Summary: Hierarchical assemblies of a new silver nanocluster, Ag-70-TPP, have been synthesized and characterized, showing a highly space-efficient double helical 4H close packing pattern directed by ligands. The chirality of Ag-70-TPP and van der Waals forces interactions between ligands play a key role in driving its arrangement, with observed interlocking of phosphine ligands contributing to the structure. This work provides important and unprecedented insights into the internal structure and crystallographic arrangement of nanoclusters.

Summary: The study evaluated the deodorant activity of black cumin seed against organosulfur compounds related to garlic odor, finding that black cumin seed essential oil showed remarkable deodorant activity against garlic essential oil, presumably by covalently reacting with the sulfur compounds. This reaction, particularly with thymoquinone and allyl mercaptan, was identified as a key factor in the deodorizing effect.

Summary: The effect of inorganic nanoparticles on the structure of hybrid block copolymer particles and the local distribution of nanoparticles is studied. The study focuses on comparing the nanoparticles made of Au and Fe3O4. The distribution of nanoparticles inside the particles was found to affect the overall particle morphology. Au nanoparticles were selectively localized inside certain domains regardless of the particle morphology, while Fe3O4 nanoparticles clustered and segregated to the interfaces of the particles.

Summary: The study investigated the ability of isoelectrically precipitated chickpea protein isolate (CPI) and its combination with maltodextrin (MD) to form and stabilize cumin seed oil microcapsules, as well as the creaming stability of CPI at different pH levels. The optimized conditions for minimal cream separation were found to be 0.19% CPI and 6.83% oil concentrations. Spray drying was used to microencapsulate cumin seed essential oil within the CPI-MD matrix, and the effects of CPI-MD matrix formulation on the physicochemical characteristics and volatile composition of the microcapsules were examined. The results showed that the CPI-MD matrices had positive effects on properties such as lower surface oil, higher encapsulation efficiency (EE), and oil retention.

Summary: Ionic liquids (ILs) are a class of chemicals with controllable properties through modification of their chemical structure. This study developed a predictive model for the dielectric constant of ILs using the linear free-energy relationship equation. The research revealed that the structure of cations has a greater influence on the dielectric constant, and the H-bonding acidity of cations and basicity of anions, as well as the dipolarity/polarizability of cations and anions, are important factors in the prediction.
