The atmospheric lifetimes of CFC 11 and CFC 12
Geophysical Research Letters, 1982 A two‐dimensional (2‐D) chemical model of the atmosphere is used to investigate the stratospheric removal rates of the Chlorofluorocarbons CFC 11 (CFCl3) and CFC 12 (CF2Cl2). Assuming equivalent vertical transport rates, one‐dimensional (1‐D) models are shown to overestimate the atmospheric lifetime of CFC 11 by ∼10% because of their neglect of ...

Monitoring Chlorofluorocarbons in Potential Source Regions in Eastern China
Atmosphere, 2020 Recent studies have indicated that Eastern China might be a potential source region of increased atmospheric chlorofluorocarbons (CFCs). To investigate this possibility, a field measurement was carried out from October to December 2017 for identifying ...

Microenvironment Engineering as a Design Principle for Suppressing Catalyst Metal Loss
Angewandte Chemie, EarlyView.Under ionomer‐containing microenvironments, nonporous carbon supports enhance the retention of dissolved platinum ions, whereas porous carbon supports promote pore‐confined redeposition and mitigate net platinum loss. ABSTRACT Stability losses in platinum electrocatalysts arise from dissolution, redeposition, and restructuring processes that are ...

Assessing the Impact of Ih Conductance on Cross-Frequency Coupling in Model Pyramidal Neurons
Frontiers in Computational Neuroscience, 2020 Large cortical and hippocampal pyramidal neurons are elements of neuronal circuitry that have been implicated in cross-frequency coupling (CFC) during cognitive tasks. We investigate potential mechanisms for CFC within these neurons by examining the role

Recall and reconsolidation of contextual fear memory: differential control by ERK and Zif268 expression dosage. [PDF]
PLoS ONE, 2013 Compelling evidence points to the existence of independent cellular processes involved in the consolidation and reconsolidation of memory. For instance, a double dissociation has been reported between hippocampal Extracellular-Regulated Kinase-1/2 (ERK1 ...
