Biological Flora of Britain and Ireland: Geranium sylvaticum*

open access: yesJournal of Ecology, Volume 114, Issue 2, February 2026.
Geranium sylvaticum is a perennial forb of upland grasslands, woodlands and riverbanks in northern Britain, with scattered native occurrences also in Wales, central England and Northern Ireland. It has an extensive native range in Europe and Asia. The species is gynodioecious, with individual plants typically female or hermaphrodite.

Conceptual Design of a Metal Hydride System for the Recovery of Gaseous Hydrogen Boil-Off Losses from Liquid Hydrogen Tanks

open access: yesEngineering Proceedings
Liquid hydrogen (LH2) is a promising energy carrier to decrease the climate impact of aviation. However, the inevitable formation of hydrogen boil-off gas (BOG) is a main drawback of LH2. As the venting of BOG reduces the overall efficiency and implies a

A comprehensive evaluation of a novel integrated system consisting of hydrogen boil-off gas reliquifying process and polymer exchange membrane fuel cell using exergoeconomic and Markov analyses

open access: yesEnergy Reports, 2022
The price of constructing hydrogen generation units is very high and sometimes it is not possible to build them in the desired location, so the transfer of hydrogen from the hydrogen generation system to the units that need it is justified.

Seasonal analysis of boil-off gas rates in liquid hydrogen storage tank using time-series analysis [PDF]

open access: yes
The storage of liquid hydrogen (LH2) in stationary tanks poses significant challenges due to boil-off gas (BOG) losses caused by heat ingress from the external environment.

The Role of Fe(II) Minerals in Carbon Stabilization in Coastal and Estuarine Anoxic Environments

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 1, January 2026.
Abstract Fe(III) (oxyhydr)oxides are well‐known for their role in organic carbon (OC) stabilization in terrestrial soils. Coastal and estuarine soils typically act as iron sinks and receive a high input of OC. However, tidal submersion induces anoxic and reducing conditions that favor the microbial reductive dissolution of Fe(III) (oxyhydr)oxides ...

Catchment Controls on the Use of Dissolved Organic Nutrients by River Phytoplankton in the United Kingdom

open access: yesFreshwater Biology, Volume 70, Issue 12, December 2025.
ABSTRACT Dissolved organic matter (DOM) affects the structure and function of aquatic ecosystems and can supply nitrogen and phosphorus to meet the stoichiometric needs of biota. Anthropogenic alteration of the nature and rates of DOM inputs to freshwaters may be increasing the risk of eutrophication, but most of our understanding of DOM use in ...

Optimization of UA of heat exchangers and BOG compressor exit pressure of LNG boil-off gas reliquefaction system using exergy analysis

open access: yesIOP Conference Series: Materials Science and Engineering, 2015
Boil-off gas (BOG) generation and its handling are important issues in Liquefied natural gas (LNG) value chain because of economic, environment and safety reasons. Several variants of reliquefaction systems of BOG have been proposed by researchers. Thermodynamic analyses help to configure them and size their components for improving performance.
