Interaction between Uranyl Cations and Layered Double Hydroxide Nanoparticles: Implications for Nuclear Wastewater Management.

Effective uranium (U) capture is required for the remediation of contaminated solutes associated with the nuclear fuel cycle, including fuel reprocessing effluents, decommissioning, or nuclear accident cleanup. Here, interactions between uranyl cations (UO ) and a Mg-Al layered double hydroxide (LDH) were investigated using two types of uranyl-bearing LDH colloids. The first (ULDH) was synthesized by coprecipitation with 10% of Mg substituted by UO .

A self-assembled metallo-macrocycle two-qubit spin system.

A self-assembled, charge-neutral dicopper(II) metallo-macrocycle with a near degenerate singlet-triplet ground state is a prototype molecular two-qubit system. The weakly-coupled spin centres delivered a long phase memory time of 5.4 μs, and each spin can be selectively switched using an applied potential providing a convenient means to modulate the quantum levels.

PET/CT-derived coronary calcium score may predict cardiac complications in anthracycline-treated lymphoma patients.

Anthracycline-mediated cardiotoxicity is a common concern following lymphoma therapy, particularly in patients with high cardiovascular risk (CVR). In non-cancer populations, coronary artery calcium scoring (CACS) effectively identifies individuals who may benefit from aggressive CVR modification to lower the risk of cardiovascular events. Emerging evidence suggests that CACS can also predict cancer therapy-related cardiotoxicity, potentially identifying candidates for cardioprotective strategies.

Tobacco, nicotine, and cannabis use and exposure in an Australian Indigenous population during pregnancy: A protocol to measure parental and foetal exposure and outcomes.

Background: The Australian National Perinatal Data Collection collates all live and stillbirths from States and Territories in Australia. In that database, maternal cigarette smoking is noted twice (smoking <20 weeks gestation; smoking >20 weeks gestation). Cannabis use and other forms of nicotine use, for example vaping and nicotine replacement therapy, are nor reported.
