Front Cover: The cover page of article 2300337 by Filipe Natalio and co-workers shows the chemosynthesis of a glucose derivative depicted in the upper part of the illustration. This last compound is fed to a floating cotton ovule in vitro culture (central illustration), becoming integrated into the fibers (blue dots). These modified fibers show increased mechanical properties, as depicted with the clamps in the lower part of the illustration.

低氟取代度对棉纤维性能的影响

封面： Filipe Natalio 及其同事撰写的文章 2300337 的封面页显示了插图上部所示的葡萄糖衍生物的化学合成。最后一种化合物被喂入漂浮的棉花胚珠体外培养物（中心插图），并融入纤维（蓝点）。这些改性纤维显示出更高的机械性能，如图下部的夹具所示。
