Antigravity confined interfacial self-assembly approach for the synthesis and characterization of nanofilms
Gravitationally induced stratification during self-assembly often leads to density-driven vertical segregation, resulting in an inherent density gradient that severely limits the synthesis of metastable nanofilms requiring inverted architectures. Here we show an antigravity confined interfacial self-assembly approach based on a liquid-liquid interface formed between hydrophilic and hydrophobic porous membranes, where capillary forces suppress gravitational effects to enable precise molecular organization.

Green Enhanced Oil Recovery (EOR)
The stable, adaptable nanofilms are highly promising for EOR, overcoming challenges like water breakthrough in porous media. They improve displacement efficiency and offer a biocompatible alternative to synthetic agents.
Revolutionizing Oil Recovery with Nanofilms
Challenge: Traditional Enhanced Oil Recovery (EOR) faces challenges with premature water breakthrough and inefficient displacement in heterogeneous reservoirs. Conventional agents are often environmentally problematic.
Solution: The ACIS-synthesized cyclodextrin (CD) nanofilms exhibit superior mechanical strength (up to 8.65 MPa critical pressure) and selective permeability, allowing efficient displacement from smaller pores. Their biocompatible nature provides a green alternative.
Impact: Achieves efficient oil recovery by improving adaptability to subsurface heterogeneity and minimizing environmental impact, leading to more sustainable and effective petroleum extraction processes.
