April 24 marks Corrosion Awareness Day – a global reminder of the importance of understanding and preventing corrosion. Although corrosion is not always visible, its impact is all around us: in the bridges we cross, the buildings we live and work in, and even in the preservation of art and cultural heritage.
To mark the occasion, we created a video showcasing real-life corrosion cases from our Photo of the Month series. Beneath the visual intrigue lies a serious challenge: corrosion threatens public safety, drives up maintenance costs, and results in significant resource waste. Globally, it causes financial losses in the billions and contributes to environmental burdens that could be avoided.While corrosion cannot be completely eliminated, science offers powerful tools to manage and mitigate its effects. You can explore our past Corrosion Day videos here: https://www.youtube.com/@K3-JSI

Throughout history, women have played a vital role in electrochemistry and corrosion science, pushing boundaries and driving innovation despite significant challenges. Their pioneering contributions have advanced material science, improved industrial safety, and laid the foundation for modern electrochemical applications. However, their efforts have often been overlooked. Only 30% of science and technology professors worldwide are female, and between 2016 and 2020, women received just 19% of prestigious research prizes. In Slovenia, the representation of women in science reflects similar challenges. As of 2022, women comprised 44% of all doctorate holders in the country. Notably, among individuals under 50, the gender ratio is relatively balanced, but in the 65 and older age group, only 27% of doctorate holders are women. Encouragingly, half of the new doctorate recipients in 2022 were women, indicating progress in gender parity among emerging scientists. However, disparities persist in certain fields such as information and communication technologies. Additionally, female doctorate holders in Slovenia earn, on average, nearly 12% less than their male counterparts, highlighting ongoing gender pay gaps in the scientific community.
At K3, Department of Physical and Organic Chemistry at the Jožef Stefan Institute, we are proud to contribute to the advancement of corrosion science. One of our leading researchers, Dr. Ingrid Milošev, has dedicated her career to understanding corrosion protection and biomaterials, earning international recognition, including the 2024 H. H.
