Focused session on composite and hybrid coatings
Description: The role of the coatings is not only the traditional one (protection and aesthetics), but in addition new advanced functions are required, like special mechanical, chemical, electrical, and optical functions. A wide range of coating technologies offer the possibility to produce advanced and selected surface properties, such as hydrophobic/ hydrophilic coatings, anti-static, non-stick and easy-to-clean coatings, anti-freeze or anti-fogging coatings, scratch-resistant coatings, anti-microbial coatings, catalytic, anti-bacterial, optical, etc. In particular, composites and hybrid coatings are very promising options to develop new coatings with tailored properties.
Composite coatings are those coatings assembled together or dispersed as minor phases (organic or inorganic) in a major component phase (inorganic or organic) to improve their individual properties. If the minor phase has nanometric dimensions, the coatings are nanocomposites. In the particular case that one or more phases are produced from molecular precursors during the nanocomposite formation and one of them is organic while the other is inorganic, we obtain hybrid inorganic–organic materials.
The aim of this focused session will show presentations, from leading researchers in both academia and industry, on all aspects related to the recent advances in the design, synthesis, and development of composite and hybrid coatings. In particular, the topic of interest includes, but is not limited to:
Focused session on tribological coatings, wear and corrosion protection
Description: Wolfgang Pauli said that “surfaces have to be the work of evil”, due to their complexity and challenges in understanding their underlying properties. Study of surfaces is even more challenging in the context of tribology, which is the science and technology of interacting surfaces in relative motion. Tribology is an exciting and highly interdisciplinary field, linked with engineering, physics, chemistry, materials science, mathematics and biology. It encompasses the study and application of friction, wear, lubrication and related surface design aspects.
Understanding the fundamentals of tribological coatings underpins the development of novel technologies across many industrial sectors including electrical vehicles, wind turbines, cutting tools, and medical implants. Recent engineering trends confirm the importance of urgent development of functional surfaces to control the energy consumption, corrosion, economic expenditure and COâ‚‚ emissions on a global scale.
In this focused session, we will discuss how surface engineering plays a key role in enabling future tribological technologies by providing smart functional surfaces with great impact on future sustainable development. Areas of particular interest will include (but are not limited to) the following topics:
Focused session on Surface nanoengineering, nanocoatings and Ultra-Thin Films
Chair: Prof. Alessandro Lavacchi, ICCOM-CNR, Italy
Description: Nanocoatings and thin films can be defined as coatings with nanoscale thickness, second-phase nano-granules distributed in a matrix, thick coatings that have nanosized grains or phases, etc. Nanocoatings have applications in many industrial fields, such as the aerospace and car industries, medical implants and instruments, metal industry for equipment and tools, chemical and food industries, etc. Depending on their application, nanocoatings may be required to be hard, to protect the underlying substrate, elastic, or, for medical applications, biocompatible. During the last years, the concept and practice of tailoring the structure and morphology of a given coating or thin film system to modify its properties has been used to add new functionalities and improved behaviour to several materials and devices. However, the development of new products and the need to enhance materials functionalities requires the optimization of the coating or thin film system to respond to the increasing demands of a targeted application. Nano-engineering of surfaces is playing a fundamental role in this particular area of research in order to develop new materials development or to modify them.
Surface nanoengineering refers to the design of physical, morphological and interfacial properties of nanoparticles or 2D nanostructured surfaces for a particular application. The surface chemistry of nanomaterials impacts an assortment of specific physical properties. Ligands and other surface molecules often play a major role in nanoparticle growth, form and crystallinity, in addition to bring new features such as (bio)chemical functional moieties, new interactions with the surrounding medium and adjusting the hydrophilic/lipophilic balance. Complex nanoparticle morphologies such as stars, core-shell, patchy and Janus nanoparticles are then possible
This session will be dedicated to advanced methods of vapor deposition and surface nano-engineering, as well as to nanoscale methods of materials characterization. It will also cover the nanoscale surface modification strategies addressing critical issues in fields related to nanotechnologies such as biomaterials, nanomedicine, plasmonics, metamaterials, energy harvesting, nanoelectronics, spintronics, and smart materials, etc.
