Summary: The efficiency of Rhodotorula mucilaginosa 1S1 as an Ag(I) biosorbent and its ability to biosynthesize recoverable silver nanoparticles have been evaluated. The process follows pseudo second-order kinetics and the Freundlich model, while optimal operational conditions are determined at 27 degrees C. Thermodynamic analysis shows positive values for enthalpy and entropy, indicating a spontaneous process, and a negative value for Gibbs free energy. The biomass exhibits a maximum biosorption capacity at 19 degrees C, and is capable of synthesizing silver nanoparticles with sizes between 12 nm and 20 nm.

Summary: This work focuses on optimizing the geometrical parameters of MoS2-Au to efficiently excite surface plasmons polaritons and increase the efficiency of plasmonic-based photovoltaic cells. The impact of Au nano-grating on light absorption using the plasmonic effect of noble metals is investigated. A simple geometry is proposed to enhance the coupling efficiency between MoS2 and Au thin film by varying slit widths and material thickness while keeping the periodicity constant. Efficient SPP excitation occurs at specific slit widths and resonance wavelengths have been observed.
