Reaction pathways to SnO(2) nanomaterials through the hydrolysis of hydrated tin tetrachloride precursors were investigated. The products were prepared solvothermally starting from hydrated tin tetrachloride and various (e.g., alkali) hydroxides. The influence of the precursor base on the final morphology of the nanomaterials was studied. X-ray powder diffraction (XRD) data indicated the formation of rutile-type SnO(2). Transmission electron microscopy (TEM) studies revealed different morphologies that were formed with different precursor base cations. Data from molecular dynamics (MD) simulations provide theoretical evidence that the adsorption of the cations of the precursor base to the faces of the growing SnO(2) nanocrystals is crucial for the morphology of the nanostructures.

Sulfur dioxide (SO), a pervasive air pollutant, poses significant environmental and health risks, necessitating advanced materials for its efficient capture. Nanoporous organic polymers (NOPs) have emerged as promising candidates; however, their development is often hindered by high synthesis temperatures, complex precursors, and limited SO selectivity. Herein, we report a room-temperature, cost-effective synthesis of carbazole-based nanoporous organic polymers (CNOPs) using 1,3,5-trioxane and paraldehyde, offering a significant advancement over traditional Friedel-Crafts alkylation methods.

Article Synopsis
- Lipid droplets (LDs) are crucial organelles for lipid storage and metabolism in cells, and imaging them can reveal their biological roles.
- Researchers developed LD-targeted carbon dots (LD-CDs) using a Schiff base reaction, which exhibit strong sensitivity to changes in solvent polarity due to their unique charge transfer characteristics.
- These LD-CDs not only specifically illuminate LDs and distinguish cancer cells from normal ones but also track dynamic cellular processes like lipophagy and lipid metabolism in living cells and zebrafish.

Background And Aims: Current gastric cancer (GC) screening modalities are invasive and expensive. Noninvasive screening for GC precursors with serum pepsinogen (PG) may improve early detection and prevention. Test characteristics of PG based on US prospective data was recently reported and used to study the cost-effectiveness of PG screening vs no screening in the US.
