Summary: In recent decades, microbubble flotation has been extensively researched for fine mineral separation and beneficiation. It offers advantages over conventional flotation, such as high grade and recovery and low reagent consumption. This review summarizes the latest advances in microbubble flotation for fine mineral particles. Microbubbles possess small bubble size, large specific surface area, high surface energy, and selectivity, allowing them to easily attach to hydrophobic particles or large bubbles, reducing the probability of particle detachment. Various methods, such as pressurized aeration, electrolysis, ultrasonic cavitation, and photocatalysis, can be used to generate microbubbles. Fine-particle flotation equipment includes microbubble release flotation machines, centrifugal flotation columns, packed flotation columns, and magnetic flotation machines. Microbubble flotation has shown superiority in the beneficiation of ultrafine coals, metallic minerals, and nonmetallic minerals. Mechanisms supporting the promotion of fine-particle flotation by nanobubbles include particle agglomeration, nanobubble stability in aqueous solutions, and enhancement of particle hydrophobicity and flotation dynamics.

Summary: This study reports a controllable underwater gas bubble (UGB) transport method on a surface using a magnetism-actuated robot (MAR) and biomimetic laser-ablated lubricant-impregnated slippery surfaces (LA-LISS). By leveraging the MAR and LA-LISS, UGBs can be moved along arbitrary directions and controlled using a tracing magnetic trigger. Experimental results show that UGBs can achieve ultrafast velocities on optimized LA-LISS, and the MAR can steer UGBs on inclined surfaces. Additionally, the MAR can be used for configuring UGB patterns, achieving on-demand coalescence, repairing cutoff switches, and facilitating programmable light-control-light optical shutters.

Summary: Particle Image Velocimetry (PIV) estimates velocities through particle image correlations, which leads to a modulation effect. To exploit the scattered data from Particle Tracking Velocimetry (PTV), interpolation on a structured grid is necessary, causing spatial modulation bias. A technique called Ensemble Particle Tracking Velocimetry (EPTV) is introduced to reduce this systematic error by merging different instantaneous realizations and obtaining high-resolution mean flow. The methodology is validated against various datasets with increasing complexity, using PTV and PIV analysis.

Summary: This paper presents a method for simultaneous particle image velocimetry (PIV) on parallel planes offset in depth. The method uses image splitting optics with variable optical path lengths to place images from two planes onto different halves of a camera sensor. It achieves a shallow depth of field to ensure that only one plane is in focus on each half of the sensor. The method is designed as an inexpensive means to increase the number of measurement planes in PIV setups and can be combined with existing plane discrimination approaches.

Summary: This paper proposes a novel streak-resolving algorithm for particle streak velocimetry (PSV) to resolve velocity fields for a single image frame with multiple particle streaks. The algorithm reconstructs the streak information and particle trajectory by approximating a model streak function using a multivariable least-square fit procedure. The accuracy of the algorithm is evaluated through performance tests with synthetic streaks and experimental streak images. The results demonstrate the effectiveness of the proposed algorithm in resolving velocity fields with high accuracy and low error.

Summary: This study established a micro-scale observation system to investigate the interaction between flocs and bubbles in the separation zone of the dissolved air flotation process. It was found that small flocs have a higher unit buoyancy and collision probability with bubbles, enabling them to capture bubbles and accumulate enough buoyancy for efficient flotation separation in a short time. The simulation and practical verification both support the favorable role of small flocs in achieving high separation efficiency in the flotation process.

Summary: This study focuses on the fouling of forward osmosis (FO) membranes by microplastics (MPs) of different sizes, and the interactional impacts of MPs and humic acid (HA) on FO membrane performance. The presence of MPs and HA together causes a higher decline in flux for FO membranes than when either HA or MPs are present alone. The reverse salt flux increases in the presence of MPs and decreases when HA is present. All fouled membranes recover their full flux after hydraulic cleaning, indicating the efficiency of FO systems for treating wastewater with high fouling potential. This study highlights the necessity of considering MPs in studying fouling behavior and mitigation strategies for membranes used in wastewater treatment.

Summary: With the increase of microplastics in water and wastewater, it is necessary to study their removal using tertiary treatment systems to minimize and prevent their entrance into aquatic environments. Forward osmosis is a membrane process that shows potential in removing microplastics from wastewater, but it requires high-performance membranes with low fouling tendency. This study focuses on modifying thin film composite FO membranes with a water-stable and hydrophilic metal-organic framework, which shows improved antifouling properties against microplastics and organic foulants.

Summary: The storage of thermal energy from solar intensity is crucial for improving the efficiency of desalination systems during nighttime when solar intensity is not available. While solar energy has the potential to address the freshwater needs of small communities, the productivity of freshwater generation using solar stills is relatively low compared to other desalination methods. This comprehensive review explores multiple innovative materials, including nanomaterials, nanofluids, and phase change materials, that have been investigated to enhance water production by solar stills. The findings highlight the significant influence of advanced energy storage materials on improving solar still productivity, with thermosyphon heat pipes and PCM-based materials doubling and increasing water productivity by 40-70%, respectively. The review also includes a cost analysis and environmental evaluation of PCM-based solar desalination, and provides recommendations for further research in efficient water treatment methods.

Summary: Temperature polarisation (TP) is a major drawback for membrane distillation (MD) technology. The conventional Temperature Polarisation Coefficient (TPC) is an ineffective tool to study TP along the membrane. This research measures the temperature profile along a lengthy DCMD membrane and explores its impact on TP. The results show that TP is not constant along the membrane and the temperature profile is asymmetric due to the effects of inlet and outlet on flow.

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.
