Cyclodextrin inhibits zinc corrosion by destabilizing point defect formation in the oxide layer
Altin, Abdulrahman; Krzywiecki, Maciej; Sarfraz, Adnan; Toparli, Cigdem; Laska, Claudius; Kerger, Philipp; Zeradjanin, Aleksandar; Mayrhofer, Karl J.J.; Rohwerder, Michael; Erbe, Andreas (Journal article; Peer reviewed, 2018)Corrosion inhibitors are added in low concentrations to corrosive solutions for reducing the corrosion rate of a metallic material. Their mechanism of action is typically the blocking of free metal surface by adsorption, ... -
Cyclodextrins as carriers for organic corrosion inhibitors in organic coatings
Altin, Abdulrahman; Rohwerder, Michael; Erbe, Andreas (Journal article; Peer reviewed, 2017) -
In situ and operando observation of surface oxides during oxygen evolution reaction on copper
Toparli, Cigdem; Sarfraz, Adnan; Wieck, Andreas D.; Rohwerder, Michael; Erbe, Andreas (Journal article; Peer reviewed, 2017)Formation and dissolution of oxide on copper under transpassive conditions, i.e. during OER and transpassive dissolution, in alkaline electrolyte was investigated by a combination of electrochemical techniques and in situ ... -
Pretreatment with a β-cyclodextrin - corrosion inhibitor complex stops an initiated corrosion process on zinc
Altin, Abdulrahman; Vimalanandan, Ashokandand; Sarfraz, Adnan; Rohwerder, Michael; Erbe, Andreas (Journal article; Peer reviewed, 2018)Metal pretreatment is typically the first step in a reliable corrosion protection system. This work explores the incorporation of complexes between the cyclic oligosaccharide β-cyclodextrin (β-CD) and the molecular organic ... -
What is the trigger for the hydrogen evolution reaction? – towards electrocatalysis beyond the Sabatier principle
Zeradjanin, Aleksandar; Polymeros, George; Toparli, Cigdem; Ledendecker, Marc; Hodnik, Nejc; Erbe, Andreas; Rohwerder, Michael; La Mantia, Fabio (Peer reviewed; Journal article, 2020)The mechanism of the hydrogen evolution reaction, although intensively studied for more than a century, remains a fundamental scientific challenge. Many important questions are still open, making it elusive to establish ...
