内容简介：

This lecture will feature some research and development work conducted and led by the author in the field of materials processing and process control at elevated temperatures. Subjects to be addressed are:

• The FFC-Cambridge process is a generic molten salt electrolytic method that makes possible the direct conversion of metal oxides into the corresponding metals and alloys through the cathodic polarisation of the oxide in a molten salt electrolyte based on calcium chloride. An introduction into the FFC process will be given, discussing its invention, the underlying scientific fundamentals, the identification of the key process parameters, and some applications.

• Nano-structured carbon materials can be produced by the direct conversion of graphite into nanocarbon via the intercalation of lithium from molten lithium chloride. The experimental studies will be presented that have enabled the preparation of gramme quantities of nanocarbon material with nanotube contents as high as 70 to 80%. Especially highlighted will be the preparation of a new anode material, based on tin-filled nanocarbon, for lithium ion battery anodes.

• The quantitative determination of the hydrogen concentration in aluminium melts is an important metallurgical technology, as the hydrogen content needs to be monitored and controlled to ensure high-quality pore-free casts. The research and development programme will be summarised that has finally led to a novel, and now fully commercialised, solid state electrochemical hydrogen sensor for molten aluminium and its alloys.

主讲人简介：

Carsten Schwandt graduated with a Master’s Degree in Chemistry from Braunschweig University of Technology and earned a Doctorate Degree in Natural Sciences at the Max-Planck-Institute for Solid State Research Stuttgart. In 1998, he joined the Department of Materials Science and Metallurgy at the University of Cambridge, where he held various research and teaching positions. In 2013, Carsten became the National Chair Professor of Materials Science and Metallurgy of the Sultanate of Oman, based at the University of Nizwa. Carsten is also a Distinguished Visiting Fellow at his previous affiliation in Cambridge.

Carsten has developed a diverse research portfolio in the realms of sustainable processing and energy materials. His specific areas of interest are the development of molten salt processes for the extraction of reactive metals, synthesis of high-temperature materials, recycling of strategic metals and production of nanoscale carbon, as well as the synthesis, characterisation and evaluation of materials for application in devices such as fuel cells, batteries, supercapacitors, solar cells and electrochemical sensors. He is presently heading a ten-strong research group including two assistant professors.

Carsten has acquired considerable experience in industrial liaising and technology transfer, has one commercialised technology in the area of electrochemical sensors, and is involved in two other commercialisation efforts. He holds one directorship and is a consultant to several spin-out companies. Carsten is a member of four professional bodies and serves on three committees. He teaches thermodynamics, electrochemistry and materials chemistry.
