Type IIA DNA topoisomerases are molecular nanomachines that alter DNA topology during essential cellular processes. The final steps of their catalytic cycle, after translocation of the transported (T-) segment into the C-gate, are still not fully understood. Here, we performed all-atom molecular dynamics simulations of several conformational states of Saccharomyces cerevisiae topoisomerase IIA, each with a T-segment inserted into the C-gate.

With the miniaturization and high-frequency evolution of antennas in 5G/6G communications, aerospace, and transportation, polymer composite papers integrating superior wave-transparent performance and thermal conductivity for radar antenna systems are urgently needed. Herein, a down-top strategy was employed to synthesize poly(p-phenylene benzobisoxazole) precursor nanofibers (prePNF). The prePNF was then uniformly mixed with fluorinated graphene (FG) to fabricate FG/PNF composite papers through consecutively suction filtration, hot-pressing, and thermal annealing.

Sustainable detoxification and advanced treatment of toxic organic pollutants (TOPs) in wastewater are essential for water reclamation and ecosystem security. Although biological treatment is a low-carbon and eco-friendly approach for TOPs degradation, its effectiveness is often limited by the high toxicity and recalcitrance of TOPs. Oxidative and reductive reactions can degrade TOPs according to their intrinsic redox potentials.
