If you need to study theoretically the adsorption and desorption kinetics of one-dimensional nanostructures, Wolkenstein theory can help you, even in the case of nanostructures with some precautions.
I prepared one dimensional nanostructure..I studied literature for quantum dots with adsorption and desorption kinetics. I don't know about the same thing in 1D and 2D. If you know, give me some idea Kai Fauth.
Do you want to keep sectret what your 1D nanostructure really is? The reason I ask is that before trying to give some answer, I want to make sure, that a "one-dimensional" is really what we'll want to talk about. And what is it you want to adsorb and desorb from your nanostructure?
And I am sure there is a vast amount of literature on adsorption/desorption kinetics available. Do make a literature search and choose review articles. Conceptionally, things will be very similar in 1D compared to 2D. Chances are not bad it will be simpler (sometimes, though, that's not true).
You might want to share what articles on QDs with adsorption and desorption kinetics you have studied.
Do you already have an idea what kind of an experiment you will be doing?
Thank you for your answer Kai Fauth. I prepared 1D nanorods. I am not having adsorption and desorption kinetic articles of one dimensional nanorods. Kindly send me some review articles for 1D and 2D nanostructures related to gas sensor applications. thank you.
Dear Amutha Ayyachamy, I would have to search such articles the same way as you do, I have nothing ready at hand.
In general, adsorption and desorption studies exist in great abundance in the surface science literature. Here also, you will find that there is a certain variety of techniques available for scientific study of the phenomena associated with this. Many of these would not be practical for gas sensing devices.
But then, learning about adsorption and desorption kinetics as such and making it practical for some kind of sensor you wish to develop are two different things, of course.
Let me explain why I insist on knowing more about your "1D rods". Imaginge you have something truly one-dimensional, which to me means that motion is only possible along one coordinate, not along another. If, for example two molecules encounter each other on this 1D-"track" then they cannot move across each other unless by QM tunneling. That will certainly strongly influence diffusion dynamics, which usually is a significant part of adsorption/desorption kinetics (the normal case is that a molecule adsorbs, moves around a bit and then desorbs again). Sou you might want to determine for good whether you have something strongly asymmetric - by dimensions (e.g. aspect ratio of the rods) or (exactly or approximately) one-dimensional (either by having one track only or a large anisotropy of diffusion constants).
Having written the above I remember having heard a talk on strongly anisotropic diffusion on rod-like structures a couple of years ago. If I am lucky, I can find out who gave the talk at the time and what really was the topic...
Finally to your sensor application: gas sensing could occur via changes to molecules you can then detect (essentially chemistry, you have some catalyst and this produces a molecule you can detect) or via changes of the rods which you can detect -- maybe also a combination of both. In the latter cases you have to somehow "connect" to the nanorods in order to detect the changes (you could change its conductivity and then require terminals to measure it; you could detect their Mie scattering and record changes etc.) The environment could be gaseous or liquid. In all cases you will need to consider adsorption/desorption kinetics in some form. I just wondered what really you are pondering (1st it's interesting and 2nd it may help make my or others' comments more helpful).
Above, you wrote: "I studied literature for quantum dots with adsorption and desorption kinetics." Would you be willinig to let me know which these are?
There's an additional thought: your (whatever) 1D nanostructures will be attached or deposited somehow on a substrate. Ideally adsorption/desorption would not take place there. That may prove a difficult thing to achieve, though. So you will be looking for a method able to discriminate between desirable and undesirable parts of your specimens.
This makes me think that maybe a combination of pulsed gas jets and some kind of element specific electron spectroscopy might be an option.
There are two scientists I know to have worked with such arrangements, you might want to cross check their papers: R. Denecke and P. Steinrück (they have partly published together). there will be others, too, but I am not an expert in the field - these two are the ones I happen to know.
