After 400 s, there is always a low CO concentration (<1.25E-07 kg/kg) area in region I. The ventilation causes the diffusion of low CO concentration area from region I to the corner of the L-shaped utility tunnel. The CO concentration at the air inlet a is always kept at a low level.

The computed diffusion coefficients of CO 2 are in good agreement with experimental data. Analyses of hydrogen bonding and the solvent's structural and dynamic properties reveal that the change of CO 2 diffusion coefficient is closely associated with the diffusional behavior of the solvent water itself, as a result of changes in the number and strength of hydrogen bonding interactions among

Diffusion (av latinets diffusio, av diffundere, "utbreda") är den spontana spridningsprocess som äger rum när något, oftast gaser eller vätskor, med en egenskap skilt från omgivningen sprids, blandas och jämnas ut. Ofta orsakas diffusion av något slags slumpvandring . Ett exempel på detta är när salt sprider sig jämnt i en lösning. Diffusivity, mass diffusivity or diffusion coefficient is a proportionality constant between the molar flux due to molecular diffusion and the gradient in the concentration of the species (or the driving force for diffusion). Diffusivity is encountered in Fick's law and numerous other equations of physical chemistry. CO-Diffusion. Sauerstoff und Kohlendioxid wird durch Diffusion zwischen der Luft in den Alveolen und dem Blut ausgetauscht.

The difference in the amount of CO between in- and exhaled gas is a measure for the diffusion coefficient (TL CO) which divided by the alveolar volume yields the transfer coefficient for CO (K CO). The diffusion capacity is the technique that measures the ability of the respiratory system for gas exchange, thus allowing a diagnosis of the malfunction of the alveolar-capillary unit. The most important parameter to assess is the CO diffusion capacity (DLCO). New methods are currently being used … Diffusion mellan P O 2 och P CO 2 i alveolär respektive pulmonellt blod ökar vid ansträngning och ger en accelererad diffusion. Vissa typer av mediciner (ex.

All-solid-state Li-ion batteries (ASS-LIBs) are expected to be the next-generation battery, however, their large interfacial resistance hinders their widespread application. To understand and resolve the possible causes of this resistance, we examined mutual diffusion properties of the cation elements at LiCoO2 (LCO) cathode/β-Li3PS4 (LPS) solid electrolyte interface as a representative

70,73 This suggests that the binding energy of CO on Cu may be weakened under alkaline conditions, promoting faster desorption of the formed *CO intermediate more than under neutral conditions. 70 The selectivity towards CO does eventually decrease in In this paper, fine-grain WC/Co tools were utilized in dry turning of the Ti-6Al-4V alloy. The wear modes of the cutting tools at different cutting speeds were analyzed. The diffusion behavior between the cutting tool and the workpiece was studied in detail based on the Auger electron spectroscopy (AES) depth profile technology. The diffusion wear mechanism was revealed.

När det omvandlas blir koncentrationen av koldioxid mindre i blodet och därför kan diffusionen av koldioxid från vävnaden till blodet i kapillären fortlöpa. Läs mer om denna princip nedan.
