Project Background

X-ray fluorescence spectroscopy (XRF) has emerged as a vital tool for elemental analysis, continuously driving groundbreaking advances in fields such as new energy, semiconductors, and geosciences. As scientific research deepens, scientists are moving beyond static observations at ambient temperatures, seeking instead to capture the dynamic evolution of material compositions in temperature‑controlled environments in real time, thereby unveiling more profound underlying mechanisms.

To meet this cutting-edge demand, we successfully customized a high-performance temperature‑controlled hot/cold stage for a research group at King Abdullah University of Science and Technology (KAUST). This device is not only a precision temperature‑control tool but also an essential platform that helps researchers expand the frontiers of knowledge and advance the development of in situ characterization techniques under variable temperatures.
