Summary: The study found that three structurally flexible cages exhibit high binding affinities and selectivities to different guests, with enthalpy-entropy compensation used to explain the variations in binding performance. Furthermore, a six-component, high-fidelity self-sorting system was successfully constructed using these cages and three guests, highlighting the potential of conformationally flexible hosts to achieve high binding affinities and selectivities.

Summary: This study found that tamarind seed polysaccharide (TSP) effectively inhibits ice recrystallization. Lowering the molecular weight of TSP enhances its activity and adding TSP to water reduces the melting temperature of ice. Raman spectra indicate that TSP disrupts the hydrogen bond network of water. These findings suggest the potential of TSP as a novel food cryoprotectant and contribute to a better understanding of the antifreeze mechanism of natural polysaccharides.

Summary: Solar-assisted distillation using a passive and flexible multistage membrane distillation device is able to produce freshwater efficiently by recycling the latent heat of vapor condensation. The device solves the challenge of salt accumulation by utilizing a siphon effect to continuously deliver source water and remove concentrated brine. By using recycled paper as the evaporation layer, the device achieves a stable clean water production rate, providing a green route for designing solar-assisted distillation devices.

Summary: This study proposes a smartphone-based indoor positioning algorithm that achieves flexible localization between different phone poses and motion modes by enhancing the robustness and smoothness of pedestrian tracking. The algorithm uses a Bayesian-based approach for real-time recognition of multiple modes and a time-series decomposition method for adaptive tracking scheme switching. Experimental results demonstrate that the algorithm achieves high accuracy indoor positioning in situations with frequent mode switching.

Summary: The tetracationic cyclophane, known as the little blue box, is valuable in constructing stimuli-responsive materials by binding small pi-donors and forming complexes with viologen radical cations. Its significance in the discovery of host-guest complexes and mechanically interlocked molecules is highlighted.

Summary: Understanding the antifreeze activity is crucial for developing new antifreeze agents. Previous studies have mainly focused on the ice binding affinity of additive molecules but have neglected their influence on the hydrogen bonding network of ice. In this study, we investigate the ice recrystallization inhibition (IRI) activity of two structurally similar molecules, histidine (His) and phenylalanine (Phe), and explore the origin of their difference through molecular dynamics simulation. We propose a method to evaluate the order of the hydrogen bonding network, which allows us to interpret the IRI activity of His and Phe and quantify the influence of different groups on the hydrogen bonding network.

Summary: Assembling nanobodies into polyvalent multimers is an effective strategy for improving the efficacy of antibody drugs and biotechnological tools. By site-specifically inserting reactive tetrazine groups on the nanobody surface, assembly can be achieved at any desired point, resulting in improved properties compared to conventional methods.

Summary: Design and synthesis of a series of photochromic molecules with different free volume groups were conducted in this study to improve the color sensitivity and reversibility of functional materials in the solidified state. It was found that the photosensitivity of the molecules increased with the increase of molecular free volume. The designed photochromic molecules were successfully applied to polyester fabrics, resulting in photochromic materials with excellent photosensitivity and good reversibility, which have potential applications in smart textiles, optical devices, anti-counterfeiting, etc.

Summary: The study found that the haplotype HLA-DRB1*13:02-DQB1*06:04 was less frequent in high-responders vaccinated with Heptavax-II in Japan, indicating lower antibody titers. Additionally, 15 residues in the Heptavax-II-derived antigenic peptide were predicted to have the most unstable HLA-peptide binding. This suggests potential implications for vaccine efficacy and understanding liver disease mechanisms.

Summary: Observations with the Herschel telescope show a significant amount of water in young stellar objects, requiring calculation of excitation rate coefficients for water collisions with H2 at high temperatures. These new collisional data will provide further insight into the physical conditions of star- and planet-forming regions, especially with the upcoming launch of the James Webb Space Telescope.

Summary: A novel pillar[5]arene-bridged monomer with TPE and nitrile group was synthesized and it formed supramolecular aggregates based on the host-guest interaction. The supramolecular aggregates exhibited significant aggregation-induced emission due to the restricted intramolecular rotation of the TPE core.
