(Elsevier BV, 2016-07)Alkaline phosphatase is a homodimeric metallo-hydrolase where both Zn2+ and Mg2+ are important for catalysis and stability. Cold-adapted alkaline phosphatase variants have high activity at low temperatures and lower thermal stability compared with ... -
(Springer Science and Business Media LLC, 2018-09-14)Recycling Phosphorus (P) from urban wastewater can secure part of domestic agricultural P supply and contribute to a circular P supply chain. In this paper, we use literature review, stakeholder interviews and analysis, and systems dynamics for the ...

(Elsevier BV, 2020-09)Phosphorus (P) availability is essential for global food security. A system dynamics model running from 1961 to 2050 was built for this study, linking global P supply to social, economic and environmental dynamics at regional level. Simulation results ...

(University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2021-02)Phosphorus is an essential yet irreplaceable macronutrient for agriculture and thus plays a key role in global food security. Most of the phosphate fertilizers are produced from phosphate rock, a finite mineral resource that is mined and processed at ...

(The Electrochemical Society, 2017)Many factors may contribute to loss of current efficiency (CE) in aluminum reduction and one of them is a presence of impurities. In this work, the effect of phosphorus on CE is studied in a laboratory cell at different current densities. Due to a ...

(Springer Science and Business Media LLC, 2019-09-04)Phosphorus (P) is an essential macronutrient in agriculture; however, lack of reporting makes its supply chain a black box. By using literature synthesis on the P challenge, we identify four areas where the reporting process is problematic: P reserves ...
