Coating‐Free Nanoscratching for Liquid‐Crystal Alignment on PCB‐Compatible Millimeter‐Wave Reflective Unit Cells

open access: yesAdvanced Materials Technologies, EarlyView.
Direct nanoscratching with a 500 nm diamond lapping film creates groove‐guided liquid‐crystal alignment interfaces on PCB‐compatible Cu‐patterned RF substrates within minutes, eliminating polymer coating and high‐temperature baking. The coating‐free process enables optical/molecular alignment validation and voltage‐programmable 28 GHz reflection‐phase ...

Passive Directional Water Transport on Superhydrophobic Gradient Textures Fabricated by Direct Laser Interference Patterning

open access: yesAdvanced Materials Technologies, EarlyView.
Microstructures fabricated by two‐beam DLIP combining spatial‐period and roughness gradients are fabricated to enhance directional transport of water droplets. The coupled gradients increase transport distance by 160% and strongly suppress motion against the gradient, demonstrating an effective strategy for controlled droplet manipulation.

Rotating Fluorescent Nanodiamond Assemblies With Focused Laguerre–Gaussian Beams

open access: yesAdvanced Optical Materials, EarlyView.
Self‐assembled fluorescent nanodiamond clusters are optically trapped and driven into controlled two‐dimensional rotation with Laguerre–Gaussian beams. With localized optical excitation, optically detected magnetic resonance spectra are collected at defined points along the orbit in a uniform external magnetic field.
