Summary: This research utilizes photographic slides as two-dimensional diffraction gratings to study and demonstrate the fundamental properties of dodecagonal quasicrystals. It complements our previous studies on decagonal and octagonal quasicrystals by constructing and presenting corresponding diffraction gratings.

Summary: The concrete realization of topological quantum computing using low-dimensional quasiparticles, known as anyons, remains an important challenge. This study proposes quasicrystal materials as a natural platform for topological quantum computing and shows their anyonic behavior. The correspondence between different-dimensional quasicrystals and the fusion Hilbert spaces of the Fibonacci anyons is studied, and a concrete encoding method for topological quantum information processing on quasicrystals is presented.

Summary: Although aviation is considered safe, the number of pilots blinded by laser light is a significant problem. Limited research has been conducted on the intensity of laser light of different wavelengths passing through the aircraft and standard glasses used by pilots. Understanding the effects of laser glare on pilots can help reduce accidents and improve safety procedures.

Summary: In this study, femtosecond laser ablation was used to generate nanoparticles from decagonal quasicrystals in a liquid medium. The structural analysis showed that the nanoparticles retained the phase of the target material. Formation of Al3Ni2 phase was observed in Al70Co20Ni10, while no formation of Al-Ni phase was observed in Al70Co15Cu10Ni5. Optical analysis confirmed the formation of Al2O3 in both cases, with a weak signal of CuO detected in Al70Co15Cu10Ni5. Laser-induced periodic surface structures were also studied in the ablated region of the target's surface.

Summary: This study presents an innovative concept of subwavelength-featured graphene supercapacitor arrays fabricated by induction-inhibition femtosecond laser scribing. The supercapacitors exhibit outstanding performances and significantly higher capacitance values compared to capacitors. Additionally, they also demonstrate considerable cycling stability and high stability to mechanical cycling.

Summary: This research introduces a unified method for meshing surfaces with unconventional tile patterns, both periodic and aperiodic. The method is applicable to various cases of directional symmetries that have been little studied, including odd and high N. The meshes designed using this method can be used in architectural, industrial, and recreational design.

Summary: This paper analyzes the possibility of using quasi-periodic structures as diffraction gratings. Quasi-periodic structures with eight axes of symmetry were successfully generated and fabricated on a diamond substrate using Ammann-Beenker tiling. The impact of increasing the number of symmetry axes on the generated structures was also examined. The proposed solution holds promise for realizing structures designed to diffract light.

Summary: A new concept of higher-order Airy patterns is proposed in this paper, which introduces the orbital angular momentum of light for customizing OAM beams. By using higher-order Airy patterns to define the performance metric of combined beams, the fiber laser array system is optimally designed, achieving energy concentration and high mode purity of generated OAM beams.

Summary: In this work, a photopatterning method based on UV-laser irradiation is presented to create periodic structures of biomacromolecules by inducing local and mild denaturation of protein biolayers. The resulting nanostructures exhibit a periodic modulation of protein activity, making them suitable for application in diffractive biosensing. The study shows that this UV-based patterning principle is an easy, cost-effective, and fast way to fabricate large areas of homogeneous one-dimensional protein patterns, and these patterns can effectively be used as transducers for biosensing applications.

Summary: This article investigates the diffraction measures for S-adic tilings in R-d, constructed from a family of geometric substitution rules. It gives a sufficient condition for the absence of the absolutely continuous diffraction spectrum for most of S-adic tilings from a family of binary block substitutions, proving it for 'almost all' cases.

Summary: The use of laser light pointers for feline play is popular and enjoyable, but may lead to the development of compulsive behaviors in cats. Significant associations were found between the frequency of laser light play and the occurrence of all surveyed ARBs, especially behaviors connected to laser light play. Outdoor access and cat age were also significant predictors of reported ARBs.

Summary: Phonon-polaritonic crystals (PPCs) combine hyperbolic hexagonal boron nitride (hBN) and silicon-based photonic crystals, and are investigated using near-field excitation and scattering-type scanning near-field optical microscopy (s-SNOM). The study reveals repetitive local field distribution patterns resembling Archimedean-like tiling on hBN-based PPCs.
