Abstract: Science and emerging technologies should not be predominantly tasked with furnishing us with more sustainable societies. Continuous short-term technological bail outs without taking into account the longer socio-cultural incubation times required to transition to ‘weakly sustainable’ economies squander valuable resources and time. Emerging technologies need to be deployed strategically to buy time in order to have extended political, social and ethical discussions about the root-causes of unsustainable economies and minimize social disruptions on the path towards global sustainability. Keywords: Nanoscience; (...) nanotechnology; expanded materials design space; dematerialization; sustainability; permanent resource crises . (shrink)

Microscopy allows us to observe objects we cannot see with our eyes alone. With a light microscope, we can distinguish objects at the scale of the wavelengths of visible light just under a micrometer. Around 1870 Ernst Abbe, who laid the foundation of modern optics, suggested that the resolution of a microscope would improve by using some yet-unknown radiation with shorter wavelengths than visible light, that is, below 390 nanometers (1 nm = 10−9 m). Electrons can have wavelengths near 1 (...) picometer (1 pm = 10−12 m) and should therefore allow atoms to be distinguished since they are typically at least a few hundred pm apart. In this oversimplified view, further decreasing the wavelength of the radiation should allow us to increase the resolution of electron microscopy even more. However, this can only be done by increasing the energy of the radiation, which would ultimately destroy the samples. Other factors also affect the resolution of electron microscopes, among them non-ideal imaging properties of electromagnetic lenses, which result in false images. It took more than half a century to understand and control these aberrations and separate objects less than 1 Ångstrom (1 Å = 10−10 m) apart. (shrink)

After introducing the concept of compressed sensing as a complementary measurement mode to the classical Shannon-Nyquist approach, I discuss some of the drivers, potential challenges and obstacles to its implementation. I end with a speculative attempt to embed compressed sensing as an enabling methodology within the emergence of data-driven discovery. As a consequence I predict the growth of non-nomological sciences where heuristic correlations will find applications but often bypass conventional pure basic and use-inspired basic research stages due to the lack (...) of verifiable hypotheses.

The role of speed in innovations needs to be explored more thoroughly. I advocate here that for innovations which rely on scarce materials, research into more abundant substitutes needs to be accelerated while a regulatory-driven extension of the product life should slow down the number of incremental innovations and reduce our overall footprint on scarce resources. Chemical elements need to be established as global commons whose overuse can be regulated if required. Part of the efficiency gains of innovations could be (...) used for research to offset the ‘rebound effect’ and provide the public with a return on early infrastructure investments. (shrink)
