Plasmon‐Enhanced Second‐Harmonic Generation in Atomically Thin Crystalline Silver Nanostructures

Advanced Materials, EarlyView.
Atomically thin crystalline silver films combine vertical quantum confinement with lateral plasmonic field enhancement to boost second‐harmonic generation. Nanoribbon and nanotriangle arrays enable geometry‐tunable infrared plasmon resonances, producing strong SHG from deeply subwavelength metallic volumes compatible with silicon‐based nanophotonics ...

Wind tunnel blockage corrections forwind turbine measurements

, 2013
Wind-tunnel measurements are an important step during the windturbinedesign process. The goal of wind-tunnel tests is to estimate theoperational performance of the wind turbine, for example by measuringthe power and thrust coecients.

An automated system for navigating object mounts within a wind tunnel facility [PDF]

EPJ Web of Conferences
From an engineering point of view, understanding how the flow behaves downstream from solid objects is essential. The current configuration of the Armfield subsonic wind tunnel (computer controlled C15 − 10 model) does not provide uniform guidance for ...

Synthesis of Bulk Superconducting LiNbO2 Crystals Through CaH2 Reduction

Advanced Materials, EarlyView.
CaH2 reduction reconstructively transforms insulating LiNbO3 single crystals into superconducting bulk LiNbO2 with a critical temperature of Tc = 14.4 K. Scanning electron microscopy reveals large‐volume, high‐yield phase conversion. Magnetization measurements demonstrate a robust ∼ 77% Meissner shielding fraction, establishing bulk superconductivity ...

Turbulence Length Scales in a Boundary Layer Wind Tunnel

, 2001
Turbulence length scales are important parameters affecting the aerodynamic characteristics and response of structures in wind flow. It is therefore essential to simulate the wind velocity profile models in scaling these turbulence length scale ...

A nonlinear controller for flutter suppression: from simulation to wind tunnel testing [PDF]

, 2014
Active control for flutter suppression and limit cycle oscillation of a wind tunnel wing section is presented. Unsteady aerodynamics is modelled with strip theory and the incompressible two-dimensional classical theory of Theodorsen.

Thickness‐Defined Transport Regime Toward Near‐Ideal Area‐Type Switching

Advanced Materials, EarlyView.
By thinning the oxide layer, memristors pass from diode‐like and battery‐effect‐dominated behavior toward eventual short‐circuit failure. Within the intermediate 5–6 nm window, they reach a near‐ideal analog area‐type switching regime, featuring symmetric hysteresis, area‐dependent conductance, and continuous linear programming of HRS and LRS with ...

Hierarchical Multi‐Material Architectures With Gradient Design for Dynamic‐Range Flexible Tactile Sensing

Advanced Materials Technologies, EarlyView.
Hierarchical multi‐material TPMS lattices are engineered as flexible tactile sensors by combining soft and stiff elastomeric layers with a conformal conductive coating. The bilayer architecture delivers sensitivity at low pressures while maintaining a broad detectable range under large loads, enabling reliable pressure and vibration monitoring for ...
