Topic
Literature Review on the Production of Titanium Powder for Additive Manufacturing from Scrap Using the HDH Process
Background
Recycling titanium scraps through hydrogenation offers a sustainable approach to repurpose valuable material for additive manufacturing applications. The hydrogenation-dehydrogenation (HDH) process is central to this effort, allowing titanium scraps to be converted into usable powder for 3D printing and other AM techniques.
Job Definition
Conduct an extensive literature review covering the hydrogenation-dehydrogenation process as applied to titanium scraps for recycling. The review will explore key aspects such as hydrogen embrittlement mechanisms, powder morphology and quality requirements for AM, and comparative performance of recycled HDH powder Compile findings into a structured report, identifying the key challenges and benefits of using recycled titanium in AM.

M.Sc. Zixi Gao
Background
Due to the noble nature of gold, targeted recovery from e-waste is a challenge due to the higher reactivity of other metals. Current hydrometallurgical approaches for gold recovery from PCBs always require several steps, resulting in losses. The aim of this study is to find a direct leaching method for the recovery of surface gold.
Job Definition
