Sep 20, 2023 (Nanowerk News) Researchers have developed a method of “wiring up” graphene nanoribbons (GNRs), a class of one-dimensional materials that are of interest in the scaling of microelectronic devices. Using a direct-write scanning tunneling microscopy (STM) based process, the nanometer-scale metal contacts were fabricated on individual GNRs and...
New Mars gravity analysis improves understanding of possible ancient ocean
Sep 20, 2023 (Nanowerk News) The first use of a novel method of analyzing Mars’ gravitational force supports the idea that the planet once had an extensive northern ocean. In doing so, the method defines the scope of what scientists refer to as the northern Martian paleo-ocean in more detail....
The missing link to make easy protein sequencing possible?
Sep 20, 2023 (Nanowerk News) There has been a real race among scientists to create a technology that enables easy protein sequencing. Professor of Chemical Biology Giovanni Maglia of the University of Groningen has now found the missing piece in the puzzle: a way to transport a protein through a...
