Summary: The authors propose a new method to synthesise wind load time series up the height of a building by combining part-model test results, and show that these synthetic wind loads are almost identical to those sampled simultaneously from a complete model. A circular cylinder model with pressure taps was used to study and validate this method, and a detailed mathematical derivation is presented. The results indicate that using uncorrected wind loads from two independent wind tunnel tests underestimates the dynamic response of a chimney, but using the method to combine wind loads from these two tests produces results similar to using simultaneously sampled pressure tap data. This method is of great importance for wind tunnel investigation of high aspect ratio buildings where testing the entire model is not possible.

Summary: A method is proposed to control the final morphology of roll-to-roll slot-die coated poly(3-hexylthiophene) (P3HT) by optically exciting the p-type polymer during coating. This study demonstrates the relationship between the morphology and physical properties of the thin film by combining density functional theory, molecular dynamics simulations, X-ray experiments, absorption spectroscopy, and THz spectroscopy. It is observed that P3HT films excited with light during deposition exhibit higher crystallinity, texture with more face-on orientation, and increased out-of-plane charge mobility.

Summary: A generic approach for designing plasmonic lenses to generate predesigned vector surface plasmon polaritons (SPPs) vortices with high efficiencies is established. The devices, constructed with tailored meta-atoms, can convert normally incident circularly polarized light into desired vector SPP vortices due to phase and polarization matching. Experimental demonstrations of directional SPP conversion (coupling efficiency: 35%; utilization efficiency: 98%) and enhanced efficiency in generating vector SPP vortex pave the way for on-chip plasmonic devices to efficiently utilize SPPs with minimal footprints.

Silicon-based photonic crystals can effectively generate third harmonic waves, providing a simplified approach to on-chip linear and nonlinear circuitry and reducing potential sources of losses by unifying the production chain with the same material, such as silicon.

Summary: Optical sensors are efficient tools used to detect various types of analytes. High-contrast gratings (HCGs) are nanoscale devices that exhibit sharp optical resonances and can be used to detect biomarkers. Among different HCG structures, pedestal HCGs have higher bulk refractive index sensitivity, while half-buried HCGs have higher surface sensitivity. Both types of HCGs were used for optical biosensing of the cardiac biomarker myoglobin, and the half-buried HCGs showed slightly lower limit of detection compared to pedestal HCGs.
