Dangerous Train Routes In The World… 😳 😘❤️

As you climb these steps, make sure to watch where you step. Here are some of the most spectacular and dangerous staircases in the world. Stairs have been built for a very long time to aid in the ascent of heights and to lessen the amount of work that is required for this. However, in other regions of the world, stairs are so terrible that they appear to be nothing more than a series of corridors going to the underworld.

Silicon wafers produced by the Czochralski process with micrometer-scale pyramidal structural elements on their surfaces are significantly cheaper.

These microtextures capture more light because they are less reflective than a smooth surface. However, coating these wafers with perovskite results in many defects in the crystal lattice, which affect the electronic properties.

However, the team of researchers has developed a strategy for surface passivation that allows the surface defects of the perovskite layer to be smoothed out.

Microwave technology has dramatically progressed, marked by the arrival of the 5G era, owing to the advantages of electromagnetic waves in long-distance, wireless, and high-speed transmissions. However, electromagnetic wave pollution problems such as electromagnetic wave interference and electromagnetic wave radiation are becoming increasingly serious.

Electromagnetic wave pollution not only affects the normal operation of electronic equipment, greatly threatens the information security of the scientific community, but also endangers human health and is a possible cause of cancer and sensitized diseases.

SiOC precursor ceramics have great application potential in electromagnetic protection because of their advantages such as lightweight, high-temperature resistance, and molecular designability. The main challenge of polymer-derived ceramic-based composites for electromagnetic wave absorption is the single loss mechanism, resulting in inferior electromagnetic wave attenuation ability.

It looks like Elon is about to rescue two people Boeing left stranded in outer space. Crew Dragon’s capacity will likely be increased from 4 to 6 people as the solution to this problem.

SpaceX is actively working on a plan to fly Starliner’s crew home.

America has found the ‘Mine of the Apocalypse’ with energy for millennia: 5 trillion of the most futuristic source under these states.

A peculiar leopard-spotted rock, found beside an ancient, dried-out river in Mars’ Jezero crater, contains some tantalizing clues of ancient life, NASA said.

NASA’s Crew Flight Test astronauts Sunita Williams and Butch Wilmore have been aboard Boeing’s Starliner spacecraft, docked at the ISS since June 6.

The find includes two ancient chariots, a wealth of bronze objects, and answers to some lingering questions.

Elon Musk doesn’t expect the next Starship test flight to occur before late August.
