Researchers Cut Metal with Ceramic Nanoparticles

The scientists started with a low concentration of nanoparticles, adding just 1% by volume silicon carbide nanoparticles into the molten alloy. Evaporating the alloy within a vacuum furnace concentrated the nanoparticles, resulting in a final composition of ~14% silicon carbide and ~86% magnesium, the team reports in Nature .

Future Technology

Using a nanoparticle self-stabilization mechanism in molten metal, scientists can achieve dense uniform dispersion of silicon carbide nanoparticles. Magnesium is 75% lighter than steel and 60% lighter than titanium The magnesium infused metal, has record

A novel isotropic conductive adhesive with Ag flakes, BN …

Isotropic conductive adhesives (ICAs) with lower bonding temperature, higher resolution and environmental friendly have been used extensively in packaging process. In order to improve the electrical and thermal conductive properties of ICAs, two kinds of bimodal high temperature stable ICAs with matrix SHT6 and fillers with composition of macro silver flakes and boron nitride nanoparticles or

Experiments on the wear characteristics of A356 MMNCs …

Since Nano silicon carbide (SiC) and A356 are close in terms of density, SiC has been selected as reinforcement material. addition of 0.5 wt % of nanoparticles, the wear resistance of the nanocomposites improved by 53.735% and 47.04% at aluminium alloy.

This paper reports a simple and rapid method for the synthesis of metallic zirconium nanoparticles with an average size of 63 nm by reducing zirconia at 750 C. The TEM images show particles without a specific shape and the XRD measurements indie that

Magnesium Nano-composite Has ''Record Breaking'' …

Researchers from UCLA have created a new kind of metal composite made from magnesium infused with silicon carbide nanoparticles, and it’s both lightweight and super-strong.

Luminescent silicon carbide nanocrystallites in 3C …

We report optical emission of SiC nanocrystallite films, which clearly shows the quantum confinement effect. Bulk polycrystalline 3C-SiC was first electrochemically etched and then the fabried porous silicon carbide was ultrasonically treated in water or toluene suspension to disperse into colloidal nanoparticles. Transmission electron microscopy images clearly show that the colloidal

Missouri S&T – News and Events – Researchers’ work …

They found a way to mix silicon carbide nanoparticles into a molten magnesium-zinc alloy that uniformly dispersed and stabilized the nanoparticles, making a super-strong and lightweight metal. Through compression tests, Chen and his colleagues proved that the silicon carbide nanoparticle-infused magnesium metal was substantially stronger than conventional metals that did not contain nanoparticles.
