Congratulations to to Joanna Potrykus, Dagmar Urgast and their co-authors

          their paper about Host-Imposed Copper Poisoning Impacts Fungal Micronutrient Acquisition during Systemic Candida albicans Infections is among the top 10 % most cited Plos one papers published in 2016


November 2019

Angstone took part in the November 2019 Graduation ceremony, also present was Wilka from the Oil and Gas Chemistry taught master course.

Angstone latest paper was accepted in STOTEN. In it he describes the effects different watering regime and zerovalent iron on cadmium uptake and arsenic methylation in Malawi rice cultivars.
