Thin-film photovoltaic technologies are gaining momentum over the currently dominated crystalline silicon technologies. In addition to the competitive prices, flexible thin-film technology especially has the added advantage such as in building integrated photovoltaics (BIPV) due to its flexibility and light weight. HyET Solar B.V. is a company...

The project site in Anderlecht, Belgium exists a fragmented urban fabric in terms of morphological evolution in the post-industrial period, functional mix of the urban plot, connection with the immediate urban grains and the ephemeral state of ownership of spaces around the site. However, the nomadic site actors practise informal ‘urban mining’...

The future of our energy supply cannot continue to depend on the use of exhaustible fossil fuels. The successful transition to a society powered by renewable energy sources is one of the major challenges our current generation faces. Renewable systems will only fully establish themselves if high conversion efficiencies can be obtained at a...

Thin film solar cell technologies are gaining more favour over first generation PV technologies such as monocrystalline silicon PV modules. This is due to their special characteristics such as lightweight, flexibility and reduced resource consumption. HyET Solar is a Netherlands based company that makes thin film amorphous silicon modules using...

Garg, Vishant (author)
Al-Li alloys were introduced for the use in aerospace applications due to its many advantages over steel such as its low density, good thermal and electrical conductivity and corrosion resistance of these alloys. The current generation of Al-Li alloys were developed to replace the currently used AA2024 alloy in commercial airframes, military and...

Meeusen, M. (author)
The corrosion protection of metallic substrates with corrosion inhibitors, either in solution or dispersed in a coating formulation, has been the focus of many research topics for many decades and has intensified in recent years even more with industry moving away from hexavalent chromium (Cr(VI))- based corrosion inhibitors. While mainly...

Olgiati, Matteo (author)
Salts of trivalent cerium (Ce(III)) are known to successfully hinder localised corrosion phenomena typical of aerospace aluminium alloys by forming a thin passivation layer on top of the corrosion-active intermetallic phases. This is generally observed to happen when the alloy is under immersion conditions in a solution containing Ce3+ ions....

Hexavalent chromium has been the industry standard for corrosion protection for many years. Its unsurpassed active corrosion inhibiting capabilities, its incredible versatility and its economic benefits made it a popular all-rounder. Nowadays the widely known toxic and carcinogenic nature have restricted its use within the European Union. More...

A modulated synthesis approach based on the chelating properties of oxalic acid (H<sub>2</sub>C<sub>2</sub>O<sub>4</sub>) is presented as a robust and versatile method to achieve highly crystalline Al-based metal-organic frameworks. A comparative study on this method and the already established modulation by hydrofluoric acid was conducted...

Dealloying is involved in materials science responsible for fabrication of nanoscale structures beneficially but for corrosion degradations detrimentally. Detailed understanding related to the latter is critical for designing corrosion-resistance alloys and dedicated inhibition systems. Thus, direct nanoscopic observations of nano-structural...

Nanoscopic characterization of heterogeneous intermetallic particles (IMPs) which microstructurally and compositionally evolve during local corrosion is crucial in unravelling the mechanisms and sequence of initial and local corrosion events. Herein, we study site-specific initiation events focused on microscopic constituent intermetallic...

There is a growth in the use of composites for the new generation of wide-body aircraft such as the Boeing 787 and Airbus A350. This shift from using aluminium as the primary material is motivated by the benefits of using composites in design, manufacturing and operations. Composites offer the aircraft manufacturer the ability to create more...

Context<br/> The “take-make-dispose” linear model has proven to be highly unsustainable during the past decades. A circular economy has emerged as a model that is restorative by design, and a response towards the high material and energy intensive linear model. However, a transition to a circular built environment implies a radical change in...

Reukema is the biggest non-ferrous trader in the Netherlands. They want to investigate the possibility of sorting aluminium in a robotic system. Aluminium is one of the most used materials worldwide. Demands for aluminium are ever increasing. Recycling scrap is needed to keep up with the demand. An important step in the recycling process is the...

For decades, scientists and engineers are searching for a safe and environmentally friendly alternative for the toxic chromate corrosion inhibitors in active protective coatings for the protection of aerospace aluminium alloys. In this search many different compounds have been investigated as leachable corrosion inhibitor, but no alternative...

Chemical throwing power, being the distance over which an inhibitor is able to protect a defect effectively, is an important parameter for active protective coatings. This study investigates the chemical throwing power of lithium-based leachable corrosion inhibitors exhibiting different leaching kinetics, from coatings at different inhibitor...

This study presents the active protective properties of lithium-leaching coatings for a range of aluminium alloys. Coatings with and without lithium carbonate as leachable inhibitor were applied on the aluminium alloys, artificially damaged and exposed to the neutral salt spray. A combined approach of scanning electron microscopy and...

A study has been carried out to understand the modification of alumina inclusions in Al-killed high sulphur steel with calcium treatment. For calcium treatment to be effective, a general practice is to desulphurise the steel to prevent the formation of solid CaS inclusions that are harmful to steel quality and final properties. To avoid this...

Organic primer coatings loaded with environmentally harmful Cr(VI) corrosion inhibitive pigments still play an important role in corrosion protection of aluminium alloys for the aerospace industry. A potential “green” alternative coating system has recently been developed, loaded with lithium salt corrosion inhibitors. Under exposure to...
