Abstract: The present invention relates to a method for selectively precipitating and extracting gold in aqueous solution by niacin. Aqueous Au3+ is precipitated selectively as it's complex from gold containing acidic mixtures by biomolecule niacin, with the formula [AuCl4]?[2Niacin+H]+.

The method is highly cost-effective, sustainable and recovers about 96.5% of gold in 2 minutes from an electronic waste composed of Au. Cu and Ni. The method is also employed to extract gold from nanomaterials waste generated in laboratories.

Abstract: Various kinds of oscillatory instabilities are seen in practical systems. We devise of way of combating these oscillatory instabilities in a thermoacoustic system. Confined combustion environments are prone to large amplitude pressure oscillations known as thermoacoustic instabilities. Although several techniques have been employed to control or mitigate such instabilities, optimization of these methods is achieved at the cost of performing multiple trial and error experiments/simulations. This invention develops a methodology to quantify the spatio-temporal dynamics using synchronization, recurrence, and fractal measures and find the coherent region in such turbulent flow field. Such an analysis provides us with a novel way to detect critical regions responsible for thermoacoustic instability, and other oscillatory instabilities in general, in the flow field and implement an optimized control strategy at these regions.
