[BS4] Researches at Large-Scale Facilities
- Wonhyuk Jo (European X-ray Free-Electron Laser Facility)
Description
The primary role of researchers is exploring a fundamental mechanism of nature including the universe, materials, biology, and so forth. Most researcher conduct laboratory-based researches, and sometimes they face technical challenges. To overcome these challenges, various kinds of large-scale experimental facilities have been developed all over the world for a long time, which can provide advanced experimental methods utilizing particle accelerators, muon and neutron generators, etc. In this session, we introduce the various scientific studies conducted at large-scale facilities and discuss the impact that large-scale facilities will have on the scientific community in the future.
Organometallic perovskite solar cell has been considered as one of the most attractive and promising next generation solar cells due to its superior photoelectric properties including low-cost fabrication potential based on solution process After Miyasaka's report of 3.9% power conversion efficiency (PCE) in 2009, it has developed rapidly and reached a highest PCE of 26.02% by Seok in 2023. In...
The I08-1 soft X-ray ptychography instrument at the Diamond Light Source (UK) is a facility dedicated to the spectro-microscopic and tomographic analysis of the interaction of organic and inorganic matter with unprecedented spatial resolution. It provides capabilities to do Near Edge X-ray Absorption Fine Structure (NEXAFS) spectroscopy for the analysis of transition metals or other elements...
Fusion technology, capable of converting energy caused by nuclear-fusion reactions into usable energy, has been widely acknowledged as a potential solution to the global energy crisis and a carbon-neutral future. One of the chief challenges in exploiting fusion reactions is plasma stabilization under extreme temperature, a considerable hurdle that must be overcome [1-3]. The Korea...
Controlling the magnetization direction of a ferromagnet is crucial for magnetic memories, including cassette tapes, hard disk drives, and the next-generation magnetoresistive random access memory (MRAM)—a type of non-volatile memory that stores data by manipulating magnetic states. However, the current method of controlling magnetization—by generating a spin current converted to charge...
Surface modification and doping of hematite nanorods (NRs) for enhanced photoelectrochemical (PEC) water splitting was developed using a sputtering method. The ZrOx/β-FeOOH NRs were fabricated by the Zr sputter deposition and its amount was controlled by sputter time. The NRs were followed by 800 ◦C quenching to develop Zr-Fe2O3 nano-photoanodes and the nanorods were vertically oriented along...
