The race for better electrochemical energy storage systems has prompted examination of the stability in molybdate framework (MMoO4; M = Mn, Co, or Ni) based on a range transition metal cations from both computational and experimental approaches. Molybdate materials synthesized with controlled nanoscale morphologies (such as nanorods, agglomerated nanostructures, nanoneedles Ni elements, respectively) have been used cathode hybrid systems. data confirms that MnMoO4 crystallized β-form...
Titanium dioxide (TiO2) has often served as a model substrate for experimental sorption studies of environmental contaminants. However, various forms Ti-oxide have been used, and the different properties these materials not thoroughly studied. We investigated uranium on some characterized TiO2 surfaces with particular attention to influence surface area, charge, impurities. The U(VI) differed significantly between samples. Aggressive pretreatment one material remove impurities altered...
Abstract Brannerite‐based glass‐ceramics have been developed as potential waste forms for the immobilization of actinide‐rich radioactive wastes. For first time, formation brannerite phases in glass has demonstrated using uranium (U) and plutonium (Pu) with additions gadolinium hafnium neutron absorbers. Both XRD SEM ‐ EDS confirm that is dominating phase compositions close to Y 0.5 U Ti 2 O 6 , Gd 0.2 Pu 0.3 0.1 Hf 0.6 internally crystallized glass. TEM SAED Raman spectroscopy reveal...
IONSIV R9120-B is a commercial inorganic ion exchange material used in the nuclear industry for removal of Cs-137 from contaminated liquids. Once loaded with radioactive species, it considered waste and requires treatment by incorporation into stable wasteform to prevent radionuclide release during disposal. This work presents promising, novel candidate glass-ceramic based on pollucite immobilization cesium-loaded IONSIV. The tailored provides chemical processing flexibility through addition...
Abstract Ln 2 Ti O 7 (Ln=Y and Gd) pyrochlore glass‐ceramics have been fabricated successfully via internal crystallization. Subsequently, the phase evolution from pyrochlores to 0.5 U 6 brannerites in glass with uranium (U) substitutions on Ln‐site of has investigated using X‐ray diffraction, scanning electron microscope‐electron dispersive spectroscopy, transmission microscopy, Raman diffuse reflectance spectroscopy. Combined characterization by XRD , SEM ‐ EDS TEM SAED confirms structures...
Four iso-structured uranyl oxide hydrate phases containing heavy lanthanide ions have been synthesized under hydrothermal conditions and characterized.
Environmental contextZinc, an essential micronutrient often applied to crops as a fertiliser, can be difficult analyse in plants due limitations of conventional techniques. Here, we use radiotracers and non-destructive imaging technique visualise how zinc nanofertiliser moves within wheat over time. This is important step towards developing cost-effective fertilisers help solve one the world’s most widespread plant deficiencies. AbstractZinc (Zn) deficiency affects half arable soil one-third...
We have synthesized two uranyl oxide hydrate (UOH) phases incorporating La(III) or Nd(III) ions under hydrothermal conditions. Investigations with scanning electron microscopy and transmission (TEM) revealed thin-plate morphologies a U-to-Ln atomic ratio of 2:1 (Ln = La Nd), while single-crystal X-ray diffraction TEM studies confirmed that both UOH crystallized in the trigonal P31m space group layered structures La(III)/Nd(III) as interlayer species. Vibrational spectroscopic typical...
Two uranyl oxide hydrate frameworks (UOFs) incorporating either Eu(iii) or Gd(iii) ions were synthesized hydrothermally and structurally studied. The hydroxide layers similar to those in β-U3O8 with both tetragonal pentagonal bipyramidal uranium polyhedra are connected pairs of through cation-cation interactions form three-dimensional inside the channels. Both SEM TEM examinations revealed needle crystal morphologies a U:Eu/Gd ratio 5.5, TEM-SAED pattern indexed orthorhombic structure C2221,...
High magnetizations are desirable for spintronic devices that operate by manipulating electronic states using built-in magnetic fields. However, the moment in promising dilute oxide nanocomposites is very low, typically corresponding to only fractions of a Bohr magneton each dopant atom. In this study, we report large magnetization formed ion implantation Co into amorphous TiO2−δ films, producing an inhomogeneous moment, with certain regions over 2.5 μB per Co, depending on local...
