Thin layer protects battery, allows cold charging

In the search for a reliable, quick-charging, cold-weather battery for automobiles, a self-assembling, thin layer of electrochemically active molecules may be the solution, according to a team or researchers.

Artificial materials for more efficient electronics

The discovery of an unprecedented physical effect in a new artificial material marks a significant milestone in the lengthy process of developing "made-to-order" materials and more energy-efficient electronics.

Researchers show how to make non-magnetic materials magnetic

A complex process can modify non-magnetic oxide materials in such a way to make them magnetic. The basis for this new phenomenon is controlled layer-by-layer growth of each material. An international research team with researchers ...

New chemistry for ultra-thin gas sensors

The application of zinc oxide layers in industry is manifold and ranges from the protection of degradable goods to the detection of toxic nitrogen oxide gas. Such layers can be deposited by atomic layer deposition (ALD) which ...

Researchers find new shape for hydrophobic molecules in water

The embedding of hydrophobic molecules in water looks quite different than previously assumed. In water, hydrophobic molecules are surrounded by a two different water populations: the inner shell forms a two-dimensional network ...

Thin layer chromatography

Thin layer chromatography(TLC) is a chromatography technique used to separate mixtures. Thin layer chromatography is performed on a sheet of glass, plastic, or aluminum foil, which is coated with a thin layer of adsorbent material, usually silica gel, aluminium oxide, or cellulose. This layer of adsorbent is known as the stationary phase.

After the sample has been applied on the plate, a solvent or solvent mixture (known as the mobile phase) is drawn up the plate via capillary action. Because different analytes ascend the TLC plate at different rates, separation is achieved..

Thin layer chromatography finds many applications, including:

A number of enhancements can be made to the original method to automate some steps, to increase the resolution achieved with TLC and to allow more accurate quantitation. This method is referred to as HPTLC, or "high performance TLC".
