Summary: The study investigated the relationship between emulsion stability in shipboard bilgewater and critical micelle concentration in the presence of oil (CMCIFT), finding that CMCIFT was most closely related to emulsion stability. It was observed that emulsions with surfactant concentrations below CMCIFT exhibited oil separation, regardless of homogenization intensities and oil concentrations.

Summary: Establishing the structure-property relationship is crucial for molecular design of copolymers. Machine learning models that consider both chemical composition and sequence distribution of monomers, and have the ability to process different types of copolymers, are needed. In this study, we propose four different machine learning models and find that a recurrent neural network (RNN) architecture that processes monomer sequence information in both forward and backward directions performs better for copolymers.

Summary: The study investigated the thermoresponsive behavior of oil-soluble polymers in non-aqueous solutions and explored the effects of different parameters on their solubility and efficiency. The experiment found that both the hydrophobicity of the polymer chains and the overall order of the system have significant effects on the upper critical solution temperature in oil. Properties of the synthesized polymers were analyzed using methods such as DSC and turbidity measurements.

Summary: Compared to conventional techniques, photoinitiated electron/energy transfer-reversible addition-fragmentation chain transfer (PET-RAFT) allows for better control over the polymerization of multiblock star copolymers, avoiding the generation of termination products. This technique is also tolerant to oxygen, enabling the automated synthesis of multiblock star copolymers at short block lengths, providing a useful approach for screening the effect of polymer composition on solution structure.

Summary: This paper reports the simplified electrochemical atom transfer radical polymerization (seATRP) using Cu-II-N-propyl pyridineimine complexes for the first time. The results show that the polymerization in aqueous solution has good control over molecular weight distribution, and the polymerization process is not completely under electrochemical control. It is proposed that the seATRP using Cu-II(NPPI)2 follows an electrochemically-triggered ATRP mechanism.

Summary: Higher order morphologies, such as rods and worms, can be formed by combining core-shell nanoparticles with boronic acid moieties under basic conditions. For the first time, it is observed that lactate, an anaerobic metabolite, can bind to the BA moiety of amphiphilic block copolymers at a lower physiological pH of 7.4. Self-assembly experiments show that the resulting nanoparticles have similar structures to those formed by reacting with glucose.

Summary: This work introduces a series of novel multi-responsive hyperbranched copolymers which self-organize in aqueous media. The copolymers, prepared by RAFT polymerization, exhibit responsiveness to changes in solution temperature and pH, and are able to encapsulate hydrophobic drugs like curcumin. These hyperbranched copolymers show potential as candidates for drug delivery and bio-imaging applications, as they demonstrate stability in the presence of serum proteins.

Summary: A new approach to construct self-adhesive hydrogels by conducting free radical polymerization in both aqueous and micelle phases is developed, resulting in mechanically strong and adhesive hydrogels for wearable sensors. The introduced ions during preparation process endow the resulting hydrogels ionic conductivity, while resistive strain sensor of the hydrogel achieves a high gauge factor, response time, and sensing stability. Organohydrogels constructed in glycerol-water mixed solvent exhibit outstanding anti-freezing property and moisture retention ability, and their adhesiveness is well maintained in subzero conditions, demonstrating potential in monitoring diverse human motions with capacitive pressure sensors.

Summary: Efficient and stable perovskite solar cells with simple active layers are desirable for manufacturing, but the formation of a two-dimensional component in the perovskite film compromises the performance. In this study, low temperature fabrication of highly efficient and stable inverted solar cells was achieved by adding a fluorinated lead salt, resulting in increased crystal size and orientation, as well as enhanced stability under high humidity conditions.

Summary: This study presents an approach to improve the toughness and self-healing properties of hydrogels by using a graphene oxide-based crosslinker (GOBC). The GOBC is able to form both covalent bonds and noncovalent interactions with the polymer chains of hydrogels, leading to significant improvements in mechanical properties and self-healing efficiency. This crosslinker-based approach has the potential to expand the applications of hydrogels, particularly in the development of artificial tissues.

Summary: Photopolymerization technology is limited in the fields of food packaging and biomedicine due to the high migration of small molecules from photoinitiators. In this study, a polymerizable 2-vinyl thioxanthone (ETX) was synthesized to improve the migration stability of photoinitiators. Macromolecular photoinitiators (PPI1, PPI2) were also prepared to further reduce migration. The results showed that the ETX/TEOA system had higher initiation performance and PPI2 displayed favorable initiation ability. Additionally, the migration of ETX, PPI1, and PPI2 in photocured film was significantly reduced. These low-migration photoinitiators have potential applications in the fields of food packaging and biological materials.

Summary: This study focuses on the development of high-performance, low-migration photoinitiators. A polymerizable photoinitiator (VBP) was synthesized by introducing an ethylene group into benzophenone, and three different molecular weight single-component photoinitiators (PVBN1-3) were synthesized based on VBP. The results show that these new photoinitiators have stronger absorption ability compared to benzophenone and significantly reduce the migration of initiators and co-initiators, addressing the safety concerns caused by migration.

Summary: This study investigates the effect of plasma treatment on carbon nanotubes (CNTs) and the structure/properties of polyimide (PI) nanocomposites with ultra-low content of CNTs. The results show that plasma treatment introduces isocyanate groups on the surface of CNTs and enhances the interfacial interaction between PI and treated CNTs. This leads to a significant improvement in the mechanical properties of the nanocomposites, with even a small addition of treated CNTs showing a substantial increase in Young's modulus, tensile strength and toughness.

Summary: The insertion of rigid aliphatic or aromatic building blocks in polymer structures is an effective way to synthesize high -Tg polymer materials. In this study, a series of isosorbide-2-aryl carboxylate-5-methacrylate monomers (ArIMAs) were synthesized by functionalizing isosorbide 5-methacrylate with various aromatic lignin-inspired esters. These monomers were polymerized to obtain high molecular-weight poly(aryl carboxylate isosorbide methacrylates) (PArIMAs). The resulting polymers showed high glass transition temperatures and thermal stability, making them suitable for use as high-performance plastics and coatings.

Summary: Conductive hydrogels have great development prospects in flexible strain sensors, but long-term direct contact with human skin can cause bacterial infection. A hydrogel with antibacterial, biocompatibility, and toughness was designed and manufactured using a freeze-thaw method. The hydrogel maintains tensile properties and fatigue resistance at low temperatures and is resistant to bacteria. Therefore, hydrogel sensors can be used to monitor human movements.
