Summary: Nanocrystalline metallic materials exhibit better mechanical properties, corrosion resistance, and biocompatibility compared to their coarse-grained counterparts. This review summarizes the mechanical properties, corrosion behavior, biocompatibility, and clinical applications of different types of nanocrystalline metallic materials. The special nanostructures of nanocrystalline materials, such as Ti and Ti alloys, shape memory alloys, stainless steels, and biodegradable Fe and Mg alloys prepared by high-pressure torsion, equiangular extrusion techniques, contribute to their superior properties. The review also provides guidance and references for future research on nanocrystalline metallic materials for biomedical applications.

Summary: By combining machine learning capabilities and in-situ transmission electron microscopy measurements, a new deformation sequence of dislocation gliding and pinning, a quiescent period, and sudden release of localized strain in aluminum-carbon nanotube composites has been revealed. A plastic deformation mechanism with three essential characteristics has been proposed, and the implications for plasticity carriers in crystalline media and amorphous solids have been discussed.

Summary: In this study, the electronic properties of individual single-wall carbon nanotubes were controlled by altering the local chirality using in situ transmission electron microscopy. A transition towards a larger chiral angle region was observed, leading to a controlled metal-to-semiconductor transition. Additionally, quantum transport at room temperature was demonstrated for the fabricated nanotube transistors with a channel length as short as 2.8 nanometers.

Summary: Three different graphene foam (GF) were synthesized using ethylene glycol (EG), sodium hypophosphite, and l-ascorbic acid (L-AA) as reductants via a simple hydrothermal method. The choice of reductants significantly affected the micro morphology and microwave absorption (MA) performance of GF, with EG displaying the best MA efficiency. At a filling amount of 2 wt% and a matching thickness of 3.38 mm, the GF with EG as the reducing agent achieved a minimum reflection loss (RLmin) of -55.89 dB, accompanied by an effective absorption bandwidth (EAB) of 6.88 GHz.

Summary: The designed AB intermetallic compound type high-entropy metallic glass precursor shows high thermal stability and polymorphic crystallization behavior, leading to the formation of nanocrystalline single-phase high-entropy alloy. The nucleation and growth rates for crystallization strongly depend on the annealing temperature. This discovery provides an effective way to develop nanocrystalline single-phase high-entropy alloys by designing intermetallic compound type high-entropy metallic glass precursors.

Summary: Bismuth-telluride (Bi2Te3)-based thermoelectric modules require an optimal metallization layer to achieve high efficiency operation at medium temperatures. This study proposes a novel Fe-Ni-Cr layer to overcome the performance limitations of the widely used Ni layer. The Fe-Ni-Cr metallization demonstrated better performance and reliability compared to Ni metallization.

Summary: This paper investigates high permittivity nanocomposites by modifying 2D conductive MOF Ni-3(HHTP)(2) onto MXene nanosheets for fabricating high permittivity poly(vinylidene fluoride) (PVDF) nanocomposites with low dielectric loss. The results confirm the successful grafting of Ni-3(HHTP)(2) MOF on MXene nanosheets. The MOF-MXene/PVDF nanocomposite exhibits a high permittivity of 530 with a dielectric loss of 0.49 at 4.76 wt% under 1 kHz.

Summary: Novel Fe86-xP11C2B1Inx (x = 0, 0.2, 0.4, 0.6, 0.8 and 1) amorphous alloys were developed in this study. After appropriate annealing, Fe85.8P11C2B1In0.2 nanocrystalline alloy with low coercivity (2.9-21.0 A/m) and high saturation magnetization (1.63-1.73 T) was obtained. The nanocrystalline structure was confirmed by XRD and TEM, and In microalloying was found to induce nanocrystallization in FePCB amorphous alloy according to Kissinger's plot. This provides a new approach for developing Fe-based nanocrystalline soft magnetic alloys.
