Summary: Phase-gradient metasurfaces manipulate light by changing its phase locally. Our research group has developed a simple method using UV-curable resin printing to fabricate phase-gradient metasurfaces, which reduces processing time, cost, and safety hazards. We demonstrated the advantages of this method by rapidly reproducing high-performance metalenses based on the Pancharatnam-Berry phase gradient concept in the visible spectrum.

Summary: Antimicrobial films based on starch, poly(butylene adipate-co-terephthalate) (PBAT), and AgNPs@SiO2 were produced with good compatibility and antibacterial activities. The composite films loaded with 1 wt% AgNPs@SiO2 showed nearly 90% inhibition efficiency on Staphylococcus aureus and Escherichia coli, and exhibited extended shelf life for peaches and nectarines. The high-throughput production method and strong antibacterial activities make them promising for commercial applications as antimicrobial packaging materials.

Summary: In this work, atomic layer deposition (ALD) was used as a short post-fabrication step to increase the refractive index (RI) of nanocrystal (NC)-based films and patterned nanostructures. The RI of TiO2 NC-based films was increased from 1.95 to 2.15 by ALD, and the number of ALD cycles could be adjusted to achieve desired intermediate RI values. The use of ALD resulted in a denser structure and improved optical performance of the nanostructures, as demonstrated by the increased focusing efficiency of metalenses.

Summary: The use of a secondary laser source in photoinhibition lithography enhances the resolution of multiphoton 3D nanoprinting processes. However, the complex photo-chemical dynamics and interactions involved in this process are not well understood. This study investigates the photoinhibition process of the common photoinitiator DETC in low peak intensity, high repetition rate 3D nanoprinting processes and demonstrates inhibition of the polymerization process. It also explores options for recovering the photoinhibition process in high intensity, low repetition rate lasers and demonstrates photoinhibition in a projection multiphoton printing system.
