Advanced Sustainable Systems, Volume 10, Issue 1, January 2026.A microwave‐assisted approach yields Zr‐MOF/Ag4P2O7 heterostructures with superior solar responsiveness and efficient charge‐carrier separation. The hybrid photocatalyst rapidly degrades dyes and fluoroquinolone antibiotics into less toxic species under visible‐light. Comprehensive optical, mechanistic, and phytotoxicity analyses reveal its robustness,

Natural Cross-Pollination in Lettuce, Lactuca sativa L. [PDF]
Nature, 1958 SELF-FERTILIZATION in Lactuca sativa L. is commonly regarded as being complete, although the inflorescences are visited by insects and the possibility of cross-pollination does occur1,2. Some indication that natural crossing takes place was provided by the fact that progenies raised from seed, taken from random plants grown in adjacent plots of a trial
