Radium Speciation in Simulated Digestive Biofluids: Insights from Electrospray Ionization Mass Spectrometry and Thermodynamic Modeling

Analysis &Sensing, EarlyView.
Electrospray ionization mass spectrometry (ESI‐MS) combined with thermodynamic modeling provides the first direct characterization of radium speciation in synthetic gastrointestinal biofluids. Free Ra2+ ions predominate with minimal protein binding and negligible EDTA complexation. Crown ethers enable effective Ra complexation.

Innovative Approach to Hydrogen Purification: A Review on the Role of Metal Hydrides

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Metal hydrides, renowned for their unique hydrogen bonding capabilities, have emerged as pivotal materials in the energy sector, particularly for hydrogen storage and purification applications. Their ability to store hydrogen reversibly under moderate conditions has positioned them at the forefront in hydrogen‐based energy systems. This review

Quantum degenerate mixtures of strontium and rubidium atoms

, 2013
We report on the realization of quantum degenerate gas mixtures of the alkaline-earth element strontium with the alkali element rubidium. A key ingredient of our scheme is sympathetic cooling of Rb by Sr atoms that are continuously laser cooled on a ...

Mass scaling and non-adiabatic effects in photoassociation spectroscopy of ultracold strontium atoms [PDF]

, 2014
We report photoassociation spectroscopy of ultracold $^{86}$Sr atoms near the intercombination line and provide theoretical models to describe the obtained bound state energies. We show that using only the molecular states correlating with the $^1S_0$$+$$

First‐Principles Investigation of the Thermoelectric Behavior of the Orthorhombic Cadmium Stannate (Cd2SnO4)

Advanced Physics Research, EarlyView.
Cd2SnO4 exhibits excellent thermoelectric properties with a high Seebeck coefficient, power factor, and figure of merit, surpassing Bi2Te3. It shows both positive and negative Seebeck coefficient values, making it suitable for diverse applications. Its high electrical conductivity and low thermal conductivity enhance efficiency, while its negative Hall

Spectroscopy of $^{87}\text{Sr}$ triplet Rydberg states

, 2018
A combined experimental and theoretical spectroscopic study of high-$n$, ${30 \lesssim n \lesssim 100}$, triplet $\text{S}$ and $\text{D}$ Rydberg states in $^{87}\text{Sr}$ is presented. $^{87}\text{Sr}$ has a large nuclear spin, ${I=9/2}$, and at high-$

Ecology of common bully (Gobiomorphus cotidianus) in the Tarawera and Rangitaiki rivers: isolation by inland distance or anthropogenic discharge? [PDF]

, 2009
Previous research has identified distinct genetic, life-history and reproductive differences between populations of common bully (Gobiomorphus cotidianus) upstream and downstream of a pulp and paper mill outfall on the Tarawera River in the Bay of Plenty,

Geographic Variation of Strontium and Hydrogen Isotopes in Avian Tissue: Implications for Tracking Migration and Dispersal

PLoS ONE, 2009
Background Isotopes can provide unique solutions to fundamental problems related to the ecology and evolution of migration and dispersal because prior movements of individuals can theoretically be tracked from tissues collected from a single capture ...

Photocatalytic Degradation of PFOA with Porous Lanthanoid Perovskites Nano Catalyst

Chemie Ingenieur Technik, EarlyView.
Photocatalytic degradation of PFOA was studied using nickel‐ and lanthanide‐doped perovskites under UV–VIS irradiation. Catalyst characterization confirmed successful doping, with Ni/NdMnO3 showing the highest photocatalytic efficiency. Degradation occurred via C–C bond cleavage, forming transformation products PFHpA and PFHxA.
