Atomic Structure: Sub-Atomic Particles⚛️- GCS...

This episode details the key ingredients in fertilisers: nitrogen, phosphorus, and potassium. It outlines the chemical production of nitrogen-based fertilisers, specifically ammonium nitrate, highlighting its rich nitrogen content due to its dual sources. We explain that phosphat ...  Show more

In this episode, we look at plants and nitrogen.Plants require nitrogen to produce proteins necessary for growth. While the atmosphere is full of nitrogen gas, plants cannot directly utilise this form. Instead, they absorb soluble nitrates from the soil. Crop harvesting depletes ...  Show more

Melvyn Bragg and guests discuss an atomic particle that's become inseparable from modernity. JJ Thomson discovered the electron 125 years ago, so revealing that atoms, supposedly the smallest things, were made of even smaller things. He pictured them inside an atomic ball like a ...  Show more

In this episode, Jamie explores the fascinating world of prokaryotic cells, focusing on their unique features such as plasmids, the absence of mitochondria and chloroplasts, and their distinctive way of storing genetic material.

This discussion is particularly valuable ...

In this episode, we’ll explore the distinct characteristics of prokaryotic cells and what sets them apart from more complex cell types. We’ll discuss the presence of plasmids—small DNA rings that enable genetic information exchange. We’ll examine how prokaryotic cells lack mem ...

In this episode of MCAT Basics, we’ll cover Electrochemistry. We start with the role of salt bridges in electrochemical cells and cover the intricacies of cell notation. We’ll also discuss how ions maintain charge balance, the importance of reduction and oxidation potentials, ...
