The European Green Deal aims to achieve the climate neutrality in Europe by 2050; furthermore, an intermediate target fixes a first reduction of greenhouse gas emissions by minimum 55% within 2030, with reference to 1990 levels. In these contexts, and in particular in hard-to-abate processes as steelmaking, hydrogen could be a key instrument to ach...

LCA (Life Cycle Assessment) is an established method to measure the economic, social and environmental impact of a good or a service, with particular attention to its value chain or its life cycle. However, it is heavily biased in favor of environmental issues, actually environmental burdens or stressors: the economic dimension is only tackled in L...

The Ni-Mo coating as a replacement for hard chrome plating has gained popularity due to its low environmental pollution. This thesis aims to investigate the characteristics of a Ni-Mo alloy brush coating on a 45# steel base material using the brush plating process. The composition of the plating solution was varied to analyze the effects on the sur...

Laser Powder Bed Fusion (L-PBF) is an additive manufacturing process, which allows to produce metallic parts layer by layer. The reuse of the powder is critical for cost part. The reuse can modify the powder and thus the printed parts properties. This study is focused on a severe reuse of 6061-Zr by analyzing the physico-chemical features of the po...

Le développement de plastiques biosourcés est une alternative intéressante pour diminuer la dépendance au pétrole et pour limiter l’effet des plastiques pétrosourcés sur l’environnement conduisant à des effets délétères sur les écosystèmes terrestres et marins. En parallèle du développement de plastiques biosourcés, il est important de se préoccupe...

In this work, we examine the performance of novel dyes as photosensitizers in dye-sensitized solar cells. We use density functional theory calculations to explore the energy levels, absorption wavelengths, and photovoltaic characteristics of these dyes. The calculated energy levels show appropriate alignment with electron transport layers, guarante...
