“…Fe 2p was fitted into six peaks. The peaks at 710.0 and 723.7 eV are assigned to Fe 2+ , and their satellite peak locates at 714.3 eV; the peak at 728.1 eV is ascribed to Fe 3+ , and its satellite peaks locate at 718.8 and 731.5 eV (Figure i). ,, These results indicate that Fe exists in Fe 2+ and Fe 3+ states in titanite.…”

Ferroptosis is an iron-dependent cell death and is associated with cancer therapy. Can it play a role in resistance of postoperative infection of implants, especially with an extracellular supplement of Fe ions in a non-cytotoxic dose? To answer this, "nanoswords" of Fe-doped titanite are fabricated on a Ti implant surface to resist bacterial invasion by a synergistic action of ferroptosis-like bacteria killing, proton disturbance, and physical puncture. The related antibiosis mechanism is explored by atomic force microscopy and genome sequencing. The nanoswords induce an increased local pH value, which not only weakens the proton motive force, reducing adenosine triphosphate synthesis of Staphylococcus aureus, but also decreases the membrane modulus, making the nanoswords distort and even puncture a bacterial membrane easily. Simultaneously, more Fe ions are taken by bacteria due to increased bacterial membrane permeability, resulting in ferroptosis-like death of bacteria, and this is demonstrated by intracellular iron enrichment, lipid peroxidation, and glutathione depletion. Interestingly, a microenvironment constructed by these nanoswords improves osteoblast behavior in vitro and bone regeneration in vivo. Overall, the nanoswords can induce ferroptosis-like bacterial death without cytotoxicity and have great promise in applications with clinical implants for outstanding antibiosis and biointegration performance.

“…Over the past few years, interface engineering has been regarded as one of the effective ways to optimize catalytic activity due to the synergistic advantages of each one-component material. − The coupled heterojunctions possess unique geometric and electronic structures, including the optimized charge transfer property and adsorption energy of catalytic intermediates. − For example, the downshift of the d-band center and electron transfer is realized in a hybrid of NiC 2 O 4 and Nb 2 O 5 , which is further designed as an efficient bifunctional electrocatalyst for HER and HzOR . Meanwhile, the carbon layer-encapsulated Fe-CoNiP is synthesized as an excellent electrode material for HzOR and HER in alkaline seawater . The interfacial structure not only optimizes the electrical behavior of the heterostructure but also promotes the kinetic process of the catalytic reaction.…”

Hydrazine oxidation assisting water splitting is considered as a promising strategy toward the highly efficient and energy-saving hydrogen acquirement. However, the development of efficient and stable electrocatalysts for hydrazine hydrate oxidation (HzOR) as well as hydrogen evolution reaction (HER) still remains challenging. In this study, an interface-coupled Co(OH)2/MoS2 nanosheet array is designed to form a synergistic hierarchical heterostructure on a carbon cloth substrate, which is shown to have superior bifunctional performance for HzOR/HER under alkaline conditions. Benefiting from the abundant electrocatalytic active sites and improved reaction kinetics, the Co(OH)2/MoS2/CC electrode shows superior bifunctional performances with low potentials of −134 and 177 mV at 100 mA cm–2 for HER and HzOR, respectively. For the hydrazine-assisted overall water electrolyzer system (OHzS), the Co(OH)2/MoS2/CC electrode delivers low potentials of 142, 197, and 271 mV to realize 10, 50, and 100 mA cm–2, which proves the promising potential application in large-scale preparation of hydrogen fuel. This strategy put forward a simple way toward robust and economic electrodes for energy-related systems.
