To better understand the heterogeneous anisotropic nanocomposite features and provide reliable underlying constitutive parameters of carbon fiber for continuum-level simulations, hierarchical modeling approaches combining quantum chemistry, molecular dynamics, numerical analytical micromechanics are employed studying structure-performance relationships precursor-inherited sheath-core layers. A robust debonding force field is derived from energy matching protocols, including bond dissociation enthalpy calculations rigid-constraint potential surface scan. Logistic long range stretching curves with exponential shifted vdW designed to diminish perturbations. The pseudo-crystalline microstructure proposed validated using virtual wide angle X-ray diffraction patterns bond-orientational order parameters. distribution or alignment microstructures collected chemical topology analysis normal vector extractions. Non-equilibrium tensile loading simulation predicts decomposed strain contributions, principal-axis modulus, strength limit, localized stress, fracture morphologies model. Finally, an atomistically-informed stiffness prediction model homogenization self-consistent Eshelby-Mori-Tanaka-type effective mean theory proposed, giving a successful estimation overall matrix system. models in combination carbonization reaction template will help providing efficient feasible schemes synergistic process-performance control distinct types fiber.

This study investigates the crystal structure, physicochemical properties, and pharmacokinetic profile of Ethyl 2-amino-6-methyl-4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxylate (EAMT) as a potential therapeutic agent. The structure was analyzed using Hirshfeld surface analysis in conjunction with quantum theory atoms molecules (QT-AIM). Non-covalent interactions were evaluated through reduced-density gradient reduction, revealing that EAMT is stabilized by hydrogen bonds between water molecules. molecular electrostatic nature examined MESP, while global local descriptors calculated to assess compound’s reactivity. Molecular docking Adenosine A1 receptor performed validated 50 ns dynamics simulation (MDS). Results suggest influences protein potentially stabilizing specific secondary elements. compactness showed slightly more compact conformation marginally increased solvent exposure presence ligand, indicated Rg SASA values. total binding free energy (ΔG total) determined be −114.56 kcal/mol. ADMET predictions demonstrated EAMT’s compliance Lipinski’s Pfizer’s rule five, indicating good oral availability. compound may exhibit low-potency endocrine activity. In conclusion, presents candidate, warranting further exploration its interactions, pharmacokinetics, safety concerns.

The development of ambient-air-processable organic–inorganic halide perovskite solar cells (OIHPSCs) is a challenge necessary for the transfer laboratory-scale technology to large-scale and low-cost manufacturing such devices. Different approaches like additives, antisolvents, composition engineering, different deposition techniques have been employed improve morphology films. Additives that can form Lewis acid–base adducts are known minimize extrinsic impacts trigger defects in ambient air. In this work, we used 3-thiophenemalonic acid (3-TMA) additive, which possesses thiol carboxyl functional groups, convert PbI2, PbCl2, CH3NH3I CH3NH3PbI3 completely. This strategy effective regulating kinetics crystallization improving crystallinity light-absorbing layer under high relative humidity (RH) conditions (30–50%). As result, 3-TMA additive increases yield power conversion efficiency (PCE) from 14.9 16.5% its stability maximum point. Finally, found results work highly relevant provide additional inputs ongoing research progress related engineering as one efficient strategies reduce parasitic recombination enhance inverted OIHPSCs environment processing.
