Transcutaneous vaccination by means of coated and hollow microneedles
Transcutaneous vaccination is attractive because it is non- or minimally invasive, pain free and the site of administration (skin) is easily accessible. What’s more, transcutaneous immunization can lead to a strong immune response owing to the presence of immune-competent cells in the skin.

Adiabatic Energy Loss in Hyperthermal H Atom Collisions with Cu and Au: A Basis for Testing the Importance of Nonadiabatic Energy Loss
Nonadiabatic energy transfer from the translational motion (T) of a molecule impinging on metal surface to the metal’s electrons may determine whether the molecule can lose enough energy to adsorb or react.
