Metal Hydrides‐Based Hydrogen Purification Systems—A Review

MetalMat, Volume 3, Issue 1, March 2026.
Metal hydrides as an innovative means to purify hydrogen can enable new avenues in the use of hydrogen as a clean energy vector across its production methods. ABSTRACT This review investigates the critical role of purification for enabling the use of hydrogen from various production pathways.

Regularized estimation for highly multivariate log Gaussian Cox processes

, 2019
Statistical inference for highly multivariate point pattern data is challenging due to complex models with large numbers of parameters. In this paper, we develop numerically stable and efficient parameter estimation and model selection algorithms for a ...

Investigation of H-mode density limit in mixed protium–deuterium plasmas at JET with ITER-like wall

Nuclear Materials and Energy
Analysis of comparable discharges fuelled by either deuterium or protium reveals a clear relationship between the isotope mass and the H-mode density limit.

Soil Properties and Plant Species Identity Independently Influence Arbuscular Mycorrhizal Fungal Composition Across Lowland Tropical Forests

Biotropica, Volume 58, Issue 2, March 2026.
We found that plant species identity and soil properties, especially soil phosphorus availability, independently structured arbuscular mycorrhizal fungal (AMF) community composition in tropical forests across central Panama. We also found that soil nutrient availability may mediate the interaction networks between plants and AMF. ABSTRACT Plant species

Forest Reorganisation After Natural Disturbance: A Synthesis

Global Ecology and Biogeography, Volume 35, Issue 3, March 2026.
ABSTRACT Aim Natural disturbances are intensifying under global change, yet a global synthesis of their effects on forest structure and composition remains lacking. We aimed to assess the prevalence of structural versus compositional changes and to identify common post‐disturbance reorganisation pathways across forest biomes.
