Summary: The aim of this study was to investigate the stability and morphology of polystyrene latex with kaolinite as a filler during the synthesis of nanocomposites through emulsion polymerization. Nanocomposites with different weight percentages of kaolinite (1%, 3%, and 5%) were prepared. Latexes with 1% to 3% kaolinite showed stability during the polymerization reaction, and the hydrodynamic diameters were measured to be 93.68 nm and 82.11 nm for the latexes with 1% and 3% kaolinite, respectively. XRD, SEM, and HRTEM analysis confirmed the presence of exfoliated and intercalated structures of kaolinite.

Summary: In this study, a direct approach for the fabrication of noncovalent raspberry-shaped microgels was developed. This approach utilizes electrostatically driven heterocoagulation of binary microgels with complementary functional groups at the oil-water interface. The results show that the addition of hexanoic acid improves the hydrophobicity and interfacial activity of microgels, and raspberry-shaped microgels achieve high coverage on the droplet surface, resulting in an elastic interface and excellent stability of emulsions.

Summary: Cellulose nanocrystals (CNCs) with different surface properties were incorporated into emulsion-based pressure-sensitive adhesives (PSAs) to modify their properties. CNCs with higher hydrophilicity and surface charge showed less association with latex particles and resulted in nanocomposites with lower strain-softening behavior and improved PSA properties.

Summary: Hybrid latex particles, which combine inorganic nano/micro particles with polymers, have shown great potential for various applications. In recent years, there has been increased interest in designing and preparing hybrid latex particles with well-defined size, structure, and morphology. In situ (Pickering) emulsion polymerization has been proven to be a powerful method for large-scale preparation of hybrid latex particles due to its simplicity, versatility, and environmental friendliness. This review systematically summarizes the strategies and applications of in situ (Pickering) emulsion polymerization for the preparation of hybrid latex particles, with a focus on enhancing properties and achieving well-defined morphologies such as core-shell, yolk-shell, multinuclear, raspberry-like, dumbbell-shaped, multipod-like, or armored structures. The presented advances, examples, and principles in this review aim to inspire further research on current preparation technologies, development of new processes, and exploration of hybrid latex particles with outstanding characteristics and properties.

Summary: In this study, a new and facile method for preparing CNC/polymer nanocomposite latices via surfactant-free emulsion polymerization was reported. The distribution of CNCs in the latex particles could be controlled by adjusting the reaction procedures, resulting in improved mechanical properties of the nanocomposite latices. Unlike typical Pickering emulsion polymerization, this process does not require intense mechanical shearing and offers a scalable approach for preparing stable CNC/polymer nanocomposite latices that can be used in various applications.

Summary: In this study, aqueous miniemulsion polymerization based on Activators regenerated by electron transfer (ARGET) atom transfer radical polymerization (ATRP) was used to investigate the effects of hydrophobicity of monomers on dispersity, molecular weight, and particle stability. The results showed that monomers with higher hydrophobicity exhibited narrower dispersity and better control, while monomers with higher hydrophilicity led to reduced emulsion stability. This research provides insights into controlled polymerizations of hydrophilic monomers using ARGET-ATRP in miniemulsion conditions, with implications for synthesis of polymer-grafted nanoparticles with hydrophilic corona.

Summary: The vibrational eigenmodes of dumbbell-shaped polystyrene nanoparticles were studied using Brillouin light spectroscopy. The experimental spectra were recorded and theoretically calculated. Unlike spherical particles, the eigenmodes of dumbbells exhibit either single or double degeneracy due to their axial symmetry. A new low-frequency peak observed in the BLS spectrum was attributed to the out-of-phase vibration of the two lobes. The quantization of acoustic modes in these molecule-shaped dumbbell particles changes as the separation between the lobes increases.

Summary: The study investigates the influence of electrostatic interactions on the dynamical response in dispersions of magnetic nanoplatelets, and finds that tuning the interactions with an ionic surfactant leads to new dynamic modes in magnetic response spectra. The collective modes can be induced or suppressed by varying the concentration ratio of the nanoplatelets to the surfactant or increasing the nanoplatelet concentration, reflecting the nanoscale characteristics of this fluid magnet.

Summary: This study investigates the effect of a photovoltaic field generated on the irondoped lithium niobate crystals surface on droplets of a ferroelectric nematic liquid crystal and a standard nematic liquid crystal material present on the surface. When illuminated with a laser beam, a wide range of dynamic phenomena occur, including the dragging of droplets outside the laser spot towards the illuminated area and the rearrangement and bridging of droplets in the illuminated region. The behavior of the droplets differs between the ferroelectric nematic phase and the nematic phase, attributed to the difference in dielectric permittivity between the two phases.

The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.

The encapsulation efficiency of major components of essential oil was determined, and it was found that they followed Higuchi model of release kinetics. The essential oil loaded nanostructured lipid carrier showed significantly higher mycelial growth inhibition compared to pure essential oil, indicating enhanced bio-efficacy.
