Radioactivity detection using very simple ionization chamber and a single J FET transistor

Radioactivity detection using very simple ionization chamber and a single J-FET transistor

Today I will show a very simple ionization chamber that can detect radioactivity. I was able to detect with it ionizing radiation from a smoke detector (Am241 isotope). It’s also immune to electromagnetic interference (EMI) due to a good shielding. This device doesn’t explicitly use any power supply. It’s connected to a multimeter set to measure resistance, […]

RESEARCHERS DEVELOP NEW HYBRID SOLAR PANEL THAT CAN GENERATE POWER FROM RAIN TOO

RESEARCHERS DEVELOP NEW HYBRID SOLAR PANEL THAT CAN GENERATE POWER FROM RAIN TOO

The researchers at Soochow University in China, have published a paper on the hybrid device that is able to harness the power of sun and rain using a hybrid panel. By attaching a transparent nanogenerator to a silicon solar cell, researchers have designed a device that harvests solar energy in sunny conditions and the mechanical energy of falling raindrops in rainy conditions. The dual
