1. Photocatalysis beyond conventional precious metal complexes
Abstract : Precious metals, e.g. Ru and Ir, are expensive, scarce and non-renewable resources. As oppose to many renewable resources, these cannot be deliberately produced wherever one wishes. READ MORE

2. Functionalized mesoporous carbons as non-precious metal fuel cell catalysts
Abstract : Fuel cells allow for clean and efficient chemical to electrical energy conversion. However, their high price significantly limits the market viability of the technology. This is to a large part due to the high cost of the precious metals used in most fuel cell catalysts. READ MORE

3. Sustainable Recycling of Spent Lithium-ion Batteries : An In-situ Approach for Recovery and Alloying of Valuable Metals
Abstract : A large number of Li-ion batteries used today will reach their End-Of-Life (EOL) in a few years. After their EOL, the recovery of their precious elements is required. By applying physical separation, a fraction with fine particle size is left behind which is known as Black Mass (BM). READ MORE

4. Mechanical recycling of consumer electronic scrap
Abstract : Consumer electronic equipment (brown goods), such as television sets, radio sets, and video recorders, are most common. However, recycling of consumer electronic scrap is only beginning. READ MORE

5. Structure, dynamics and reactivity of low-oxidation state iron complexes in solution studied by ab initio molecular dynamics simulations and advanced quantum chemistry calculations
Abstract : Third row (3d) metals, such as iron have become a candidate for a broad class of photocatalysts that have a large abundance on Earth and a low toxicity to humans and the environment. Unlike many commonly used photocatalysts that contain expensive precious metals, iron is cheap. READ MORE
