The new research is published in Science Advances by an international team led by chemists at the University of British Columbia (UBC). "This discovery deepens our understanding of quantum fluids and could inspire more efficient hydrogen storage and transport for clean energy," says Professor Takamasa Momose, an expert on cold molecules at UBC and senior author of the paper.
