The natural products synthesized by organisms that were living a long time ago gave rise to their molecular fossils. These can consist of either the original unchanged compounds or they may undergo peripheral transformations in which their skeletons rema
Super high molecular weight copolymers of AM/NaA/AMPS were prepared by oxidation-reduction [OR-P(AM/NaA/ AMPS)] and controlled radical polymerization [CR-P(AM/NaA/AMPS)]. The resulting copolymers were fully characterized , and the reacti... YF Ji,· Cao,YW Zhu,... 被引量: 0发表: 202...
In the cytokinin pathway, the expression of two A-ARR genes, one B-type response regulator (B-ARR) and one cytokinin response 1 (CRE1) was downregulated. In the GA pathway, the expression of one GA receptor gene, gibberellin insensitive dwarf 1 (GID1), and one GA-responsive gene, ...
当镍钛或不锈钢电极浸泡在电解质溶液中,合金表面开始钝化形成保护性的TiO2或富含Cr/ Fe的氧化物薄膜,这会显著抑制了合金的进一步溶解,从而提高了合金的腐蚀稳定性。通过比较Eb-Ecorr值评估合金在不同蛋白溶液中的点蚀敏感性变化,通过比较Eb-Eprot值来评估再钝化的过程。阳极极化区段出现的明显转折代表了金属的溶解和...
Growing concern has arisen from the quasi-exponential increase in the numbers and quantities of man-made chemicals that presently are in current use, and their potential effects on human health, especially their delayed effects on degenerative diseases s
Sex determination is essential for the sexual reproduction to generate the next generation by the formation of functional male or female gametes. In mammal
