    Professor Yan Yu's team at USTC utilized the CIQTEK Scanning Electron Microscope SEM3200 to study the post-cycling morphology. It developed amorphous carbon with controllable defects as a candidate material for an artificial interface layer balancing potassiophilicity and catalytic activity.   The research team prepared a series of carbon materials with different degrees of defects (designated as SC-X, where X represents the carbonization temperature) by regulating the carbonization temperature. The study found that SC-800 with excessive defects caused substantial electrolyte decomposition, resulting in an uneven SEI film and shortened cycle life. SC-2300, with the fewest defects, had insufficient affinity for potassium and easily induced potassium dendritic growth. SC-1600, which possessed a locally ordered carbon layer, exhibited an optimized defect structure, achieving the best balance between potassiophilicity and catalytic activity. It could regulate the electrolyte decomposition and form a dense and uniform SEI film.   The experimental results demonstrated that SC-1600@K exhibited long-term cycle stability for up to 2000 hours under a current density of 0.5 mA cm-2 and a capacity of 0.5 mAh cm-2. Even under higher current density (1 mA cm-2) and capacity (1 mAh cm-2), it maintained excellent electrochemical performance with stable cycles exceeding 1300 hours. In full-cell testing, when paired with a PTCDA positive electrode, it maintained 78% capacity retention after 1500 cycles at a current density of 1 A/g, demonstrating outstanding cycle stability.   This research, titled "Balancing Potassiophilicity and Catalytic Activity of Artificial Interface Layer for Dendrite-Free Sodium/Potassium Metal Batteries," was published in Advanced Materials. Figure 1: The microstructure analysis results of carbon samples (SC-800, SC-1600, and SC-2300) prepared at different carbonization temperatures are presented. Through techniques such as X-ray diffraction (XRD), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), and wide-angle X-ray scattering (WAXS), the crystal structure, defect level, and oxygen and nitrogen doping of these samples were analyzed. The results showed that as the carbonization temperature increased, the defects in the carbon materials gradually decreased, and the crystal structure became more orderly.   Figure 2: The current density distribution during potassium metal growth on different composite negative electrodes was analyzed using finite element simulation. The simulation results showed that the SC-1600@K composite electrode exhibited a uniform current distribution during potassium deposition, which helped suppress dendritic growth effectively. Additionally, the Young's modulus of the SEI layer was measured using atomic force microscopy (AFM), and the results showed that the SEI layer on the SC-1600@K electrode had a higher modulus, indicating its stronger firmness and...

The 7th International Conference of the Asian Union of Magnetic Societies (IcAUMS) will be held at the Okinawa Convention Center in Japan from April 21st to 25th. CIQTEK, with its independently developed Scanning NV Probe Microscope (SNVM), will showcase innovative achievements in the field of extremely weak magnetic fields. We sincerely invite experts and teachers attending the conference to visit CIQTEK's booth, experience the charm of cutting-edge technology, explore cooperation opportunities, and jointly promote advances in magnetism and related disciplines.   The Asian Union of Magnetic Societies International Conference is held once every two years. Since its establishment in 2008 by magnetic societies from China, Japan, Korea, and Taiwan, it has become an important platform for exchanges in the field of magnetism and magnetic materials in the Asia-Pacific region.     The conference aims to promote in-depth cooperation in this field and enhance the influence of the Asia-Pacific region in the global field of magnetism and magnetic materials. At that time, experts, scholars, and representatives from companies from all over the world will gather together to discuss cutting-edge scientific research in magnetism, the latest research achievements, and future development trends.   CIQTEK's SNVM, developed for scanning NV probe microscopy, utilizes nitrogen-vacancy (NV) color centers in diamond as the core sensing element. Through quantum coherent manipulation, it achieves ultra-high detection sensitivity at the single-nuclear-spin level. Compared to traditional magnetic imaging devices, it breaks through the sensitivity and resolution limitations of traditional techniques in the detection of weak electric/magnetic fields. The single-atom-sized sensor greatly enhances spatial resolution and enables high-precision electromagnetic imaging and spectroscopic analysis at the nanoscale, providing a powerful microscopic detection tool for multidisciplinary research.   CIQTEK focuses on core technologies in precision measurement and is deeply involved in the development of high-end scientific instruments. Its main business covers providing key devices and equipment for multiple industries. In 2023, CIQTEK developed the low-temperature version of SNVM for the first time globally. It can measure the electromagnetic properties of materials in the temperature range of 2 to 300 K and, when paired with a three-axis vector magnet, greatly expands the application scenarios of SNVM. Currently, more than ten units of this product have been successfully delivered, with users including Peking University, Tsinghua University, the Institute of Physics, Chinese Academy of Sciences, and City University of Hong Kong, among other top research institutions.
