Summary: Sugar-based amphiphiles are a natural alternative to synthetic ones with biodegradable properties. An investigation of their structure-assembly relationship was conducted using various techniques in aqueous media. The results showed that the average degree of polymerization (DP) and the addition of a hydroxyl group to the hydrophobic tail affected their self-assembly. The critical micelle concentration was more influenced by changes in the hydrophobic molecular region than by variations in (DP) over bar. Amphiphiles with high (DP) over bar formed spherical micelles regardless of the presence of a hydroxyl group, while those with low (DP) over bar and only one hydrophilic moiety formed cylindrical micelles, and the addition of a hydroxyl group to the tail resulted in a spherical shape.

Summary: In this study, different ratios of charged-neutral diblock ELPs and a neutral ELP were synthesized and their physical properties were investigated. The self-assembly behavior of ELPs in deionized water and NaCl solutions was studied using various analytical instruments. The results showed that the charged-neutral diblock ELPs formed hydrophobic core micelles in NaCl solutions, while the neutral ELP aggregated in both deionized water and NaCl solutions.

Summary: Research indicates that block copolymers with chemically different bottlebrush blocks can self-assemble into nanostructures resembling micelles in selective solvents. The self-consistent field theoretical approach is utilized to predict the relationship between structural parameters of bottlebrush blocks and properties of micelles, including critical micelle concentration. Theoretical predictions suggest that replacing linear blocks with bottlebrush ones of the same polymerization degrees leads to changes in micellar core size and corona extension, as well as an increase in critical micelle concentration, which are in agreement with computer simulation results.

Summary: Hierarchically structured polymeric colloids were rapidly produced by confined self-assembly of bottlebrush random copolymers in evaporative emulsion droplets. The internal structures of the particles developed instantaneously during the early stage of solvent evaporation due to the confinement effect and fast-assembling polymer architecture. Different particle morphologies were achieved by adjusting the volume fraction of copolymers.

Summary: The self-assembly kinetics of short-chain glucan aggregates prepared under isothermal conditions were investigated. The formation and crystallization rates were fastest at 4°C and 20°C. Nucleation allowed for the formation of aggregates at 60°C, and increased yield at all temperatures. All aggregates exhibited B-type crystal patterns and nanosized particles (<500 nm). Manipulation of the nucleation step is expected to be an effective method for increasing yield and producing aggregates at high temperature.

Summary: Hierarchical bishell capsules (BCs) with ultrathin lamellar phases have been prepared through a coacervate-assisted polymerization-induced self-assembly (CAPISA) method, which combines liquid-liquid phase separation (LLPS) with polymerization-induced self-assembly (PISA). The CAPISA method allows for the one-pot and scalable preparation of BCs in a bottom-up sequence, and the self-assembled structure and dynamic formation process of BCs have been revealed. CAPISA shows great potential in fabricating biomimetic polymer materials with higher structural complexity and sophisticated functions.

Summary: In this study, the microphase-separation behavior and mechanical properties of cellulose- and amylose-based block copolymers were compared. It was found that cellulose-based block copolymers are more likely to form ordered nanostructures and show superior mechanical performance under tensile testing compared to amylose counterparts. This enhanced performance was attributed to the stiffness and crystalline nature of the cellulose segments.

Summary: The study reveals that mixtures of polypeptide homopolymers and block copolymers can form superhelices with tunable chirality. The chirality of the superhelices can be regulated by the chiralities of the homopolymers and copolymers. A mechanism explaining the origin of superhelical chirality is proposed based on experimental observations. This work deepens the understanding of superhelix chirality and provides guidance for the construction of hierarchical nanostructures with controllable chirality.

Summary: Introducing a second component is an effective way to manipulate polymerization behavior. However, this phenomenon has rarely been observed in colloidal systems, such as polymeric nanoparticles. Here, we report the supramolecular polymerization of polymeric nanorods mediated by block copolymers. Experimental observations and simulation results illustrate that block copolymers surround the polymeric nanorods and mainly concentrate around the two ends, leaving the hydrophobic side regions exposed. These polymeric nanorods connect in a side-by-side manner through hydrophobic interactions to form bundles. As polymerization progresses, the block copolymers gradually deposit onto the bundles and finally assemble into helical nanopatterns on the outermost surface, which terminates the polymerization. It is anticipated that this work could offer inspiration for a general strategy of controllable supramolecular polymerization.

Summary: Precise control of size and dimension is crucial for constructing complex hierarchical nanostructures. Brownian dynamics simulations revealed that 2D-1D hybrid micelles can be formed via liquid-crystallization-driven self-assembly. The structural transition of the micelle core and the sequential generation of cylindrical arms provide explanations to some unaddressed issues in experiments. The hybrid micelles also exhibit high surface area and distinctive suspension behaviors, making them a good stabilizer.

Summary: Polymers can be attached to nanoparticles either dynamically or permanently, resulting in polymer-functionalized nanoparticles. The mobility of polymer brushes anchored to nanoparticles can affect surface patterns, but the impact is unclear. This study used self-consistent field theory calculations to investigate the influence of lateral polymer mobility on surface patterning. The results demonstrated that the fraction of mobile brushes significantly influences the surface patterning of polymer-functionalized nanoparticles. This work provides a fundamental understanding of the dependence of surface patterning on lateral polymer mobility.

Summary: Traditional material design principles for thermosetting polymers are inefficient due to conflicting properties. Machine learning combined with limited experimental data and all-atomic simulations can establish robust property estimation models. Virtual candidates are screened and promising polycyanurates are identified through well-trained ML models, verified by theoretical simulations and proof-of-concept experiments. The proposed framework can accelerate the rational design of polymers and reveal underlying physical rules.

The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
