Article Abstract
Silk sericin (SS) has been widely discarded as a waste by the silk textile industry during the degumming process to obtain fibroin. However, in the past decade, an in-depth understanding of its properties and functions turned it into a high added-value biomaterial for biomedical applications. Herein, we report the molecular design and development of sustainable supramolecular multilayered nanobiomaterials encompassing SS and oppositely charged chitosan (CHT) through a combination of self-assembly and electrostatically driven layer-by-layer (LbL) assembly technology. The successful buildup of SS/CHT multilayered nanobiomaterials was demonstrated by the quartz crystal microbalance with dissipation monitoring and attenuated total reflectance-Fourier transform infrared spectroscopy, and the nanofilms' wettable properties and nanofibrillar-like topography were shown by water contact angle, atomic force microscopy, and scanning electron microscopy. assays demonstrated the cytocompatibility of the LbL nanofilms toward human primary dermal fibroblasts, holding great promise as biofunctional nanocoatings for drug/therapeutics/cell delivery, tissue engineering, and regenerative medicine.

Water at interfaces plays crucial roles in various natural phenomena and in the material sciences. Therefore, understanding the structure and hydrogen-bonding network at such interfaces is essential. Recent advances in porous crystalline materials, combined with single-crystal X-ray diffraction techniques, have enabled the visualization of molecular structures on pore surfaces at atomic resolution.

Supramolecular polymerization of π-extended compounds with hydrogen-bonding sites remains challenging, especially at high concentrations, due to their limited solubility in nonpolar solvents. Herein, we report a novel method incorporating a thermal precursor approach for the supramolecular polymerization of a poorly soluble tetrabenzoporphyrin (BP) derivative with multiple hydrogen-bonding sites and chiral cholesterol groups (BP). Polymerization in the nonpolar solvent tetralin is induced by the retro-Diels-Alder reaction of the highly soluble precursor (CP) to BP in the hot solution and subsequent natural cooling, as confirmed by monitoring absorption spectra.

Nanoparticle incorporation into supramolecular assemblies is essential for designing hybrid nanostructures with tailored optical and structural properties. However, understanding the interactions that govern the attachment and formation of such composites remains a challenge, particularly when complex structures are involved. In this study, we explore the fabrication of quantum dot (QD)/J-aggregate composites of tetrakis(4-sulfonatophenyl)porphyrin (HTPPS), where electrostatic interactions between cysteamine-functionalized QDs and negatively charged J-aggregates of HTPPS with L-alanine play a key role in their formation.

Post-synthetic modification (PSM) represents a promising approach for enhancing the properties of coordination polymers (CPs) and MOFs by introducing new functional groups and tailored surface chemistry. This study details a tandem PSM of a 2D Zn-coordination polymer (parent compound), [Zn(AIP)(DMSO)]n (Zn-CP), to generate various functionalized structures. In the first step of PSM, Zn-CP-df was created through the removal of coordinated DMSO molecules from [Zn(AIP)(DMSO)]n to form Lewis acid sites.

The stress-strain curve is a key indicator of the mechanical behavior of polymeric materials and plays a vital role in optimizing the performance of solution-polymerized styrene-butadiene rubber (SSBR). Molecular dynamics (MD) simulations enable the investigation of microscale deformation mechanisms, yet their use of unrealistically high strain rates leads to stress values that diverge significantly from experimental results. To address this discrepancy, we proposed a weighted fusion framework that integrates transfer learning with a hybrid long short-term memory-multilayer perceptron (LSTM-MLP) model and the eXtreme Gradient Boosting (XGBoost) algorithm.
