Abstract Surface passivation of Ni‐based electrocatalysts during the electrocatalytic urea oxidization reaction (UOR) renders them impractical and inefficient for applications requiring high current densities. Herein, an efficient strategy to suppress Ni(OH) x nanosheets is demonstrated by modulating near‐surface properties using plasma immersion ion implantation, more importantly, formation threshold UOR‐active γ‐NiOOH phase retained. As a result, remarkable UOR density up 470 mA cm −2...
Abstract The rational design of electronic and vacancy structures is crucial to regulating enhancing electrocatalytic water splitting. However, creating novel vacancies precisely controlling the number in existing materials systems pose significant challenges. Herein, a approach optimize concentration CN (V ) NiFe Prussian blue analog (PBA) nanocubes designed by incorporating H 2 or O plasma treatment. relationship between V catalysis analyzed, results show that moderate (6.5%) can...
Abstract In bone implants, antibacterial biomaterials with nonleaching surfaces are superior to ones based on abrupt release because systemic side effects arising from the latter can be avoided. this work, a concept is demonstrated by fabricating 2D nanoflakes in situ magnesium (Mg). Different conventional mechanisms that depend Mg 2+ and pH increase, exert mechanical tension onto bacteria membranes destroy microorganisms contact produce intracellular stress via physical interactions, which...
The power generated by flexible wearable devices (FWDs) is normally insufficient to eradicate bacteria, and many conventional antibacterial strategies are also not suitable for applications because of the strict mechanical electrical requirements. Here, polypyrrole (PPy), a conductive polymer with high mass density, used form nanostructured surface on FWDs purposes. films PPy nanorods (PNRs) found sterilize 98.2 ± 1.6% Staphylococcus aureus 99.6 0.2% Escherichia coli upon mild...
MoSe2 is an efficient catalyst for the hydrogen evolution reaction (HER) and can potentially replace conventional catalysts composed of noble metals such as Pt. The HER activity originates mainly from edge sites Se atoms, but low concentration exposed to electrolyte hampers performance. Hence, activating a larger portion basal plane atoms effective way improve properties. Herein, 3D hierarchic nanoflower structure comprising with atomic-scale interlayered graphene layers in nanosheets...
Plasma functionalization can increase the efficiency of MoSe2 in hydrogen evolution reaction (HER) by providing multiple species but interactions between plasma and catalyst are not well understood. In this work, effects ion energy density on catalytic properties nanosheets studied. The through-holes resulting from etching multi-vacancies induced plasma-induced damage enhance HER as exemplified a small overpotential 148 mV at 10 mA cm-2 Tafel slope 51.6 dec-1 after treatment using power 20...
Owing to the desirable degradation rate and good biocompatibility, zinc (Zn) Zn alloys are promising biodegradable implant metals in orthopedic cardiovascular applications. Surface modification, such as deposition of coatings, is frequently implemented further enhance their biological properties. In this study, diamond-like carbon (DLC) films deposited on by magnetron sputtering. The DLC do not change surface morphology but alter hydrophobic properties with a contact angle approximately 90°....
Inexpensive and efficient catalysts are crucial to industrial adoption of the electrochemical hydrogen evolution reaction (HER) produce hydrogen. Although two-dimensional (2D) MoS
Bacteria killing behavior based on physical effects is preferred for biomedical implants because of the negligible associated side effects. However, our current understanding antibacterial activity nanostructures remains limited and, in practice, nanoarchitectures that are created orthopedics should also promote osteogenesis simultaneously. In this study, tilted and vertical nanolamellar structures fabricated semi-crystalline polyether-ether-ketone (PEEK) via argon plasma treatment with or...
