Summary: This study investigated the effect of particle size distribution of quartz sand conditioners on sludge dewatering performance. The results showed that the particle size distribution significantly influenced the efficiency of sludge dewatering. By changing the particle size distribution, the conditioners improved the dewatering channels and pore structure of the sludge.

Summary: This study investigates the effects of shape and particle size on the kinetics of adsorption and photocatalysis of nano-CeO2 materials. The results show that shape and particle size have significant influences on the performance of adsorption and photocatalysis. However, they have no effects on the kinetics and mechanism of the overall photocatalytic process. A generalized mechanism and rate equation for the photocatalytic kinetics of nanomaterials are proposed.

Summary: Microwave irradiation has the potential to be used for rock fracturing. Understanding the microwave cracking characteristics and mechanism of action of ores is significant for the application of microwave technology in metal mines. Through investigating different morphologies and particle sizes of copper, iron, and gold ores, the microwave cracking characteristics and mechanism of action of ores were revealed based on their dielectric properties and arc characteristics. The results show that the morphology of the ore affects its microwave cracking characteristics.

Summary: The ongoing COVID-19 outbreak has brought personal protective equipment, especially facemasks, into the spotlight. Despite high vaccination rates in some countries, breakthrough infections have prompted the re-recommendation of facemask usage. Filtering facepieces (FFP) offer better protection efficiency than surgical and community masks, although improper fitting may reduce their effectiveness.

Summary: This paper introduces a hierarchically-arranged multilayer isoporous air filter, consisting of an ultrathin nanoporous active filtration layer and a microporous support layer. By designing and fabricating microscale spacer structures, a gap was created between the nanoporous and microporous membranes, maximizing airflow and reducing pressure drop across the membrane.

Summary: This study investigated the physicochemical properties of dry- and wet-milled LLZTO particles and found that dry-milled LLZTO powder exhibited higher reactivity and better particle characteristics, resulting in higher room temperature ionic conductivity. The sintered LLZTO ceramic pellets prepared from these dry-milled powders showed excellent discharge performance in lithium-sulfur batteries.

Summary: In this study, the influence of sonication on the reactive precipitation of ammonium uranyl carbonate (AUC) was investigated. It was found that sonication increases precipitation kinetics, modifies crystal morphology, decreases particle size, and produces powders with more surface area. Sonication also leads to more uniform and regular crystals compared to silent conditions, and results in a more crystalline powder of AUC. This sonochemical technique shows improved quality of AUC precipitates in terms of physical morphology, surface area, crystallinity, and homogeneity.

Summary: The desorption kinetic parameters and surface acidity of nano-SnO2 with different shapes and sizes for NH3 were measured, showing that shape and size have significant influences on these properties. The influence mechanism is attributed to the effect of shape and particle size on the surface acidity of nano-SnO2.

Summary: The tribological behavior and airborne particle emissions of copper metal matrix composites (Cu-MMCs) were studied under different sizes of CrFe particles. The results showed that the size of CrFe particles greatly influenced the frictional properties, particle emission behavior, and worn surface characteristics of Cu-MMCs. Cu-MMCs with medium-sized CrFe particles produced the highest levels of particle emissions, followed by Cu-MMCs with large-sized particles, and then Cu-MMCs with small-sized particles. The level of particle emissions increased significantly with increasing sliding speed.

Summary: Mesoporous silica microspheres (MPSMs) were synthesized using a hard template method to control particle size and pore properties. Response surface methodology was applied to predict the effects of synthesis parameters on MPSM characteristics. The prepared MPSMs were successfully applied as stationary phase for reversed-phases liquid chromatography, achieving protein and amino acid separation.

Summary: Surface patterning on filtration membranes provides benefits of increasing effective filtration area and enhancing back diffusion of foulants. This study investigates the relationship between pattern sizes and foulant particle sizes, and finds that the performance of ceramic membranes with different topographies varies in fouling alleviation. The best design for fouling alleviation is a combination of h = 120 μm and s = 500 μm.
