Diffusion of Hydrogen Isotopes in Zirconium Alloys

open access: yesHe huaxue yu fangshe huaxue
Tritium is a common radioactive product in nuclear power plants. It is easy to diffuse, penetrate and be easily absorbed by organisms due to its small atomic radius.

Decoupled and diverse: A morphological examination of the two‐jaw system in Mormyridae (Osteoglossiformes)

open access: yesThe Anatomical Record, EarlyView.
Abstract The tongue‐bite apparatus (TBA) is a secondary jaw system found in Osteoglossomorpha and, convergently, Salmonidae. It is thought to have similar prey‐processing functions as the pharyngeal jaws, possibly allowing the oral jaws to evolve separately for more efficient prey capture.

Carbon‐Embedded Fe‐Cu Composite Oxide Nanoparticles Derived From Spindle‐Shaped Bimetallic MOFs for Selective Oxidation of Methane

open access: yesCarbon and Hydrogen, EarlyView.
Fe3Cu1/C (CuFe5O8) was synthesized by high‐temperature carbonization of FexCuyBDC MOF, which exhibited excellent catalytic performance for methane selective oxidation at 80°C. The synergistic effect between Cu and Fe in the derived Fe3Cu1/C (CuFe5O8) composite oxide inhibits deep oxidation compare to Fe/C (Fe3O4), and the reaction proceeds via a free ...

Scaling Up Molecular Electron Spin Qubits Around a Core‐Shell Quantum Dot

open access: yesChemistry – A European Journal, EarlyView.
Making assemblies of molecular nanomagnet (MNM) qubits is an essential step toward scalable quantum devices. Here, SH‐functionalized {Cr7Ni} antiferromagnetic rings with ability as MNM qubits were successfully grafted to the surface of fluorescent CdSe/ZnS quantum dots (QD).
