The best Samsung Galaxy S24 screen protectors: our 10 favorites

admin

The Samsung Galaxy S24 may not be a seismic shift, but it has allowed Samsung to make some strong improvements to an already solid formula. One of the biggest comes to the display, which has increased in size to 6.2 inches, but crucially, now comes with a dynamic refresh rate that shifts between 1-120Hz. While not a tangible change on the level of the new Galaxy AI features, this improvement brings the phone up to the level of the ultra-flagship

Die Suche nach der Nachbildung des stärksten Materials der Natur

admin

Die außergewöhnlichen mechanischen Eigenschaften von Napfschneckenzähnen beruhen auf ihrer Verbundstruktur: einem flexiblen Gerüst aus Chitin (einer häufig in Insekten, Krebstieren und anderen Organismen vorkommenden Substanz), verstärkt mit Nanokristallen einer Eisenoxidform namens Goethit.

Die Ausnutzung der Stärke eines solchen Materials könnte Lösungen für einige technische Herausforderungen bieten. „Es gibt viele Technologieanwendungen, die durch die Festigkeit und Zähigkeit der Materialien begrenzt sind“, sagt Nicola Pugno, Forscherin an der Universität Trient in Italien, die an der Studie von 2015 beteiligt war.

These moisture-sucking materials could transform air conditioning

admin

Rather than small silica beads, Blue Frontier’s cooling technology relies on a salt solution that’s so concentrated, it can pull moisture from the air.  

Here’s how Blue Frontier’s cooling system works: first, a stream of air passes through a channel and over a thin layer of desiccant, which pulls moisture out of the air. Next, the now-dry air goes through an evaporative cooling step, which lowers the temperature of the air (basically the same way sweat cools your skin).

Tear-resistant rubbery materials could pave the way for tougher tires

admin

A new material design could reduce pollution where the rubber meets the road.

Strategically adding weak points along microscopic chains called polymers actually makes them harder to tear, researchers report in the June 23 Science. Because polymers are used in car tires, the findings could help reduce plastic pollution as tires wear down over time.

When tires scrape against the road, they drop tiny particles of rubber and plastic polymers, which pollute waterways and contaminate the air (SN:

admin

If you’ve ever purchased a pair of faux-leather sandals without realizing they were faux, the sandals probably cleared up that misunderstanding for you pretty quickly. Both real and fake leather can shred your feet on first meeting, but the real stuff will eventually stretch, bend, soften, and mold itself to your needs.
