German BESSY II Research Reveals: Cesium Chloride Seed Layer Can Improve Quality of Perovskite-Silicon Tandem Solar Cells
A team from the Helmholtz-Zentrum Berlin (HZB) in Germany used the BESSY II synchrotron radiation facility to conduct nanoscale analysis of perovskite-silicon tandem solar cells fabricated by evaporation methods, and proposed a new approach to improve the quality of perovskite thin films. The study shows that introducing a thin cesium chloride (CsCl) seed layer between the two sub-cells promotes uniform growth of the perovskite layer while reducing undesirable lead iodide deposition at the interface. The research demonstrates that the cesium chloride seed layer improves the growth of the evaporated perovskite layer and reduces the formation of lead iodide. Scanning electron microscopy images show that the perovskite layer grown without a seed layer (left image) consists of extremely fine crystallites...

Tohoku University and Rigaku Establish Joint Research Institute for X-ray Metrology
Tohoku University and Rigaku Corporation, a subsidiary of Rigaku Holdings Group, recently announced that they established the "Rigaku-Tohoku University X-ray Metrology Co-Creation Research Institute Beyond The Limits" on August 1, 2026, and commenced joint research. The institute will operate for a period of three years, until July 31, 2029, with the possibility of extension based on research outcomes. According to the announcement, the new institute will focus on upgrading X-ray metrology technologies, establishing new measurement methods, and nurturing the next generation of researchers. As semiconductor devices continue to shrink in size while becoming increasingly multi-layered and multi-material in composition, manufacturing processes are growing more complex, driving rising demand for high-precision, non-destructive evaluation of materials and structures. Existing measurement methods face limitations in evaluating fine structures and precisely analyzing depth-direction structures, making the development of new approaches such as soft X-ray techniques an important direction.

Canadian Light Source Synchrotron at University of Saskatchewan Receives $3 Million CAD in Upgrade Funding
On August 26, Innovation Saskatchewan announced that it will provide $3 million CAD in funding to the Canadian Light Source synchrotron at the University of Saskatchewan to support the installation of an advanced solid-state amplifier, advancing the facility's upgrade efforts. According to reports, this solid-state amplifier is a key component of the Canadian Light Source's core particle accelerator and will support the operation of its 22 synchrotron radiation beamlines. The upgrade is expected to enhance facility performance, operational reliability, and energy efficiency, further strengthening its capacity for cutting-edge scientific research. The Canadian Light Source is Canada's only synchrotron facility. Synchrotrons use electromagnetic fields and radiofrequency waves to accelerate electrons to near the speed of light, keeping them in a circular orbit; as electrons move, they generate high-brightness, highly focused synchrotron radiation beams, which are directed to different experimental beamlines to help researchers study material structures and properties at the atomic scale.

Electron Beam Processing Can Reduce Poultry Pathogens, Study Shows Turkey Meat Quality Remains Well Preserved
A study on electron beam treatment of poultry meat products shows that electron beam irradiation has the potential to reduce the risk of foodborne pathogens in poultry while preserving meat quality as much as possible. The paper, titled "Effects of Electron Beam (eBeam) Treatment on the Texture and Sensory Attributes of Chicken and Turkey Meat Batters," was published in the journal Poultry Science. Electron beam is a non-thermal processing technology that uses high-energy electrons to cause irreversible damage to pathogen DNA or RNA, making it difficult for bacteria to replicate. Like X-rays and gamma rays, electron beam has been approved by the U.S. Food and Drug Administration for cold pasteurization that does not rely on heating. The research team used the electron beam irradiation facility at Texas A&M University...

Korea's Gil Medical Center Expands Application of Markerless Surface-Guided Radiation Therapy
Gachon University Gil Medical Center in South Korea announced on August 26 that it is expanding the clinical application of markerless surface-guided radiation therapy (SGRT) to enhance the precision and comfort of radiation therapy for cancer patients. According to the hospital, the proportion of markerless SGRT in its radiation therapy procedures has increased from 28% in the first half of 2025 to 37% in the first half of 2026. This change indicates that this treatment-assistive technology, which reduces the burden of skin marking on patients, is gaining broader clinical adoption. Markerless SGRT is an advanced technique used for patient positioning and monitoring during radiation therapy. Unlike conventional methods, patients do not need to retain target line markings on their skin; the treatment system can assist in confirming patient positioning through surface guidance, enabling radiation to be delivered more accurately to the target area.

IAEA Study: Five-Star Rating System Can Improve CT Imaging Safety and Reduce Unnecessary Radiation Exposure
A new study led by the International Atomic Energy Agency (IAEA) in collaboration with Massachusetts General Hospital and Harvard Medical School in Boston, USA, shows that a five-star rating system can help hospitals optimize image quality, reduce radiation dose, and decrease unnecessary patient radiation exposure in computed tomography (CT) examinations. The study has been published in the European Journal of Radiology. CT imaging uses X-rays to obtain detailed images of internal body structures and is an important tool in diagnosing a wide range of diseases. The study notes that CT image quality is closely related to radiation dose—higher doses typically reduce image noise and improve clarity, but do not always yield additional diagnostic value. How to minimize radiation exposure while ensuring diagnostic accuracy is key to optimizing CT examination protocols.
