Recent progress of thermocatalytic ammonia synthesis via an associative mechanism
Fundamental ResearchAmmonia is an important chemical and a carrier of hydrogen. Artificial nitrogen fixation mainly relies on the Haber−Bosch process driven by thermo-catalysis, where the activation of N2 usually follows a dissociative route.

Tryptophan metabolite atlas uncovers organ, age, and sex‐specific variations
FEBS Open Bio, EarlyView.Tryptophan metabolites were analyzed across twelve organs, the central nervous system, and serum in male and female mice at three life stages. We found tissue‐, sex‐, and age‐specific differences, including increased indole‐3‐pyruvate and kynurenine in aging males.

FEBS Open Bio, EarlyView.CAF‐mediated immunosuppression in ovarian cancer is driven by IDO1, reducing T‐cell function. Inhibiting IDO1 restores T‐cell proliferation and cytotoxicity, increases cancer cell apoptosis, and may help overcome CAF‐induced immune suppression in high‐grade serous ovarian cancer. Targeting IDO1 may improve antitumor immunity.

Xylene isomerization over zeolite catalysts [PDF]
, 1994 Paraxylene is used as a raw material for the production of the synthetic fibers. The production of paraxylene can be obtained by isomerization of xylene using zeolites as catalyst. At equilibrium, the mixture of xylene contains 24% para, 24% ortho and 52%
