Uranium extraction: Fuel from seawater

Nature Energy, 2017
There are over four billion tonnes of uranium in the oceans that could be harvested for nuclear fuel, but current capture methods have limited performance and reusability. Now, an electrochemical method using modified carbon electrodes is shown to be promising for the extraction of uranium from seawater.

Electrospun fibrous sorbents for the removal of uranium and americium from aqueous media

Polymer International, EarlyView.
Polymethacrylate‐based electrospun microfibers with tertiary amino functionalities are evaluated as adsorbents for U‐232 and Am‐241 in both simplified and complex (seawater) water matrices, highlighting their ability for efficient actinide removal. Abstract Polymethacrylate‐based electrospun microfibers containing tertiary amino functionalities were ...

177Lu‐labeled amidoxime‐functionalized biodegradable microspheres for transarterial radioembolization of hepatocellular carcinoma

Precision Radiation Oncology, EarlyView.
Scheme 1. Schematic illustration of the synthesis and therapeutic evaluation of PLA‐g‐PAO microspheres (PLA‐g‐PAO‐Ms). Monodisperse PLA microspheres (PLA‐Ms) were initially fabricated via microfluidic technology. Surface grafting of acrylonitrile monomers was subsequently achieved through radiation‐induced graft polymerization, followed by ...

Integrated Alpha–Gamma Radiation Exposure From Natural Radionuclides in Cement and Gypsum Production: Implications for Occupational Lung Cancer Risk

Environmental Toxicology, EarlyView.
ABSTRACT Natural radionuclides in cement and gypsum production materials pose significant risks of occupational radiation exposure that are not well documented in Iraqi Kurdistan. This study quantifies alpha and gamma radiation levels from naturally occurring radioactive materials, specifically 222Rn, 238U, 232Th, and 40K, in cement and gypsum samples ...

Theoretical Insight Towards Uranium Extraction from Seawater [PDF]

, 2018
Uranium’s economical consumption is based on the industrial nuclear fuel cycle. Today there remains 4-6 million tons of terrestrial uranium in Earth’s ores. However, as the projected population is estimated to double by 2040, current uranium reserves are

Conditions and timing for the precipitation of early marine diagenetic dolomite in the Triassic Dolomia Principale (northern Italy)

Sedimentology, EarlyView.
ABSTRACT Thermodynamic constraints and empirical evidence often suggest that fabric‐retentive replacement dolomites are stable carbonate minerals that preserve ancient seawater properties. This study evaluates this hypothesis by examining the Upper Triassic Dolomia Principale in Northern Italy.
