A Chemoreceptor That Detects Molecular Carbon Dioxide

The Amygdala Is a Chemosensor that Detects Carbon Dioxide and Acidosis to Elicit Fear Behavior

The amygdala processes and directs inputs and outputs that are key to fear behavior. However, whether it directly senses fear-evoking stimuli is unknown. Because the amygdala expresses acid-sensing ion channel-1a (ASIC1a), and ASIC1a is required for normal fear responses, we hypothesized that the amygdala might detect a reduced pH. We found that inhaled CO(2) reduced brain pH and evoked fear be...

An optimized molecular potential for carbon dioxide.

An optimized molecular potential model for carbon dioxide is presented in this paper. Utilizing the established techniques of molecular-dynamics and histogram reweighting grand canonical Monte Carlo simulations, this model is demonstrated to show excellent predictability for thermodynamic, transport, and liquid structural properties in a wide temperature-pressure range with remarkable accuracie...

Molecular Cluster Cations of Carbon Monoxide and Carbon Dioxide

This thesis deals with the metastable decay and the surface scattering induced fragmentation in the hyperthermal energy range of relatively weakly bound molecular cluster cations. With (CO)n and (CO2)n two related model systems were chosen for a systematic size dependent study. Surface impact experiments were carried out with stainless steel and SiO2 covered Si(100) surfaces. Results were obtai...

Carbon Dioxide Sorption in a Nanoporous Octahedral Molecular Sieve

We have performed first-principles density functional theory calculations, incorporated with van der Waals interactions, to study CO2 adsorption and diffusion in nanoporous solid – OMS2 (Octahedral Molecular Sieve). We found the charge, type, and mobility of a cation, accommodated in a porous OMS-2 material for structural stability, can affect not only the OMS-2 structural features but also CO2...
