Scaling turbulence drives the general circulation
The NOAA Gulfstream SP4, which deployed the GPS dropsondes over the NE Pacific Ocean as part of the Winter Storms Project during the January–March periods of 2004, 2005 and 2006. Abstract Statistical multifractal analysis of airborne and dropsonde observations is used to show that persistence of velocity after molecular collisions breaks the continuous

Photonic nanovoids for tailored optoelectronic response in silicon solar cells
Optoelectronic workflow followed by experimental validation, demonstrating state‐of‐the‐art efficiency gains. Abstract As crystalline silicon (c‐Si) solar cells become thinner to reduce cost and weight, the optical design principles that govern light trapping (LT) must evolve.

Scalable Room‐Temperature Terahertz Graphene Cameras
ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...

Analysis of sweeping jet and film composite cooling using the decoupled model
The heat transfer process of the sweeping jet and film composite cooling (SJF) structure of the turbine blade leading edge is complex. The current work divides the overall cooling effectiveness of the SJF into the impingement heat transfer effectiveness,

Transpiration Cooling with Circular Air Impinging Jets.
Transpiration cooling effectiveness is influenced by the heat transfer coefficient on both surfaces and the thermal conductivity of the test plate. In the present paper, two circular air jets were perpendicularly impinged on the back surface of the test plate as coolant.
