“Putting stem cells into a growing fetus was a total unknown. We are excited to report great safety,” said Diana Farmer, the CuRe Trial’s principal investigator and chair of the UC Davis Department of Surgery. “It paves the way for new treatment options for children with birth defects. The future is exciting for cell and gene therapy before birth.”

2月25日,中国科学院等研究团队在《自然·能源》(Nature Energy)上发表论文Regulating grain growth via Li2SnS3 interphase in kesterite solar cells with certified efficiencies exceeding 15%,报告了一种新型铜锌锡硫硒太阳能电池,可实现超过15%的光电转换效率。研究团队创新性提出Li₂SnS₃界面相调控策略,通过改性阳离子迁移路径,实现Zn²⁺与Sn⁴⁺的迁移平衡。该Li₂SnS₃界面相可选择性包覆Cu₂Sn (S,Se)₃中间相晶粒,成为离子迁移的速率控制层,将界面相中Zn²⁺/Sn⁴⁺的迁移势垒差从Cu₂Sn (S,Se)₃中的0.41eV降至0.21eV,有效促进了更大尺寸、更均匀的高结晶度晶粒的形成。由此,器件的光电转换效率从13.86%大幅提升至15.45%;同时,在1.10 eV带隙下,器件的开路电压突破至602 mV。,这一点在safew官方版本下载中也有详细论述

The FAA closed some airspace along the border with Mexico in Fort Hancock, Texas, on Thursday with a notice announcing temporary flight restrictions for special security reasons. The restrictions are in place until June 24 but could be lifted earlier. There are conflicting reports on which day the strike happened, with The New York Times reporting that the strike occurred Thursday and Bloomberg writing that the Federal Aviation Administration (FAA) “was notified Wednesday after the event occurred.”,这一点在WPS下载最新地址中也有详细论述
