Phase Boundary Engineering of Co2P‐CoP Branched Nanoparticles Enhances Cobalt Oxidation for Oxygen Evolution Electrocatalysis

open access: yesAdvanced Materials, EarlyView.
Phase boundaries between Co2P and CoP are constructed through a controlled transformation of Co to Co2P‐CoP branched nanoparticles. The polycrystalline mixed‐phase Co2P‐CoP branches are enriched with phase boundaries that stabilize Co active sites for OER. This work highlights phase boundary engineering as a powerful approach to tailor active sites and

The Effect of Si and Zr on the Formation of Al3X and V-Phase in a 6005A Alloy with Sc—Part 1: Alloy Design and Heat Treatment Selection

open access: yesJournal of Manufacturing and Materials Processing
Adding Sc to 6xxx series alloys has led to inconsistent results due to the formation of the high-temperature, thermodynamically stable V-phase (AlSc2Si2).

Decoupling Activation and Preservation: Architectural Design Principles of Organic Frameworks for Selective Photocatalytic Methane Oxidation

open access: yesAdvanced Materials, EarlyView.
Selective methane (CH4) photooxidation emerges from architectural decoupling of activation and preservation. Programmable organic semiconductor frameworks spatially organize oxidative flux and intermediate residence, separating reaction zones from product domains to synchronize activation strength with stabilization and establish a selective oxidation ...

Electrical Resistivity Change Upon Crystallization as a Robust Descriptor for Metallic Glass Forming Ability

open access: yesAdvanced Materials, EarlyView.
Electrical resistivity change upon annealing is introduced as a rapid descriptor for identifying high glass‐forming ability in metallic glasses. High‐throughput combinatorial thin‐film libraries reveal that compositions exhibiting small resistivity changes correspond to sluggish crystallization behavior and known bulk metallic glass regions, enabling ...

Thermodynamic Assessment of the Fe–O–Zr, Cr–O–Zr and O–Sn–Zr Ternary Systems

open access: yesCalphad
The Fe-O-Zr, Cr-O-Zr, and O-Sn-Zr ternary systems have been modeled using the CALPHAD (CALculation of PHAse Diagrams) method to develop comprehensive thermodynamic descriptions essential for applications in nuclear materials and corrosion science. Experimental data from the literature and Density Functional Theory (DFT) calculations were used within ...

Far‐Infrared Hyperbolic Phonon–Polaritons in Zirconium Disulfide

open access: yesAdvanced Materials, EarlyView.
An unpatterned ZrS2${\rm ZrS}_2$ flake, coupled to far‐field infrared light by metal nanoribbons, reveals hyperbolic phonon polaritons with multiple higher‐order branches and effective refractive indices up to 223. This resonator‐assisted approach establishes ZrS2${\rm ZrS}_2$ as a compact van der Waals platform for deeply subwavelength far‐infrared ...

Interaction of hydrogen molecules with polycyclic aromatic hydrocarbons modified with Zr atoms: different modifications yield distinct properties

open access: yesResults in Surfaces and Interfaces
Ability of polycyclic aromatic hydrocarbons (PAH), namely coronene (C24H12), circumcoronene (C54H18) and circumpyrene (C42H16) modified with Zr atoms to bind H2 molecules is investigated using density functional theory.

Mechanistically Interpretable Artificial Intelligence for Designing Oxygen Electrocatalysts

open access: yesAdvanced Materials, EarlyView.
Mechanistically interpretable artificial intelligence screens nearly seven million perovskite compositions and identifies key descriptors—d‐p hybridization and densification resistance—that govern oxygen electrocatalysis. The discovered BaCo0.8Nb0.1Zr0.1O3‐δ achieves a record 2.68 W cm−2 peak power density at 600°C with over 500 h of durable operation ...

Water vapor effect on high-temperature oxidation behavior of Fe3Al intermetallics

open access: yesScience and Technology of Advanced Materials, 2009
Fe3Al intermetallics (Fe3Al, Fe3Al-Zr, Fe3Al-Zr,Mo and Fe3Al-Zr,Mo,Nb) were oxidized at 950 °C in dry and humid (11 vol% water) synthetic air. Thermogravimetric measurements showed that the oxidation rates of the tested intermetallics were lower in humid
