Students will learn how to categorize matter as either pure substances or mixtures. Students will apply tests, based on physical properties of matter samples, to determine whether a mixture is ...

Graph Neural Networks (GNN), a cutting-edge approach in artificial intelligence, can significantly improve computational calculations in heterogeneous catalysis. Researchers have made a groundbreaking ...

Professor Jian HE, from the Department of Chemistry at The University of Hong Kong (HKU), has spearheaded a research endeavour aimed at revolutionising organic synthesis. His research team has ...

Students learn to classify matter as elements, compounds, and mixtures. Matter: Classification of Matter: Students learn to classify matter as elements, compounds, and mixtures and to distinguish ...

A team of researchers reports developing a nanocrystal structure capable of controlling catalysis with the pores of a skin-like membrane that can accept or reject molecules based on their size or ...

Everything we can see and touch, and quite a lot that we can’t as well, is made of tiny particles called atoms. Some substances, like particles of this iron, contain only one kind of atom. Iron is an ...
