Simultaneously, the relationship between the preparation process, structural, and performance characteristics of the different resin types was investigated using a single-factor experimental approach, specifically, the solid content, viscosity, and free formaldehyde content were evaluated to gauge its application performance.

This work introduces a new method to analyze cavitation in industrial-grade rubbers based on ultra small-angle x-ray scattering. This method employs a specially designed multi-sample stretching device for high-throughput measurements with statistical relevance. The proposed data reduction approach allows for early detection and quantification of cavitation while providing at the same time information on the hierarchical filler structures at length scales ranging from the primary particle size to large silica agglomerates over four orders of magnitude. To validate the method, the scattering of SSBR rubber compounds filled with highly dispersible silica at different ratios was measured under quasi-static strain. The strain was applied in incremental steps up to a maximum achievable elongation or breakage of the sample. From the measurements performed in multiple repetitions, it was found that the minimum strain necessary for cavity formation and the size evolution of the cavities with increasing strain are comparable between these samples. The sample with the highest polymer content showed the lowest rate of cavity formation and higher durability of silica structures.

Among these techniques, encapsulating biologically active substances in polymeric nanoparticles has garnered significant attention. However, achieving high encapsulation efficiency for hydrophilic molecules remains a formidable challenge, despite their growing importance in treating diverse diseases such as cancer, where nucleic acids, peptides, proteins, and smaller hydrophilic molecules are key players. While some studies have reported improvements in encapsulating hydrophilic drugs, notable examples, like the solid/oil/water ion-pairing method and the use of calcium phosphate, have shown promise in enhancing encapsulation efficiency for different drugs. Nonetheless, the challenge of preparing aqueous core nanoparticles capable of encapsulating a high percentage of water-soluble actives persists. Creatine monohydrate, a bioactive compound widely consumed by athletes for its role in increasing muscular phosphocreatine stores, presents an intriguing case. Despite its insolubility in organic media, creatine exhibits limited aqueous solubility, rendering it a suitable candidate for encapsulation in polymeric nanoparticles to improve its aqueous solubility and gastrointestinal absorption. In this study, we aim to produce polymeric nanoparticles containing creatine monohydrate utilizing the double emulsification (W/O/W) method. This promising and efficient approach holds the potential to significantly enhance the aqueous solubility and gastrointestinal absorption of creatine, thereby broadening its clinical application spectrum.
