Summary: Lipid molecules form the backbone of biological membranes and self-organize into various structures depending on the shape factor or critical packing parameter, CPP. The value of CPP predicts the type of self-assembled structure and affects molecular interactions, playing a significant role in physiological and pathological conditions. Using molecular dynamics, a method has been developed to successfully determine packing parameters for different membrane lipids and amphiphilic molecules.

Summary: The self-assembly of hybrid colloids, driven by chemical concentration gradients generated by photocatalytic reactions, is investigated. Different shapes of the colloids lead to the formation of assemblies with distinct lattice structures, validated by computer simulations. Moreover, the assemblies transition from lattices to chains as the attraction between the colloids increases. These findings demonstrate the unique capability of photoresponsive hybrid colloids in shape-dependent self-assembly, offering a practical and versatile approach to control self-assembly at the microscale.

Summary: Researchers have successfully designed two-dimensional assemblies with structural complexity by utilizing the distinct interfacial morphology of soft particles. They found that core-shell particles can form complex chain and cluster structures under interfacial compression. Through a combination of experimental, simulation, and theoretical analysis, the interaction parameter of the system was narrowed down to between 0.9 and 2.

Summary: This review article discusses various methods and formalisms for analyzing the equilibrium distribution of ligands in the presence of proteins, lipid membranes, or both, with special attention to common pitfalls and validity limits of different approaches. The analysis of ligand binding through Stern-Volmer plots of protein fluorescence quenching is emphasized for its widespread use in characterizing interactions. Different systems of increasing complexity are considered, from proteins with single to multiple binding sites to membrane proteins in lipid bilayers.

Summary: This article explores new design principles for making self-limiting architectures using self-assembly. The authors use DNA origami to create triangular subunits with specific interactions and binding angles, and study their assembly into tubules with a self-limited width. They demonstrate that the tubules can reach significant lengths and that their width can be controlled through geometric programming. They also find that the width and chirality of the tubules can be manipulated by increasing the number of subunit species. These findings provide insights into the role of assembly complexity and geometry in self-limiting assembly and have potential applications in other self-limiting architectures.

Summary: This study simulated 15 molecular systems to characterize the interactions between PAMAM dendrimers and membranes with different cholesterol ratios, explaining the structural features and geometry of their activity against cancer cells. The results demonstrated that cholesterol content in the membranes influenced the local membrane order parameters, and the dendrimers were able to create holes in cholesterol-containing membranes through hydrogen bonds and electrostatic interactions. Additionally, negatively charged phospholipids in cancer cell membranes played a crucial role in binding with the dendrimers, providing mechanistic insight into their activity against cancer cells.

Summary: Stereochemistry in polymers plays a significant role in controlling the mechanical and physical properties of materials. This study demonstrates that stereochemical differences in sugar-based monomers can result in a family of nonsegmented, alternating polyurethanes with exceptional properties. The behavior of these polymers is defined by distinct intra- and interchain supramolecular hydrogen-bonding interactions. The chemical similarity among these polymers allows for independent control over degradability and mechanical properties through statistical copolymerization and blending.

Summary: This study investigates the effectiveness of three machine/deep learning algorithms (artificial neural network, convolutional neural network, and U-shape neural network) in constructing wind turbine wake modeling. By adopting the spatial-segmentation technique, the prediction error of wake velocity can be significantly reduced. Among the selected network structures, the artificial neural network has the best prediction performance. However, the prediction error of turbulence intensity field is higher but still fairly accurate for the far wake prediction.

Summary: This study investigates the electronic properties of a rationally designed superatomic crystal ATS through a combination of experimental and theoretical approaches. The results reveal the presence of anisotropic triple-cube charge density wave and polarized metallic states at lower temperatures. These findings not only provide a microscopic picture of the interweaved charge order and polarized states in ATS superatomic crystals, but also have implications for expanding the category of quantum materials to noncovalent solids.

Summary: This paper presents a novel static fluid-structure interaction (FSI) tool based on deep learning to cost-efficiently analyze the fluid-structure coupling of a hydrofoil. By adopting a convolutional neural network (CNN) to predict the fluid force and finite element method (FEM) to solve the solid structure response, a new CNN-FEM framework with an iterative scheme for solving the FSI problem is developed. The results show that this method yields extremely close prediction results and is 100 times more computationally efficient than the commercially developed software (Ansys Workbench).

Summary: In this study, the temperature evolution of the band structures of ZrTe5 was investigated using angle-resolved photoemission spectroscopy. Two distinct types of band shift with temperature were observed. By assuming ZrTe5 is a semiconductor with a limited amount of impurities, the discrepancies in band structures and the controversial results on temperature-dependent band shifts were explained in a unified picture.

Summary: High-resolution angle-resolved photoemission spectroscopy was used to investigate the 3D charge-density wave transition in 1T-VSe2, revealing comprehensive evidence of 3D Fermi surface nesting. The variation in photon energy led to observations of Fermi surface warping and nesting conditions along the K-z direction. The larger value of 2 Delta/k(B)T(c) = 14.76 and gap correspondence suggest a combined effort in the formation of CDW in this material beyond the weak-coupling region.
