Summary: In this study, a novel supramolecular polymer based on pillar[5]arene macrocycles was reported. This fluorescent polymer exhibits a prominent blue emission without conventional chromophores. The emission peak can be slightly tuned through the modification of alkyl chain ending groups attached to the pillar[5]arenes. This study expands the application of functional supramolecular polymer systems and provides valuable insights for the design of luminescent materials and optical devices.

Summary: The main challenges in near-infrared region molecular fluorophores are poor water solubility and unknown long-term toxicity. New NIR-II molecular fluorophores have been designed and synthesized, which integrate biocompatible pillar[5]arene and possess aqueous solubility and lowered cellular toxicity. These fluorophores exhibit room-temperature emission, good chemical stability and reasonable self-assembled sizes, showing potential applications in NIR-II imaging.

Summary: Metal nanoparticle catalysts have high surface-to-volume ratios and a large number of active sites, but they often aggregate during catalytic reactions, leading to a decrease in catalytic activity. In this study, a monoterpyridine-unit-functionalized pillar[5]arene was synthesized and used as anchoring sites for the preparation of well-dispersed palladium nanoparticles. The as-prepared nanoparticles were characterized and found to be excellent and reusable catalysts for the reduction of nitrophenols in aqueous solution.

Summary: An efficient strategy to enhance charge transport in pillar[5]arene self-assembled monolayers (SAMs) by introducing cationic guests is reported. The current density of pillar[5]arene SAMs can be significantly increased by inserting cationic molecules into the cavity of pillar[5]arenes. Furthermore, a positive correlation between the charge transport and binding affinities of pillar[5]arene-based complexation is observed. The enhancement of charge transport is attributed to the efficient host-guest interactions that stabilize the supramolecular complexes and lower the energy gaps for charge transport.

Summary: Despite the breakthrough of immunotherapy, immune checkpoint inhibitors often have low response rate and resistance towards solid tumors. A hypoxic tumor microenvironment provides tumor cells with high concentrations of HIF-1 and polyamines to evade immune cell destruction. Reprogramming the immunogenic microenvironment has shown promising results in boosting immunotherapeutic performances.

Summary: This study introduces a stimuli-responsive invisible ink for time-dependent encryption of information, which displays time-dependent photochromic behavior with tailorable fading rates by controlling the density of host-guest crosslinks. Encryption security of information is achieved through selectively placing host and guest competitors and UV patterning, providing an initially false image that gradually reveals the encrypted data.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
