Modeling and computational simulation of the carbon monoxide oxidation process, taken as a key system to analyze importance dynamic description active sites into process yield, are presented in this work. To aim, formalism transport phenomena population balances used implement realistic model that involves heat exchange, transfer mass momentum, chemical reaction, catalyst deactivation. The is s...

The boron-oxygen recombination center responsible for the light-induced degradation of Czochralski silicon solar cells can be permanently deactivated by illumination at elevated temperature. In this study, we examine the impact of dopant compensation on the deactivation process. The experimental results show that the deactivation rate depends inversely on the total boron concentration instead o...

Deactivation of N-methyl-D-aspartate (NMDA) channels after brief agonist exposure determines the duration of their synaptic activation during excitatory neurotransmission. We performed patch-clamp recordings of L-glutamate responses from human embryonic kidney tumoral cells (HEK293) expressing NR1 subunit variants lacking exon 5 together with the NR2B subunit. These responses had deactivation c...

In this paper, the ethical and legal issues raised by the deactivation of implantable cardioverter-defibrillators (ICDs) in patients with terminal cancer is considered. It is argued that the ICD cannot be well described either as a treatment or as a nontreatment option, and thus raises complex questions regarding how rules governing deactivation should be framed. A new category called ‘‘integra...

Recently, Gilbert and Zare proposed that dynamical quantum effects might explain the poor performance ofclassical trajectory calculations in simulating the vibrational deactivation of excited azulene by the lighter noble gases. They proposed an experimental test: a comparison of 3He and 4He deactivation of azulene. In this Letter, the collisional deactivation of benzene, toluene and toluene-ds ...
