B4C–TiB2 composite ceramics, with their unique integrated design of structure and function, have demonstrated remarkable potential in extreme environments, such as ultrahard wear-resistant applications and high-temperature electromagnetic shielding. However, the inherent brittleness of ceramics presents substantial machining challenges for fabricating complex geometries, significantly restricting their practical implementation. The development of robust joining technologies thus represents a critical pathway toward manufacturing large-scale and intricately shaped B4C–TiB2 architectures. To date, no studies have been reported on joining B4C–TiB2 composites, making this a vital yet unexplored research frontier. Addressing this gap holds tremendous potential to broaden their industrial applicability and pioneer novel advancements in advanced ceramic engineering.
Glasses are regarded as promising luminescent materials due to their distinct superiorities of physicochemical stability, cost-effectiveness and convenient preparation. However, developing thermal-stable glass scintillators for multi-scenario applications without compromising luminescent efficiency remains a rigorous challenge. Especially for Cu+-doped glass scintillators, there are very few studies on improving their luminescent efficiency and thermal stability. Therefore, it is necessary to fill this research gap and develop the potential of their multi-functional applications.
Researchers have explored the phenomenon of shape coexistence in nuclei surrounding 172Hg, revealing the interplay between nuclear pairing interactions and complex shape dynamics. The study provides theoretical insights into shape isomers and structural evolution and refines models of nuclear behavior in mid-shell regions.
In recent years, low-dimensional materials have become a hot spot for nonlinear optics research due to their unique electronic structure and optical properties. However, how to achieve more significant nonlinear optical responses in low-dimensional materials and actively modulate their properties remains an important challenge in current research. To this end, researchers have explored various strategies such as electric field modulation, excitation resonance and heterostructure construction to enhance the ultrafast nonlinear optical response of materials.
Polarons, as quasiparticles formed by the strong interaction between carriers and lattice vibrations, can significantly modulate the band gap, carrier mobility, diffusion, composite and other properties of functional materials, which has become a research hot research topic in recent years. Soft lattice lead halide chalcogenides exhibit strong electron-phonon coupling effects due to their unique polarity and dynamic disorder, which provides an ideal environment for the formation of this polarons. Polarons can also achieve the modulation of the optical properties of materials, such as the formation of polarons can promote the efficient upconversion of photons. However, the direct correlation between polaronic states and nonlinear optical response of low-dimensional has not been fully investigated.
