A cohort of persons exposed in utero due to radioactive contamination of the Techa River (Southern Urals, Russia) in the early 1950s represents a unique opportunity for studying radiation risks from chronic exposures in early life. Bone-seeking strontium radioisotopes were the main contributors to haemopoietic tissue doses received in utero from maternal ingestion of radionuclides before and du...

The distribution of divalent ions in semidilute solutions of high-molecular-mass DNA containing both sodium chloride and strontium chloride in near-physiological conditions is studied by small-angle x-ray scattering and by small-angle neutron scattering. Both small-angle neutron scattering and small-angle x-ray scattering reveal a continuous increase in the scattering intensity at low q with in...

The aim of our study was to investigate how exposure to heavy metal-rich waters from gypsum mining affects the morphology and levels of primary DNA damage in Gammarus balcanicus. Chemical analysis revealed increased concentrations of metals in water and sediment collected at a site impacted by gypsum mine wastewaters. The specimens also showed elevated total tissue metal levels when compared wi...

End-products of sulfide detoxification have been compared in three turbellarians and a gastrotrich typical of lenitic beaches with a well-developed sulfide system. Oxidation products were correlated with the oxygen concentration in the animal's habitat indicating that adaptation to life in the sulfide system involves reduction of dependency on molecular oxygen in metabolism. Archiloa wilsoni, a...

Nitrate decreases sulfide release in wastewater treatment plants (WWTP), but little is known on how it affects the microzonation and kinetics of related microbial processes within the biofilm. The effect of nitrate addition on these properties for sulfate reduction, sulfide oxidation, and oxygen respiration were studied with the use of microelectrodes in microaerophilic wastewater biofilms. Mas...

Sodium-metal sulfide battery holds great promise for sustainable and cost-effective applications. Nevertheless, achieving high capacity and cycling stability remains a great challenge. Here, uniform yolk-shell iron sulfide-carbon nanospheres have been synthesized as cathode materials for the emerging sodium sulfide battery to achieve remarkable capacity of ∼ 545 mA h g(-1) over 100 cycles at 0....

We report the synthesis of several unconventional 0-, 1- and 2-dimensional copper sulfide nanostrucutures by the chemical vapor deposition method. The key factor for morphology and structure control of a variety of copper sulfide products is the tuning of deposition and growth temperature to fit for the surface energy barriers and promote different growth directions. At a high growth temperatur...

We report the observation of vacuum ultraviolet (VUV) emission in the region 40 − 560 nm from incandescently heated atomic hydrogen and atomized strontium. Typically the emission of vacuum ultraviolet light from hydrogen gas is achieved using discharges at high voltage, synchrotron devices, high power inductively coupled plasma generators, or a plasma is created and heated to extreme temperatur...
