Wildfire Application Fields
Get more from your TEM, 3 reasons to choose for Wildfire
Investigating materials while changing temperature expands the application space of conventional TEM and enhances its already powerful imaging capabilities. The Wildfire system allows for researchers to heat from room temperature to 1,300 °C with the ultimate temperature control and ultimate sample stability in all directions. The stability of the Wildfire system ensures that the full resolution and analytical performance of every TEM can be maintained while observing sample dynamics at elevated temperature.
Experiment: Thermal degradation of perovskite solar cell
Heat-induced degradation of perovskite solar cells. G. Divitini, et al. University of Cambridge Nature Energy 2016. DOI: 10.1038/nenergy.2015.12
Real time dynamics
Behavior at the macroscale is strongly linked to atomic arrangement and its transformation. In this example Ru nanoparticles supported on silica are heated to 1300 °C using a DENSsolutions Wildfire system. At that temperatures, the SiO2 sphere evaporates and the Ru nanoparticles become very mobile. The emphasized nanoparticle changes from round to square. This shape change can be studied in detail, due to technology behind DENSsolutions heating systems which ensures high sample stability, sub-Å resolution and therefore enables deeper understanding of the processes involved,

High temperature EDS
Chemical analysis while heating is extremely important to understand the dynamics of temperature-induced transformations High quality EDS analysis at elevated temperatures is challenging due to the intense generation of infrared radiation during heating which disturbs the X-Ray spectral acquisition. DENSsolutions provides the technology and the experimental evidence thatin situ EDS at elevated temperatures is reliable and robust technique across a large temperature range. For the first time it was shown that EDS analysis is possible even at 1000 °C.

Sample carrier for real-time thermal studies
The Nano-Chip is the heart of the Wildfire system and allows fast heating and quenching with the ultimate three dimensional stability. The 4-point-probe method enables local measurament of the temperature with fast feedback for immediate stabilization and accurate temperature.
Bringing the ‘in situ’ to your TEM
The Wildfire range of Sample Holders is optimised for specific application areas of research. Options include alpha tilt range up to 70° and beta tilt range up to 25°. All systems share EDS optimised design and a hassle free Nano-Chip loading.
A seamless integrated system for total control
The new Impulse software provides the user with full control
over sample’s temperature. It enables faster experimental setup, easy customization of the workspace and easy monitoring of the experiment.
Gatan GMS3 Integration
Synchronised stimulus & data for easier analysis
DENSsolutions & Gatan have partnered to integrate the Wildfire system with the GMS3 software package creating the Wildfire In Situ Plug-in. Optimised for in situ TEM experiments, the integrated plug-in provides researchers with total control over the in situ stimuli, camera settings, images and more!
Some great work from our customers:
Frequently Asked Questions
What is the tilt range of the Wildfire system?
What is the best achievable resolution at elevated temperature?
The resolution of 0.6 Å can routinely be achieved at 1000 °C. The resolution is dependent on your TEM; however, the achievable resolution at elevated temperature will be as good as for your standard TEM holder.
What is the temperature range for the Wildfire system?
Is Wildfire compatible with EDX?
Can a Wildfire system be used for biasing experiments?
