Understanding Curly Hair Mechanics: Fiber Strength [PDF]

open access: yesJournal of Investigative Dermatology, 2020
The relationship between the geometric and mechanical profiles of hair fibers has been studied, with special focus on curly samples. Incidental observations pointed to a significantly different viscoelastic character with varying curliness. Further investigations confirmed initial observations, showing an initial distinct toe region behavior for curly ...

Mechanical strength of highly porous ceramics [PDF]

open access: yesPhysical Review B, 1991
This paper reports on the mechanical strength of highly porous ceramics in terms of the Weibull and Duxbury-Leath distributions. More than 1000 side-crushing strength tests on silica-catalyst carriers of various particle sizes have been performed in series. Within a series, preparation conditions were kept constant.

Ultrathin acoustic metamaterial as super absorber for broadband low-frequency underwater sound

open access: yesScientific Reports, 2023
In this work, an ultrathin acoustic metamaterial formed by space-coiled water channels with a rubber coating is proposed for underwater sound absorption. The proposed metamaterial achieves perfect sound absorption ( $$\alpha$$ α  > 0.99) at 181 Hz, which

Study of the Mechanical Strength Improvement of Wafers for EWT Solar Cells by Chemical Etching after the Drilling Process [PDF]

open access: yes, 2011
Mechanical stability of EWT solar cells deteriorates when holes are created in the wafer. Nevertheless, the chemical etching after the hole generation process improves the mechanical strength by removing part of the damage produced in the drilling ...
