Where Microscopes Meet Industry
When scientists first peered beyond the visible surface of materials, they unlocked a hidden universe where atomic interactions determine everything from smartphone durability to vaccine efficacy.
For 20 transformative years, the ECASIA conference series has served as Europe's premier crossroads for this invisible frontier, bridging fundamental discoveries with industrial breakthroughs. Born from a simple realization—that applied surface scientists needed their own forum—this biennial gathering has evolved into a catalytic force shaping how we understand and engineer the interfaces that define our material world 1 .
Surface science techniques reveal the hidden atomic world that determines material properties.
The ECASIA Phenomenon: From Niche Gathering to Scientific Powerhouse
Founding Vision
The ECASIA story began in late 1982 when the Dutch SCADEG group and UKESCA Users Group identified a critical gap: Europe lacked a dedicated forum for scientists applying surface analysis techniques to real-world problems. By 1985, their vision materialized as the first official conference, establishing a biennial rhythm that continues today. The founding principle was revolutionary for its time: scientific rigor and industrial relevance weren't mutually exclusive but fundamentally interconnected 1 .

Decoding Surfaces: The Experiment That Changed Corrosion Science
The Perplexing Problem
In the late 1990s, aerospace engineers faced mysterious microbial corrosion in fuel tanks. Traditional inhibitors failed unpredictably until an ECASIA-presented study unveiled why: surface heterogeneity required molecular-scale customization of protective films. This became a landmark demonstration of surface science's industrial impact 1 .
Methodology: Molecular Armor Engineering
The pioneering experiment combined multiple techniques in a novel workflow:
- Surface Preparation: Aircraft-grade aluminum alloy coupons were polished to Ra < 0.02 μm and contaminated with controlled hydrocarbon films.
- SAM Formation: Self-assembled monolayers (SAMs) of three candidate inhibitors (thiol-based) were applied:
- Inhibitor A: Octadecanethiol
- Inhibitor B: 16-Mercaptohexadecanoic acid
- Inhibitor C: Custom fluorinated thiol
- Accelerated Corrosion Testing: Samples underwent 500-hour salt spray (ASTM B117) and electrochemical impedance spectroscopy (EIS).
- Post-Test Analysis:
- XPS Depth Profiling: Measured elemental composition changes within corrosion pits
- AFM Nanomechanical Mapping: Quantified adhesion forces at interface defects
- ToF-SIMS Imaging: Revealed spatial distribution of inhibitor molecules
Molecular-scale surface engineering revolutionized corrosion protection in aerospace applications.
Corrosion Protection Performance Metrics
| Inhibitor | Film Thickness (nm) | Corrosion Rate (mpy) | Failure Mechanism |
|---|---|---|---|
| Unprotected | N/A | 38.7 ± 2.1 | Pitting corrosion |
| Inhibitor A | 2.1 ± 0.3 | 12.4 ± 1.3 | Film delamination |
| Inhibitor B | 1.8 ± 0.2 | 5.2 ± 0.8 | Localized detachment |
| Inhibitor C | 2.4 ± 0.4 | 1.1 ± 0.3 | Minimal degradation |
Revelatory Results
The data overturned conventional wisdom about corrosion protection mechanisms:
Analysis revealed Inhibitor C's superiority stemmed from:
- Fluorine-enriched domains creating hydrophobic barriers (XPS showed 19 at% F)
- Defect self-healing: Mobile side chains migrating to damaged areas (ToF-SIMS tracking)
- Energy dissipation: Nanomechanical absorption of shear stresses (AFM force curves)
The study demonstrated that molecular conformation mattered more than thickness—a paradigm shift influencing inhibitor design for decades 1 .
