Wear of Hot-Pressed Aluminum Nitride
Journal of the Ceramic Association, Japan, 1986 窒化アルミニウム焼結体を1700°-2000℃の温度範囲でホットプレス法により作製した. その摩擦摩耗特性をピンオンディスク法で測定し, また摩耗の摺動速度依存性をサバン式試験法により調べた.焼結体の特性としては, ホットプレス温度1700℃では気孔が多く, 破壊靱性, ビッカース硬度はかなり低かった. 1800℃以上ではほぼ一定値に達するが, ホットプレス温度とともに粒子成長が激しくなっている.ピンオンディスク法により測定されたSiCディスクに対する摩擦係数, 比摩耗量はホットプレス温度とともに上昇した.

Advanced Materials Interfaces, EarlyView.This study investigates thermally CVD‐deposited AlN/TiAlN dual‐layer coatings over a Si substrate, focusing on the temperature‐dependent process‐structure relationship. Systematic characterization reveals that a dense AlN interlayer combined with an optimally deposited TiAlN top layer provides enhancement in mechanical strength, tribological stability,

Improved toughness of refractory compounds [PDF]
The concept of grain-boundary-engineering through elimination of the grain-boundary silicate phase in silicon nitride was developed. The process involved removal of the silica from the nitride powder via a thermal treatment coupled with the use of ...

Direct Mode‐Resolved Measurement of Interfacial Phonon Transport by Acoustic Phonon Reflectometry
Advanced Materials Interfaces, EarlyView.We introduce a novel analysis, acoustic phonon reflectometry, that measures the mode‐resolved phonon reflection coefficient at semiconductor interfaces. In aluminum nitride, we observe excellent agreement with the acoustic mismatch model across three distinct interfaces.

Non‐Continuous Iridescent Variable Structural Color Based on Metallic Surface Periodic Structures
Advanced Materials Interfaces, EarlyView.This study presents an ink‐free laser nanofabrication technique that generates periodic arched microstructures on titanium surfaces, achieving non‐continuous iridescent dual‐color switching. The ridge and side flanks of these structures possess distinct oxide film thicknesses, enabling angle‐dependent selective reflection of specific wavelengths.

Advanced Materials Interfaces, EarlyView.Procalcitonin is a key biomarker for bacterial infections, but conventional detection methods are often time‐consuming. Here, we present an electrochemical sensor based on highly conductive Ti3C2Tx MXene combined with PEDOT:PSS, enabling direct antibody immobilization, while a bovine serum albumin coating provides antifouling protection.

Anti‐Slip Material‐Based Strategies and Approaches
Advanced Materials Technologies, EarlyView.This review highlights the principle mechanisms of slipping at the microscale, linking contact mechanics with a friction behavior model for surface interfaces. Main strategies to develop anti‐slip properties to the surfaces are discussed alongside standardized testing approaches.

Advanced Materials Technologies, EarlyView.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...
