Electrochemical techniques for uranium extraction from water

Chemical Engineering Journal
Electrochemical removal of uranium from water is an emerging topic that addresses the treatment of drinking water, remediation of contaminated sites, and mining from seawater. Electrochemical strategies compare favorably to conventional processes, such as adsorption and coagulation/flocculation, with advantages in speed and efficiency, materials ...

Appraisal of Six Natural Mica Reference Materials for In Situ Rb‐Sr Geochronology

Geostandards and Geoanalytical Research, EarlyView.
Key Points Evaluated six natural mica reference materials for in situ LA‐ICP‐MS/MS Rb‐Sr geochronology using geochemical, microstructural and isotopic characterisation. Identified robust primary reference materials: Mount Dromedary biotite (99.37 Ma) and Mica‐Fe biotite (307.75 Ma). La Posta biotite and Högsbo muscovite are suitable secondary reference

Melanoma and Other Melanistic Lesions in Brown Bullhead Ameiurus nebulosus From Waterbodies in the Northeastern United States and Canada: Identification of Risk Factors

Journal of Fish Diseases, EarlyView.
ABSTRACT Melanistic lesions, including non‐raised black areas due to proliferations of melanocytes and melanomacrophages in the dermis and epidermis, as well as raised black areas consistent with melanoma, are described in brown bullhead (BBH) Ameiurus nebulosus from three water bodies in the northeastern United States and Quebec, Canada.

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.

Enhancement of Extraction of Uranium from Seawater

, 2016
Even at a concentration of 3 μg/L, the world’s oceans contain a thousand times more uranium than currently know terrestrial sources. In order to take advantage of this stockpile, methods and materials must be developed to extract it efficiently, a difficult task considering the very low concentration of the element and the competition for extraction by

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 ...

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 ...

Sequencing of the rus gene before and after the mutation with DES in the bacterial Acidithiobacillus sp. FJ2

یافته‌های نوین در علوم زیستی, 2019
In Acidithiobacillus ferrooxidans, the proteins present in the electron transfer pathway cause ferrous iron oxidation which leads to uranium extraction. The relationship between gene sequence and uranium extraction has not been investigated yet. Based on
