Summary: In this study, a solvent evaporation-induced self-assembly method was innovatively proposed to produce superhydrophobic surfaces (SHS) with facile prepared, environmentally friendly, and ultrafast ambient temperature curable properties. The surface superhydrophobicity and morphology of the SHS can be readily tuned by varying the spraying concentrations, diisocyanates, solvents, spraying heights, and molecular weight of PDMS. The formation mechanism of the SHS was investigated through small-angle scattering and X-ray photoelectron spectroscopy.

Summary: This study presented the fabrication of an icephobic coating for steel using a silicone-epoxy hybrid resin. The coating exhibited good mechanical properties and weathering resistance for outdoor applications. Through various tests, the correlation between ice adhesion strength and Young modulus was examined, and the best-performing matrix was obtained by altering the surface energy characteristics with fluorinated silicone additives. The optimized coating showed a significant reduction in ice adhesion strength for steel substrates.

Summary: This study investigates ice nucleation time on superhydrophobic surfaces using both experimental testing and machine learning approaches. The experimental results show that superhydrophobic surfaces with higher roughness parameters have longer ice nucleation times. The predicted ice nucleation time from the machine learning model agrees well with the experimental outcomes. The study also determines the relative importance of different parameters in determining surface icephobicity.

Summary: In this study, a patterned surface with two different non-wetting characteristics was developed to control the transport behavior of water droplets. The surface exhibited excellent water-repellant properties in the superhydrophobic region, with a water contact angle of 160 degrees. The maximum transport distance and average transport velocity of droplets were observed on different wedge-shaped surfaces, indicating the driving force provided by the surface for droplet transport. The surface non-wetting gradient and wedge-shaped pattern created unbalanced surface tension and generated Laplace pressure inside the water droplet during the transport process.

Summary: Block copolymer (BCP) self-assembly is a promising method for generating features for integrated circuits and memory devices. However, it is challenging to select a common good solvent for high-x BCPs and control the alignment of phase separated morphologies. In this study, we synthesized a series of BCPs and demonstrated the ability to switch between different morphologies and achieve lamellar patterning with domains as small as 14 nm on a wafer.

Summary: In this study, a facile strategy called photoinduced alignment under solvent vapor annealing (PA-SVA) is proposed to form well-aligned block copolymer thin films without the need for chemically or topographically prepatterned substrates. The light-assisted self-assembly of the block copolymers is achieved by incorporating light-responsive azobenzene molecules into the polymer chains. The alignment of the block copolymer chains is induced through supramolecular interactions between the azobenzene molecules and the polymer chains. This method not only allows for manipulation of the position of light-responsive molecules in block copolymer chains, but also provides an alternative way to obtain well-ordered block copolymer thin films.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: This study explores the potential of biphenylene as a nanocarrier for the delivery of the anticancer drug cisplatin. It is found that biphenylene offers physical stability, rapid release rate, solubility, and bio-compatibilities compared to other nanocarriers. The adsorption of cisplatin on the surface of biphenylene involves charge transfer from cisplatin to biphenylene. The drug is shown to be released at body temperature in an acidic environment. Biphenylene also exhibits excellent cytotoxicity activity and cellular uptake of the drug. Overall, biphenylene shows promise as a potential nanocarrier for cisplatin delivery.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
