High-efficient nanoemulsions separation by surface manipulation of sands.

Oil-in-water (O/W) nanoemulsions, prevalent in the cosmetics, pharmaceutical, and petroleum industries, present significant threats to aquatic ecosystems and human health upon their inadvertent release into the environment. However, the nanoscale droplet size and robust interfacial film of nanoemulsions confer exceptional stability, rendering their separation a formidable challenge. Developing an economical and efficient method to remove nanoemulsions is crucial, offering a cost-effective and energy-saving alternative to traditional techniques.

Transparent anti-fingerprint glass surfaces: comprehensive insights into theory, design, and prospects.

With the advancement of information technology, touch-operated devices such as smartphones, tablets, and computers have become ubiquitous, reshaping our interaction with technology. Transparent surfaces, pivotal in the display industry, architecture, and household appliances, are prone to contamination from fingerprints, grease, and dust. Such contaminants compromise the cleanliness, aesthetic appeal, hygiene of the glass, and the overall user visual experience.

Damage Tolerance of Superhydrophobic Coatings with Binary Cooperative Cells for Water Harvesting.

Multifunction superhydrophobic coatings that facilitate water harvesting are attractive for addressing the daunting water crisis, yet, they are caught in a double bind when their durability is considered, as durable coatings will require both tough micro-textures to survive concentrated stress and high-surface-energy chemistry to form chemical bonds within the matrix. To date, a universal bulk-phase coating that combines multifunctionality, ultra-durability, and fabrication feasibility remains challenging. Here, a binary cooperative cell design is reported that can solve the contradiction between the multifunctionality and durability requirements of superhydrophobic coatings.

Ultra-durable superhydrophobic cellular coatings.

Developing versatile, scalable, and durable coatings that resist the accretion of matters (liquid, vapor, and solid phases) in various operating environments is important to industrial applications, yet has proven challenging. Here, we report a cellular coating that imparts liquid-repellence, vapor-imperviousness, and solid-shedding capabilities without the need for complicated structures and fabrication processes. The key lies in designing basic cells consisting of rigid microshells and releasable nanoseeds, which together serve as a rigid shield and a bridge that chemically bonds with matrix and substrate.

Waterborne superamphiphobic coatings with network structure for enhancing mechanical durability.

Superamphiphobic coatings may significantly change the wettability of a substrate, and so are attractive for applications in aero/marine engineering, biotechnology, and heat transfer. However, the coatings are caught in a double bind when their durability is considered, as they are vulnerable to mechanical abrasion. Meanwhile, the wide use of organic solvents for preparing the coatings generates environmental pollution.

Study on the molecularly imprinted polymers with methyl-testosterone as the template.

Molecularly imprinted polymers (MIPs) using methyl-testosterone as the template, methacrylic acid (MAA) as the monomer and ethylene glycol dimethacrylate (EDMA) as the crosslinker were prepared by precipitation polymerization. The morphology of the obtained particles was characterized by scanning electron microscopy (SEM) and the pore size was measured by BET. Then, the specificity and selectivity of the MIPs were evaluated using the equilibrium rebinding experiments.
