Two uranium oxide hydrate frameworks (UOHFs) with either Dy
Although uranium oxide hydrate (UOH) minerals and synthetic phases have been extensively studied, the role of ammonium ions in formation UOH materials is not well understood. In this work, stabilization a phase with inclusion nitrate were investigated using range structural spectroscopic techniques. Compound (NH
We report the synthesis of two new dual-cation uranium oxide hydrate (UOH) materials, containing both Cd2+ and K+ ions, along with their characterisation by means single-crystal X-ray diffraction a range other structural spectroscopic techniques. The materials were found to differ in structures, topology cation ratios, layered UOH-Cd crystallising plate morphology U : Cd K ratio 3 1.5 1. Conversely, framework-type UOF-Cd incorporates much less Cd, 4.4 0.2 1 is as needle-like crystals. A...
A thermally promoted postsynthetic rearrangement has been performed on a zinc IRMOF-9-type framework bearing dimethylthiocarbamate tag groups. The was accomplished via conventional heating at 285 °C. Crucially, despite the high temperature, MOF maintains its accessible surface area and pore space following thermal treatment. structures physical properties of frameworks were characterized by combination single-crystal X-ray diffraction, powder differential thermal-thermogravimetric analysis,...
Two new mixed-valence uranium oxide hydrate frameworks (UOFs), incorporating either Er3+ or Y3+ ions, were successfully synthesised under hydrothermal conditions and characterised with single-crystal X-ray diffraction a variety of other structural spectroscopic techniques. Both are isostructural crystallise in the triclinic P1̄ space group, consisting β-U3O8 type layers pillared by additional uranyl centres, Er3+/Y3+ ions lying channels framework. SEM-EDS analysis found that both materials...
Two synthetic uranium oxide hydrates with Ba( ii ) ions, a 2D layered structure and complex 3D structure, were synthesised hydrothermally characterised.
A uranium oxide hydrate framework with Sr( ii ) ions was synthesized hydrothermally and characterized.
The synthesis of two zinc-bearing uranium oxide hydrate (UOH) materials has been achieved, and their crystal structures, obtained via single-crystal X-ray diffraction using synchrotron radiation, additional structural spectroscopic properties are reported herein. Although both structures incorporate Zn2+ cations, the differ significantly. compound Zn2(OH)2(H2O)5[(UO2)10UO14(H2O)3] (UOHF-Zn), forming a framework-type structure in P1̅ space group, was composed β-U3O8 layers pillared by uranyl...
Direct radiative heating at 200 °C quantitatively converts sulfoxide-tags to desirable vinyl groups on a porous zinc(<sc>ii</sc>) metal–organic framework analogue of IRMOF-9.
Bulk glasses exhibit extra vibrational modes at low energies, known as the boson peak. The microscopic dynamics in nanoscale alumina impact performance of qubits and other superconducting devices, however existence peak these has not been previously measured. Here we report neutron spectroscopy on Al/Al$_2$O$_{3-x}$ nanoparticles consisting spherical metallic cores from 20 to 1000 nm surrounded by a 3.5 thick glass. An intense low-energy is observed $\omega_{BP}$ = 2.8 $\pm$ 0.6 meV for...
Herein, we report coupling in situ high temperature postsynthetic modifications (PSMs) metal-organic frameworks (MOFs). Thermo-reactive propargyloxy-functionalized zinc IRMOFs (isoreticular frameworks) prepared from 2-(prop-2-yn-1-yloxy)-[1,1'-biphenyl]-4,4'-dicarboxylic acid (H2bpdcOCH2CCH) were investigated for their high-temperature rearrangement (PSR) chemistry to heterocyclic chromenes and benzofurans then coupled solid-gas reactions with molecular oxygen. The selectivity the initial...
