Machine‐Learning‐Assisted Understanding of Depth‐Dependent Thermal Conductivity in Lithium Niobate Induced by Point Defects

open access: yesAdvanced Electronic Materials, EarlyView.
Thermal conductivity, a fundamental property of lithium niobate, plays a pivotal role in determining its device performance. By integrating experiments with machine‐learning‐assisted simulations, this study demonstrates that oxygen vacancies induced by thermal reduction result in a pronounced suppression of thermal conductivity and a marked depth ...

Low speed aerodynamic characteristics of an 0.075-scale F-15 airplane model at high angles of attack and sideslip [PDF]

open access: yes
An 0.075 scale model representative of the F-15 airplane was tested in the Ames 12 foot pressure wind tunnel at a Mach number of 0.16 to determine static longitudinal and lateral directional characteristics at spin attitudes for Reynolds numbers from 1 ...

Ecofriendly Printing of Silver Nanowires with Cellulose Binder for Highly Robust Flexible Electronics

open access: yesAdvanced Electronic Materials, EarlyView.
This work reports ecofriendly silver nanowire based ink with cellulose as the binder for printed flexible electronics. After annealing, the cellulose binder provides excellent adhesion between nanowires and substrate, leading to robust electromechanical performance of the printed electronics without encapsulation.

Aerothermal tests of a 12.5 percent cone at Mach 6.7 for various Reynolds numbers, angles of attack and nose shapes [PDF]

open access: yes
The effects of free-stream unit Reynolds number, angle of attack, and nose shape on the aerothermal environment of a 3-ft basediameter, 12.5 deg half-angle cone were investigated in the Langley 8-foot high temperature tunnel at Mach 6.7.
