Summary: Fiber-shaped solar cells have great potential in wearable electronics, with fiber-shaped organic solar cells being the most promising candidate. This study demonstrates efficient fiber-shaped organic solar cells using non-fullerene acceptors as light-harvesting materials, and systematically investigates the factors influencing their performance. The results show that fiber-shaped organic solar cells can not only power electronic devices but also be woven into textiles to charge smartwatches.

Summary: This study demonstrates a highly transparent and flexible artificial synapse with a two-terminal architecture that emulates photonic synaptic functionalities, exhibiting characteristics such as paired-pulse facilitation, short/long-term memory, and synaptic behavior analogous to that of the human eye. The ability to detect deep red light without impacting synaptic behavior indicates dual-mode operation potential, contributing to higher integration density of transparent 3D stacking memristors and potential applications in optical learning, memory, computing, and visual recognition.

Summary: This paper investigates the influence of the size of nongrouted anchor nails on the anchorage capacity in a flexible protected system. Lateral pullout tests were conducted to analyze the deformation, pullout capacity, and failure modes of anchor nails with different lengths and diameters. Theoretical models were established for different failure modes and the applicability of these models was verified. The results show that the length and diameter of the anchor nails have significant impacts on their bending length, pullout capacity, and failure modes.

Summary: Flexible UCNP-embedded film coupled with a microsphere photonic superlens (MPS) can achieve giant UCL enhancement. The pathways of MPS-enhanced UCL include Mie-resonant nanofocusing, optical whispering-gallery modes (WGMs), and the directional antenna effect. The contribution of optical resonance in the MPS to suppressing nonradiative transition and thermal quenching is experimentally validated.

Summary: This work presents an experimental investigation of the post-fire flexural strength of Filament-wound Glass Fiber Reinforced Polymer (GFRP) tubes. The study reveals that the flexural properties of the GFRP tube are degraded after fire tests, with delamination and matrix cracking as the main observed damage forms. The study also compares tubes assembled according to different standards, showing that the ones assembled according to the NFT standard have higher resistance.

Summary: Magnetic photonic crystals (PCs) have great potential in the field of anticounterfeiting due to their attractive magnetic orientation, flexible pattern designability, and abundant angle-dependent colors. By developing a selective concentration polymerization method, lipophilic magnetic photonic nanochains (PNCs) of full-width at half-maxima below 30 nm were fabricated and used to print robust anticounterfeiting labels. The as-printed labels possess vivid optically variable effects (OVEs), are difficult to imitate and duplicate, and show excellent environmental resistance and mechanical properties, making them suitable for banknotes and high-grade commodities.
