Article Synopsis
- The study introduces a simple and low-temperature method (60 °C) to synthesize environmentally friendly silver-gold-sulfur (AgAuS) nanocrystal solar cells, overcoming the complexity and high temperatures of previous methods.
- The AgAuS nanocrystals show broad absorption spectra and high extinction coefficients, making them suitable for use in solar cells.
- By utilizing a hybrid mixture at the interface of the solar cells, the research achieves a power conversion efficiency of 3.38%, illustrating the potential of AgAuS nanocrystals in clean energy technology.
A minimally-disruptive portable electrochemical system is constructed by combining a hand-held syringe as reservoir with disposable screen-printed electrodes (SPEs) modified with a simple and efficient yeast/CoO/Au material for lead determination by a square-wave voltammetry (SWV) method. Not only can it preserve the operation and advantages of the conventional electrochemical procedure, but it also integrates sampling, filtering and analysis to make the determination of lead convenient and effective at higher and lower concentration levels. This is the first report of a microbial biosensor based on active yeast crosslinked to CoO/Au particles using glutaraldehyde as the crosslinking agent.
