Microstructural, Magnetic, and Tribological Optimization of Nano‐ZrO2 Reinforced Magnesium Matrix Composites Fabricated via Powder Metallurgy

Engineering Reports, Volume 8, Issue 6, June 2026.
Magnesium–ZrO2 nanocomposites fabricated via powder metallurgy exhibited enhanced density, magnetic saturation (up to 14 emu/g), and wear resistance. Uniform nanoparticle dispersion improved bonding and reduced delamination, demonstrating strong potential for lightweight, multifunctional applications in aerospace and automotive engineering.

Progressively Fenitised Schist and Carbonatitic Clasts From a Metasomatic Aureole Beneath the Alkalic Dunedin Volcano, Otago, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Clasts of albite‐porphyroblastic quartzofeldspathic schist, derived from the Otago Schist basement, occur within the Port Chalmers Breccia, a diatreme at the centre of the Dunedin stratovolcano, New Zealand. Schists have undergone varying degrees of replacement reactions (at temperatures of 300° to >500°C) producing hornfelses, with Ca‐ and K‐enriched ...

Co‐Doped (Na+, Mg2+, Zn2+, Fe3+)‐Carbonated Hydroxyapatites and Composites with MIIFe2O4: Synthesis, Mechanic, Magnetic, and Antibacterial Properties for Medical Application

ChemistryOpen, Volume 15, Issue 6, June 2026.
Multi‐doped (Na+, Mg2+, Zn2+, CO32‐) hydroxyapatite/ferrite composites were synthesized via a one‐stage method. These “smart” materials exhibit high microhardness (3.28 GPa), potent antimicrobial activity, and membrane‐stabilizing effects, reducing erythrocyte hemolysis by up to 25%.

Tuning Y‐Mg Supports for Improved Ni‐Catalyzed NH3 Decomposition: Structural Modulation and Mechanistic Insights

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Catalytic NH3 decomposition has garnered substantial attention for hydrogen transformation and storage. Ni‐based catalysts continue to suffer from limited thermal stability and suboptimal low‐temperature activity, largely attributed to an incomplete understanding of the structure‐activity relationships and reaction mechanisms governing their ...

Tailoring Ni‐MOFs by Microwave‐Assisted Synthesis for Efficient CO2 Methanation

ChemistrySelect, Volume 11, Issue 22, 11 June 2026.
Metal–organic frameworks (MOFs) containing Ni are efficient precursors for CO2 hydrogenation due to their tunable structures. Ni‐MOFs were synthesized solvothermally using 2‐methylimidazole with different synthesis times. The catalyst obtained after 60 min showed higher CO2 conversion, producing CO and CH4, whereas the material synthesized for 30 min ...

Atomic Step–Terrace Ordering Enables Unprecedentedly Low Pop‐in Stress Scatter in GaN (0001)

Small, Volume 22, Issue 34, 17 June 2026.
Step–terrace GaN surfaces with monoatomic topography were realized using catalyst‐referred etching. On these surfaces, pop‐ins occurred at ideal strength with a record‐low stress scatter of 2.3%, providing compelling evidence that atomic‐scale surface ordering plays a critical role in triggering incipient plasticity. Atomic‐scale surface irregularities,

Atomic‐ and Molecular‐Scale Interphase Engineering for High‐Performance Solid‐State Batteries

Small Structures, Volume 7, Issue 6, June 2026.
In this perspective, we summarize the issues of solid‐state batteries (SSBs) and the promising applications of atomic and molecular layer deposition (ALD and MLD) for interphase engineering of SSBs to achieve high performance. Furthermore, we provided our insights on future practices of ALD and MLD for interphase engineering of SSBs.
