Abstract This work investigates the curing behavior of epoxidised soybean oil (ESO) with citric (CA), maleic (MA), and salicylic (SA) acids. The curing process was monitored by Fourier-transform infrared (FTIR) and dynamic differential scanning calorimetry (DSC) at heating rates of 5–20 °C min–1. FTIR analysis showed…
ABSTRACT Efficient anti‑/de‑icing coatings are urgently needed for outdoor infrastructures in cold climates. Here, we report a photothermal superhydrophobic coating based on ultrasmall‑bandgap tellurium nanowires (TeNWs, E g = 0.43 eV) synthesized via a surfactant‑assisted solid‑solid‑solid growth strategy. The compos…
High-temperature creep resistance is a key requirement for structural materials used in aerospace applications. However, this property remains poorly understood for the EV31 alloy. This study investigates the creep mechanisms of EV31 alloy in temperature range from 200 °C to 300 °C through experimental characterizatio…
Abstract The optical and electronic properties of a two-dimensional (2D) material are profoundly influenced by the nature of its underlying substrate, thereby making the substrate-material interactions a vital factor for both fundamental studies and technological applications. These interactions can significantly modi…
Abstract A series of dialkyl-substituted dicyanoquinodiimine derivatives (Cn-DCNQI; n = 1–7, 12) with systematically varied alkyl chain lengths has been synthesized, and the relationships among crystal structure, intermolecular electronic interactions, and organic field-effect transistor properties have been investiga…
ABSTRACT Photocatalytic oxygen reduction reaction (ORR) is a promising route for sustainable H 2 O 2 synthesis, enabling on‐demand production and in situ water remediation, yet it is still hampered by poor charge separation and migration, as well as sluggish O 2 adsorption and activation. Herein, salen‐based covalent…
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 Chiral recognition is fundamentally pivotal in biomedicine, yet simultaneous discrimination of enantiomers of multiple structurally analogous molecules remains a key challenge. Herein, multicolor achiral carbon dots (CDs) (B-CDs, G-CDs, and Y-CDs) were successfully synthesized and employed for chiral recognit…
ABSTRACT Gold nanoparticles (AuNPs) exhibit size‐ and shape‐dependent physicochemical properties, yet precise morphological control under environmentally benign conditions remains challenging due to the lack of spatial regulation of nucleation and growth. Here, we explore liposome‐based nanoreactors as confined reacti…
FINDING: Project Euler hardest problems often reduce to graph theory (NP-complete clique search) or prime sum sieves with Riemann hypothesis implications. | MATH: Figurate number sequences: heptagonal numbers \( P_7(n) = \frac{n(5n-3)}{2} \); cyclic set condition: last digits of one figurate number match first digits…
ABSTRACT Refractive optics, now over two centuries old and highly mature, remains the cornerstone of optical systems in rapidly growing fields such as robotics and smart sensing, yet has reached its fundamental physical limits. Ultra‐thin metalenses hold transformative potential for next‐generation optics, yet their w…
This research work aims to assess the effect of various materials and production conditions on the impact strength (Izod) of nanographene-reinforced PLA composites. The process variables, comprising extrusion temperature (190, 200, 210, 220, 230, and 240°C), infill pattern (gyroid, honeycomb, and rectilinear), and inf…
Metal oxide nanoparticles synthesized via environmentally benign green routes continue to advance nanotechnology owing to their attractive catalytic and biological properties, and the development of multifunctional nanocomposites based on such materials has recently attracted considerable attention. Nanomaterials capa…
The rapid emergence of extended-spectrum β-lactamase (ESBL)-producing Escherichia coli and Klebsiella pneumoniae has significantly limited the effectiveness of conventional antibiotics, highlighting the urgent need for alternative antimicrobial agents. In the present study, silver nanoparticles (AgNPs) were green synt…
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…
Using plant extracts for the green synthesis of metal oxide nanoparticles offers a sustainable, cost-effective, and environmentally friendly alternative to conventional chemical and physical methods. Copper oxide nanoparticles (CuO NPs) were produced in this study using the aqueous extract of Arachis hypogaea (peanut)…

**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…
