scientists have been able to differentiate the chemical bonds in
individual molecules for the first time using a technique known as
noncontact atomic force microscopy (AFM). The results push the
exploration of using molecules and atoms at the smallest scale and could
be important for studying graphene devices, which are currently being
explored by both industry and academia for applications including
high-bandwidth wireless communication and electronic displays.

Scientists
have reached a record precision in radar distance measurements. With
the help of a new radar system, an accuracy of one micrometer was
achieved in joint measurements. The system is characterized by a high
precision and low cost. Potential applications lie in production and
plant technology.
