second order desorption, n = 2, is when two hydrogen atoms on the surface desorb and form a gaseous H 2 molecule. There is also zeroth order desorption which...

surface is heated, at one point, the energy transferred to the adsorbed species will cause it to desorb. The temperature at which this happens is known as...

people because they impair the ability of a wall to desorb moisture, which quality is necessary to preserve its strength.[citation needed] Blemishes...

lifetime; after returning to the surface, it does not stick (freeze) like a water or hydrogen peroxide molecule but rather desorbs from the surface and starts...

reaction product (water molecule dimers), after which the water molecule desorbs from the catalyst surface. Catalysts enable pathways that differ from the...

will hop around the surface) or reflected. Atoms on the surface may also desorb. Controlling the temperature of the source will control the rate of material...

involves restoring the adsorptive capacity of saturated activated carbon by desorbing adsorbed contaminants on the activated carbon surface. The most common...

or electrode to prevent this. Nylons are hygroscopic and will absorb or desorb moisture as a function of the ambient humidity. Variations in moisture content...

to be due to the incoming ions weakening bonds in the sample, which then desorb by thermal activation. The hydrogen-induced sputtering of carbon-based materials...

surface chemically ( P a {\displaystyle P_{a}} ) desorb from the surface ( P b {\displaystyle P_{b}} ) move to the next precursor state ( P c {\displaystyle...

adsorbing the target gases at high pressure. The process then swings to low pressure to desorb the adsorbed material and flush the adsorbent container so that...

gaseous phase. From here, adsorbate molecules would either adsorb to the adsorbent or desorb into the gaseous phase. The probability of adsorption occurring...

target gas species at high pressure. The process then swings to low pressure to desorb the adsorbed gas. The pressure swing adsorption (PSA) process...

approaches used to analyze metabolites from biological samples.[citation needed] SIMS uses a high-energy primary ion beam to desorb and generate secondary...

H2O      (ΔH = -1165.6 kJ mol−1) One suggested mechanism is that S6 and S8 desorb from the catalyst's active sites with simultaneous formation of stable cyclic...

(see figure to the right). The product molecules then desorb from the surface and diffuse away. The catalyst itself remains intact and free to mediate further...

pulsed laser is used to desorb or ablate material from a sample and the plume of material interacts with an electrospray or plasma to create ions. Electrospray-assisted...

ranging in thickness (usually a thin, oxidized layer.) Volatile products desorb in the plasma phase and help the plasma etching process as the material...

lot of wear and reduction of the tip quality. The second way is to degrade or desorb the SAM molecules by shooting them with an electron beam. The scanning...

chemisorbed species combine (by forming bonds with each other) the product desorbs from the surface. Self-assembled monolayers (SAMs) are formed by chemisorbing...
