Halide solid electrolytes receive much attention due to their electrochemical properties, such as high ionic conductivity, oxidative stability, and ease of preparation. In this work, a bromide solid electrolyte LiBiBr, exhibiting ease of processing and high ionic conductivity, is designed for the first time and investigated through a comparative investigation with monoclinic LiAlCl and LiAlBr for the migration path. The processing pressure for LiBiBr with annealing at 120 °C is less than one-tenth that of other chloride electrolytes (≈5 MPa). Computational analyses unveil crucial mechanistic insights into the three migration mechanisms and the factors that influence them within the monoclinic structure. The distribution and distance of non-Li polyhedrons to the migration pathways are pivotal for the migration. The strategic positioning of the Bi polyhedron in LiBiBr is far from the Li pathway. The unique leap migration within the LiBiBr has a lower energy barrier and facilitates an interconnected migration that forms a 3D interstice network. This interconnected leap migration network within LiBiBr constitutes a Z-type interstice leap migration along the ab-axis. Thus, the LiBiBr obtains a high ionic conductivity of 0.19 mS cm with the 0.349 eV low activation energy. This discovery and research methods provide significant impetus and support for the development of halogen-based electrolytes.

Gene therapy, a pivotal cornerstone in biomedical research, has emerged as a transformative approach for addressing a wide spectrum of dermatologic conditions, including hereditary disorders, chronic wounds, and immune related skin diseases. The skin, with its expansive surface area and regenerative capacity, serves as an ideal platform for localized gene delivery. However, conventional gene therapy strategies face critical limitations, such as high costs, suboptimal transfection efficiency, immunogenicity, and off-target effects.

Background: Efferocytosis (ER) plays a crucial role in the programmed clearance of dead cells, a process that is mediated by phagocytic immune cells. However, further exploration is needed to determine the full extent of its impact on the progression of pancreatic ductal adenocarcinoma (PDAC), particularly through interactions among tumor cells, stromal cells, and immune cells within the tumor microenvironment (TME).
Methodology And Results: In this study, we comprehensively analyzed the Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) database, as well as additional databases from multiple bioinformatics websites, utilizing 167 ER features derived from the integration of single-cell RNA sequencing (scRNA-seq) and bulk transcriptomic data.

Tertiary lymphoid structures (TLSs) are de novo ectopic lymphoid aggregates that regulate immunity in chronically inflamed tissues, including tumours. Although TLSs form due to inflammation-triggered activation of the lymphotoxin (LT)-LTβ receptor (LTβR) pathway, the inflammatory signals and cells that induce TLSs remain incompletely identified. Here we show that interleukin-33 (IL-33), the alarmin released by inflamed tissues, induces TLSs.
