In gel electrophoresis, the molecules to be separated are pushed by an electrical field through a gel that contains small pores. The molecules travel through the pores in the gel at a speed that ...

Exclusion chromatography can be used to separate molecules on the basis of size 1,2. The technique described here, which uses gel filtration to separate high-molecular-weight DNA from smaller ...

The sol-gel synthesis process begins with the preparation of a sol, where metal or metalloid precursors are dissolved in a solvent. These precursors undergo hydrolysis and polymerization reactions, ...

It is well-known that fire can be fought with fire — the principle behind backburning used to combat forest fires. However, ...

Professor Jonathan Steed Professor Steed is fascinated by the way in which chemical molecules assemble – like Lego blocks – to give complex, functional structures. Gel (and jelly), for example, ...

The gel will slowly rise in the cup. That’s what happened in the diaper to make all ... To answer these kinds of questions using chemistry, we have to think about the atoms and molecules that the ...

The proximity of molecules within the polymer promotes smoother electron transfer, resulting in higher quantum efficiency of photoinduced hydrogen generation in gel systems compared to ...
