Summary: This study investigates the phenomenon of elastic yielding in polymer glasses after cold drawing and annealing. Molecular dynamics simulation reveals that the emergence of elastic yielding requires particles with mobility and structural ordering at the bond level. A theoretical model is proposed to explain the relationship between elastic yielding stress and bond orientation parameter and dissipated energy.

Summary: Understanding the microstructure change of polymer nanocomposites under elongation deformation is crucial for establishing structure-property relationships. In this study, a new in situ extensional rheology NMR device was developed to obtain both macroscopic and microscopic information. A quantitative method was established to analyze the interfacial layer fraction and polymer matrix orientation distribution. The results showed that the interfacial layer has a minor influence on mechanical property change, while rubber network strand reorientation plays a major role. This study contributes to the understanding of the reinforcement mechanism in polymer nanocomposites.

Summary: In this study, the deformation mechanism of amorphous polymeric materials was investigated using ultrasmall-angle X-ray scattering. A stretch-induced phase separation behavior was observed in plasticized poly(vinyl butyral) (PVB) for the first time. The phase separation is influenced by stress concentration and the network structure, and the phase size increases with strain.

Summary: Using the newly developed high count rate positron annihilation lifetime spectroscopy (PALS) facility, in situ PALS experiments were performed for the first time on the continuous stretching process of polymers to analyze the minute-scale evolution of free-volume holes. The tensile process was divided into four distinct stages based on the stress-strain relationship and PALS results, showing the enlargement of free-volume hole size and increasing anisotropy of free-volume holes. This work demonstrates the feasibility of disclosing the minute-scale evolution of material microstructure through in situ PALS experiments.

Summary: The complicated chemical structure and acetalization mechanism of poly(vinyl butyral) (PVB) were revealed using multidimensional NMR with 13C labeling. Isotope enrichment helped determine the sequence distribution of vinyl butyral (VB) and vinyl alcohol (VA) monomers in the PVB backbone, while NMR experiments identified primary, secondary, and tertiary carbons. Various 2D-NMR experiments established coupling through chemical bond or space correlation. The resolved information from 1H and 13C NMR spectra provided insights into the acetalization reaction mechanism.

Summary: The addition of small molecular plasticizer is an efficient strategy to improve the process ability and macroscopic performance of poly(vinyl alcohol) (PVA). This study investigates the influence of plasticizer on chain dynamics and morphology using PVA film with varying glycerol addition levels. The results show that increasing glycerol addition levels decrease the melting temperature and crystallization temperature of PVA, in accordance with Flory's theory. Moreover, the addition of glycerol enhances chain dynamics in the mobile domain and increases the dimensionality of the plasticized PVA film.

Summary: The chain dynamics heterogeneity of poly(vinyl butyral) (PVB) plasticized by triethylene glycol bis(2-ethylhexanoate) (TEG-EH) was investigated using solid-state NMR techniques. The plasticized PVB exhibited two domains with distinct molecular dynamics differences, referred to as rigid and soft domains, where the soft domain contained a higher concentration of plasticizer. The study revealed that the activation energy of components in the soft domain of plasticized PVB were lower compared to the pristine PVB.

Summary: The three-phase structure of poly(vinyl alcohol) (PVA)-iodine complexes was studied using solid-state NMR. The micro-extension of the PVA segment in the interphase and amorphous domains was confirmed, and it was found that the increasing iodine concentration led to an increment in the hydrogen-bonded C(H) fractions in both the amorphous and interphase domains. The results provide evidence for the aggregation model for the formation mechanism of PVA-iodine complexes.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.

Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
