Home Physics Big Achievement: First-Ever Capture of X-ray Image of a Single Atom

In a groundbreaking accomplishment set to reshape scientific exploration, a team of researchers has achieved an extraordinary feat: capturing the X-ray signature of a single atom. Spearheaded by Saw Wai Hla, a distinguished Professor of Physics at Ohio University and a scientist at Argonne National Laboratory, this achievement represents a remarkable leap forward in our understanding and manipulation of matter at its most fundamental level. The Evolution of X-ray Technology Since Wilhelm Roentgen's discovery of X-rays in 1895, this form of electromagnetic radiation has wielded transformative influence across numerous domains, from medicine to space exploration. Yet, despite decades of advancement, a significant challenge persisted: the inability to detect the X-ray signal of individual atoms. Traditional X-ray detectors lacked the sensitivity required to register the faint emissions from solitary atoms, prompting the need for innovative methodologies and technologies. How One Atom Changes Everything For scientists like Hla, the aspiration to X-ray a solitary atom has long been a tantalizing goal. With this groundbreaking achievement, researchers can now not only visualize individual atoms with unparalleled precision but also discern their composition and chemical state. This capability unlocks a multitude of possibilities, from revolutionizing environmental and medical research to opening up new avenues in materials science and beyond. This big achievement was made possible through the ingenious application of synchrotron X-ray scanning tunneling microscopy (SX-STM), an advanced technique that combines traditional X-ray detectors with specialized instruments capable of detecting X-ray excited electrons. By positioning a sharp metal tip in extremely close proximity to the sample, researchers succeeded in capturing the elusive X-ray image of a single atom, heralding a new era of exploration at the atomic scale. Decade of Collaboration Culminates in Success The journey toward capturing the X-ray signature of a single atom was filled with challenges. Over the course of twelve years, Hla and his team, in collaboration with scientists at Argonne National Laboratory, meticulously developed and refined the necessary techniques, ultimately achieving this remarkable feat. Their unwavering dedication and perseverance have resulted in a breakthrough poised to shape the trajectory of scientific inquiry for years to come.

The researchers found that between 2010 and 2020, "heat blobs" formed over the northeast Pacific, increasing ocean temperatures by up to 1.8 degrees Fahrenheit from the Bering Strait to the Gulf of Alaska. This warming has had severe ecological effects, including massive fish die-offs, toxic algae blooms, and the disappearance of whales. The study's findings point to China's significant reduction of aerosol emissions, which has been a major factor in these heat waves. Aerosols, typically produced from industrial activity, act as a cooling agent by reflecting the sun's heat back into space. By reducing these pollutants, China has inadvertently allowed more heat to be absorbed, leading to increased atmospheric pressure and higher temperatures. Researchers warn that without a reevaluation of aerosol policies, these heat waves and their consequences could worsen.
