Abstract Phenotypic plasticity is an important avenue by which organisms may persist in the face of rapid environmental change. Environmental cues experienced by the mother can also influence the phenotype of offspring, a form of plasticity called ma

This work uses DFT to investigate diene formation during methanol-to-olefins (MTO) via alkene-mediated and CH2O-mediated pathways in MFI and CHA zeolites. The rate controlling hydride transfer reactions were investigated with C1–C4 surface-bound al

Zeolite reactivity depends on the solvating environments of their micropores and the proximity of their Bronsted acid sites. Turnover rates (per H+ ) for methanol and ethanol dehydration increase with the fraction of H+ sites sharing six-membered rin

Turnover rates of Bronsted acid-catalyzed methanol dehydration to dimethyl ether become inhibited at high methanol pressures (>10 kPa, 415 K) on small-pore zeolites (CHA, AEI, LTA, LEV), irrespective of the distribution of framework Al and their atte
