How Does a Solar Cell Work?

June 25, 2019July 20, 2020 Sai RachakondaLeave a comment

A Solar Cell or Photovoltaic Cell (PV cell) in the most basic definition absorbs the sun's light and converts into electrical energy. In this post, we explore an in-depth description of the function of a PV cell. Understanding this mechanism is important as this field is rapidly advancing, producing much smaller and more efficient PV [...]

The Times When the Earth Froze Over

June 24, 2019July 20, 2020 Sai RachakondaLeave a comment

Hey guys, in ironic celebration of the start of Summer, we are going to cover the few periods of Earth's vast geologic history where we had an Ice Age so strong, it froze the world over. There are few times that the Earth completely or nearly froze over. The first was the Huronian glaciation which [...]

Electron Transport Chain and Chemiosmosis

January 9, 2019January 9, 2019 Sai RachakondaLeave a comment

The Electron Transport Chain and Chemiosmosis is where the vast majority of the ATP is synthesized. This is what makes Aerobic Respiration far more efficient per glucose than Anaerobic Respiration. Lets Review: So far in Glycolysis, Acetyl CoA step, and Krebs we have made 4 ATP, 10 NADH + H+ , and 2 FADH2. Note [...]
