Summary: Copolyesters based on FDCA have gained attention due to their superior gas barrier properties and biodegradability. This study assessed the influence of aliphatic diol segmental lengths on the properties of FDCA-based copolyesters. It was found that increasing diol segmental lengths resulted in decreased glass transition temperature and a zig-zag variation in melting temperature. Furthermore, the copolyesters exhibited good mechanical properties, gas barrier properties, and rapid biodegradability.

Summary: A series of biobased short-long chain aliphatic polyesters with high molecular weight were synthesized and systematically studied. The molecular weight of the polyesters showed a linear relationship with the chain length of the diols. The odd-even effect of the diol chain length was observed on the crystallinity and thermomechanical properties of the polyesters. Poly(butylene sebacate) exhibited high crystallinity and storage modulus, indicating good processability and thermal stability.

Summary: The demand for sustainable development has led to increasing attention in biobased polyesters due to their adjustable thermal and mechanical properties and biodegradability. In this study, a list of novel aromatic-aliphatic poly(alkylene adipate-co-thiophenedicarboxylate) (PAATh) copolyesters was synthesized using a novel bioderived aromatic diacid. These copolyesters showed high thermal stability, excellent tensile strength, and superior gas barrier performances. The biodegradability of PAAThs was fully evaluated, and the effect of diol components on enzymatic degradation was revealed by computational analysis. This study provides insights into the development of promising substitutes for commercial biodegradable polyesters and sheds light on their complicated degradation mechanisms.

Summary: This paper synthesized poly(butylene succinate-co-diethylene glycol succinate) (PBSD) copolymers to improve the nonenzymatic hydrolysis of poly(butylene succinate) (PBS). The results showed that the contact angle and water uptake of the copolymer increased significantly, indicating microphase separation occurred. PBSD copolymers exhibited high tensile strength, elongation at break, and decomposition temperature. The weight loss of PBSD copolymers was greater in acidic conditions compared to neutral conditions and simulated seawater. PBSD copolymers have the potential to be utilized as water degradable materials for environmental pollution control.

Summary: In this work, we computed and implemented one-body integrals for Gaussian confinement potentials and established an equivalence between Gaussian and Hooke atoms. We observed that both systems are equivalent for a series of even number of electrons at large confinement depths. Unlike harmonic potentials, Gaussian confinement potentials are dissociative and crucial for modeling phenomena like ionization.

Summary: In this study, a novel family of deep eutectic monomers and corresponding polymers was reported. These polymers were made of (meth)acrylic ammonium salts and biobased polyphenols bearing catechol or pyrogallol motifs. The phenolic chemistry allowed the modulation of ionic polymer properties, resulting in adhesive or tough materials. Furthermore, the phenolic polymeric deep eutectic solvents (polyDES) exhibited metal complexation ability, antibacterial properties, and fast processability by digital light 3D printing.

Summary: Due to environmental concerns with petroleum-derived polymers, the use of natural polymers is increasing. Cellulose and chitin are the most commonly found biopolymers, with chitosan being a promising candidate for nanocarrier development. However, chitosan's solubility in aqueous medium at physiological pH limits its biomedical applicability. In this study, nanogels were successfully synthesized from different chitosan systems using the reverse microemulsion method and a cross-linking agent. The properties of the nanogels were analyzed and their potential use as drug delivery substrates was demonstrated.

Summary: We investigate the dynamics of avalanche ionization in pure helium nanodroplets activated by a weak extreme-ultraviolet (XUV) pulse and driven by an intense near-infrared (NIR) pulse. Short-term activation is caused by the injection of seed electrons into the droplets by XUV photoemission, while long-term activation is due to electrons remaining loosely bound to photoions, forming stable snowball structures in the droplets. These findings demonstrate that XUV irradiation can induce long-lasting changes in the optical properties of nanoparticles, potentially enabling control of avalanche-ionization phenomena in nanostructures and condensed-phase systems.

Summary: Ca- and Mg-based batteries are more sustainable alternatives to Li-ion batteries, but suffer from poor mass transport of cations. Organic positive electrodes, although most sustainable and potentially low-cost, currently have the best electrochemical performances in Ca and Mg cells but suffer from low capacity retention upon cycling, the origin of which is not yet fully understood.

Summary: Organic materials, especially bio-based organic electrode materials (OEMs), have gained attention as sustainable electrode materials for batteries. However, bio-based OEMs for high-voltage batteries are limited. In this study, bio-based polyhydroxyanthraquinones (PHAQs) and their redox polymers were synthesized to address this issue. It was found that PHAQ polymer composites synthesized using formaldehyde as a linker and multiwalled carbon nanotubes (MWCNTs) showed the best cycling performance in lithium metal batteries.
