Design of website's header image

We are struggling to find an image that will fit into our templates header and will represent what we need. I'm attaching the screenshot of the header (the height of header is 100px). The image needs to fit into right side of the header. The company is Chemistry Consulting. The best that we expect from the image is: - Should contain periodic table (part of it) It should be understandable, that it is a periodic table. - It must represent "Problem Solving" - It should represent Science, Research and Industry (may be any kind of chemistry related tool will do it). Note: It would be nice to have the part of periodic table area where Niobium and Tantalum are. (Nb and Ta)
