Summary: This paper examines the nanoscale surface instability of ultrathin molecular films deposited on a substrate under uniaxial compression using molecular dynamics simulations. The study reveals the development of one-dimensional wrinkling structures and the scaling relationship between wavelength and film length. It is found that small compressions can be well described, while large compressions lead to increased wrinkling amplitudes with nearly constant cross sections, offering a novel interpretation of instability. These findings may be crucial for designing effective wrinkling and buckling patterns in flexible platforms for electronics and photonics.

Summary: Stripe patterned nanofiltration membranes were prepared by regulating the interfacial polymerization process using sulfonated polyether sulfone nanoparticles. The nanoparticles confined the diffusion of piperazine towards the organic phase, resulting in the formation of intensive nanoscale stripes uniformly distributed throughout the membrane. The generation and evolution of the membrane structure from conventional nodular structures to stripe patterns were investigated by optimizing the membrane thickness and incorporating different concentrations of nanoparticles. The resulting membrane, SPES-1.0@NFM-II, showed a distinctive morphology with interconnected labyrinthine networks on both surfaces of the active layer and exhibited enhanced water permeance and excellent divalent salt rejection.

Summary: The study revealed that the physicochemical heterogeneity created by the AuNPs on the PDMS surface could guide the hole-formation and affect the spacing and periodicity of the droplets formed, with the size and spacing of the holes and droplets being tunable by varying the nanoparticle loading. Compared to dewetting on homogeneous PDMS surfaces, the AuNP guided patterns showed ten-fold miniaturization, resulting in high-density random patterns on the PDMS substrate.

Summary: Polyamide films were grown on Si(111) using a MLD process and then pyrolyzed to yield crystalline SiC thin films. The synthesized 3C-SiC films showed heteroepitaxial nature with respect to the Si(111) substrate, and the formation of single-crystal SiC films was confirmed by various analysis techniques. The pyrolysis temperature affected the formation of defects in the samples, and the highly conformal SiC films were demonstrated using Bosch-processed Si trenches.
