The constraints of energy supply have been a long-term threat to the sustainable development of China. Technological progress and innovation are essential to helping solve this problem. Research and development （R＆D） stock plays a key role in technological progress and innovation. Through comparisons with some other countries, it is found that China has fallen behind in the R＆D stock for energy technology. The R＆D stock can be improved by two means： one is putting capital and human resources in those strategically key fields; the other is taking advantage of the R＆D resources from abroad. The strategically key fields include energy saving techniques, energy materials, the manufacture of key equipment and new energy resources.

目的设计合成单磷酸脂质A(monophosphoryl lipid A,MPLA)的衍生物,考察其作为新冠病毒疫苗佐剂的开发潜力及C⁃1或C⁃6′位取代基对其活性的影响。方法以商业易得的葡萄糖胺为起始原料,经糖基化、缩合、磷酰化和氢化等反应完成目标化合物的合成。以临床应用的铝佐剂为阳性对照,将所得化合物与RBD⁃hFc重组蛋白新冠疫苗合用,于第0天和第14天经肌肉注射免疫小鼠。然后,分别在初次免疫后的第14、28、42、90天采血,通过检测抗体滴度与亚型、抗体血清抑制RBD结合ACE2的能力及中和抗体水平评价了目标化合物作为佐剂的免疫活性。结果合成得到5个MPLA的衍生物,产物及中间体结构经NMR和HRMS确证;生物活性测试结果表明,化合物1具有比铝佐剂更优的佐剂活性,化合物3和4的活性与铝佐剂相当。结论MPLA衍生物具有作为新冠病毒疫苗佐剂的开发潜力;初步构效关系分析表明,将MPLA的C⁃1位羟基以甲氧基和氨基替换会降低其活性,而将其C⁃6′的羟基以氨基取代可以提高活性。

登月飞船、航天飞机走下神坛之后,经济制约造成一系列太空探索困境,依然是太空技术和产业发展面临的主要问题,清除太空碎片等太空公共事务呼唤更加紧密的国际合作。鉴别、预测和运用颠覆性太空技术的难度不低于技术发明本身;我国两弹一星、载人航天的系统运作机制只是应用机制,我们缺少真正意义上的颠覆性技术研发机制;缩短颠覆性太空技术研发者与应用者之间的距离,是我国发展太空技术的当务之急。SpaceX公司在美国宇航局(NASA)的帮扶下,取得太空技术应用的历史性突破,对我国发展太空经济具有启示作用。
