Based on preliminary investigations, this study proposes a composite system utilizing a cationic surfactant combined with a nonionic surfactant. Specifically designed for post-CMP cleaning of Co patterned wafers, the system addresses the issues of low particle removal efficiency (PRE) associated with single surfactant approaches. The cleaning performance of this system was validated for the first time on actual Co patterned wafers (94.58 % PRE), which is significantly superior to that of individual surfactant systems. Contact angle measurements demonstrate that the introduction of composite surfactants enhances the wettability of the cleaning solution, mitigating the hydrophobicity of the Co surface induced by corrosion inhibitors. Furthermore, zeta potential measurements and analysis of electrostatic interactions indicate that under the influence of the complex surfactant, stronger repulsion occurs between silica particles and the Co surface, facilitating effective particle cleaning. Quantum chemical calculations further elucidate the efficacy of surfactants, with hydrophilic groups serving as primary adsorption sites.

In this work, molecular dynamics (MD) simulations are used to investigate the flow behavior of multi-component oil and water within shale nanopores. Compared with alkanes, active component (n-decylamine) and heavy component (asphaltene) show preferential adsorption to the water layer at the oil-water interface, primarily driven by electrostatic interactions. Interestingly, this phenomenon significantly weakens the liquid-liquid slip at the oil-water interface and reduces the flow velocities. It also demonstrates that increasing the pressure gradient promotes desorption of n-decylamine and asphaltenes from the oil-water interface into the pure oil phase. Differences in interaction energy with the water layer lead to a relatively greater desorption of asphaltenes.

Similar to macromolecular ICIs, the efficacy of BMS is also limited by the immunosuppressive tumor microenvironment (TME). Paclitaxel (PTX), a classic anti-tumor drug, not only exerts direct cytotoxic effects but also induces immunogenic cell death (ICD), thereby remodeling the TME and potentially enhancing the efficacy of ICIs.

In vivo, this nanoparticle system demonstrated highly efficient accumulation in esophageal tumor tissues. Within the tumor microenvironment, PTX-triggered ICD and BMS-mediated blockade of PD-1/PD-L1 interaction work synergistically to reverse immunosuppression, thereby reactivating and restoring T cell function.
