M-ERA.NET published a Success story on the project COR-ID, acronym for Design of corrosion resistant coatings targeted for versatile applications. Project is coordinated by dr. Ingrid Milošev of the Department of Physical and Organic Chemistry and comprises partners from Slovenia (Talum d.d. Kidričevo), France (ENSCP, CNRS) and Hungary (Eötvös Loránd University). The objective of the project is to design multifunctional coatings which would simultaneously act as high-quality corrosion inhibitors and offer additional properties like hydrophobicity. These coatings will be used also for less corrosion resistant Al alloys or secondary Al alloys by industrial partner Talum. A “virtual laboratory” is being established to enable the construction of parameters used in larger-scale simulations, such as, semi-empirical based molecular-dynamics. Pilot device for large-scale testing is under construction. The project goals are being realized through the ICME (Integrated Computational Materials Engineering) paradigm consisting of integration of three fundamental disciplines: multi-scale modeling, multi-scale chemical synthesis, and high-throughput electrochemical and corrosion experimental testing and verification.
Journal of The Electrochemical Society published the review on conversion coatings based on zirconium and/or titanium written by I. Milošev and G.S. Frankel (Fontana Corrosion Center, The Ohio State University, USA). Conversion coatings based on Zr or Ti seem to a good choice as an alternative technology to legacy chromate and phosphate conversion coatings associated with the health and environmental issues. This literature review summarizes the scientific results in this rapidly growing area of research. Following the description of composition of conversion bath and deposition mechanism, the effects of process parameters for conversion baths are presented together with coating characteristics such as composition, morphology and thickness. The effects of the type of substrate and substrate pre-treatment are explored for the most-studied substrates. The corrosion performance of the conversion coatings is discussed, as well as adhesion of organic coatings. Advantages and potential drawbacks are also presented.
A two day annual meeting of the M-era.Net project "COIN DESC: Corrosion inhibition and dealloying descriptors" took place on 16–17 November, 2017, at Universitat Politècnica de Catalunya in Barcelona. The principle objective of the project is to design corrosion resistant copper-based alloy systems by using corrosion inhibitors and to deepen the mechanistic understanding of corrosion inhibition. The purpose of the meeting was twofold: (i) to present, review, and discuss the results obtained during the first project year, and (ii) to plan the project activities for the following year.
Annual meeting of the project COR_ID within M-ERA.NET (European Research Area, an EU funded network) took place on November 9 and 10, 2017 at the Eötvös Loránd University in Budapest. The main aim of the project Design of corrosion resistant coatings targeted for versatile applications (acronym COR_ID) is to design and engineer new coatings for aluminum alloys with targeted properties of increased corrosion resistance, specific hydrophobic properties, prolonged service life-time and reduced ecological impact. The project work-plan proceeds according to the integrated computational materials engineering (ICME) principles. The meeting was devoted to the presentation of the results and plan of future activities. Partners: Jožef Stefan Institute (Slovenia), Talum d.d. Kidričevo (Slovenia), Chimie ParisTech, CNRS (France) and Eötvös Loránd University (Hungary).
The CORROSION journal has published a special issue devoted to biocorrosion of metals in human body edited by Ingrid Milošev, Ph.D. Understanding the mechanism of biocorrosion and metal degradation in human body—identification of the metal corrosion and wear products, and their effects on human body is of paramount importance for the safety and long-term well-being of patients with metal implants. Special issue features twelve articles divided into in vitro studies, retrieval and model clinical studies. Two articles are review papers written by Jeremy Gilbert from Clemson University and Ingrid Milošev. The special issue is aimed for readers not yet familiar with the biocorrosion topic, as well as for researchers already devoted to this topic.

His contribution to the development of software tools for molecular modeling is remarkable, the developed software is open source and freely accessible. Dr. Kokalj is the most frequently cited author in Slovenia in the field of chemistry, and he is also ranked at the top in other indicators of excellence.
The show "Ugriznimo znanost" (Let's take a bite of science) entitled "Boj proti rji" (The fight against rust) which aired on RTV Slovenija 1 on 19. 10. 2017, was dedicated to corrosion and methods used for corrosion prevention of metallic materials. "The industry is thought to have more than a trilion euro of yearly losses due to corrosion, moreover the cost often includes the loss of human life. How and why does it occur? How do we protect against it? How can we identify corrosion in tough to reach places, such as concrete pillars, constructions and other systems? New coatings are being developed at the Jožef Stefan Institute, with the aim of replacing the all around present but dangerous chromate based coatings. Will they be able to defeat corrosion?" Coworkers of the Department of Physical and Organic Chemistry appeared in the show. In the studio dr. Peter Rodič concisely explained and demonstrated how and why corrosion occurs. We demonstrated how modern corrosion prevention coatings, such as sol-gel, conversion, superhydrophobic and self-healing coating are developed at our department. Besides dr. Rodič, young researcher Urša Tiringer (MSc in Chemistry) and Barbara Kapun (BSc in Chemical Technology) also appeared in the show. Researchers from the Slovenian National Building and Civil Engineering Institute also appeared alongside our coworkers. Protection against corrosion is an extremely relevant field in all areas of life - from the protection of ordinary metallic fences and bridges to ships, cars, airplanes and it is even relevant in mobile phones and microelectronics.

Springer has published the 60th volume of the series Modern Aspects of Electrochemistry edited by Stojan S. Djokić. This eminent and most known series of books in electrochemistry provides an overview of broad issues in electrochemistry and has been published since early 1950's. The 60th volume is entitled "Biomedical and Pharmaceutical Applications of Electrochemistry". Ingrid Milošev authored the chapter "Surface Treatments of Titanium with Antibacterial Agents for Implant Applications" . Bacterial infection of an implant is a serious complication after implantation. Contemporary results of various surface treatments aimed to prevent or reduce the incidence infection are reviewed and critically discussed. There are two general approaches: passive and active coatings. Passive coatings comprise antiadhesion and bacteria repellent coatings obtained via surface nanostructuring, substrate composition or surface chemistry. Active coatings are based on intrinsically antimicrobial materials like chitosan, hyaluronic acid and inorganic agents like silver and zinc oxide. General characteristics of these agents are reviewed, as well as their efficiency against different bacteria when added to titanium oxide or hydoxyapatite coatings.
- The largest green chemistry conference in 2016 - The 6th International IUPAC Conference on Green Chemistry (ICGC-6), consisting of 326 participants, took place in September 4-8 2016 in Venice, Italy.
