Multi-armed nanorods and nanobars of semiconductor selenium were simultane- ously synthesized in the light of biomineralization process through bio-membrane bi-templates of rush at room temperature. The multi-armed nanorods are 60 nm in diameter and 1.5 μm in length; the nanobars are 150 nm in diameter and 1000—1100 nm in length. The XRD pattern indicates that these nanocrystals were crystallized in the hexagonal structure with lattice constants a = 0.437 nm, c = 0.495 nm. The possible formation mechanism was investigated.

Semiconductor CdS nanotubes with a small ratio of length to diameter and nanospheres were simultaneously synthesized in the light of bio- mineralization process through living bio-membrane bi-template of mungbean sprouts at room tempera- ture. The outside diameter of the nanotube is 220- 240 nm and the inner diameter is 200-220 nm, the length is up to 600-700 nm and the ratio of length to diameter is 2:1. The nanoshpheres are 25 nm in diameter and well distributed. The XRD pattern indi- cates that these nanocrystals were crystallized in the cubic structure with lattice a = 5.818 ?. The optical properties of the products are illustrated, and their possible forming mechanism is explored.

老年髋部骨折具有高发生率、高致残率、高病死率的特点,已成为威胁老年人健康的公共卫生问题。手术是老年髋部骨折的首选治疗手段,但围术期下肢深静脉血栓(DVT)的发生率极高,一旦进展为肺栓塞将显著增加患者死亡风险。针对这一问题,临床指南和专家共识均强调对此类患者应积极采取基础预防、物理预防、药物预防的全面预防措施。在此预防体系中,基础预防是物理和药物预防的基石。目前,临床上对于基础预防措施缺乏统一明确的标准。为此,中华护理学会骨科专业委员会与中国医疗保健国际交流促进会骨科分会护理学部组织相关护理专家,结合循证医学证据和专家临床经验,制订《老年髋部骨折患者围术期下肢深静脉血栓基础预防专家共识(2024版)》,共提出10条推荐意见,以规范老年髋部骨折患者围术期下肢DVT的基础预防措施,促进患者康复。

轻子散射实验是探索核子与原子核结构的理想工具。中国电子离子对撞机(Electron Ion Collider in china,EicC)建议书设想在已开建的强流重离子加速器装置(High Intensity heavy ion Accelerator Facility,HIAF)的基础上,升级质子束流为20 GeV的极化束流,并建造2.8~5 GeV极化电子束流,从而实现质心系能量为15~20 GeV的双极化电子-离子对撞。EicC设计的亮度为(2~4)×10^33cm^-2·s^-1,质子束流极化率达到70%,电子束流极化率达到80%。该装置除了能提供极化轻离子束流(例如:氦-3)外,也可产生非极化重离子束流(碳-12~铀-238)。EicC将聚焦核子海夸克部分子结构、原子核物质结构与性质、奇特强子态三个方面的物理研究。高亮度、高精度的对撞机有助于精确地测量核子结构函数并对核子进行三维成像,揭示强相互作用的动力学规律;原子核部分子分布包括核子短程关联以及原子核介质效应同样是该提案的重要科学目标;EicC能区接近重味夸克产生阈值,在研究重味强子谱方面拥有低背景的独特优势,有助于发现研究新的奇特强子态。质子质量起源问题也可以通过重味矢量介子的产生来研究。为了完成上述物理目标,我们将利用最先进的探测器技术建造接近全立体角覆盖的EicC对撞机谱仪。在准备EicC白皮书的过程中,我们得到世界各国专家的支持。EicC的物理与已有的实验和美国即将建设的EIC中的物理项目相互补充。EicC的建成及运行有望引领前沿的中高能核物理研究,使我国在加速器和探测器先进技术等领域实现跨越式发展,为我国核物理与强子物理以及相关科学领域提供大型综合实验平台与人才培养基地。
