Spatially defined assembly of colloidal metallic nanoparticles is necessary for fabrication of plasmonic devices. In this study, we demonstrate high-resolution additive jet printing of end-functional ...

A pool cleaner and a spongy polymer can turn used and discarded electronic items into a treasure trove of gold.

Scientists at Flinders University developed a safe, sustainable way to extract gold from e-waste and ore - without mercury or cyanide.

A new gold extraction method turns old electronics into treasure using pool disinfectant and sunlight — no poisons required.

The urgent need for a safer alternative has pushed scientists to explore more sustainable techniques, and now, a promising ...

The new technique eliminates toxic chemicals by using a common disinfectant and a recyclable polymer to recover gold from ...

Colloids are particles that have a diameter of between approximately 1 and 1,000 nanometres and that are evenly dispersed in fluids. Colloids are also known as colloidal dispersions because the ...

Yesterday you felt energized today you feel calm and contemplative You may never have thought to link it to a bracelet ring necklace or pair of earrings but it could very well be the effect of your ...

Colloidal gold solutions having different particle sizes of 5−80 nm were applied on the surface of a yttria-stabilized zirconia (YSZ) plate, followed by drying at 50 °C and subsequent annealing at ...

Gold-bonding wires have been frequently used in connecting semiconductor devices and microstrip lines. This paper presents a design of transition between microstrip line and semiconductor device with ...

Short-wave infrared (SWIR) range carries information vital for augmented vision. Colloidal quantum dots (CQD) enable monolithic integration with small pixel pitch, large resolution and tunable cut-off ...
