Summary: Wormlike micelles (WLMs) are important components in many consumer products and industrial fluids due to their shear-dependent viscous texture. The alignment of the worms in the shear field plays a crucial role in their behavior during shear, leading to rapid ordering loss when shear stops. However, most studies on these systems have been limited to dilute solutions, and analyzing shear-induced many-body effects in high volume fraction dispersions has proven to be complex. In this study, the shear alignment of concentrated WLM solutions was explored, and it was found that these concentrated worms can be approximated as cylinders that align more with the shear direction as volume fraction and shear rate increase.

Summary: Nuclear waste repository designs require backfill materials capable of immobilizing contaminants, including high mobility pertechnetate (TcO4-). Bentonite backfill can be functionalized with organic or inorganic species to optimize the clay's retention capacity for TcO4-. The current work examines the physicochemical properties of organoclays that were functionalized with alkylammonium cations of different sizes and iron. The organoclays were characterized, and the physicochemical characteristics were correlated with the extent of TcO4- removal. The results show that the clay zeta potential and carbon content are valuable indicators for predicting the organoclay's ability to sequester TcO4- from aqueous solution. Furthermore, the Fe functionalization improves TcO4- removal.

Summary: Due to the potential bioaccumulation and toxicity of PFOS, PFOA, and their derivatives, people have tried to substitute legacy fluorosurfactants with short-chain alternatives. While short-chain alternatives can reduce bioaccumulation, their surface activity is compromised. In this study, a series of fluoroether betaine surfactants were prepared and investigated for their surface activity and spreading property. The role of oxygen in surface activity was discussed, and it was found that the insertion of oxygen atoms into the fluorinated chain can increase hydrophobicity and enhance surface activity. The inclusion of oxygen also diversified the structure to bridge the gap in surface activity between short and long fluorosurfactants. Overall, this work provides fundamental knowledge for molecular design.

Summary: This research investigated the influence of shape and size of plastic waste on the properties of geopolymer mortars. The study found that smaller plastic aggregates improved the flowability and mechanical properties of the geopolymer mortars. However, the presence of PET particles resulted in lower compressive strength and splitting tensile strength due to poor interaction with the matrix. Enhancing the adhesion between PET particles and geopolymer mortars could potentially address this issue.

Summary: This work explores the recycling potential of PET bottle wastes as a substitute for natural sand in GP mixtures, aiming to reduce plastic pollution and promote a circular economy. The study finds that increasing the content of plastic aggregates in GP mortars leads to a decrease in compressive and flexural strength, but replacing a certain volume of sand with plastic aggregates can improve the splitting tensile strength and workability of fresh geopolymer mixes. Additionally, the inclusion of recycled PET bottle wastes in GP mortars offers advantages in lightweight, water absorption, and thermal insulation properties, contributing to the production of sustainable construction materials with environmental and economic benefits.

Summary: This study provides data on the IR spectra of kaolinite at different moisture levels and explores the interaction between liquid water and the sorbing basal surfaces of kaolinite. The results suggest that the adsorption effect is weaker than the solvation effect, and it decreases with increasing salinity. The study also observes an increase in peak intensities during the drying process. These findings are valuable for testing theoretical models and computer simulations of moist minerals and salt adsorption mechanisms.

Summary: The complexes of He, Ne, Ar, Kr, and Xe with B3N3H6 were investigated using MP2, CCSD(T), and SAPT ab initio methods. The complexes can be described as mono-, di-, and tri-coordinated to the N atoms, with stability following the order N-mono < N-di < N-tri. The interactions are dominated by dispersion and the binding energies are within the range of 1 or 2 kcal mol(-1). The results were compared with a recent DFT study on larger BN sheets complexes [Phys. Chem. Chem. Phys. 24 (2022) 2554-2566.].

Summary: It has been found that the introduction of buffer layers improves the electrical performance of solid oxide fuel cells (SSOFCs). In this study, varying ratios of Gd-doped CeO2 were used as buffer layers in YSZ-based SSOFCs. The results demonstrate that the performance of SSOFCs is enhanced when a buffer layer is added, with the highest performance achieved using Ce0.8Gd0.2O2-delta (GDC20) as the buffer layer. This suggests that the use of GDC series buffer layers is an attractive strategy to optimize performance loss due to electrolyte-electrode interactions.

Summary: This study investigates the influence of aspect ratio and quantum confinement on the single-photon and two-photon absorption cross-section of perovskite CsPbI3 nanorods. Experimental data shows that CsPbI3 nanorods have an extremely high two-photon absorption cross-section, significantly surpassing organic chromophores and other CsPbBr3 nanocrystals. Moreover, adjusting the aspect ratio can significantly enhance the absorption ability. Additionally, the study also reveals a moderate quantum confinement effect on the single-photon and two-photon absorption cross-section of the nanorods.
