Traversing the Periodic Table through Phase‐Separating Nanoreactors

open access: yesAdvanced Materials, EarlyView.
Centimeter‐scale arrays of single nanoparticles, generated through either Dip Pen Nanolithography or Polymer Pen Lithography, allow for the discovery of novel nanomaterials at an unprecedented scale. The development of phase‐separating hydrophobic nanoreactors bypasses element‐specific chemistry limitations, enabling the synthesis of polyelemental ...

Energy-carbon comprehensive efficiency evaluation of hydrogen metallurgy system considering low-temperature waste heat recovery [PDF]

open access: yesarXiv
To address the lack of energy-carbon efficiency evaluation and the underutilization of low-temperature waste heat in traditional direct reduction iron (DRI) production, this paper proposes a novel zero-carbon hydrogen metallurgy system that integrates the recovery and utilization of low-temperature and high-temperature waste heat, internal energy, and ...

The Role of Post‐Sintering Heat Treatment on the Phase and Microstructural Development of Nano Cu‐Zno Modified Ceramic Surfaces

open access: yesAdvanced Materials Interfaces, EarlyView.
Nano Cu‐ZnO glazes formed multilayered microstructures. Cu doping and concentrations affect phase evolution and microstructure. Post‐sintering heat treatment and its duration are crucial for creating textured microstructures. Abstract The study examines the effect of heat treatment duration on microstructure and phase evolution concerning Cu content in

Atomic Layer Deposition of ZnO Coating on Biodegradable Fe‐Based Alloys

open access: yesAdvanced Materials Interfaces, EarlyView.
A biodegradable Fe69Mn30C1 alloy is coated with ZnO using atomic layer deposition at 100 °C. Coating thickness impacts surface roughness, wettability, and in vitro degradation while maintaining hydrophilicity. The ZnO coating exhibits significant antibacterial activity against Staphylococcus aureus, achieving an inhibitory rate of up to 99.2%, and can ...
