Hummingbird Scientific in‑situ holders are built to characterize quantum materials under electrical bias or magnetic field, enabling real-time observation of nanoscale transformations and the direct connection of observed mechanisms to performance. Operando biasing TEM experiments can be carried out at a range of temperatures from -170 °C to beyond 1000°C without need for drift correction, using ultra‑stable microfabricated chips. Every Hummingbird holder is developed for performance, reproducibility, and ease of use. Scroll down to explore the types of experiments with quantum materials made possible by these holders.
Studying catalytic mechanisms requires understanding how materials behave during reactions, where structure, chemistry, and performance continuously evolve. These processes must be observed under realistic reaction environments, while conventional electron microscopy is often limited to pre- or post-reaction analysis, making it difficult to capture these dynamic processes.
In-situ and operando TEM enable direct observation under working conditions. Hummingbird Scientific extends this capability with stable imaging across gas, liquid, and electrochemical environments, and experiments at up to 2 bar and above 1000 °C, allowing catalysts to be studied under realistic conditions with high reproducibility.
Observe catalyst restructuring, degradation, and active-site evolution during reactions under operando conditions, overcoming the limitations of post-reaction analysis and enabling direct identification of activity and deactivation mechanisms.
Correlate nanoscale structure with catalytic activity and selectivity during reactions, linking morphology, composition, and oxidation state directly to performance, which are otherwise difficult to resolve without real-time observation.
Study catalysts under controlled gas and liquid environments at elevated temperatures with stable imaging performance, ensuring behavior can be observed under realistic conditions rather than approximated.
Capture dynamic structural and chemical changes during reactions, including restructuring, phase transformations, and active-site evolution, which are often not accessible through static or ex-situ analysis.
Our applications scientists can help identify the right products, experimental workflows, and published examples for your research.
