In March of this year, Iswaran was handed eight additional charges that allege he obtained items such as a Brompton bicycle, a set of golf clubs and whisky from another figure: construction company boss Lum Kok Seng.

Mr Lum’s company is involved with a number of government infrastructure projects around Singapore, which were awarded while Iswaran was Transport Minister.

The Times reached out to Wade’s attorney, Tracy Lum, for comment but did not receive a response before press time.

Asst Prof Lum's team aimed to sidestep these challenges by integrating catalyst design with electrolyte selection.

"We found that integrating acidic electrolytes with this composite system significantly suppresses the undesired side reactions from oxygen impurities in flue gas," explained Asst Prof Lum.
