Summary: Microwave-induced in situ amorphization is a novel technology for preparing amorphous solid dispersions (ASDs). This study investigated the feasibility of using non-ionic surfactants as plasticizers to facilitate microwave-induced in situ amorphization. It was found that surfactants with low melting point, low molecular weight, and high HLB were successful in promoting amorphization. Kolliphor RH40 was selected as a typical surfactant due to its excellent dielectric heating ability, plasticizing effect, and solubilizing effect. The dissolution-mediated in situ amorphization mechanism was also investigated and demonstrated.

Summary: In this study, the dispersion ability of six representative surfactants for carbon nanotubes (CNTs) was compared using molecular dynamics simulations and experimental investigations. Triton X-100 and sodium dodecyl benzenesulfonate (SDBS) showed the strongest interaction with CNTs, while sodium dodecyl sulfate (SDS) showed the weakest interaction. Structural factors such as the presence of benzene rings and long alkyl chains were found to enhance the adsorption efficiency of surfactants on the CNTs surface. This study provides guidance for selecting optimal surfactants for CNTs dispersion.

Summary: Frequency-modulated (FM) laser combs, generated through spatial hole burning, group velocity dispersion, Kerr nonlinearity, and four-wave mixing (FWM), have applications in wavelength-division multiplexing, precision metrology, and ultrafast optical ranging. In this study, a 60 GHz quantum-dot (QD) modelocked laser capable of generating both amplitude-modulated (AM) and FM combs was developed. The Kerr nonlinearity was engineered to improve FM comb bandwidth without the need for group velocity dispersion (GVD) engineering. The QD platform demonstrated a maximum 3-dB bandwidth of 2.2 THz, paving the way for energy-efficient frequency combs in silicon photonic integrated circuits (PICs).

Summary: The study investigated the interaction of two anionic dyes with cationic and mixed-surfactant media using UV-Visible spectroscopy. It was found that the solubilization of dyes was enhanced by mixing nonionic/cationic surfactants, and the dye-surfactant aggregates were stable in the media. The synergistic effect of cationic surfactant with nonionic counterpart led to deep entrapment of dye molecules in the micelles.

Summary: There is a growing need to understand the relationship between construction material properties and behavior with their microstructure, especially in the context of freshly poured cement-based materials. This study focuses on developing a reliable method for monitoring the hydration process in cementitious composites enhanced with carbon nanotubes, utilizing a combination of nonlinear elastic waves, contact ultrasonics, and noncontact optical detection. Changes in material nonlinearity during the hardening process, particularly with increased carbon nanotube concentration, can be detected through the assessment of higher-harmonic amplitudes of an ultrasonic wave, providing valuable insights for structural behavior in the long term.

Summary: Novel aluminium matrix composites reinforced by MoTaNbVW refractory high-entropy alloy (HEA) particulates were fabricated by powder metallurgy. The composites exhibited low porosity, good homogeneity, few defects, and good distribution of the reinforcing phase in the Al matrix. However, increasing the volume of the reinforcing phase led to increased hardness values, while the Al-HEA composites showed susceptibility to localised forms of corrosion in 3.5% NaCl solution.

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.
