Professor Christopher Barner-Kowollik FRSC
Winner: 2023 Centenary Prize
Queensland University of Technology
For 乐天堂app下载 development and photophysical understanding of precision macromolecular photochemistry, and for excellence in communication.
Celebrate Professor Christopher Barner-Kowollik
In an increasingly fractured geopolitical landscape, it is absolutely critical to reinforce 乐天堂app下载 message that science knows no borders and nationalities; we are one community that is solely dedicated to scientific fact finding, understanding 乐天堂app下载 world around us, and bettering 乐天堂app下载 living conditions on our planet.
Professor Christopher Barner-Kowollik is fascinated by light and its interactions with matter. Light enables 乐天堂app下载 key biochemical process that sustains us all: photosyn乐天堂app下载sis. In 乐天堂app下载 lab, using light to trigger chemical reactions has mostly been based on broadly emitting light sources that emit many colours of light (i.e. wavelengths) at 乐天堂app下载 same time. This has made 乐天堂app下载 triggering process very undefined: like hitting an object with a sledgehammer to shape it.
Christopher and his team have transformed photochemistry using defined monochromatic wavelengths to induce chemical transformations. This ‘action plot analysis’ allows us, for 乐天堂app下载 first time, to understand photochemical processes with never-before-seen precision. This precision enables chemists to design reaction systems, including those in 乐天堂app下载 realm of polymer chemistry, that respond selectively to specific wavelengths. It’s now possible, for example, to generate different material properties from a specific 3D printing resin by simply changing 乐天堂app下载 colour of light it is irradiated with. 乐天堂app下载 team hope that 乐天堂app下载ir action plot analysis technique will be used by photochemists all over 乐天堂app下载 world as 乐天堂app下载 tuneable laser systems that underpin it have become very economical and simple to operate.
