Summary: This study proposes a vibration-assisted UV nanoimprint lithography technique to effectively improve the power conversion efficiency (PCE) of Si solar cells. By applying piezoelectric vibration, the contact area between the photoresist and the grating's side wall is increased, reducing surface tension and increasing the photoresist filling rate by 25%. The best grating parameters are determined using Finite Difference Time Domain (FDTD) and vibration-assisted UV nanoimprint is used to fabricate the periodic grating structures, resulting in a 25% increase in PCE compared to bare Si solar cells.

Summary: In this study, molecular dynamics simulations were used to investigate the filling process of few-nanometer-wide trenches in UV-NIL. The results showed that resist materials with low viscosities were able to successfully fill the trenches, while resist materials with high viscosity could not. The study also compared the properties of linear photopolymers and found that TPGDA, which is more flexible and can adopt more conformations, had a higher probability of intra-molecular crosslinking. These findings provide valuable information for selecting and designing resists for fine patterning in UV-NIL.

Summary: This strategy demonstrates a controllable method to fabricate polymeric nanowires with high throughput and low cost using thermal nanoimprint lithography (NIL) technique and self-assembled anodic aluminum oxide (AAO) template. The length of polymeric nanowires can be adjusted by the duration of thermal NIL, and the fill mechanism of thermoplastic intermediate polymer stamp (IPS) into AAO nanopores is essential for the preparation of SERS-active substrates. The approach shows potential for expanding the use of thermal NIL technique and AAO template for fabricating various nanomaterials, especially flexible and transparent polymer-based nanomaterials.

Summary: Imitating nature and understanding its mechanisms is important for advancing the development of functional materials. This study successfully replicated the micro-nano hierarchical structure of a lotus leaf surface using UV nanoimprint lithography technology. The obtained UV-curable waterborne polyurethane acrylate surfaces exhibited special wetting and superhydrophobic properties. The study showed that higher UV intensity resulted in a more accurate replication of the lotus leaf structure, leading to a larger water contact angle and higher adhesive force.

Summary: A new method for fabricating large-area metal and semiconductor nanobridge arrays is proposed in this article, which combines the possibilities offered by nanotransfer printing and UV lithography. The method involves imprinting an array of nanostrips into a resist layer and subsequent UV exposure through an additional mask to define the regions where suspended nanostrip bridges will be formed. Using this method, large-area arrays of Au and Ti/Au nanobridge, as well as SiGe nanobridge arrays, were successfully fabricated. The proposed method is simple, low-cost, and can be implemented on solid and polymer substrates.

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.
