THE chromium–aluminium oxide catalyst system is one most commonly used in the aromatization of paraffinic hydrocarbons. In practice, mixtures containing up to 20 per cent chromium oxide are used, this ...

FRÖHLICH'S theory of dielectrics predicts an increase in the electric strength as the thickness of the dielectric specimen approaches the electronic mean free path. This prediction has been verified ...

Researchers from the Ateneo de Manila University and the Nara Institute of Science and Technology made transparent aluminum oxide (TAlOx) by applying microdroplets of acidic solution onto ordinary ...

With the unique properties of nanomaterials, such as having a high surface-to-volume ratio and a diverse morphology and structure, they have become a desirable material for different applications.

It is not uncommon for a Hackaday writer to trawl the comments section of a given article, looking for insights or to learn something new. Often, those with experience in various fields will share ...

“We don’t need any energy input, and it bubbles hydrogen like crazy. I’ve never seen anything like it,” said UCSC Professor Scott Oliver, describing a new aluminum-gallium nanoparticle powder that ...

Scanning electron microscopy of the composite shows aluminum nanoparticles in a matrix of gallium. (Credit: Amberchan et al., 2022) Aluminum is a highly reactive metal that can strip oxygen from water ...

Researchers led by Saudi Arabia’s King Khalid University have developed a 3D-printed anti-reflective coversheet for PV modules. The cover sheet is based on cyclic-olefin copolymers (COC), to which a ...

The thermite process is a handy way to generate molten iron in the field. It’s the reaction between aluminium metal and iron oxide, which results in aluminium oxide and metallic iron. It’s hot enough ...

Russia began sourcing alumina from India following Ukraine war and Australian ban on aluminum exports. Rusal, Russia's major aluminum producer, acknowledges heavy reliance on imported alumina and ...
