Chemicals are ubiquitous in the workplace (glues, resins, processing fluids, cleaning and bleaching agents, degreasers, paints…). They are used intentionally as substances or, more frequently, as preparations (mixtures). They may also be emitted from a process (combustion, degradation...

Functional materials are at the center of most technologies of our everyday life: cell phones, solar cells, batteries, thermoelectric devices, digital storage, catalysis, and many other applications need at least one material fulfilling a task through its intrinsic physical properties. Finding a material well-suited for a given application is far from trivial. Indeed, even though close to 300 000 crystal structures have been reported today, less than 1 percent of those materials have been characterized for any measurable property.    The mapping between crystal structures and physical properties is very far from completely known. Such mapping has to be constructed by characterizing known (or even unknown) materials. The traditional approach is to try and synthetize materials in lab conditions and measure their properties. When looking for a new material for a given application, the next step is to assess whether it is worth pursuing with this material or if another one should...

Nickel plating processes, while widely used, come with their own set of challenges, especially when it comes to upscaling from laboratory setups to larger plating cells. The NICKEFFECT project, aimed at developing Ni-alloy plated electrodes, faces not only the inherent limitations of nickel plating but also the complexities introduced by the porous structures.   Addressing Throwing Power Limitations:   One notable challenge in nickel plating processes is the limited throwing power compared to other methods, leading to edge effects with uneven deposit thickness near substrate borders. The NICKEFFECT project acknowledges this hurdle and seeks to overcome it during the upscaling process.   Managing Current Density Variations:   Ni-alloy plating introduces an additional layer of complexity, as the alloy content in the deposit strongly depends on current density. Factor in the three-dimensional structures, and you face varying current density and deposit thickness throughout the substrate. Achieving uniformity in thickness and alloy content becomes a formidable task, especially when upscaling...

Whether we realize it or not, we use Nickel every day in our lives. Nickel can be found in household appliances and products, electronics, jewelry, coins, buildings, stainless steel, magnets, and even in our bodies, as a trace element. Nickel also has several important industrial applications as a catalyst, in both oxidation and reduction reactions, used for example in oil refining and hydrogenation reactions. An important application of Nickel towards the transition to carbon-neutral energy is its catalytic activity for Hydrogen production. Can Nickel be part of the solution for clean energy production in the future?   We believe it can. Researchers involved in the NICKEFFECT project are developing Nickel-based coatings for several applications, including the catalytic production of Hydrogen. While this reaction is already applied on a commercial scale, it typically uses Platinum as the catalyst, a scarce and expensive element. Instead, the researchers involved in NICKEFFECT aim to develop Platinum-free...

Platinum is the rock star as a water reduction electrocatalyst, particularly in acidic media. However, its low abundance and high price makes it necessary to envision new platinum-free electrocatalysts. The same holds when we look at the oxygen reduction reaction side in a proton exchange membrane fuel cell. Options are not so obvious when it comes to transition metals and full replacement of platinum is often accompanied by a decrease of the catalytic activity. While some alternatives in the form of alloys or composites show promising results, their long-term durability is often compromised. Corrosion-related issues appear and profound leaching of the material catalyst is unavoidable.   Playing with the catalyst architecture while keeping its composition free from platinum is a convenient strategy to couple high electrocatalytic performance and good durability in acidic media. The introduction of porosity in the catalyst material has been the focus of intense research in the last years....

Achieving optimal efficiency in electrodeposition coating is utmost important for high-quality and high-performance outcomes across a broad spectrum of applications, including but not limited to fuel-cell, catalysis, magnetic storage devices, corrosion protection and many others. The foundation of this efficiency/performance lies in the careful selection of the right electrolyte bath and coating parameters. While the wisdom gained from experienced researchers and extensive literature reviews is undoubtedly valuable, the complexity of real-world application often necessitates a deeper exploration into the multifaceted factors that exert influence on the coating process.   Modelling, by unraveling the complex coating mechanisms across a diverse spectrum of factors, including electrolytes, concentration, working environments, equips us with the ability to assess coating efficiency and predict the highest attainable level of performance. Notably, this is accomplished without incurring extra cost and with a relatively short timeframe. The ultimate validation of modeling results comes through a comparative analysis with experimental laboratory...

The energy sector is currently experiencing a continuous and unprecedented growth. Driven by demand for cleaner, more sustainable, and efficient solutions, it has produced a critical need for the development of new materials and innovative processes. From advanced fuel cells for new-generation vehicles to highly energy-efficient magnetic devices and beyond, materials science took the central role in shaping the future of the energy landscape.    One of the fundamental challenges lying between the innovative ideas of better materials and their integration in real-world applications is a transition from laboratory-scale synthesis to industrial-scale production. While the laboratory serves as a cradle of innovation, enabling researchers to explore novel materials and processes, it operates within controlled environments, often producing small quantities for experimental purposes. Industrial-scale production, on the other hand, demands a leap from grams to tons and even megatons. This transition in scale not only strains the resources but can also impact the...
