Effects of SO2 on the long-term corrosion behaviour of K452 superalloy

open access: yesnpj Materials Degradation
The corrosion behaviour of a nickel-based superalloy K452 in a simulated gas turbine blade service environment (Air+2 vol.% SO2) at 900 °C up to 2000 h was investigated by both microstructural characterization and the Molecular Dynamics (MD) calculations.

Ab Initio Study on 3D Anisotropic Ferroelectric Switching Mechanism and Coercive Field in HfO2 and ZrO2

open access: yesAdvanced Functional Materials, EarlyView.
This study uncovers a new switching mechanism in HfO2 and ZrO2, where the absence of a non‐polar layer along the a‐direction induces interaction between polar layers. Consequently, the switching barriers for growth are lower than those for nucleation in this direction, leading to a size‐dependent coercive field that matches experimental observations ...

Effects of Al element addition on the microstructure and mechanical properties of Mg–Li–Sn alloy

open access: yesJournal of Materials Research and Technology
High strength and low-alloy Mg-1.8Li–2Sn–1Al (TLA221) and Mg-1.8Li–2Sn–2Al (TLA222) alloys were prepared, and the strengthening mechanism of TLA222 alloys was studied. TLA221 and TLA222 alloys were prepared by casting and extruded at a temperature of 523

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

open access: yesAdvanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

Study on the microstructure and properties of TiB2-CoCrFeNiW0.2 metal ceramic composites prepared by pressureless sintering

open access: yesJournal of Materials Research and Technology
Three types of TiB2-HEA ceramic composite were prepared using a non-equimolar ratio CoCrFeNiW0.2 high entropy alloy (HEA) as a binder, mechanical alloying (MA), and 1600 °C pressureless sintering (PS) processes.

NanoMOF‐Based Multilevel Anti‐Counterfeiting by a Combination of Visible and Invisible Photoluminescence and Conductivity

open access: yesAdvanced Functional Materials, EarlyView.
This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.

Over 10 K elastocaloric effect in ω-phase-free TiZrNbSn alloy

open access: yesMaterials Research Letters
Ti-based shape memory alloys are promising for elastocaloric cooling but typically fail to meet the practical 10 K adiabatic temperature change (ΔTad) threshold.

From Low Symmetry to High Dissymmetry: Chiral Plasmonic Films of Binary and Nanobipyramid Assemblies

open access: yesAdvanced Functional Materials, EarlyView.
This work develops highly dissymmetric chiral plasmonic thin films by helically assembling gold nano bipyramids within a liquid‐crystal template. Engineering of the chiroptical response is achieved by varying particle size and geometry, as well as preparing binary assemblies.
