Photoactivation of NV Centers in Diamond via Continuous Wave Laser Illumination of Shallow As‐Implanted Nitrogen

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates an alternative method of creating charge‐stable negatively charged nitrogen vacancy (NV−) centers close to the diamond surface without high‐temperature annealing. By illuminating nitrogen‐implanted regions with a continuous‐wave 405 nm laser, NV− centers are induced, exhibiting electron spin coherence properties suitable for ...

Vertical Wind Tunnel for Prediction of Rocket Flight Dynamics

open access: yesAerospace, 2016
A customized vertical wind tunnel has been built by the University of Canterbury Rocketry group (UC Rocketry). This wind tunnel has been critical for the success of UC Rocketry as it allows the optimization of avionics and control systems before flight ...

A wind-tunnel investigation of wind-turbine wakes in yawed conditions

open access: yes, 2015
Wind-tunnel experiments were performed to study the performance of a model wind turbine and its wake characteristics in a boundary layer under different operating conditions, including different yaw angles and tip speed ratios.

Ternary Transistors With Reconfigurable Polarities

open access: yesAdvanced Functional Materials, EarlyView.
Polarity‐reconfigurable ternary transistors are demonstrated using black phosphorus homojunction with asymmetric contacts and split‐gate structures. Suppression of majority carrier injection, while Fowler–Nordheim tunneling of low‐density minority carriers persists, enables a well‐defined intermediate state with improved on/off ratios.

A technique for reducing supersonic transient loads on internal wind tunnel balances [PDF]

open access: yesTehnika
Design of slender supersonic missiles requires a comprehensive experimental support in the form of wind tunnel data for a wide range of flight parameters (angle of attack and Mach number). However, in supersonic wind tunnel testing, the problem exists of

Study of the integration of wind tunnel and computational methods for aerodynamic configurations [PDF]

open access: yes
A study was conducted to determine the effectiveness of using a low-order panel code to estimate wind tunnel wall corrections. The corrections were found by two computations.

Towards the virtual wind tunnel

open access: yes, 2017
The maturity of numerical techniques both in Computational Structural and Fluid Dynamics, accompanied by the availability of affordable high-performance hardware, allows the use of virtual rapid-prototyping facilities as realistic alternatives to traditional wind tunnel experiments.

Vanadium Doped Magnetic MoS2 Monolayers of Improved Electrical Conductivity as Spin‐Orbit Torque Layer

open access: yesAdvanced Functional Materials, EarlyView.
Electrically conductive and room temperature magnetic atomically thin (≈0.8 nm) vanadium doped MoS2 (V‐MoS2) is demonstrated for its spintronic applications. Here, the spin transport at the interface of permalloy (Py) and high spin‐orbit coupling V‐MoS2 magnetic monolayers is shown.
