In-situ hydrogen wettability characterisation for Underground Hydrogen Storage

open access: yesInternational journal of hydrogen energy, 2021
Hydrogen storage in subsurface aquifers or depleted gas reservoirs represents a viable seasonal and/or long-term energy storage solution. However, currently, there is a scarcity of subsurface petrophysical data for the hydrogen system, limiting modelling

A critical review of the drilling of CFRP composites: Burr formation, characterisation and challenges

open access: yes, 2021
Burr is one of the main macro-geometrical types of damage concerning machined features of carbon fibre reinforced polymer (CFRP) composites. Even if it does usually not weaken the strength of composite materials, it is recommended to be removed.

How to differentiate a quantum stochastic cocycle. [PDF]

open access: yes, 2010
Two new approaches to the infinitesimal characterisation of quantum stochastic cocycles are reviewed. The first concerns mapping cocycles on an operator space and demonstrates the role of H\"older continuity; the second concerns contraction operator ...

On the characterisation of paired monotone metrics [PDF]

open access: yes, 2003
Hasegawa and Petz introduced the notion of dual statistically monotone metrics. They also gave a characterisation theorem showing that Wigner-Yanase-Dyson metrics are the only members of the dual family.

A Study on the Phenotypic Variation of 103 Cucumber (Cucumis sativus L.) Landraces for the Development of Desirable Cultivars Suitable for the Changing Climate

open access: yesLife, 2022
The cucumber (Cucumis sativus L.) is one of the most important vegetables in Bangladesh as well as across the globe. However, many of the important cucumber landraces have disappeared in Bangladesh due to climate change, particularly erratic rainfall ...
