Strain-Controlled Switching of Hierarchically Wrinkled Surfaces between Superhydrophobicity and Superhydrophilicity

Submitted by Zuoqi Zhang on

Recent years have witnessed intense interest in multifunctional surfaces that can be designed to switch between different functional states with various external stimuli including electric field, light, pH value, and mechanical strain. The present paper is aimed to explore whether and how a surface can be designed to switch between superhydrophobicity and superhydrophilicity by an applied strain.

Concrete cracking and durability (first entry)

Why is glass brittle?

Submitted by amohajerani on

What makes glass brittle? I am posting this because I don't have a good answer for it, although I can think of three reasons:

 

-
The disordered structure of glass.  The problem with this explanation
is that silica is brittle in both ordered (quartz) and disordered (fused
silica) forms.

 

-
The covalent type of atomic bonds. The problem with this explanation is
that metallic glasses do not have covalent bonds, but are brittle.

 

Deformation rates and localization of an active fault system

Submitted by saberelarem on

The Corinth Rift in Greece is one of the most active extensional regions in the Mediterranean area (Fig. 1). The Corinth Rift Laboratory project (CRL, http://crlab.eu) is based on the cooperation of various european institutions that merge their efforts to study fault mechanics and related hazards in this natural laboratory where numerous continuous observations are made. The present rift is asymmetric and deformation is very localized.
