A photograph of the fracture surface in a silicone model, across both fracture planes, shows that the crack profile has a certain curvature

Secrets, cracks and fractures

It turns out that the shorter a crack in brittle materials - the more resistant they are to it, which can help in the design and use of applications that are based on brittle materials

"Technology accelerates human evolution"

  • One response
Dr. Lonnie Johnson, an inventor who registered over 100 patents and developed a solid-state battery based on them, describes human evolution as an interactive process between biology and technology, in which each influences and is influenced by its own
A graphic illustration of the properties of the titanium-air battery, in the style of the periodic table of the chemical elements, with the unique electrical and energetic characteristics and properties of the innovative battery. This is how the researchers and developers of the titanium-air battery envision it: removing the oxide protective layer on top of titanium is likened in their eyes to the old Titan, full of tremendous energy but imprisoned in a dark cave for ages. The group of scientists discovered a way to break through the "passive" barrier and release the energy stored in the one-eyed giant - the chemical energy stored in it turns, in the structure of the innovative battery, into electrical energy.

What is the most expensive part of an electric vehicle?

Switching to an electric car may save thousands of shekels a year, most of us know that. But what are the unique maintenance and care expenses for the electric vehicle - and what is the biggest expense?
