Summary: There is a high demand for a highly mass-producible technology for manufacturing moth-eye-structured films with antireflection function. Conventional films are made using roll-to-roll ultraviolet nanoimprint lithography with aluminum, but the process is complicated and time-consuming. To solve this problem, a sputtering process for forming a thin film of glassy carbon on a roll substrate was proposed, which resulted in a moth-eye structure through oxygen plasma irradiation. The glassy carbon roll mold showed superior antireflection, water repellency, and productivity compared to the moth-eye-structured film made with porous alumina.

Summary: Utilizing a flexible nylon mesh template, re-entrant structures can be easily imprinted in one step without damage. Pre-coated silica nanoparticles and epoxy resin not only improve liquid repellency by introducing hierarchical surface structures, but also act as a protective layer against mechanical abrasion.

Summary: To improve the performance of non-contact thermography, night surveillance, and night driving assistance infrared imaging systems, highly integrated optical lenses with miniaturization features are in demand. In this study, we fabricated refractive microlens arrays (MLAs) with high numerical aperture (NA) and high integration on commercial chalcogenide glass (As2Se3) using photoresist thermal reflow and soft mold imprinting process. The microlenses on PDMS-type concave MLAs (PDMS-MLAs) were transferred to the surface of As2Se3 glass, resulting in chalcogenide glass-based MLAs (ChG-MLAs) with good structure uniformity and focusing capability.

Summary: In this study, a joint laser process of laser shock polishing & imprinting (LSPI) is proposed to efficiently fabricate large-area nanostructures on the surface of cheap industrial aluminum foil. LSPI tailors the laser parameters of single laser manufacturing equipment to apply laser shock polishing (LSP) to polish the aluminum foil, and then laser shock imprinting (LSI) to obtain nanostructures with high accuracy, integrity, and uniformity. The LSPI method improves the yield of the LSI process by decreasing the surface roughness of the aluminum foil through LSP, reduces aluminum residue inside the silicon mold, and investigates its working mechanism for future low-cost and efficient batch fabrication methods for metallic nanostructures.

Summary: This paper compares two commonly used glass GEM structural designs and shows that the optical transparency of the hexagonal symmetric structure is superior to that of the rectangle structure. An electric field model is developed to characterize the negative correlation between the hole diameter and the electric field strength. A new process method of surface metal patterning using hole filling to form a mask is proposed, which can meet the high alignment and shaping requirements. A glass GEM sample with specific dimensions is successfully obtained.

Summary: In this study, highly crystalline fibers of N-alkyl diketopyrrolopyrrole dithienylthieno[3,2-b]thiophene (DPP-DTT) were successfully fabricated using an anodic aluminum oxide (AAO) template-assisted method. The single-crystal-like DPP-DTT fibers exhibited highly ordered molecular chains and crystalline structures, leading to improved charge carrier mobility and light responsivity in organic field-effect transistors (OFET). This work demonstrates a facile and effective approach for fabricating high-molecular-weight polymer semiconductors and achieving high-performance OFET devices, while also expanding the application of AAO template method for crystalline semiconducting polymer fibers and providing new insights into polymer crystallization.
