Removal of accumulated dyes from the environment water bodies is essential to prevent further harm to humans. The development and design of new alternative nanoadsorbents that can conveniently, quickly, and efficiently improve the adsorption and removal efficiency of dyes from wastewater remains a huge challenge. An amorphous TiO with a magnetic core-shell-shell structure (FeO@PDA@a-TiO, denoted as FPaT) was constructed through a series of steps.

Room-temperature sodium-sulfur (RT Na-S) batteries that typically feature multielectron conversion chemistries can allow an ultrahigh specific capacity of 1675 mA h g and a high energy density of 1275 W h kg but unfortunately suffer from a lot of intractable challenges from sulfur cathodes. These issues cover the poor electronic conductivity of pristine sulfur and solid products, the severe shuttle effect of polysulfides, and the sluggish redox kinetics, The shuttling behavior of polysulfides always leads to cathode/anode instability and performance degeneration. Recently, the emerging catalysis strategy has been demonstrated as a reliable pathway to tackle the central issues caused by sulfur electrochemistry and revitalize RT Na-S batteries.

The cellular characteristics of the opportunistic fungal pathogen Cryptococcus species were investigated in the infected liver of an immunocompetent host using transmission electron microscopy (TEM). With no records of immunodeficiency, the 3-year-old female patient displayed a high-grade fever, lethargy, and increasing jaundice. TEM analysis revealed the presence of round yeast cells in the patient's liver.

High-performance acoustic resonators based on single-crystalline piezoelectric thin films have great potential in wireless communication applications. This paper presents the modeling, fabrication, and characterization of laterally excited bulk resonators (XBARs) utilizing the suspended ultra-thin (~420 nm) LiTaO (LT, with 42° YX-cut) film. The finite element analysis (FEA) was performed to model the LT-based XBARs precisely and to gain further insight into the physical behaviors of the acoustic waves and the loss mechanisms.

Waterborne polyurethane, with a mechanical strength comparable to solvent-based types, is eco-friendly and safe, using water as a dispersion medium. Polyacrylate excels in film formation and weather resistance but suffers from "hot stickiness and cold brittleness". Merging polyurethane and polyacrylate creates advanced hybrids, while organosilicon enhances properties but is restricted due to hydrolytic crosslinking.
