Metal-bearing solid wastes are an important secondary source of metals. Compared to
mining from ores, the recovery of metals, especially precious metals from rich secondary …

In the past two decades, the use of biomolecules, either from biological or biomimetic
systems (or so-called biological or biomimetic synthesis), has emerged as a promising …

A facile one-pot eco-friendly process for synthesis of gold nanoparticles (AuNPs) with high
catalytic activity was achieved using cell-free extracts of Aspergillus sp. WL-Au as reducing …

Bacteria in natural and artificial environments often reside in self-organized, integrated
communities known as biofilms. Biofilms are highly structured entities consisting of bacterial …

With a projected steady decline of gold ore grade in mineral resources, mining applications
enabling efficient metal extraction from low-grade ores are of increasing interest to the …

Biomineralization is a process in which organic matter and inorganic matter combine with
each other under the regulation of living organisms. Because of the biomineralization …

The uptake of precious metals from electronic waste is of environmental significance and
potential commercial value. A facile bioreductive synthesis is described for Au nanoparticles …

Since biofilms are an important issue in the fields of medicine and health, several recent
microbiological studies have focused on their formation and their contribution to toxic …

In an era of electronics, recovering the precious metal such as gold from ever increasing
piles of electronic-wastes and metal-ion infested soil has become one of the prime concerns …

Biogeochemical processes are known to drive the cycling of gold via dissolution/re-
precipitation reactions that result in the transformation of gold grain in near-surface …
