下一步，安徽大学磁性材料团队将继续围绕稀土资源高效利用开展系统攻关，坚持"理论指导设计、需 求牵引研发"，着力破解稀土永磁材料领域核心科学与技术问题，为提升我国关键材料国际竞争力、保 障战略资源安全贡献力量。 记者29日从安徽大学获悉，该校材料科学与工程学院王守国教授团队联合北京工业大学及稀土永磁材料 全国重点实验室，围绕高丰度稀土磁体重稀土晶界扩散技术展开深入研究，首次揭示影响重稀土扩散效 率的两大关键微观机制。相关成果日前发表于《先进功能材料》。 （文章来源：科技日报） 稀土永磁材料是新能源汽车、高端装备制造、电子信息、节能环保等战略性新兴产业不可或缺的核心材 料。当前，我国稀土资源面临镧、铈等高丰度元素大量积压与镝、铽等战略重稀土利用效率低的双重结 构性问题。推动稀土资源均衡化、高附加值利用，已成为落实国家新材料发展战略、保障产业链供应链 自主可控的重要任务。 针对这一挑战，研究团队提出创新科学假设。团队认为，高丰度稀土磁体内部化学成分异质性及复杂晶 间相结构，可能是主导并制约重稀土原子沿晶界扩散路径、速率及分布形态的关键内在机制。该构想将 工艺难题提升至材料科学层面，为设计磁体微观结构、调控扩散过程提 ...

科技日报北京12月28日电 （记者刘霞）阿尔茨海默病一直被认为不可逆转，但美国科学家开展的一项 最新研究发现，大脑能量供应失衡是导致该病恶化的重要因素。动物实验显示，通过药物恢复能量平 衡，不仅能修复受损脑组织，甚至能完全恢复晚期患病小鼠的记忆和认知功能，从而逆转疾病进程。这 项突破性发现为治愈阿尔茨海默病带来了可能，相关成果发表于新一期《细胞医学报告》杂志。 过去一个多世纪，针对阿尔茨海默病的研究大多聚焦于预防或延缓病程，极少尝试逆转已造成的损伤。 尽管投入巨大，全球尚未有任何药物以认知功能恢复为临床试验目标。 为改变这一局面，美国凯斯西储大学与克利夫兰医学中心研究团队利用小鼠模型和人类患者脑组织发 现，患者大脑难以维持一种关键细胞能量分子NAD+的正常水平，这直接推动了阿尔茨海默病的发展。 团队强调，该疗法不同于市面上常见的NAD+补充剂。后者可能使体内NAD+水平异常升高，反而增加 癌症风险；而P7C3-A20是一种精准调控药物，能帮助细胞在压力下维持NAD+平衡，避免其水平失 控。 这一发现不仅为阿尔茨海默病的治疗开辟了新方向——从"延缓衰退"转向"功能恢复"，也为后续人体试 验奠定了基础。 下一步， ...
