Abstract Several unsymmetric photoswitchable benzo[b]phosphole-fused diarylethenes have been synthesized. Compared with their symmetric counterparts, the photochromic properties of the unsymmetric benzo[b]phosphole-fused diarylethenes, including photocycloreversion efficiency, fatigue resistance, and thermal irreversi…
FINDING: Discovery of quasicrystals with forbidden five-fold rotational symmetry, breaking periodic lattice dogma, linked to Penrose tiling and golden ratio. | MATH: Golden ratio φ = (1+√5)/2 ≈ 1.618; its reciprocal 1/φ ≈ 0.618; φ² = φ+1 ≈ 2.618; φ⁻² = 2-φ ≈ 0.382. Five-fold symmetry is incompatible with periodic Brav…
This is the instrument paper of the Structural Control series, and it is deliberately two-sided, with every claim carrying a declared evidence stratum. The telemetry side is measured: a single-channel precursor estimator — rolling median, robust MAD threshold, persistence gate — as two predeclared, cadence-scaled conf…
Abstract Developing organic−inorganic hybrid nanomaterials generating multiple optical signals remains challenging due to inherent design complexities. Herein, we present organic-SiO2 nanohybrids exhibiting size-dependent room-temperature phosphorescence (RTP) and structural color. By employing a covalent anchoring st…
El presente trabajo documenta una extensión empírica al marco teórico del Toroide Cuántico Numérico en módulo 12 (Z/12Z). A partir del análisis visual de la matriz armónica, revelamos la existencia de un patrón palindrómico estricto que gobierna la distribución de números primos y compuestos. Al aplicar una involución…
В статье представлено комплексное научное обоснование применения полимерных композиционных материалов (ПКМ) в качестве конструкционной основы силовых элементов (панелей пола) гибридных автомобилей. Установлено, что традиционные металлические сплавы — сталь и алюминий — исчерпали свой потенциал по критерию «масса — жес…
Abstract Understanding the dynamic evolution of heterogeneous catalysts under harsh conditions is critical for controlling active site activation and deactivation. In this work, we investigate the hydrothermal evolution and reaction-driven dynamics of Pd confined within CHA zeolite. The confinement effect of the CHA f…
The series identifies every Standard-Model interaction vertex with a Reidemeister move on knotted brane loops, and the path integral with a sum over Reidemeister sequences (Papers VIII, XII); the standing open item is the measure. This paper establishes the geometric half of a candidate answer and is explicit that the…
The development of future energy conversion devices passes inevitably through the improvement of the mass transport and oxygen exchange of the oxygen electrode. Herein, we show how nanoporosity can be used to enhance reducibility and thereby oxygen evolution in LaMnO 3 and how it influences the electronic transport in…
FINDING: Quasicrystal diffraction indexed via golden ratio basis vectors and higher-dimensional projection methods; golden ratio emerges as a stable local recurrence operator in self-application systems. MATH: - Golden ratio φ = (1+√5)/2 ≈ 1.618, reciprocal 1/φ = φ−1 ≈ 0.618, φ² = φ+1 ≈ 2.618, φ⁻² = 2−φ ≈ 0.382. - Bas…
The solution phase synthesis of metal nanocrystals proceeds via physicochemical processes that have yet to be fully elucidated. Variable temperature liquid phase transmission electron microscopy (VT-LPTEM) has emerged as an important technique to enhance our knowledge of nanoparticle formation mechanisms. However, the…
Abstract High-energy ball milling (HEBM) is increasingly used to modify complex biopolymeric materials; however, quantitative energy-based descriptions of structural transitions in insect flours remain limited. This study investigated the energy-dependent structural and thermal evolution of grasshopper ( Sphenarium pu…
A series of five novel Schiff bases (SBs) was synthesized via condensation of substituted aryl aldehydes with sulfachloropyridazine (SCPZ) and fully characterized by UV-Vis, FTIR, 1H/13C NMR, and CHNS elemental analyses. Experimental vibrational frequencies showed good agreement with density functional theory (DFT) ca…
This paper develops a revised mathematical solution framework for the chemistry challenge "What reaction networks govern unwanted crosslinking and char formation during plastic upcycling?". The proposed Branching Polyolefin Deconstruction Network (BPDN) was constructed after an earlier formulation failed or remained o…
Recently, the development of hybrid composites has witnessed remarkable growth because they exhibit many applications, including environmental and medical applications [ 1 , 2 ]. Organic–organic (e.g., chitosan (CS)–starch, CS-protein, and CS-alginate), organic–inorganic (e.g., starch–TiO 2 , alginate–TiO 2 , and chit…
This thesis contains works on polypeptide hydrogels for tissue engineering. Although synthetic, their derivation from amino acids grants biocompatibiltiy with increased mechanical performance when compared to natural alternatives. The synthesis of the polypeptides was altered to faciley change the method of 3D printin…
Abstract Magnetic refrigeration provides a potentially more energy efficient alternative to conventional vapor compression systems. The rotating magnetocaloric effect (RMCE), which consists of the rotation of a magnetocaloric material in a constant external magnetic field, enables simpler and more compact magnetic ref…
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…
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 Multiferroics combining ferroelectricity and ferromagnetism within a single phase are promising materials for magnetoelectric (ME) functionalities. Compared with oxide-based systems, molecular materials offer greater structural tunability for realizing coupled ferroic behavior. Here we report a low-symmetry c…
