In recent years, colloidal metal particles—especially gold and silver nanoparticles—have emerged as critical components in ...

Time-dependent in situ second harmonic generation (SHG) spectroscopy coupled with extinction spectroscopy is used to monitor the growth dynamics involved in the synthesis of colloidal gold–silver–gold ...

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 ...

Rapid and sensitive chemical sensing using microfluidic device equipped with sterically-bulky three-dimensional gold nanostructure (Au3D) was demonstrated. Au3D was expected as surface enhanced Raman ...

Govt tightens gold and silver import rules, moving mixed-metal and colloidal forms to the restricted list to curb duty evasion. Imports now need DGFT approval. The move follows rising concerns ...

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

Luckily, these 12 products are recommended by thousands of Amazon reviewers and may help alleviate some discomfort, or simply ...
