Atomic-scale semiconductor process technology and clean hydrogen technology join hands
To enhance this efficiency, there is a requirement to fabricate electrodes with a porous structure. Unfortunately, existing technologies face challenges in achieving a uniform coating of ceramic materials within electrodes possessing intricate porous structures.
A collaborative research team, comprising Professor Jihwan An and Ph.D. candidate Sung Eun Jo from the Department of Mechanical Engineering at Pohang University of Science and Technology (POSTECH), and others, has successfully produced porous electrodes for SOFCs using latest semiconductor processes. This research has been featured as a back cover article in Small Methods.
The process of atomic layer deposition (ALD) involves depositing gaseous materials onto a substrate surface in thin, uniform atomic layers. In a recent study, Professor Jihwan An’s team, known for their prior work in enhancing the efficiency of SOFCs using ALD, developed and applied a powder ALD process and equipment. This enabled them to precisely coat nano-thin films on fine powders.
NASA’s New Asteroid Sample Is Already Rewriting Solar System History
Scientists have scarcely begun studying pristine material from asteroid Bennu brought back to Earth by the OSIRIS-REx mission, but have already found several surprises.
New topological metamaterial amplifies sound waves exponentially
Researchers at AMOLF, in collaboration with partners from Germany, Switzerland, and Austria, have realized a new type of metamaterial through which sound waves flow in an unprecedented fashion. It provides a novel form of amplification of mechanical vibrations, which has the potential to improve sensor technology and information processing devices.
