- Abstract:
- ... RhCo alloy nanotubes were synthesized via the reduction of single-phase Co₂RhO₄ nanotubes. The reduction was conducted by thermal annealing of the Co₂RhO₄ nanotubes under hydrogen gas flow. The crystallinity of the prepared RhCo alloy nanotubes depended on the reduction temperature: amorphous phase (200 °C reduction) and the crystalline phase (300 °C reduction). The hydrogen evolution reaction (HE ...

Tungsten, a non-Li-intercalating material, was used as a platform to study solid–electrolyte interface/interphase (SEI) formation in lithium hexafluorphosphate in mixed diethyl carbonate (DEC)/ethylene carbonate electrolyte solutions using in situ neutron reflectometry (NR). A NR measurement determines the neutron scattering length density (SLD)-depth profile, from which a composition-depth profil ...

- Abstract:
- ... Transient electronics have dramatically changed inner-body therapy in health care. They stand out because of their harmless dissolution in the human body with no lingering electronic trash. However, high-precision biomedical implants require programmable and serial remedy operations, and controlling the whole-device destruction is not proactive and precise. Thus, a novel biotriggered and temperatu ...

- Abstract:

The release process was activated by interfacial pH increase originating from H⁺ consumption during O₂ reduction bio-electrocatalyzed by bilirubin oxidase immobilized at the electrode surface. The pH increase resulted in a change of the electrical charge from positive to negative at ...
