Place petri dish on stage of overhead projector. Pour water into dish to a depth of ¼” to 3/8” Scoop a small amount of Pb(NO3)2 into the water at one side of the dish. Scoop a small amount of KI into ...

The Nature Index 2026 Research Leaders reveal the leading institutions and countries/territories in the natural sciences, health sciences, applied sciences and social sciences, according to their ...

Lead iodide, also known as plumbous iodide, is a very rarely used compound semiconductor, which appears bright yellow at room temperature. Due to the high atomic numbers of its elements, it has a high ...

An international research team has fabricated a perovskite solar cell that reportedly shows lower non-radiative recombination and defect state density. “Our study introduces an innovative lead iodide ...

A 100mm petri dish containing water is placed on an overhead projector. When solid Pb(NO 3) 2 is place on one side and solid KI on the other, PbI2 precipitates in the center.

The recycled PbI2 microcrystals exhibit the quality and purity levels necessary for making photodetectors. The production of PbI2 microcrystals at a kilogram scale is shown.
