Summary: This study investigates the dynamic behavior of four industrial granular materials - wheat flour, sericite, microcrystalline cellulose, and glass beads - when subjected to vertical vibration using a particle damper. The effect of the vibration wave is studied by varying two dimensionless parameters: the relative acceleration C and relative frequency X, including the relaxation time between periods. The results show that despite the cohesiveness of the samples, their compaction dynamics occur in at least two compaction steps that can be modeled using a succession of stretched exponentials, denoted as a generalized KWW model.

Summary: The desire to optimize the production and performance of nanoparticle structured materials has driven the development of increasingly accurate and fundamental models, presenting challenging multiscale modeling problems. Particle assemblies at nanoscale form complex aggregates and agglomerates, requiring new contact models at the primary particle level. Ambient conditions such as humidity have a significant effect on the final structure of materials due to capillary and solvation forces.

Summary: The recycling and reutilization of powdery/dust waste are increasingly important for a sustainable environment and cost reduction. This study investigates component separation using a vibrating fluidized bed and the effects of particle properties on agglomerate formation and destruction. Test powders of rutile and anatase titanium oxide and zinc oxide were used, and changes in the powder layer height and pressure drop were observed. The Ergun equation was utilized to compute agglomerate size and evaluate formation and destruction, and the relationship between equilibrium agglomerate size and vibration intensity was examined.

Summary: This study investigates the interaction between infrared laser and aerosol Pt and Ag nanoparticle agglomerates. The results show that under specific conditions, the agglomerates can be transformed into individual spherical nanoparticles. The required energy density for this transformation varies with the size distribution and extinction of the agglomerates.

Summary: In this study, the stability of nonionic surfactant-stabilized foam was improved by using a series of Janus nanoparticles. The researchers found that the PMIE-JS3 system exhibited extraordinary foamability and stabilizing ability at a low concentration. Furthermore, they explored the mechanism behind the foam stability and demonstrated that the PMIE-JS3-stabilized foam remained stable even in the presence of crude oil. Sandpack flooding tests confirmed the effectiveness of the PMIE-JS3-stabilized foam in enhancing oil recovery.

Summary: This study aimed to investigate the effects of hypertension on silica nanoparticles (SiNPs) induced hemolysis and the underlying pathophysiological mechanism. SiNPs caused dose-dependent hemolysis, erythrocyte deformity, and increased susceptibility to lipid peroxidation. The concentration of intracellular Ca2+, annexin V, and calpain activity were also increased by SiNPs. Importantly, all these effects were potentiated in erythrocytes from hypertensive rats.

Summary: The study examined the rapid aggregation of single-domain magnetic iron oxide nanoparticles in stable aqueous colloidal suspensions under the influence of a radio-frequency (RF) magnetic field. It was found that the RF field caused localized heating, leading to the destabilization of the colloid and faster agglomeration of nanoparticles. These findings have implications for biomedical applications and wastewater treatment.

Summary: A simple fluorescence-based lateral flow test platform was developed for rapid screening of influenza B virus. The system utilizes Cy5-loaded silica nanoparticles directly conjugated to monoclonal antibodies for detection, showing good sensitivity and specificity under optimized conditions. Detection can be performed within 30 minutes with small sample volumes, and the system demonstrates no cross-reactivity to other closely related respiratory viruses.