Areas of particular interest will include, but not limited to, the following topics:
Focused session on Plasma surface engineering
Keynote speakers :
Description: Surface engineering plays an important role in all kinds of applications in modern science and engineering. Among the surface engineering techniques, plasma surface engineering has been one of the most important and versatile technologies for many years and is still growing rapidly. Plasmas are widely used to modify surface properties without changing the bulk properties. Surface plasma modification permits the change of the intended use of a material or improving its functionalities by introducing new chemical and physical properties on the surface.
With the development of engineering and science on the micro/nano scale, precise control of the surface chemical properties and of the morphological properties is becoming increasingly critical in both fundamental scientific research and applied engineering applications, such as energy, environment, biomedicine, food, etc. Successful plasma process applications include adaptive tribology coatings working at high temperatures or the surface treatment of polymer-based nanoparticles. Another interesting area is hybrid technologies. In this case, plasma technologies can complement or facilitate the application of already-established methods. For example, plasma cleaning prior to bonding and colouring, increasing adhesion between reinforcements and the matrix in composites, or the coating of materials made using additive manufacturing.
Plasma technologies have become then a part of industrial applications that replace or compete with standard technologies. Their potential is expanding thanks to new plasma sources and new techniques. This opens new areas where these technologies have a potential for future application
The aim of this focused session is to present the recent theoretical, experimental, and modelling studies, which would lead to a more wide-spread application of plasma surface engineering. In particular, the topics of interest include, but are not limited to:
Focused session on Corrosion and anti-corrosive coatings
Description: Corrosion is a global issue, which challenges a wide range of industrial sectors. It leads to high economic losses of 3–4% of the GDP of an industrialized country year by year. Adequate corrosion protection is therefore essential in many applications. Among others, coatings are by far the most important technology for the corrosion protection of metallic surfaces. In recent years, they gained a deeper understanding of the mechanisms of protective action and corrosion mechanisms of and under protective coatings. Durable and active coatings are some of the most frequently used and effective methods for corrosion protection.
The rise chemical nanotechnology has also fostered the development of hybrid or inorganic sol-gel coatings, as well as nanoparticles and nanocapsules to be used as fillers in coating systems. This has also led to the development of novel self-healing and smart coatings.
This session will focus on the improved anticorrosion properties of metallic, nonmetallic, and composite coatings using different engineering approaches to increase their durability in various demanding applications. It will cover the different aspects of processes, including physical and chemical vapor deposition, atomic layer deposition, thermal and plasma spraying, directed energy techniques, wet chemical and electrochemical processes, and techniques based on nanotechnology. It will provide comprehensive insight on corrosion resistance, mechanical properties, and surface and interface characterisation, with emphasis on enhanced functional performance for different applications. In particular, the topics of interest include, but are not limited to:
Focused session on Interface and interaction science, adhesion and Adhesives

The session topics are as follow:
Focused session on Biointerfaces and Bioactive coatings
Description: In addition to meeting the minimal requirement of biocompatibility, advanced biomaterials have acquired functions, allowing them to directly or indirectly influence specific biological environments. These modifications of biomaterials are generally achieved by establishing an interface layer, i.e., a biointerface coating, to deliver the desired functions. The design of a successful biointerface usually depends on criteria such as controlled presentation of functional biomolecules on the surface, low nonspecific protein adsorption, responsive actions toward external stimuli, multifunctionality, compatibility with micro- to nanofabrication, surface morphology or microstructures, biodegradability, and physical to chemical gradients. Many promising approaches have been realized by existing surface modification technologies based on both physical and chemical methods from basic self-assembly of molecules to top–down construction of bulk materials. Numerous methods exploit a complimentary and/or combinatorial strategy, paving the way to advanced and effective functional and bioactive coatings for prospective biomaterials. The most recent advances in fundamental studies, nano-bio material synthesis and biodevice design will be also presented, offering unique opportunities for dissemination and synergy development.
Recently, advanced methods for nanomaterial synthesis and modification have enabled new tools for regulating biomolecule conformation and cell adhesion at surfaces with nanoscale resolution through the control of topography, chemistry and morphology. Recent progress in selective surface modification of nanostructures and the integration of tools from synthetic biology and electrochemistry have contributed to the creation of tailor-made biointerfaces. In particular, the topics of interest include, but are not limited to:
