The interactions between these cells and the signals in the microenvironment play a crucial role in determining tumor behavior. A novel functional model has been developed to mimic the biological, chemical, and contextual cues of a tumor in vivo, allowing for a better understanding of tumor progression and spread within the microenvironment.

Summary: This study investigates the impact of covalent modification on the self-assembly of a quinonoid zwitterion derivative. It is found that covalent modification can induce the formation of self-assembled structures at low concentrations, where no self-assembly behavior is observed on the bare surface. The size of the self-assembled domains decreases with increasing the density of grafted molecules, and the dynamics of domains, including growth, shrinkage, and orientation conversion, are captured with molecular resolution.

Summary: Lipids play a crucial role in regulating bodily functions and providing energy, primarily entering the body as triglycerides through diet. Certain lipids have been found to promote the formation of highly ordered colloidal structures during gastrointestinal digestion, impacting nutrient absorption. This process has implications for drug delivery, enabling the solubilization of poorly water-soluble drugs in the gut for absorption.

Summary: High energy density batteries with lithium metal as the anode have great potential for applications in electric vehicles and energy storage stations. However, interface/interphase issues within the electrochemical cell have hindered their high performance. Polymer-based interface/interphase engineering has proven to be an effective solution, involving rational structure design and flexible processing methods. This review summarizes and discusses the interface/interphase issues in different battery components, such as the cathode, separator, and anode, and explores the use of functional polymers to address these issues, including polysulfide diffusion, structural instability, and lithium dendrite growth. The microenvironment of the cathode's active material is also emphasized for a comprehensive understanding of the interface/interphase issues. The review concludes by discussing the remaining challenges and future prospects for next-generation high-energy-density batteries.

Summary: In this research, a polyolefin elastomer (POE) and paraffin wax (PW) were co-cross-linked by dynamic boronic ester bonds to enhance the network elasticity and stress transfer, enabling high force storage in shape memory polymers (SMPs). One-way force storage was achieved by programming at a low temperature (25 °C) through solid PW, while reversible force storage was achieved at a high temperature (75 °C) through liquid PW. The POE/PW vitrimers also exhibited mold-free self-healing and improved repair efficiency, making them suitable for soft robotic actuators.

Summary: A polyolefin elastomer vitrimer (POEV) was prepared by constructing a dynamic cross-linked network based on boronic ester bonds. The controllable relaxation of POEV by temperature enables the actuation domain with a reduction in entropy and the skeleton domain with a relatively high entropy, greatly affecting the reversible shape memory effects (RSMEs). By combining the decreasing entropy of POEV chains and topological rearrangement, hybrid aligned carbon nanotubes (CNTs) can be constructed in POEV, enhancing its elasticity and acting as a hybrid skeleton for RSMEs.
