ABSTRACT Silicone rubber (SR) is limited by its inherent flammability and heavy smoke generation. Inspired by natural hierarchical structures (e.g., nacre, bone) where organic–inorganic synergies create exceptional properties, this study developed a bio‐inspired organic–inorganic hybrid flame retardant, gum arabic‐mod…
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…
FINDING: Sumerian/Babylonian base-60 mathematics encodes reciprocal pairs and proportional fractions (igi-n-gál, igi-te-en) with potential geometric significance for transport corridors. | MATH: Base-60 (sexagesimal) system; reciprocal pairs: igi-n-gál = 1/n (e.g., igi-2 = 30, igi-3 = 20, igi-4 = 15, igi-5 = 12, igi-6…
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…
Magnesium alloys are the lightest structural metallic materials (density ρ = 1.3–1.65 g cm⁻³) and possess a range of attractive properties, including good castability, excellent damping capacity, superior electromagnetic shielding performance, favourable biocompatibility, and environmental sustainability. These attrib…
Abstract This study investigates the enhancement of the antimicrobial activity of α-Ag2–2xMxWO4 microcrystals, where Mx represents Cu1.15 and Zn1.16, through femtosecond (fs) and nanosecond (ns) laser irradiation. The research highlights how laser exposure induces significant changes in the structural properties of th…
The influence of chemical water treatment (CWT) sludge in standard elastomer compositions based on polyisoprene rubber SKI-3 and methylstyrene rubber SKMS-30 ARKM-15 was studied. The effect of CWT sludge additives on the rheological and physico-mechanical properties of vulcanizates was investigated in comparison with…

Ein Datensatz mit 55 Textilklassen wurde mit hochaufl¨osender Industriekamera erfasst, zu 256 × 256px-Patches (Laplace-Varianz) vorver…
The study presents the results of investigations concerning the influence of microstructure, in particular the fraction of martensite and bainite, on the abrasive wear resistance of alloy cast steels with microadditions of boron and vanadium. Two cast steels were subjected to various heat treatment routes to obtain di…
This study investigates and discusses the hairiness of woven fabrics produced from cotton waste yarn. The study was divided into three interrelated basic parts. The first part of the study focuses on the hairiness of the cotton waste yarn, the second part of the study discusses the methodology allowing the assessment…
Solid–liquid interfacial heat transfer plays a key role in microelectronic devices, energy systems, and liquid cooling technologies. However, the vibrational mismatch at solid–liquid interfaces produces an interfacial thermal resistance (ITR) that limits the heat-dissipation efficiency. Herein, molecular dynamics (MD)…
Electrochromic devices (ECDs) in smart buildings have been advanced as a potential solution for improving energy savings and visual and thermal comfort. The current paper is a review of advanced control strategies for ECDs with respect to predictive, environmental, and adaptive strategies for improving building perfor…
Abstract Colloidal nanocrystal chemistry is highly developed within a narrow range of binary and simple ternary compositions, with reliable control over size, shape, surface chemistry, and the optical, electronic, and magnetic properties they govern. That control covers a small set of structure types, and the mechanis…
This paper develops a revised mathematical solution framework for the chemistry challenge "Predict side products and impurity profiles before scale-up?". The proposed Mass-Balanced Impurity Branching Network (MIBN) was constructed after an earlier formulation failed or remained only partially supported. The specific f…
FINDING: Golden ratio (φ) appears as a structural principle in photonic crystals and galaxy-scale formations, with a mathematical property of self-similarity across infinite sequences. | MATH: φ = (1+√5)/2 ≈ 1.6180339887; reciprocal φ⁻¹ = φ-1 ≈ 0.618; key identity: φ² = φ+1; infinite sequence property: any sequence de…
Amorphophallus spp., valued as both crops and medicinal plants, are highly susceptible to soft rot disease, causing substantial yield and economic losses during cultivation and storage. Calcium nanoparticle (CaNP) fertilizer not only has the potential to enhance crop yields but also plays a crucial role in the control…
The influence of the hydrophilicity of mesoporous silica on wetting with water was investigated by comparing a standard hydrophilic MCM‐41 and a partially hydrophobicized material obtained by trimethylsilylation of MCM‐41. The materials were characterized using X‐ray diffraction, N 2 physisorption, thermogravimetric a…
Abstract Organic cocrystals have emerged as a cutting-edge strategy for constructing high-performance organic functional materials, with their significance in materials science increasingly prominent. This study successfully constructed a charge transfer (CT) eutectic system using electron-rich clamparene (CLP) as the…
Calotropis gigantea is widely used in traditional medicine, but comparative evidence concerning the antidiabetic and organ-protective effects of its different anatomical parts remains limited. This study evaluated the phytochemical constituents and therapeutic effects of methanolic extracts derived from the leaves, st…
