The extension of the light absorption of photovoltaics into the near-infrared region is important to increase the energy conversion efficiency. Although the progress of the lead halide perovskite solar cells is remarkable, and high conversion efficiency of >20% has been reached, their absorption limit on the long-wavelength side is ∼800 nm. To further enhance the conversion efficiency of perovs...

Objective(s): A novel technique for the early diagnosis of breast cancer involves the use of nanoparticles (NPs). The present study aimed to use gold NPs to assess the variations in light source transfer intensity. Materials and Methods: Blood samples with hemoglobin (Hb) concentrations of ×1, ×2, and ×4 were used to simulate normal and cancerous conditions in the breast. Spherical gold N...
