Nitrogen purge of wafer carriers is driving defect density reduction at critical process steps. We discuss the mechanism of defect creation and how nitrogen purge improves defect density. We report on ...

Atomic chlorine (Cl) is a strong atmospheric oxidant that shortens the lifetimes of pollutants and methane in the springtime Arctic, where the molecular halogens Cl2 and BrCl are known Cl precursors.

Using nuclear magnetic resonance, researchers at ETH Zurich have studied the atomic environments of single platinum atoms in ...

Plastic products are widely used in daily life, leading to the pervasive presence of microplastics, which have posed great threats to human health. However, the relative lack of methods to observe the ...

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 ...

Handbook of A nalytical Chemistry is intended for scientific workers, and chemistry students in universities, polytechnics, and technical colleges. It can be used in solving various problems (both ...

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 ...
