Computationally aided design of defect-appended aliphatic amines for CO2 activation within UiO-66
, 2022 We report CO2 adsorption and subsequent formation of carbamic acid within defective UiO-66 functionalised with aliphatic amines. Periodic Density Functional Theory (DFT) calculations confirm the activation of CO2 with the aliphatic amines and the ...

Photocatalytic α-Alkylation of Amines with Alkyl Halides
, 2020 a-Branched amines represent essential building blocks for organic synthesis. They are traditionally prepared through nucleophilic addition to imines. These methods often require highly reactive organometallic reagents and proceed under rigorous air- and ...

Amines, Astrocytes, and Arousal [PDF]
Neuron, 2017 Amine neurotransmitters, such as noradrenaline, mediate arousal, attention, and reward in the CNS. New data suggest that, from flies to mammals, a major mechanism for amine transmitter action is to raise astrocyte [Ca2+]i and release gliotransmitters that modulate neuronal activity and behavior.
