Photoisomerization-mediated tunable pore size in metal organic frameworks for U(VI)/V(V) selective separation

Nature Communications
Selective extracting uranium from seawater is quite challenging, particularly the presence of vanadium, which poses a significant obstacle for most amidoxime absorbents.

The Origins of Ploem's Filter Cube: A Pandora's Box

Journal of Microscopy, EarlyView.
Abstract Ploem's filter cube, central to modern epifluorescence microscopy, integrates three matched optical components: an excitation filter, an emission filter, and a dichroic mirror. Together, these elements enable the separation of excitation and emission light paths, producing high‐contrast fluorescence images.

Market Power in Uranium Enrichment [PDF]

Four firms dominate the international uranium enrichment market. Two reasons for this industrial concentration are (1) enrichment capacity can be used to make nuclear weapons, and hence its spread has been controlled through many mechanisms, including ...

A New Comprehensive Model to Simulate and Optimize Fluid Flow in Complex Well‐Formation System for In Situ Leaching Uranium

Energy Science & Engineering
In situ leaching (ISL) is an important method for green and efficient development of sandstone‐type uranium ore. It achieves ISL of uranium through the deployment of injection and extraction vertical well patterns.

Nationalism and Education in the Arctic: A Study of Greenland in the Context of the Kingdom of Denmark

Nations and Nationalism, EarlyView.
ABSTRACT This article analyses the coconstitution of nationalism and education in Greenland (Kalaallit Nunaat) within the Kingdom of Denmark. Drawing on Ernest Gellner, Benedict Anderson, Michael Billig and Siniša Malešević, it argues that schooling standardises language, history and civic repertoires, thereby fabricating the modern national subject ...

Dual conversion pathways for efficient electrochemical extraction of uranium

Nature Communications
The electrochemical extraction of uranium (EEU) from wastewater is of promise to ensure the sustainable development of nuclear power, of which the practical application is limited due to the single uranium species conversion pathway.

Alternative approaches to dryland reclamation enhance vegetation cover and soil stability at a former uranium mine

Restoration Ecology, EarlyView.
Abstract Introduction Conventional reclamation methods to recover dryland ecosystems after mineral extraction often have low success. Alternative reclamation techniques may help overcome the many challenges to establishing persistent native vegetation and stable soils.

Diagenetic controls on porosity evolution and pore type organisation in microporous carbonate rocks: Evidence for mesogenetic porosity formation

Sedimentology, EarlyView.
ABSTRACT Microporous carbonate rocks typically record complex diagenetic histories driven by microbial activity and fluid interactions within multiple diagenetic environments. The relative roles of meteoric and burial diagenetic processes in pore evolution remain debated, particularly within Cretaceous carbonate systems of the Middle East, as does the ...

Outcrop and subsurface characterisation of a mixed tidal and wave‐influenced coastline (Triassic Red Beds, SE Spain)

Sedimentology, EarlyView.
ABSTRACT Paralic depositional systems are complex and heterogeneous sedimentary environments, presenting challenges for predicting reservoir architecture and connectivity. Their stratigraphic and facies variability arises from the dynamic interplay between fluvial, tidal and wave processes, and their sensitivity to sea‐level fluctuations, sediment ...
