Acute and Chronic Toxicity of Sediments Containing Platinum and Palladium on Freshwater Benthic Organisms Chironomus riparius and Hyalella azteca

Journal of Applied Toxicology, EarlyView.
ABSTRACT The expanding demand for platinum group elements (PGEs) in industrial and medical applications has led to their increasing accumulation in aquatic sediments. However, their ecological impacts remain poorly understood, particularly for sediment‐dwelling invertebrates. This study assessed the toxicity of platinum (Pt) and palladium (Pd) across a

Toward the Development of a Uranium-Based Redox-Flow Battery. [PDF]

ChemSusChem
The first all‐uranium‐based electrochemical cell has been realized using simple [UIV/V(tBuacac)4]0/+ and [UIII/IV(N(SiMe3)2)4]–/0 complexes, readily available in convenient, scalable syntheses, as anolyte and catholyte couples. Operating at a cell potential of 2.2 V with a projected energy density of 0.357 Wh kg–1, this system establishes a foundation ...

Shield materials recommended for space power nuclear reactors [PDF]

Lithium hydride is recommended for neutron attenuation and depleted uranium is recommended for gamma ray attenuation. For minimum shield weights these materials must be arranged in alternate layers to attenuate the secondary gamma rays efficiently.

Healing Beams: Radiation and Radiotherapy in Novels, Poems, Music, Film, Painting

Journal of Medical Radiation Sciences, EarlyView.
Radiation and radiotherapy are perceived by patients and the general public as mysterious, dangerous and healing. The image of radiation and radiotherapy can be analysed by studying novels, poems, music, film and painting. Our paper reviews how radiation and radiotherapy are perceived by patients, the general public, as reflected in various art genres.

Cavity temperature and flow characteristics in a gas-core test reactor [PDF]

A test reactor concept for conducting basic studies on a fissioning uranium plasma and for testing various gas-core reactor concepts is analyzed. The test reactor consists of a conventional fuel-element region surrounding a 61-cm-(2-ft-) diameter cavity ...

Thermochemically Treated Sewage Sludge Ash From Pilot‐Scale Production as P‐Fertilizer for Spring Wheat and Maize in Different Soil Conditions

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background P‐fertilizers made from sewage sludge ash (SSA) may be suitable substitutes for rock phosphate (RP)‐based fertilizers and contribute to sustainable use of waste. In this context, the thermochemical AshDec treatment of SSA (TC‐SSA) has been continuously improved and has emerged as a possible method to produce plant‐available and low ...

Geological characteristics of neoproterozoic motianling granitic pluton hosting uranium mineralization in North Guangxi, China: Insights from biotite chemistry

Frontiers in Earth Science
The Motianling pluton represents a characteristic U-bearing granite pluton in South China. Biotite serves as an indicator for the mineralization of metals such as Cu, Sn, and W in granite. Previous studies have extensively investigated the U metallogenic

Return to baseline arsenic concentrations after 1 year on gluten‐free diet in children with celiac disease: A prospective cohort study

JPGN Reports, EarlyView.
Abstract Objectives Lifelong adherence to a gluten‐free diet (GFD) is the primary treatment for celiac disease (CeD). Concerns have been raised about increased exposure to contaminants in a GFD because rice, which naturally bioaccumulates arsenic and other environmental contaminants, is commonly used as a substitute for gluten.

Joint and Rapid Determination of 210Pb-210Bi-210Po in Rock, Soil and Sediment Samples by Constant Temperature Spontaneous Deposition on Cu-foil with Gross α and Gross β Counting

Yankuang ceshi, 2013
Measurement techniques of uranium series nuclides 210Pb, 210Bi and 210Po are relatively independent at present for most cases, and there are still some technical issues that need to be overcome.
