Two new highly oxygenated spirosesquiterpene lactones, ligulactones A (1) and B (2), and one known sesquiterpenoid, 1beta,10beta-epoxy-6beta-isobutyryloxy-9-oxo-furanoeremophilane (3), were isolated from the roots of Ligularia fischeri. Their structures and relative configurations were elucidated...
摘要: The results of design and investigation of microstrip high-temperature superconducting (HTS) 12-pole filter and 4-pole band-pass filter are presented. The filters are based on a set of double-resonator structures.关键词: band-pass filters high-temperature superconductors microstrip couplers ...
For the first time, a comprehensive overview is given of all metal-mediated base pairs, the experimental conditions under which they were established, and the experimental techniques used to prove their existence. In addition, all experimental nucleic acid duplex structures involving metal-mediated ...
