In this episode, we will discuss the alveoli in the circulatory system.Alveoli are microscopic air sacs within the lungs where the crucial exchange of oxygen and carbon dioxide occurs between air and blood through diffusion. Their structure is highly adapted for this vital proces ...  Show more

In this episode, we look at transportation in cells. We will explain how substances move into and out of cells, highlighting three key mechanisms. Diffusion is described as the movement of particles from high to low concentration areas. Osmosis is presented as a specific type of ...  Show more

In this episode, we discuss the concept of electron structure, focusing on how electrons are organised within atomic shells and energy levels. Learn about the order in which electrons fill these shells and what determines their configuration.

In this episode, we discuss fullerenes, which are a class of carbon molecules forming hollow structures, often with hexagonal rings alongside pentagonal or heptagonal ones.

The initial discovery, buckminsterfullerene (C60), is a spherical fuller ...

In this episode, we delve into the history of the periodic table, exploring the contributions of John Newlands and Dmitri Mendeleev. Discover how the table evolved from organising elements by mass to its modern form based on atomic numbers.
