Sammanfattning : Heterogeneous catalysis is an important cornerstone of modern society with strong ties to the development of sustainable sources of energy and products. Catalysts are typically realized as supported metal nanoparticles that offer active sites that can accelerate chemical reactions by providing energetically more favorable reaction paths. LÄS MER
Sammanfattning : Currently metal nanoparticles (NPs) are a subject of interest regarding many applications, in particular chemical gas sensing, as the associated environmental issues are of substantial importance. Metal NPs are attractive due to their fascinating optical properties and primarily, localized surface plasmon resonance (LSPR) which strongly depends on size and shape of NPs. LÄS MER
Sammanfattning : Our continuously increasing concerns about our health, safety, environment and climate has brought about a need for more sophisticated sensors that enable reliable detection of a variety of events. Sensors are today omnipresent in daily life. LÄS MER
Sammanfattning : Nanoparticles are, due to their large exposed surface area, widely used in the field of heterogeneous catalysis where they accelerate and steer chemical reactions. Although catalysis has been known about for centuries, the scrutiny of catalysts under realistic application conditions is still a major challenge. LÄS MER
Sammanfattning : Alloys have for a long time been important in the development of our society; from the bronze age, where man learned how to alloy copper with tin, to today, where many products are made of steel and aluminum alloys. Similarly, but maybe not as generally well known, also in heterogeneous catalysis alloys are explored to develop solutions to increase activity and selectivity of chemical processes. LÄS MER
