The dinitrogen molecule, which was first identified in the late 18th century, owes its extreme stability to its triple bond. Therefore, whereas atoms like carbon can exist in multiple allotropes, no ...

Now chemists at Justus Liebig University Giessen have created and isolated the neutral nitrogen allotrope hexanitrogen, or N6—a string of six nitrogen atoms held together by four double bonds ...

In a study described in Nature Chemistry, researchers overcame this problem by using three-letter "triplet" RNA building blocks in water and adding acid and heat, which separated the double helix.

A team headed by Prof Armido Studer (University of Münster/Germany) has presented a new, efficient method for incorporating nitrogen into organic molecules. This method could be of interest ...

For refrigerant heating and cooling systems to work correctly and optimally, the refrigerant must be free of air, nitrogen, moisture, and contaminants. Therefore, before charging a system, it’s ...

During semiconductor manufacturing, the high temperature sulfuric acid peroxide mixture (SPM) and airborne molecule contaminants (AMCs) can result in the formation of defects such as Silicon-carbide ...

Historical paintings are also complex chemical objects so museums turn to analytical chemistry to decipher the mysteries concealed within their micrometric paint layers. Recently, x ray and infrared ...
