Transforming Flies Into Degradable Plastics

Imagine using insects as a source of chemicals to make plastics that can biodegrade later — with the help of that very same type of bug. That concept is closer to reality than you might expect.

How Is Ceviche "Cooked?"

What does it mean to have cooked something? Most people are probably thinking cooking involves a heat source to break down proteins. But what about ceviche? No heat is used to “cook” it but it still undergoes a process where proteins are denatured.

Discarded Aloe Peels Could Be a Sustainable, Natural Insecticide

Scientists report that aloe peels, often discarded as agricultural waste, can ward off bugs, acting as a natural insecticide. They have identified several bioactive compounds in extracts from the peels that deter insects from feasting on crops.
TKN analysis of environmental samples: soil and wastewater Kjeldahl nitrogen determination

TKN Analysis of Environmental Samples: Soil and Wastewater Kjeldahl Nitrogen Determination

In this video, we take a show TKN analysis, a critical method for determining total Kjeldahl nitrogen (TKN) in soil and wastewater samples.

TKN is a key indicator of the nitrogen content in environmental samples, providing critical information for monitoring and assessing environmental impacts. We demonstrate each step of the Kjeldahl method for TKN determination, which involves digestion, distillation and titration, and how it can be applied to both soil and wastewater samples.

Burning Forever Chemicals With Water

Forever chemicals are extremely useful in industry, but they can also leak into the environment, your drinking water and your blood. And they last (practically) forever. But now chemists have a new way to destroy them: burning them with water.
