Surface Treatment Engineering Lab
Machine-translated · View original
A lab that creates materials, from a new titanium smelting process to fuel cells.
AboutAbout the lab
Making metals and creating energy materials.
The Surface Treatment Engineering Lab studies new smelting processes that produce metals such as titanium at low cost, as well as materials for fuel cells.
The lab develops methods for producing and recycling metals using chemical reactions in molten metals and molten salts, electrolysis, and related techniques.
Combining experiments with first-principles calculations and machine learning, the lab investigates how ions move through solids and searches for new energy materials.
The lab is also known as the Uda Lab, and it publicly releases computational software developed in the lab.
Key terms
- Smelting
- Extracting metal from raw materials such as ore and increasing its purity
- Molten salt
- A salt such as magnesium chloride melted at high temperature into a liquid. It is used for electrolysis and other processes
- Proton conduction
- The movement of hydrogen ions (protons) through a solid, carrying electric charge

ResearchResearch themes
The lab works on a new titanium smelting process, fuel cells that operate at intermediate temperatures, and efficient searches for solid state ionics materials. Its research combines experiments with computer simulation.
*Illustrative imageA new smelting method for producing titanium at low cost
Titanium is a light, strong, and corrosion-resistant metal, but smelting and processing it takes a long time and makes it expensive. The lab studies an original smelting method that uses molten bismuth and magnesium, as well as a method that produces titanium plates and foils directly by electrolysis of molten salt.
*Illustrative imageIntermediate-temperature fuel cells using proton conductors
Using a proton-conducting electrolyte that works well at 400 to 600°C could make it possible to build fuel cells that do not need expensive platinum catalysts. The lab studies materials such as barium zirconate, aiming to give fuel cells higher performance and greater durability.
*Illustrative imageSearching for ion-conducting materials with computation and machine learning
The lab has developed a method that combines first-principles calculations with Bayesian optimization to predict, accurately and with little computation, how easily ions move in a solid. The aim is to find new solid state ionics materials from large amounts of materials data.
