    Mohammad Abdi (R) learns about TCM herbal drinks from a doctor at Ningxia Chinese Medicine Research Center in Yinchuan, northwest China's Ningxia Hui Autonomous Region, on Aug. 15, 2026. Mohammad Abdi, a 26-year-old Iranian student, came to China in 2023 to study clinical medicine at Ningxia Medical University. He was introduced to traditional Chinese medicine (TCM) at an early age. After seeing his uncle receive cupping therapy in Iran, he became curious about this traditional medical practice. Later, as a medical student in China, he had the opportunity to take professional TCM courses. On weekends, Abdi visits Ningxia Chinese Medicine Research Center to experience various TCM therapies. "I was a gym rat, so I initially thought TCM practices were too simple to be effective," he said. However, as he learned more about TCM, he was impressed by its depth and effectiveness. He recommended Baduanjin, a traditional Chinese breathing and stretching exercise, to his fellow international students, while he especially enjoys tuina massage combined with cupping therapy, which helps relieve the stress of his studies and clinical internship. For Abdi, TCM is more than a way to treat diseases; it is also a health philosophy that can be integrated into daily life. He believes ordinary people can benefit from TCM-based wellness practices, while professional doctors can use TCM techniques to treat patients. TCM is now expanding its global presence and joining the worldwide conversation on health and lifestyle. Inspired by growing interest in Chinese lifestyles overseas, Abdi hopes to continue exploring TCM and become a skilled doctor, helping more people in his hometown benefit from traditional Chinese medicine.

。     8 月 25 日消息，科技媒体 Tom's Hardware 昨日（8 月 24 日）发布博文，报道称京都大学研究团队研发出新型碳化硅（SiC）晶体管，采用标准离子注入工艺制造，可在 600℃（873 K）下工作。援引博文介绍，该晶体管采用商业芯片工厂普遍使用的“离子注入”（ion implantation）工艺打造，相关成果于 8 月 17 日发表在《APL Electronic Devices》。

二 | 研究团队选择“结型场效应晶体管”（JFET）结构，并将栅极置于沟道下方，形成底栅（bottom-gate）布局。离子注入过程中，部分掺杂原子会沿晶体通道深入目标区域之外，形成“沟道效应”尾部。传统顶栅结构难以补偿这一影响，导致设计阈值电压与实测值相差超过 2 V。

三 | 底栅结构可捕获偏离预定深度的掺杂原子，让该偏差在 400℃ 下缩小至 0.1 V 以内。该科研团队为了减少高温漏电，团队还加入“双阱”（double-well）隔离结构。该结构通过 pn 结隔离单个器件，避免依赖下方半绝缘碳化硅衬底。参考广告声明：文内含有的对外跳转链接（包括不限于超链接、二维码、口令等形式），用于传递更多信息，节省甄选时间，结果仅供参考，包含外链的文章均包含本声明。
