What is Aduro?
Aduro is the Heating/Electrical Testing TEM holder made by Protochips to perform in situ experiments in the TEM and allows for dynamic observation of nano-scale processes. With the Aduro you can insert your sample and create a heating schedule such as ramp and soak or cycle between temperatures up to a maximum of 1200C. During this heating the Aduro can record electrical measurements such as resistivity, I-V curves, etc., with electrical biasing up to 750mA and up to 50V. The Aduro does this by both a uniquely designed holder and sample stage design. The experiment is captured as a movie after which individual frames can be exported. Alternately, the experiment can be halted at certain intervals to acquire images.
If the samples are particulate suspended in a fluid, a sample can be simply dropped onto the center of the chip. Once the liquid is allowed to evaporate, the sample can be placed in the TEM and the experiment can be performed. Bulk specimen require a FIB cut and then are placed on the center of the chip. Conductive straps of Pt can then be deposited to connect the electrical leads or to hold the sample in place as the experiment is carried out.
