تحلیل بنیادین، بازنویسی تانسوری و اثبات جامعِ کامل پارادوکس فوقکشسانی اتمی و فروریزش مدلهای شکست مکانیکی در نانوالیاف پلیمری تحت تأثیر نوسانات خلأ (The Quantum-Induced Hyper-Elasticity Paradox and Mechanical Collapse in Polymer Nanofibers - معمای شماره ۷۱ از ۱۰۰) در بستر فیزیک اطلاعات حمزه (HIP-1155) به شرح زیر است:…
**FINDING:** Icosahedral symmetry group \( I_h \) (order 120) is simple, and its rotational subgroup \( A_5 \) is the smallest non-abelian simple group. The group is intimately linked to the golden ratio \(\phi\) and appears in optimal volume-to-surface ratio problems (e.g., icosahedron is the Platonic solid with maxi…
Cathodic protection (CP) is used in the marine industry to prevent corrosion of metal components in seawater but may also promote biofilm formation. When steel and copper alloy components are in contact, the latter is often subjected to higher applied CP voltages than otherwise required when a steel component is not p…
We present TP-Agent, an autonomous LLM-based agent utilizing a Plan–Execute–Reflect architecture and external computational tools (Python, Mathematica) to assist in theoretical physics research. We evaluate it on two benchmarks: the comprehensive TPBench and the frontier-level PRL-Bench. While TP-Agent demonstrates st…
Abstract The development of crystalline proton-conducting materials with well-defined structures is crucial for exploring the proton transport mechanism and advancing proton exchange membrane fuel cells. Polyoxometalates (POMs), specifically the {P2Mo5} and {P4Mo6} clusters, have emerged as promising building blocks o…
Hexagonal boron nitride (h-BN) is a lubricant additive with considerable application potential. Its layered structure provides low interlayer shear strength, while its favorable thermal stability, chemical inertness, and electrical insulation make it attractive for demanding lubrication environments. However, the trib…
This revised article addresses Q0028, 'Understand dynamic wetting and contact-line motion on complex surfaces?' using a question-specific mathematical construction rather than a generic logarithmic template. The proposed model, termed the Dynamic Contact-Line Depinning Model, uses contact-line velocity U, capillary nu…
Maqolada yelka suyagi proksimal qismi sinishlarida medial tayanch va CALCAR sohasi barqarorligini tiklashning jarrohlik natijalariga ta’siri tahlil qilindi. Medial ustunning buzilishi, metafizar komminutsiya va CALCAR defekti bloklovchi plastina bilan osteosintezda ikkilamchi varus deformatsiya, vintlarning bo‘g‘im ic…
FINDING: The five Platonic solids are the only convex regular polyhedra, arising from constraints on vertex figures and face angles, with molecular geometry reflecting their symmetry groups. MATH: Euler's formula: V - E + F = 2. For regular polyhedra: {p,q} where p = sides per face, q = faces per vertex. Constraint: 1…
This revised article addresses Q0041, 'Benchmark AI chemistry on prospective experiments rather than retrospective datasets?' using a question-specific mathematical construction rather than a generic logarithmic template. The proposed model, termed the Prospective Chemistry Generalization Model, uses retrospective sco…
Abstract Superhard materials typically rely on strong localized covalent bonds, which suppress electronic delocalization and thus hinder metallicity or superconductivity. Here, we propose a strategy to overcome this limitation by introducing Zn atoms into a hexagonal diamond framework. We predict a metastable ZnC10 co…
This study investigated an eco-friendly route for producing silver nanoparticles (AgNPs) and immobilising them on cellulose recovered from coconut coir, an agricultural residue. Cellulose was extracted from Cocos nucifera coir through alkali treatment, acid treatment and bleaching. Juice obtained from Anacardium occid…
Abstract The rapid growth of the Indonesian automotive sector, marked by over 147 million four-wheeled vehicles and rising annual sales, has intensified the demand for disposable oil filters. Current filters are primarily made of synthetic fibers, glass fibers, and paper or porous synthetic foam, creating non-recyclab…
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…
