Summary: By using ceramic templates derived from bulk block copolymer self-assembly, a versatile method for synthesizing mesostructured metals is demonstrated, showing emergent quantum-scale phenomena. High-pressure infiltration of bulk block copolymer self-assembly based ceramic templates enables the study of high-quality metals with previously inaccessible architectures, paving the way for block-copolymer derived quantum metamaterials.

Summary: The mechanical behavior of disordered graphene networks (DGNs) was studied, revealing prolonged plastic platforms in tension and shear, and special plastic damages in compression, resulting in tension-compression asymmetry. Additionally, out-of-plane topological defects and average angular defects in deformed DGNs exhibit inverse proportional scaling relationship. Ashby charts demonstrate that the mechanical properties of DGNs can surpass those of most conventional materials, reaching theoretical limits.

Summary: PCHs, consisting of PCs and stimuli-responsive hydrogels, act as a sensing system for specific analytes by undergoing volume phase transitions upon exposure to external stimuli. The VPT of the hydrogel causes changes in the photonic stopband of the PCs, leading to shifts in Bragg diffraction peak wavelengths. This sensing mechanism allows for the development of various PCH sensors capable of detecting external stimuli.

The researchers used magnetically tunable photonic crystals to achieve Chern vectors and their topological surface states. The experimental results demonstrate that Chern vectors are intrinsic bulk topological invariants in three-dimensional topological materials.

Summary: This study describes the manufacturing of a solid-oxide fuel cell anode with micro-scale continuous linear pores and nano-scale interparticle pore structures, achieved through sacrificial templating method. The highly regular pores are expected to enhance mass transport of hydrogen gas at the active sites, leading to increased energy efficiency of the fuel cell. Simulation results show that an optimal pore size can maximize mass transport acceleration while minimizing concentration overpotential.

Summary: We propose a laser-speckle imaging technique called Echo speckle imaging (ESI) that can quantify the local dynamics in biological tissue and soft materials. With a noise level around or below 10% of the measured signal, the spatial resolution is not affected. This is achieved through unconventional speckle beam illumination, creating changing and statistically independent illumination conditions, significantly improving measurement accuracy. Control experiments on dynamically homogeneous and heterogeneous soft materials and tissue phantoms demonstrate the effectiveness of the method.

Summary: Recent studies have reported the existence of photonic bandgaps (PBGs) in disordered hyperuniform network structures with high enough refractive index contrast. However, the current experimental methods are unable to achieve the smallest central gap wavelength close to the near-infrared light spectrum. In this study, the authors demonstrate a heat-treatment induced shrinkage of the network's polymer template obtained by direct laser writing (DLW), allowing for smaller feature sizes and a pronounced gap near telecom wavelengths.

Summary: This study proposes a framework for describing light transmission through three-dimensional amorphous dielectric materials that exhibit both localization and a photonic bandgap. By considering the density of states of photons and coherent reflection, the authors are able to quantitatively describe light transmission in different transport regimes. Numerical simulations support their theoretical approach.
