A new class of extractants called hexaalkylphosphoramides has been chosen for actinide separation applications in the present study. Hexaalkylphosphoramides [(NR2)3PO] are compounds which possess three nitrogen sub-units along with a strong donor oxygen atom. The studies on them provide an oppor...

A novel pillararene–indicator system between anionic water-soluble pillar[6]arene (WP6) and an aromatic fluorescent dye acridine orange (AO) was constructed. Upon complexation with electron-rich cavity of WP6, AO showed a fluorescence quenching and color change due to the host–guest charge-tra...

The seasonal stability of solar-induced chlorophyll fluorescence (SIF) vs field-measured leaf CO2 assimilation (A) was assessed over a period of 2 years by means of airborne flights performed at midday and diurnally over a citrus (evergreen) crop canopy. The orchard was cultivated under a contro...

Recently, developing free rare-earth (RE) doped afterglow phosphors has received great attentions in the lighting field. In this work, we prepare and report a RE-free phosphor, Na2BeGeO4:Mn2+, which can simultaneously emit the green fluorescence and afterglow luminescence upon excitation at UV l...

Terrestrial humic-like substances (Peak C), the main constituent of chromophoric dissolved organic matter (CDOM), which is one of the optically active constituents present in water, is a good indicator of the ecological statuses of global aquatic ecosystems. In this study, the optical relationsh...

Tracking the variation of the algogenic organic matter (AOM) released during the proliferation of green algae and subsequent treatment processes is crucial for constructing and optimizing control strategies. In this study, the potential of the spectroscopic tool was fully explored as a surrogate...

We determined the potential interference of extracellular algal organic matter (EAOM) and intracellular algal organic matter (IAOM) extracted from Microcystis aeruginosa on MS2 bacteriophage inactivation under UV irradiation at two wavelengths (220 and 254 nm). UV irradiation at 220 nm doubled t...

The temperature dependence of the lattice parameters of Cs2MoO4 was measured using the high-temperature X-ray diffraction method, from room tem

The vaporization behavior of cesium molybdate (Cs2MoO4) has been studied by using the Knudsen effusion mass spectrometry. A combination of a molybdenum outer cell and an alumina inner Knudsen cell was utilized in the Nuclide 12–90 HT high temperature mass spectrometer. The obtained vapor pressu...

A phase separation technique was applied to a simulated high-level vitrified waste, which consisted of nonradioactive elements, to determine the efficient extraction of cesium from the vitrified material. Experimentally, the simulated vitrified material was melted at 900–1000 °C and subsequent...

The reprocessing of irradiated nuclear fuel at Sellafield produces a nitric acid based Highly Active Liquor (HAL) waste. The liquor, containing fission products and process additives, is concentrated in an evaporator in order to reduce the volume and is then stored in Highly Active Storage Tanks...

The vaporisation behavior of caesium molybdate has been investigated in the liquid region (1230 to 1310 K) by a transpiration technique using dry oxygen as the carrier gas. Chemical and X-ray diffraction analysis of the condensate as well as the residue confirmed the vaporisation to be congruent...

Molybdenum, cesium and selenium along with potassium-rich materials were phase-separated onto the surface from the borosilicate glass containing simulated high level radioactive wastes by heat treatment under a CO2-containing atmosphere. The phase separation behaviors of potassium, molybdenum, c...

Keggin-type heteropoly molybdates with different cesium and vanadium contents were synthesized and characterized by X-ray diffraction, FT-infrared, in situ Laser Raman, X-ray photo electron spectroscopy and temperature programmed desorption of NH3 techniques.
