The study developed octenyl succinylated (OS) potato starch complexes with ethanolic extracts of honey bee products (HBE) and assess their effects on starch-based films properties. X-ray diffraction and thermogravimetric analysis showed that OS starch films had lower crystallinity and higher thermal stability than native ones. Adding HBE enhanced V-type ordering in OS films.

- - The study explored how different amounts of furcellaran and safflower oil impact the properties of emulgels, which could be used to carry bioactive substances.
- - Findings revealed that increasing furcellaran concentration while reducing safflower oil enhanced the hardness and thermal stability of the emulgels, but oil addition weakened the overall structure.
- - The microstructure analysis showed that most safflower oil was physically trapped in the furcellaran matrix, and the color of the emulgels varied with the oil content, laying the groundwork for future research on creating effective carriers for lipophilic compounds.
Lead-free KBiTiO (KBT) ceramics with high density (~5.36 g/cm, 90% of X-ray density) and compositional purity (up to 90%) were synthesized using a solid-state reaction method. Strongly condensed KBT ceramics revealed homogenous local microstructures.

As non-magnetic Eu ions are replaced by Pr carrying a magnetic moment, spin-related superconductivity loss can be expected. The research shows that the superconductivity disappearance for > 0.
