Insights Into High‐Temperature Mechanical Properties and Oxidation Behavior of Ta‐Optimized TiAl‐Based Alloys Additively Manufactured via Directed Energy Deposition

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Directed energy deposition (DED) is an effective method to process complex components with high efficiency, owing to its significant advantage of material saving and features of microarea metallurgy and rapid solidification. This study presents a nano‐Ta‐optimized Ti‐45Al‐8Nb (at%)‐based alloy synthesized via DED. The prepared TiAl‐based alloy

A Comparison of the Gut Microbiome of Two Sympatric Macropods Along an Urbanisation Gradient in Tasmania

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Our study is the first to explore how macropod gut flora vary across levels of urbanisation, exploring the faecal microbiomes of the red‐bellied pademelon (Thylogale billardierii) and the red‐necked wallaby (Notamacropus rufogriseus rufogriseus). There is some evidence of urbanisation's impacts on the macropod microbiome, although there appear to be ...

Atomic Layer Deposition in Transistors and Monolithic 3D Integration

Advanced Functional Materials, Volume 36, Issue 41, 21 May 2026.
Transistors are fundamental building blocks of modern electronics. This review summarizes recent progress in atomic layer deposition (ALD) for the synthesis of two‐dimensional (2D) metal oxides and transition‐metal dichalcogenides (TMDCs), with particular emphasis on their enabling role in monolithic three‐dimensional (M3D) integration for next ...

Tantalum carbide and nitride diffusion barriers for Cu metallisation [PDF]

Microelectronic Engineering, 2002
The reactions in the Si/TaC/Cu and Si/Ta2N/Cu metallisation systems were investigated by X-ray diffraction, Rutherford backscattering, scanning electron microscope and the transmission electron microscopy. The results were then combined with the assessed ternary Si–Ta–C, Ta–C–Cu, Si–Ta–N and Ta–N–Cu phase diagrams.

Consolidation of B4C-TaB2 eutectic composites by spark plasma sintering

Journal of Asian Ceramic Societies, 2015
The in situ synthesis/consolidation of B4C-TaB2 eutectic composites by spark plasma sintering (SPS) is reported. The microstructure–property relations were determined for composites with the B4C-TaB2 eutectic composition as functions of TaB2 content, and

Local Structure and Vacancy Distribution in Transition Metal Carbides: Results From High‐Resolution 13C NMR Spectroscopy

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
The local carbon environment in the refractory transition metal carbides ZrC, HfC, NbC, and TaC was studied using high‐resolution magic angle spinning 13C NMR spectroscopy. Results show that carbon nuclei with next nearest neighbor vacant sites or oxygen/nitrogen impurities are distinguishable through 13C NMR, and that the technique can be used to ...
