Summary: Multifunctional hydrogel sensors are important for flexible wearable devices, but it is challenging to fabricate sensors with high strength, transparency, UV filterability, environmental stability, self-healing capability, and easy recyclability. This paper successfully prepared a multifunctional composite ionic hydrogel (PGETA) by incorporating tannic acid-coated cellulose nanocrystals (TA@CNC) into a hydrogel. The PGETA hydrogel showed high tensile strength, stretchability, transparency, UV-filtering property, low-temperature tolerance, and moisturizing performance, as well as good self-healing capability and recyclability. It can be used as a wearable device to monitor deformations and physiological signals in different body parts.

Summary: To address the problem of filter wastes, an ecofriendly alternative filter material using plant-sourced biomaterials, namely poly(lactic acid) (PLA) and fungal chitin, was developed. Heterogeneous electrospun fibers with distinctive chitin-rich and PLA-rich regions were formed by inducing phase separation between hydrophilic chitin and hydrophobic PLA polymers. The filtration performance of PLA and chitin-incorporated PLA (ChPLA) webs against NaCl nanoparticles was evaluated, and the study examined the contribution of mechanical and electrostatic particle capture mechanisms, as well as the effect of aging and environmental conditions. The research also demonstrated that ChPLA has higher degradability than PLA in a soil burial test.

Summary: This study investigates the effects of intrinsic and irradiation-induced defects in graphene on the displacement damage and He diffusion in Ni-graphene nanocomposites. The results show that the presence of intrinsic defects significantly affects the Ni lattice structure near the Ni-graphene interface. The irradiation-induced defects, on the other hand, do not decrease the ability of the interface to trap He atoms/clusters and may even improve it.

Summary: Interface plays a significant role in the mechanical properties of graphene reinforced metal composites. Molecular dynamics simulations have been used to study the interfacial characteristics of graphene reinforced iron composite (Gr/Fe) interfaces of different orientations. The results reveal that physical and chemical bonding at the interfaces lead to different interactive energies and bonding lengths. Moire patterns are observed due to the lattice geometrical mismatch between graphene and iron crystal structures. These patterns are influenced by the competition and coordination of binding sites between graphene and Fe atoms.

Summary: This study investigates the effect of grain boundary on the irradiation resistance of CoCrCuFeNi through molecular dynamics simulations. The results show that grain boundaries in both CoCrCuFeNi and Ni can capture point defects, with the number of captured defects depending on the distance between primary knock-on atoms and grain boundary. Tensile stress change in CoCrCuFeNi after irradiation is smaller than that in Ni. Furthermore, the grain boundary of CoCrCuFeNi can annihilate voids at room temperature, while the grain boundary of Ni is hindered in the migration process and cannot completely eliminate voids.

Summary: Short-range order in multi-principal element alloys affects point defect behavior. First-principles calculations were conducted to study the effect of short-range order on vacancy and interstitial formation energy and migration behavior in NbZrTi alloy. Short-range order structures at 500 and 800 K showed higher formation energies for vacancies and interstitials compared to a random solid solution. Point defects preferred migrating towards Zr,Ti-rich regions and away from Nb-rich regions. Short-range order increased the spatial inhomogeneity of point defect energy landscape. Adjusting the degree of short-range order can optimize the point defect behavior in multi-principal element alloys for enhanced radiation resistance.

Summary: The stability of small vacancy clusters in a high-entropy alloy Nb0.75ZrTiV0.5 with body-centered cubic structure was investigated using first-principles calculations and molecular dynamics simulations. The tightly bound configurations were found to have lower structural stability and were not energetically preferred in the studied alloy. The instability of these configurations led to vacancy-atom exchanges that favored less compact configurations. The formation energy of small vacancy clusters was much smaller than that of its constituent elements due to the large structural adjustment induced by severe local lattice distortion. The difference in local lattice distortion and elemental arrangement in the vacancy neighborhood resulted in significant site-to-site variation in vacancy cluster energy and configuration. The unconventional energetics of small vacancy clusters are expected to have a profound impact on their behavior and the defect microstructure evolution during irradiation.

Summary: Recent advancements have led to the synthesis of novel monolayer 2D carbon structures, namely quasi-hexagonal-phase fullerene (qHPC(60)) and quasi-tetragonal-phase fullerene (qTPC(60)). Graphene was chosen as the substrate and encapsulation material. Comprehensive molecular dynamics simulations were conducted to investigate the mechanical stability of 2D fullerene when placed on a graphene substrate and encapsulated within it. The results showed that encapsulation with graphene significantly improved the mechanical reliability of 2D fullerene and defects on the C60 layer had negligible impact on the deterioration of the mechanical properties.

Summary: The effects of topological states on the thermoelectric performance of a Yb-filled CoSb3 skutterudite are studied. The nontrivial topological states are revealed by ab initio calculations and inferred from anomalous Hall conductivity and magnetoresistance. The linear bands associated with the topological states result in low effective mass and high carrier mobility, leading to high power factor. Additionally, filling the voids with Yb atoms raises the valley degeneracy, favoring the Seebeck coefficient and density-of-states effective mass. These effects contribute to the high power factor of the Yb-filled CoSb3 skutterudite. Our results highlight the crucial role of topological states in improving the performance of thermoelectric materials.

Summary: The evolution of short-range order (SRO) structures in NiCoFeCrMn under irradiation was investigated in this study. Molecular dynamics and lattice kinetic Monte Carlo simulations were used to analyze the atomistic mechanism of SRO evolution during and after cascade collisions. It was found that SRO structures could be destroyed in a short time by cascade collisions but could recover through atomic diffusion in a longer time. The destruction rate depended on the primary knock-on atom energies and showed a universal law with respect to the number of replacement-per-atom. Vacancy diffusion simulations revealed that the SRO recovery rates varied significantly for different element pairs due to their distinct diffusion rates. Consequently, the SRO state under irradiation differed from that in thermodynamic equilibrium due to the differences in destruction and recovery rates for each element pair.
