It should be about 4 pages long, plus a page or so for images. Your paper should include about four high quality images or X-ray maps. Prints off the laser printer in the SEM lab are certainly high enough quality. Here are the parts that should be in your paper, and can also be used as a model for your talk . Writing a good title is difficult.
Most papers only have their titles read as few people bother to read a paper with a boring title.
It should describe the problem the paper addresses, and the solution to the problem. You don't need to say why you reached the conclusions you did in the abstract. Here is the place to talk about what the data means. Normally this would be the place to put the data into a scientific framework, but for this paper keep that part fairly brief. Really like an expanded version of the abstract.
