Core–shell nanowires offer great potential to enhance the efficiency of light-emitting diodes (LEDs) and expand the attainable wavelength range of LEDs over the whole visible spectrum. Additionally, nanowire (NW) LEDs can offer both improved light extraction and emission enhancement if the diameter of the wires is not larger than half the emission wavelength (λ/2). However, AlGaInP nanowire LEDs h
Although they are often subjected to critical scrutiny, formal geopolitical practices have rarely been put on trial. One exception is the case of Gudmund Hatt (1884-1960), professor of human geography at Copenhagen University from 1929 to 1947, who was found guilty of “dishonorable national conduct” for his geopolitics during the German occupation. As a contribution to the critical history of geop
Over the past decades, a ‘neoclassical geopolitics’ has emerged in and beyond the field of International Relations. This diverse practice reproduces many of the problems that characterised classical geopolitics, notably an excessive tendency to explain politics on the basis of ostensibly permanent geographical factors. As a contribution to the interdisciplinary dialogue between International Relat
