High pressure electronic transitions a pathway to high-temperature superconductivity in hydrogen
25 september 2019
An international experimental research team led by Professor Ho-Kwang Mao and Dr Cheng Ji from HPSTAR, China and a theory team led by Professor Rajeev Ahuja, Uppsala University, have used experimental research as well as theory to understand high-pressure structural phase transitions in hydrogen which could give rise to metallisation and could even result in superconductivity. The findings were published this week in the online edition of Nature.

An international research team, comprising scientists working in the Sweden, UK, USA & South Korea and led by Professor Rajeev Ahuja of Uppsala University now presents new findings for better understanding of superconducting high-pressure metal hydride systems. The study is published online in the Proceedings of the National Academy of Sciences of the United States of America (PNAS).
A touch of potassium yields better hydrogen-storage materials
15 april 2009
An international research team, including Professor Rajeev Ahuja's research group at Uppsala University, has shown that small additions of potassium drastically improve the hydrogen-storage properties of certain types of hydrogen compounds. The findings are published in the Web edition of Angewandte Chemie International Edition.
New applications for carbon nanomaterials in hydrogen storage
12 mars 2009
An international research team, involving Professor Rajeev Ahuja at Uppsala University and researchers in the USA, set out to understand the mechanism behind the catalytic effects of carbon nanomaterials. Experimental and theoretical efforts were combined in a synergistic approach and the results, published this week in the ASAP section of the journal Nano Letters, will fasten efforts to develop new catalysts.
An impossible alloy now possible
26 februari 2009
What has been impossible has now been shown to be possible - an alloy between two incompatible elements. The findings are being published in this week's edition of Proceedings of the National Academy of Science, USA.
