NANOMATERIAL SYNTHESIS RESEARCH

Understanding the pathways that generate new nanomaterials will support the development of more efficient and safer technologies for areas like drug delivery, catalysis, cosmetics, and more. With Protochips’ workflow-based in situ TEM solutions, you can utilize the electron microscope to directly observe the fundamental pathways that control a material’s growth, interactions, and stability, providing a more efficient avenue for materials development.

SYNTHESIS AND GROWTH IN LIQUID MEDIA – POSEIDON AX

Apply temperature or mix liquids to initiate and observe synthesis

Observe the nucleation and growth of different materials in aqueous or organic media to understand structure and morphological information. Perform mixing of reactants to initiate growth with Poseidon AX or apply extreme hot or cold temperatures with Triton AX.

SYNTHESIS AT HIGH TEMPERATURES AND/OR ELECTRICAL BIAS – FUSION AX

Utilize high temperatures and/or electrical bias to initiate material growth in the vacuum of the TEM

Observe changes in structure, morphology, and chemistry as materials grow/change while the temperature is cycled, a voltage or current is applied, or electrical bias is applied at a specific temperature.

THE PROTOCHIPS PHILOSOPHY

Each Protochips in situ TEM solution has been designed with three key goals in mind to ensure relevance of the results in a timely fashion.

Scaling Bulk to Nano

Flexibility in creating a native environment, whether it requires gases and humidity, low or high temperatures, or organic solvents, provides the most meaningful results

Accelerating Productivity

Innovative designs and machine vision software lower the learning curve and streamline data collection and analysis

Fostering Collaboration and Discovery

Intuitive data processing platform provides transparency for collaborators, with a new way to visualize data for more productive discussions
