3D continuum percolation approach and its application to lava-like fuel-containing materials behaviour forecast [PDF]

Condensed Matter Physics, 2009
The paper is devoted to the theoretical study of elementary permeable objects percolation and its application to real physical objects. Spheres and isotropic oriented capped sticks were chosen as elementary geometrical objects for percolation simulation,

Chemical state mapping of simulant Chernobyl lava-like fuel containing material using micro-focused synchrotron X-ray spectroscopy. [PDF]

J Synchrotron Radiat, 2021
Uranium speciation and redox behaviour is of critical importance in the nuclear fuel cycle. X-ray absorption near-edge spectroscopy (XANES) is commonly used to probe the oxidation state and speciation of uranium, and other elements, at the macroscopic and microscopic scale, within nuclear materials.

Investigating the microstructure and mechanical behaviour of simulant “lava-like” fuel containing materials from the Chernobyl reactor unit 4 meltdown [PDF]

Materials & Design, 2021
Decommissioning of the damaged Chernobyl nuclear reactor Unit 4 is a top priority for the global community. Before such operations begin, it is crucial to understand the behaviour of the hazardous materials formed during the accident.

Synthesis of simulant ‘lava-like’ fuel containing materials (LFCM) from the Chernobyl reactor Unit 4 meltdown [PDF]

MRS Advances, 2016
A preliminary investigation of the synthesis and characterization of simulant ‘lava-like’ fuel containing materials (LFCM), as low activity analogues of LFCM produced by the melt down of Chernobyl Unit 4. Simulant materials were synthesized by melting batched reagents in a tube furnace at 1500 °C, under reducing atmosphere with controlled cooling to ...

Charge accumulation and electric fields in lava-like fuel containing materials

Nuclear Physics and Atomic Energy, 2005
The charge accumulation and electric fields due to internal radioactivity in lava-like fuel containing materials has been considered. It has been shown that macroscopic electric fields can be as large as 104 V/cm at the material surface and at the interface of a spherical inclusion - SiO2 matrix for the total activity 1 GBk · сm-3.

Monocyte‐mediated metabolic rewiring via CD31‐CD38 interactions promotes growth and drug‐resistance in multiple myeloma [PDF]

Hemasphere
Abstract Multiple myeloma (MM) cells interact with different components of the bone marrow (BM) microenvironment, which plays a critical role in MM progression and confers resistance to therapy. Here, we report that monocytes actively control MM cell metabolism by transferring mitochondria to MM cells, thereby increasing their mitochondrial content ...

Seed Thermal Response, and Morphological and Biochemical Plasticity in <i>Wigandia urens</i> as Indicators of Its Utility for Elevational and Latitudinal Assisted Migration. [PDF]

Ecol Evol
To identify the phenotypic plasticity in germination traits related to the tolerance to changes in temperature resulting from CC and improve the successful of plant cover recovery in elevational and latitudinal gradients, we assessed the amplitude and variability of phenotypic plasticity in the seed response of W.
