  1. 1. Top-down Methodology to Identify Opportunities for Industrial Symbiosis Partnerships

    Författare :Joao Patricio; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circular Economy; Top-down methods; Industrial Waste; Recycling; Material Inputs; Industrial Symbiosis;

    Sammanfattning : Industries in Europe are responsible for generating approximately 190 Mtons of waste; a figure which is expected to rise, as a significant increase in the consumption of raw materials is predicted to occur in the near future. This may lead to escalating environmental problems, including resource depletion, soil degradation, and climate change. LÄS MER

  2. 2. Top-down Fabrication Technologies for High Quality III-V Nanostructures

    Författare :Shagufta Naureen; Srinivasan Anand; Clivia M. Sotomayor Torres; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; III-V nanostructures; colloidal lithography; top-down fabrication; dry etching; quantum well; multilayer structures; nanowires; nanopillars; nanodisks; mono-layer etching; surface passivation; photoluminescence; carrier life time; total reflectivity; photonic crystals; nanomesh;

    Sammanfattning : III-V nanostructures have attracted substantial research effort due to their interesting physical properties and their applications in new generation of ultrafast and high efficiency nanoscale electronic and photonic components. The advances in nanofabrication methods including growth/synthesis have opened up new possibilities of realizing one dimensional (1D) nanostructures as building blocks of future nanoscale devices.
