  • 基于化学处理并以来自玉米壳副产物的微晶纤维素强化的大豆蛋白基膜: 该研究探索了一种大豆蛋白基膜的开发,该膜以来自玉米壳副产物的微晶纤维素强化,并以亚硫酸钠进行化学处理。产生的膜具有增强的机械性质,从而成为可生物降解包装的切实可行的选择(Zhang et al., 2024)(Zhang et al., 2024)。

  • 原始细胞(primitive cell)中能量采集过程的建模:亚硫酸盐氧化驱动的质子传输穿越双层该论文为原始细胞中的能量采集过程建模,重点关注了亚硫酸盐氧化驱动的质子传输穿越双层。这些发现有助于我们理解早期细胞生物能量学以及亚硫酸盐在这些过程中的作用(Paula et al., 2024)(Paula et al., 2024)。

Nitrone spin traps such as 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) are commonly used for free radical detection. Though proven examples are rare, artifact formation must be considered. For example, the Forrester-Hepburn mechanism yields the same radical adduct as that formed by genuine radical
