Although natural terpenoid cyclases generate polycyclic structures through cationic intermediates, alternative radical cyclization pathways are underexplored. Now an artificial radical cyclase has been prepared by anchoring a biotinylated cobalt Schiff-base complex within a chimeric streptavidin scaffold. Chemogene...
Two other environmental synthesis pathways to produce OCqC3carbon units are known but seem to be of minor relevance compared with ODA. One is selective preservation of OCqC3units in precursor (bio)molecules, such as oxygenated terpenoids62,63. The other is the unselective attack of energy-rich h...

Combining the Eg calculated in Figure S1 and the other UPS data in Figure S4, the energy level diagrams are drawn as Figure 2F, and the values are listed in Table 1. The EF of PBDB-TF:GS-ISO is deeper than those of e-TiOx, indicating the direction of built-in electric field in ...
ORRs can be divided into two reaction pathways: one is a four-electron transfer reaction to produce water and the other is a two-electron transfer reaction to form a hydrogen peroxide intermediate, which can continue to perform a two-electrons transfer to form water or directly evolve H2O2 ...
(CH4) or being exported to groundwater as dissolved organic carbon (DOC) or dissolved inorganic carbon (DIC) [2]. In fact, the soil C pool is greater than the vegetative and atmospheric C pools combined [3]. Therefore, a process-level understanding of C storage and fluxes within soils ...

The results presented in this work can be interpreted based on some proposed pathways for the formation of zeolites [39,40]. A proposed scheme for the formation of mordenite particles is shown inFigure 7. From this perspective, crystallization could occur from the organization of silicon species ...

The FDA’s regulations are the same regardless if it’s organic or conventional tampons/pads and they both have same level of absorbency. If the tampons you’re using has a plastic applicator it will contain phthalates in that plastic so why not use a tampon that has a non plastic applicat...
