Insight Chips is dedicated to making liquid-cell TEM research more quantifiable.

While it's fascinating in itself to observe how substances grow, dissolve, or move at nanoscale in liquid environments, the scientific goal is ultimately to precisely determine the extent of these changes and the conditions under which they occur.

‍Seoul National University's Prof. Jungwon Park and his team — Sungsu Kang, Ph.D., Minyoung Lee, and Hayeon Baek—are working on such crucial research with our Nano Channel Chips.

They are investigating the dissolution rates of Pd crystals under the electron beam, examining how these rates correlate with the electron dose rate, and exploring the impact of liquid thickness and the surface properties of the liquid cell on radiolysis.

With our Nano Channel Chips, Prof. Park's team can precisely rely on a well-known, uniform liquid thickness of each chip and compare 2 surfaces: One coated with ~3 nm of Al2O3 on SiN, and another being only SiN.

We look forward to seeing their work in a publication soon.In the meantime, here are some of the preliminary results from the TEM, showing the disslolution of the Pd nano particles.
