Solvent flotation primarily relies on the variations in the activity of substances to adsorb target compounds onto the surface of bubbles, thereby facilitating the process of separation and extraction. This technology has the advantages of high separation efficiency, gentle process, and simple operation, making it widely applicable across various fields. This article reviews relevant research from the past decade to analyze the factors influencing this technology. Additionally, it provides a comprehensive overview of its applications in detecting organic matter in environmental samples and extracting bioactive compounds from natural products, while also anticipating upcoming trends in its development.

Inspired by the remarkable buoyancy and collective adaptability of fire ant rafts, this study presents magnetic composite micro-floaters (MCMs) capable of stable flotation at air-water interfaces-a key advancement for magnetic microrobotic swarms in fluid environments. The system overcomes the intrinsic sinking tendency of high-density NdFeB microparticles through bioinspired surface engineering. MCMS are fabricated via a solvent-exchange phase inversion process, encapsulating NdFeB cores with hydrophobic polycaprolactone (PCL) and engineered surface roughness.

Peptic ulcers, caused by factors like infection and NSAID overuse, are often treated with drugs that can have significant downsides. Curcumin, a natural compound with high therapeutic potential, faces challenges due to poor solubility and instability. Innovative delivery systems are key to unlocking curcumin's full benefits for effective peptic ulcer treatment.

In the wake of global energy transition and the "dual-carbon" goal, the rapid growth of electric vehicles has posed challenges for large-scale lithium-ion battery decommissioning. Retired batteries exhibit dual attributes of strategic resources (cobalt/lithium concentrations several times higher than natural ores) and environmental risks (heavy metal pollution, electrolyte toxicity). This paper systematically reviews pyrometallurgical and hydrometallurgical recovery technologies, identifying bottlenecks: high energy/lithium loss in pyrometallurgy, and corrosion/cost/solvent regeneration issues in hydrometallurgy.

Froth flotation effectively separates anode graphite from cathode active materials (CAMs) of spent lithium-ion batteries when CAM particles are free of organic binders, such as polyvinylidene fluoride (PVDF). This study investigated a bio-based solvent, dihydrolevoglucosenone (Cyrene ), as a pretreatment to remove the PVDF binder from both single chemistry black mass (BM) and industrially produced mixed chemistry black mass (IBM). The subsequent flotation combined with high-intensity attritioning improved CAMs and graphite separation efficiency compared to that of mechanical pretreatment alone, increasing from 0.

The rapid advancement of electric vehicles imposes significant challenges on lithium-ion battery (LIBs) technology. Polymer binders offer a promising low-cost solution. However, for anode materials, the conventional styrene butadiene latex/carboxymethyl cellulose (SBR/CMC) binders exhibit inherent issues, including binder flotation during solvent evaporation and undesired film formation on anode surfaces.
