Metallic nanoparticles are widely used in applications such as catalysis, sensing, imaging, and drug delivery. Quantum dots are composed of semiconductor materials, such as cadmium selenide (CdSe), ...

The photosensor is a simple cadmium sulfide cell, which measures the intensity of light bouncing back from an object as an Arduino drives the LED through all possible colors with PWM signals.

Silver bismuth sulfide (AgBiS 2) nanocrystals (NCs) are an earth-abundant material that has been used in recent years as a promising PV material, often in combination with cadmium sulfide in the ...
