Summary: A series of injectable polysaccharide hydrogels were prepared using oxidized dextran and diethylenetriamine-modified carboxymethylcellulose (CMC) or hyaluronic acid (HA). The rheological evaluation showed that CMC-based hydrogels have higher storage moduli than HA-based hydrogels. The incorporation of N-diazeniumdiolate nitric oxide (NO) donors into the hydrogels reduced their storage moduli and increased the rate of degradation.

Summary: The use of self-healing hydrogels in wound dressings can protect them from mechanical damage and extend their lifespan. In this study, a hydrogel with rapid self-healing properties and high antibacterial activity was fabricated by testing different mixing ratios of hyaluronic acid (HA) and pectin (PT) using Fe3+ cross-linking. The optimal Fe3+-cross-linked HA/PT hydrogel showed potential for wound-healing applications due to its self-healing properties and antibacterial activity against Staphylococcus aureus and Pseudomonas aeruginosa.

Summary: Interpenetrating polymer networks (IPNs) were prepared through dual-network formation, one of which was derived from pre-formed nanogels. The study found that controlling the loading level of different nanogels can result in homogeneous morphologies of IPNs, with no compromise in the bulk IPN modulus or strength when incorporating nanogels with urethane linkages.

Summary: This study presents the design and characterization of an in situ-forming semi-interpenetrating polymer network (SIPN) hydrogel, using commonly used biomaterials in ophthalmology and medicine. The SIPN hydrogel showed mechanical and optical properties similar to the cornea, and demonstrated biocompatibility with human corneal cells. In vivo application of the SIPN hydrogel resulted in significant reduction of stromal defect size and promotion of epithelial regeneration. This SIPN hydrogel could be a promising alternative to keratoplasty for treating corneal injury.

Summary: In this study, a thermosensitive hyaluronic acid-g-poly(N-isopropylacrylamide) copolymer was synthesized and found to have sol-to-gel phase transition temperatures suitable for use as a scaffold for chondrocyte delivery. In vitro cell culture experiments showed that cells could proliferate in the polymer scaffold with full retention of cell viability and exhibit the phenotypic morphology of chondrocytes. In vivo studies confirmed the formation of ectopic cartilage when the polymer was used as a cell delivery vehicle. These findings suggest the promising potential of the thermosensitive hydrogel in cartilage tissue engineering applications.

Summary: Since Taylor's seminal work in 1923, Taylor-Couette flow has been widely studied to understand hydrodynamic instabilities and bifurcation phenomena. In recent years, there has been growing interest in studying TC flows with complex, viscoelastic fluids. The transitions to elastic turbulence or elasto-inertial turbulence have revealed fascinating dynamics and flow states. However, the nature of these transitions and the relationship between elastic turbulence and elasto-inertial turbulence are not fully understood.

Summary: The role of elasticity on the flow topology inside viscoelastic (Boger) droplets moving in a rectangular micro-channel is experimentally examined using micro Particle Image Velocimetry (μPIV). The results show that varying the Wi number alters the flow topology inside the droplets, and when the Wi and elastic number increase, a new flow structure is observed characterized by two recirculating regions. These findings highlight the importance of elasticity in microdroplet flows and the potential of tuning elasticity for microfluidic applications.

Summary: This study focuses on the use of reduced order models (ROMs) to reconstruct velocity fields in a patient-specific dissected aorta, comparing ROMs obtained from robust and traditional proper orthogonal decomposition (POD). Results show that robust POD enhances the quality of the data and fewer modes are needed to capture the kinetic energy of the flow. The study also finds that the coherent structures of the aortic dissection flow can be described by a small number of POD modes, simplifying the problem.

Summary: This study describes the development of a scalable human induced pluripotent stem cell (iPSC)-neuromuscular disease model, whereby suspended elastomer nanofibers support long-term stability, alignment, maturation, and repeated contractions of iPSC-myofibers, innervated by iPSC-motor neurons in 96-well assay plates. Optogenetic stimulation of the motor neurons elicits robust myofiber contractions, providing a functional readout of neuromuscular transmission. This platform can be used to screen novel treatments for neuromuscular diseases.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Multi-layer architectures comprising CNT-rich and CNT-free LTO electrode layers were manufactured using a layer-by-layer spray coating method to promote charge transfer kinetics of high mass loading electrodes. The best performing multi-layer was paired with a spray-coated LiFePO4 (LFP) positive electrode, resulting in attractive power performance that outperformed conventional LTO || LFP combinations.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
