Taatjes said one of the questions remaining after the first direct measurement of Criegee reactions was whether the remarkably fast reaction of CH2OO with SO2 was representative of other Criegee ...

Sand topdressing application rates are recorded and easily referenced for future applications. This method can be used to accurately measure rates for routine topdressing applications or for heavy ...

There are a number of ways to investigate the rate of a reaction in Chemistry. This is an outline of the required steps to undertake one of these methods. It is important in this core practical to ...

Silicon-based microscales allow real-time measurements of the growth rate of single cells and open up interesting perspectives for the study of mass biogenesis at the cellular level.

A catalyst does not actually become part of the products of the reaction. Summary Students watch a video and do a quick activity to see that a catalyst can increase the rate of the breakdown ...

How aggressive is a tumor? To measure the tumor status without taking tissue samples, Italian researchers have developed a method based on magnetic resonance imaging (MRI) of whole body parts. The ...
