Article Abstract
In this study the influence of viscosity and chemical nature of dispersed phase, preparation conditions and storage temperature on the properties of nitrocellulose emulsions produced by gel emulsification (G) and direct mechanical emulsification (D) methods were examined. Chemical nature of dispersed phase had no effect on the drop size for both methods; however it had a significant effect on emulsion stability. Viscosity of dispersed phase did not considerably affect drop breakage process in route G, while strongly affected drop breakage in route D. Addition rate had no significant effect on the drop size produced by route D; while for route G high addition rate resulted in catastrophic phase inversion. The drop size produced by route D decreased dramatically by increasing stirring speed, whereas stirring speed had a minimal effect on the drop breakage process in route G. Finally, it was found that emulsion stability was greatly influenced by storage temperature.

Lithium metavanadate (LiVO) is a material of growing interest due to its monoclinic 2/ structure, which supports efficient lithium-ion diffusion through one-dimensional channels. This study presents a detailed structural, electrical, and dielectric characterization of LiVO synthesized a solid-state reaction, employing X-ray diffraction (XRD), scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS), and impedance/dielectric spectroscopy across a temperature range of 473-673 K and frequency range of 10 Hz to 1 MHz. XRD and Rietveld refinement confirmed high crystallinity and single-phase purity with lattice parameters = 10.

This study focuses on developing an analytical method to efficiently extract and concentrate several adipate and phthalate plasticizers that can migrate from plastic packaging into various wound disinfectants. The study employed an approach that combined dispersive micro solid phase extraction with dispersive liquid-liquid microextraction using ZIF-4 as an adsorbent. The adsorbent was thoroughly characterized to understand its properties.

Lemon balm (), a perennial herb belonging to the Lamiaceae family, is widely recognized for its medicinal properties and therapeutic benefits. This review offers a detailed exploration of the botanical features, phytochemical composition, and pharmacological uses of , highlighting key bioactive compounds such as phenolic acids (including rosmarinic and caffeic acids), flavonoids, essential oils (such as citral and citronellal), and triterpenoids (ursolic and oleanolic acids). Advanced extraction techniques, such as ultrasound-assisted extraction (UAE), microwave-assisted extraction (MAE), pressurized liquid extraction (PLE), supercritical fluid extraction (SFE), and matrix solid-phase dispersion (MSPD), have greatly improved the efficiency of extraction, the preservation of bioactivity, and the sustainability of acquiring these bioactive compounds.

Organic molecular glasses are attractive matrices to disperse active ingredients in pharmaceuticals or electronic devices. Typically, they i) have lower glass transition temperatures than inorganic or polymeric glasses, making them easier to process, and ii) are less prone to phase segregation from other organic active materials. However, there is a dearth of functional groups that are known to induce glass formation in preference to crystallization.

Geopolymers are aluminosilicate materials that exhibit effective immobilization properties for low-level radioactive nuclear waste, and more specifically for the immobilization of radioactive cesium. The identification of the cesium-binding sites and their distribution between the different phases making up the geopolymeric matrix can be obtained using solid-state NMR measurements of the quadrupolar spin Cs, which is a surrogate for the radioactive cesium species present in nuclear waste streams. For quadrupolar nuclei, acquiring two-dimensional multiple-quantum experiments allows the acquisition of more dispersed spectra when multiple sites overlap.
