Building like a Coral—Parallelized, Multiscale Biofabrication
Advanced Materials, EarlyView.Corals build stiff, strong, and inherently circular skeletal materials under resource‐ and energy‐limited conditions—offering blueprints for transformative materials. We synthesize the current understanding of coral biomineralization and reframe coral growth as a multiscale, parallelized biofabrication process.

The influence of heterogenous porosity on silicon nitride/steel wear in lubricated rolling contact [PDF]
, 2000 Heterogeneous porosity is detected on the surface and subsurface of hot isostatically pressed (HIPed) silicon nitride spherical rolling elements. The extent of the localised porosity accounts for an area of 6% of the rolling element surface and 4% of the

Emergent Freestanding Complex Oxide Membranes for Multifunctional Applications
Advanced Materials, EarlyView.This review surveys freestanding oxide membranes and covers fabrication and three pathways for studies and devices: strain‐free and strained membranes, and van der Waals‐integrated heterostructures. We show how coupled oxide responses map onto these routes and cross‐couple to expand behaviors.

Rolling-element fatigue life of silicon nitride balls: Preliminary test results [PDF]
Hot pressed silicon nitride was evaluated as a rolling element bearing material. The five-ball fatigue tester was used to test 12.7 mm (0.500 in.) diameter balls at a maximum Hertz stress of 800,000 psi at a race temperature of 130 F.

Cr2AlC: A High‐Temperature Transparent Conducting Ceramic
Advanced Materials Interfaces, EarlyView.The high‐quality epitaxial Cr2AlC(0001) layer combines a low resistivity of 42.5 µΩcm, 84% optical transmittance at 900 nm, and thermal stability up to 800–1100°C. It stands out as an excellent high‐temperature transparent conductor with a negligible resistivity size effect, exceptional scaling (ρoλ < 3 × 10−16 Ωm2), and a figure of merit of 0.004 Ω−1.
