Targets of Biggest Global Carbon Emitters Flunk Fairness Test

Carbon nanotube ield emitters

Application of various one-dimensional nanostructure materials as field emission sources has attracted extensive scientific efforts. Elongated structures are suitable for achieving high field-emission-current density at a low electric field because of their high aspect ratio. Area of its application includes a wide range of field-emission-based devices such as flat-panel displays, electron micr...

the relationship between eq, iq and test format: a study on test fairness

the major aim of this study was to investigate the relationship between iq, eq and test format in the light of test fairness considerations. this study took this relationship into account to see if people with different eq and iq performed differently on different test formats. to this end, 90 advanced learners of english form college of ferdowsi university of mashhad were chosen. they were ask...

Achieving high-current carbon nanotube emitters.

When a carbon nanotube emitter is operated at high currents (typically above 1 microA per emitter), a small voltage drop ( approximately few volts) along its length or at its contact generates a reverse/canceling electric field that causes a saturation-like deviation from the classical Fowler-Nordheim behavior with respect to the applied electric field. We present a correction to the Fowler-Nor...

Climate change is not the biggest global health threat.

The UCL Lancet Commission on climate change and health (May 16, p 1693) concludes: “Climate change is the biggest global health threat of the 21st century”. In this report, the authors emphasise not only the immediacy and gravity of this threat, but also the directness: while the poorest in the world will be the fi rst aff ected, none will be spared. The escalating carbon footprint of the devel...
