Performance and UV‐Induced Microplastics Formation in a PBS/PBAT Blend With and Without Joncryl Reactive Compatibilization

Macromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
This paper aims to examine the biodegradable PBS/PBAT blend with and without the addition of a reactive compatibilizer. The aim of this study is to assess the role of the compatibilizer in the generation of microplastics (MPs) from the biodegradable PBS/PBAT blend after UV‐induced ageing and to provide useful insights for their potential application ...

The investigation of the carbon on irradiation hardening and defect clustering in RPV model alloy using ion irradiation and OKMC simulation

Nuclear Engineering and Technology
The precipitation of solutes is a major cause of irradiation hardening and embrittlement limiting the service life of reactor pressure vessel (RPV) steels. Impurities play a significant role in the formation of precipitation in RPV materials.

Effect of Accelerated Aging on the Performances of 3D Printed Polylactic Acid‐Polyhydroxyalkanoate Specimens

Polymer Engineering &Science, Volume 66, Issue 8, Page 6137-6149, August 2026.
The accelerated aging behaviours on the FFF‐fabricated PLA‐PHA Specimens. ABSTRACT Despite the increasing use of biodegradable polymers in additive manufacturing, their long‐term durability remains insufficiently understood. The aim of this study to investigate the influence of accelerated aging on the performance of fused filament fabrication‐printed ...

Abnormal Phase Transition Mechanism in the CoCrAlY Bond Coat Revealed by In Situ and Ex Situ Experiments

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT In Co‐based alloys, the γ phase is normally stable at high temperatures and the ε phase at low temperatures, and there is a martensitic transition on cooling to ∼417°C. In the γ/β dual‐phase CoCrAlY bond coat of turbine blade thermal barrier coating systems, we observed the opposite: γ remained stable at room temperature, yet it underwent a γ →

Synergistic Enhancement of Strength and Creep Resistance in Additive Manufacturing Ti‐6.5Al‐2Zr‐Mo‐V Alloy via In Situ Co‐Modification With Si and Y Elements

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT The demand for advanced aerospace components necessitates near‐α titanium alloys with enhanced high‐temperature performance and compatibility with additive manufacturing (AM). To address this, an in situ alloying strategy was employed to co‐modify a Ti‐6.5Al‐2Zr‐Mo‐V alloy with Si and Y during laser powder bed fusion.

Achieving High Strength in Metastable β‐Ti Alloys via ω‐Reinforced Heterostructures With Ultrafine Hierarchical Nano‐Martensites

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Precipitation of isothermal ω phase is an effective way to strengthen the metastable β‐Ti alloys but generally severely embrittles the materials by suppressing stress‐induced martensitic transformation and deformation twinning. Here, we architect heterogeneous structures with tailored ω phase in a metastable β‐Ti‐20Zr‐12Nb‐2Sn alloy via ...

Template‐Assisted 3D‐PVDF Nanonetworks for Passive Daytime Radiative Cooling

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
Three‐dimensional polyvinylidene fluoride (3D‐PVDF) nanostructures were fabricated by infiltrating the polymer into 3D anodic aluminum oxide (3D‐AAO) templates. Due to their high solar reflectance (82.4%) and infrared emissivity (96.7% between 8 and 13 µm), they are an ideal candidate for radiative cooling.
