Low‐Cost, Large‐Scale Nanoporous Metals by Mechanical Alloying, Oxide Reduction, and Dealloying of Powders

Advanced Engineering Materials, EarlyView.
Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...

Determining the Aspect Ratio of a wing based on its Mean Aerodynamic Chord [PDF]

Científica
The aspect ratio of a wing has its origin in the concept of slenderness, understood as the visual aspect that results from comparing its length with its width, that is, its span between its chord, but considering a rectangular shape, it which, in turn ...

Planar Solid‐State Nanopores Toward Scalable Nanofluidic Integration Based on CMOS Technology

Advanced Engineering Materials, EarlyView.
We present a scalable silicon‐based fabrication strategy for planar solid‐state nanopores to enable their integration with complex nanofluidic systems. Prototype devices demonstrate normal voltage‐current characteristics, good noise performance, and appreciable streaming currents. Our CMOS‐compatible fabrication process offers precise geometric control

Considerations Concerning the Impact of the Management on Pine Trees Drying Phenomenon

Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Agriculture, 2016
The pine trees may support the consequences of the action of a series of various natural harmful factors, as break downs determined by strong winds, storms, or large amounts of snow, pathogens and mites’ attacks, and also anthropogenic harmful factors ...
