POSTECH and Korea Institute of Materials Science joint research team develops an AI-based technique that improves the quality of SEM images that requires no human oversight.
In a new study in Optica, The Optical Society s journal for high impact research, researchers show that the fiber optic cables that carry data across the world s oceans can also be used to sense geophysical events and monitor ocean and seafloor conditions.
Prof. HUANG Qing s group from the Hefei Institutes of Physical Science (HFIPS) developed a surface-enhanced Raman spectroscopy (SERS) gas sensor to detect aldehyde with high sensitivity and selectivity, which provided a new detection method for studying the adsorption of gas molecules on porous materials. The relevant research results have been published in Analytical Chemistry.
Recently, a research group led by CHU Yannan and HUANG Chaoqun from the Institute of Health & Medical Technology of the Hefei Institutes of Physical Science (HFIPS) developed an effective method for on-site detection of methamphetamine (MA) in the presence of nicotine by a homemade ion mobility spectrometry. Relevant results were published in Analytical and Bioanalytical Chemistry.

An exploratory investigation into the behavior of materials with desirable electric properties resulted in the discovery of a structural phase of two-dimensional (2D) materials. The new family of materials are electrides, wherein electrons occupy a space usually reserved for atoms or ions instead of orbiting the nucleus of an atom or ion. The stable, low-energy, tunable materials could have potential applications in nanotechnologies.
