A simple one-step photopolymerization strategy is presented to fabricate multifunctional shape-memory polymer composites capable of remote and programmable light-triggered actuation. The composites integrate gold nanoparticles and semicrystalline poly(ethylene)-block-poly(ethylene oxide) nanoribbons within a cross-lin…
Lanthanide-doped Ca2Nb2O7 offers versatile and tunable luminescence properties. Previous studies have shown that Pr3+-doped and Pr3+/Er3+ co-doped Ca2Nb2O7 ceramics exhibit non-destructive mechanoluminescence, up- and down-conversion luminescence, and thermoluminescence, with potential for optical temperature sensing.…
Conventional honeycomb-based radar-absorbing structures (RAS) typically employ uniform material properties, which severely restrict broadband absorption when structural load-bearing capability is simultaneously required. To address this limitation, this study designed and optimized a multifunctional, gradient honeycom…
This repository contains a dedicated Python analysis script (Jupyter Notebook / Google Colab format) for automated Scanning Electron Microscopy (SEM) image analysis, dual-phase segmentation, and spatial dispersion mapping of multiphase polymer nanocomposites. The codebase automates the quantitative microstructural cha…
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…
Bacterial strain CS8 T , a novel bacterial cellulose producer, was isolated from a ‘mother of vinegar’ during an artisanal acetification process in Faro, Portugal and characterized. Strain CS8 T stained Gram-negative and formed rod-shaped cells that grew optimally at 30 °C and at pH 5.5–6.5. Phylogenetic analyses base…
Abstract Colloidal semiconductor nanorods (NRs) are promising room-temperature single-photon sources because of their solution processability, tunable optical properties, and intrinsically linearly polarized emission. However, simultaneously achieving high photoluminescence quantum yield (PLQY), strong polarization, a…
Abstract Controlling chemical homogeneity during aqueous coprecipitation of oxide nanoparticles remains challenging due to unintended byproducts that impact the microstructure and functionality of the final materials. Hence, precise tuning of structural, optical, and catalytical properties requires not only accurate k…
This paper introduces a new class of solid state capacitive batteries that store energy in structured electric fields rather than chemical bonds. Building on the General Connectivity (GC) framework and recent advances in resonant nuclear power and coherence based superconductivity, the work addresses the next major bo…
Abstract Pristine two-dimensional (2D) binary materials such as CB, CN, and BN possess wide electronic band gaps and weak optical responses outside the ultraviolet (UV) region, which severely limit their effectiveness in multispectral nanodevices. To address this limitation, we present a quantitative density functiona…
ABSTRACT Multivalent‐ion‐based electrochromic devices have attracted considerable attention for their excellent coloration efficiency and optical modulation. However, they remain limited by slow switching speeds and insufficient cycling stability due to the strong interactions between multivalent ions and host materia…
Abstract The capture of volatile radioiodine from nuclear fuel reprocessing off-gas streams remains a critical challenge due to the high volatility, long half-life, and biological uptake of 129I from the environment. Although silver-based sorbents provide strong iodine chemisorption, their high cost and regulatory cla…
This revised article addresses Q0196, 'How can we validate AI-based spectral interpretation so that inferred structures remain chemically auditable?' using a question-specific mathematical construction rather than a generic logarithmic template. The proposed model, termed the Auditable Spectral-Structure Posterior Mod…
Achnatherum splendens was used as a high-lignin herbaceous feedstock to compare the effects of dilute sulfuric acid and sodium hydroxide pretreatments on component degradation and cell wall structure. Chemical composition analysis, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning e…
Calotropis gigantea is widely used in traditional medicine for treating various health conditions. This study evaluated the phytochemical composition and comparative therapeutic effects of methanolic extracts from its leaves, stem bark, and roots in streptozotocin (STZ)-induced diabetic albino rats. Plant materials we…
Nannoconus , an extinct calcareous nannoplankton genus, characterized by a heavy calcite skeleton (micaliths; ~200-1400 picogram), was a major planktonic producer in the Early Cretaceous seas (~150-120 Ma) contributed to massive marine carbonate accumulations for over ~30 million years. However, the calcification site…
**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…
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…
Magnesium (Mg) is known for its biocompatibility in degradable body implants, with mechanical properties similar to bone tissue. Pure Mg corrodes too fast for implants, but alloying or coating are methods to slow down the implant surface degradation. Using density functional theory calculations we study the adsorption…
Electromagnetic interference (EMI) shielding is essential in modern electronics, telecommunications, and aerospace systems. Graphite-based materials are promising shielding candidates due to their tunable electrical conductivity, low density, corrosion resistance, and thermal stability. However, numerical studies inve…
