Pan‐Frying Conditions Affect the Tocopherol Intake From Edible Oils: Results From Temperature Measurements and the Standardized Heating of an Edible Oil

Journal of the American Oil Chemists' Society, EarlyView.
High temperatures in a short time on electric stoves in private homes. Fast loss of tocochromanols using standardized conditions and a miniature heating apparatus. ABSTRACT Tocochromanols (vitamin E compounds) are essential ingredients in human nutrition. Their consumption via edible oils is considered the main source of dietary intake.

Nitric oxide generation from nitrate at the cobalt center

Bulletin of the Korean Chemical Society, EarlyView.
Deoxygenation of a cobalt(II) nitrate complex with CO(g) or PPh3 yields a Co(NO)(NO2) species, which can alternatively be generated from a cobalt mononitrosyl complex, featuring a distinct {CoNO}8 core. Abstract Herein, we report the synthesis and reactivity of the cobalt(II) nitrate complex, (acriPNP)Co(NO3) (2).

Fueling Tomorrow: Scenario Planning for the Future of Gas Stations

Business Strategy and the Environment, EarlyView.
ABSTRACT Transport electrification is reshaping the service infrastructures that mediate everyday mobility, yet most electrification scenario studies remain macrolevel and offer limited insight into how incumbent forecourt (gas‐station) networks can adapt under deep uncertainty.
