ABSTRACT Bio‐based adhesives are gaining traction by virtue of their tremendous potential for substituting petrochemical adhesives, yet the restricted adhesion performance, poor water retention, and intrinsic flammability severely hindered their scale‐up application. Herein, drew inspiration from gecko setae and biomi…
FINDING: Discovery of quasicrystals with forbidden five-fold rotational symmetry, enabled by Penrose tiling and the golden ratio, disproving the classical crystallographic restriction theorem. MATH: - Crystallographic restriction theorem: periodic lattices in 2D/3D allow only 1-, 2-, 3-, 4-, 6-fold rotational symmetri…
Extracting governing mathematical laws directly from raw empirical datasets is a fundamental challenge in scientific computing and artificial intelligence. Classical symbolic regression methods suffer from combinatorial search spaces, while pure deep learning approaches lack mathematical interpretability. In this pape…
Abstract Hydrogen-like systems in ultra-high magnetic fields are of significant interest in interdisciplinary research. Previous studies have focused on the exciton wavefunction shrinkage under magnetic fields down to artificial crystal lattices, while further compression toward the natural crystal lattice remains exp…
Polyamide 66 reinforced with 25 wt.% short glass fibres (PA66-GF25) is widely used in engineering applications requiring long-term operation under combined thermal and lubricated conditions, including polymer bearing cage applications. However, the long-term evolution of its mechanical behaviour under thermo-oil expos…
This perspective proposes a structural accessibility hypothesis for interpreting negative biodegradation results in crosslinked photopolymer additive-manufacturing materials. The hypothesis is deliberately non-exclusive: an observed low biodegradation fraction may reflect intrinsic chemical recalcitrance, limited acce…
Abstract Covalent organic frameworks (COFs) are highly ordered, porous organic materials whose reticular construction from tailored nodes and linkers enables atomic-level control over structure and function. The design space of COFs is vast with virtually unlimited combinations of nodes, linkers, and functional groups…
This paper develops a revised mathematical solution framework for the chemistry challenge "Discover room-temperature, ambient-pressure superconductors with reproducible evidence?". The proposed Conjunctive Superconductivity Evidence Gate (CSEG) was constructed after an earlier formulation failed or remained only parti…
Analysis code, derived data and manuscript source for a study of spatial order in Cahn–Hilliard coarsening. In a phase-separating system with a locally conserved order parameter, the concentration field is hyperuniform, with Sc(k) ~ k⁴, while the point pattern of domain centroids is not: S(k→0) settles on a plateau ne…
Abstract This study presents a comparative analysis of Si/ZnO/HfO2 heterostructures formed by annealing metallic Zn deposited beneath HfO2 in oxygen and nitrogen atmospheres. It investigates oxidation behavior, structural transformations, defect dynamics, and the fabrication of a photodetector based on the grown mater…

FINDING: Five-fold rotational symmetry is forbidden in periodic lattices but emerges in quasicrystals via aperiodic tiling governed by the golden ratio. MATH: Golden ratio φ = (1+√5)/2 ≈ 1.618; its reciprocal φ⁻¹ ≈ 0.618; complex golden ratio ζ = e^(iπ/5) = φ/2 + i√(3-φ)/2 (a 5th root of unity). Penrose tilings use tw…
FINDING: Penrose tiling is a 2D aperiodic projection from a 5D hypercubic lattice, using the golden ratio φ to define the projection subspace. MATH: - Projection from 5D cubic lattice ℤ⁵ onto a 2D plane. - The subspace is spanned by vectors (1, φ, φ², φ³, φ⁴) and its Galois conjugate (1, φ⁻¹, φ⁻², φ⁻³, φ⁻⁴), where φ =…
Abstract Herein, for the first time, an azophenine-based organic functional material, N1,N2,N4-tris(2-methoxyphenyl)benzene-1,2,4,5-tetraamine (MMCT), was rationally synthesized by the solvent-free tetramerization of o-anisidine using low Lewis-acid catalyst loading. SC-XRD, HR-MS, UV–vis, fluorescence, FT-IR, and 1H…
Nitrogen and sulfur co-doped carbon quantum dots (NS-CQDs) were synthesized from rice straw using two sustainable bottom-up approaches, microwave-assisted carbonization (MCW) and hydrothermal treatment (HTC), to systematically investigate how the synthesis route influences their physicochemical properties and biologic…
This paper develops a revised mathematical solution framework for the chemistry challenge "Create foundation models that generalize across molecules, reactions, spectra, and materials?". The proposed Adapter-Based Chemical Foundation Architecture (ACFA) was constructed after an earlier formulation failed or remained o…
Abstract We describe the evolution of our early hit-identification workflow for reagent-mediated amidation reactions in support of commercial route development. Over the past decade, our strategy progressed from broad, exhaustive high-throughput experimentation (HTE) with limited data maturity to a modern, enterprise-…
Plastic production and consumption have increased substantially due to the favorable properties of these materials, raising significant environmental concerns because most plastics do not fully decompose. A substantial portion of ocean plastic waste comes from ghost gear, including abandoned fishing nets. In this cont…
Abstract Steam coating forms protective boehmite films on aluminum alloys; however, identifying the primary factors governing corrosion resistance remains challenging due to strong descriptor covariance. We established a physics-informed interpretable machine-learning framework to predict pitting potential ( E pit ) f…
