively target rare earths and doesn’t use acids to do so, according to Bina. It was developed at the Critical Materials...
