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

Advanced Materials Technologies, Volume 11, Issue 18, 18 September 2026.
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.

Bridged h‐BN Nanosheets Coatings: Simultaneous Shielding Atomic‐Oxygen Irradiation and Achieving Superior Friction Performance

Advanced Science, Volume 13, Issue 50, 7 September 2026.
ABSTRACT To confront extreme space environments, a combination of inorganic and organic coatings can provide a pathway for offering highly durable radiation resistance and anti‐friction simultaneously. Herein, a strong interfacial 3D hydrogen‐bonding network is designed to create robust hexagonal boron nitride (h‐BN) based polymer coatings with ...

2D Inorganic Electrides: Interstitial Electrons as Key Drivers of Multifunctional Properties and Applications

Advanced Science, Volume 13, Issue 50, 7 September 2026.
Eight AB‐type 2D inorganic electrides with negatively charged transition metals are theoretically designed. Their monolayers exhibit intrinsic magnetic ordering, rich topological phases, and ultralow work functions. Supported metal Ru on these 2D inorganic electrides effectively alleviates hydrogen poisoning and enables efficient ammonia synthesis ...

Performance assessment of reversible friction materials: Preliminary tests

ce/papers, Volume 9, Issue 2-3, Page 1757-1762, September 2026.
Abstract Friction joints represent an effective solution for limiting damage in steel structures subjected to extreme actions; however, their application is often constrained by degradation of friction materials and loss of repeatability under cyclic activation, which undermine repairability and post‐event reliability.
