Summary: A versatile method for the creation of multitier hierarchical structured surfaces is reported, which optimizes both antiviral and hydrophobic properties. This methodology has significant advantages, such as overcoming the droplet-pinning effect, delivering surfaces with high contact angles and good antiviral efficacy, and creating mechanically robust, nanostructured surfaces using nonspecialized equipment.

Summary: The self-cleaning mechanism of hydrophobic surfaces, also known as the lotus effect, has attracted much attention in various industries. This effect relies on the roughness and surface chemistry of the hydrophobic surfaces to create high contact angles, causing water droplets to roll off the surface and carry away dirt. Understanding and applying phyto-based hydrophobic surfaces can have significant ecological and physiological implications.

Summary: In this work, a series of super-hydrophobic surfaces were fabricated by spraying a layer of hydrophobic nano particles on sandpapers with micro-scale abrasive particles. The coated sandpapers with grit sizes of 240, 400, 800, 1000, and 1500 exhibited high water contact angles and low sliding angles, indicating super-hydrophobicity. The robustness of the super-hydrophobic sandpapers was attributed to the hierarchical roughness structures.

Summary: In this study, super-hydrophobic Al2024 sample surfaces were achieved using a nanosecond pulsed fiber laser. It was found that the fresh laser-treated aluminum alloy surfaces were super-hydrophilic, but the contact angles increased over time. The lotus effect was obtained at various time scales, with contact angles exceeding 150 degrees and sliding angles less than 10 degrees. The wettability transition from hydrophilic to super-hydrophobicity (lotus) was attributed to the Al-C bond.

It was found that PEG-6000 and PSS polyelectrolytes promoted the formation of spherical vaterite calcium carbonate particles. Additionally, silver nanoparticles were loaded into the PCC particles, increasing their surface area and potential applications in antimicrobial food packaging or wound dressing.

Summary: The loss of spontaneous liquid repellency on the surface of AISI 304 stainless steel under UV irradiation has been studied using femtosecond laser pulses to create different textures. It was found that laser-induced periodic surface structures (LIPSS) show lower liquid repellency compared to microgrooves. The polarity of the super-hydrophobic non-polar layer increased to a super-hydrophilic state under UV irradiation. The rate of this transition is influenced by the surface topography and is faster for LIPSS compared to bihierarchical textures formed by LIPSS and microgrooves.

Summary: This study aims to achieve the high-value application of calcium during seawater decalcification. Aragonite or vaterite with a high purity exceeding 99% was successfully synthesized using synthetic seawater as a calcium source and Na2CO3/NaHCO3 solution as the carbonate supplier. The effects of coexisting ions in synthetic seawater on crystal polymorph and crystallization kinetics were systematically investigated, and it was found that the presence of Mg2+, K+ or SO42- favored the precipitation of aragonite while Mg-free synthetic seawater favored the formation of vaterite. Additionally, hydrophobic spherical vaterite particles were prepared by in-situ surface modification using alka-nolamide 6502 as a surfactant, demonstrating a promising approach to enhance the utilization of calcium during the seawater decalcification process.

Summary: A thin liquid film method is proposed to evaluate sand erosion in annular flow. This method considers the direct interaction between the liquid film and gas core, as well as the entrainment and deposition of droplets. The erosion rate is calculated by considering the effects of liquid entrainment and particle velocity decay. The method is fully verified by comparing with experimental data.

Summary: A new micro/mini-channel heat sink (MCHS) with a combined structure of longitudinal and transverse vortex generators is designed, using Al2O3 nanofluid as the working medium. The study explores the effects of transverse vortex generator shape and longitudinal vortex generator angle on the hydraulic and thermal characteristics, comprehensive performance, entropy generation, and exergy efficiency. The results show that the triangular transverse vortex generator improves the comprehensive performance and exergy efficiency. Combined with the longitudinal vortex generator, the MCHS achieves the best comprehensive performance, entropy generation, and exergy efficiency when the Reynolds number is 742.

Summary: Gas-solid fluidized-bed systems have advantages in terms of chemical reaction efficiency and temperature control, making them widely used in industrial applications. However, the design, scale-up, and optimization of these complex units are limited by the lack of deep physical understanding. Non-invasive and non-intrusive diagnostic techniques provide a way for researchers to study these systems without affecting the flow field or directly contacting the medium under study.

Summary: In this study, a numerical model of sand triaxial test was established using discrete element software PFC3D, and an indoor triaxial test was conducted to calibrate the numerical model. The influence of microscopic parameters on the macroscopic mechanical response of sand was analyzed. The results showed that the friction coefficient had the greatest impact on the peak strength and residual strength of the sand's stress-strain curve, and it was positively correlated. The normal tangential stiffness ratio was negatively correlated, while the porosity and boundary flexibility stiffness had minimal influence on it.

Summary: Fluidization at low pressure offers significant benefits for the fine chemical industry. This study investigates the behavior of bubbles and bed expansion under low pressure conditions. It is found that lower pressure leads to larger bubbles, increased bubble quantity, and higher aspect ratio. The predictability is affected by the inhomogeneous fluidization, but low pressure fluidization can generate similar bubble sizes with lower fluidizing mass compared to atmospheric pressure.
