Polarization features of optically pumped CdS nanowire lasers
, 2014 High quality CdS nanowires suspended in air were optically pumped both below and above the lasing threshold. The polarization of the pump laser was varied while emission out of the end facet of the nanowire was monitored in a 'head-on' measurement ...

Global satellite survey reveals uncertainty in landfill methane emissions
NatureAbstract Methane is a potent but short-lived greenhouse gas and rapid reductions of its anthropogenic emissions could help decrease near-term warming 1 . Solid waste emits methane through the decay of organic material, which amounts to about 10% of total anthropogenic ...
