Particulate matter-attributable mortality and relationships with carbon dioxide in 250 urban areas worldwide
(Journal article; Peer reviewed, 2019)Urban air pollution is high on global health and sustainability agendas, but information is limited on associated city-level disease burdens. We estimated fine particulate matter (PM2.5) mortality in the 250 most populous ... -
Path Exchange Method for Hybrid Life-Cycle Assessment
(Master thesis, 2009)To keep process-specificity while extending system boundaries hybrid techniques were developed allowing the micro structure of the important parts of a system to be revealed at the same time the entire economic system in ... -
Path-Following Method to Determine the Field of Values of a Matrix with High Accuracy
(Journal article; Peer reviewed, 2018)We describe a novel and efficient algorithm for calculating the field of values boundary, $\partial\textrm{W}(\cdot)$, of an arbitrary complex square matrix: the boundary is described by a system of ordinary differential ... -
Path-Following Methods for Calculating Linear Surface Wave Dispersion Relations on Vertical Shear Flows
(Journal article; Peer reviewed, 2020)The path-following scheme in Loisel and Maxwell (SIAM J Matrix Anal Appl 39(4):1726–1749, 2018) is adapted to efficiently calculate the dispersion relation curve for linear surface waves on an arbitrary vertical shear ... -
Pathways to low-cost clean hydrogen production with gas switching reforming
(Peer reviewed; Journal article, 2020)Gas switching reforming (GSR) is a promising technology for natural gas reforming with inherent CO2 capture. Like conventional steam methane reforming (SMR), GSR can be integrated with water-gas shift and pressure swing ... -
Pathways toward a carbon-neutral Swiss residential building stock
(Journal article, 2020)Current policies to reduce energy consumption and CO2 emissions associated with buildings focus on technological developments such as energy efficiency, renovation rates and renewable energies. While technological developments ... -

Paving the way for sustainable decarbonization of the European cement industry
(Peer reviewed; Journal article, 2024)Cement production is a main source of carbon emissions. Decarbonization options exist, but their climate change mitigation potential, feasibility and environmental implications are still unclear. Here we assess 15 ... -
Pd/CeO2 catalysts as powder in a fixed-bed reactor and as coating in a stacked foil microreactor for the methanol synthesis.
(Journal article; Peer reviewed, 2016)Pd/CeO2 as a catalyst for methanol synthesis has been studied in a microreactor consisting of 14 structured foils in a fixed-bed laboratory reactor. Methanol synthesis was carried out at 80 bar and 300 °C with a syngas ... -
Peltier effects in lithium-ion battery modeling
(Peer reviewed; Journal article, 2021)A high battery temperature has been shown to be critical for lithium-ion batteries in terms of performance, degradation, and safety. Therefore, a precise knowledge of heat sources and sinks in the battery is essential. We ... -
Pelton Turbine - Model Test of a Runner
(Master thesis, 2015)Even though the Pelton turbine is more than a 100-year-old invention, there is still a lack of knowledge regarding the flow inside the bucket. A deeper understanding of the influence of bucket design on the flow behavior ... -
