“…Recently, in 2020, Xiao et al have fabricated reduced graphene oxide/tungsten composite (RGO/W) with laminated structure via powder metallurgy method. [114] Owning to the reinforcement effect induced through the nacre-like structure with rGO embedded interfaces, the as-prepared RGO/W composites show much lower hardening rate of 18.6% compared to those of nacre-like W of 129.2% and the commercial W of 40.1%. Recent first-principles calculations indicated that the W/graphene/W interfaces can trap He atoms to retard the diffusion of helium atoms from the interface to the W phase again as well as vacancies to accelerate recombination of vacancies and self-interstitial atoms.…”

Interfaces including grain boundaries and heterophase interfaces could withstand the radiation damage via providing sites for trapping the defects. With the urgent demand for high radiation-tolerance nanostructured materials, exploration of the structural properties, especially the role of the interfaces on the radiation response in the nanomaterials, is of significant essentialness in developing the design of new radiation-resistant materials. Herein, the recent progress and development of two main kinds of interfaces, namely the grain boundaries in nanocrystalline and the hetero-phase interfaces in nanolayered materials and nano-composites, in nanostructured materials that are designed for radiation tolerance are summarized. In addition, the radiation response and resistant mechanism under irradiation conditions of the nanocrystalline materials like metals, single-phase alloys, and ceramics, as well as the nanocomposites like nanolayered metals, nanolayered ceramics, metal-carbon nanocomposite, and nanoparticle dispersed steels, are reviewed. Finally, challenges and perspectives are proposed to offer advice for the development of radiation resistance nanomaterials.

“…The lamellar composite was processed by repeatedly inserting fresh Nb layers during the modified ARB process, and the multilayer was improved in long-term mechanical integrity and resistance to He clusters damage. On the other hand, He et al [94] proposed the W/reduced graphene oxide (RGO) bulk composite material with nacre-like architecture synthesized by spark plasma sintering as shown in Fig. 8c, which exhibited satisfied radiation hardening resistance.…”

Engineering materials for nuclear reactors exposed to high-dose irradiation breed various radiation damage, leading to performance degradation of materials, which seriously limits the application of materials in the future advanced nuclear reactors. Tungsten-based materials applied in future nuclear reactors have to withstand not only the attack of high-energy neutron and plasma, but also the repeated impact of steady-state or even transient thermal load. Researches in the past decades have proved that tailored nanostructure have advantage in annihilating radiation defects. With the rapid development of nanostructured tungsten, probing radiation application of nanostructured tungsten is of great significance in promoting the development of novel radiation-resistant materials. Herein, the development status of three kinds of nanostructured tungsten namely nanocrystalline, nanofilm and nanoporous tungsten designed for radiation tolerance and the performance enhancement mechanism of diverse nanostructure in irradiation environment is reviewed. Finally, future perspectives and technical challenges are discussed, to inspire more creative designs of novel nanostructured tungsten for radiation tolerance.

“…[ 7–9 ] Recent studies suggest that 2D materials not only can endure but can potentially thrive in harsh radiation conditions. [ 10 ] In such conditions, the imminent damage due to long half‐life radionuclides or radioactive decay like gamma radiation (γ‐ray) induced effects is a critical factor to explore. In particular, the gamma radiation effects on graphene [ 11,12 ] carbon nanotubes (CNTs) [ 13,14 ] TMDs [ 15,16 ] and transition metal carbides (MXene) [ 17,18 ] have been studied for potential implementation in various extreme environments.…”

Reliable and highly sensitive flexible physical sensors hold great potential for applications in emerging technologies. Among others, of particular importance is to embed the sensor into operations at the hazardous fields, like radioactive zones or nuclear power plants. However, a significant challenge is to develop the radiation tolerant flexible sensors with stable performance under extreme conditions. This study presents a flexible pressure–temperature sensor based on MXene/Fe3O4/graphene porous network/Ecoflex (MFGPNE) and thoroughly investigates the effect of a high dose of γ‐irradiation on their physical and electrical properties. The proposed sensors are characterized by a 4.71 kPa−1 sensitivity to the applied pressure in the range of 0–62.5 kPa and by a 2.23% resistance change per degree in the temperature range of 21–110 °C. The in situ electrical experiments, performed during irradiation of the MFGPNE sensor by 20 kGy of γ‐rays (60Co), reveal the stable and reliable operation of the sensor. Superior radiation stability and pressure–temperature sensitivity are achieved due to the inherent nature of the materials and the sophisticated design of the proposed sensors. Moreover, an MFGPNE sensor‐based prototype gripper for grasping force control by remote monitoring of the press and lift forces demonstrates the application of the proposed sensor.
