To address these challenges, the researchers conducted a dual modification of lignin's chemical structure and physical form. They grafted methylene bis-benzotriazolyl tetramethylbutylphenol (MBBT ...

Despite its abundance, lignin's complex structure makes it difficult to convert ... the catalytic system selectively cleaves chemical bonds in lignin models, producing a variety of value-added ...

so today Xiao’s team looks more closely at lignin chemical structures. “The chemical changes during pyrolysis of lignin were very little understood,” he explains. In 2016, his team found ...

"Strategies for using lignin involve a combination of chemical and biological processes," says Associate Professor Stephen Bell, from the University's School of Physics, Chemistry and Earth Sciences.

Although the components of wood – cellulose and lignin – are exceedingly cheap and plentiful, combining these into a wood-like structure is not straightforward, despite many attempts to make ...
