Scalable Thermal Engineering via Femtosecond Laser‐Direct‐Written Phononic Nanostructures
Advanced Functional Materials, EarlyView.This study demonstrates that femtosecond laser‐induced periodic surface structures (fs‐LIPSS) can function as phononic metasurfaces, reducing thermal conductivity below the plain thin‐film limit. Phonon Monte Carlo analysis reveals that the periodic structures restrict phonon mean free paths.

Prediction of transonic flutter for a supercritical wing by modified strip analysis and comparison with experiment [PDF]
Use of a supercritical airfoil can adversely affect wing flutter speeds in the transonic range. As adequate theories for three dimensional unsteady transonic flow are not yet available, the modified strip analysis was used to predict the transonic ...

Advanced Functional Materials, EarlyView.A self‐gelling PG@PAC (POD/Gel‐CDH@PA/CHX) powder is developed for infected burn care in austere settings. Upon contact with wound exudate, it instantly forms an adhesive hydrogel, providing simultaneous hemostasis, broad‐spectrum antibacterial activity, reactive oxygen species scavenging, and immunomodulation. In a murine model of S.

Transonic flutter analysis of an AGARD 445.6 wing in the frequency domain using the Euler method
Engineering Applications of Computational Fluid Mechanics, 2016 A method based on the Euler equations is proposed for solving transonic flutter problems. The transonic nonlinear flow field with local shock wave/boundary layer interaction is obtained by the Euler/boundary layer equations, and the aerodynamic forces ...

Experimental Evaluation of Transonic Stators Preliminary Analysis and Design Report [PDF]
A flow-generating rotor has been designed under NASA contract NAS3-7614 to enable three transonic stators to be tested. The stators were designed by NASA in conjunction with the Contractor. Design analyses were conducted and the results indicate that the

Advanced Functional Materials, EarlyView.Hydrocarbon membranes are a greener alternative to PFSA in PEM fuel cells, but degrade rapidly from radical attack. We present a novel strategy using poly(vinylphosphonic acid) (PVPA) as a local radical scavenger. Incorporated as an interfacial barrier, PVPA enhances chemical stability and significantly extends membrane lifetime under accelerated ...
