Inhibiting Lattice Distortion of Ultrahigh Nickel Co-Free Cathode Material for Lithium-Ion Batteries.
Nano Lett

Ultrahigh nickel cathode materials are widely utilized due to their outstanding energy and power densities. However, the presence of cobalt can cause significant lattice distortion during charge and discharge cycles, leading to the loss of active lithium, the formation of lattice cracks, and the emergence of a rock salt phase that hinders lithium-ion transport. Herein, we developed a novel cobalt-free, aluminum-doped cathode material, LiNiMnAlO (NMA), which effectively delays the harmful H2-H3 phase transition, reduces lattice distortion, alleviates stress release, and significantly enhances structural stability.

The properties and functions of metal-organic frameworks (MOFs) can be tailored by tuning their structure, including their shape, porosity and topology. However, the design and synthesis of complex structures in a predictable manner remains challenging. Here we report the preparation of a series of isomeric pillar-layered MOFs, and we show that their three-dimensional topology can be controlled by altering the layer stacking.

Macrocyclic supramolecular materials play an important role in encapsulating anticancer drugs to improve the anticancer efficiency and reduce the toxicity to normal tissues through host-guest interactions. Among them, pillar[n]arenes, as an emerging class of supramolecular macrocyclic compounds, have attracted increasing attention in drug delivery and drug-controlled release due to their high biocompatibility, excellent host-guest chemistry, and simplicity of modification. In this review, we summarize the research progress of pillar[n]arene-based supramolecular nanodrug delivery systems (SNDs) in recent years in the field of tumor therapy, including drug-controlled release, imaging diagnostics and therapeutic modalities.

Knowledge about how and where proteins interact provides a pillar for cell biology. Protein proximity-labeling has emerged as an important tool to detect protein interactions. Biotin-related proximity labeling approaches are by far the most commonly used but may have labeling-related drawbacks.

Opioids represent one of the key pillars in postoperative pain management, but their use has been associated with a variety of serious side effects. Thus, it is crucial to investigate the timing and course of opioid administration in order to ensure a best efficacy to side-effect profile. The aim of our article was to investigate the analgesic effects of locally administered morphine sulfate (intraplantar) in a carrageenan-induced inflammation model in rats.
