Exact electronic states with shallow quantum circuits from global optimisation

npj Quantum Information, 2023
Quantum computers promise to revolutionise molecular electronic simulations by overcoming the exponential memory scaling. While electronic wave functions can be represented using a product of fermionic unitary operators, the best ansatz for strongly ...

Modular detergents tailor the purification and structural analysis of membrane proteins including G-protein coupled receptors

Nature Communications, 2020
Detergents are indispensable reagents in membrane protein structural biology. Here, L. H. Urner and co-workers introduce oligoglycerol detergents (OGDs) and use native mass spectrometry to show how interactions of membrane proteins with native membrane ...

Biomimetic light-harvesting funnels for re-directioning of diffuse light

Nature Communications, 2018
Sunlight harvesting and redirection is a promising concept for sustainable energy conversion, however losses have hindered progress. Here the authors construct a simple biomimetic device which minimises losses by using reservoirs of randomly-oriented ...

Strong inverse kinetic isotope effect observed in ammonia charge exchange reactions

Nature Communications, 2020
Inverse kinetic isotope effects (KIEs) are rarely observed. Here, the authors report an inverse KIE in the charge transfer reaction of $${{\rm{Xe}}}^{+}$$ Xe+ with ammonia.

Understanding the Sensing Mechanism of Rh₂O₃ loaded In₂O₃

Proceedings, 2018
The effect of Rh loading on CO sensing was studied for the case of In2O3. This was done by performing measurements with sensors based on loaded and unloaded materials that were performed at an operation temperature of 300 °C in the presence of low ...
