Instrumentation
Level 1: State-of-the-art instrument
Projects owned or planned by NORTEM research groups, include
competence and technique development.
External users will not generally operate these instruments.
Level 2: Advanced instrument
Operators with agreed needs get access after
sufficient training and skills. Formalized training
maintains quality and ensures effective use.
Level 3: Standardized and routine TEM
Many users require hands-on access to perform simple tasks, where
analysis is routine or TEM is a minor activity in a project.
Once a specific task is approved, users can be trained.

Hummingbird
Hummingbird's Atmospheric Gas Flow TEM Holder
allows in-situ observation of the interaction of
materials with a gaseous environment under relevant
conditions. The effect of gaseous overpressure on the
physical properties of a material can be observed in real
time during an experiment. High resolution imaging of
active catalystic nano-particles will provide a deeper
understanding of these materials.

Biomedical & Biological Imaging
Hummingbird Scientific's continuous-flow TEM fluid holder initiates new groundbreaking capabilities to interrogate and image
biological processes using TEM by enabling dynamic imaging of biological materials in their native liquid environments. This
includes fundamental sequence, structure and function studies, as well as single-cell targeting, micro/nanobubble studies, and
insight into in vitro constitution and protein recombination.
Fluidics
The combined usage of TEM and nanomarkers allows direct observation and particle
tracking inside fluid flows with resolutions up to 1 nm which will ultimately lead to
elucidation of questions concerning boundary layer studies and particle velocimetry.
Materials and Chemical Science
Imaging nanostructures in liquid environments enables an increased
understanding of nano-particle synthesis and assembly. Additionally,
corrosion processes and catalytic reactions can be studied.
Energy Conversion Processes
Hummingbird Scientific's liquid holder enables in-situ imaging of electrochemical
reactions in fuel cells and batteries as they are occurring.
