Lead-free electroceramics have attracted significant research interest as alternatives to lead-containing systems due to concerns related to lead's toxicity to human health and the environment. Solid solutions based on bismuth sodium titanate (BNT) and barium titanate (BT), particularly those with compositions near the morphotropic phase boundary (MPB), such as 0.94 BiNaTiO-0.

Bacterial infection in the injured skin may threaten the wound repair and skin regeneration owing to aggravated inflammation. The multifunctional dressings with persistent antibacterial activity and improved anti-inflammatory capability are urgently required. Herein, a type of heterogeneous zinc/catechol-derived resin microspheres (Zn/CFRs) composed of zinc ions (Zn) and zinc oxide (ZnO) nanoparticles was developed to impart the methacrylamide chitosan (CSMA)-oxidized hyaluronic acid (OHA) hydrogel with a persistent Zn release behavior.

Understanding hydrogen bonding and ion-specific interactions in water, sodium sulfate (NaSO), and acetonitrile (ACN) systems remains challenging due to their complex, dynamic nature. Here, Raman spectroscopy is employed to probe hydrogen bonding networks and ion reorganization in NaSO aqueous solutions with different ACN concentrations. The results indicate that, at low ACN concentrations in the ternary solutions, hydrogen bonding between ACN and water molecules disrupts the original hydration structure of the ions, resulting in the formation of small ion clusters via electrostatic interactions.

Herein, organic/inorganic multiple adsorption sites were constructed on halloysite to intensify the selective adsorption performance of the adsorbent for Al(III) in rare earth solutions. The adsorption heat behavior and thermodynamics of the composite for different ion systems were investigated using microcalorimetry. The results showed that chitosan formed a mesoporous membrane on the acid-treated calcined halloysite (HalH) substrate through a strong electron interaction between the nitrogen atom of the amino group and the oxygen atom of SiO structure on HalH.

The gas-phase structures of dibenzo-24-crown-8 (DB24C8) and dinaphtho-24-crown-8 (DN24C8) complexes with divalent metal ions (Mg, Ca, Sr, Ba, Fe, Ni, and Zn) were investigated by cryogenic ion mobility-mass spectrometry (IM-MS) in combination with density functional theory calculations. Several complexes, particularly those of DN24C8, exhibited multiple coexisting conformers. DFT-optimized structures were classified based on the relative orientation of the two aromatic rings in the crown ether.
