Art Ragauskas has heard this maxim countless times during his career, and it gets him a little riled up every time he hears it. As the UT-ORNL Governor’s Chair for Biorefining, Ragauskas is channeling that ire into proving that the old saying’s time has come and gone.

A team of scientists from the National University of Singapore (NUS) has developed a prototype device that mimics natural photosynthesis to produce ethylene gas using only sunlight, water and carbon dioxide. The novel method, which produces ethylene at room temperature and pressure using benign chemicals, could be scaled up to provide a more eco-friendly and sustainable alternative to the current method of ethylene production.  

Pollution levels in the Indian capital this month have rivalled 1952 London, when smog killed around 4,000 people, pollution experts say. 

A new field of science is being developed by Lancaster researchers who are discovering the underlying mechanisms of interaction behind everything from the human body to climate change.

Un equipo de científicos de la Universidad Nacional de Singapur (NUS) ha desarrollado un dispositivo prototipo que imita la fotosíntesis natural para producir gas etileno utilizando solo luz solar, agua y dióxido de carbono. El nuevo método, que produce etileno a temperatura y presión ambiente utilizando sustancias químicas benignas, podría ampliarse para proporcionar una alternativa más sostenible y ecológica al método actual de producción de etileno.
