Parametric Study on Slenderness Ratio of Concrete walls With Openings

, 2005
Available studies have illustrated the conservative nature of empirical wall design equations provided in major codes of practice such as AS3600 and ACI-318. Furthermore these equations fail to recognise walls that are supported on all four sides, walls

Carboxylic‐Acid Functionalized Multiwalled Carbon Nanotube‐Alkane‐Based Resistive Temperature Sensor for Cold Chain Applications

Advanced Engineering Materials, EarlyView.
This study presents a reversible temperature sensor with high switching ratio, ∼103. The device is fabricated using PET‐ITO and carbon nanotube dispersions in alkane. Considering its application in cold chain logistics, a proof‐of‐concept with LED is showcased. Thus, a temperature drop below the threshold temperature (crystallization temperature of the

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 ...

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 ...
