Dying satellites create aluminium oxide particles in the mesosphere, 50–85km (30–50 miles) above Earth’s surface. But the ...

Raw aluminium readily forms a tough oxide layer when exposed to air, which protects the metal from further corrosion or reactions with many chemicals. This oxide layer can form incredibly quickly ...

Aluminum doesn’t solder well, and that’s because of the oxide layer that rapidly forms on the surface. [Ted]’s solution is to scour the aluminum with some mineral oil. The goal is to scrape ...

Microstructural analysis using advanced electron microscopy revealed the penetration of lithium into the α-Al 2 O 3 layer, leading to the chemical transformation. "The lithium-aluminum oxide ...

Re-entries of SpaceX Starlink satellites are causing environmental concerns by releasing aluminium oxide, which could harm the ozone layer. Scientists are worried about its lasting impact.

Often, the dielectric layer is not pure hafnium oxide, either, but a laminate, with zirconium or aluminum oxide layers, too. Each precursor for each layer must have compatible chemistry and process ...

In 2022, 18.7 tons of aluminum oxide nanoparticles were released into ... was producing a massive hole in the ozone layer. A 1987 ban on CFCs helped slow the process, and by 2013, authorities ...

“We found that aluminium and magnesium oxide impurities ... During heating, the oxide layer undergoes a process of dehydration, melting and evaporation. Each of these steps occurs at a different ...

Aluminium is unusual because it is a reactive metal that does not react with water. Its surface naturally forms a very thin layer of aluminium oxide that keeps water away from the metal below.

The substrate was an “ultrathin” and transparent-conductive-oxide-free 1.4-μm-thick polymer foil coated with a layer of 100 nm aluminum oxide. It effectively served as a “barrier” to ...

The research group proposed to address the analyzed degradation mechanisms by introducing on the cell front side a 10 nm aluminum oxide (AlOx) barrier layer, deposited via atomic layer deposition ...

While mesmerizing, satellite re-entries release aluminium oxide nanoparticles, which could impact the ozone layer for decades before we see the damage. With 8,000+ Starlink satellites launched and ...
